exact relation identity, two independently derived +labelled-transition-system authorities, a closed participant/audience +projection, complete finite carrier bounds, a revisioned theorem profile, +machine-check and counterexample contracts, a runtime-mapping boundary, +independent reproduction, requirement ownership, and dependency-ordered +implementation work. + +Waivers: issue #811 is design authority. It does not deliver either executable +LTS, an equivalence result, a proof certificate, a runtime mapping, backend +conformance, noninterference, or opacity. Those results remain blocked on +SEM-232 child work. + +## Context + +ADR-081 distinguishes strong and weak bisimulation from finite probes, +matching traces, and projected-history equality. ADR-085 and SEM-230 define +participant/audience-relative labels, projection, exact-cut policy, +declassification, memory, order, and policy noninterference. ADR-095 separates +decision, state cut, projection, delivery, and observation. API-423 defines the +portable participant-crossing occurrences; RUN-319 implements the reference +mediation boundary. + +Those authorities do not state one exact pair of systems for a bisimulation +result. They also do not define which runtime bookkeeping is hidden, whether +hidden divergence matters, or what machine-check evidence would be final. +Schema equality, matching digests, projected traces, and bounded probes cannot +close that gap. + +Issue #811 evaluates five possible theorem surfaces. The complete reference +runtime and uncontrolled backend implementations are too broad for a first +claim. A policy-pair or purge lemma would be useful only after its own closed +policy carrier and information-flow preservation theorem exist. The crossing +kernel is the smallest surface that already has semantic, contract, and +runtime mapping authorities. + +## Decision + +### 1. Select the crossing-kernel theorem + +The first target is the complete finite abstract SEM-230 participant-crossing +LTS versus an independently derived formal concrete API-423/RUN-319 +crossing-kernel LTS. The exact theorem profile is +`participant-crossing-dpbb-finite-v1@rev1`. + +The theorem to be machine-checked by downstream work is: + +> The declared initial states of +> `sem-230-participant-crossing-abstract@rev1` and +> `api-423-run-319-crossing-kernel@rev1` are +> divergence-preserving branching bisimilar under +> `participant-crossing-projection@rev1`, over the complete reachable carrier +> of `participant-crossing-dpbb-finite-v1@rev1`. + +This is a theorem about two formal systems. A separate runtime-realization +claim must show that the live reference runtime maps to the concrete formal +system. + +### 2. Add an exact relation identity + +Behavioral-relation taxonomy revision `rev6` adds +`divergence-preserving-branching-bisimulation`. It is not an alias for ordinary +weak bisimulation. It preserves the branching point around visible behavior +and requires related states to agree on explicit infinite `tau` behavior. + +For LTSs `L_A` and `L_C`, a symmetric relation `R` satisfies the branching +transfer clauses when every step from one related state is either: + +- a `tau` step whose target remains related to the other state; or +- matched after a finite `tau` path on the other side whose intermediate + branching state remains related, followed by the same visible label to a + related target. + +The explicit-divergence condition additionally requires an infinite `tau` +path that remains related to one opposite state to have matching divergent +behavior on the opposite side. The formal specification fixes the exact +transfer clauses and the checker semantics. + +### 3. Close the first finite profile + +The profile fixes one synthetic participant, audience, controller, episode, +request identity, and backend-independent crossing surface. It has two exact +policy cuts, five input classes, six decision values, one total +per-participant order, finite replay state, and finite delivery state. + +`policy.cut.advance` is a visible environment action from `p0` to `p1`. +Controller handoff is excluded by fixing controller `c0`. Time, probability, +fairness, true concurrency, and partial order are excluded. The carrier is the +complete reachable fixed point of the declared finite transition schemas, not +a depth limit or sample. + +The visible alphabet includes request, permit, deny, unsupported, +transformation, declassification, delivery, observation, later-cut replay +rejection, and policy-cut advance. A redacted occurrence remains visible. + +Only these semantic classes are hidden: + +- `internal.validate`; +- `internal.resolve-policy-cut`; +- `internal.resolve-capability`; +- `internal.prepare-record`; and +- `internal.atomic-commit`. + +The exporter maps those five classes to the single checker action `internal`; +no other label is hidden. Every internal crossing path has a decreasing finite +progress rank, so a positive result must not erase an implementation-side +infinite internal loop. + +### 4. Keep model construction independent + +The abstract transitions are hand-reviewed formal authority derived from +SEM-230. The concrete transitions are independently derived from API-423 and +RUN-319 crossing stages. Both use the same closed label/projection profile, but +must not be generated from one table that already asserts correspondence. + +The live-runtime mapping is a third artifact. It covers authenticated subject +binding, exact-cut resolution, independent gates, effective capability +support, transformed subjects, API-423 ordering, expected history heads, +atomic commit, refusal side effects, idempotency, and replay. Source digests +detect drift but do not prove the mapping. + +### 5. Select an evidence-led toolchain + +The finite equivalence decision uses mCRL2 `202607.0`: + +```text +ltscompare --equivalence=dpbranching-bisim --tau=internal \ + abstract.aut concrete.aut +``` + +The child implementation must acquire the tool through checksum-verified +repository or immutable-container provenance, run without a shell or +verification-time network, and record exact input, source, profile, mapping, +tool, result, state-count, transition-count, mutation, and artifact digests. +The design does not invent an archive checksum before acquisition. + +TLC remains suitable for auxiliary finite deadlock, replay, atomicity, and +progress properties, but property agreement is not bisimulation. Isabelle/HOL +is the proportionate future route for a parameterized or unbounded +coinductive theorem. The finite mCRL2 result is classified as `model-check`, +not `proof`. + +A successful exit is not treated as a certificate the tool did not emit. The +exact pinned inputs plus a clean independent reproduction are mandatory. +Negative mutations require durable safe counterexamples; pure divergence +failures require an independent checked negative-result path if the selected +tool mode does not emit a diagnostic formula. + +### 6. Separate every assurance claim + +The formal result preserves visible branching behavior, enabled visible +choices, explicit termination/refusal, structural deadlock, and explicit +divergence for the named profile. It makes no claim about: + +- the live runtime until differential mapping evidence exists; +- any backend until declaration, realization, and conformance evidence exists; +- SEM-230 policy noninterference or SEM-231 opacity without a separate + profile-matching preservation theorem; +- time, probability, fairness, controller handoff, true concurrency, partial + order, or inputs outside the complete named carrier; or +- the complete reference runtime beyond the crossing kernel. + +Scientific-completeness and public proof claims remain blocked until the +positive result is independently reproduced. + +### 7. Allocate requirement-backed work + +SEM-232 (canonical Ground Control requirement id +`860b0b1e-55cc-42e6-9da8-b7eeeab7172c`) owns the machine-checkable result and +remains DRAFT. Downstream work is ordered: + +- #971 — independent abstract and concrete formal models; +- #972 — reference-runtime mapping after #971; +- #973 — mutation and counterexample corpus after #971 and #972; +- #974 — finite equivalence decision after #971, #972, and #973; +- #975 — independent reproduction after #973 and #974; and +- #976 — scientific and public documentation after #974 and #975. + +## Alternatives Considered + +Use strong bisimulation. Rejected: finite validation, policy resolution, +capability lookup, record preparation, and commit bookkeeping are legitimately +internal to the selected participant projection. + +Use ordinary weak bisimulation. Rejected: it can erase the branching point +before permit/refuse behavior and does not by itself preserve hidden +divergence. + +Compare the abstract semantics with the complete live runtime. Rejected: the +first profile does not cover every HTTP error, scheduler, persistence, +backend, audit, timestamp, and operational path. + +Compare two backend realizations. Rejected: backend internals are not governed +and cannot be declared `tau` by convenience. + +Generate both LTSs from one correspondence table. Rejected: that would make the +equivalence result self-confirming. + +Use matching temporal properties as the equivalence result. Rejected: two +systems can satisfy the same selected properties without being bisimilar. + +## Consequences + +RAES gains an exact, reproducible first bisimulation target and an honest path +to a positive machine-checkable result. The cost is a deliberately narrow +carrier and three independently reviewed boundaries: abstract model, concrete +model, and runtime mapping. + +Revision `rev6` defines the relation and claim surface only. The catalog +assurance remains deliberately unproved and not model-checked until the child +program publishes its evidence. + +## References + +- [ADR-081](adr-081-behavioral-relation-taxonomy-and-claim-discipline.md) +- [ADR-085](adr-085-participant-information-flow-and-control.md) +- [ADR-095](adr-095-participant-decision-epoch-state-cut-and-delivery-semantics.md) +- [Participant-crossing formal authority](../../../specs/formal/participant-semantics/participant-crossing-bisimulation.md) +- [Candidate comparison](../../research/participant-bisimulation/candidate-comparison.md) +- [Proof-tool decision](../../research/participant-bisimulation/proof-tool-decision.md) +- R. van Glabbeek, B.

Requirement-backed proof work must not begin until +its owning DRAFT Ground Control authority exists. + +This note records repository-wide architecture guardrails for the bisimulation +design and proof program. It is guidance only: it does not select or prove a +theorem, publish a relation profile, amend an ADR or formal specification, +choose a proof tool on behalf of the design record, create a requirement or +child issue, change runtime behavior, certify a backend, or establish +bisimulation. + +## Decisive Current-State Findings + +RAES has the semantic, contract, runtime, claim, and evidence carriers needed +for one bounded participant-control bisimulation result. It does not yet have a +normative proof LTS, an executable relation profile, or a proof-result artifact. + +- ADR-081, `specs/formal/behavioral-relations/README.md`, and + `contracts/concept-authority/behavioral-relations-v1.json` are the only + relation taxonomy. Revision `rev5` defines strong and weak bisimulation but + deliberately records no implementation, model check, or proof. +- `BehavioralClaimBindingModel` already separates relation identity, carriers, + observation projection, quantifier/evidence scope, relation-parameter + profile, assurance axis, evidence, limitations, and nonclaims. Universal + scopes already require model-check or proof evidence. +- The relation-profile seam is not complete. The shared binding currently + validates only that a required profile ref/revision pair is present; it does + not resolve or validate the referenced profile. Issue #811 must coordinate + with the SEM-231 closed-profile work instead of creating a + bisimulation-only registry or treating an opaque string as a checked profile. +- ADR-085, ADR-095, and SEM-230 revision `sem-230/rev2` define the abstract + state coordinates, closed label classes, exact-cut policy state, + participant/audience-relative projection, `tau` treatment, memory, + declassification, scheduler/environment, order, and noninterference + boundary. +- `implementations/python/tests/sem230_information_flow_model.py` is explicitly + a test-local bounded falsification helper. It is not the normative SEM-230 + LTS and cannot become a theorem carrier by renaming it or exhausting its + current examples. +- API-423 `ParticipantCrossingOccurrenceModel` and its contextual validator + define portable request, decision, transformation, delivery-attempt, + delivery, observation, and audit evidence. RUN-319 crossing mediation adds + authenticated subject binding, capability admission, exact-cut resolution, + fail-closed gates, idempotency, replay protection, append-only history, and + atomic persistence. +- The live runtime includes generated operation ids, wall-clock timestamps, + backend capability declarations, audit-only facts, and implementation + bookkeeping. Those are not automatically semantic observations or `tau`. + Each must be retained, redacted, or hidden by the selected profile. +- ASR-535 finite enumeration and backend probes are falsification and + conformance evidence. They do not prove a relation. Proof status, reference + runtime realization, and backend conformance remain separate axes. + +The missing boundary is therefore a revision-pinned formal model pair plus a +checked mapping from SEM-230/API-423/RUN-319 carriers into those models. The +gap is not another participant DTO, policy engine, runtime store, backend +profile, conformance runner, exception hierarchy, or logger. + +## Candidate-Surface Architecture Fit + +The design must evaluate all five issue candidates, but their repository fit is +not equal: + +| Candidate | Repository fit and guardrail | +| --- | --- | +| Abstract SEM-230 LTS versus the complete reference runtime | High value but currently too broad for a first claim unless the design inventories every enabled participant-control path, HTTP/error observation, policy change, scheduler, persistence, and backend interaction. A crossing-kernel theorem must not be promoted to whole-runtime equivalence. | +| Two policy configurations | Feasible only after both configurations are closed, revisioned policy carriers. Equal projected histories or one opacity witness is not configuration bisimulation. | +| Abstract crossing operation versus concrete contract/runtime refinement | Best-bounded primary surface. SEM-230, API-423, and RUN-319 already expose its state, labels, gates, evidence, and mapping seams. The theorem must still distinguish a formal concrete model from live-runtime realization. | +| Two backend realizations | Unsuitable as the first theorem. The current backend-comparison claim surface prohibits bisimulation, and uncontrolled backend internals cannot be hidden without a governed projection and divergence argument. | +| High-action-hidden system versus purge/restriction | Useful as a separately named noninterference lemma. It must not turn policy noninterference into bisimulation by definition or claim opacity/noninterference without its own preservation argument. | + +The evidence-led default is candidate 3 over one complete finite profile. A +design may choose another target, but it must show that its carrier and mapping +surface are no broader than the evidence and do not depend on uncontrolled +backend internals. + +## Architecture Decisions And Guardrails + +### Use an exact relation, not generic “weak equivalence” + +The likely crossing-kernel fit is divergence-preserving branching +bisimulation under a named participant/audience projection: + +- concrete policy resolution, validation, capability lookup, record + preparation, and atomic commit can take finite internal steps; +- the participant-visible branching point before permit, deny, transform, or + unsupported must remain observable as branching structure; +- hidden divergence must not be equated with finite internal work; and +- deliberate terminal states, deadlock, failed resolution, and successful + completion must remain distinguishable. + +This relation is not currently a catalog identity. If selected, add a distinct +governed relation or an explicit catalog evolution that represents its exact +semantics; do not label it `weak-bisimulation`, silently strengthen the current +weak relation, or encode divergence sensitivity only in prose. Strong +bisimulation remains available only if every internal step is intentionally +matched. Ordinary weak bisimulation requires a separate justification because +it can forget the branching and divergence facts that matter here. + +A profile fixes at least: + +- left and right model ids, revisions, digests, state spaces, and initial-state + relation; +- participant, episode/memory scope, audience, controller/authority, policy + decision/revision/cut, projection revision, and visible order; +- complete input and label alphabets, including redacted occurrence labels and + the exact `tau` set; +- enabledness, environment, scheduler, nondeterminism, fairness, progress, + termination, deadlock, divergence, stuttering, and retry/replay semantics; +- concurrency, order, time, probability, declassification, transformation, + policy-change, and controller-handoff treatment; +- relation witness/invariant family and preservation/non-preservation results; + and +- finite carrier domains and a declaration that they are the complete + quantified carrier when a finite equivalence decision is the final result. + +Redacted occurrence, denial, withholding, unsupported status, omission under a +declared opportunity, and a sanitized error can be visible labels. They are +not `tau` merely because content is absent. Audit/evidence facts may be hidden +from a participant profile while remaining visible to an auditor profile. + +### Bound the first theorem without weakening its truth + +A scientifically useful first profile may fix one participant, one audience, +one episode/memory scope, one logical total order, a finite source/action +domain, finite exact-cut policy states, deterministic environment inputs, and +no wall-clock or probability semantics. It should include the security-bearing +permit/deny/unsupported/transform or declassify outcomes and retry/replay +boundary that distinguish RUN-319 from a trivial schema machine. + +The profile must state excluded dimensions as excluded: + +- the current per-participant lock may justify sequential interleaving for the + selected runtime surface, not concurrent or partial-order equivalence; +- a fixed policy revision excludes policy-change behavior but does not make + later-revision replay safe by assumption; +- a fixed controller excludes handoff behavior but does not establish handoff + preservation; +- an untimed profile excludes latency and timeout observations; and +- finite non-probabilistic branching says nothing about probability measures, + strategies, or fairness outside the fixed profile. + +A finite result is final only for its complete finite carrier. A depth bound, +sampled schedule, truncated state space, property test, or finite trace corpus +remains intermediate evidence. + +### Keep abstract model, concrete model, and runtime mapping independent + +The abstract LTS is governed formal authority derived from SEM-230. The +concrete LTS is a formalization of the selected API-423/RUN-319 crossing +kernel. Live Python execution is a separate realization lane. + +Do not generate both LTSs from one table that already asserts matching +transitions; that makes the result circular. The safe boundary is: + +- one hand-reviewed abstract transition authority; +- one independently derived concrete carrier or deterministic exporter; +- one shared, closed label/projection profile; and +- differential mapping tests that drive the real runtime boundary and compare + its typed occurrences, history heads, dispositions, and side effects with + the concrete model. + +The mapping must account for: + +- `ParticipantCrossingIntent`, exact policy resolution, every independent + semantic gate, API-407 effective support, and transformed subject identity; +- API-423 predecessor/order/context invariants and delivery/observation + separation; +- authenticated caller, target, participant/controller, and audience binding; +- `RuntimeSnapshot` crossing/control/behavior histories, expected history + heads, atomic commits, audit facts, and unchanged-state guarantees on + refusal; +- idempotent replay at the same cut and rejection after the cut advances; and +- safe abstraction of UUIDs, wall-clock timestamps, host paths, and + audit-internal details only when the profile proves they are outside its + observer. + +Source-code digests and commit pins detect review boundaries; they do not prove +the mapping. Avoid a Python-AST scraper that mistakes implementation shape for +semantic authority. + +### Reuse one relation-profile and claim-binding authority + +The behavioral catalog remains the only relation registry and +`BehavioralClaimBindingModel` remains the only claim-binding authority. The +selected theorem needs one closed, revisioned relation-parameter profile +resolved by the shared validator. + +Coordinate that profile carrier with SEM-231. The common header should own +relation id, carrier refs/digests, observation projection, label partition, +quantification, model dimensions, and assurance/evidence refs. Exact +relation-specific parameters may use a closed discriminated variant. Do not +create parallel `BisimulationProfileModel` and `OpacityProfileModel` +registries, reuse a GOV-920 semantic profile or backend profile, or place a +serialized mini-language in `subject`, `limitations`, `metadata`, or +`evidence_boundary`. + +Advancing the relation taxonomy requires all current revision producers, +fixtures, claim surfaces, reader-facing relation definitions, and claim-policy +tests to move together. Adding a relation entry does not by itself require a +new published schema version when the catalog shape is unchanged. Adding a +portable profile or evidence shape does require the normal +`ContractModel`/schema/publication/compatibility decision. + +One proved or model-checked profile must not promote every use of the generic +relation. The claim binding records the exact positive assurance axis and +evidence. The catalog definition keeps profile-specific limits explicit. + +### Select tooling by the theorem, not by repository language + +The proof-tool decision record must compare at least these routes: + +- **Explicit-state equivalence:** mCRL2 `ltscompare` directly supports strong, + branching, divergence-preserving branching, weak, and + divergence-preserving weak bisimilarity and explicit action hiding. Its + documentation describes counterexamples for strong and branching + bisimulation; the decision record must verify counterexample support for the + exact selected mode or pair the checker with an independently checked + negative-result path. This is the best current fit for a complete finite + crossing profile. +- **Temporal/model checking:** TLC is an explicit-state checker for finite TLA+ + models and safety/liveness properties. It is useful for deadlock, replay, + atomicity, and progress checks, but it is not a bisimulation decision merely + because both systems satisfy the same temporal properties. A relational + product construction and checked invariant would have to be explicit. +- **Machine-checked relational proof:** Isabelle/HOL supports coinductive + definitions and coinduction, making it proportionate if the target becomes a + parameterized or unbounded theorem. It has a higher toolchain and proof + maintenance cost than the first finite carrier. + +Relevant official tool facts: + +- +- +- +- + +The design record may select another established environment, but it must +demonstrate exact relation support, deterministic noninteractive execution, +available witness/counterexample behavior, CI viability, version pinning, +licensing, and independent reproduction. A positive process exit is not a +proof certificate unless the tool documents that artifact. If the selected +checker emits no positive witness, exact pinned inputs plus an independent +reproduction path are mandatory; mutation failures still require a durable, +safe counterexample corpus. + +### Publish evidence through existing artifact and workflow patterns + +Reuse the protocol/bundle/execution-snapshot pattern in +`docs/research/formal-semantic-validation/` and the claim discipline in +`BehavioralClaimBindingModel`. A proof evidence record must bind: + +- theorem/profile/relation/taxonomy ids and revisions; +- left/right model, mapping, projection, and source-revision digests; +- complete domains or explicit bounds and state/transition counts; +- tool name, version, binary/archive checksum or container digest, fixed + command, platform limits, and result; +- relation witness/certificate when available, or the independently + reproducible result; +- counterexample/mutation ids and artifact digests; +- exact assurance axis (`model-check` for a finite equivalence decision, + `proof` only for a proof checked as such); +- limitations, preserved properties, and explicit nonclaims; and +- independent reviewer command and expected digest/result. + +Do not overload `BackendConformanceReport`, API-423 occurrences, the existing +scheduler-isolation evidence carrier, `RuntimeSnapshot.metadata`, operation +details, or `AuditEvent` as a proof result. Do not publish a generic +proof-result schema until a portable consumer justifies it. Domain evidence +can remain a +revisioned, checked research/formal bundle while the shared claim binding +provides the portable claim surface. + +The checker enters the canonical nox/workflow graph through a named session, +not an issue-local shell script. Tool pins belong in `tools/tool_versions.py` +or a full-digest CI/container pin; acquisition follows the checksum/provenance +pattern used by repo-managed tools. The equivalence result and drift checks are +blocking evidence for any positive claim. Scientific-completeness and public +documentation changes wait for independently reproduced evidence. + +### Keep bisimulation, noninterference, opacity, and realization separate + +Bisimulation preserves only the properties justified by the selected relation, +projection, and state/atomic-proposition mapping. + +- A participant-observation bisimulation can support a named noninterference or + opacity result only with a separate theorem showing that the selected + low-equivalence, secret/release policy, and observer facts are preserved. +- Bisimulation does not automatically imply SEM-230 policy noninterference, + because noninterference compares high variations, adaptive low strategies, + memory, purge, and declassification schedules. +- It does not automatically imply SEM-231 opacity, because opacity quantifies + secret and nonsecret possible points in observer information cells. +- A theorem between formal LTSs does not establish that RUN-319 realizes the + concrete model. Differential mapping evidence is necessary and remains + separate from backend declaration, native realization, and conformance. + +## Canonical Incumbents To Reuse + +| Concern | Canonical incumbent and required use | +| --- | --- | +| Formal-method classification | ADR-007/018, `specs/formal/assurance-policy.yaml`, and `specs/formal/assurance-fulfillment.yaml`; retain FM3 abstract-state-machine and proportional evidence requirements. | +| Relation authority | ADR-081, `specs/formal/behavioral-relations/README.md`, `BehavioralRelationCatalogModel`, `BehavioralRelationDefinitionModel`, `BehavioralClaimBindingModel`, `load_behavioral_relation_catalog()`, and `validate_behavioral_claim_binding()`. | +| Claim policy | `tools/check_behavioral_relation_claims.py`, relation/catalog tests, catalog fixtures, claim surfaces, and every current `rev5` producer. | +| Abstract semantics | ADR-022, ADR-085, ADR-095, SEM-230 revision 2, participant runtime semantics, exact-cut policy, dynamic projection, memory, order, labels, and explicit nonclaims. | +| Crossing contracts | API-423 crossing models, typed subjects/policies/gates/losses, `validate_participant_crossing_occurrence_context()`, and crossing-history snapshot/transition validators. | +| Runtime mapping | `ParticipantCrossingIntent`, policy resolution and mediation, ingress/egress boundaries, `RuntimeControlPlane`, strict subject binding, API-407 capability admission, and safe runtime diagnostics. | +| Persistence/order | `RuntimeSnapshot`, `ControlPlaneStore.commit_participant_transition()`, in-memory/local stores, expected history heads, scoped idempotency/fingerprints, append-only histories, and `AuditEvent`. | +| Backend boundary | API-407 feature support, required-contract mapping, `resolve_participant_feature_support()`, manifest/profile validation, and explicit declared/effective strength. | +| Conformance | ASR-535 semantic/runtime/backend lanes, `run_target_conformance()`, participant-policy harnesses, `ConformanceCaseResult`, `BackendConformanceReport`, and final cross-field validation.

Proof tooling must not become +a runtime dependency. + +## Cross-Cutting Layers And Security Posture + +1. **Model/profile input gate.** Committed formal sources are trusted, + revision-pinned inputs. Generated or external JSON uses bounded UTF-8 reads, + duplicate-member rejection where applicable, closed `ContractModel` shapes, + root-confined paths, exact revisions/digests, and one semantic + cross-reference validator. No executable expression, import path, remote + URL, or open metadata bag is a model parameter. +2. **Relation and claim gate.** Catalog id/revision, relation id, projection, + resolved profile, carrier refs/digests, quantifier scope, assurance axis, + evidence scope, limitations, and nonclaims must agree before evidence is + serialized. A string profile ref or green tool exit cannot bypass this join. +3. **Runtime authentication gate.** Pure model checking makes no HTTP or caller + authorization claim. Runtime mapping tests still use + `ControlPlaneSecurityConfig.strict_defaults()`, `ControlPlaneIdentity`, + role and target binding, participant/controller or audience binding, + request bounds, and audit denials. Authentication remains separate from + participant authority and visibility. +4. **Policy/capability gate.** Caller, target, participant authority, action + admission, visibility, marking, declassification, backend support, and + transformation validity remain independent and fail closed. + `NOT_APPLICABLE` at a required gate is unresolved, not permit. Declared and + effective backend strength remain separate state facts. +5. **Persistence/replay gate.** Mapping evidence includes append-only typed + history, expected-head atomic commit, unchanged backend/participant state on + refusal, safe decision/audit evidence, and same-cut idempotent replay. + Proof/check results never enter runtime snapshots, metadata, operation + details, or a side database. +6. **Secret-handling gate.** Models, profiles, fixtures, witnesses, + counterexamples, diagnostics, logs, audit, CI artifacts, and review records + contain synthetic bounded values and safe ids/refs/digests only. They exclude + credentials, tokens, prompts/private memory, hidden answers/world state, + policy bodies, raw participant/backend payloads, rejected values, native + objects, connection data, environment dumps, and host paths. Hashing a + secret-bearing value does not make it suitable evidence. +7. **Diagnostic/error-envelope gate.** Expected failures use bounded stable + codes and safe model/profile coordinates. Raw Pydantic `input_value`, tool + stderr, exception text, tracebacks, model payloads, or counterexample secret + values do not enter portable evidence, audit, CLI summaries, or HTTP + responses. Unexpected HTTP errors retain + `{"detail":"internal server error"}`. +8. **OS/process gate.** Invoke a fixed allowlisted checker without a shell, + with safe repo-relative file arguments, deterministic locale/working + directory, bounded time/memory/output, and no network during verification. + Put no model content, policy, witness, participant value, credential, or + report in argv, environment variables, filenames, stdout/stderr, shell + history, or host logs. Version output and binary/archive checksum or + container digest become evidence. +9. **Artifact-publication gate.** Validate the complete evidence record before + atomic writing. Use canonical JSON, safe run ids, root confinement, content + digests, stable artifact names, and explicit retention. CI uploads the + bounded evidence bundle, not the workspace, caches, tool binary, environment, + or unrestricted raw logs. +10. **Schema/governance gate.** A catalog revision, shared profile resolver, + published schema, proof evidence checker, assurance fulfillment entry, + lineage statement, and documentation outcome move through their existing + policy gates. No accepted ADR is edited without ADR-059, no hand-governed + schema changes without its publication entry, and no requirement-backed + child opens before DRAFT authority. + +## Extensibility Seam + +The stable seam is one resolved behavioral-relation profile plus one +proof-evidence bundle: + +```text +catalog relation + -> closed relation profile + -> left/right model + projection + mapping digests + -> claim binding + axis-specific evidence bundle +``` + +The relation profile is parameterized by participant/audience, carrier +revisions, label/projection partition, model dimensions, initial relation, and +quantifier domain.

It is guidance only: it does not change a +schema or model, realize or execute a trial, add a scheduler, persist an +artifact, add fixtures/tests, or define an implementation plan. + +ADR-065 and ADR-084 remain authoritative. The existing experiment run is the +only archival run root, the admitted trial plan is immutable execution intent, +and the existing SDL/processor/runtime path remains the only scenario +lifecycle. + +## Architecture decisions and prerequisite gaps + +- The public seam consumes one fully revalidated `AdmittedTrialPlanModel`, one + `plan_entry_id`, and the exact digest-matched family, task, manifests, + realization envelope, profiles, and associated artifacts pinned by that + plan. It does not accept a detached entry, raw experiment authoring input, + caller-supplied replacement bindings, or an unchecked Python object. +- Validate the complete plan and its canonical digest before resolving the + entry. Then rerun the owning cross-artifact joins against the concrete pinned + inputs. A structurally valid entry extracted from a stale, tampered, + incomplete, or mismatched plan is not executable. +- `raes.select_scenario_family()` is the SDL-owned one-entry selection and + admission gate. It already applies the complete recorded outcomes and routes + through `instantiate_scenario()` and `admit_instantiated_scenario()`. The + integration must call it and must not reconstruct its payload mutation, + target resolution, relation validation, binding, or exception translation. +- Extend the existing `InstantiationProvenance` surface rather than add a + trial-realization root. Canonical instantiated-snapshot bytes must commit to + the exact family identity/digest, admitted plan id/digest, entry id/digest, + preallocated `run_id`, coordinate, selections, and admitted bindings. Every + repeated value is equality-checked against the plan entry; it is not a + second authority. +- `canonical_instantiated_sdl_bytes()` and + `canonical_instantiated_sdl_digest()` remain the snapshot identity + authority. Do not hash YAML, `repr`, `model_dump_json()`, mutable validation + flags, a filesystem path, or an unadmitted scenario. +- Continue through `compile_scenario_runtime_model()` and + `raes_processor.planner.plan()`. Processor-plan provenance uses the existing + `provisioning_plan_model()`, `orchestration_plan_model()`, and + `evaluation_plan_model()` projections, their published contract versions, + RFC 8785/JCS canonical digests, and the digest-matched + `ProcessorManifestV2Model`. Do not claim a portable digest for the internal + `RuntimeModel` or `ExecutionPlan` dataclass by serializing `asdict()` or + Python object state. +- The effectful executor delegates to one existing execution transport per + attempt. In-process execution uses a fresh per-attempt `RuntimeManager` and + its `plan()`/`apply()`/`destroy()` lifecycle. A control-plane deployment may + instead submit the same typed plan projections through + `RuntimeControlPlane`; it must not also call `RuntimeManager.apply()` for the + same work. No integration layer calls backend protocol methods directly. +- Attempt context is supplied to the one-entry executor. A started, + effect-capable attempt receives one opaque `execution_attempt_id`, distinct + from `run_id`, scheduler job id, operation id, workflow run id, snapshot id, + and backend-native id. Transport replay reuses the attempt and idempotency + identity; a policy-authorized later attempt receives a new attempt id but + retains the admitted entry and `run_id`. +- Extend `ExperimentRunModel` minimally with a closed, typed trial-realization + linkage rather than create a second run or provenance root. The linkage must + bind the plan and entry identities/digests, logical coordinate + (condition/block/replicate when present), instantiated-snapshot digest, + processor-plan artifact refs/digests, and the attempt refs that contributed + to the governed terminal run outcome. +- `TrialCleanupReceiptModel` remains the immutable per-attempt authority for + primary disposition versus cleanup disposition. Failed or unverified cleanup + remains visible even when the archival run outcome succeeded and prevents + resource reuse. It is not collapsed into a deviation string or inferred + from `RuntimeManager.destroy()` success. +- Extend the owning experiment cross-artifact validation beside + `validate_experiment_run_against_task()` and + `validate_experiment_study_against_tasks_and_runs()`. Given the admitted + plan, concrete run records, and attempt/cleanup evidence, it must reconcile + every admitted entry with zero or more explicit attempts and no more than + one governed terminal archival outcome. Zero-attempt entries remain visible + through the plan; they do not require placeholder runs. +- Planned, instantiated, processor-derived, backend-realized, observed, and + derived facts stay on their existing surfaces. The admitted plan states + intent; the canonical scenario snapshot states instantiated meaning; typed + processor plans state derived operations; runtime snapshots and receipts + state live realization; evidence records state observations; derived + measures and study analysis state interpretation. + +Two repository gaps are prerequisites, not invitations for local shortcuts: + +- There is no canonical bounded external loader for + `admitted-trial-plan-v1`. Any file/API ingress must be byte-bounded, + duplicate-key rejecting, and closed-model validating in the owning contracts + layer before execution. It must not use an unbounded `json.load()` or add an + APTL-only parser. +- `InstantiationProvenance` and `ExperimentRunModel` do not yet carry the + required admitted-entry/attempt integrity spine. Until their owning, + published contracts and cross-artifact validators carry it, an adapter must + not encode the missing linkage in metadata, notes, tags, paths, logs, or + generic references and claim completion. + +## Canonical incumbents to reuse + +- **Lifecycle and identity:** ADR-055, ADR-065, ADR-068, ADR-074, ADR-084, + `specs/formal/scenario-variation-trial-realization/README.md`, + `AdmittedTrialPlanModel`, `AdmittedTrialEntryModel`, + `AdmittedInstantiationProvenanceModel`, `TrialCoordinateModel`, + `ExperimentRunModel`, `ExperimentStudyModel`, and RFC 8785/JCS helpers in + `raes_contracts.canonical`. +- **SDL selection and snapshot:** the exact `ExpandedScenario` family, + `ExpandedScenarioBindingTargetResolver`, `select_scenario_family()`, + `instantiate_scenario()`, `admit_instantiated_scenario()`, + `InstantiationProvenance`, `InstantiatedScenarioSnapshot`, + `canonical_instantiated_sdl_bytes()`, and + `canonical_instantiated_sdl_digest()`. +- **Bindings and secrets:** `AdmittedBindingModel`, + `ExperimentBindingDescriptorModel`, `RealizedBindingProvenanceModel`, + `validate_experiment_binding_targets()`, participant/apparatus configuration + result validators, `SecretReferenceBindingValueModel`, + `RuntimeFactBindingPlane`, and `RuntimeEnvironmentVariable` sensitivity and + omission rules. +- **Processor artifacts:** `compile_scenario_runtime_model()`, + `raes_processor.planner.plan()`, `ProvisioningPlanModel`, + `OrchestrationPlanModel`, `EvaluationPlanModel`, the three + `raes_contracts.plan_projection` helpers, processor/backend manifest + compatibility, realization-envelope membership, and artifact-requirement + admission. +- **Execution and operations:** `RuntimeManager.plan()`/`apply()`/`destroy()`; + where the deployment uses the control plane, + `RuntimeControlPlane.submit_provisioning()`, + `submit_orchestration()`, `submit_evaluation()`, `get_operation()`, + workflow cancellation/timeout/compensation helpers, + `OperationReceipt`, `OperationStatus`, and request + idempotency/fingerprints. +- **Attempts, cleanup, and archival evidence:** `TrialCleanupPlanModel`, + `TrialCleanupReceiptModel`, `validate_trial_cleanup_receipt()`, + `ExperimentRunTraceabilityModel`, `ExperimentEvidenceRecordModel`, + `ExperimentDerivedMeasureModel`, `ExperimentInvalidationModel`, + augmentation/realized-form disclosures, and associated-artifact refs, + checksums, sensitivity, and redaction/loss disclosure. +- **Persistence and observability:** `ControlPlaneStore`, + `LocalControlPlaneStore`, `ControlPlaneOperationRecord`, append-only + `AuditEvent`, `operational_apparatus_summary()`, `is_valid_run_id_label()`, + `run_artifact_path()`, and the existing atomic artifact writers. Live + operation durability and archival run/evidence storage remain separate. +- **Publication and workflow:** ADR-009, ADR-019, ADR-061, + `specs/authority/authority-boundary.yaml`, + `contracts/schema-publication-manifest.json`, per-contract publication + entries and fixtures, `.ground-control.yaml`, `.gc/plan-rules.md`, + `noxfile.py`, `tools/generate_contract_schemas.py`, + `tools/check_generated_schemas.py`, `tools/check_schema_publication.py`, + `tools/check_repo_policy.py`, `tools/check_requirement_governance.py`, and + `tools/verify_all.py`. + +The modules under `raes_runtime.participant_scheduler*` schedule participant +actions inside one already running scenario. They are not trial-attempt +identity, batch scheduling, run provenance, or a reusable worker framework. + +## Cross-cutting layers the design must pass + +1. **Ingress and shape gate.** Bound bytes before parsing, reject duplicate + JSON members, reconstruct `AdmittedTrialPlanModel`, reject extras through + `ContractModel(extra="forbid")`, check contract/profile compatibility, and + recompute `plan_digest` and every entry digest. Never execute a caller's + deserialized model without reconstruction. +2. **Plan and cross-artifact gate.** Resolve the requested map key to the + embedded `plan_entry_id`; join plan/family/task/spec/binding-set/artifact/ + manifest/envelope refs to exact concrete digest-matched inputs; resolve the + cleanup plan and stochastic controls; and reject stale capability or + envelope drift. No fetch, substitution, fallback, or repair occurs inside + validation. +3. **SDL admission gate.** `select_scenario_family()` validates every complete + outcome, target write, relation, and whole selected scenario before the + ordinary instantiation/admission path. Entry bindings and resulting + `InstantiationProvenance` must be equal to the admitted values, and the + canonical snapshot digest is recomputed before processor use. +4. **Processor/backend gate.** Compile the admitted instantiated scenario, + project all three typed plans through the existing contract models, rerun + planner diagnostics, manifest compatibility, artifact availability, + realization-envelope, target binding, and backend `validate()` gates. + Backend refusal or drift is an explicit failed/deviated attempt, never + permission to substitute bindings or apparatus. +5. **Authentication and authorization gate.** Any API reuses + `ControlPlaneSecurityConfig.strict_defaults()`, bearer or verified-proxy + identity, mutating/read roles, target scoping, request-size guards, + idempotency/fingerprint conflicts, and append-only audit. Plan visibility, + artifact dereference, secret resolution, execution, cancellation, cleanup, + evidence publication, and run publication are separately authorized + actions. +6. **Secret and configuration gate.** Portable plans and provenance carry + governed secret references only. Resolve a secret at its authorized + run-local typed sink; never turn it into a factor, parameter value, digest + input, selection, artifact summary, diagnostic, or audit detail. Ambient + environment, worker defaults, backend defaults, or mutable global config + cannot change the admitted scenario or run identity. +7. **OS/process exposure gate.** Use per-attempt private work/storage + namespaces, safe bounded names, containment-validated paths, fixed argv, + controlled working directories, no shell interpolation, bounded + subprocesses, private seed/material files, credential-free connection URIs, + ownership-safe backend names, and redacted captured output. Tokens, + credentials, secret refs, parameter maps, raw plans, environments, native + handles, and backend output do not enter argv or process titles. +8. **Timeout, retry, cancellation, and cleanup gate.** Attempt timeout is + supplied from `AdmittedExecutionControlModel`; workflow timeout, + participant deadlines, logical scenario time, API timeouts, cleanup + obligation timeouts, and lease expiry remain distinct. Unknown effect state + reconciles the persisted attempt/operation before a retry. Every terminal + path triggers the declared cleanup obligations and validates the resulting + receipt independently of the primary outcome. +9. **Error-envelope gate.** Expected failures become bounded, + canonically ordered `Diagnostic`/`DiagnosticModel` records with governed + codes, domains, JSON-pointer addresses, and safe fixed messages. Backend + adapters report exception type without exception text; HTTP retains the + redacted 500 body. Raw Pydantic inputs, selected values, secret locators, + plans, host paths, stderr, native ids, environment, and tracebacks are not + rendered. +10. **Persistence, logging, and archival gate.** Persist operational + correlation needed for idempotent recovery in the canonical operational + store: safe plan/entry/run/attempt ids, operation ids, deadlines, and + cleanup disposition. Store canonical plan/snapshot/processor/run/evidence + artifacts through immutable, checksum-bound artifact surfaces. Logs and + audit carry only safe ids, digests, versions, stages, counts, outcomes, and + durations; they are not provenance authority. +11. **Run/study reconciliation gate.** Revalidate the run against its task, + apparatus manifests, scenario snapshot, admitted entry, attempts, cleanup + receipts, evidence, and stochastic controls. Revalidate the study against + its tasks, admitted allocation, and runs. Condition, replicate, selected + bindings, draw addresses, `run_id`, and terminal outcome must agree across + every repeated surface. + +## Extensibility seam + +The seam is a pure entry-realization operation followed by an effectful +attempt executor. Its explicit inputs are the sealed plan identity, entry id, +exact pinned artifacts, selected runtime target, opaque caller-owned +`execution_attempt_id`, idempotency identity, and admitted deadline/cleanup +policy. Its outputs are existing typed artifacts and safe diagnostics: +admitted instantiated snapshot, canonical digests, typed processor-plan +projections, operation/attempt evidence, cleanup receipt, and the existing run +record when terminal. + +A future scheduler, distributed worker transport, backend, artifact store, or +resume mechanism replaces only dispatch, transport, or storage adapters. It +must not change entry realization, snapshot identity, processor-plan +projections, attempt/run identity rules, run/study validation, cleanup +semantics, or scoring boundaries.

The GitHub issue is the delivery contract. This note records +architecture guardrails only; it does not implement the split. + +## Current-Tree Reconciliation + +The issue's historical module path (from the retired pre-#884 SDL namespace) no +longer exists. The current, sole SDL namespace is `raes` (ADR-093 and the #884 +hard cut), so the +target is `implementations/python/packages/raes/module_registry.py` and the +stable import is `raes.module_registry`. The current file is 897 lines. + +ADR-015's amended source-file cap is **500 lines**, not the issue's historical +600-line figure. The split must therefore leave every non-test Python source +file in `raes/module_registry/` at or below 500 lines and remove the current +`raes/module_registry.py` entry from `tools/policy/oversized_allowlist.yaml`. + +## Decisions And Boundaries + +- Convert the module into a package with a deliberately thin `__init__.py` +facade. It must re-export every existing supported import name used by +`raes.composition`, `raes_cli.sdl`, tests, documentation, and any declared +public API. Do not introduce a retired-namespace alias, compatibility import hook, +or second resolver entry point. The current module has no `__all__`; do not +add a restrictive one that changes existing star-import semantics. +- Partition by existing responsibility, not by arbitrary line count: (1) + Pydantic policy/lock and resolved-module models plus deterministic lockfile + persistence; (2) local/locked/OCI resolution orchestration; (3) OCI + transport, trust, signature, digest, cache, and archive safety boundary; and + (4) OCI-layout publishing. Shared digest/version/descriptor helpers belong + with the smallest existing dependency direction, rather than in a new + generic utility layer. +- The OCI boundary must remain one cohesive security boundary. Its URL parsing, + trust-policy lookup, explicit timeout, capped reads, JSON decoding order, + manifest/config/bundle digest checks, signature binding, archive-member + validation, cache containment, and root-file check must not be split across + parser, CLI, composition, runtime, or backend modules. +- Preserve the exact existing model and error authority: `SDLModel`, + `ImportDecl`, `ModuleDescriptor`, `TrustPolicy`, `RegistryTrustPolicy`, + `Lockfile`, `LockRecord`, `ResolvedModule`, `SDLParseError`, and + `SDLValidationError`. The refactor creates neither a second schema/DTO nor a + registry-specific exception or logging path. + +## Compatibility Guardrails + +`test_sdl_module_registry.py` imports `raes.module_registry` as a module and +patches/uses private OCI seams on that module (`urlopen`, `_OCI_LIMITS`, +`_json_request`, `_bytes_request`, `_safe_tar_members`, +`_extract_bundle_to_cache`, `_oci_cache_dir`, `_sha256_digest`, +`_signable_payload`, and `_verify_signatures`). These are existing in-repo +behavioral seams even though they are private. + +The package facade must preserve their names and patch behavior without +modifying pre-existing tests. Simple `from .oci import name` re-exports are +insufficient when an implementation function resolves a patched dependency +from its own module globals. Keep a narrow facade-compatible indirection (or +an equivalent single injected dependency seam) so patches to +`raes.module_registry.urlopen` and `raes.module_registry._OCI_LIMITS` affect +the request and archive paths exactly as before. Do not solve this by changing +tests, exposing a broad new public test API, or duplicating OCI logic. + +## Cross-Cutting Obligations + +- **Trust/config:** continue to parse `raes-trust.yaml` only through + `TrustPolicy`/`RegistryTrustPolicy` Pydantic validation; retain defaults and + `extra="forbid"` behavior inherited from `SDLModel`. +- **Supply chain and filesystem:** preserve registry allowlisting, + insecure-HTTP opt-in, version selection, digest pins, lockfile checks, + Ed25519 verification, bounded reads, archive validation before extraction, + cache-root containment, and cache-hit root-file validation. A move must not + alter error order or create a bypass. +- **Parser/composition:** continue to use the existing normalized-source + parser, `ImportDecl`/`ModuleDescriptor` validation, and `resolve_import()` / + `ResolvedModule` contract. `raes.composition` remains the sole expansion + consumer; it must not learn OCI internals. +- **Error and process exposure:** preserve `SDLParseError`/Typer envelopes; + do not add logging, environment configuration, subprocesses, credentials, + secrets in argv, or response/body/key material in errors. +- **Build and policy:** retarget the narrow Ruff `S310`/`S202` suppression in + `implementations/python/pyproject.toml` to only the new OCI implementation + file. Do not broaden it to the package or remove it while the explicit URL + fetch/tar extraction remains. Preserve Hatch package discovery and the API + documentation's `raes.module_registry` path. +- **Release record:** the issue requests a `CHANGELOG.md` entry, but the + repository's authoritative `.gc/plan-rules.md` forbids hand-editing that + file or adding fragments; release-please generates it from the conventional + commit on `main`. The implementation must leave `CHANGELOG.md` untouched and + use an appropriate non-behavior-changing conventional commit/PR title (for + example `refactor:`). This is the only repository-compliant interpretation + of that acceptance item. + +## Extensibility Seam And Non-Goals + +The sole future extension seam remains the private registry-resolution policy: +source class plus SDL base directory, existing trust policy, and the private +OCI resource-limit policy. A future import source or tunable OCI limit adds to +that seam; it must not require parser/compiler/runtime/CLI-specific resolver +variants or a new lockfile schema. + +This is a pure structural refactor. It must not change import syntax, schemas, +lockfile contents/serialization, resolved-source semantics, trust defaults, +signature payloads, cache layout, OCI publishing layout, CLI behavior, +composition order, validation, runtime behavior, or pre-existing tests. Do +not modify external `raes.module_registry` import lines, use wildcard exports, +or widen the work into registry authentication, cache redesign, observability, +or the legacy namespace. diff --git a/docs/explain/reference/shared-semantic-integrity.md b/docs/explain/reference/shared-semantic-integrity.md index 0afa7b79b..9ec0e6447 100644 --- a/docs/explain/reference/shared-semantic-integrity.md +++ b/docs/explain/reference/shared-semantic-integrity.md @@ -230,7 +230,7 @@ so they are tracked by their own requirements, not here. | --- | --- | --- | --- | --- | | Fail-closed semantic validation (cross-cutting gate) | SEM-201 | validation, instantiation | `implementations/python/packages/raes/validator/__init__.py`, `implementations/python/packages/raes/instantiate.py`, `implementations/python/tests/test_sdl_validator.py` | active | | Stable identifiers, parameterized values, and qualified references | DSL-101, DSL-102, SEM-205 | authoring, validation, instantiation, compilation, planning, execution, observation | `docs/decisions/adrs/adr-076-portable-sdl-identifiers-and-canonical-addresses.md`, `specs/sdl/document-model.md`, `specs/sdl/references.md`, `implementations/python/packages/raes/_identifiers.py`, `implementations/python/packages/raes/_declarations.py`, `implementations/python/packages/raes/parser.py`, `implementations/python/packages/raes/composition.py`, `implementations/python/packages/raes_processor/compiler/__init__.py`, `implementations/python/packages/raes_runtime/backend_calls.py`, `implementations/python/packages/raes_runtime/control_plane.py`, `implementations/python/tests/test_sdl_identifiers.py` | active | -| Deterministic module composition and canonical-identity stability across expansion | DSL-103, SEM-205 | authoring, validation, compilation | `implementations/python/packages/raes/composition.py`, `implementations/python/packages/raes/module_registry.py`, `specs/formal/composition-readiness.md`, `implementations/python/tests/test_sdl_module_registry.py` | active | +| Deterministic module composition and canonical-identity stability across expansion | DSL-103, SEM-205 | authoring, validation, compilation | `implementations/python/packages/raes/composition.py`, `implementations/python/packages/raes/module_registry/__init__.py`, `specs/formal/composition-readiness.md`, `implementations/python/tests/test_sdl_module_registry.py` | active | | Instantiation, closed portable phase contracts, and revalidation of concrete scenarios | RUN-301 | instantiation, validation | `docs/decisions/adrs/adr-078-closed-sdl-phase-contracts-and-portable-derivation-evidence.md`, `specs/formal/sdl-phases/README.md`, `contracts/schemas/sdl/instantiated-scenario-v1.json`, `contracts/schemas/sdl/instantiated-scenario-snapshot-v1.json`, `implementations/python/packages/raes/phase_contracts.py`, `implementations/python/packages/raes/instantiate.py`, `implementations/python/tests/test_sdl_phase_contracts.py`, `implementations/python/tests/test_instantiated_scenario_schema.py`, `implementations/python/tests/test_sdl_validator.py`, `implementations/python/tests/test_run_300_lifecycle.py` | active | | Objective windows, referenced scopes, reachability, and refresh | SEM-202 | validation, compilation, planning | `implementations/python/packages/raes/semantics/objectives.py`, `specs/formal/objectives/README.md`, `specs/formal/objectives/window-consistency.md`, `implementations/python/tests/test_semantics_objectives.py`, `implementations/python/tests/test_fm2_semantics.py` | active | | Declarative objective actor binding, target resolution, success interpretation, and dependency ordering | DSL-112, SEM-207 | authoring, validation, instantiation, compilation, planning | `implementations/python/packages/raes/objectives.py`, `implementations/python/packages/raes/semantics/objective_semantics.py`, `implementations/python/packages/raes/validator/__init__.py`, `implementations/python/packages/raes_processor/compiler/__init__.py`, `implementations/python/packages/raes_processor/models/`, `specs/formal/objectives/README.md`, `specs/formal/objectives/declarative-objective-semantics.md`, `implementations/python/tests/test_semantics_objectives.py`, `implementations/python/tests/test_fm2_semantics.py`, `implementations/python/tests/test_sdl_validator.py` | active | diff --git a/implementations/python/packages/raes/module_registry.py b/implementations/python/packages/raes/module_registry.py deleted file mode 100644 index df245fbdd..000000000 --- a/implementations/python/packages/raes/module_registry.py +++ /dev/null @@ -1,897 +0,0 @@ -"""Registry-aware SDL module resolution and publishing.""" -

It must not rewrite the authored plan or +backend snapshot, and it must not replace model or semantic validation. +Use the repository's RFC 8785/JCS helpers in `raes_contracts.canonical` for +commitments; do not add another JSON canonicalizer or digest format. + +### Preserve the secret boundary + +ADR-056 and `raes.runtime_values.enforce_observed_value_redaction` remain the +authoring/model authority. `redacted` and `operator_secret` members must omit +raw values. Forwarding enrollment posture remains a closed classification with +no raw identity field. + +The runtime comparison projection must never place an environment or +forwarding-setting raw value in a snapshot, provenance entry, diagnostic, +audit event, log, fixture, or exception. Compare these records by stable +identity, provenance, classification, and a versioned, domain-separated +non-reversible commitment when a value is present. A backend must derive the +observed commitment from independent readback; echoing the planned commitment +is not readback evidence. + +There is no declared value from which to derive equality for an +`operator_secret` or `redacted` member. For those classifications the gate can +enforce identity, provenance, classification, omission of raw material, and +presence posture, but must not claim value equality. A stronger claim requires +a separately governed secret-binding/verifier input; it must not be simulated +by hashing an empty string or by adding a raw secret field. Deliberate +`secret_fixture` content follows its existing authoring contract, but its +snapshot comparison still uses a commitment rather than redisclosing the +value. + +The generic `SnapshotEntry.payload` contract currently accepts arbitrary +JSON-like dictionaries and the control-plane store/API copy them verbatim. +Therefore the backend-return boundary must validate the projected runtime +concern before persistence or API conversion. Authentication does not make +secret-bearing snapshot payloads acceptable. + +### Keep mounts and persistent state separate + +`persistent_volumes` is the sole portable stateful-volume desired-state +authority and already compiles to its own exact SEM-218 requirement and stable +resource address. The `runtime-mounts` concern covers non-stateful node-runtime +mount realization, specifically bind/tmpfs declarations. It must not reinterpret +`RuntimeMountSourceKind.VOLUME` as a `persistent_volume`, and it must not lower +the same `(node, target)` through both concerns. + +The existing stateful-resource consumer/destination validation in +`raes._stateful_resource_references` remains authoritative. Semantic admission +must reject an authored runtime mount whose node/target is already owned by a +generated artifact or persistent volume. Backends must not satisfy a +`persistent-volume` requirement by returning a matching runtime mount. + +### Keep adjacent meanings distinct + +- `service-listeners` means in-node bind state; it is not `Node.services` and + not host publication. +- `published-ports` means host/container exposure; it is not proof of listener + ownership or readiness. +- `forwarding-agents` means the typed source/transform/target/buffer runtime + family; it is not a generic service or relationship replacement. +- `linux-capabilities` is the authored effective/policy shape; it is not the + backend's coarse “privileged” flag. +- SEM-218 requirement kinds are distinct from + `raes_contracts.realization_envelope.RealizationConcern` observation-strength + categories. Do not merge their vocabularies or registries. + +## Canonical Incumbents + +The implementation must build on: + +- SDL shape and local validation: `raes._base.SDLModel`, + `raes.runtime_configuration`, `raes.runtime_mounts`, + `raes.runtime_capabilities`, `raes.runtime_network`, + `raes.runtime_forwarding_agent`, `raes.runtime_listeners`, and + `raes.runtime_values`; +- cross-model admission: `raes.validator.SemanticValidator`, especially + `_runtime_services`, `_runtime_platform`, `_runtime_identity_data`, and the + stateful-resource reference checks; +- author intent: `raes.explicitness`, `raes.realization_designation`, + instantiation provenance, and concrete revalidation; +- compilation: `raes_processor.compiler.realization_requirements`, + the existing node address helpers, `RuntimeModel.realization_requirements`, + and `resource_payload()`; +- admission and open envelopes: + `realization_support_diagnostics()`, + `realization_envelope_diagnostics()`, and canonical + `subsumes(offered, requested)`; +- manifest contracts: `RealizationSupportDeclaration`, + `RealizationSupportDeclarationModel`, `BackendManifestV2Model`, manifest + serializers, concept bindings, and backend manifest fixtures; +- execution and errors: `raes_runtime.backend_calls._call_backend_apply`, + `realization_disclosure()`, `Diagnostic`, `ApplyResult`, and the existing + `runtime.backend-contract-invalid` fail-closed path; +- observation and persistence: `RuntimeSnapshot`, `SnapshotEntry`, + `RealizationProvenanceEntry`, `RuntimeSnapshotEnvelopeModel`, + `_snapshot_payload()`, `_snapshot_from_payload()`, and `_snapshot_model()`; +- canonical commitments: `raes_contracts.canonical`; +- backend honesty/conformance: the existing realization-honesty and + cross-backend conformance corpus, without replacing its independent + observation-strength vocabulary; and +- repository workflow: `.ground-control.yaml`, `.gc/plan-rules.md`, + generated-schema parity, schema-publication governance, repo policy, + requirement governance, and `tools/verify_all.py`. + +## Cross-Cutting Gates + +- **Parser and closed-model gate.** Existing Pydantic fields, enum parsers, + path/port validators, profile guards, duplicate checks, and + `extra="forbid"` remain authoritative. The registry consumes validated + models; it does not parse YAML or accept free-form concern payloads. +- **Semantic validation gate.** Existing service/listener/published-port, + process, forwarding-target, and identity references must resolve before + compilation. Add only the missing runtime-mount/stateful-destination + exclusivity rule; do not duplicate local validators in the compiler. +- **Instantiation gate.** Preserve `model_fields_set`, explicitness, parameter + provenance, scoped realization designation, and concrete revalidation. Do + not infer explicitness from a serialized payload. +- **Manifest/config gate.** New kind strings flow through the existing + `supported_constraint_kinds`, exact `declared-capability-match`, + `open-realization`, disclosure-kind, concept-binding, and backend-manifest-v2 + validation surfaces. Do not add per-dimension booleans or a new manifest. +- **Envelope gate.** Open nested runtime paths use the existing + `RealizationEnvelopeModel` tokenization and subsumption relation. The + descriptor supplies the authored field path; it must not invent an envelope + dialect. +- **Backend-return gate.** `_call_backend_apply()` remains the only acceptance + point. Omission or mismatch of an exact projected concern yields the existing + sanitized `runtime.backend-contract-invalid` diagnostic and restores the + baseline snapshot. +- **Persistence/schema gate.** Accepted snapshots must round-trip through the + existing store and `RuntimeSnapshotEnvelopeModel`. If a portable commitment + carrier changes a published schema, update the hand-governed schema, + `schema_bundle()`, fixtures, publication manifest ledger, and generated + parity together. Do not use `metadata`, `details`, or a sidecar store. +- **Authentication/authorization gate.** Snapshot reads continue through + `ControlPlaneSecurityConfig`, verified identity/bearer authentication, + backend/operator/auditor role checks, target binding, request-size guards, + and audit recording. No new endpoint or unauthenticated read path is needed. +- **Error-envelope gate.** Diagnostics may name only address, authored field + path, concern kind, and the coarse mismatch/omission reason. Existing backend + exception reduction and the redacted HTTP 500 envelope remain in force; no + raw payload, value, commitment input, native exception text, or traceback may + be rendered. +- **Host/OS exposure gate.** Registry/compiler work performs no subprocess or + environment lookup. Backend follow-up must not pass environment values, + enrollment material, tokens, or mount secrets in process argv. Use the + backend's existing fixed-argv, no-shell runner and a bounded protected input + channel when materialization needs secret input. + +## Gotchas And Anti-Patterns + +Avoid: + +- adding only `CONCERN_PAYLOAD_PATH` entries and relying on raw equality; +- comparing list order instead of portable keyed/set semantics; +- hashing an entire raw record, which can preserve accidental descriptions, + evidence refs, or backend-native data as realization meaning; +- treating a plain SHA-256 of a low-entropy operator secret as a safe verifier; +- echoing plan payloads or commitments into the snapshot as “independent” + readback; +- recording commitments in `realization_provenance`, whose contract deliberately + carries no realized value; +- weakening an exact aggregate because one backend can realize only some + members; +- treating exact support for one runtime concern as support for all six; +- duplicating classifier, support, envelope, exception, persistence, logging, + or conformance workflows; +- conflating runtime listeners, host-published ports, service declarations, + readiness evidence, and realization-envelope observation categories; or +- widening stub/reference/libvirt manifests merely to keep existing scenarios + green. A backend should claim a new kind only when it can materialize and + independently observe the complete canonical projection. + +## Non-Goals And Boundaries + +- No issue implementation is performed by this preflight. +- No new SDL runtime fields, top-level sections, parser, exception hierarchy, + persistence store, API endpoint, logging stack, or backend-specific dialect. +- No readiness/health realization concern. +- No initial lowering of `identity_authorities`, `operational_policy`, other + `RuntimeConfiguration` families, or scenario-level forwarding agents. +- No redesign of `dynamic-composition`, artifact mechanisms, realization + envelopes, observation-strength conformance, or backend capability profiles. +- No claim that runtime disclosure alone proves independent observation; + backend conformance/evidence remains responsible for that stronger claim. +- No raw operator-secret equality claim without a separately governed + secret-binding/verifier contract. diff

>500-line modules into same-named packages behind API-stable re-export facades (no behavior change): - raes_runtime/control_plane_api -> _responses/_auth/_operation_routes/ _workflow_routes/_participant_routes; version seam + app factory stay in the facade so test_version_classification's distribution_version patch holds. - raes_runtime/workflow_result_contract_checks ->

The GitHub issue is the delivery contract. This note records +architecture guardrails only; it does not implement the split. + +## Current-Tree Reconciliation + +The four current targets are: + +- `raes_runtime.control_plane_api` (689 lines); +- `raes_runtime.workflow_result_contract_checks` (585 lines); +- `raes_mcp.tools.authoring` (694 lines); and +- `raes_mcp.tools.inspection` (599 lines). + +ADR-015's amended source-file cap is 500 lines. Each target must become a +same-named package, every Python file in those packages must remain at or below +that cap, and only the four corresponding entries must be drained from +`tools/policy/oversized_allowlist.yaml`. The fixed historical baseline in +`tools/policy/repo_policy.py` must remain unchanged. + +The issue asks for a `CHANGELOG.md` entry, but `.gc/plan-rules.md` and the +release workflow make release-please the sole owner of that file. The split +must leave `CHANGELOG.md` untouched and use a non-behavior-changing +Conventional Commit / PR title such as `refactor:`. + +## Package Boundaries + +### Runtime control-plane API + +Keep the facade as the application composition boundary. Cohesive internal +boundaries already exist around authentication and FastAPI dependencies, +request guards, operation routes, workflow routes, and participant route +families. Route modules may register routes against `(FastAPI, +RuntimeControlPlane)`; they must not become controllers with their own runtime +service, store, security configuration, DTOs, or audit implementation. + +The existing sibling modules remain canonical and remain at their current +stable import paths: + +- `control_plane_api_models.py` owns request DTOs, contract/model conversion, + snapshot conversion, and request fingerprints; +- `control_plane_api_guards.py` owns request-size enforcement and its 400/413 + envelopes; +- `control_plane_api_participant_retrieval.py` owns governed participant view + routes; +- `control_plane_security.py` owns identities, roles, subject bindings, and + fail-closed security defaults; +- `control_plane.py` is the service boundary; and +- `control_plane_store.py` is the persistence and append-only audit boundary. + +Do not duplicate or move these concerns into the new package. Preserve route +registration order, route function names and signatures, response models, +response-status declarations, dependency annotations, `app.state` key, +idempotency header/fingerprint flow, audit calls, and exception mappings. + +### Workflow result-contract checks + +Partition the current implementation along its existing call graph: +snapshot/context normalization, state and step checks, history checks, and +compensation checks. `_WorkflowContext` remains an internal validation carrier, +not a new contract DTO or public schema. The existing +`workflow_result_contract_context.py`, +`workflow_result_contract_compensation.py`, `raes_contracts.workflow` models, +and `diagnostics.py` helpers remain the authorities. + +Diagnostic order is behavior. Preserve the current fail-fast snapshot shape +check, workflow-result iteration order, context-normalization failure order, +and the ordered aggregation of schema, compensation requirement, step +presence, step contract, execution contract, history, and compensation-history +diagnostics. Do not replace `from_mapping()`, `from_payload()`, +`validate_workflow_step_result_contract()`, `_parse_timestamp()`, or +`_failure_diagnostic()` with local parsing or validation. + +### MCP authoring and inspection + +Keep `register(FastMCP)` as each package's sole server registration boundary, +with unchanged tool names, descriptions, signatures, defaults, registration +order, and text responses. + +Authoring remains a presentation adapter over `parse_sdl()`, +`load_sdl_fragment()`, `instantiate_scenario()`, and their existing exception +types. Scaffold templates are examples, not schemas. Inspection remains a +best-effort human-readable view: its reference map and ASCII topology are not +semantic validation, compiler, or runtime topology authorities. + +The similar section lists and input-size constants in authoring, inspection, +and `operation_support.py` do not have interchangeable output contracts. +Consolidating them could change visible sections or error envelopes and is +outside this behavior-preserving split. Do not introduce a generic MCP utility +layer or silently route these text tools through the structured operation-tool +pipeline. + +## Compatibility Guardrails + +The four source modules currently declare no `__all__`. Do not add a +restrictive `__all__` that changes star-import behavior. The package facades +must preserve at least every observed import and module-object seam: + +- `raes_runtime.control_plane_api`: `create_control_plane_app`, + `_receipt_response`, and `_control_plane_api_version`; +- `raes_runtime.workflow_result_contract_checks`: + `workflow_result_contract_diagnostics` and `_WorkflowContext`; +- `raes_mcp.tools.authoring`: `register`; and +- `raes_mcp.tools.inspection`: `register`. + +`test_version_classification.py` imports `raes_runtime.control_plane_api` as a +module and patches `distribution_version` on that package object before calling +`_control_plane_api_version()`. A simple re-export of a helper defined in a +submodule would resolve the unpatched submodule global and break this behavior. +Keep the version lookup in the facade or retain an equally narrow +facade-compatible indirection. Preserve `PackageNotFoundError` handling and the +`0.0.0+unknown` sentinel. + +`workflow_result_contract_compensation.py` imports `_WorkflowContext` from +`.workflow_result_contract_checks` under `TYPE_CHECKING`, while +`workflow_result_contracts.py` imports +`workflow_result_contract_diagnostics` from the same path. Both lines must +continue to resolve without modification or a facade/submodule cycle. + +FastAPI derives OpenAPI metadata from the decorated functions, and FastMCP +derives tool schemas from its decorated functions. Moving code must not change +function names, annotations, defaults, decorator metadata, route/tool order, or +the public module paths used by the server and Sphinx autodoc. + +## Cross-Cutting Obligations + +- **Authentication and authorization:** preserve bearer-token lookup, explicit + proxy-header opt-in, verified-identity enforcement, target binding, + read-versus-mutate role sets, governed participant audience/subject + bindings, and denial auditing. Raw bearer tokens must never enter audit + records, logs, errors, process arguments, or environment-derived fallback + configuration. +- **Input and shape validation:** preserve FastAPI/Pydantic request validation, + `extra="forbid"` request bodies, canonical `raes_contracts` response models, + request-size/content-length guards, SDL input byte limits, canonical SDL + parser and migration policy, duplicate-key-aware fragment loading, synthetic + fragment name overwrite, JSON-object parameter validation, inspection + attribute allowlisting, and recursion limits. +- **Errors and observability:** preserve exact HTTP status/detail behavior, + redacted 500 responses, `RuntimeControlPlane.record_audit()` and + `AuditEvent` persistence, MCP text error envelopes, and + `runtime.backend-contract-invalid` diagnostics. Do not add a parallel + exception hierarchy, logger, telemetry path, or error payload. +- **Secrets and data minimization:** MCP instantiation responses must remain + summaries and must not echo parameter values. The split adds no network, + filesystem, subprocess, credential, environment, or command-line surface. +- **Persistence and idempotency:** API modules call `RuntimeControlPlane`; + only the existing control-plane/store layer owns operation records, + snapshots, audit events, idempotency lookups, and atomic participant + transitions. Route code must not access a store directly. +- **Module ownership:** retain ADR-036 import directions. `raes_mcp` must not + import `raes_runtime`; `raes_runtime` must not import MCP, CLI, stub, or + conformance implementations and may consume only allowed public processor + prefixes and neutral `raes_contracts` DTOs. + +## Repository Integration Guardrails + +- Retarget the narrow Ruff `B008` override in + `implementations/python/pyproject.toml` to only the new control-plane API + file(s) that retain FastAPI `Depends()` annotations. Do not broaden the + suppression to unrelated runtime code. +- Retarget the exact + `implementations/python/packages/raes_runtime/control_plane_api.py` ownership + entry in `tools/policy/requirement_order.yaml` to the package root so future + path-prefix checks still cover its submodules. +- Update the implementation-path reference in + `docs/explain/reference/shared-semantic-integrity.md` when the package exists. + Keep the public autodoc target `raes_runtime.control_plane_api` unchanged. +- Hatch's existing package-root discovery already covers nested packages; do + not add a second distribution or entry point. `raes-mcp` continues through + `raes_mcp.server:main`, and the control-plane app remains an explicitly + constructed ASGI object rather than a new host/process binding. +- Preserve every external import line identified by the issue, including the + relative imports above. The only path-literal/configuration edits are those + needed to follow the file-to-package conversion. + +## Extensibility Seams And Non-Goals + +The existing seams are sufficient: + +- a future control-plane route family adds one registrar to the app composition + boundary while reusing the same auth, guard, DTO, audit, and service layers; +- a future workflow rule joins the existing ordered diagnostic aggregation and + consumes `_WorkflowContext`; +- a future scaffold complexity adds a template through the existing + complexity-to-template selection; and +- a future inspection tool registers through `register(FastMCP)` and reuses the + package's bounded canonical parse path. + +This issue does not change HTTP or MCP behavior, public schemas, SDL semantics, +workflow contract meaning, validation rules, route/tool inventory, security +policy, trust defaults, persistence, audit contents, idempotency semantics, +diagnostic order or wording, scaffold content, reference-map coverage, topology +rendering, packaging entry points, or existing tests. It does not reconcile +the presentation-only section catalogs, introduce shared controllers/services, +move private helpers into `raes_contracts`, or create compatibility aliases for +the retired legacy namespaces. diff --git a/docs/explain/reference/shared-semantic-integrity.md b/docs/explain/reference/shared-semantic-integrity.md index 9ec0e6447..48515be46 100644 --- a/docs/explain/reference/shared-semantic-integrity.md +++ b/docs/explain/reference/shared-semantic-integrity.md @@ -241,7 +241,7 @@ so they are tracked by their own requirements, not here. | Planner dependency, ordering, refresh, and applicability semantics | RUN-303 | planning | `implementations/python/packages/raes_processor/semantics/planner.py`, `implementations/python/packages/raes_processor/planner/__init__.py`, `specs/formal/planner/README.md`, `specs/formal/planner/dependency-ordering.md`, `implementations/python/tests/test_semantics_planner.py`, `implementations/python/tests/test_runtime_planner.py` | active | | Live execution state and lifecycle (snapshots, results, history) | RUN-304, API-402 | execution, observation | `implementations/python/packages/raes_runtime/manager.py`, `implementations/python/packages/raes_runtime/result_contracts.py`, `implementations/python/packages/raes_processor/models/`, `implementations/python/tests/test_runtime_manager.py`, `implementations/python/tests/test_runtime_models.py` | active | | Runtime result and evaluator-result contracts | ASR-503, API-402 | execution, observation | `implementations/python/packages/raes_runtime/result_contracts.py`, `specs/formal/runtime-contracts/README.md`, `specs/formal/runtime-contracts/workflow-results.md`, `specs/formal/runtime-contracts/evaluator-results.md`, `implementations/python/tests/test_runtime_contracts.py`, `implementations/python/tests/test_run_311_participant_episode_lifecycle.py` | active | -| Control-plane semantics (auth, durable state, idempotency, audit) | API-403, API-404 | execution, observation | `implementations/python/packages/raes_runtime/control_plane_api.py`, `implementations/python/packages/raes_runtime/control_plane_security.py`, `implementations/python/packages/raes_runtime/control_plane_store.py`, `implementations/python/tests/test_runtime_control_plane.py`, `implementations/python/tests/test_runtime_control_plane_api.py` | active | +| Control-plane semantics (auth, durable state, idempotency, audit) | API-403, API-404 | execution, observation | `implementations/python/packages/raes_runtime/control_plane_api/__init__.py`, `implementations/python/packages/raes_runtime/control_plane_security.py`, `implementations/python/packages/raes_runtime/control_plane_store.py`, `implementations/python/tests/test_runtime_control_plane.py`, `implementations/python/tests/test_runtime_control_plane_api.py` | active | | Backend and processor identity, capability, and compatibility manifests | API-401, API-412 | planning, execution | `implementations/python/packages/raes_processor/manifest.py`, `implementations/python/packages/raes_processor/capabilities.py`, `implementations/python/packages/raes_contracts/apparatus.py`, `implementations/python/packages/raes_contracts/manifest_authority.py`, `implementations/python/tests/test_backend_manifest.py`, `implementations/python/tests/test_processor_manifest.py` | active | | Concept authority, controlled vocabularies, reference models, and semantic profiles (meta-layer) | GOV-920 | authoring, validation, compilation, planning, execution | `specs/concept-authority/concept-authority.md`, `specs/concept-authority/semantic-profiles.md`, `implementations/python/packages/raes_contracts/semantic_profiles.py`, `implementations/python/packages/raes_contracts/controlled_vocabularies.py`, `implementations/python/packages/raes_contracts/reference_models.py`, `docs/explain/reference/shared-concept-model.md`, `implementations/python/tests/test_concept_authority.py`, `implementations/python/tests/test_semantic_profiles.py` | active | | Participant episode lifecycle boundaries (initialization, reset, completion, timeout, truncation, interruption) | RUN-311, SEM-222 | execution, observation | `docs/decisions/adrs/adr-013-participant-episode-lifecycle-boundaries.md`, `implementations/python/tests/test_run_311_participant_episode_lifecycle.py` | partial | diff --git a/implementations/python/packages/raes_mcp/tools/authoring/__init__.py b/implementations/python/packages/raes_mcp/tools/authoring/__init__.py new file mode 100644 index 000000000..9a6d4b1cc --- /dev/null +++ b/implementations/python/packages/raes_mcp/tools/authoring/__init__.py @@ -0,0 +1,19 @@ +"""SDL authoring tools — validate, scaffold, and instantiate scenarios. + +These tools let agents write SDL from scratch, check it for errors, +build up scenarios incrementally, and instantiate parameterized +scenarios with concrete values. + +This package is a thin facade over cohesive subdomains: + +* :mod:`.tools` -

Extract cohesive helpers and add type hints, preserving every MCP tool name, description, signature, and output string (behavior verified by test_mcp_server.py).

+Requirement: none. The GitHub issue title, body, acceptance criteria, and +non-goals are the authoritative contract. + +This note records architecture guardrails for a typed, scheme-neutral external +concept-binding surface. It is guidance only: it does not add or change +contracts, schemas, validators, SDL behavior, fixtures, persistence, or an +implementation plan. + +## Existing Authorities And The Boundary They Establish + +- ADR-012 and ADR-062, `specs/concept-authority/`, and + `contracts/concept-authority/` already own concept authority, provenance + classification, controlled vocabularies, catalogs, and offline governance. + A portable external binding must compose with those authorities rather than + create another concept-family catalog or global ontology registry. +- Apparatus-manifest `ConceptBinding` binds a governed manifest vocabulary + scope to a native RAES concept family. It is not a general external + term-mapping assertion. Expanding that model would conflate manifest + vocabulary governance with author-authored claims about arbitrary exact RAES + subjects. +- SEM-217 and `semantic_binding_effects.py` already distinguish the external + knowledge effects `annotates`, `aligns`, `refines`, and `constrains`. These + terms do not by themselves alter schemas, runtime behavior, or admission. + Issue #986 must reuse that meaning and must not publish a second effect + vocabulary with subtly different semantics. +- The ATT&CK, ATLAS, and NIST CSF source contracts in + `contracts/concept-authority/` are offline, versioned authority snapshots, + but their current Python models are source-shaped. They are useful resolver + inputs and fixtures, not the author-facing portable assertion shape. +- ADR-076 and `raes._declarations.DeclarationIndex` own exact SDL authoring + identities and collision-preserving address resolution. Processor/runtime + `CompiledAddress`, JSON Pointer, collection position, aliases, and prose + names are not substitutes for canonical authoring identity. +- ADR-078, `raes.phase_contracts`, and the canonical digest helpers distinguish + normalized authoring, expanded, instantiated, and snapshot subjects. A + reference valid in one lifecycle phase is not silently valid in another. +- ADR-079 separates propositions, assertions, probe bindings, truth results, + and outcomes. An external concept binding is none of those and cannot prove + objective satisfaction. +- ADR-070 owns realization envelopes and capability boundaries. An external + binding cannot grant a capability, make a subject realizable, or transform a + value into a realizable form. +- ADR-064 and the experiment evidence contracts separate capture + specifications, evidence records, and derived measures. A binding may cite + evidence; it is not itself evidence or proof. +- ADR-066 and ADR-085 separate evidence, view, authorization, availability, + delivery, redaction, declassification, and disclosure. Listing participants + on a binding is not permission to disclose it and is not evidence that it + was delivered. +- `ContractModel`, the shared strict types, `Diagnostic`/`DiagnosticModel`, + conformance registries, schema publication records, generated-schema parity, + and fixture tooling already own the cross-cutting contract lifecycle. + +These decisions are sufficient for issue #986. A new ADR is not warranted +unless implementation proposes to alter SDL phase transitions, make external +bindings executable or validation-authoritative, add a network/global scheme +registry, or change realization, evidence, or participant-disclosure +boundaries. + +## Architecture Decisions And Guardrails + +### Publish one standalone authored assertion family + +Publish one versioned, closed root contract family, provisionally identified as +`external-concept-bindings-v1`, with a stable binding-set identity and +individually stable binding identities. Its assertion value model may be reused +by other carriers, but there must be one canonical schema and one semantic +admission path. + +The first contract should remain a standalone authored artifact. Embedding the +binding collection into every SDL phase would: + +- make an artifact-digest subject reference self-referential; +- require propagation and transformation rules across every ADR-078 phase; +- make annotations part of SDL structure without adding semantic authority; + and +- encourage compilers and runtimes to treat presence as behavior. + +Other artifacts may refer to the standalone binding set by exact +id/version/digest. Adding a top-level SDL section or copying bindings into +compiled/runtime artifacts requires a separate phase-boundary decision. + +The contract is closed. It must not contain an unconstrained metadata, +extensions, attributes, annotations, context, or arbitrary JSON object field. +Future portable dimensions belong in a versioned contract revision or a +governed extension vocabulary. + +### Identify the RAES subject exactly and phase-correctly + +The subject coordinate must make these independent: + +- subject kind; +- owning contract or surface identity and version; +- lifecycle phase; +- exact stable canonical reference; and +- the owning artifact's canonical digest where that subject kind and phase + admit one. + +Subject resolution is exact and collision preserving. For SDL declarations, +reuse `DeclarationIndex` semantics: resolve the canonical authoring address, +preserve all alias collisions, and require exactly one result. Do not import +the private SDL index into `raes_contracts`; keep resolution behind the owning +SDL boundary or extract only a dependency-neutral collision helper if it has +more than one real caller. + +A data-driven rule keyed by `(subject kind, contract/surface, lifecycle phase)` +must select the canonical reference grammar and whether a digest is required. +That is the extensibility seam for another RAES subject kind. It must not be a +chain of scheme-specific or artifact-specific conditionals inside the binding +model. + +`ValidationSubjectReferenceModel`, +`ParticipantCrossingSubjectReferenceModel`, and `ExperimentReferenceModel` +demonstrate useful exact-coordinate patterns, but each has a narrower semantic +owner. Do not broaden or union them into a falsely universal subject type. + +Aliases, prose labels, JSON Pointer, array position, filesystem paths, and +processor/runtime compiled addresses may be displayed as non-authoritative +context only. They never establish identity or break a tie. + +### Keep the scheme coordinate portable and inert + +The external coordinate must independently identify: + +- scheme id and naming authority; +- exact scheme revision; +- source locator or prefixed source-content digest, with both retained when + supplied; and +- exact concept identifier in that revision. + +Scheme id, authority, revision, locator, digest, and concept id are data. No +scheme name may select a Python class, parser, validator, URL template, import +path, plugin, command, or network client. + +A source locator is an inert identifier, not permission to dereference. +Reuse or extract the existing associated-artifact URI safety rules: require an +absolute URI and reject user information and secret-bearing query fields. The +scheme-source profile must additionally reject host-local paths, `file:` and +inline `data:` locators, and fragments, because the concept id is already a +separate field and fragments would create a second opaque identifier channel. +Never place a locator in a subprocess argument. +A content digest uses the existing prefixed-digest type and canonical +digest/checksum rules; it must not introduce another bare-hash format. + +Use one dependency-neutral local scheme-snapshot descriptor as contextual +resolver input. It carries the asserted scheme coordinate, canonical concept +membership, and bounded deprecation/supersession facts. Existing ATT&CK and +NIST CSF snapshots must adapt to that same input and pass through the same +resolver and diagnostics. Adapters translate existing source artifacts; they +must not make the portable contract a universal scheme schema. + +### Separate assertion dimensions instead of recreating a mapping string + +Every binding must keep these semantically distinct: + +- relationship kind; +- author motivation and its basis; +- claimed semantic effect; +- asserting perspective or party and the basis of its authority; +- participant availability intent, when present; +- assertion provenance; +- supporting evidence references; +- confidence posture and basis; +- approximation or semantic loss; +- limitations; and +- review status and review references. + +Use closed or governed vocabularies from +`controlled-vocabularies-v1.json` wherever portable comparison matters. +`annotates`, `aligns`, `refines`, and `constrains` retain the SEM-217 meanings. +If Python enums remain convenient, they must be derived from or parity-tested +against the catalog; source code and the catalog cannot both be independent +authorities. + +Free prose may explain motivation, limitations, or review reasoning, but prose +does not replace required typed fields. Relationship is not effect, motivation +is not confidence, scheme authority is not assertion authority, review status +is not resolution status, and assertion provenance is not evidence. + +Claims with stronger meaning require stronger explicit support: + +- equivalence/alignment claims need an explicit loss posture and review basis; +- refinement or approximation must disclose divergence or loss; +- confidence requires its basis; a numeric score additionally requires a + named calibration/profile rather than an unexplained probability; and +- `constrains` has no validation effect unless it resolves to an already + governed RAES profile or validator that independently owns that authority. + +### Resolve locally with two distinct admission levels + +Structural parsing/admission validates the closed artifact shape, field +formats, conditional presence, vocabulary membership, URI safety, and internal +identity uniqueness. It performs no lookup and therefore remains available for +offline parse, replay, and inspection. + +Contextual semantic admission is a pure operation over explicitly supplied +local inputs: + +- the exact RAES subject index for the declared contract and phase; and +- zero or more pinned scheme-snapshot descriptors. + +It must not consult the network, environment, filesystem search paths, process +state, a mutable singleton registry, or “latest” scheme state. + +Resolution has deterministic outcomes: + +| Outcome | Required behavior | +| --- | --- | +| Resolved/current | Exactly one subject and one concept match all asserted identities, revision, locator/digest constraints, and policy gates. Only then may the declared effect be considered by an existing governed consumer. | +| Unavailable | No matching local scheme snapshot was supplied. Preserve the assertion as parseable and inspectable, mark it inactive, emit a stable bounded diagnostic, and do not fetch or infer. | +| Stale | A scheme identity is present but its revision or digest conflicts with the assertion or required profile. Fail current semantic admission; never fall back to “latest”. | +| Ambiguous | More than one subject, alias, scheme, or concept candidate matches. Fail semantic admission without first/last/set-collapse behavior. | +| Superseded | Preserve the original concept and revision plus separately supplied successor facts. Never rewrite automatically. Historical replay may resolve only against the exact original snapshot; current admission requires an explicit governed policy for superseded terms. | + +An unknown concept in an available matching revision also fails semantic +admission. The resolver computes resolution state; an author cannot assert a +trusted `resolved` value. + +Negative fixtures for stale, ambiguous, unknown-relation, missing-provenance, +and impermissible-disclosure cases must exercise the same public contract and +semantic admission functions as positive fixtures. “Unavailable is +inspectable” does not mean “unavailable has semantic force.” + +### Participant availability is not disclosure authority + +A participant scope on a binding expresses intended eligibility or +availability only. If a carrier claims actual availability, exposure, or +delivery, contextual admission must join it to the existing deny-first +participant information-flow authority, including the exact participant, +episode/snapshot, subject, exposure/crossing policy, and applicable +authorization. + +Reuse `ParticipantDecisionSurfaceExposureBindingModel` and +`ParticipantCrossingOccurrenceModel` where those facts are claimed. Do not add +a binding-specific access-control list, audience gateway, declassification +mechanism, policy engine, audit store, or disclosure log. A participant id on +the assertion never bypasses redaction, information-flow control, control-plane +audience binding, or ordinary admission. + +### Preserve adjacent semantic boundaries + +- Native apparatus `ConceptBinding` continues to bind manifest vocabulary + scopes to RAES concept families. The new assertion references exact RAES + subjects and external concepts; neither replaces the other. +- A portable external binding does not create a proposition, truth result, + objective outcome, score, or behavioral claim. +- It does not alter a realization envelope, grant a capability, authorize an + action, mutate the transition system, or establish realization. +- Supporting evidence fields are typed references to existing evidence or + associated-artifact contracts. Do not copy evidence payloads into the + binding or treat citation as verification. +- The assertion itself is not a concept-family declaration, scheme snapshot, + validation profile, participant exposure, provenance proof, or review + decision. + +## Required Cross-Cutting Reuse + +| Concern | Canonical incumbent and required use | +| --- | --- | +| Concept authority | ADR-012, ADR-062, `specs/concept-authority/`, concept-family and controlled-vocabulary catalogs, and SEM-217 effect semantics. Extend governed terms once; do not add parallel registries or enums. | +| Exact subject identity | ADR-076, `DeclarationIndex`, owning-contract identity rules, and collision-preserving exact resolution. Keep authoring and compiled addresses distinct. | +| Lifecycle and digest | ADR-078, `raes.phase_contracts`, `canonical_sdl_digest()`, `canonical_instantiated_sdl_digest()`, and `canonical_contract_digest()`. Reuse RFC 8785/JCS plus SHA-256, extracting a dependency-neutral public helper if the current module ownership would otherwise create a conceptually wrong import; do not add binding-local JSON canonicalization. | +| Contract shape | `ContractModel(extra="forbid")`, `NonEmptyString`, `PrefixedDigestString`, RFC 3339 time, closed-unit-interval, and existing strict/discriminated value patterns. Add explicit validators where Pydantic coercion would weaken a semantic invariant. | +| URI safety | The associated-artifact absolute-URI and secret-bearing component checks. Extract a public dependency-neutral helper if reuse would otherwise require importing a private validator. | +| Schema authority | Hand-governed `contracts/schemas/`, Python `schema_bundle()` parity, and a sharded `contracts/schema-publication/entries/` record with `last_change` and content hash for each published schema change. | +| Validation | Existing model validators, controlled-vocabulary helpers, owning subject resolvers, `SemanticValidator` where SDL context is required, and the `raes_conformance` structural/semantic registries. There is one public validation path, not fixture-only logic. | +| Diagnostics | `Diagnostic`/`DiagnosticModel`, bounded SDL model diagnostics, and conformance `sanitized_failure_message()`. Emit stable codes and safe coordinates without Pydantic input echo or exception-string leakage. | +| Evidence | ADR-064/066 and `ExperimentEvidenceRecordModel` plus existing typed evidence/artifact references. Preserve evidence, measure, view, and assertion boundaries. | +| Participant flow | ADR-085 and the existing exposure/crossing/control-plane identity and policy contracts. Deny first and join exact context before claiming delivery. | +| Publication and tests | Existing public export/facade checks, JSON artifact checker, schema generator parity, conformance registry, and positive/negative fixture runner. ATT&CK and NIST CSF use identical syntax and validation code. | +| Persistence | Existing versioned contract artifacts and id/version/digest references. No new database, repository, cache, metadata side channel, or runtime snapshot stuffing is justified. | + +## Cross-Cutting Security And Runtime Layers + +The intended standalone contract passes through these layers: + +1. **Shape and parser boundary.** `ContractModel`, strict shared types, + conditional model validation, catalog validation, and schema validation + reject extra fields, invalid digests, unsafe locators, missing provenance, + unknown relationship/effect terms, and structurally invalid participant + scopes. Models must not fetch or instantiate caller-selected code. +2. **Subject and scheme semantic boundary.** Owning subject resolvers and the + pure local scheme resolver require exact, unique, phase-correct, + digest/revision-matching context. Unavailable, stale, ambiguous, and + superseded states cannot silently acquire semantic effect. +3. **Authorization and disclosure boundary.** Assertion authorship or an + `authority` string is descriptive provenance, not authenticated identity. + Any actual participant availability/delivery passes ADR-085's existing + identity, audience, policy, exposure/crossing, redaction, and admission + checks. No new auth surface is introduced by the artifact. +4. **Secret-handling boundary.** The contract contains no credentials, tokens, + secret values, secret-reference resolution, environment-variable names, or + credential-bearing URI components. Scheme locators and evidence references + are inert. Existing secret providers and runtime authorization remain + entirely outside this contract. +5. **Configuration/environment boundary.** Resolution context is an explicit + typed argument pinned by id/revision/digest. No environment binding, + configuration key, hidden default registry, plugin discovery, or mutable + global selects a scheme, revision, subject, or semantic effect. +6. **OS and network boundary.** Parse, admit, replay, and inspect perform no + live network lookup, subprocess execution, shell interpolation, command + dispatch, or host-path access. Locators, concept ids, and authority strings + never enter process argv. +7. **Diagnostics, error-envelope, and logging boundary.** Public failures use + stable diagnostic codes, bounded locations, and sanitized messages. Logs may + contain a safe binding id, scheme id/revision, subject kind/canonical ref + when its classification permits, digest, counts, and outcome. They must not + contain source bodies, credentials, query strings, environment dumps, + rejected attacker-controlled values, Pydantic `input_value`, raw exception + text, or tracebacks in public envelopes. +8. **Persistence and audit boundary.** Artifacts remain ordinary versioned + contract documents. Do not place bindings or raw assertion fields into + generic `metadata`, `details`, logs, audit-event payloads, or runtime + snapshot metadata. Existing provenance, evidence, and audit records may + reference a binding by exact identity and digest. + +The initial artifact introduces no controller, service, API, authenticated +mutation, or OS integration. If an API later accepts or publishes these +artifacts, it must reuse `ControlPlaneSecurityConfig.strict_defaults()`, +verified identity, audience/target binding, role checks, request-size guards, +idempotency/fingerprints, `AuditEvent`, and the existing redacted internal-error +envelope. Those are mandatory incumbents, not reasons to add issue-specific +auth or exception hierarchies. + +## Extensibility Seam + +The deliberate seam is explicit resolver context, not a global scheme +registry: + +- a subject-kind rule selects the owning reference grammar, phase, resolver, + and digest requirement; +- a scheme snapshot adapter supplies the neutral pinned descriptor and concept + membership; and +- a governed consumer decides whether a successfully resolved declared effect + is relevant to its already-authorized operation. + +A third unrelated versioned scheme should require a new snapshot adapter/data +artifact only. A new RAES subject kind should require one owner rule and +resolver only. Neither change should edit the assertion schema, add a +scheme-name branch, relax exact identity, or change offline failure behavior. + +## Gotchas And Anti-Patterns + +- Do not extend apparatus `ConceptBinding`, `BehavioralClaimBindingModel`, a + validation subject, an experiment reference, or a participant-crossing + subject until it appears generic. Their names overlap; their authorities do + not. +- Do not migrate every existing CWE, ATT&CK, ATLAS, NIST, or free-label field + in this issue. Existing source-shaped fields are compatibility surfaces, not + templates for the new contract. +- Do not publish one opaque `mapping`, `relation`, or metadata string that + collapses relationship, motivation, effect, confidence, provenance, review, + or loss. +- Do not use names, labels, aliases, JSON Pointer, list order, case folding, + first/last match, or set/map deduplication to resolve a subject or concept. +- Do not select “latest”, auto-upgrade a revision, auto-follow a successor, + accept a digest mismatch, or let unavailable data degrade to a warning while + retaining semantic effect. +- Do not make a URL required for offline validity, dereference a URL during + validation, or hide network/cache access behind a validator. +- Do not let an author-declared effect install a validator, constrain SDL, + rewrite propositions, alter outcomes, grant capability, establish + realization, or bypass ordinary admission. +- Do not interpret participant scope as an ACL or delivery record. +- Do not create a second schema source, digest profile, controlled-vocabulary + registry, fixture runner, semantic-effect enum authority, diagnostic class, + exception hierarchy, repository, cache, audit store, or disclosure workflow. +- Do not log or echo whole rejected documents. External identifiers, locators, + motivations, limitations, and evidence references are attacker-controlled + until admitted. + +## Non-Goals And Implementation Boundary + +Issue #986 does not: + +- select or mandate an external knowledge ecosystem; +- define a universal ontology or portable source format for schemes, + participants, environments, evidence, or provenance; +- turn external concepts into SDL syntax or executable constructs; +- redesign native concept families or apparatus `ConceptBinding`; +- redesign propositions, outcomes, realization envelopes, evidence records, + participant information-flow control, or admission; +- add live lookup, scheme synchronization, successor discovery, a global + registry, a cache, a database, an API, or a new control plane; +- migrate all existing source-specific fields; +- add an unconstrained metadata bag; or +- make assertions true, reviewed, disclosed, or operational merely because + they parse. diff --git a/docs/explain/reference/shared-concept-model.md b/docs/explain/reference/shared-concept-model.md index 2963a840f..aacb29aab 100644 --- a/docs/explain/reference/shared-concept-model.md +++ b/docs/explain/reference/shared-concept-model.md @@ -202,6 +202,27 @@ Implementation guidance: - do not overload `ConceptBinding` into a general external term-mapping model; it remains the manifest vocabulary-to-family binding surface. +### Portable External Concept Assertions + +The standalone `external-concept-bindings/v1` contract covers the different +case where an author or reviewer relates one exact, digest-pinned RAES subject +to a concept in an arbitrary versioned external scheme.

A scheme is identified by data, not by a +schema discriminator or an authority-specific field. Adding a scheme therefore +does not change this contract. + +An external concept binding is an authored assertion about native RAES +meaning. It is not an executable SDL construct and does not acquire authority +merely because an external scheme is named. + +## Published Contract + +The normative JSON Schema is: + +`contracts/schemas/concept-authority/external-concept-bindings-v1.json` + +A document has a stable `binding_set_id`, an authored +`binding_set_version`, and a non-empty map of assertions. Every map key must +equal the assertion's `binding_id`. Two assertions with different ids must not +duplicate the same semantic identity. + +## Exact RAES Subject Coordinate + +Every assertion identifies its RAES subject with all of: + +- `subject_kind`; +- `owning_contract_id`; +- `lifecycle_phase`; +- `canonical_ref`; and +- `artifact_digest`. + +The coordinate is resolved as one unit. A prose name, alias, suffix, compiled +address, or matching reference with a different digest is not a substitute. +SDL authoring and instantiated subjects use canonical declaration addresses +from the collision-preserving declaration index and the canonical digest for +their lifecycle phase. + +The lifecycle phase is explicit because a normalized authoring declaration, +an expanded declaration, an instantiated declaration, a compiled object, and +a realized or observed object are not interchangeable subjects. + +## External Scheme Coordinate + +Every assertion identifies the external concept independently with: + +- `scheme_id`; +- `authority`; +- `revision`; +- `concept_id`; and +- at least one of `source_locator` or `source_digest`. + +When both source fields are present, both participate in exact resolution. +Locators are inert identifiers. They must be absolute and credential-free, +must not use `file:` or `data:`, and must not contain fragments or +secret-bearing query parameters. Parsing and admission never dereference a +locator. + +## Assertion Dimensions + +The contract keeps the following dimensions separate: + +- `assertion.relationship_kind` describes the direction from the RAES subject + to the external concept; +- `assertion.motivation` and `motivation_basis_refs` explain why the assertion + was authored; +- `assertion.semantic_effect` and `semantic_effect_basis_refs` state the + claimed SEM-217 effect; +- `perspective` identifies the asserting party, its stated perspective, and + its authority basis; +- `provenance` records when the assertion was made and the typed sources on + which it depends; +- `supporting_evidence_refs` point to typed evidence or evidence-record + identities without embedding evidence; +- `confidence` records a qualitative posture and basis, with a numeric score + permitted only when a calibration profile is also referenced; +- `approximation` declares exactness, approximation, or loss, and requires + explicit loss details whenever meaning is not exact; +- `limitations` bound every assertion; and +- `review` records its review lifecycle independently of confidence. + +These fields must not be collapsed into a mapping string or an unconstrained +metadata object. + +### Relationship Kinds + +The closed relationship vocabulary is: + +- `equivalent-to`; +- `broader-than`; +- `narrower-than`; +- `related-to`; and +- `instance-of`. + +The direction is always RAES subject to external concept. + +### Semantic Effects + +The `semantic_effect` field reuses the closed SEM-217 vocabulary: +`annotates`, `constrains`, `refines`, and `aligns`. + +An effect is a claim by the asserting perspective. `annotates` does not alter +native meaning. `constrains` has enforceable effect only when an independently +governed RAES validator or profile already owns that constraint. `refines` and +`aligns` require the stated basis, approximation posture, limitations, and +review; they do not make the external scheme authoritative over RAES by +themselves. + +## Participant Availability + +Participant scope is optional and has one permitted posture: +`eligibility-only`. + +It records that named participants are intended to be eligible for the +assertion, together with typed basis references. It does not assert that the +binding or external source was disclosed, delivered, observed, or understood. +Actual availability remains governed by the existing information-flow, +participant-view, admission, and delivery contracts. Values such as +`delivered`, `visible`, or `disclosed` are invalid on this surface. + +## Offline Semantic Admission + +Structural validation is independent of contextual resolution. A structurally +valid assertion remains parseable when its external scheme is unavailable, but +it is inactive until resolved against explicit local inputs. + +The canonical conformance registry admits the document structurally through +`external-concept-bindings-v1` and reports +`conformance.semantic-context-required` when the generic fixture boundary has +not been supplied the exact subjects and pinned snapshots needed below. This +prevents the model and resolver from becoming a parallel validation path. +The normative schema expresses local conditions with Draft 2020-12 keywords +and publishes cross-entry identity conditions through the required +`x-raes-invariants` semantic profile. + +Semantic admission accepts only: + +1. a structurally admitted binding document; +2. an explicit local collection of exact RAES subject coordinates; and +3. explicit local, digest-pinned scheme snapshots. + +It must not perform network access, environment lookup, filesystem search, +subprocess execution, latest-version fallback, or mutable global-registry +lookup. + +Resolution is deterministic: + +| Outcome | Condition | Admission effect | +|---|---|---| +| `resolved-current` | Exactly one subject and one exact scheme snapshot resolve to a current concept. | Assertion is active. | +| `unavailable` | No local snapshot has the asserted scheme identity and authority. | Assertion remains parseable but inactive. | +| `stale` | The subject digest or scheme revision, locator, or digest conflicts with supplied local context. | Fail admission. | +| `ambiguous` | An exact subject or scheme coordinate resolves more than once. | Fail admission without choosing a candidate. | +| `superseded` | The exact concept is marked superseded in the pinned snapshot. | Preserve the original id; fail admission without successor rewriting. | +| `unknown-concept` | The exact pinned snapshot does not contain the concept id. | Fail admission. | +| `subject-not-found` | The exact RAES coordinate is absent from the supplied subject index. | Fail admission. | + +Diagnostics are bounded and must not echo attacker-controlled concept +identifiers. + +## Relationship to Other RAES Surfaces + +### Native `ConceptBinding` + +Manifest `ConceptBinding` maps a governed manifest vocabulary scope to a native +RAES concept family. It remains required for its owned processor, backend, and +participant-manifest surfaces. + +`external-concept-bindings/v1` is a separate assertion contract for an exact +artifact subject and an arbitrary external concept. It complements, but does +not widen or replace, native `ConceptBinding`. + +### Propositions and Outcomes + +A binding is neither a proposition nor an outcome assertion. It does not make +a proposition true, satisfy a success criterion, establish a behavioral +relation, or record an observed result. Those claims continue to use their +owned proposition, outcome, observation, and truth-result contracts. + +### Realization Envelopes + +A binding does not request, authorize, prove, or change realization. It cannot +grant processor, backend, or participant capabilities; change the transition +system; bypass admission; or modify a realization envelope. A realized or +observed object may be an exact subject only when its owning contract and +lifecycle-specific digest coordinate are independently available. + +### Evidence Records + +Typed evidence references support review of an assertion, but the binding is +not an evidence record and does not prove that referenced evidence exists, +was captured, or satisfies an experiment requirement. Evidence identity, +capture, integrity, access, and interpretation remain governed by the existing +evidence contracts. + +## Scheme Adapters + +Authority-specific source artifacts may be adapted into the neutral local +snapshot model. ATT&CK Enterprise tactics and NIST CSF defensive categories +are the initial unrelated examples. Both use the same authored syntax, schema, +subject resolution, and offline admission path. + +An adapter projects a pinned source artifact into scheme identity, authority, +revision, locator, digest, and a multiplicity-preserving concept candidate +list. Candidate ids are not converted into dictionary keys: zero matches are +unknown, one match resolves, and multiple matches are ambiguous. An adapter +does not add branches to the portable authored contract or fetch an authority +at admission time. diff --git a/tools/generate_contract_schemas.py b/tools/generate_contract_schemas.py index

+ +Issue: #961. + +Requirements: `SEM-231`, `ASR-535`. + +This note records architecture guardrails for the first executable +participant-opacity assurance lane. It is guidance only. It does not publish a +profile or schema, implement a checker, execute a finite model, change catalog +assurance, establish opacity, activate `SEM-231`, or make a model-check, proof, +runtime-enforcement, backend-realization, or backend-conformance claim. + +## Decisive Current-State Finding + +Issue #961 must complete an existing shared seam, not create an opacity +subsystem. + +- ADR-099 and the SEM-231 formal authority already define + `participant-predicate-opacity`, its possible-point and information-cell + semantics, active-strategy quantifier, supervisor visibility, release, + memory, and relation boundaries. +- The behavioral catalog advanced to `raes-behavioral-relations@rev7` with + this bounded-checker delivery and remains the + only relation registry. `BehavioralClaimBindingModel` already carries a + relation-profile ref/revision and assurance axis. +- `validate_behavioral_claim_binding()` currently checks that a required + profile coordinate is present, but it does not resolve that coordinate to a + governed profile or validate relation/profile/projection identity. That is + the contract gap #961 must close. +- `raes_processor.satisfiability` and `raes_processor.exploit_path` already own + the repository pattern for side-effect-free finite analysis: closed + normalized inputs and evidence in `raes_contracts`, deterministic + translation/admission/checking and replay in `raes_processor`, typed + unsupported outcomes, digest joins, and value-free operational errors. +- `raes_conformance.behavioral_validation` remains the subject/backend + execution-probe seam. Its trusted-executor, cleanup, and live-execution + abstractions are useful discipline, but they are not the semantic carrier + for an exhaustive pure opacity check. +- ASR-535 participant-policy probes, `BackendConformanceReport`, RUN-319, and + API-407 concern runtime or backend behavior. A pure finite possible-point + check does not pass those boundaries and must not be reported through them. + +The smallest coherent addition is one shared, resolved behavioral-relation +profile contract, one normalized finite opacity input/evidence contract, and +one relation-specific processor analysis service. No new ADR, relation +registry, policy engine, runtime store, backend profile, conformance report, +exception hierarchy, logger, endpoint, or workflow is justified. + +## Architecture Decisions And Guardrails + +### Publish one shared relation-profile contract + +The profile authority belongs under the existing normative `contracts/profiles` +family and the owning model/loader belongs in `raes_contracts`. Use a common +behavioral-relation profile header with a closed, discriminated +relation-specific parameter payload. The first payload variant is +`participant-predicate-opacity`; the next relation, including the +participant-bisimulation work, extends that same discriminated seam rather than +creating another registry. + +The common header must bind: + +- schema version, profile id, profile revision, relation id, and exact + behavioral taxonomy coordinates; +- the observation projection ref/revision used by the claim; +- the possible-point carrier kind and finite analysis scope; +- limitations and explicit nonclaims; and +- any safe immutable source refs/digests needed to reproduce profile meaning. + +The opacity payload must close, with typed fields or revisioned refs: + +- individual observer or coalition, audience, and coalition fusion rule; +- secret-predicate identity/revision and one-sided truth polarity; +- possible-point and reachability carrier; +- initial-information and accumulated-observation functions; +- cut/horizon and retained-memory/reset behavior; +- passive or finite active-strategy domain; +- supervisor visibility and decision-observation posture; +- exact-cut policy and declassification/release schedule; +- scheduler and environment domains; +- nondeterminism support; +- order, concurrency, and partial-order treatment; +- time, progress, opportunity/deadline, and absence treatment; and +- the baseline exclusion of probability measures and quantitative leakage. + +Do not encode those coordinates in an open `dict`, an executable expression, +SDL metadata, `subject`, `evidence_boundary`, `limitations`, an opacity-local +enum registry, or a copy of `ParticipantPolicyBinding`. Complex functions are +revisioned references implemented by trusted code or materialized into a +finite model; profile JSON is never an import path, Python expression, remote +URL, or policy program. + +Profile identity is exact. A claim's profile ref and revision must resolve to +one artifact whose relation, taxonomy, and observation-projection coordinates +match the claim. There is no `latest` alias, version range, fallback profile, +or consumer-selected partial default. + +### Keep profile validation and claim validation as one join + +`validate_behavioral_claim_binding()` remains the canonical semantic join. Its +profile-aware path must: + +- resolve the profile through the shared canonical loader; +- require ref/id and requested/artifact revision equality; +- require relation id and taxonomy coordinates to agree across catalog, + profile, and claim; +- require the claim projection pair to equal the profile projection pair; and +- retain the existing quantifier/evidence/assurance-axis checks. + +The loader must follow the hardened corpus precedents: validate profile-id +grammar before path construction, resolve through +`corpus_family_root(PROFILES)`, use bounded duplicate-rejecting JSON ingress, +validate a closed `ContractModel`, assert artifact/request identity, and work +identically from a source checkout and packaged corpus. Tests may inject an +explicit trusted profile/catalog object; production validation must not accept +an arbitrary root from the claim. + +Cross-reference rules belong in this one semantic validator. Pydantic shape +validators enforce local invariants; conformance, studies, completeness +profiles, policy scripts, and future model checking must not each reimplement +relation/profile resolution. + +### Decide only a declared finite possible-point model + +The #961 evaluator is a deterministic finite falsifier for the SEM-231 kernel: +for each reachable secret point in the admitted finite carrier, it seeks a +reachable nonsecret point in the same declared information cell. It is not a +runtime monitor and it does not explore an implicit transition system. + +Its admitted input must be typed and digest-bound and must declare exact finite +bounds and realized counts for points, states/runs or run refs, cuts, +strategies, schedulers/environments, and order variants used by the profile. +Every point and reference must resolve inside that input. A missing coordinate, +unresolved ref, duplicate id, or digest/count mismatch is rejected at +admission. A valid shape with an unsupported dimension, exceeded deterministic +resource bound, truncated enumeration, or timeout produces a typed unsupported +or operational failure according to the incumbent analyzer boundary; it never +becomes a passing opacity result or durable partial evidence. + +Information-cell equality is derived from the profile's initial-information, +observation, memory, coalition, strategy, release, and order coordinates. It +must not be reduced to payload equality or a caller-supplied `same_cell` +boolean. For an active profile, the actual and alternative point use the same +strategy, and all declared finite strategies are checked. For a coalition, +the checker uses the declared fused member observations and memories, not a +representative individual. + +Absence is observable only when the profile supplies an opportunity, +deadline, acknowledgement, clock, or progress basis. Declassification may +split a cell and change knowledge; later concealment, revocation, reset, +rollback, or supersession does not remove retained observations unless the +profile contains a trusted memory-reset rule. + +A finite carrier with no reachable protected secret point must not be reported +as positive assurance. It is vacuous or inapplicable evidence and needs an +explicit non-passing disposition. Empty or unreachable cells likewise do not +establish opacity. + +### Keep the normalized finite input separate from the profile + +The profile selects semantics and bounds; it is not a container for one +fixture's possible worlds. A separate closed normalized input represents the +exact finite points admitted under that profile. It may carry only +checker-relevant abstract coordinates: stable safe point/run/strategy refs, +reachability, secret truth labels, initial-information and observation keys, +cut/release/memory coordinates, declared bounds, and exact +source/profile/materializer digests. + +The normalized input is a finite projection of the incumbent SEM-230, +participant-view, decision, crossing, delivery, observation, policy-cut, +scheduler, environment, order, and memory carriers. It is not a new +world-state or participant-history model. A trusted materializer constructs +it; the opacity evaluator does not accept raw runtime/backend objects or +invent a second projection policy. + +`raes_contracts.bounded_domains` may supply exact, enum, Boolean, +governed-reference, and closed-record value shapes. A +`NumericIntervalDomain` is not by itself enumerable: any numeric range in an +exhaustive profile needs a finite enumeration or a bounded step/cardinality +whose expansion is itself validated and digest-bound. + +### Use the processor analysis/evidence/replay pattern + +Portable profile, normalized-input, checker-configuration, outcome, and +evidence DTOs belong in `raes_contracts`. Deterministic preflight, evaluation, +canonical counterexample selection, and replay belong in a narrow public +`raes_processor` analysis package, following satisfiability and exploit-path +analysis. The checker is in-process, read-only, and side-effect free. + +Reuse the claim-admission, canonical-digest, stable-diagnostic, typed +unsupported, deterministic ordering, and fail-closed disciplines from +behavioral validation and existing processor analyzers. Do not wrap the pure +algorithm in `BehavioralProbeCase`, fake a participant subject or live +execution basis, fork the generic behavioral-probe runner, or project the +result into `BackendConformanceReport`. + +The harness supplies only admitted finite inputs and expected fixtures. The +production evaluator derives information cells, checks every admitted point, +and owns the verdict. Counterexample choice follows a declared canonical order +so input permutation and Python hash order cannot change result identity. + +### Bind results to exact evidence and an honest claim + +Follow `ScenarioSatisfiabilityEvidenceModel` and +`ExploitPathAnalysisEvidenceModel`: one closed evidence envelope is assembled +from admitted inputs and records: + +- exact taxonomy, relation, profile, model, and checker ids/revisions/digests; +- declared bounds and realized checked counts; +- deterministic completed relation outcome or typed unsupported outcome; +- a `BehavioralClaimBindingModel` using + `assurance_axis=bounded-test`, `assurance_status=tested`, + `evidence_scope=finite`, and `quantifier_scope=finite-cases`; +- limitations and explicit nonclaims; and +- either bounded positive evidence refs or one safe counterexample ref/digest. + +The positive outcome is named “no counterexample found within the declared +finite bounds,” not `opaque`, `proved`, `verified`, `model-checked`, +`conformant`, or an unqualified `passed`. The claim's evidence boundary names +only the exact finite model and declared strategy/scheduler/order domain. A +successful exhaustive loop over that artifact is bounded testing. It is not +`model-check`, `proof`, +`runtime-enforcement`, `backend-realization`, or `backend-conformance`, and it +must not use universal claim quantifiers. + +Counterexamples use checker-generated safe ordinals/labels, governed refs, +counts, and digests. They do not echo caller-controlled point ids when those +ids may reveal secrets, and they never serialize raw worlds, secret values, +participant memory, policy bodies, supervisor state, observation content, +credentials, backend objects, or rejected input. Hashing secret-bearing +content does not make it safe to publish. + +Replay must recompute and compare every source/profile/model/checker/result +join and reject any changed bound, input, profile, materializer/checker +configuration, outcome, count, evidence ref, or counterexample identity. A +replay mismatch is an evidence failure, not a fresh opacity disposition. +Malformed input remains an ingress/operational error and does not produce an +analysis evidence envelope. + +The bounded checker authenticates neither a source artifact nor the +materializer that projected it. Those input assertions remain covered by the +normalized-input digest so replay detects changes, but the evidence envelope +does not repeat them as provenance. It declares a +`normalized-input-only` provenance scope and an explicit source/materializer +authenticity nonclaim. A future trusted materializer may strengthen this +boundary only by resolving the actual source and recomputing those joins. + +### Advance catalog assurance honestly + +The current catalog revision is `rev7`; the implementation program's older +`rev5` wording is historical, not an implementation pin. If #961 changes the +opacity relation's checker or evidence state, it must advance the current +catalog revision once and move every live taxonomy-revision producer, +byte-identical fixture, claim surface, policy test, reader-facing authority, +and embedded claim fixture together. + +The opacity assurance change is narrow: checker implementation becomes +positive and bounded-test evidence becomes executable. Model-check, proof, +runtime enforcement, backend declaration, backend realization, and backend +conformance remain negative. The legacy `implementation_status` aggregate must +remain consistent with the positive checker axis. Do not change only the +profile or only the catalog assurance record. + +## Canonical Incumbents To Reuse + +| Concern | Canonical incumbent and required use | +| --- | --- | +| Opacity meaning | ADR-099 and `specs/formal/participant-semantics/participant-predicate-opacity.md`; do not redefine possible points, information cells, active strategies, release, memory, or relation boundaries in conformance code. | +| Information-flow carriers | ADR-085/095 and SEM-230 exact-cut policy, projection, adaptive strategy, declassification, memory, scheduler/environment, and order semantics. | +| Relation and claim authority | `contracts/concept-authority/behavioral-relations-v1.json`, `BehavioralRelationCatalogModel`, `BehavioralClaimBindingModel`, `load_behavioral_relation_catalog()`, `validate_behavioral_claim_binding()`, and `tools/check_behavioral_relation_claims.py`. | +| Profile corpus | `contracts/profiles/`, `corpus_family_root(PROFILES)`, installed-corpus force includes, hardened backend/random-stream profile-id and identity checks, and strict JSON ingress. The relation profile is a distinct family, not a semantic, backend, validation, or random-stream profile. | +| Closed contracts and digests | `ContractModel(extra="forbid")`, `parse_bounded_json_object()`, `PrefixedDigestString`, `SourceArtifactIdentityModel`, RFC 8785 `canonical_json_digest()` / `canonical_contract_digest()`, and exact ref/revision pairing. | +| Analysis service | `raes_processor.satisfiability` and `raes_processor.exploit_path`: normalized closed inputs, typed evidence/outcomes, bounded preflight diagnostics, deterministic engines, canonical selection, value-free operational failures, and replay. Do not copy either domain theory. | +| Behavioral-validation discipline | `BehavioralProbeBinding`, claim admission, input/checker digests, capability identity, stable diagnostics, and fail-closed outcomes. Reuse the discipline, not the subject/backend runner or report shapes. | +| Diagnostics and errors | `Diagnostic`, `DiagnosticModel`, `Severity`, stable domain-specific codes, bounded preflight accumulators, typed unsupported outcomes, and the value-free satisfiability/exploit-path operational-error posture. Do not import conformance merely to reuse its sanitizer or add an opacity exception hierarchy. | +| Schema publication | `schema_bundle()`, `tools/generate_contract_schemas.py`, hand-governed `contracts/schemas/`, valid/invalid conformance fixtures, the conformance validator registry, schema-publication entries/hashes, and generated/publication drift gates. | +| Evidence/artifacts | Existing canonical JSON, digest, safe-ref, root-confined artifact-path, atomic-write, and redaction-gate patterns. Introduce no mutable witness store. | +| Workflow | `.ground-control.yaml`, `.gc/plan-rules.md`, `noxfile.py`, requirement governance, concept/claim/schema/JSON/docs gates, and `tools/verify_all.py`. Because branch `961-participant-opacity` has no requirement UID, workflow commands use `RAES_REQUIREMENT_UID=ASR-535`. | + +Package boundaries stay intact: `raes_contracts` owns the portable profile, +normalized input, outcome/evidence, and resolution; `raes_processor` owns +deterministic finite evaluation and replay; `raes_conformance`, `raes_runtime`, +and `raes_backend_protocols` are not changed by #961. + +## Cross-Cutting Layers And Security Posture + +1. **Profile/config ingress.** The profile is bounded UTF-8 JSON, duplicate + members and non-finite numbers are rejected, the root is an object, the + profile id is grammar-checked before path construction, and the path comes + from the packaged/source corpus root. There is no YAML expression, env + binding, arbitrary import, URL fetch, or caller-selected production root. +2. **Closed schema and semantic gate.** `ContractModel`, the published schema, + valid/invalid fixtures, local validators, and one cross-reference validator + reject unknown fields, missing coordinates, invalid discriminators, + unresolved refs, inconsistent observer/coalition shapes, and ref/revision + mismatch. A Python-only shape is not a published contract. +3. **Relation/claim gate.** Catalog, relation, profile, projection, carrier, + assurance axis, evidence scope, quantifier, and nonclaims are joined before + execution and again before evidence projection. A present profile string is + insufficient. +4. **Finite-model admission gate.** Exact declared bounds, realized counts, + reachability, strategies, scheduler/environment choices, order variants, + source/profile/materializer/checker digests, and deterministic resource caps + are validated before evaluation. Malformed input fails before evidence; + unsupported dimensions and deterministic cap exhaustion are typed + unsupported; unexpected timeout/operational failure emits no evidence. + Vacuity and partial execution cannot pass. +5. **Authentication and runtime-policy boundary.** The #961 checker is + in-process and pure; it does not traverse HTTP authentication, RUN-319 + authorization, API-407 capability, runtime persistence, or backend gates + and therefore makes no claim about them. A future API wrapper must reuse + `create_control_plane_app()`, strict security defaults, identity/role/target + binding, request-size limits, fingerprints/idempotency, and audit rather + than exposing a new unauthenticated checker endpoint. +6. **Secret-handling boundary.** Profiles, models, fixtures, diagnostics, + counterexamples, evidence, logs, and review output use synthetic bounded + values and safe refs/digests only. Raw secret values, possible worlds, + memories, policy/supervisor internals, participant content, credentials, + rejected values, and environment dumps are excluded. +7. **Diagnostic/error-envelope gate.** Expected failures use stable codes, + schema-derived safe addresses, and bounded generic messages. Do not + interpolate `str(exc)`, Pydantic `input_value`, rejected keys/ids, model + content, tracebacks, or tool output. If later exposed over HTTP, unexpected + failures retain `{"detail":"internal server error"}`. +8. **Artifact/persistence gate.** Validate the complete evidence and claim + before canonical serialization. Durable evidence uses safe root-confined + names, atomic writes, content digests, replay, and the existing redaction + gate. It does not enter `RuntimeSnapshot.metadata`, operation details, + `AuditEvent`, a log line, `BackendConformanceReport`, or a new database. +9. **OS/process exposure gate.** The default checker is an in-process, + deterministic, fixture-only function with no network, subprocess, daemon, + socket, privilege, or secret loader. Profile/model content, secrets, + witnesses, credentials, and full results never enter argv, environment + variables, filenames, stdout/stderr, shell history, or host logs. +10. **Governance gate.** Profile schema, corpus packaging, fixture validation, + catalog revision, current claim producers, formal/docs wording, + schema-publication hashes, and requirement traceability move through their + existing gates. No issue-local verification script or schema authority is + added. + +## Whole-Repository Surfaces In Scope + +- **Normative authority:** ADR-099, SEM-231, behavioral relation/catalog + assurance, the new relation-profile contract, profile corpus, published + schema, fixtures, and schema-publication record. +- **Shared consumers:** every model embedding `BehavioralClaimBindingModel`, + behavioral-validation and necessity-validation probes, conformance report + claims, scientific-completeness and experiment-study fixtures, evidence-run + production, public claim guidance, and claim-policy scanning. +- **Bounded execution:** processor analysis preflight, deterministic opacity + evaluator, typed unsupported/invalid boundaries, replay, safe + result/counterexample evidence, and focused negative fixtures. +- **Packaging:** `raes_contracts` exports, contract schema bundle, validator + registry, contract corpus force include, wheel/sdist corpus tests, and + source/install loader parity. +- **Verification:** profile schema/semantic fixtures, all six issue negative + cases, catalog/profile/claim cross-reference tests, digest determinism, + sanitization tests, vacuity/truncation tests, claim-policy gate, docs build, + repo policy, requirement governance, and canonical verification. + +## Extensibility Seam + +The stable seam is: + +```text +catalog relation + -> resolved closed relation profile + -> digest-bound normalized finite carrier + -> trusted materializer/checker configuration + -> axis-specific claim + safe evidence +``` + +The common header owns relation, taxonomy, projection, carrier, and evidence +identity. The discriminated opacity payload owns observer, secret, memory, +strategy, supervisor, release, scheduler/environment, time/order, and support +semantics. Consumers reference the profile; they do not copy its coordinates. + +This lets #962 reuse the same finite profile and carrier with +`assurance_axis=model-check`, and lets a later relation add a closed parameter +variant without editing every claim-bearing DTO. Larger domains, another +observer, active strategies, coalitions, K-step horizons, releases, or order +models add profile/model artifacts.

SCE-003. + +This note fixes the architecture boundary for observable, bounded adaptive +difficulty over declared scenario variants. It is guidance only: it does not +add SDL syntax, contracts, schemas, policy algorithms, runtime behavior, +persistence, fixtures, tests, APIs, or an implementation plan. + +ADR-084 remains authoritative. Adaptation is a governed consumer of an +immutable admitted baseline; it cannot become a second scenario-selection, +trial-realization, participant-control, or archival-run lifecycle. + +## Existing Authorities And Current Gap + +- ADR-084, `raes.variation`, `raes.experiment_selection`, + `raes.selected_scenario`, `AdmittedTrialPlanModel`, + `compile_admitted_trial_plan()`, and `realize_admitted_trial_entry()` already + own bounded scenario-family variation, experiment selection, immutable trial + intent, deterministic realization, and preallocated run identity. A live + adaptive policy cannot call those concepts "runtime mutation" and alter the + current run. +- `ExperimentSpecModel`, `ExperimentStudyFactorModel`, + `ExperimentRunAllocationPlanModel`, `ExperimentRunModel`, and + `ExperimentStudyModel` already own pre-run design, factors, compared + conditions, allocation, archival execution provenance, validity notes, and + analysis. Fixed, adaptive, and scaffolded conditions belong here rather than + in SDL topology or backend configuration. +- SDL `WorkflowStep.execution_mode`, `WorkflowStep.scaffold_refs`, + `ParticipantObservationBoundary`, and the semantic checks in + `SemanticValidator._verify_workflows()` already own declared scaffolded work + and the instruction, starter-file, scaffold-instruction, and subtask-guidance + boundaries that may be exposed. SCE-003 must select only among such declared + carriers; it must not invent guidance text or a second scaffold schema. +- ADR-066, `ExperimentCaptureSpecModel`, `ExperimentEvidenceRecordModel`, + `ExperimentDerivedMeasureModel`, `ExperimentAugmentationDisclosureModel`, + and `ExperimentRunTraceabilityModel` already separate observation intent, + raw evidence, derived measures, realized augmentation, and run provenance. + A policy input is not evidence merely because it was logged. +- ADR-085/095, participant decision-surface v2, participant crossing, + participant inject delivery, exposure policy, delivery, and observation + records already own participant-facing disclosure at an exact state cut. + Producing guidance is not authorization, delivery, acknowledgement, or proof + that the participant used it. +- API-409 `ParticipantInterventionOccurrenceModel` means a mixed-control + intervention against an existing participant action, control, or attempt. It + is not a generic adaptive-difficulty event. An adaptive decision may + reference an API-409 occurrence when those exact semantics apply, but it + must not overload or duplicate that carrier. +- `ExperimentAugmentationDisclosureModel` is a run-level disclosure of + processor/backend augmentation and comparability effects. It is not the + policy decision, trigger record, delivery receipt, or operational event. +- `ControlPlaneStore`, `ControlPlaneOperationRecord`, request fingerprints, + idempotency keys, compare-and-set participant history heads, and `AuditEvent` + already own live operational durability and audit. Archival run/evidence + contracts remain separate and must not be reconstructed from mutable + snapshots or audit text. + +The missing surface is a closed adaptive-policy declaration and an append-only +decision/intervention provenance record that compose those incumbents by +reference. The implementation must not add another variation domain, scenario +binder, workflow language, observation model, participant delivery model, +run/study record, repository, exception hierarchy, or policy engine. + +## Architecture Decisions And Guardrails + +### One declared policy, one exact decision, and separately evidenced effects + +Use one versioned adaptive-policy family with an explicit experiment condition: + +- `fixed`: no adaptive action is permitted; +- `adaptive`: a declared policy may choose a permitted action from current, + evidence-bearing observations; or +- `scaffolded`: declared guidance is available under a fixed or explicitly + declared trigger, without implying that the challenge itself was rescaled. + +The condition is not inferred from whether an intervention happened. A fixed +condition that unexpectedly contains an intervention is invalid, not +silently reclassified. Benchmark profiles default to `fixed`; adaptation must +be explicitly declared in the experiment design and run provenance. + +A policy declaration identifies: + +- stable policy id, version, and immutable digest; +- exact baseline experiment, admitted plan/entry, run, task, and scenario + family/snapshot references as applicable; +- named difficulty dimensions and named variants that reference existing + variation points, admitted outcomes, factors, and declared scaffold/action + carriers rather than copying them; +- exact observation-source roles and evidence requirements; +- decision cadence in a named logical-time, decision-epoch, event-order, or + state-cut domain; +- a closed trigger/evaluator profile, either exact typed thresholds or a + governed versioned policy reference; +- a finite allowlist of actions and affected semantic references; +- bounds such as maximum interventions, direction/range limits, cooldown or + hysteresis, and terminal/unsupported disposition; and +- validity and comparability disclosures required when the policy acts. + +Policy ids and profiles are governed identifiers, not import paths, commands, +callbacks, entry points, URLs, prompts, plugin names, or aliases such as +`latest`. Free-form policy `parameters`, expression trees, JSON Patch, and +backend-native option maps are not admitted extension mechanisms. + +Difficulty ordering is policy-local and explicit. A variation point does not +become intrinsically "easy" or "hard", and faster completion is not a universal +competence measure. A named variant is a reference to a complete, admitted +selection or scaffold/action profile; it is not another scenario identity, +mutable preset, or partial patch. + +### Policy inputs are exact-cut evidence, not ambient state + +Each decision binds the exact current state cut and only the observation +records, evidence records, or derived measures admitted by the policy. +Observation ids, source roles, capture/evidence refs, timestamps/order +coordinates, sensitivity, redaction, and derivation profile must resolve. + +Raw logs, mutable counters, wall-clock time, host load, backend-private state, +environment variables, final outcomes from the future, hidden answer material, +and unsealed evaluator details are not implicit policy inputs. If a policy is +authorized to use a hidden or assurance-only source, that source remains out of +the participant view and its output still passes the independent +authorization/declassification/disclosure gates. Using hidden truth as a +policy input never authorizes revealing it. + +The policy decision record is append-only and carries policy identity/version/ +digest, prior policy state, exact cut/cadence coordinate, input observation +refs, trigger result, selected action ref, affected semantic refs, disposition, +timing, evidence/provenance refs, and declared validity effect. The action +attempt, realization outcome, participant delivery, participant observation, +and measured downstream effect remain separate referenced occurrences. + +A repeated request with the same policy, cut, observation set, and idempotency +identity must return the same decision or conflict. Stale, future, +cross-run/cross-episode, already-consumed, incomparable, or policy-mismatched +cuts fail before any side effect or history append. + +### In-run actions are forward-only uses of admitted carriers + +An in-run adaptive decision may only request an action already admitted for +that run, for example: + +- disclose one declared scaffold reference through the existing observation + boundary, exposure, crossing, delivery, and observation path; +- request a declared participant-directed inject or mixed-control operation, + when that exact carrier and authority are already present; or +- request an existing compiled workflow/action transition that independently + passes its normal predicate, action-admission, apparatus, and backend gates. + +The adaptive policy does not execute the effect itself. It returns a typed +decision that the owning runtime service validates and dispatches through the +incumbent carrier. Unsupported carrier/backend capability produces an explicit +unsupported or denied record, not a private fallback. + +No in-run action may: + +- change an SDL variation-point selection or instantiation binding; +- add/remove/retarget topology, declarations, objectives, workflows, or + participant identities; +- change task factors, condition assignment, trial coordinate, run id, + apparatus selection, random-stream address, seed, or admitted timeout; +- rewrite, delete, reorder, or reinterpret past events, evidence, delivery, or + observations; or +- bypass participant information-flow, action-admission, capability, + realization-envelope, or backend validation. + +### A harder follow-up variant is a new admitted trial + +When the selected action changes scenario-family difficulty rather than using +an already admitted in-run carrier, the output is a proposal for a derived +follow-up trial. It re-enters the existing experiment selection, +`compile_admitted_trial_plan()`, `select_scenario_family()`, ordinary +instantiation/admission, processor planning, and one-entry realization path. + +The follow-up receives a new trial coordinate, plan entry, and `run_id`. Its +run uses existing `trial_provenance` and `derived_from_refs` to link the source +run and adaptive decision. It does not reuse or supersede the source run +identity, mutate its snapshot, or continue its random streams by convention. +Admission failure remains a visible failed/unsupported decision outcome; the +policy cannot clamp, resample, repair, or select another backend silently. + +### Validity and comparison are experiment concerns + +Fixed, adaptive, and scaffolded conditions must be distinct factor levels and +condition assignments in experiment/study allocation. Every archival adaptive +run reconciles its declared policy condition with the actual decision records, +augmentation disclosures, evidence, and derived follow-up links. + +Comparisons involving adaptive runs require an analysis plan and validity note +that state the estimand and treatment received. A fixed-versus-adaptive +comparison may estimate a policy effect; it must not present participants as +having faced the same fixed treatment. Per-run difficulty paths and guidance +exposure are post-allocation treatment facts, not baseline factors to rewrite. +Missing, denied, unsupported, or evidence-lost interventions remain explicit +and feed the existing missing-data/invalidation rules. + +## Required Incumbents And Cross-Cutting Reuse + +- **SDL and scenario-family authority:** `load_sdl_yaml`, bounded source and + composition profiles, `Scenario`, `ExpandedScenario`, + `InstantiatedScenario`, `SemanticValidator`, `raes.variation`, + `validate_experiment_selection_against_family()`, + `select_scenario_family()`, `instantiate_scenario()`, + `admit_instantiated_scenario()`, `InstantiationProvenance`, and canonical + instantiated-snapshot bytes/digests. +- **Trial identity and realization:** `ExperimentSpecModel`, + `ExperimentSelectionPolicyModel`, `AdmittedTrialPlanModel`, + `revalidate_admitted_trial_plan()`, `compile_admitted_trial_plan()`, + `realize_admitted_trial_entry()`, `TrialRunProvenanceModel`, + `validate_admitted_trial_run()`, and + `validate_admitted_trial_study()`. +- **Scaffold and action authority:** `WorkflowStep.execution_mode`, + `WorkflowStep.scaffold_refs`, `ParticipantObservationBoundary`, + `ParticipantInformationBoundaryClass`, participant inject delivery, + `ParticipantActionAdmissionRequest`, participant decision-surface v2, + participant crossing, exposure, delivery, observation, and API-409 control + occurrences where their narrower semantics apply. +- **Experiment evidence and validity:** `ExperimentCaptureSpecModel`, + `ExperimentEvidenceRecordModel`, `ExperimentDerivedMeasureModel`, + `ExperimentAugmentationDisclosureModel`, `ExperimentRunTraceabilityModel`, + `ExperimentRunModel`, `ExperimentStudyModel`, + `validate_experiment_run_against_task()`, and + `validate_experiment_study_against_tasks_and_runs()`. +- **Validation and diagnostics:** `ContractModel(extra="forbid")`, + `ValidationBasisDisclosureModel`, `Diagnostic`, `DiagnosticModel`, + `CompilationFailure`, `sanitized_failure_message()`, `x-raes-invariants`, + strict scalar types, canonical JSON/JCS digest helpers, and exact reference/ + digest equality.

Reject unknown fields, coercive scalar forms, + non-finite numbers, unbounded rule/action graphs, ambiguous policy versions, + and undeclared refs before contextual validation. +2. **Schema and publication gate.** Any portable policy or intervention + contract is published from its owning `raes_contracts` model with exact + generated parity, positive/negative fixtures, conformance registration, + semantic annotations, compatibility classification, and a + `schema-publication-manifest.json` change-ledger entry. The published schema + remains normative; do not hand-edit only Python or generated JSON. +3. **Experiment and trial gate.** Policy condition, factor/level/condition, + baseline plan/entry/run, named variant, variation point/outcome, action, + task, apparatus, and profile refs resolve exactly against concrete, + digest-matched artifacts. Fixed conditions reject intervention authority. +4. **Policy-input and exact-cut gate.** Reconstruct inputs from trusted + evidence/participant carriers, resolve the named order domain and current + state cut, enforce cadence/bounds/hysteresis, and reject stale, future, + duplicate, cross-scope, unsupported, or loss-hidden inputs before selecting + an action. +5. **Participant information-flow gate.** Participant-facing guidance passes + observation-boundary projection, current exposure policy and markings, + crossing authorization, transformation/declassification as applicable, + delivery, and observation. Operator/auditor visibility, policy access, or + evidence retention is not participant disclosure. +6. **Runtime, apparatus, and backend gate.** Revalidate the chosen action + against the compiled run, current lifecycle/history heads, action/control + authority, capability declaration, realization envelope, backend + `validate()` result, and effect-specific admission. A policy decision alone + grants none of those authorities. +7. **Authentication and authorization gate.** Any remote surface reuses + `ControlPlaneSecurityConfig.strict_defaults()`, bearer or verified-proxy + identity, target binding, read/mutating role separation, participant/ + controller or audience scope where relevant, request-size guards, + idempotency/fingerprint conflicts, and append-only audit. Policy execution, + evidence reads, participant disclosure, follow-up admission, and artifact + dereference are separate deny-first permissions. +8. **Secret, environment, and configuration gate.** Policies, observations, + decisions, variants, digests, fixtures, and provenance contain no + credentials or resolved secrets. Use the existing typed + literal/secret-reference and protected-sink patterns only if a declared + action genuinely needs a secret. Thresholds, cadence, bounds, policy + version, and baseline identity come from sealed artifacts, never ambient + environment, process-global state, mutable backend defaults, or an + unvalidated config file. +9. **OS/process exposure gate.** The reference resolver should remain + in-process over typed DTOs. A future external policy adapter requires a + separately governed boundary using fixed argv, no shell, bounded stdin or + private files, controlled working directory, timeout, output bounds, and + redaction. Tokens, policy bodies, observations, hints, plans, secret refs, + hidden truth, and parameter maps never enter argv, process titles, + filenames, environment captures, stdout/stderr, or logs. +10. **Error-envelope and logging gate.** Expected failures use bounded, + canonically ordered `Diagnostic`/`DiagnosticModel` records with safe codes, + domains, JSON-pointer addresses, and fixed messages. Do not render raw + Pydantic input, observations, thresholds, hints, policy bodies, hidden + refs, secret locators, paths, backend output, exception text, or + tracebacks. HTTP retains the redacted + `{"detail":"internal server error"}` fallback; 4xx details are bounded and + value-free. Logs/audit carry safe ids, digests, versions, cuts, counts, + dispositions, and durations only. +11. **Persistence and archival gate.** Persist in-flight decision identity, + current policy state, idempotency, and history heads through the existing + operational store and atomic transition pattern. Archive observation, + intervention, delivery/effect evidence, run disclosure, and follow-up + lineage through the experiment/evidence artifacts. Do not use + `RuntimeSnapshot.metadata`, operation `details`, tags, logs, or audit blobs + as the only provenance authority. +12. **Run/study reconciliation gate.** Revalidate each run against its task, + admitted entry, declared adaptation condition/policy, decision records, + participant crossings/deliveries, augmentation disclosures, evidence, + results, and derived follow-ups. Revalidate study allocation and analysis + so adaptive treatment cannot be compared as if it were fixed. + +## Extensibility Seam + +The seam is a pure, versioned policy-resolution operation over explicit +parameters: + +```text +(policy identity/version/digest, + baseline refs, condition, named policy state, + exact state cut, admitted observation refs, + cadence and bounds) + -> one typed decision or bounded diagnostics +``` + +The decision names one predeclared action and carries no side effect. Separate +runtime adapters realize the action through existing scaffold, crossing, +control, workflow, or follow-up-trial authorities and append separately typed +outcome evidence. + +The next reasonable change—a new threshold profile, observation source, +difficulty dimension, scaffold carrier, policy-state transition, or +follow-up-selection strategy—extends a closed union or governed profile and its +fixtures.

Candidates pass ordinary authoring, trust, composition, semantic validation, experiment binding, and trial admission. +## Executable SCE-003 v1 Profile + +Adaptive difficulty is declared in the experiment run plan as a bounded +`DifficultyPolicyRegistryModel`. The registry contains named variants that +reference existing selection/scaffold/action carriers, policy-local ordered +dimensions, immutable fixed/adaptive/scaffolded policies, and one default +policy that is always fixed. + +Every allocation condition has a `difficulty_condition` with fixed as its wire +default. Adaptive and scaffolded conditions also name an exact +`difficulty_policy_id`; the id resolves the registry and its condition must +match. Variant selection references resolve only existing fixed experiment +selection policies. A difficulty variant is therefore an admitted experiment +coordinate, not an unvalidated patch or runtime preset. + +The supported reference evaluator is the digest-bound +`adaptive-threshold-v1@1.0.0` profile. Resolution is pure over the policy, +exact state cut, evidence-bearing observation references, expected decision +history head, intervention count, and idempotency identity. It enforces +freshness, run/episode/order scope, threshold priority, cadence, cooldown, and +maximum interventions, then returns one sealed decision or bounded +diagnostics. Another digest-bound evaluator remains a valid declaration but +returns `unsupported`; it never falls back to the reference profile. +`ADAPTIVE_THRESHOLD_PROFILE_DIGEST` publishes the exact supported profile +digest, and resolver support matches the complete id/version/digest tuple. + +Decision history is append-only. Each `DifficultyDecisionRecordModel` binds +the policy id/version/digest, request fingerprint, prior and resulting history +heads, exact cut, evidence references, trigger, selected action, typed affected +references, disposition, time, and validity effect. Observation values are +transient resolver inputs and are not copied into the archival decision. + +Selected effects are separate `DifficultyInterventionRecordModel` records. +The closed affected-reference kinds are scaffold, participant inject, +participant control, workflow action, and scenario variant, and each must +match its action carrier. Effect-capable records require occurrence, evidence, +or follow-up-run provenance. A scenario-variant action is only a follow-up +trial proposal: its run reference differs from the source, and ordinary +selection, plan admission, instantiation, and realization still allocate its +coordinate and identity. + +`ExperimentRunModel.difficulty_provenance` archives the exact policy snapshot, +ordered decisions, intervention outcomes, and comparison disposition. Its +records belong to the archival run and fall inside its time window. Absence of +this optional field preserves legacy fixed semantics. Study condition matching +treats fixed, adaptive, and scaffolded as distinct treatments; every non-fixed +study condition requires an analysis plan and explicit validity notes. +`validate_experiment_difficulty_against_spec()` additionally binds a run to the +canonical authoring-input digest, task, allocated condition, and exact admitted +policy snapshot. + ## Compatibility Invariants ### SVR-035 — Static SDL is a singleton family From 2d2643416e02ceedf9bba722c25ee38e6b54141b Mon Sep 17 00:00:00 2001 From: Brad Edwards Date: Thu, 30 Jul 2026 07:19:39 +0200 Subject: [PATCH 20/30] refactor: group batch execution receipt builder params for the SonarCloud parameter-count gate --- .../raes_processor/trial_scheduler.py | 76 +++++++++++++------ .../tests/test_sce_006_batch_scheduler.py | 32 ++++---- 2 files changed, 68 insertions(+), 40 deletions(-) diff --git a/implementations/python/packages/raes_processor/trial_scheduler.py b/implementations/python/packages/raes_processor/trial_scheduler.py index a562f72d7..619b33b86 100644 --- a/implementations/python/packages/raes_processor/trial_scheduler.py +++ b/implementations/python/packages/raes_processor/trial_scheduler.py @@ -67,6 +67,36 @@ class BatchSchedule: entries: tuple[ScheduledEntry, ...] +@dataclass(frozen=True) +class AttemptOutcome: + """The realized disposition and portable evidence of one execution attempt. + + ``cleanup_receipt_ref`` names the cleanup receipt proving the attempt's + terminal cleanup; ``operation_refs`` are control-plane operation ids and + ``attempt_deadline`` is an optional RFC 3339 deadline. + """ + + execution_attempt_id: str + trial_outcome: TrialOutcome + cleanup_receipt_ref: str + operation_refs: Sequence[str] = () + attempt_deadline: str | None = None + + +@dataclass(frozen=True) +class AllocatorGrant: + """The downstream allocator's live-lease parallelism decision for one attempt. + + ``effective_parallelism`` (serial by default) and ``lease_evidence_refs`` are + the allocator's decision and its live lease evidence; ``isolation_proof_ref`` + defaults to the schedule's admitted proof for a bounded-parallel attempt. + """ + + effective_parallelism: int = 1 + lease_evidence_refs: Sequence[str] = () + isolation_proof_ref: str | None = None + + def plan_batch_schedule(plan: AdmittedTrialPlanModel) -> BatchSchedule: """Compute the canonical dispatch order and admitted parallelism ceiling. @@ -120,51 +150,49 @@ def build_batch_execution_receipt( plan_entry_id: str, *, receipt_id: str, - execution_attempt_id: str, - trial_outcome: TrialOutcome, - cleanup_receipt_ref: str, - effective_parallelism: int = 1, - lease_evidence_refs: Sequence[str] = (), - isolation_proof_ref: str | None = None, - operation_refs: Sequence[str] = (), - attempt_deadline: str | None = None, + outcome: AttemptOutcome, + grant: AllocatorGrant | None = None, ) -> BatchExecutionReceiptModel: """Record one attempt's evidence, binding it to this schedule's decision. - ``effective_parallelism`` and ``lease_evidence_refs`` are the downstream - allocator's decision and its live lease evidence; the effective bound cannot - exceed the schedule's admitted ceiling.

+Requirements: `SEM-231`, `ASR-535`. + +This note records repository-wide architecture guardrails for the finite-state +participant-opacity model-check lane. It is guidance only. It does not define a +new relation or profile, publish a model or evidence schema, implement or run a +model checker, change catalog assurance, establish opacity, prove an unbounded +theorem, enforce a runtime policy, or certify a backend. + +## Decisive Current-State Finding + +Issue #962 is a new assurance executor over the existing SEM-231 authority, not +a new opacity subsystem. + +- ADR-099, the SEM-231 formal specification, and behavioral-relation catalog + `rev7` already own the one-sided possibilistic relation, possible points, + information cells, active-strategy quantifier, supervisor visibility, + release, memory, order, and exact relation boundaries. +- `participant-opacity-baseline-v1@sem-231/rev1` and + `BehavioralRelationProfileModel` already close the semantic coordinates. + `validate_behavioral_claim_binding()` already joins the catalog, profile, + carrier, projection, assurance axis, and claim. +- #961 already supplies strict JSON ingress, the normalized possible-point + primitives, finite-domain admission, the opacity information-cell kernel, + deterministic counterexample selection, digest-bound evidence, replay, and + safe operational failures. +- #961 deliberately trusts an input assertion that its possible-point carrier + is complete. It scans that supplied carrier; it does not derive reachability + from initial states and transitions. Relabeling its result + `assurance_axis=model-check` would therefore be an assurance escalation, not + #962. +- `raes_processor.exploit_path` supplies the closest incumbent execution + pattern for #962: a closed normalized graph, canonical graph traversal, + explicit explored counts, typed unsupported outcomes, deterministic + witnesses, and replay. Its depth-limited result semantics are not reusable + for a complete model check. `raes_processor.satisfiability` supplies the pinned + tool-configuration and evidence-join pattern. Neither domain theory should + be copied. + +The smallest coherent addition is a distinct closed finite transition-model +input and model-check evidence envelope in `raes_contracts`, plus a +deterministic explicit-state explorer in the existing +`raes_processor.participant_opacity` package. The explorer derives the reachable +possible-point carrier and then reuses the #961 opacity kernel. No new relation, +profile registry, policy engine, conformance runner, exception hierarchy, +logger, store, endpoint, or workflow is justified. + +## Architecture Decisions And Guardrails + +### Keep one semantic authority and one profile seam + +The model check uses relation `participant-predicate-opacity`, the current +behavioral taxonomy, the shared profile loader, and the shared claim validator. +It does not define `model-checked-opacity`, copy SEM-231 coordinates into a +checker-local profile, or use a generic graph property as a substitute for the +relation. + +The governed profile remains the authority for observer or coalition, secret +predicate, initial information, observation projection, memory and horizon, +passive or active strategy domain, supervisor visibility, release, scheduler +and environment domains, nondeterminism, order, time, and probability scope. +The finite model supplies one exact realization of those coordinates; it does +not override them. + +The shipped baseline remains passive, one-sided, possibilistic, untimed, +progress-insensitive, and total-order. Tests may inject another closed profile +to exercise active strategies, coalitions, memory, release, or order failures. +A positive result for such a variant requires its own governed profile artifact +and exact ref/revision/digest; an in-memory mutation is test evidence only. + +### Add a transition model; do not overload the #961 carrier + +The model-check input needs a separate schema because it has different +authority and assurance invariants from +`ParticipantOpacityAnalysisInputModel`. It must contain, in canonical form: + +- model id, revision, source identity, and digest-bound materializer or model + provenance; +- exact profile and taxonomy joins; +- the complete finite declared state set, initial-state set, and transition + relation; +- stable canonical state and transition ordinals and safe references; +- the strategy, scheduler, environment, order, cut/horizon, observation, + memory, release, coalition, and secret labels needed to derive SEM-231 + possible points; +- exact declared counts for states, transitions, initial states, strategies, + scheduler/environment pairs, order variants, and evaluation points; and +- an explicit declaration that the transition artifact is the complete model + being claimed, not a sample, depth prefix, or timeout-truncated export. + +Reuse `ContractModel`, `PrefixedDigestString`, `SourceArtifactIdentityModel`, +the existing safe observation-cell coordinate vocabulary, and the existing +safe-ref/revision/digest primitives where their meanings match. Do not reuse +`OpacityPossiblePointModel` as a model state: its caller-supplied `reachable` +field is part of #961's bounded-carrier semantics, while #962 must derive +reachability. Do not fork the shared coordinate semantics or change the #961 +input/evidence invariants, which correctly pin that lane to +`bounded-test/tested/finite/finite-cases`. + +The transition model does not carry a caller-supplied `reachable` verdict or +information-cell id. Reachability is derived from the declared initial states +and transitions. Information cells are derived from the profile-relevant +initial-information, observation, memory, release, coalition, strategy, and +order coordinates. State reduction must not merge states with different values +for any of those coordinates without a separate preservation proof. + +### Make exhaustive reachability the assurance boundary + +The checker performs a canonical fixed-point traversal of the finite transition +relation. It terminates because the admitted state set is finite, not because a +depth, wall-clock, or iteration timeout was reached. + +Admission rejects duplicate or unresolved ids, noncanonical order, transition +endpoints outside the state set, missing initial states, count/digest mismatch, +and model/profile domain mismatch. Every active strategy declared by the +profile must have its required initial and transition domain, and actual and +witness points remain under the same strategy. Scheduler/environment and order +coverage must exactly match the profile's declared domains and supported +quantifier treatment. + +The shipped baseline has singleton scheduler and environment domains, so its +v1 quantifier posture is unambiguous. A future multi-valued scheduler or +environment profile must first declare its quantifier order in the shared +relation profile. The engine must not guess universal versus existential +treatment from a tuple of refs. + +Evidence records both declared and explored state/transition counts, reachable +evaluation-point and secret-point counts, and counts per strategy and declared +scheduler/environment/order domain. Unreachable declared states remain visibly +distinct from explored reachable states and cannot satisfy an opacity +obligation. + +A depth bound, sampled schedule, early counterexample exit, skipped strategy, +missing domain cell, timeout, resource-cap interruption, or partial frontier +cannot produce a model-checked result. Valid but unsupported profile +dimensions, vacuous secret domains, and deterministic pre-admission cap +exhaustion are typed non-positive outcomes. Malformed models and unexpected +operational failures emit no evidence envelope. + +### Reuse the opacity kernel without relabeling bounded evidence + +After complete reachability, the explorer materializes the canonical reachable +SEM-231 possible points and invokes one extracted internal opacity kernel from +the #961 implementation. Both lanes must share: + +- information-cell construction; +- the universal reachable actual-secret-point scan; +- same-strategy witness selection; +- one-sided secret polarity; +- deterministic lowest-canonical counterexample selection; and +- vacuity and safe-counterexample rules. + +The model-check service must not call +`analyze_participant_opacity_input()` and relabel its +`ParticipantOpacityAnalysisEvidenceModel`. The model-check evidence separately +binds the transition model, exploration configuration, explored fixed point, +derived carrier digest, result, and `model-check` claim. Agreement tests compare +#961 and #962 on shared finite carriers and independently assert the expected +outcome; equality alone is not an oracle. + +### Use a deterministic in-process explicit-state tool + +The proportionate tool is a versioned in-process explicit-state explorer in +`raes_processor.participant_opacity`. The property requires graph reachability +and an information-cell check; the existing Z3 adapter, a new external model +checker, or a shell wrapper adds no semantic capability for this finite +baseline. + +The closed checker configuration records the tool id and semantic version, +algorithm revision, traversal and ordering rules, opacity-kernel revision, +counterexample selection, supported profile dimensions, and deterministic +state/transition/resource caps. Its canonical digest and the implementation or +source revision are evidence. Measure the installed tool/package version at the +execution boundary as the satisfiability adapter does; do not accept a +caller-authored version string. Python set/dict order, locale, wall-clock time, +process ids, and host paths never affect result identity. + +If a later profile genuinely needs an external timed, symbolic, probabilistic, +or partial-order tool, that is a separate tool decision. It must use +`tools/tool_versions.py` or an immutable archive/container digest, +checksum-verified acquisition, fixed list-form argv with no shell, empty or +allowlisted environment, no verification-time network, bounded CPU/memory/time +and output, safe stdout/stderr handling, and a canonical nox integration. It +must not inherit a model-check result from this untimed possibilistic lane. + +### Bind one exact model-check result + +The model-check evidence envelope is separate from the #961 bounded evidence +envelope and binds: + +- taxonomy revision and catalog digest, relation, profile, projection, and + claim coordinates; +- model id/revision, exact source and canonical model digests, and any + unauthenticated materializer assertions as such; +- checker configuration and digest; +- complete declared counts and exact explored counts; +- derived reachable possible-point carrier digest; +- outcome, safe counterexample or typed unsupported reason; +- mutation/agreement evidence refs and digests when retained; +- limitations, provenance scope, and explicit nonclaims; and +- replay data sufficient to recompute every join and result. + +The claim uses +`assurance_axis=model-check`, `assurance_status=model-checked`, and +`evidence_scope=model-check`. A passive profile uses `all-traces` for the +reachable exact finite model; an active profile uses `all-strategies` and its +evidence boundary additionally states that all reachable actual points and +traces under each declared strategy were explored. These universal words are +relative to the exact model/profile digest, never to every RAES runtime, +backend, policy, or future profile. + +A positive outcome should read as the SEM-231 property holding on the exact +complete finite model, not as RAES being opaque. A counterexample is still a +completed model-check result, but the evidence outcome—not the assurance +status—states that the model violates the relation. + +The catalog may advance its model-check axis only after the exact checked model, +negative mutations, replay, and independent reproduction are committed and +passing. Advancing the catalog requires a taxonomy revision and synchronized +updates to every live revision producer and fixture.

Model + input is bounded duplicate-rejecting UTF-8 JSON with an object root. There + is no YAML expression, Python import path, remote URL, `latest` alias, + caller-selected production corpus root, or environment-bound semantic + default. +2. **Closed schema and semantic gate.** The published schema, + `ContractModel`, canonical-order validators, graph-reference validators, + exact count/digest validators, and catalog/profile/claim join all pass before + exploration. Published JSON Schema and Python generation stay identical; + cross-field invariants remain Pydantic validators with + `x-raes-invariants`, not duplicated ad hoc checks. +3. **Finite-model and quantifier gate.** Initial states, transitions, + strategies, scheduler/environment pairs, order variants, evaluation cuts, + reachable fixed point, and declared/explored counts must agree. Unsupported + time, probability, concurrency, partial-order, coalition, or active + semantics fail closed until the checker configuration explicitly supports + them. No partial run can enter the model-check evidence state. +4. **Authentication and authorization boundary.** The intended checker is a + local read-only processor and crosses no HTTP, RUN-319, API-407, runtime, or + backend authorization surface. It therefore makes no authentication, + enforcement, or realization claim. Any future HTTP exposure must reuse + `create_control_plane_app()`, `ControlPlaneSecurityConfig.strict_defaults()`, + verified identity/role/target binding, request-size guards, + fingerprint/idempotency, and audit; no unauthenticated analysis route is + added. +5. **Secret-handling gate.** Profiles, model fixtures, counterexamples, + diagnostics, evidence, logs, and CI artifacts contain only synthetic bounded + values, safe ordinals/refs, counts, and digests. Raw possible worlds, secret + values, observation content, memory, policy/supervisor internals, + credentials, environment dumps, and host/native objects are excluded. + Hashing secret-bearing content does not make it a safe portable identifier. +6. **Diagnostic and error-envelope gate.** Expected non-positive results are + typed values with stable codes, schema-derived addresses, and bounded + generic messages. Never concatenate `str(exc)`, Pydantic `input_value`, + rejected keys/ids, tracebacks, stdout/stderr, or model contents into + diagnostics, CLI stderr, logs, audit, or evidence. A future HTTP wrapper + retains the incumbent `{"detail":"internal server error"}` envelope. +7. **Artifact and persistence gate.** Validate the complete evidence, claim, + counterexample, and redaction posture before serialization. If archived, + use safe root-confined names and atomic writes. Do not put the result in + `RuntimeSnapshot.metadata`, `AuditEvent`, operation details, + `BackendConformanceReport`, a mutable database, or a new evidence service. +8. **CLI, environment, and OS/process gate.** The default in-process checker + needs no secret loader, dotenv, subprocess, shell, socket, network, daemon, + privilege, or native backend. Model/profile contents, secrets, witnesses, + credentials, and complete results never enter argv, environment variables, + filenames, shell history, or host logs. An optional existing CLI command + passes only a neutral input path and governed profile id and emits validated + JSON; the portable source id comes from validated content rather than an + absolute or sensitive host path, and failures remain value-free. +9. **Logging and observability gate.** Progress logs are not evidence. The + default service emits no model-state or transition logs; exact declared and + explored counts live in the validated evidence envelope. Unexpected + failures may be named by safe exception class at an outer boundary but never + include exception text or model content. +10. **Governance/publication gate.** Any new public model/evidence schema + updates the hand-governed schema, schema bundle, semantic invariants, + valid/invalid fixtures, publication entry/hash, validator routing, + packaging, and compatibility assessment together. A catalog assurance + change advances the taxonomy revision and every current producer. No + issue-local verification script bypasses the canonical workflow. + +## Whole-Repository Surfaces In Scope + +- **Normative and concept authority:** ADR-099, SEM-231, behavioral relation + catalog/reader-facing specification, relation profile, claim validation, and + assurance aggregates. +- **Portable contracts:** the existing opacity/profile primitives, a distinct + finite transition-model input and model-check evidence shape, schemas, + fixtures, invariants, publication records, and corpus packaging. +- **Processor:** participant-opacity admission, canonical explicit-state + traversal, shared opacity kernel, counterexample selection, evidence + assembly, replay, and optional existing CLI projection. +- **Verification:** graph closure/count/digest tests, all quantifier domains, + fixed-point completeness without depth truncation, #961 agreement, + single-fault mutations, vacuity/unsupported/operational boundaries, + permutation determinism, secret/error sanitization, replay drift, schema and + installed-corpus parity, claim-policy checks, docs, and canonical + verification. +- **Host/runtime:** local hermetic in-process execution, deterministic + pre-admission resource caps, no ambient credentials or network, and safe + artifact handling.

It is not a runtime rewrite of the +scenario model, an invisible evaluator setting, or a replacement for evidence. + +## Adjacent Primary Literature + +### Dynamic treatment regimes + +Murphy's +[Optimal Dynamic Treatment Regimes](https://doi.org/10.1111/1467-9868.00389) +(2003) defines a dynamic regime as a sequence of decision rules that tailors +treatment to changing observed status. The useful transfer is the +history-dependent treatment-regime shape: assigned policy, decision history, +and realized treatment path are all analysis-relevant. + +RAES does not adopt Murphy's estimator or potential-outcomes assumptions, and +the SCE-003 contracts do not establish causal identification. A study must +state its estimand and justify the assumptions needed by its chosen analysis. + +### Adaptive testing and measurement validity + +Weiss's +[Improving Measurement Quality and Efficiency with Adaptive Testing](https://doi.org/10.1177/014662168200600408) +(1982) makes adaptive-testing performance conditional on an item-response +model, item pool, selection strategy, and termination criteria. This is a +critical negative lesson for SCE-003: adapting from a score does not make that +score a validated difficulty or competence scale. + +RAES therefore records a policy-local ordering and binds both an exact +versioned and digest-bound measurement-source definition and the exact +evidence instance used at a decision cut. It does not implement item response +theory, calibrate an item bank, estimate ability, or infer competence. + +### Curriculum and treatment-path effects + +Bengio, Louradour, Collobert, and Weston's +[Curriculum Learning](https://doi.org/10.1145/1553374.1553380) (2009) +demonstrates that the selection and order of examples can change learning +dynamics and outcomes. The transfer is that a scaffolded or adaptive path is +received treatment, not a presentation-neutral detail. + +RAES records fixed, adaptive, and scaffolded allocations separately and +archives realized decisions and interventions. It does not claim curriculum +optimality, improved generalization, pedagogical benefit, or participant +learning from the fact that an intervention was selected or delivered. + +### Common random numbers in simulation experiments + +Heikes, Montgomery, and Rardin's +[Using Common Random Numbers in Simulation Experiments](https://doi.org/10.1177/003754977602700301) +(1976) treats reuse of a pseudo-random-number stream across alternatives as a +deliberate correlated experimental design with corresponding statistical +analysis. Combined with RAES's L'Ecuyer-derived stream coordinates, this means +a follow-up trial never inherits a stream merely because it descends from +another run. + +An intentional common-random-number comparison retains the governed +randomness namespace and unchanged semantic stream addresses and declares the +paired analysis. An independent comparison declares independent +randomization. Run lineage alone implies neither relationship. + +## Source-To-Design Mapping + +| Scrutiny question | Adopted SCE-003 obligation | Explicit limit | +| --- | --- | --- | +| What exactly adapts? | A sealed experiment policy selects only declared actions or proposes a separately admitted follow-up. | No live SDL, topology, factor, identity, snapshot, or stream mutation. | +| What was observed? | The policy names an exact source definition; each decision names an exact evidence instance and state cut. | Identity and provenance do not prove construct validity or calibration. | +| What treatment was received? | Fixed, adaptive, and scaffolded assignments and realized intervention paths are archived separately. | A deterministic path is not a causal effect estimate. | +| How is sequential choice controlled? | Rules, priority, evaluator identity, cadence, cooldown, bounds, stopping disposition, and history heads are predeclared. | The contract does not correct optional-stopping or path-selection bias for an analyst. | +| Can a harder scenario replace the baseline? | A changed scenario becomes a new admitted trial and run linked to the source. | Descent does not authorize identity or random-stream reuse. | +| Can stochastic alternatives be compared? | Random-stream identity and semantic addresses remain governed experiment facts. | Common versus independent randomization must be declared and analyzed accordingly. | +| Does replay establish validity? | Replay establishes the same bounded resolver decision for the same governed inputs. | It does not validate the measurement model, simulation model, backend, pedagogy, or policy optimality. | + +## Threats To Validity And Required Disclosures + +### Construct and measurement validity + +The study must identify the measurement definition, derivation method, +calibration or uncertainty basis, visibility, and known limitations. A +threshold over completion time, score, retry count, or objective progress is +not a universal competence measure. Substituting a different definition under +the same local source id fails contract validation, but semantic suitability +still requires domain evidence. + +### Endogenous and time-varying treatment + +An adaptive action depends on post-allocation observations. Naive analyses that +condition on the realized path or compare it as though it were a baseline +factor can introduce selection bias. The study must distinguish assigned +policy effects from per-decision, per-protocol, or descriptive path analyses +and state the assumptions used for any causal interpretation. + +### Sequential looks, stopping, and missingness + +Decision cadence, cooldown, intervention bounds, terminal rules, +path-dependent eligibility, denied/unsupported actions, and lost evidence can +change inclusion and stopping. These facts are archived so an analysis can +handle them; SCE-003 does not prescribe or certify a sequential estimator, +missing-data model, or multiplicity correction. + +### Scaffolding and information boundaries + +Guidance availability, delivery, participant observation, and downstream use +are separate events. Hidden or assurance-only evidence remains subject to +participant information-flow rules. A policy decision neither authorizes +disclosure nor proves that a participant received or used a scaffold. + +### Simulation dependence and V&V + +Paired/common and independent randomization answer different variance and +comparison questions. The analysis plan must name the relationship. It must +also state the simulation/backend validity evidence and intended-use boundary; +deterministic policy execution cannot compensate for an invalid scenario, +apparatus, observation model, or backend realization. + +## Engineering Finding From This Audit + +The initial SCE-003 implementation bound observation inputs to a local +`source_id` and carried an exact evidence reference, but did not require the +input to repeat and match the policy's immutable source-definition identity. +That permitted measurement substitution under the same local role. + +The corrected contract: + +1. models the source definition as an `ExperimentReferenceModel` specialization + that requires both `ref_version` and `ref_digest` and forbids `ref_path`; +2. carries that source definition in transient inputs and archival observation + references, separately from the exact evidence instance; +3. rejects source-definition mismatch in the pure resolver; +4. rejects substituted source definitions during run-provenance validation; + and +5. publishes the same constraints in JSON Schema and tests model, resolver, + archive, and schema failure modes. + +This closes an identity and reproducibility gap. It still intentionally leaves +measurement construction and causal/statistical adequacy to evidence-bearing +study design and review. + +## Minimum Defensible Analysis Record + +A claim-bearing adaptive study should disclose: + +1. assigned condition and exact policy identity; +2. policy-local difficulty ordering and rationale; +3. measurement definition, evidence derivation, uncertainty, and limitations; +4. exact observation and decision cuts; +5. realized intervention path, including denied, unsupported, failed, or + missing interventions; +6. cadence, cooldown, stopping, and follow-up eligibility rules; +7. random-stream relationship across compared alternatives; +8. estimand and treatment-path handling; +9. missing-data, censoring, multiplicity, and sequential-analysis treatment; + and +10. simulation/model/backend V&V scope and explicit nonclaims. + +The portable contracts preserve the inputs needed to audit such a record. They +do not make every analysis using those inputs defensible. + +## Source And Notice Disposition + +The publications above are semantic design precedents. SCE-003 adopts no +source syntax, schema, code, estimator, item-response model, curriculum +optimizer, random-number algorithm, controller implementation, or wire +format. No compatibility or copied-code claim is made, no third-party notice is +introduced, and the normative `sdl-lineage-ledger-v1` subject/notice +disposition is unchanged because SCE-003 adds experiment-core contracts rather +than SDL subject derivations. + +## References + +- Susan A.
