Summary

  • retain bounded pure Core let bindings as generic, source-ordered Target IR
  • bind pure results to compiler-produced projections that an independent verifier can reconstruct
  • select only compiled-Core-relevant adapter configurations for executable profiles
  • preserve explicit imported Nominal<T> contracts without changing their storage ABI
  • extend the checked ABI and provider-contract fixture without adding application vocabulary

Plain-English Walkthrough

TL;DR

Edict previously rejected a bounded pure Core program as soon as it encountered
a let, even though the expression was already typed and bounded. This change
preserves those expressions as generic Target IR data under the exact
source-Core semantic closure, then emits a compiler-owned result projection
that identifies the retained binding. [claim:pure-core-lowering,
confidence:1.00]

The result is a new honest compiler boundary: pure application programs can
reach a provider as verified generic artifacts, while the provider remains
responsible for declaring which Target IR, adapter, configuration, and
projection schemas it accepts. This PR does not add an evaluator to Echo and
does not claim end-to-end application execution. [claim:provider-boundary,
confidence:1.00]

Walkthrough

Before this change, the compiler treated CoreNode::Let as an unsupported
target node. The lowerer now first validates the Core local graph, rejecting
duplicate binders and undeclared, conflicting, forward, or self-referential
local use before emitting any artifact. It then copies each pure binding into
Target IR in source order with a deterministic compiler-owned ID.
[claim:validated-binding-graph, confidence:1.00]

The flow is intentionally generic:

flowchart TD
    A[Checked bounded Core] --> B[Validate local graph]
    B --> C[Source-ordered pure bindings]
    C --> D[Digest-bound Target IR]
    D --> E[Compiler result projection]
    E --> F[Independent projection verification]
    F --> G[Provider admission]
Loading
Caption: Pure Core crosses the compiler-provider boundary as data
  1. Edict starts from checked Core with bounded types and budgets.
  2. Local identities and reference order are validated before lowering.
  3. Pure expressions remain generic Core expressions inside Target IR; they are not evaluated or rewritten into application-specific instructions.
  4. The semantic closure binds the artifact to the exact source Core and imported lawpacks.
  5. The projection names exact compiler-produced bindings, and a structurally separate verifier reconstructs that relationship.
  6. The provider still decides whether its declared contract admits the resulting artifact family.

This keeps ownership straight: Edict retains authored pure meaning, its
compiler proves the mapping, and a downstream provider may accept or refuse the
generic artifact. No runtime gains application nouns or callbacks.

The projection verifier compares binding count, order, deterministic ID, exact
local identity, and exact expression against Core. Missing, substituted,
reordered, or duplicate binding authority rejects as CoreTargetMismatch
through both projection emission and independent verification; editing only
Target IR or only the projection cannot make the mutation authoritative.
[claim:independent-projection-verification, confidence:1.00]

Application assembly now obtains an effect-free adapter's exact target
configuration from its operation profile. Selection follows only adapter
operation profiles whose generic Core mapping is required by the compiled
application; unused profiles with unrelated configurations neither enter
provider inputs nor create false ambiguity. Previously, the build path only
inspected effect-owned configurations and failed before provider invocation
when a pure executable profile had no effects. The provider-boundary witness
checks the emitted request input's role, kind, coordinate, domain, digest, and
bytes. [claim:effect-free-configuration, confidence:1.00]

Compatibility and limits

  • Existing intents omit pureBindings when the list is empty, preserving their prior canonical shape.
  • Pure programs now require a semantic closure even when they have no explicit basis or imports, because their retained expressions are executable meaning.
  • The provider-contract fixture changes because the Target IR and result-projection schemas gain new optional variants.
  • Imported nominal contracts are deliberate and generic: exact contract equality precedes structural representation compatibility.
  • Structured loops remain unsupported; this PR only admits bounded pure let bindings already present in checked Core.
  • The real Jedit consumer now produces a compiler-generated generic package and an accepted independent-verifier report through Echo #724. That proves package construction and verification only; Echo still does not evaluate the program or settle a Tick. [claim:first-consumer-routing, confidence:1.00]

RED/GREEN evidence

The original implementation RED was observed with focused tests before the
compiler and schema changes:

  • cargo test -p edict-syntax --test target_ir pure_core_bindings_lower_as_generic_target_program -- --exact
  • cargo test -p edict-syntax --test target_ir malformed_pure_binding_graphs_reject_before_target_artifact -- --exact
  • cargo test -p edict-syntax --test result_projection pure_binding_projection_rejects_missing_substituted_and_reordered_target_authority -- --exact
  • cargo test -p edict-cli application_build::tests::operation_profile_configuration_is_selected_when_adapter_has_no_effects -- --exact
  • cargo test -p edict-cli application_build::tests::unused_operation_profile_configuration_does_not_enter_application_selection -- --exact

The review-repair invariants were mutation-calibrated RED. Temporarily inverting the effect-free fixture assertion made its focused test fail only at that assertion. Before the selected-profile repair, the conflicting-unused-profile regression failed with InvalidLawpackAdapter; after selection was scoped to compiled Core requirements, both it and the public external-action application build passed.

Exact-head GREEN verification at
39a796de04b3400f569880da06878da50d8ed0ee:

  • cargo xtask verify
  • cargo test -p edict-cli operation_profile_configuration_is_selected_when_adapter_has_no_effects
  • cargo test -p edict-provider-schema --test provider_contract_pack target_ir_root_accepts_only_closed_nonempty_pure_bindings
  • cargo test -p edict-syntax --test result_projection pure_binding_projection_rejects_missing_substituted_reordered_and_duplicate_target_authority
  • cargo xtask target-ir-goldens --check
  • cargo xtask lawpack-goldens --check
  • cargo xtask provider-contract-pack --check
  • git diff --check

Documentation impact

Updated the Target IR, result-projection, and lawpack topic shelves and their
executable test plans. Updated both public CDDL fragments and regenerated the
checked provider-contract pack. The review repair adds the missing schema and
provider-boundary evidence mappings without changing exported contract bytes.

Dependency impact

None. No dependency was added or changed.

Estimated code review effort: 5 (Critical) | ~100 minutes

Merge Risk: 🟡 Moderate · up to 986c3

This PR broadens bounded pure Core compilation into generic Target IR, but the current head still has correctness and contract gaps that can produce invalid or unverifiable artifacts, including conflicting bindings, unreconstructible imported byte intervals, and acceptance of invalid string metadata. Merge should wait for these issues to be fixed or explicitly accepted.

In `@crates/edict-cli/src/application_build.rs`:
- Around line 3208-3223: Extend
operation_profile_configuration_is_selected_when_adapter_has_no_effects in
crates/edict-cli/src/application_build.rs (3208-3223) beyond
single_configuration and the ID check: assert the emitted
05-target-configuration semantic input, complete identity including digest and
bytes, and provider invocation. Update docs/topics/lawpacks/test-plan.md (89-89)
so LAWPACKS-TP-016 records these provider-boundary assertions as its oracle and
evidence.

In `@crates/edict-provider-schema/tests/provider_contract_pack.rs`:
- Around line 311-341: Update the Target IR fixture used by
target_ir_root_accepts_only_closed_nonempty_pure_bindings, specifically
representative_target_ir, to omit basis from the intent before removing
semanticClosure. This ensures the validation failure isolates the closure
requirement while retaining the existing empty pure-binding ID assertion
unchanged.

In `@crates/edict-syntax/tests/result_projection.rs`:
- Around line 277-323: Extend
pure_binding_projection_rejects_missing_substituted_and_reordered_target_authority
to mutate duplicate binding IDs or local references, and run every mutated
artifact through verify_result_projection, asserting stable failure kinds. In
crates/edict-syntax/tests/result_projection.rs lines 277-323, add executable
coverage for duplicate and independent-verification rejection. In
docs/topics/result-projections/test-plan.md lines 23 and 61, retain implemented
status and update evidence to list all covered rejection cases.

In `@docs/topics/target-ir/test-plan.md`:
- Around line 113-114: Update the test-plan evidence map to cover the published
target-ir-pure-binding schema rule and
target_ir_root_accepts_only_closed_nonempty_pure_bindings test, either by
extending TIR-TP-029 or adding a dedicated schema-fidelity case. Ensure the
entry links the CDDL rule and executable schema test and covers
closed-versus-legacy root separation plus the nonempty binding-id constraint,
while preserving the existing TIR-TP-036 and TIR-TP-037 coverage.

Assert the effect-free precondition.

single_configuration merges configurations from adapter.effects() and operation profiles. The fixture currently has no semantic effects, but this test does not enforce that invariant. An effect with the same configuration could make the test pass without proving profile-owned selection.

Add an empty-effects assertion before calling single_configuration to keep LAWPACKS-TP-016 accurate.

Do not reject unused profile configurations. [claim:configuration-scope, confidence:high] Adapter validation does not require profile configurations to match, but validate_target_configuration_binding collects every profile reference before Core compilation. A valid adapter with one unused profile using a different configuration therefore fails with InvalidLawpackAdapter. Scope collection to compiled-Core references, or enforce adapter-wide uniqueness.

Item Source Severity File Commit Outcome
Pin the effect-free precondition in the profile-owned configuration witness PR global review P3 crates/edict-cli/src/application_build.rs 65e893fe Added explicit zero-effects evidence; mutation-calibrated RED; focused and full verification GREEN.
Exclude unused adapter-profile configurations from application selection PR global review P2 crates/edict-cli/src/application_build.rs adc1bf6d Reproduced InvalidLawpackAdapter; scoped selection to adapter profiles whose Core mapping is required by compiled Core; threaded the selected configuration through lowering and verification; focused, public-build, and full verification GREEN.
Record the selected-profile configuration contract PR global review P2 CHANGELOG.md, docs/topics/lawpacks/test-plan.md adc1bf6d Added LAWPACKS-TP-017 and branch-accurate compatibility wording.

RED for the second finding was deterministic: unused_operation_profile_configuration_does_not_enter_application_selection failed under the prior all-profile selection with InvalidLawpackAdapter. GREEN includes that regression, the existing effect-free provider-input witness, the real public external-action application build, and complete cargo xtask verify.

Deep self-audit found no additional actionable P0-P5 correctness, determinism, architecture, typing, schema, documentation, or style defects. The four existing inline review threads remain resolved; both repair findings were global/outside-diff findings without resolvable inline threads.

Operational note: an assertion failure in the first automated PR-description transformation briefly submitted an empty body. The complete prior body was recovered from GitHub userContentEdits, amended with the exact-head evidence, and re-published. Verification confirms a 9,210-character body containing Closes #200, exact head adc1bf6d…, and the selected-profile repair. No code, commit history, review, or branch state was lost or rewritten.

Both repair commits are signed by James Ross <james@flyingrobots.dev>. No amend, rebase, force operation, merge, review dismissal, or unrelated GitHub mutation was performed.

Support non-exact byte intervals in imported type definitions.

bytes_type_coord emits Bytes<min=N,max=M> when bounds differ. This parser accepts only Bytes<max=N> and Bytes<exact=N>. Therefore, an imported fact such as Nominal<Bytes<min=4,max=8>> fails with an unsupported imported definition.

Parse the min=...,max=... form and add a deterministic imported-type test.

**/*

📄 CodeRabbit inference engine (AGENTS.md)

**/*: Never amend Git commits, use git rebase without explicit user approval, or force any Git operation; use new commits and regular merge commits instead.
Do not create draft pull requests, and never use a codex prefix in branch names, pull request titles, or commit messages.
Pull requests for issue work must include GitHub auto-close text such as Closes #123`` for every issue they intend to close.
Use codex-think --remember --json when starting a session, entering the repository, or regaining context, and record significant durable events with `codex-think "..." --json`. Treat Think as memory rather than repository truth.
Every pull request body must contain `## Plain-English Walkthrough` with `### TL;DR` and `### Walkthrough`, explaining the prior behavior, new model and dataflow, invariants, failures, compatibility, and verification as applicable.
Use Mermaid diagrams for nontrivial flow, lifecycle, ownership, or component interaction when clearer than prose; every diagram requires an introductory paragraph, the diagram, the exact collapsed caption structure, and a concluding interpretation.
Tag each material technical claim at first occurrence as `[claim:, confidence:]`, cite evidence using repository-relative paths, line numbers, and Git SHAs, and end the explanatory body with a collapsed citations appendix.
If CodeRabbit is actively reviewing, obtain its approval before merge; if unavailable due to limits or credits, request `@codex review please` and wait for the alternate response. Do not treat unavailability as approval unless a maintainer explicitly overrides the gate.
For release preparation, write the release thesis first, reconcile changes from the previous tag, update release policy and tests, verify the milestone has no open issues and no unauthorized crates.io publication occurred, and record a durable release report.
Run `cargo xtask verify` before claiming a branch is ready.

Finding Severity Repair Commit Outcome
Dangling Core result references could reach Target IR P2 Validate final result references before artifact emission 3904c0a8 Closed
Pure binding values could disagree with declared types P2 Validate constants, records, fields, conditionals, supported intrinsics, and local types 3904c0a8 Closed

Verification at this head before push:

  • cargo xtask verify: PASS
  • all-feature Clippy with warnings denied: PASS
  • complete workspace tests and doc tests: PASS
  • canonical goldens, provider fixtures, contract graph, and build: PASS
  • git diff --check: PASS

Review-level addendum at exact head 15bdab4f:

Finding Calibration Repair Commit
Distinct Target IR binding records could share one compiler-local identity RED reproduced: canonical encoding succeeded Canonical encoder now rejects empty or duplicate local identities independently of target binding IDs 15bdab4f
Imported Nominal<Bytes<min=N,max=M>> could not round-trip through compiler facts RED reproduced: UnresolvedType Imported byte-definition parsing now preserves max-only, exact, and validated min/max intervals 2fec8e0a
Effect-free profile-selection test lacked its precondition Already resolved before this checkpoint Existing test explicitly asserts adapter.effects().is_empty() and validates the complete provider semantic input pre-existing

Both new REDs are permanent regressions. cargo xtask verify passes again at the new head. Awaiting fresh exact-head CI and review; no merge or review dismissal occurred.

- Around line 3367-3381: Extend
public_application_selects_configuration_from_compiled_core_profiles with a
negative case that repins targetConfiguration to
unused-profile-configuration.cbor, rebuilds, and asserts
TargetConfigurationMismatch plus absence of published output artifacts;
alternatively narrow the test name to its compile-and-bind coverage, since
externalAction stops before provider invocation.

In `@crates/edict-syntax/src/target_ir.rs`:
- Around line 540-552: Update validate_pure_binding_graphs to remove
CoreNode::Branch from the exclusion predicate, so intents containing Branch
reach validate_pure_binding_graph and are checked before lowering rejects them;
continue excluding CoreNode::For as before.
- Around line 810-843: Update core_value_fits_declared_type so CoreValue::String
matches CoreType::String only when canonical is "raw-utf8", while preserving the
existing maximum-length validation. This ensures externally constructed Core and
core.string.concat reject non-raw-UTF8 string constants consistently.

In `@crates/edict-syntax/tests/target_ir.rs`:
- Around line 1229-1271: Strengthen both rejection tests by asserting the
structured failure fields in addition to the existing status, artifact, and kind
checks: the dangling result failure should identify the intent and have
node_index None, while
type_incompatible_pure_binding_rejects_before_target_artifact should identify
the intent and have node_index Some(0). Do not assert detail prose.

projection_rejects_local_identity_shared_with_application_input proves emission only.

The test asserts CoreTargetMismatch from emit_result_projection. It never calls verify_result_projection. The shared-identity guard lives in the seeding of claimed_local_ids at crates/edict-syntax/src/result_projection.rs Line 564, which resolve_projection_sources runs for both paths. Emission coverage alone does not prove the independent verifier rejects a colliding identity.

The independent verifier is the boundary the application build depends on at crates/edict-cli/src/application_build.rs Line 359. Every other pure-binding authority mutation in this file routes through assert_pure_binding_authority_rejection, which checks emission and verification. This test bypasses that helper.

Emit the projection from the unmutated pair first, then apply the arg.0 collision, then assert verify_result_projection rejects the original canonical bytes and digest against the mutated pair. Reuse assert_pure_binding_authority_rejection if its mutation hook accepts a Core-side change.

One further note on precision: Line 332 mutates intent.body.locals[1] by index. If local ordering moves, the test still rejects, but for a different reason than its name states.

As per coding guidelines, "Tests must assert software behavior and stable error kinds or structured artifacts".

Fresh-review closure at exact head 12febd2f:

  • 920e88cb enforces raw-utf8 for direct Core string constants, adds a calibrated RED/GREEN regression, distinguishes result-vs-node failures by structured intent and node_index, and lets Branch graphs reach validation before their existing unsupported-node rejection.
  • 12febd2f adds the negative public-build witness: substituting the unused profile configuration yields TargetConfigurationMismatch and publishes no output.
  • Owning Target IR and lawpack test-plan evidence was updated.
  • cargo xtask verify passes at the published content: formatting, warnings-denied Clippy, complete workspace and doc tests, goldens, provider fixtures, contract graph, and build.

The four corresponding threads are resolved. No review was dismissed and no merge occurred. Awaiting the new exact-head CI and CodeRabbit verdict.

@codex review please

Correct exact-head request: review Edict PR #201 at 12febd2fbdbc37f5b3c8c76feb02d9594cbe9afc against origin/main. The earlier mention was edited after creation, so this new comment ensures the automation receives the verified SHA. Audit the full diff and the recently closed Core graph/type, Target IR local identity, imported byte interval, string canonicality, and public profile-configuration boundaries.

P2 Badge Validate conditional predicate operand types

When caller-supplied Core contains a pure if, this branch checks only whether the predicate's local references are available; it never checks that comparison operands have compatible types or that integer constants fit their declared widths. For example, an equality comparison between a Bool and U64 with otherwise valid branches is accepted and emitted as typed Target IR. Validate predicate types before returning Lowered, using a structured failure for malformed Core.

P2 Badge Reject local identities shared with steps and requests

For a caller-constructed TargetIrArtifact, this new set contains only pure-binding locals, so encode_target_ir_artifact still accepts a pure binding whose local id is also produced by a target step or external-action request. The resulting canonical artifact has two producers for one local, making result references ambiguous to consumers. Fresh evidence after the earlier thread is that the subsequently added local_ids check is populated exclusively inside the pure-binding loop; include all producer classes in this uniqueness check.

P2 Badge Recognize every Core integer width

When valid caller-supplied Core uses a bare built-in I8, I16, U8, or U16 type reference without redundantly adding that built-in to core.types, resolved_core_type returns None, so the new binding/result type validation rejects it as InvalidCoreIdentity. These four widths are part of the published Core ABI in docs/abi/edict-core.cddl and are already accepted by parse_core_integer; add them to this built-in match so Target lowering does not reject valid Core solely because it uses a narrower integer.

P1 Badge Enforce the lower bound of exact byte constants

When an inline lawpack helper declares a Bytes<exact=N> result or binding, this conversion reduces the contract to only N as a maximum, and the caller at validate_core_value checks only value.len() <= max. A one-byte constant therefore validates under Bytes<exact=32>, after which compilation and Target IR trust the value as exactly 32 bytes. Preserve both interval bounds here and require min <= len <= max; the same interval handling should also recognize imported Bytes<min=M,max=N> definitions.

P2 Badge Retain helper-only return types in Core

When a pure helper returns an exported non-primitive type that is not otherwise mentioned by a source parameter, output, or annotation, the compiler can still emit an inferred let local with that type, but it never inserts the helper-return shape into core.types. This new call validation then requires resolved_core_type(core, expected) to succeed, so compiler-produced Core such as an unused helper-only binding compiles successfully but is rejected during Target lowering as InvalidCoreIdentity. Add every used helper signature shape to the emitted Core type closure rather than requiring source code to mention the type redundantly.
