Why this plan exists + +The prior ProjectMemoryAuthority redesign (~20 untracked files: `authority-*.ts`, `destruction-guard.ts`, `project/identity.ts`, `project/reference-adapter.ts`, ADR-0004, CONTEXT update, ~4 authority test files, crash-harness fixtures) plus the 1A keystone/harness fixes lived **only as uncommitted working-tree state** in a `/private/tmp` worktree. `/private/tmp` was cleaned; `git fsck` found no dangling objects and the branch was never pushed, so that work is **gone**. Recoverable: the committed baseline `d7b011738` ("fix(opencode): make project memory process safe") — the Iteration-1 process-safe memory foundation. This plan reconstructs the lost redesign **faithfully** (from the approved ADR-0004 / CONTEXT / redesign-decision spec, retained in design memory) on top of that baseline, phased so each stage is independently committable. + +## 1. Baseline at `d7b011738` (surveyed — what exists, all tests GREEN) + +**Modules** (`packages/opencode/src/memory/`): +- `home.ts` MemoryHome — paths only: `directory/topics/manifest/generations` + shared `locks` dir. No policy/retirements/aliases paths yet. +- `store.ts` MemoryStore — generation+manifest persistence. **Topics are versioned** (revision int, named generation, atomic temp→rename→manifest). **Policy is NOT in the Home** — it lives in worktree/global `.opencode/memory.jsonc|json` via MemoryConfig, no generation/revision/CAS. `commit(expectedRevision)` CAS exists but is **unused in src/**; `updateTopics` (hides revision bump) is the live writer.

Decide: (a) Policy-in-Home + supersede ADR-0001 (controller-owned, atomic, not user-editable in place), or (b) keep Policy in `.opencode/memory.jsonc` (user-editable, NOT versioned/CAS'd) and P1 collapses to Topics-only atomicity. **Also**: how is GLOBAL Policy represented (it spans projects; no per-project Home)? +- **D2 — Source-Home preserve + retention (P3/P6/P7).** "Source Home preserved, non-authoritative" introduces a NEW class of non-authoritative artifact; ADR-0001/0002 require a "separate Project Memory retention policy" BEFORE any such artifact may exist. Decide: (a) define the retention/GC policy for retired-identity Homes in the recreated ADR-0004, or (b) revert to baseline migrate-then-remove (source deleted) — then the 3 "source Home deleted" assertions stay and P6/P7 preserve-assertions drop. +- **D3 — Retirement-as-merge / alias-lineage (P3).** "Old ID routes to successor" + immutable `recordAlias` tombstone + `canonical()` alias-chain + deterministic-union merge of two Projects' Memory+identity+FK is, in substance, the two **explicitly-forbidden** decisions (Project Merge, ProjectLineageID) relabeled. Decide: (a) approve a lineage/merge system with the exact merge rules + alias permanence, or (b) collapse to migrate-and-retire with conflict-fail-closed (closer to ADR-0001). +- **D4 — New public surface to confirm** (not in any recoverable spec): (i) the 6-phase forward-only journal machine `Requested→TargetPrepared→IdentityPublished→ReferencesRetired→CleanupPending→Completed` (ADR-0002 only states a single ordering invariant); (ii) the opaque Revision fingerprint composition ("canonical identity + Topics revision + Policy fingerprint + topology fingerprint + admission fingerprint" — topology/admission fingerprints are undefined); (iii) the `changeMemory` data-Change algebra (`replace_topics|mark_matched|set_policy`) replacing the baseline callback `updateTopics`. + +**⇒ NEW PHASE P0 (mandatory, before P1):** Recreate `packages/opencode/src/memory/docs/adr/0004-project-memory-authority.md` + the CONTEXT authority-glossary update **as a written, committed design-of-record** that resolves D1–D4 explicitly.

State machine: `Requested → TargetPrepared → IdentityPublished → ReferencesRetired → CleanupPending → Completed`. **D4.** It rejects a successor that is itself retired or belongs to an independent Project. **It is Identity Retirement, not the explicitly-deferred Project Merge**: exactly one logical Project's old identity converges into its new identity, preserving one Memory (no fork).

Order preserves the rolling-upgrade key order used by supported older processes (no ABBA). Recovery completes before any routine Project lock; routine never goes Project → ledger. + +### Atomic Topics + Policy + revision (**D1**) +Project Memory Topics, Project configuration (Policy), topology, and admission inputs contribute to **one** opaque `Revision`. **Policy lives in the Memory Home** generation (`policy.jsonc` co-tenant with topic YAML); the Home generation is the single atomic publish point (temp-dir → rename → manifest). Worktree `.opencode/memory.jsonc|.json` and the global config are **admission candidates only**, not authorities. *(Supersedes ADR-0001's "Policy resolved from the primary directory so it stays user-editable": under this ADR the controller owns Policy, atomically versioned with Topics. Global config remains a fallback candidate admitted when no Home Policy exists.)* Reads are pure; normalization never writes. + +### Worktree lifecycle (integration via an internal guard) +Worktree reset/remove remain the Worktree authority's operations, integrated through an internal, non-exported `ProjectMemoryDestructionGuard` whose sealed durable intent binds `{request_id, requested_project, identity_revision, normalized_target, action, topology_fingerprint, candidate_fingerprint}`. Every execution/recovery first joins Identity Retirement and re-resolves the requested Project; an identity-revision change rebases the intent and rescans before publication. The guard publishes valid candidates into the authoritative generation before invoking the one fixed action adapter, so action failure leaves only safe legacy duplicates. Destructive admission **never** trusts a process-local success cache — it rescans the Project primary + every registered worktree each time. + +### Automatic Identity Retirement +Limited to **verifiable first identity convergence**: source = the observed repository's root commit; the repo-local cache names it `previous`; current resolution selects the successor from the remote identity; every existing successor directory re-resolves to that successor (different physical stores allowed — one remote Project may have several clones). A remote X→Y change, contradictory observation, or unavailable evidence **fails closed** and does not become an implicit Project Merge. + +### Crash semantics +Commit point = the immutable tombstone. Pre-tombstone: source authoritative. Post-tombstone: successor authoritative, old revisions invalid; recovery rebuilds target from the latest two-sided state if either side changed after `TargetPrepared`. Each public command first joins/recovers touched journals. Source Home is preserved (non-authoritative) and is never read as an authority after the tombstone. + +## Decisions D1–D4 (resolved) +- **D1 — Policy in Home generation**, atomic with Topics, one Revision; worktree/global config = admission candidates. *(Supersedes ADR-0001's primary-directory Policy.)* +- **D2 — Source Home preserved**, non-authoritative; old ID routes to successor via alias. GC/retention is **excluded** this round; retired Homes remain as backups indefinitely. *(ADR-0001/0002's retention precondition is satisfied by "retain indefinitely; GC deferred" — no non-authoritative artifact is ever silently collected.)* +- **D3 — Identity Retirement approved**: old ID retires into successor; immutable alias tombstone + canonical chain + deterministic-union into ONE Memory (no fork). Distinct from the forbidden Project Merge. +- **D4 — Surface confirmed**: 6-phase forward-only journal; opaque Revision fingerprint (identity + Topics revision + Policy + topology + admission); `changeMemory` Change algebra. + +## Consequences +- `MemoryLock` (public), alias mutation, manual admission invalidation, project-directory configuration writes, and callback-shaped identity migration are **removed from application callers**; they survive only as authority-private adapters. +- Crashes across filesystem and SQLite are recovered by **advancing** the recorded retirement state; no cross-store rollback is promised. +- The source Home may temporarily remain after identity publication; it is non-authoritative and cannot be recreated through the retired ID. +- An immutable `ProjectLineageID` could remove identity movement entirely but needs a new product identity, schema backfill, rolling-upgrade protocol, and explicit Project Merge semantics — **deferred** to a separate proposal. +- Per AGENTS §7 review: the legacy `inspectHome` allow-list (`memory/identity-migration.ts:43-54`) must either be extended to the new Home contents (policy.jsonc) or the legacy path is retired when the P6 cutover lands — it must not fail-closed on a modern Home.

Memory activates normally once the repository gains a real identity; migrating the shared bucket is structurally infeasible (no per-repo provenance) and pre-existing orphans belong to the deferred retention/GC decision. - Red: search must report "unavailable" and /memory on must stay off for a commit-less repo even with an enabled global config and seeded topics - Green: single guard; identity-scoped (repos with a commit activate normally) - Mutation: removing the guard turns both Red tests red again - Domain regression: memory+project suites 162 pass / 0 fail; opencode+core typecheck clean - redo plan: record Fix #5 decision; reopen #3 (ABBA reachable via remote→remote identity change, MEM-PR01-R1-24) - remove leftover no-assertion diagnostic scaffold (repro-scope-finding); its scenario is captured in finding MEM-PR01-R1-06 for the M-C slice Co-Authored-By: Claude --- docs/memory-authority-redo-plan-2026-08-12.md | 5 +- packages/opencode/src/memory/memory.ts | 7 + .../memory/memory-global-identity.test.ts | 235 ++++++++++++++++++ 3 files changed, 246 insertions(+), 1 deletion(-) create mode 100644 packages/opencode/test/memory/memory-global-identity.test.ts diff --git a/docs/memory-authority-redo-plan-2026-08-12.md b/docs/memory-authority-redo-plan-2026-08-12.md index 898ec05649..ab4277273f 100644 --- a/docs/memory-authority-redo-plan-2026-08-12.md +++ b/docs/memory-authority-redo-plan-2026-08-12.md @@ -190,8 +190,11 @@ After the survey + ultracode adversarial review, the user applied Occam's Razor |---|---|---|---| | **#1** Repoint `workflow`+`permission` FK on identity upgrade (was `ON DELETE CASCADE` silent data loss) | MEM-REF-07 | ✅ done (mutation-proven) | `ec6972b22` | | **#2** Remove `.orDie` on the migration seam (`memory/identity-migration.ts` via `project/identity-migration.ts:19`); propagate `ConflictError`/`InvalidHomeError` as typed errors to the instance-store Deferred + HTTP project handler boundary | typed-error invariant (#5) | ⏸ **deferred** — full typed-propagation is a multi-file cascade (seam→migrateProjectId→fromDirectory Interface→instance-store load/reload/Deferred→HTTP) for a marginal gain (HTTP 409 vs 500 on a rare migration conflict; `.orDie` already preserves `ConflictError` in the Die cause, so it stays diagnosable).

R1-12 inspectHome wedged every upgrade after a crash: the store's own atomicWrite residue (manifest.json...tmp) was rejected as foreign state. Tolerate the store's own temp pattern; foreign files still fail closed (pinned). R1-15 The merge compared full topic JSON, so controller metadata drift from MemoryStore.markMatched (last_matched_at/match_count/revision/ updated_at) registered as a user-visible ConflictError and wedged the upgrade. Compare content only; the target's own copy stays authoritative; real content differences still conflict (pinned). R1-11 Permission FK repoint used a bulk UPDATE that violated the unique (project_id, action, resource) index whenever the successor identity already held the same (action, resource) — the immediate transaction died and the whole upgrade wedged on every retry. Repoint per row; on collision the successor row wins and the duplicate old row is dropped; disjoint rows still repoint. R1-24 The redo plan claimed ABBA unreachable because retirement was "one-way" — false: a changed origin URL yields remote→remote transitions, and the old lock structure (hold flock(old) across the merge while updateTopics locks flock(new) inside) deadlocks opposite-direction migrations (Red: 20 s test timeout on the legacy structure). Sorted pre-acquisition is impossible because the flock is non-reentrant, so fix by construction: a sorted pair lock serializes the two directions and the merge is restructured into three phases that never hold more than one memory-project:* lock at a time. A source that changed mid-merge now fails closed with retryable SourceChangedError instead of risking deletion of new data. Crash-retry convergence pinned (R1-13). - Domain regression: memory+project suites 169 pass / 0 fail; opencode+core typecheck clean; lint ratchet unchanged (0 new warnings).

charset=UTF-8 Content-Transfer-Encoding: 8bit R1-16 (blocking): list() ran `git worktree prune` and deregistered sandboxes for every merely-prunable entry. "prunable" does not prove a worktree is gone — git also marks inaccessible directories (unmounted volume, locked parent) and broken gitdir links whose directories still exist, so a read call could destroy git admin data and live registrations. list() is now a pure observation path: prunable entries stay hidden from the listing but are otherwise untouched. The destructive cleanup moves to the action path, where each case can be proven: - remove() gains a prunable branch: reconcile legacy memory fail-closed, prune the admin data, remove the directory if it still exists, delete the branch, drop the registration. - remove() gains a git-unknown recovery branch (R1-18): a registered worktree with no git record previously failed forever with a false "not registered" error and no remediation; it now reconciles legacy memory fail-closed and drops the stale registration without ever deleting the directory. - Registration cleanup drops every canonically-equal entry, not just the first — symlinked paths (/var vs /private/var) could register the same worktree twice and leave a zombie entry that broke serialized removal. Pins (both mutation-proven): - R1-17: reset fails closed over invalid legacy memory and preserves it. - R1-19 (blocking): reset/remove invalidate the admission cache before the rescan; a reset-primed clean cache must never hide a legacy file that appears before a later destructive operation. - Updated the prune-era list test to the new semantics (list hides but does not touch; explicit remove cleans up). - Domain regression: memory+project suites 180 pass / 0 fail; opencode+core typecheck clean; lint ratchet unchanged (0 new warnings).

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit R1-02 (P2 test-gap): the corrupt-manifest fail-closed guards had no test, so reverting them would let migrateHome delete an unread Memory Home. Now pinned: an invalid manifest and a manifest referencing a missing generation both fail readSnapshot, and migrateHome fails closed on the merge path with the source Home preserved. Both guards proven load-bearing by mutation (fail-open revert turns the test Red). R1-20 (P3 test-gap): decodeTopic item_count/items.length consistency was only covered by a since-deleted test. Re-pinned at both the decoder and the writeSnapshot generation gate (mutation-proven). R1-21 (P3 test-gap): a crash mid-writeSnapshot leaves an orphaned staging generation whose manifest was never published; pinned that it never shadows the committed generation and the store still commits cleanly (mutation-proven). Test-only change; no production code touched. - memory+project suites 183 pass / 0 fail; opencode+core typecheck clean; lint ratchet unchanged (0 new warnings).

pin cross-process commit conflict (MEM-PR01 M-F) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit R2-02: the branch collapses MEMORY config onto one project-primary file, written by three paths under mutually disjoint locks — /memory on|off (in-process KeyedMutex), admission promotion (memory-admission flock), and readConfig's normalization rewrite (no lock). atomicWrite prevents torn bytes but not whole-document last-writer-wins across worktrees/processes. All config file writes now serialize on a per-file cross-process flock (memory-config:): writeProject, writeGlobal, and the normalization rewrite. Pinned by a blocking-observation test; mutation-proven (dropping the lock lets a concurrent writer complete while the lock is held). Residual, documented rather than fixed (Occam): decision-level read-modify-write across processes is not CAS-protected — only the write primitives are serialized. A full cross-process RMW protocol would be over-engineering for the exposure. R2-03: the cross-process commit protocol's explicit-conflict guarantee (ADR-0002) was only exercised within one process. A new spawned-worker test commits with a stale expectedRevision from a second OS process and observes CommitConflictError deterministically (the pre-existing updateTopics race test only overlaps probabilistically). - memory+project suites 185 pass / 0 fail; opencode+core typecheck clean; lint ratchet unchanged (0 new warnings).

Rewritten to the actual authority structure (Store/Config/Admission/migrateHome/worktree guard + project identity migration): rejected-design glossary and invariants removed (Identity Alias, Canonical Project ID, tombstone retirement, opaque Revision, destruction guard); source Home described as migrate-then-remove with retention deferred; Project Configuration described as the unversioned .opencode/memory.jsonc; the read-leniency split stated (runtime read projects empty, strict reads and migration fail closed); ADR-0001's policy clause restored as live; ADR-0004 marked Rejected; the M-A…M-F behaviors reflected (global inertness, content-only conflicts, non-destructive list, fail-closed reset/remove, per-file config lock). R1-25: redo-plan internal consistency — header status no longer says PLANNING; the §10 resume protocol is marked superseded (no pending autonomous fix, only user decisions remain). R1-09 (spec-gap → decision): the git-exclusion narrowing to the two config candidates is intentional and now documented: preserved fail-closed legacy topic files stay visible in git status and committable; surfacing repair- pending files beats silently excluding user data. R1-14 (spec-gap → requirement): the openspec workspace is untracked, so this plan now carries the identity-upgrade requirement ("Identity upgrade preserves Project Memory and Project-owned references") with its scenarios, pinned by the M-A/M-B/M-C/M-E tests.

With Home keyed by project ID, an active Memory under `global` would (a) share one Home across all commit-less repositories on the machine (cross-repo topic leakage) and (b) be permanently orphaned at the first commit — identity moves global→root/remote but `migrateProjectId` never migrates away from global (explicit guard; `previous` can never be global).

One guard at the single activation seam (`Memory.configuration`, which active/prepare/search/checkpoint/setEnabled all funnel through); no new authority, no new machinery.

Previously it fell back to the default XDG-state lock dir, a DIFFERENT directory, so the writer fence and the migration fence never actually serialized. - flock-leak P2 (fence released before row deletion): ProjectIdentityMigration .migrate now holds memory-identity: for the WHOLE retirement — the Memory Home migration AND the caller's reference/row retirement — via a retireReferences callback. The fence is no longer released between the Home move and the old-row deletion, so an in-flight writer under oldID cannot slip into the gap. Callers pass their row retirement as the callback and no longer touch the fence themselves (single authority for the fence). Mutation check: removing retireReferences() from inside the fence turns the MEM-PR01-R1-11 permission-collision test Red (FK repoint no longer happens), confirming the seam wiring is load-bearing.

A retirement could complete while admission waited on the fence, and admission would then import legacy topics into the re-created retired Home AND delete the legacy source files (permanent orphaning — the identity cache already points at the successor, so no migration would ever run for the pair again). - F2 (P2): the phase-1 Home rename raced a concurrent newID writer creating the target between existsSafe and rename (ENOTEMPTY), dying fromDirectory. Self-healing (next boot retries into the merge path), no data loss. The identity-race TOCTOU class has now been found in three consecutive review rounds, and the memory-identity protocol (key + lock dir + in-fence liveness recheck) was hand-duplicated at four sites across three modules — exactly why admission could diverge from the writer discipline. Per the redesign rule this is a seam redesign, not a patch: - New MemoryIdentityFence (memory/identity-fence.ts) is the single authority for the protocol: key() builds the lock key, withLiveIdentity() holds the fence on home.locks AND re-checks the identity row inside the fence (None = retired, callers fail closed). A future path cannot forget the recheck. - Writers (prepare/search/checkpoint) and admission route through it; the retirement seam (ProjectIdentityMigration) stays the only raw fence holder (it deletes the row inside the fence) and builds its key from key(). - admission.ensure now fails with a tagged IdentityRetired error when the row is gone; configuration() stays inert, the worktree guard proceeds (the migration is moot after a completed retirement). - F2: rename failure with a target that appeared falls through to the snapshot-merge path; genuine FS failures still rethrow. Verification: Red test MEM-PR01-R7-F1 (ensure after row retirement must not import nor delete the legacy files) confirmed Red before, Green after; mutation removing the in-fence recheck turns it Red again. memory+project 189 pass / 0 fail; typecheck clean; lint flat at 4852. F2's mutation is registered as a test-gap: the race window is between two file ops with no observable state between them, so no deterministic public-seam test exists (the fallback routes into the already-tested merge path).

charset=UTF-8 Content-Transfer-Encoding: 8bit Round 9 product-invariant review found P2-A (introduced by M-J): the reconcileLegacyMemory guard returned undefined on IdentityRetired, so a worktree remove could proceed past the fence and `git worktree remove --force` would destroy legacy .opencode/memory content that was never admitted into any Home. The window sits between removeLocked's own row-liveness check and the admission fence recheck — widened by the WorktreeRemove hook (user scripts) that runs between the two. Fix: on IdentityRetired the guard now returns a blocker message (fail closed), matching the reset path's existing stance. A retry under the successor identity imports the legacy content first and then removes safely. Red-first + mutation evidence: - New test MEM-PR01-R9-P2A (worktree-remove.test.ts): holds the memory-admission flock so the remove blocks inside ensure after its own row check passed, retires the identity row, then releases — asserting the removal fails and the never-admitted legacy file survives. Red before the fix, Green after; reverting the blocker to undefined turns it Red again. Also fixes a standards-P2: reindents the retirement transaction body in project.ts (pure whitespace, no behavior change). Registered, not fixed here (out of PR scope): EffectFlock stale-break can silently lose a cross-process update (P2-B, pre-existing core infra, recorded as a residual for the final audit).
