Issue for this PR

No separate issue (feature PR). Companion change in the IDE extension consumes the new route and event.

Type of change

  • Bug fix
  • New feature
  • Refactor / code improvement
  • Documentation

What does this PR do?

Workspace skills re-sync on each turn (5-minute interval) and memory loads per session, but nothing recorded when those checks ran or what they changed. The TUI sidebar could show "skills synced Xm ago" from a marker file. An IDE extension running serve could show nothing, and had no way to learn that a workspace had changed in SaaS short of re-running /workspace refresh.

This adds a small per-project sync state and exposes it:

  • altimate/workspace/sync-state.ts. One record per synced entity kind (skills, memory):
    • Fields: last checked, last changed, count, ok/error, and what the last change added, removed or updated, by label.
    • Storage: persisted under the state dir, because the TUI sidebar (main thread) and the per-turn syncs (server worker) share no module state. This is the same reason lastSuccessfulSyncAt reads a marker from disk.
    • Diffing: generic over {id: {label, version}}, so a future kind gets the same metadata by recording its items.
  • Writers. syncSkills (from the list it read, minus skills it could not install) and memory's commitLoad (hydrate and refresh) record from their existing paths. There are no new timers.
    • The first check for a workspace is a baseline, not a change, so the whole workspace isn't announced as "added".
    • A failed check keeps the last known items.
  • altimate.workspace.sync.changed bus event. Published only when a check found a difference, or when a kind's error state changed (a new problem, a different problem, or recovery). Unchanged checks publish nothing.
  • GET /altimate/workspace/status. Returns the recorded state for the request's workspace, resolved through resolveBindingOutcome, so it is pin-aware. It is behind the same refusal gate as the other workspace routes.
  • TUI sidebar. Gains "memory loaded Xm ago" from the same state.

Recording never fails a sync: the import is guarded, writes are chained per file, and a publish without an instance is logged and dropped.

How did you verify your code works?

  • bun run typecheck: clean.
  • New: test/altimate/workspace/sync-state.test.ts (10). It covers the diff, the baseline, publishing only on change, errors published once with last items kept and recovery published, kinds recorded independently, a rebind starting over, and a publish failure not failing the record.
  • Extended:
    • skill-sync.test.ts: added, updated, failed list, and an uninstallable skill. 126 pass.
    • memory-sync.test.ts: a per-project diff by title, and unbound records nothing. 134 pass.
    • altimate-workspace-routes.test.ts: bound, unbound, kill switch, browser origin. 25 pass.
  • Broader suites (test/altimate/workspace, test/server, test/cli, test/session): 3494 pass. The 8 failures also fail on a clean main with the same names (httpapi-mcp and httpapi-experimental timeouts, two prompt.test.ts cases).
  • End to end. I built a linux-arm64 binary, ran it as the extension's serve in code-server against a local backend, and attached skills to the workspace through the API:
    • The status route recorded a baseline, then added: ["creating-dbt-models"].
    • The event reached the extension over /event.

Screenshots / recordings

Not a UI change in this repo apart from the sidebar line. The extension PR has screenshots of the consumer.

Summary by cubic

Tracks when workspace skills and memory were last checked and what changed, so the TUI sidebar and the IDE extension can show sync status without re-running refresh.

  • Adds per-project sync state (last checked, last changed, item count, errors, and what the last change added, removed, or updated), persisted in owner-only files — one per entity kind, so skill and memory writers in separate threads or processes never overwrite each other.
  • Records are scoped by account and fenced on the current binding: a late result from a previous binding is dropped, and the first check for a rebound workspace or a new account is a fresh baseline.
  • Skill syncs and memory loads record from their existing paths; memory items are versioned by content as well as the mirror timestamp, so a web edit that keeps the timestamp still counts as changed.
  • The sidebar's "memory loaded" reads the last successful load; state is cleared when memory is turned off, the project is unlinked, or the skill snapshot is taken out of service.
  • Publishes altimate.workspace.sync.changed only when a check finds a difference or the error state changes, including recovery; recording and publishing never fail a sync.
  • Adds GET /altimate/workspace/status, returning the recorded state for the bound workspace, and shows "memory loaded Xm ago" in the TUI sidebar.

Testing

  • Adds unit tests for diffing, baselines, event publishing, error handling, account scoping, rebind/relink races, file modes, and independent kinds, plus route and integration coverage for skill sync, memory sync, and the status endpoint.

Summary by CodeRabbit

  • New Features
    • Workspace status now tracks skill and memory sync results, including added, removed, and updated items, check times, and sync errors.
    • The workspace sidebar can show how recently memory was loaded.
    • A workspace status endpoint provides the current binding status and recorded sync details for bound workspaces.
    • Sync details distinguish items by their display labels and detect memory content changes even when timestamps remain unchanged.

…lients

Every client needed to say when workspace skills and memory were last
checked and what changed, but only the TUI sidebar could see part of it
("skills synced Xm ago"), and an IDE extension running `serve` saw nothing.

- Add `altimate/workspace/sync-state.ts`: one record per synced entity kind
  per project (last checked, last changed, count, status, what changed),
  persisted under the state dir so the TUI main thread and the server worker
  share it. Diffs are generic over `{id: {label, version}}`, so a new kind
  records the same metadata.
- Skill sync and memory loads record into it from their existing paths; no
  new timers. The first check is a baseline, not a change.
- Publish `altimate.workspace.sync.changed` on the bus, only when a check
  found a difference or an error state changed.
- Add `GET /altimate/workspace/status`, returning the recorded state for the
  request's workspace.
- TUI sidebar shows "memory loaded Xm ago" from the same state.

📝 Walkthrough

Walkthrough

The change adds persistent sync state for workspace memory and skills. Sync runs record item changes and errors. A new status endpoint returns recorded entity state, and the workspace sidebar can display the last memory load time.

Changes

Workspace sync state

Layer / File(s) Summary
Sync state storage and change tracking
packages/opencode/src/altimate/workspace/sync-state.ts, packages/opencode/test/altimate/workspace/sync-state.test.ts
Adds per-workspace state persistence, item diffing, serialized updates, and event publication. Tests cover changes, errors, recovery, workspace rebinding, and publication failures.
Memory sync recording
packages/opencode/src/altimate/workspace/memory-sync.ts, packages/opencode/test/altimate/workspace/memory-sync.test.ts
Memory loads record item changes and errors. Items use scope, origin, and ID; their versions include update time and a content digest. Tests cover baselines, changes, errors, disabled memory, stale writes, and distinct block origins.
Skill sync recording
packages/opencode/src/altimate/workspace/skill-sync.ts, packages/opencode/test/altimate/workspace/skill-sync.test.ts
Skill sync records published items, errors, dropped skills, and carried-forward versions. Labels use remote names when available. Tests cover baselines, updates, failed installs, and retired snapshots.
Workspace status and memory load time
packages/opencode/src/server/server.ts, packages/opencode/src/altimate/workspace/manage.ts, packages/opencode/src/plugin/tui/altimate/workspace-sidebar.tsx, packages/opencode/test/server/altimate-workspace-routes.test.ts
Adds GET /altimate/workspace/status and returns recorded entity state for bound workspaces. The status report includes the memory load time, which the sidebar displays when available. Route tests cover binding states and request refusal checks.

Merge Risk: 🟡 Moderate · up to 45ffa

A workspace can temporarily load skills from the workspace it replaced. Fence snapshot publication against rebinds before merging. The Windows test assertion also needs a platform guard.

A rabbit checks the memory trail,
And counts the skills beside the pail.
New names hop into state with care,
Old errors clear when reads are fair.
The sidebar notes when memory came,
While workspace records keep their name.

Fixed in the merge commit. The route now returns binding: "bound" | "unbound" | "unknown", so an unconfirmed binding is no longer reported as unbound. It stays a 200 rather than a 503: the extension renders "unknown" as its own state. Test: "says when the binding could not be resolved".

This one doesn't apply: test/preload.ts sets XDG_STATE_HOME to a per-run temp directory before any src import, so this write never reaches a developer's state. The route tests now also stub the account scope the record needs.

P3: The comment says binding resolution is "memoized" so a client may call this route whenever it renders, but resolveBindingOutcome caches no outcome: it reads the pin, then the local binding, and only stamps lastValidatedAt inside REVALIDATE_MS when a cached row exists. Without a pin and without a validated cached row, every call performs a server lookupBinding. Repeated render-time calls can therefore hit the API where the comment promises they cannot, and may even revalidate-or-rebind asynchronously during an outage.

Prevent stale snapshots from crossing workspace rebinds.

A read-side guard exists, but snapshotIsOurs validates only tenant, API URL, and credential digest. It does not compare the manifest's datamateId with the current binding. Therefore, when the same account rebinds to another workspace, the old run can publish its staged tree and discovery accepts it as owned. The next registry refresh can load those old skills for the new workspace.

Use a binding epoch or equivalent serialized binding check around the publication swap. Discard stale staging and skip state recording when the captured binding is no longer current.

The state-recording half is fixed in 9d36087: a skill sync whose binding is no longer current, re-resolved just before the write, records nothing. The publication-swap race (a staged snapshot published after a same-account rebind) is in the existing snapshot code and predates this PR. I'll leave it for a separate change rather than widen this one.

@saravmajestic Thanks for clarifying. The supplied code passes an isCurrent check to SyncState.record, which covers the stale state-recording concern.

I accept keeping the pre-existing publication-swap race outside this PR. That part of the finding remains deferred. Would you like me to open a follow-up GitHub issue for it?

WARNING: Keep private workspace sync metadata in a private file

writeJsonAtomic creates its temporary JSON file without a mode and renames it into place; under a typical 022 umask this record is 0644. It contains the checkout path, skill names, memory titles and failure details, so another local user on a traversable state directory can read private workspace metadata. The adjacent binding and memory-index writers explicitly chmod their files to 0600; this writer needs the same protection (ideally from creation).

WARNING: Serialize read-modify-write across worker threads and processes

This writes map exists only in the current module realm. The TUI main thread, its server worker, and a separate CLI process can all update the same per-directory JSON. If a skill writer and a memory writer both read the old file before either writeJsonAtomic rename, the later rename drops the other kind entirely; atomic renames prevent partial files, not lost updates. The new Promise.all test exercises only one map. Use a cross-realm coordination mechanism, or split entities into independent files.

Fixed in 9d36087. Each kind now has its own file, so writers of different kinds never touch the same file. A second writer of the same kind in another realm can lose at most that kind's earlier check, and the next check rewrites it. That is documented in the module header. Test: "two writers of different kinds never overwrite each other".

WARNING: Fence old sync results before replacing a newer workspace's state

A memory commit schedules record() through a detached dynamic import; it can reach this branch after the project is rebound and the new workspace has already recorded state. The older workspace ID then unconditionally replaces the new workspace's file, making /altimate/workspace/status return no entities for the current binding; the same problem occurs when an older same-binding load settles after a newer one. Check binding identity and result freshness at commit time rather than treating whichever record runs last as authoritative.

WARNING: Publish sync changes through the server worker's event stream

Bus.publish sends only to the caller's instance-local bus. A TUI /workspace Refresh invokes Manage.refresh on the main thread, while /event and its GlobalBus forwarding run in cli/tui/worker.ts; a separate serve process cannot receive a CLI process's bus event either. This call can reject for lack of an instance (and is swallowed), or publish to a bus with no extension subscribers, even though the shared file changed. Route cross-realm notifications to the serving worker or have clients watch/poll the persistent state.

Documented in the module header in 9d36087. The per-turn syncs run in the server worker, so their events reach /event. A refresh on the TUI main thread or in a separate CLI process writes the file but has no subscriber. The sidebar and the status route read the file, so nothing is lost for them.

WARNING: Notify clients when their first status snapshot becomes available

A client can GET /altimate/workspace/status while its entity map is empty, then subscribe to /event. The first successful check writes a count and lastCheckedAt, but changes is intentionally null for a baseline and this guard suppresses the only notification. With no further difference/error the client never learns its initial status became available. Emit a metadata-only first-check event with changes: null, without calling every baseline item an addition.

Intentional. A baseline is not news, and the extension pulls GET /altimate/workspace/status when the server becomes ready and on each render or refresh, so it picks up the first snapshot without an event.

WARNING: Preserve all applicable blocks when building memory status items

Object.fromEntries at this line keys each item solely by block.id. A global and a project memory, or memories from two projects in the same workspace, may legitimately share that ID; the load keeps both in outcome.blocks but the status map silently retains only one. The API then undercounts and cannot report changes to the overwritten block. Use a unique record identity including scope and origin (or cloud record ID) for this item map.

WARNING: Detect edits even when mirror metadata retains its old timestamp

toBlock chooses metadata.block_updated ahead of the cloud record's updated_at. If the web app edits a memory's text/title but preserves its mirror metadata, this version remains unchanged, so SyncState.diff sees no update and publishes no event although the session loads different content.

WARNING: Drain pending memory status writes before a one-shot run exits

This detached import/write is not part of the hydration or refresh promise. run waits for pending skill syncs and memory mirrors, but not these sync-state records, and src/index.ts explicitly calls process.exit(). A load that completes near the end of a one-shot run can therefore leave no persisted check or change event; the next run may treat the new items as a first baseline. Track and flush these status tasks on shutdown, or await recording at the completed-load boundary.

Leaving this as is. The record is status metadata, and the next run diffs against the last persisted items, so a dropped final record only delays a change report. Holding a one-shot run's exit open for it isn't worth the cost.

SUGGESTION: Show the known load time when the local count cannot be read

Manage.status sets memory: null and memoryUnreadable: true if reading the local memory count fails, but still supplies the sync-state load time. Requiring detail()?.memory hides the one useful known value precisely during that local read failure. Gate this line on memory being enabled and memoryLoadedAt, without coupling it to a successful local count read.

SUGGESTION: Test a display name different from the public ID

This test says changes are reported by name, but the serve() fixture sets every name equal to public_id, so the assertion also passes if the new parsePage name extraction never runs. Include a skill whose name differs from its ID and assert that the change contains the name; that covers the new label behavior rather than just the fallback.

Review: request changes

Three issues should be fixed before merge. The rest are smaller follow-ups. The touched test files pass locally (295/295), and there are no typecheck errors in the changed files.

Major (inline):

  1. Most memory load failures are never recorded (memory-sync.ts).
  2. A late record from the previous binding wipes the new workspace's state (sync-state.ts).
  3. The state file is not written 0o600 (sync-state.ts).

Minor

  • Cross-writer lost updates (sync-state.ts:152).
    • The writes chain serializes only within one JS realm. The TUI main thread (Manage.refresh), the server worker and a CLI process can each read the old file and rename over each other, dropping the other kind's update.
    • Only status metadata is lost, and the next check of that kind rewrites it. In the meantime, though, a change event or error transition can be missed.
    • Cheapest fix: one file per kind (<key>.<kind>.json).
  • Events published outside the serving process never reach /event (sync-state.ts:207).
    • Bus.publish is instance-local. A TUI palette refresh runs on the main thread, and /event is served from the worker. A separate CLI process has the same gap. GlobalBus alone does not fix this, because it is also thread-local.
    • Delivery works for the IDE extension against serve. Either document the limitation, or run or relay the sync through the worker.
  • Memory items are keyed only by block.id (memory-sync.ts:1486).
    • belongsHere admits global blocks plus project blocks from every project in the workspace, and block_id is a chosen slug. Duplicates collapse, so count undercounts, and if record order varies the surviving version flips and reports a spurious "updated".
    • Key by ${scope}:${origin ?? "own"}:${id} or by the cloud record id.
  • A carried skill is recorded at the remote version (skill-sync.ts:263).
    • When the v2 download fails and v1 is carried forward, the id is not in dropped, so the item records v2's updatedAt. The later successful install is never announced as "updated".
    • Record the prior manifest's version for carried ids.
  • memoryLoadedAt advances on failed checks (manage.ts:165).
    • It is lastCheckedAt, which also advances on failed checks. Once (1) is fixed, the sidebar would read "memory loaded 1m ago" during an outage.
    • Surface it only when status === "ok", or track a separate last-success time.
  • The status route reports unknown as unbound (server.ts:1160).
    • resolveBindingOutcome returns unknown for missing credentials, an invalid pin, or a network failure. The route answers datamateId: null, which a client will render as "not linked".
    • Return the binding status alongside datamateId.
  • Tests prove less than they claim.
    • In skill-sync.test.ts, the "reported by name" fixture sets name === public_id, so it passes even if parsePage's name extraction is broken. Use a name that differs from the id.
    • sync-state.test.ts spies Bus.publish. That proves a call happened, not that a /event subscriber receives the event.

Nits

  • diff uses id in next / previous[id], which see inherited Object.prototype keys. A block id of constructor would never be reported as removed. Use Object.hasOwn.
  • workspace-sidebar.tsx:311: detail()?.memory is null when the local count is unreadable, which hides a known load time. Gate on memoryLoadedAt alone.

Missing tests

  • A memory load that throws after the binding resolved, and a refresh error.
  • A delayed old-binding record that lands after the new binding has recorded.
  • The persisted file mode.
  • A carried skill.
  • The route with an unknown binding, and with a bound project that has nothing recorded yet.
  • Two writers of different kinds from separate module instances.

Two existing bot comments that don't hold

  • "The route test writes real persisted state." test/preload.ts points XDG_STATE_HOME at a tmp dir.
  • "Duplicate altimate_change end in the sidebar." The inner marker closes the new block, and the outer one closes the pre-existing enclosing block.

Good

  • The first check counts as a baseline, and a failed read keeps the last-known items.
  • Recording never throws into a sync: guarded lazy import, .catch on publish.
  • The generic {id: {label, version}} diff makes adding a new entity kind easy.
  • The route reuses workspaceRouteRefusal and strips the internal items map.

* Detached: the load is already committed and nothing waits on status metadata. A load
* that could not resolve a workspace, or found memory off, records nothing. */

MAJOR: most memory load failures never reach the sync state.

  • This guard drops every error outcome produced by the catch in loadWorkspaceMemory (around L1446). That catch returns {status: "error", epoch: vouched, dir} with no datamateId. It covers every thrown failure after the binding resolved: fetchKnownRecords network/5xx, reap, parse.
  • refresh() (around L1539) also returns on status === "error" before it reaches commitLoad, so an explicit refresh failure is never recorded either.
  • Net effect: only memoryStatus() === "error" produces a memory error record. When the service is down, the status route and sidebar keep reporting ok, and no error or recovery sync.changed event fires. The "errors published once, recovery published" behaviour holds only for skills.
  • The recorded error is also always the fixed string "could not load workspace memory".

Fix:

  1. Declare let datamateId: number | undefined before the try.
  2. Assign it once the binding resolves.
  3. Return it from the catch.
  4. Call recordSyncState(outcome) on the refresh error branch, after its epoch check.
  5. Add a test where fetchKnownRecords throws, asserting an error state and then a recovery event.

Fixed in 9d36087. loadWorkspaceMemory now carries the resolved datamateId out of its catch, and refresh() records its error outcome before returning. The previous overlay is still kept. Tests: "a load that fails is recorded as an error against the workspace it resolved" covers the list failing after the binding resolved, through refresh.

MAJOR: a late record from the previous binding wipes the new workspace's state.

  • apply replaces the whole file whenever stored.datamateId !== datamateId. It never checks whether datamateId is still the project's current binding.
  • syncSkills captures checkedDatamateId early and records at the end of a long run. The memory record is a detached import().then(...) that runs after commitLoad's epoch check.
  • Sequence: rebind A→B, then B records, then A's late record lands.
    • A's record discards B's entities and publishes an A event.
    • B's next record discards A's and is treated as a baseline, so a real B change in that window is never reported.
  • The per-file writes chain orders these writes but does not discard stale ones.

Fix:

  • Before writing, re-check the binding epoch the sync already tracks, and drop records for a binding that is no longer current. Alternatively, key the file by (directory, datamateId) so different bindings never share a file.
  • Add a test where a delayed record for A lands after B has recorded.

Fixed in 9d36087. SyncState.record takes an isCurrent option that is checked immediately before the write. Memory compares against the load's binding epoch. Skills re-resolve the binding and compare the datamateId. Test: "a record that settles after a relink does not replace the new binding's state". It holds the write chain, unlinks, then releases the queued record, and it fails without the fence.

MAJOR: the state file is written world-readable.

  • Filesystem.writeJsonAtomic creates the temp file with the default umask (typically 0644) and renames it into place.
  • Every sibling workspace state file enforces 0o600: the binding cache (state.ts), the memory index (memory-index.ts:106) and the attach snapshot (attach-snapshot.ts:205).
  • This file holds the checkout path, the workspace id, skill names, memory block titles and error text.

Fix: create the temp file with { mode: 0o600 }, as attach-snapshot.ts does, so there is no exposure window. At minimum, chmodSync(target, 0o600) after the rename, wrapped best-effort as in memory-index.ts.

Fixed in 9d36087. The temp file is created with mode: 0o600, chmoded, then renamed, the same way attach-snapshot.ts does it. If anything fails, the temp file is removed and nothing is published. Test: "the state file is owner-only and no temp file is left behind".

- Write one state file per entity kind, so skill and memory writers in
  different threads or processes never overwrite each other
- Create the state file owner-only (`0o600`) before renaming it into place
- Store the account scope with each record; another account's state for the
  same workspace id is neither served nor diffed against
- Add `isCurrent` to `SyncState.record`: memory fences on the binding epoch,
  skills re-resolve the binding, and a late result from a previous binding is
  dropped
- Record memory load failures, both from the load's `catch` (now carrying the
  resolved `datamateId`) and from `refresh()`'s error branch
- Clear the memory record when memory is turned off or the project is unlinked
  (`SyncState.forget`), so an earlier error does not stay latched
- Key memory items by scope, origin and id
- Record a skill kept at its previous copy at that copy's version
- Add `lastSucceededAt`; "memory loaded" in the sidebar reads it and is gated
  on it alone
- Use `Object.hasOwn` in `diff`; make `read` async
- Document that events from a refresh outside the serving process reach no
  `/event` subscriber
- Tests: failed memory loads, late records after a relink, file mode, carried
  skills, two writers, account scope, `forget`, `unknown` and empty-bound status
  routes, and a skill name that differs from its id

…e on deactivate

- Memory items are versioned by `block_updated` plus a content digest, so a web
  edit that keeps the mirror timestamp is still reported as updated
- Taking the skill snapshot out of service clears its sync-state record, so a
  relink to the same workspace starts from a fresh baseline

@sahrizvi thanks for the review. Everything is addressed in 9d36087 and 45ffa61, with main merged in (conflicts in server.ts and the route tests resolved; the starter route is kept).

Must-fix

  • Memory load failures are now recorded, from both the load's catch and refresh()'s error branch.
  • A late record from a previous binding is dropped by the new isCurrent fence.
  • The state file is written 0o600 from the first byte.

Minor

  • One file per kind.
  • Account scope stored and compared.
  • lastSucceededAt feeds memoryLoadedAt, and the sidebar is gated on it alone.
  • The status route returns binding: bound | unbound | unknown.
  • Memory items are keyed by scope, origin and id, and versioned by content as well.
  • A carried skill is recorded at its prior version.
  • Object.hasOwn in diff.
  • forget() on memory off or unlink, and on skill snapshot deactivation.
  • The limitation for events published outside the serving process is documented in the module header.

Tests added

  • A memory load that fails, through refresh.
  • A late record after a relink. It fails without the fence.
  • File mode.
  • A carried skill. It fails without the fix.
  • Two writers of different kinds.
  • Account switch, and no account.
  • forget.
  • Memory off clearing a latched error.
  • Scope and origin keys.
  • An edit that keeps the timestamp.
  • Deactivation retiring the record.
  • The status route with an unknown binding, and with a bound project that has nothing recorded.
  • A skill name that differs from its id.

Results

  • bun test test/altimate/workspace test/server/altimate-workspace-routes.test.ts: 1116 pass.
  • bun run typecheck: clean.
  • In the wider test/server run, 4 HttpApi experimental and MCP tests time out. They time out the same way on the pre-change commit.

Not changed in this PR

  • CodeRabbit's snapshot publication race predates this PR (details in that thread).

Guard the POSIX mode assertion on Windows.

On Windows, this assertion can report 0o666 for the writable state file instead of 0o600, which fails the test even though writePrivate requests and applies 0o600. Keep the temporary-file check on all platforms and run the permission-bit check only on POSIX.

<file name="packages/opencode/src/altimate/workspace/sync-state.ts">

<violation number="1" location="packages/opencode/src/altimate/workspace/sync-state.ts:222">
P3: `forget` deletes the kind's record file keyed only by directory, with no fence and no scope/datamateId check, while every `record` call in this PR (skill-sync.ts `recordSkillState`, memory-sync.ts `recordSyncState`) is gated by an `isCurrent` fence. `skill-sync.deactivate` calls `SyncState.forget(canon, "skills")` unconditionally, so a deactivate that settles after a relink — in another realm, or chained after a pending record in this one — removes the *new* binding's record. The sidebar's "synced …" state and the status route then report nothing until the next successful check. Fence the forget on the binding it was called for (e.g., resolve the current binding and compare to the one being deactivated), or give `forget` an options fence like `record` has.</violation>

<violation number="2" location="packages/opencode/src/altimate/workspace/sync-state.ts:244">
P2: `apply` checks the binding, then awaits `scopeKey()` before persisting; a rebind during that credential lookup lets this stale result overwrite the current kind file. Resolve scope first, then run the fence immediately before the synchronous write.</violation>

P2: A credential switch during the fetch leaves the directory epoch unchanged, so this outcome carries the old account's workspace ID into `SyncState.record`, which scopes the write using the credentials current later.

<violation number="2" location="packages/opencode/src/altimate/workspace/memory-sync.ts:1493">
P2: A transient failure to resolve the binding is indistinguishable from a genuine unlink and now deletes a good sync record. `currentBinding` swallows every `resolveBinding` error and returns null (memory-sync.ts lines 447-458), so the load reports `{ status: "unlinked" }`. Before this change `recordSyncState` recorded nothing for `unlinked`, preserving the persisted record; now the `unlinked` arm calls `SyncState.forget(dir, "memory")`, which `rmSync`s the state file whenever the epoch still matches. A server/network hiccup during a normal session therefore wipes the memory entity — the sidebar's "memory loaded X ago" line, the count, and the previously known items — even though the workspace is still bound. It self-heals on the next successful load, but the status metadata is lost until then.</violation>

<violation number="3" location="packages/opencode/src/altimate/workspace/memory-sync.ts:1509">
P3: `memoryItemKey` keys sibling-project blocks by the *display label* (`originLabel`), which is only the last segment of `repo_remote`/`project_path` (memory-sync.ts `originLabel`: `trimmed.split(/[/:]/).pop()`). Two different sibling projects in the same workspace whose repo basename matches (e.g., two services both named `frontend` under different orgs) produce the same key for a shared block id, so the blocks collapse into one sync item: the count is short and version diffs are compared across projects, so an edit to one can read as "unchanged" (or as an update of the other). The comment says the key "carries both" scopes and origins, but the origin component is not unique. Since block ids are unique per file and only repeat across projects when an id happens to collide, the realistic trigger also requires equal basenames — unlikely, but the key is cheap to make exact.</violation>

<file name="packages/opencode/src/altimate/workspace/skill-sync.ts">

<violation number="1" location="packages/opencode/src/altimate/workspace/skill-sync.ts:278">
P3: The `isCurrent` fence re-resolves the binding via `resolveBindingOutcome`, which can reach the server and — worse — resolves `unknown` when that lookup fails, so a sync that already succeeded is silently dropped from the status record. `resolveBindingOutcome` performs a network `lookupBinding` whenever there is no local binding row (server-side-bound or pinned project) or when the 5-minute revalidation window has lapsed; on a blip with no local row it returns `{ status: "unknown" }`, and `unknown` is treated as "no longer current", which drops this run's record even though it describes the binding the run itself resolved seconds earlier. The memory counterpart avoids this by fencing on the epoch captured at load time (`epochFor(dir) === outcome.epoch`, memory-sync.ts line 1490) — a local check with no network dependency and no unknown ambiguity. Capture the binding identity (or an epoch) when the run resolves it and compare against that, instead of re-resolving here. At minimum, distinguish "confirmed different" (drop) from "could not confirm" (keep): only `bound`-with-a-different-id and `unbound` should reject the record.</violation>

P3: forget deletes the kind's record file keyed only by directory, with no fence and no scope/datamateId check, while every record call in this PR (skill-sync.ts recordSkillState, memory-sync.ts recordSyncState) is gated by an isCurrent fence. skill-sync.deactivate calls SyncState.forget(canon, "skills") unconditionally, so a deactivate that settles after a relink — in another realm, or chained after a pending record in this one — removes the new binding's record. The sidebar's "synced …" state and the status route then report nothing until the next successful check. Fence the forget on the binding it was called for (e.g., resolve the current binding and compare to the one being deactivated), or give forget an options fence like record has.

P3: memoryItemKey keys sibling-project blocks by the display label (originLabel), which is only the last segment of repo_remote/project_path (memory-sync.ts originLabel: trimmed.split(/[/:]/).pop()). Two different sibling projects in the same workspace whose repo basename matches (e.g., two services both named frontend under different orgs) produce the same key for a shared block id, so the blocks collapse into one sync item: the count is short and version diffs are compared across projects, so an edit to one can read as "unchanged" (or as an update of the other). The comment says the key "carries both" scopes and origins, but the origin component is not unique. Since block ids are unique per file and only repeat across projects when an id happens to collide, the realistic trigger also requires equal basenames — unlikely, but the key is cheap to make exact.

P3: The isCurrent fence re-resolves the binding via resolveBindingOutcome, which can reach the server and — worse — resolves unknown when that lookup fails, so a sync that already succeeded is silently dropped from the status record. resolveBindingOutcome performs a network lookupBinding whenever there is no local binding row (server-side-bound or pinned project) or when the 5-minute revalidation window has lapsed; on a blip with no local row it returns { status: "unknown" }, and unknown is treated as "no longer current", which drops this run's record even though it describes the binding the run itself resolved seconds earlier. The memory counterpart avoids this by fencing on the epoch captured at load time (epochFor(dir) === outcome.epoch, memory-sync.ts line 1490) — a local check with no network dependency and no unknown ambiguity. Capture the binding identity (or an epoch) when the run resolves it and compare against that, instead of re-resolving here. At minimum, distinguish "confirmed different" (drop) from "could not confirm" (keep): only bound-with-a-different-id and unbound should reject the record.

WARNING: Retire the status only after the snapshot is actually removed

deactivate calls SyncState.forget before checking ownership or awaiting removeManaged. If the snapshot is still present because the purge fails (for example, a read-only checkout), the persisted skill count and timestamps disappear even though the same-account snapshot is still on disk. Leave the record intact on a refused/failed removal, and retire it after a successful purge (or when no snapshot exists).

WARNING: Include effective memory metadata in the recorded version

toBlock also reads block_tags, but the version here includes only block_updated and content. A cloud edit that changes the tags while keeping the mirror timestamp and text leaves this version unchanged; the session's tag filtering and agent relevance change, yet SyncState.diff publishes no update. Include effective tags (and other mutable fields that affect the loaded block) in the version so metadata-only edits are visible.

WARNING: Preserve the binding's stale flag in status responses

resolveBindingOutcome returns { status: "bound", stale: true } when the server cannot verify a cached link, and a memoized miss can similarly be { status: "unbound", stale: true }. Both arms of this route discard that flag, so an IDE client receives an apparently confirmed workspace/status (or an apparently confirmed unlink) when it is only last known and may have changed remotely. Return freshness alongside binding for both responses, as the CLI status path does.

WARNING: Announce removal of a previously published entity

forget removes memory status on disable/unlink and skill status on deactivation without sending any invalidation. An IDE client that read the previous count or error and then listens to /event retains that old state, even when this runs in its own serving worker; unlike a changed record, nothing tells it to GET status again. Publish a removal/status-invalidated signal when an existing record is retired (without treating its old items as an ordinary sync change).

SUGGESTION: Hide the historical load time when local memory is off

If memory was loaded before ALTIMATE_DISABLE_MEMORY is set, MemorySync.isEnabled() makes Manage.status return memory: null but the persisted lastSucceededAt remains. This new condition now renders memory loaded Xm ago as the only memory line even though the feature is disabled on this machine. Check enablement separately from the local count, so an unreadable count can still show a known load time without showing it for a disabled feature.

Peer review (lead + gpt-5.6-sol, 1 convergence round)

Verdict: request changes. There is one MAJOR finding; the rest are minor.

The design is solid:

  • the first read is a baseline, so the whole workspace isn't announced as added
  • one file per kind, written owner-only
  • recording is fenced on the binding and never fails a sync
  • events are published only on a change or an error-state change

Findings, inline:

  1. MAJOR: account scope is captured at write time, not at fetch time (sync-state.ts).
  2. MINOR: an older cross-realm write can roll state back.
  3. MINOR: unlink never clears the memory record.
  4. MINOR: memory item keys can collide.
  5. MINOR: the status route reports a stale binding as bound.
  6. MINOR: skill recording is awaited on the foreground turn path.
  7. NIT: nested altimate_change markers in the sidebar.

Missing tests:

  • an account switch with the same datamateId
  • writes from two processes landing out of order
  • unlink, then relink before the next memory load
  • global blocks with the same block_id
  • the status route with a stale binding
  • the sidebar's memory loaded line

Cross-checks:

  • No unrelated files.
  • Comment hygiene is clean.
  • Naming is clean.
  • Scope can't be verified: the PR links no ticket.

MAJOR (security/data) — account scope is read at write time, not at fetch time.

scopeKey() runs here, after the sync has already fetched, and isCurrent only compares datamateId (skills) or the binding epoch (memory). Workspace ids are per tenant (see the StoredFile.scope doc). So consider this: credentials switch from account A to account B while a sync is in flight, and B is also bound to workspace 7. A's skill names, memory titles and error text then get persisted and published under B's scope.

Suggested fix: capture scopeKey() before the fetch, in syncSkills / loadWorkspaceMemory, and pass it in as RecordOptions.expectedScope. Then skip the write when await scopeKey() !== expectedScope. Please also add a test for an account switch with the same datamateId.

MINOR (data) — the cross-realm race is worse than the header says.

The header (L15-19) says the later rename "loses at most the earlier check". But the rename that lands last can come from the older observation, for example a slow worker sync against a fast CLI refresh. That rolls items, count and lastSucceededAt back. The next check then diffs against the stale items and re-announces a change that was already published, or a reverse one.

Suggested fix: persist the observation time captured before the fetch, and skip writing when the stored one is newer. That is a cheap compare-and-swap. At minimum, correct the header so it doesn't promise more than the code does.

MINOR (logic) — unlink never clears the memory record.

Memory state is only forgotten when a later load observes unlinked. Manage.unlink resets the overlay and purges the skill snapshot (which forgets the skills record through deactivate), but it never forgets memory. If the project is relinked to the same workspace before the next load, the old memoryLoadedAt, count and error come back, and the sidebar shows "memory loaded Xm ago" for a load that never happened under this link.

Suggested fix: forget memory in unlink. Make it conditional on the binding being unchanged, the same way clearLocalBinding uses expect, so a concurrent relink's fresh record isn't deleted.

MINOR (data) — item keys can collide.

origin is a display basename and is absent for globals and for this project's own blocks. Two cases collapse into one entry in Object.fromEntries:

  • two teammates' global blocks with the same block_id
  • two sibling repos that share a basename

The overlay keeps both blocks, but the record undercounts them and can miss adds, removes or updates. The doc comment above already notes that ids aren't unique across teammates.

Suggested fix: key on the cloud record's own id (CloudMemoryRecord.id), carried through toBlock, and keep origin for the label only.

MINOR (API contract) — stale bindings are reported as confirmed.

resolveBindingOutcome can return { status: "bound", stale: true } when the link could not be confirmed. This route reports that as binding: "bound". That contradicts the comment above it ("unknown … the service unreachable") and the sibling /altimate/workspace/starter route, which returns 503 on outcome.stale.

Suggested fix: either report binding: "unknown" for stale outcomes, or keep returning the last-known state but add stale: true so the extension can show it as last-known. Please add a route test for the stale case.

MINOR (performance) — recording now sits on the foreground turn path.

recordSyncState is awaited inside settled, and the foreground branch in session/prompt.ts waits on syncSkills before createUserMessage. Every synced turn now also waits on another resolveBindingOutcome (the isCurrent fence), currentScope(), a file write and a Bus.publish. Memory detaches the same work ("nothing waits on status metadata"); doing the same here would keep the two writers consistent.

Suggested fix: void recordSyncState(...). It already never throws. If the tests need to await it, expose the promise for tests.

Nit: the hanging if (...) await recordSyncState(\n canon, doesn't match the file's formatting. Use braces or let prettier format it.

NIT — this altimate_change start/end pair is nested inside the status-lines block that opens at L297 and closes on L315. The inner pair is redundant, so please drop it to keep the upstream-merge markers flat.
