In `@internal/server/server.go`:
- Around line 293-294: Extend the end-session route tests for handleEndSession
to force EndSession to return store.ErrSessionBusy, then assert an HTTP 409
response and the expected JSON error body. Keep the existing success and
not-found coverage unchanged.
In `@internal/store/store.go`:
- Around line 3658-3660: Update the session conflict-update SQL to preserve
existing non-empty ended_at and summary values, only using incoming closure
fields when the stored values are missing; apply this consistently across both
conflict paths and add replay tests covering conflicting non-empty closure
values.
In `@internal/sync/sync.go`:
- Around line 459-460: Update the sync flow around ReadChunk and
filterNewDataWithSessionClosures to detect and recover manifest entries whose
chunks are missing before incremental cutoff filtering. Reconstruct the complete
content when possible and replace the stale manifest entry; otherwise remove it
and return an explicit recovery error. Extend
TestLocalSyncRecreatesManifestChunkMissingFromActiveTransport with an
observation and prompt to verify historical data is preserved.
In `@plugin/opencode/engram.ts`:
- Around line 347-415: Remove archive lifecycle policy from the adapter by
relocating closeArchivedSession, enqueueSessionEvent,
closePendingArchivedSession, and handleArchivedSession, along with their project
matching, outcome tracking, queueing, and status-check coordination, into the
core Go API or tool. Keep the adapter responsible only for parsing events,
invoking the core operation, and returning its result; preserve the existing
terminal, deferred, and closed behavior through the core interface.
- Around line 411-414: Update archive and cancellation handling in
handleArchivedSession and the corresponding OpenCode adapter copy so
cancellation increments the session generation before enqueueing cleanup.
Capture the archive generation and validate it after every await and immediately
before endSession, preventing closeArchivedSession from ending a cancelled
session. Add a deterministic test that keeps status or closure pending while an
unarchive or deletion event arrives.
- Line 272: Update the endSession retry flow around the fetch call to catch
rejected POST requests and retry them using the existing retry policy, not only
non-OK responses. Ensure exhausted failures still follow the current
cleanup/error path so closePendingArchivedSession does not leave the session
permanently pending; apply the same behavior in the corresponding setup plugin
implementation.

Recover missing manifest chunks before incremental filtering. A manifest chunk ID marks the chunk as known, but exportedSessionClosureStates skips that ID when ReadChunk returns ErrChunkNotFound. filterNewDataWithSessionClosures then exports only sessions with new or unexported closure state; it excludes older observations and prompts. The resulting content hash differs from the missing manifest ID, so lines 459-460 do not recreate the missing entry. The stale manifest entry remains unavailable to new importers, which cannot recover the historical data.
Scan manifest entries for missing chunks before applying the cutoff. If the complete content cannot be reconstructed, create a complete replacement snapshot and remove the stale entry, or return an explicit recovery error. Extend TestLocalSyncRecreatesManifestChunkMissingFromActiveTransport to include an observation and prompt.

Move archive lifecycle policy out of the adapter.
The plugin/** contract requires adapters to parse input, call the core Go API or tool, and return. This block applies project matching rules, selects closure outcomes, tracks session lifecycle state, queues event operations, and coordinates OpenCode status checks. Move this reusable archive lifecycle policy into the core Go API or tool. Keep the adapter limited to event parsing and API calls.

Learning: In the OpenCode and Pi TypeScript adapters, acquire host-runtime session identity and translate OpenCode parent-session IDs within the adapter because OpenCode provides `parentID` and `sessionID`, while Pi provides `sessionManager` identity. Fail closed until the existing session-registration request is acknowledged. Keep generic session existence, cardinality, and project validation in the Go core; moving host-specific binding into Go requires a new transport contract or persisted binding state.

Solid direction, and the core safeguards match the acceptance criteria: SELECT-then-guard in EndSession, ErrSessionBusy, and summary preservation are exactly what the issue asked for. I also checked the plugin diff against the in-flight #1218 work: no new Bun.* calls, which will matter below. A few things before this can land:
-
Rebase needed, and CI has never run on it. The branch is conflicting with main, so GitHub skipped the pull_request workflows entirely (only the label and issue-reference checks executed). The full suite (lint, unit, e2e, Windows) will run for the first time after the rebase, so it is worth doing that before deeper review.
-
Sequencing with #1227. #1227 rewrites plugin/opencode/engram.ts and the embedded mirror (Bun APIs to Node builtins behind a nodeRuntime seam) and is review-approved, waiting on labels. Your +212 on the same two files conflicts with it either way it merges. My suggestion: rebase on top of #1227 once it lands and adapt the archive path to the seam. Since your patch adds no Bun calls of its own, it should be a mostly mechanical adaptation, and I am happy to help with that rebase.
-
New suite extension. plugin/opencode convention is the .mts + .mjs pair; the new engram.test.ts (337 lines) is a third variant. Worth knowing: no CI job currently runs any plugin/opencode suite (only plugin/pi has a wired job; pre-existing gap, not your fault). Aligning to the pair, or wiring a job for them, keeps the suites from drifting silently.
-
Size. +1367 crosses the org's 400 changed-line review budget. The store/sync safeguards are in scope per the acceptance criteria, but plugin + store + sync + server landing together is a lot of review surface at once. If maintainers ask for a slice, the natural cut is core safeguards first (store, sync, server), plugin integration second.
Happy to re-check after the rebase.
