Summary

Problem

Solution

  • mStatusGen moves above the read effect. The read captures it when it starts and returns without writing when gen !== mStatusGen.current. A start or retry since then owns the status, and the run's end reads again.

Submission Checklist

  • Tests added or updated (MemoryImportBanner.test.tsx): drops a read still pending when the user starts the move drives that exact order (run ends, slow read, start, read answers last), and keeps the offer when a stale read fails after a failed start covers the read's failure path.
  • Diff coverage ≥ 80%: left to CI (no local runs); the new branch is exercised by the test above.
  • Coverage matrix updated: N/A, behaviour-only change within row 8.2.11.
  • All affected feature IDs from the matrix are listed in the PR description under ## Related.
  • No new external network dependencies introduced: mocked API facade only.
  • Manual smoke checklist: N/A, no release-cut surface change.
  • Linked issue: N/A, no tracking issue; this comes from review threads on fix(memory): bump tinymemory to v1.23.7; the memory banner drops stale migration reads #7113/fix(memory): import in accepted batches, waiting once at the end #7114.

Impact

  • Desktop UI only, in the Memory page's banner. No core or RPC change.

Revert-check (described, not built locally): remove the gen !== mStatusGen.current check in the read's .then, and drops a read still pending when the user starts the move fails (the offer comes back over the running move).

Behavior Changes

  • Intended behavior change: no read of the move's state can overwrite a newer start or retry.
  • User-visible effect: no flicker back to "Migrate now" after starting while a read is pending.

Summary by CodeRabbit

  • Bug Fixes
    • Kept migration status accurate when an outdated response arrives after a migration starts or is retried, preventing stale results from overriding the current state.
    • Preserved the migration offer when an outdated scan failure arrives after a migration attempt fails. Status and import options now continue to reflect the latest action rather than delayed scan or status results.

The poll was guarded by the start generation, but the shared read (at
mount, after a failure, when a run ends, when the import finishes) was
not: one still pending when the user started the move wrote its earlier
idle status over the running one. The read now captures the generation
and drops its answer when a start or retry happened meanwhile.

security

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: The stale scan and poll responses are now generation-gated, including their error paths, so obsolete requests cannot overwrite current migration state. The change looks safe to merge. _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

tests

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: The change extends the status generation guard to the scan/read effect and adds two tests that would fail if stale reads overwrote newer state; the previously raised gap about dropping errors from obsolete scan requests is now fixed by the `gen === mStatusGen.current` guard in the catch path. The tests exercise real UI outcomes, not mocks. Looks sound. _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

description

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: The change moves `mStatusGen` above the shared read effect and makes both its success and failure paths drop answers superseded by a start or retry, exactly as described, with tests covering both orders. The earlier finding about obsolete scan errors being applied is fixed by the same `gen === mStatusGen.current` guard in the catch path. The description accurately matches the diff; this looks sound to merge. _Code retrieval was unavailable (model: ladder embeddings returned 400 Bad Request: {"error":{"message":"unknown ladder vectors; known ladders are flash (also chat-v1, flash-v1), instant (also no-think, instant-v1), reasoning (also deepseek), max-reasoning (also max-reasoning-v1), deepseek-flash (also reasoning-v1, agentic-v1), deep (also luna), scribe, uncensored, vectors-oai3 (also embeddings-oai3-v1), vision (also vision-v1, multimodal-v1), image (also images-v1, image-v1), vi), so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

e2e

  • Conclusion: Neutral
  • Scope reviewed: all assigned evidence
  • Lane summary: This change hardens the memory migration banner against stale scan/status answers, an internal race fix with no new external surface; it is covered by the component's unit tests and the e2e candidates are lexical coincidences. The earlier finding about dropped errors from obsolete scan requests is fixed by the new generation check on the error path. No blocking findings.

📝 Walkthrough

Walkthrough

Migration scan results are ignored when a migration start or retry changes the status generation while a scan is pending. Regression tests cover stale successful and failed responses.

Changes

Migration status handling

Layer / File(s) Summary
Guard stale migration scan results
app/src/components/memory/MemoryImportBanner.tsx, app/src/components/memory/MemoryImportBanner.test.tsx
The scan snapshots the status generation and ignores successful or failed results if a start or retry changes it. Tests verify that stale responses do not replace the running state or remove the migration offer.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix · Severity of issue fixed: Low

Suggested reviewers: codeghost21

Merge Risk: ⚪ Minimal · up to 3f785

This change stops a late, out-of-date read from restoring the "Migrate now" offer over a running migration. It also stops a stale failure from hiding the offer after a failed start. It is limited to the Memory page banner and includes tests, so no merge-blocking risk is evident.

A rabbit checks the scan’s reply,
And lets stale status pass it by.
The running move stays on its track,
The offer waits; the test looks back.
Two late responses lose their say,
The rabbit hops to greet the day.

A read made obsolete by a start or retry dropped its answer, but its
failure still cleared the scan and scheduled a retry, hiding the offer
for a retry interval after a failed start.
