Stack 1 of 3. Merge this first. Then #33 (feature), then the docs PR.

What changes

Refactor: shared code never imports a host adapter (ADR-011 is in stack PR 3)

  • Pi's session conversation reader moves from src/adapters/pi/conversation.ts to src/importer/pi-conversation.ts, next to the OpenCode history reader. The Pi adapter imports it from there.
  • isStructuredSummaryPromptMessage, which recognises omms's own prompts on both hosts, moves to src/core/internal-prompt.ts.
  • profile-import.ts uses the core check instead of the OpenCode adapter's isInternalPrompt. The dropped half looked up live OpenCode sessions, which says nothing about imported history.
  • The adapter boundary test now covers src/importer.

Fix: the tag migration touches only untagged memories (TDR-012)

  • The Memory Tagging Migration dialog counted untagged memories, but the run re-embedded every memory in every project shard.
  • A memory that threw never advanced the run, so one bad row could stall it forever.
  • Now it lists untagged memories only, re-embeds only a memory that gains tags, records a failure and moves on, and starts fresh next time.

Chore: CodeRabbit reviews stacked PRs

  • .coderabbit.yaml sets reviews.auto_review.base_branches: [".*"]. By default CodeRabbit reviews only PRs that target main.

Verification

  • bun run ci:local passes on this branch.
  • New regression test tests/tag-migration.test.ts; it fails on the old code.

Summary by CodeRabbit

  • New Features
    • Added keyword filtering to memory lists, matching tags to the trimmed, lowercase search term. When enabled, prompts are limited to those linked to matching memories.
  • Bug Fixes
    • Tag migration now works from a fixed list of untagged memories and skips items that were deleted or tagged before processing.
    • Failed tagging attempts remain untagged for a later run, and embeddings are updated only after tags are saved.
    • Profile imports now exclude structured summary prompts.

Shared code never imports a host adapter; adapters may import shared code.

- Move Pi's session conversation reader from src/adapters/pi/conversation.ts
  to src/importer/pi-conversation.ts, next to the OpenCode history reader.
  The Pi adapter imports it from there for live capture.
- Move isStructuredSummaryPromptMessage, which recognises omms's own
  prompts on both hosts, to src/core/internal-prompt.ts.
- profile-import.ts uses the core check instead of the OpenCode adapter's
  isInternalPrompt. The dropped half looked up live OpenCode sessions, which
  says nothing about imported history.
- The adapter boundary test now covers src/importer.
The Memory Tagging Migration dialog counted untagged memories but the run
re-embedded every memory in every project shard. A memory that threw also
never advanced the run, so one bad row could stall it forever.

The run now builds its list from untagged memories only, re-embeds only a
memory that gains tags, records a failure and moves on, and starts from a
fresh list next time. See TDR-012.

📝 Walkthrough

Walkthrough

The changes add keyword filtering to memory listings and update tag migration to process a fixed queue of untagged memories. They also move Pi conversation imports into the importer layer, centralize structured-prompt classification, and adjust automatic review configuration.

Changes

Tag migration

Layer / File(s) Summary
Queue scope and run state
docs/tdr/*, src/services/api-handlers.ts
TDR-012 documents the migration’s untagged-memory work list and failure handling. Each run creates a queue from memories with null or empty tags.
Queue processing and validation
src/services/api-handlers.ts, tests/tag-migration.test.ts
The handler rechecks queued rows, skips deleted or newly tagged memories, records unsuccessful tagging attempts, and updates vectors after saving tags. Tests cover batching, stored tags, and retries.

Memory listing filters

Layer / File(s) Summary
Keyword filtering in memory listings
src/services/api-handlers.ts
The listing handler accepts an optional keyword, matches it exactly against normalized tags, and includes prompts linked to matching memories.

Importer boundary and prompt classification

Layer / File(s) Summary
Importer-owned Pi conversation reader
AGENTS.md, src/importer/*, src/adapters/pi/*, tests/pi-adapter-boundary.test.ts, tests/pi-conversation.test.ts
Pi conversation imports now resolve through the importer module. The boundary test checks importer files for adapter references.
Shared structured-prompt classification
src/core/internal-prompt.ts, src/adapters/opencode/user-prompt.ts, src/importer/profile-import.ts
The core module defines the structured-prompt predicate. The OpenCode adapter re-exports it, and profile import uses it to filter prompts.

Automatic review configuration

Layer / File(s) Summary
Automatic reviews for all base branches
.coderabbit.yaml
The configuration declares its schema and sets the base-branch pattern to match any branch.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to b5b50

A failed migration can leave memories with stale search vectors that later runs skip. Profile imports may also include internal prompts, and keyword requests return unfiltered listings. Resolve the migration write ordering before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to b5b50

A failed migration can mark a memory as tagged before its search vectors are updated, then leave it out of future migration runs. Overlapping batch requests may also misreport progress. The affected work is limited to the configured project-memory stores, and no new unauthenticated endpoint was identified.

Retained concerns

  • Medium · reliability · inferred: If embedding or vector storage fails after tags are saved, the memory remains tagged with vectors that were not updated. The new untagged-only queue excludes it from subsequent repair runs.
  • Medium · reliability · inferred: Overlapping batch requests can operate on a shared queue while another request replaces its progress state. An in-flight batch can then advance the replacement run’s cursor, potentially skipping work or reporting completion inaccurately.
Security review details

Security Blast Radius

  • observed — The changed migration constructs its own IDs and shard paths from untagged rows in configured project shards; an HTTP caller supplies batch size, not target IDs or paths. A batch request must pass the existing API authentication gate.

Trust Boundaries and Controls

  • observed — The server checks API credentials before dispatch. The migration re-reads queued rows and skips deleted or newly tagged rows, but does not condition its later tag write on the row still being unchanged after the model call.

Resilience and Maintainability Implications

  • inferred — The principal PR-specific integrity risk is incomplete recovery of persistent tag/vector state, rather than a demonstrated authentication bypass. The absence of a documented single-caller deployment constraint leaves the shared queue’s concurrency behavior uncertain.

Hardening Proposals

  • proposed — Make tag eligibility and vector completion one recoverable transition, or retain an explicit incomplete state that a later run can repair.
  • proposed — Serialize or atomically claim migration batches before advancing shared progress, and bound the caller-provided batch size. Batch-size validation would also harden an input that was already unbounded on the base branch.

Review comments at @src/importer/profile-import.ts:
- Line 81: Preserve exclusion of internal sessions when `session.title` is
unavailable; `readSessions` currently disables that filter, allowing unmarked
prompts through `importProfileFromHistory`. Keep the session-ID check in a
host-neutral location before importing the profile, or reject schemas missing
the required title column; retain `isStructuredSummaryPromptMessage` behavior
for other prompts.

Review comments at @src/services/api-handlers.ts:
- Around line 1535-1539: Update the tag migration flow around `embedWithTimeout`
to compute both embeddings before any database writes, then apply the tag and
vector changes in one write transaction. Update `tursoVectorSearch.updateVector`
to accept and use that transaction object so a vector-update failure rolls back
the tag change.
- Around line 154-155: Update the memory-listing route to read the keyword query
parameter and pass it as the fifth argument to handleListMemories, preserving
the existing behavior when no keyword is provided.

A failed embedding left a memory tagged with stale vectors, and later
runs skipped it because it was no longer untagged.
