+# Merged-Worktree Adoption
+
+**Goal**: When a worktree's branch is merged into its parent, the worktree's observations become part of the parent project's observation list — without data movement, destructive schema changes, or lost provenance.
+
+**Approach**: Add a nullable `merged_into_project` column to observations and session_summaries, extend query predicates with `OR merged_into_project = :parent`, propagate the same metadata to Chroma embeddings for semantic-search consistency, detect merges via git (authoritative), run adoption automatically on worker startup, and offer a CLI escape hatch for squash-merges.
+
+**Key design decisions**:
+- `observations.project` is **immutable provenance** — never overwritten.
+- Merged-status is a **virtual pointer**, not a data move.
+- **Chroma metadata stays in lockstep with SQLite** (full consistent sync, not lazy SQL expansion). Single source of truth per row.
+- Detection is **git-authoritative** (`git worktree list --porcelain` + `git branch --merged`), with a manual CLI override for squash-merges.
+
+---
+
+## Phase 0 — Documentation Discovery (COMPLETE)
+
+Findings consolidated from three parallel discovery subagents. The following are the ONLY APIs/patterns to copy from. Do not invent alternatives.
+
+### Allowed APIs (copy from these locations)
+
+| Need | File | Lines | What to copy |
+|---|---|---|---|
+| Migration idempotency via marker file | `src/services/infrastructure/ProcessManager.ts` | 680–830 | `runOneTimeCwdRemap` structure, marker file pattern `.cwd-remap-applied-v1` |
+| Worker startup wiring | `src/services/worker-service.ts` | 363–365 | Call site inside `initializeBackground()`, invoked before `dbManager.initialize()` |
+| `ALTER TABLE ADD COLUMN` idempotency | `src/services/sqlite/migrations/runner.ts` | 131–141 | `PRAGMA table_info(<table>)` guard before `ALTER TABLE ... ADD COLUMN` |
+| Column addition example | `src/services/sqlite/migrations/runner.ts` | 495 | `db.run('ALTER TABLE observations ADD COLUMN discovery_tokens INTEGER DEFAULT 0')` |
+| Observations schema | `src/services/sqlite/migrations/runner.ts` | 82–96 | Existing columns + indices (do not duplicate) |
+| `schema_versions` marker table | `src/services/sqlite/migrations/runner.ts` | 51–58 | `INSERT OR IGNORE INTO schema_versions ...` — used only when numbered migration |
+| Logger | `src/utils/logger.ts` | 18 | Components: `SYSTEM`, `DB`, `CHROMA_SYNC`. Use `logger.info/warn/error('SYSTEM', ...)` |
+| Worktree detection | `src/utils/worktree.ts` | 1–84 | `detectWorktree(cwd): WorktreeInfo { isWorktree, worktreeName, parentRepoPath, parentProjectName }` |
+| Project-name derivation | `src/utils/project-name.ts` | 73–119 | `getProjectContext(cwd): ProjectContext { primary, parent, isWorktree, allProjects }` |
+| Multi-project read (WHERE to extend) | `src/services/context/ObservationCompiler.ts` | 111–160 | `queryObservationsMulti` — `WHERE o.project IN (${projectPlaceholders})` |
+| Same, for summaries | `src/services/context/ObservationCompiler.ts` | 168–196 | Parallel summary-fetching query with `ss.project IN (...)` |
+| Context injection endpoint | `src/services/worker/http/routes/SearchRoutes.ts` | 211–253 | `handleContextInject` wires `projects` comma-separated query param into `generateContext` |
+| Context entry point | `src/services/context/ContextBuilder.ts` | 126–183 | `generateContext()` picks `queryObservationsMulti` when `projects.length > 1` |
+| Chroma metadata attach (observations) | `src/services/sync/ChromaSync.ts` | 132–140 | `baseMetadata` object — includes `project`, `sqlite_id`, etc. This is where `merged_into_project` is added. |
+| Chroma collection architecture | `src/services/sync/ChromaSync.ts` | 806 (comment) | **Single shared collection `cm__claude-mem`**, scoped by metadata. Do NOT create a per-merged collection. |
+| Chroma filter build (read side) | `src/services/sync/SearchManager.ts` | 174–177 | `whereFilter = { project: options.project }` — extended with `$or` in Phase 3 |
+| Chroma update API | `src/services/sync/ChromaSync.ts` (grep) | — | `chroma_update_documents` via MCP — used by existing sync flows |
+| CLI entrypoint switch | `src/npx-cli/index.ts` | 28–169 | Plain `switch (command)`, dynamic `import()` of `./commands/<name>.ts`. No commander/cac. |
+| Admin-script template | `scripts/cwd-remap.ts` | 1–186 | Bun shebang, argv parsing, `--apply` gate, dry-run default |
+| UI observation card | `src/ui/viewer/components/ObservationCard.tsx` | 58 | `<span className="card-project">{observation.project}</span>` — where the merged badge is added |
+
+### Anti-patterns (do NOT do these)
+
+- Do NOT overwrite `observations.project` or `session_summaries.project`. These are immutable provenance.
+- Do NOT create a new Chroma collection for merged observations. Deployment uses a single shared `cm__claude-mem` collection.
+- Do NOT introduce a `gh` CLI dependency. Codebase has no `gh` usage outside `.github/workflows/`. Use `git` subprocesses only.
+- Do NOT use SQLite's unsupported `ALTER TABLE ... ADD COLUMN IF NOT EXISTS` syntax. Use the `PRAGMA table_info` guard instead.
+- Do NOT use a CLI framework (commander, cac, yargs). The codebase uses hand-rolled `switch (command)` + `process.argv.slice(2)`.
+- Do NOT mutate `ProjectContext.allProjects` to inject merged children. The reverse lookup lives in the SQL/Chroma query predicates, not in `ProjectContext`.
+- Do NOT run the lazy "SQL-expand projects then filter Chroma" approach. We want Chroma metadata to be the authoritative filter for semantic search.
+
+---
+
+## Phase 1 — Schema migration
+
+**What to implement**: One nullable column + one index on each of `observations` and `session_summaries`. Idempotent via `PRAGMA table_info` guard.
+
+### Files touched
+
+- `src/services/sqlite/migrations/runner.ts`
+
+### Implementation
+
+Add a new method `ensureMergedIntoProjectColumns()` on `MigrationRunner`, modeled on the pattern at lines 131–141:
+
+```typescript
+private ensureMergedIntoProjectColumns(): void {
+  const obsCols = this.db
+    .query('PRAGMA table_info(observations)')
+    .all() as TableColumnInfo[];
+  if (!obsCols.some(c => c.name === 'merged_into_project')) {
+    this.db.run('ALTER TABLE observations ADD COLUMN merged_into_project TEXT');
+    this.db.run(
+      'CREATE INDEX IF NOT EXISTS idx_observations_merged_into ON observations(merged_into_project)'
+    );
+  }
+
+  const sumCols = this.db
+    .query('PRAGMA table_info(session_summaries)')
+    .all() as TableColumnInfo[];
+  if (!sumCols.some(c => c.name === 'merged_into_project')) {
+    this.db.run('ALTER TABLE session_summaries ADD COLUMN merged_into_project TEXT');
+    this.db.run(
+      'CREATE INDEX IF NOT EXISTS idx_summaries_merged_into ON session_summaries(merged_into_project)'
+    );
+  }
+}
+```
+
+Call from `runAllMigrations()` — append immediately after the last existing `ensure*` method so it runs on every worker startup. The `PRAGMA table_info` check is O(1) and makes re-runs cheap.
+
+### Verification
+
+- Start the worker. Migration logs show no error.
+- `sqlite3 ~/.claude-mem/claude-mem.db ".schema observations"` shows `merged_into_project TEXT`.
+- Same for `session_summaries`.
+- Restart worker → no ALTER TABLE error (guard worked).
+- `sqlite3 ~/.claude-mem/claude-mem.db ".indices observations"` lists `idx_observations_merged_into`.
+
+### Anti-pattern guards
+
+- Do NOT use `ALTER TABLE ... ADD COLUMN IF NOT EXISTS` — SQLite does not support it.
+- Do NOT bump `schema_versions` for this migration. That table is for numbered migration history; the column-existence check is self-idempotent.
+
+---
+
+## Phase 2 — Adoption engine (SQLite + Chroma consistent)
+
+**What to implement**: A single function that, given a parent repo path, detects all merged-worktree branches and stamps `merged_into_project` on both SQLite rows AND Chroma metadata in the same logical operation. Reused by worker startup (Phase 4) and CLI (Phase 5).
+
+### Files touched
+
+- `src/services/infrastructure/WorktreeAdoption.ts` (new)
+- `src/services/sync/ChromaSync.ts` — add `updateMergedIntoProject(sqliteIds: number[], mergedIntoProject: string): Promise<void>`
+
+### Public API
+
+```typescript
+export interface AdoptionResult {
+  repoPath: string;
+  parentProject: string;
+  scannedWorktrees: number;
+  mergedBranches: string[];          // branches classified as merged
+  adoptedObservations: number;        // SQLite rows stamped
+  adoptedSummaries: number;
+  chromaUpdates: number;              // Chroma docs patched
+  chromaFailed: number;
+  dryRun: boolean;
+  errors: Array<{ worktree: string; error: string }>;
+}
+
+export async function adoptMergedWorktrees(opts: {
+  repoPath?: string;       // defaults to process.cwd()
+  dataDirectory?: string;  // defaults to DATA_DIR
+  dryRun?: boolean;
+  onlyBranch?: string;     // manual override for squash-merge case
+}): Promise<AdoptionResult>;
+```
+
+### Implementation outline
+
+Mirror `runOneTimeCwdRemap` in `ProcessManager.ts:680–830` for DB lifecycle (open, transaction, finally-close). Add Chroma sync step after SQL commit.
+
+1. **Resolve main repo path**
+   - `const mainRepo = execSync('git rev-parse --git-common-dir', { cwd: opts.repoPath ?? process.cwd() })` — strip `/.git` suffix to get the working tree root.
+   - This pattern is used in `scripts/cwd-remap.ts:48–51`. Copy that handling verbatim.
+
+2. **Resolve parent project name**
+   - `const parentProject = getProjectContext(mainRepo).primary` — imported from `src/utils/project-name.ts`.
+
+3. **Enumerate worktrees**
+   - `git -C <mainRepo> worktree list --porcelain` → parse `worktree <path>`, `branch refs/heads/<name>` lines.
+   - Filter out the main worktree entry (its path equals `mainRepo`).
+
+4. **Classify as merged**
+   - If `opts.onlyBranch` provided: include only that branch (squash-merge escape hatch).
+   - Else: `git -C <mainRepo> branch --merged HEAD --format='%(refname:short)'` → intersect with worktree branch list.
+
+5. **Resolve worktree project names**
+   - For each merged worktree path, `const worktreeProject = getProjectContext(worktreePath).primary` → yields the composite `parent/worktree` name.
+
+6. **SQL transaction** (model on `ProcessManager.ts:745–760, 808`)
+   - Open DB via `new Database(dbPath)` (manage own handle — must close before `dbManager.initialize()` runs).
+   - For each merged worktree:
+     - `SELECT id FROM observations WHERE project = ? AND merged_into_project IS NULL` → collect sqlite IDs to later push to Chroma.
+     - `UPDATE observations SET merged_into_project = ? WHERE project = ? AND merged_into_project IS NULL`.
+     - Same for `session_summaries`.
+   - Commit transaction.
+   - If `dryRun`, roll back instead.
+
+7. **Chroma metadata sync** (full consistent — NOT lazy)
+   - For the set of sqlite IDs just stamped, call `ChromaSync.updateMergedIntoProject(sqliteIds, parentProject)`.
+   - `ChromaSync.updateMergedIntoProject` implementation:
+     ```typescript
+     async updateMergedIntoProject(sqliteIds: number[], mergedIntoProject: string): Promise<void> {
+       if (sqliteIds.length === 0) return;
+       // Batch: look up Chroma doc IDs via metadata filter on sqlite_id, then patch.
+       const where = { sqlite_id: { $in: sqliteIds } };
+       const existing = await chromaMcp.callTool('chroma_get_documents', {
+         collection_name: this.collectionName,
+         where,
+         include: ['metadatas']
+       });
+       const docIds: string[] = existing.ids ?? [];
+       const metadatas: Record<string, unknown>[] = (existing.metadatas ?? []).map(m => ({
+         ...m,
+         merged_into_project: mergedIntoProject
+       }));
+       if (docIds.length === 0) return;
+       await chromaMcp.callTool('chroma_update_documents', {
+         collection_name: this.collectionName,
+         ids: docIds,
+         metadatas
+       });
+     }
+     ```
+   - On Chroma error: log via `logger.error('CHROMA_SYNC', ...)`, increment `chromaFailed`, but do NOT roll back SQL. SQL is source of truth; a subsequent run will retry the Chroma patch (idempotent — metadata set to same value is a no-op).
+
+8. **Logging**
+   - `logger.info('SYSTEM', 'Worktree adoption applied', { parentProject, adoptedObservations, adoptedSummaries, chromaUpdates, chromaFailed, mergedBranches })`.
+   - On per-worktree error: `logger.warn('SYSTEM', 'Worktree adoption skipped branch', { worktree, error })` — collect in `errors[]`, continue.
+
+9. **Re-adoption safety net**
+   - Because Chroma updates can fail independently, add a secondary SQL-side reconciliation: on each adoption run, also find `observations WHERE merged_into_project IS NOT NULL` whose Chroma metadata lacks the field. Run the same `updateMergedIntoProject` on that delta.
+   - Keep this bounded: only reconcile rows adopted in the last N days (e.g. 30) to avoid full-table scans.
+
+### Verification
+
+- Dry-run against a repo with one known-merged worktree: result shows correct `adoptedObservations`, DB unchanged, no Chroma writes.
+- Real run: `SELECT COUNT(*) FROM observations WHERE merged_into_project IS NOT NULL` matches `adoptedObservations`.
+- Chroma: `chroma_get_documents` with `where: { merged_into_project: 'claude-mem' }` returns the same row count.
+- Re-run: `adoptedObservations = 0`, `chromaUpdates = 0` (both idempotent).
+- Simulate Chroma outage (stop chroma): adoption logs `CHROMA_SYNC` error, `chromaFailed > 0`, SQL still stamps. Next run with Chroma back up reconciles the delta.
+
+### Anti-pattern guards
+
+- Do NOT rollback SQL on Chroma failure. SQL is authoritative; Chroma is a derived index.
+- Do NOT call Chroma per-row. Batch by sqlite_id set to minimize round-trips.
+- Do NOT adopt branches not in `git branch --merged HEAD` unless `onlyBranch` override is explicit.
+- Do NOT touch observations whose `project` is not a composite worktree name. The worktree-name match is the safety gate.
+- Do NOT skip the `merged_into_project IS NULL` clause on UPDATE — this is what makes the run idempotent.
+
+---
+
+## Phase 3 — Query plumbing (SQLite + Chroma $or)
+
+**What to implement**: Extend the two multi-project read queries in `ObservationCompiler.ts` and the Chroma filter in `SearchManager.ts` to treat `merged_into_project` as a second match axis. Direct Chroma `$or` filter — no SQL-side expansion dance.
+
+### Files touched
+
+- `src/services/context/ObservationCompiler.ts`
+- `src/services/sync/SearchManager.ts`
+
+### 3a. SQLite WHERE-clause extension
+
+`src/services/context/ObservationCompiler.ts:111–160` (`queryObservationsMulti`): change
+
+```sql
+WHERE o.project IN (${projectPlaceholders})
+```
+
+to
+
+```sql
+WHERE (o.project IN (${projectPlaceholders})
+       OR o.merged_into_project IN (${projectPlaceholders}))
+```
+
+Double-bind the `projects` array:
+
+```typescript
+.all(
+  ...projects,          // for o.project IN (...)
+  ...projects,          // for o.merged_into_project IN (...)
+  ...typeArray,
+  ...conceptArray,
+  ...(platformSource ? [platformSource] : []),
+  config.totalObservationCount
+)
+```
+
+`src/services/context/ObservationCompiler.ts:168–196` (summary variant): apply the same extension, using `ss.merged_into_project`.
+
+### 3b. Chroma filter extension
+
+`src/services/sync/SearchManager.ts:174–177`:
+
+```typescript
+if (options.project) {
+  const projectFilter = {
+    $or: [
+      { project: options.project },
+      { merged_into_project: options.project }
+    ]
+  };
+  whereFilter = whereFilter
+    ? { $and: [whereFilter, projectFilter] }
+    : projectFilter;
+}
+```
+
+When `options.project` is an array (if that path exists — grep first), build a flat `$or` over both fields × all requested projects.
+
+### 3c. New-observation Chroma metadata
+
+`src/services/sync/ChromaSync.ts:132–140` — extend `baseMetadata`:
+
+```typescript
+const baseMetadata: Record<string, string | number | null> = {
+  sqlite_id: obs.id,
+  doc_type: 'observation',
+  memory_session_id: obs.memory_session_id,
+  project: obs.project,
+  merged_into_project: obs.merged_into_project ?? null,  // NEW
+  created_at_epoch: obs.created_at_epoch,
+  type: obs.type || 'discovery',
+  title: obs.title || 'Untitled'
+};
+```
+
+This makes every new observation Chroma-compatible with the Phase 3b filter from the first sync. For existing rows, Phase 2's adoption engine patches metadata retroactively.
+
+**Check Chroma metadata type constraints**: Chroma rejects `null` in metadata — confirm via a quick test. If `null` is rejected, OMIT the field when unset (use `if (obs.merged_into_project) baseMetadata.merged_into_project = obs.merged_into_project;`).
+
+### 3d. ContextBuilder compatibility check
+
+`src/services/context/ContextBuilder.ts:126–183` — no change needed. `projects = input?.projects ?? context.allProjects` stays as-is; the extended WHERE clause in Phase 3a does all the work.
+
+### Verification
+
+- Before adoption: context-inject API for `claude-mem` returns N observations.
+- After adoption of `claude-mem/dar-es-salaam`: API returns N + M (M = count of dar-es-salaam's own observations).
+- Semantic search via Chroma (`/search` endpoint or MCP) with `project=claude-mem` returns dar-es-salaam-origin rows too.
+- Worktree-local queries (`projects=[claude-mem, claude-mem/dar-es-salaam]`) still return `[parent + own]` unchanged.
+- SQL EXPLAIN on the extended WHERE shows it uses `idx_observations_project` OR `idx_observations_merged_into` (both indices hit).
+
+### Anti-pattern guards
+
+- Do NOT lose the `o.project` filter — it's still required (merged-row predicate is additive, not a replacement).
+- Do NOT forget to double-bind `projects` in the prepared statement — placeholder count must match argument count.
+- Do NOT add a subquery or JOIN for merged discovery. A flat `OR` + index is faster.
+- Do NOT write `null` into Chroma metadata if Chroma rejects it. Use the "omit if unset" pattern.
+
+---
+
+## Phase 4 — Automatic trigger on worker startup
+
+**What to implement**: Call `adoptMergedWorktrees()` during worker startup, immediately after `runOneTimeCwdRemap()`. **Not** marker-gated — it runs every worker startup because git state evolves and the engine is idempotent.
+
+### Files touched
+
+- `src/services/worker-service.ts`
+
+### Implementation
+
+Import alongside existing `ProcessManager` imports at lines 41–53:
+
+```typescript
+import { adoptMergedWorktrees } from './infrastructure/WorktreeAdoption.js';
+```
+
+Insert immediately after the existing `runOneTimeCwdRemap()` call at lines 363–365:
+
+```typescript
+runOneTimeCwdRemap();
+
+try {
+  const result = await adoptMergedWorktrees({});
+  if (result.adoptedObservations > 0 || result.chromaUpdates > 0) {
+    logger.info('SYSTEM', 'Merged worktrees adopted on startup', result);
+  }
+  if (result.errors.length > 0) {
+    logger.warn('SYSTEM', 'Worktree adoption had per-branch errors', { errors: result.errors });
+  }
+} catch (err) {
+  logger.error('SYSTEM', 'Worktree adoption failed (non-fatal)', {}, err as Error);
+}
+```
+
+**DB lifecycle note**: `adoptMergedWorktrees` must manage its own DB handle (open + close) before `dbManager.initialize()` runs at line 380. Mirror `runOneTimeCwdRemap`'s finally-block pattern.
+
+### Verification
+
+- Restart worker. Log shows "Merged worktrees adopted on startup" only on first run after a new merge lands.
+- Subsequent restarts log nothing (idempotent).
+- Simulate adoption exception (e.g., rename git temporarily): log shows error, worker startup continues successfully.
+- Build-and-sync restart picks up new merges without manual intervention.
+
+### Anti-pattern guards
+
+- Do NOT block worker startup on adoption failure. Wrap in try/catch; swallow + log.
+- Do NOT run adoption after `dbManager.initialize()`. The engine manages its own DB handle; two handles at once risk lock contention.
+- Do NOT await Chroma sync before returning SQL success. Internally, yes; but don't make worker startup hang on Chroma I/O — cap with a reasonable timeout inside the engine.
+
+---
+
+## Phase 5 — CLI escape hatch
+
+**What to implement**: `claude-mem adopt [--branch <name>] [--dry-run]` — covers squash-merge where `git branch --merged` returns nothing, and provides a manual override for any adoption run.
+
+### Files touched
+
+- `src/npx-cli/commands/adopt.ts` (new)
+- `src/npx-cli/index.ts` (add `case 'adopt'`)
+- `scripts/adopt-worktrees.ts` (new, optional — admin script for bulk ops)
+
+### 5a. Command module
+
+`src/npx-cli/commands/adopt.ts` — follow shape of sibling commands (dynamic-imported by the switch):
+
+```typescript
+import pc from 'picocolors';
+import { adoptMergedWorktrees } from '../../services/infrastructure/WorktreeAdoption.js';
+
+export interface AdoptCommandOptions {
+  dryRun?: boolean;
+  onlyBranch?: string;
+}
+
+export async function runAdoptCommand(opts: AdoptCommandOptions): Promise<void> {
+  const result = await adoptMergedWorktrees({
+    dryRun: opts.dryRun,
+    onlyBranch: opts.onlyBranch
+  });
+
+  console.log(pc.bold(`\nWorktree adoption ${result.dryRun ? pc.yellow('(dry-run)') : pc.green('(applied)')}`));
+  console.log(`  Parent project:         ${result.parentProject}`);
+  console.log(`  Worktrees scanned:      ${result.scannedWorktrees}`);
+  console.log(`  Merged branches:        ${result.mergedBranches.join(', ') || '(none)'}`);
+  console.log(`  Observations adopted:   ${result.adoptedObservations}`);
+  console.log(`  Summaries adopted:      ${result.adoptedSummaries}`);
+  console.log(`  Chroma docs updated:    ${result.chromaUpdates}`);
+  if (result.chromaFailed > 0) {
+    console.log(pc.yellow(`  Chroma sync failures:   ${result.chromaFailed} (will retry on next run)`));
+  }
+  for (const err of result.errors) {
+    console.log(pc.red(`  ! ${err.worktree}: ${err.error}`));
+  }
+}
+```
+
+### 5b. CLI switch
+
+`src/npx-cli/index.ts` — add between existing cases, following the pattern at lines 28–169:
+
+```typescript
+case 'adopt': {
+  const dryRun = args.includes('--dry-run');
+  const branchIndex = args.indexOf('--branch');
+  const onlyBranch = branchIndex !== -1 ? args[branchIndex + 1] : undefined;
+  const { runAdoptCommand } = await import('./commands/adopt.js');
+  await runAdoptCommand({ dryRun, onlyBranch });
+  break;
+}
+```
+
+### 5c. Admin script (optional)
+
+`scripts/adopt-worktrees.ts` — Bun shebang script for users without the plugin installed. Model on `scripts/cwd-remap.ts:1–186`. Default: dry-run. Pass `--apply` to commit.
+
+### Verification
+
+- `npx claude-mem adopt --dry-run` in a repo with merged worktrees prints what WOULD be adopted without writing.
+- `npx claude-mem adopt` writes + prints counts.
+- `npx claude-mem adopt --branch feature/foo` forces adoption of that branch even if `git branch --merged` doesn't include it (squash case).
+- `bun scripts/adopt-worktrees.ts --apply` equivalent to the CLI.
+- Help text / unknown command still reports the existing error (CLI pattern preserved).
+
+### Anti-pattern guards
+
+- Do NOT require running from the worktree. Detection always resolves up to the common-dir, regardless of cwd.
+- Do NOT default to `--apply`. Dry-run first matches `scripts/cwd-remap.ts` ergonomics.
+- Do NOT introduce `commander`, `yargs`, `cac`. Stay with the existing hand-rolled parser.
+
+---
+
+## Phase 6 — UI surfacing
+
+**What to implement**: When the viewer shows an observation in a parent-project context that originated in a merged worktree, display a "merged from <worktree>" badge so provenance is visible. Keep the original `project` field rendered too.
+
+### Files touched
+
+- `src/ui/viewer/components/ObservationCard.tsx`
+- Type definition for `Observation` — wherever `.project` is declared, add `merged_into_project?: string | null`.
+- Observation serializer on the worker → UI path (grep for `doc_type: 'observation'` or `serializeObservation` to find it).
+- CSS file for ObservationCard styles.
+
+### Implementation
+
+Locate the current label render at `src/ui/viewer/components/ObservationCard.tsx:58`:
+
+```tsx
+<span className="card-project">{observation.project}</span>
+```
+
+Extend to:
+
+```tsx
+<span className="card-project">{observation.project}</span>
+{observation.merged_into_project && (
+  <span className="card-merged-badge" title={`Merged into ${observation.merged_into_project}`}>
+    merged → {observation.merged_into_project}
+  </span>
+)}
+```
+
+Add CSS for `.card-merged-badge` — subtle secondary chip style (muted color, smaller font). Match existing `.card-source` / `.card-project` aesthetics.
+
+### Verification
+
+- After adoption, open viewer at `http://localhost:37777`, select the parent project. Merged observations show both their origin worktree name AND the "merged →" badge.
+- Worktree view (if still addressable) shows no badge (badge only renders when `merged_into_project` is set; a worktree viewing its own observations would not see it, since in that view `merged_into_project` is the PARENT name, not the current project).
+- Hover tooltip shows full target project name.
+
+### Anti-pattern guards
+
+- Do NOT hide merged observations in the parent view. The goal is visibility.
+- Do NOT replace `project` display with `merged_into_project`. Both are meaningful: `project` = origin, `merged_into_project` = current home.
+- Do NOT require a UI setting toggle to show the badge. Default on.
+
+---
+
+## Phase 7 — Verification pass
+
+### Unit tests
+
+- `adoptMergedWorktrees({ dryRun: true })` against a fixture repo with `[merged, unmerged, squash-merged]` worktrees → classification matches expectation.
+- `ChromaSync.updateMergedIntoProject` on an empty `sqliteIds` array → no-op, no Chroma call.
+- Extended `queryObservationsMulti` with a mixed set of `project` and `merged_into_project` matches → returns union, sorted by `created_at_epoch DESC`.
+
+### Integration tests
+
+- Start worker → create synthetic observations under `claude-mem/test-wt` → simulate branch merge (`git merge`) → restart worker → context-inject API for `claude-mem` returns test-wt observations.
+- Same flow with a squash-merge → auto-adoption misses → run `claude-mem adopt --branch test-wt` → API now returns them.
+- Re-run `claude-mem adopt` twice: second run reports `adoptedObservations: 0, chromaUpdates: 0`.
+
+### Anti-pattern grep checks
+
+Run before landing:
+
+```bash
+# No one renamed the project field
+rg "UPDATE observations SET project" src/
+# (Expected: zero hits other than the existing CWD remap)
+
+# Adoption only touches via IS NULL guard
+rg "merged_into_project" src/ -C2
+# (Expected: all UPDATE sites include "IS NULL" predicate)
+
+# CLI registered
+rg "case 'adopt'" src/npx-cli/index.ts
+# (Expected: one hit)
+
+# Chroma metadata extension present
+rg "merged_into_project" src/services/sync/ChromaSync.ts
+# (Expected: hits in baseMetadata and updateMergedIntoProject)
+
+# No gh CLI introduced
+rg "\\bgh\\s+(pr|issue|api)" src/ scripts/
+# (Expected: zero hits outside .github/workflows/)
+```
+
+### Documentation cross-check
+
+- ObservationCompiler WHERE clause matches the shape used by the shipped worktree-reads-parent feature — both clauses symmetric, visible in a single read of the file.
+- Chroma metadata field name `merged_into_project` matches SQLite column name exactly (no `mergedIntoProject`, `merged_project`, etc.).
+- CLI `--branch` flag accepts the same format as worktree composite names.

+## Summary
+
+| Phase | Files touched | New LOC (approx.) |
+|---|---|---|
+| 1. Schema | `src/services/sqlite/migrations/runner.ts` | ~25 |
+| 2. Adoption engine | `src/services/infrastructure/WorktreeAdoption.ts` (new), `src/services/sync/ChromaSync.ts` (new method) | ~200 |
+| 3. Query plumbing | `src/services/context/ObservationCompiler.ts`, `src/services/sync/SearchManager.ts`, `src/services/sync/ChromaSync.ts` | ~40 |
+| 4. Auto-trigger | `src/services/worker-service.ts` | ~15 |
+| 5. CLI | `src/npx-cli/commands/adopt.ts` (new), `src/npx-cli/index.ts`, `scripts/adopt-worktrees.ts` (new) | ~100 |
+| 6. UI | `src/ui/viewer/components/ObservationCard.tsx`, Observation type, serializer, CSS | ~20 |
+| 7. Tests + verification | scattered | — |
+| **Total** | | **~400 LOC** |
+
+**Reversibility**: `UPDATE observations SET merged_into_project = NULL` + a Chroma `update_documents` call with the field omitted restores pre-adoption state completely. Nothing is destroyed.
+
+**Architecture fit**: Mirrors the just-shipped CWD remap migration (`runOneTimeCwdRemap`) for structure, lifecycle, and logging conventions. Chroma metadata sync matches the existing per-observation attach pattern.
+
+**Blast radius**: Zero risk to existing data (no writes to `project` field). Chroma additions are metadata-only (embeddings untouched). Query extensions are additive OR clauses — existing queries still return what they did.

+
+## Fix
+
+**Critical regression fix (#2049): observations no longer save on Claude Code 2.1.109+**
+
+Resolves 100% observation/summary failure on Claude Code 2.1.109+ caused by a latent bug in how the bundled Agent SDK emits the `--setting-sources` flag.
+
+### Root cause
+
+The Agent SDK emits `["--setting-sources", ""]` whenever `settingSources` defaults to `[]`. Our existing Bun-compat filter stripped the empty string but left an orphan `--setting-sources` flag, which then consumed the following `--permission-mode` as its value. Claude Code 2.1.109+ rejects this with:
+
+```
+Error processing --setting-sources:
+  Invalid setting source: --permission-mode.
+```
+
+Every observation SDK spawn crashed with exit code 1 before any data could be written.
+
+### Fix
+
+`ProcessRegistry.createPidCapturingSpawn` now uses a pair-aware filter: when an empty-string arg follows a `--flag`, both are dropped together. The SDK default (no setting sources) is preserved by omission.
+
+### Credits
+
+Thanks to @GigiTiti-Kai for the detailed root-cause report in #2049.
+
+## [12.1.5] - 2026-04-15
+
+Users on v12.1.3 experience 100% observation failure due to empty-string arg filtering corrupting `--setting-sources` on Claude Code 2.1.109+. The fix already landed in v12.1.4 (commit 3d92684 — `fix: filter empty string args before Bun spawn()`). This release forces the update to propagate across npm and the marketplace so every user gets the fix.
+
+## Backlog cleanup
+Also shipped earlier today: the April 2026 backlog consolidation merged 93 PRs and 147 issues into 138 clean tracking issues (95 bugs, 43 feature requests).

+```
+
+## [12.1.4] - 2026-04-15
+
+## Bug Fixes
+
+- **Revert unauthorized $CMEM branding**: A prior Claude instance inserted `$CMEM` token branding into the context injection header during a compression refactor. Reverted back to the original descriptive format: `# [project] recent context, datetime`
+
+## [12.1.3] - 2026-04-15
+
+## What's Changed
+
+### Reverted
+- **Remove overengineered summary salvage logic** (#1850) — Reverts PR #1718 which fabricated synthetic summaries from observation data when the AI returned `<observation>` instead of `<summary>` tags. Missing a summary is preferable to creating a fake one with poorly-mapped fields.

+
+14 community PRs merged + 1 post-merge bug fix. This patch addresses the most impactful bugs across summary persistence, MCP compliance, cross-platform compatibility, and data integrity.
+
+### Highlights
+
+**Summary pipeline fix** — When the LLM returns `<observation>` tags instead of `<summary>` tags (~72% of the time on v12.0.x), data is now salvaged into a synthetic summary instead of being silently discarded. (#1718)
+
+**MCP compliance** — `list_corpora` now returns proper `CallToolResult` objects instead of bare arrays that crashed MCP clients. Search and timeline tools now declare `inputSchema.properties`. (#1701, #1555)
+
+**Data integrity** — Ghost observations with no content fields are now filtered before storage. Search queries are now scoped to the current project via `WHERE project = ?`. (#1676, #1688... wait, #1688 wasn't in this batch)

+## [12.1.0] - 2026-04-09
+
+## Knowledge Agents
+
+Build queryable AI "brains" from your claude-mem observation history. Compile a filtered slice of your past work into a corpus, prime it into a Claude session, and ask questions conversationally — getting synthesized, grounded answers instead of raw search results.
+
+### New Features
+
+- **Knowledge Agent system** — full lifecycle: build, prime, query, reprime, rebuild, delete
+- **6 new MCP tools**: `build_corpus`, `list_corpora`, `prime_corpus`, `query_corpus`, `rebuild_corpus`, `reprime_corpus`
+- **8 new HTTP API endpoints** on the worker service (`/api/corpus/*`)
+- **CorpusBuilder** — searches observations, hydrates full records, calculates stats, persists to `~/.claude-mem/corpora/`
+- **CorpusRenderer** — renders observations into full-detail prompt text for the 1M token context window
+- **KnowledgeAgent** — manages Agent SDK sessions with session resume for multi-turn Q&A
+- **Auto-reprime** — expired sessions are automatically reprimed and retried (only for session errors, not all failures)
+- **Knowledge agent skill** (`/knowledge-agent`) for guided corpus creation
+
+### Security & Robustness
+
+- Path traversal prevention in CorpusStore (alphanumeric name validation + resolved path check)
+- System prompt hardened against instruction injection from untrusted corpus content
+- Runtime name validation on all MCP corpus tool handlers
+- Question field validated as non-empty string
+- Session state only persisted after successful prime (not null on failure)
+- Refreshed session_id persisted after query execution
+- E2e curl wrappers hardened with connect-timeout and transport failure fallback
+
+### Documentation
+
+- New docs page: Knowledge Agents usage guide with Quick Start, architecture diagram, filter reference, and API reference
+- Knowledge agent skill page with workflow examples
+- Added to docs navigation
+
+### Testing
+
+- Comprehensive e2e test suite (31 tests) covering full corpus lifecycle
+
+**Full Changelog**: https://github.com/thedotmack/claude-mem/compare/v12.0.1...v12.1.0

+## [12.0.1] - 2026-04-08
+
+## 🔴 Hotfix: MCP server crashed with `Cannot find module 'bun:sqlite'` under Node
+
+v12.0.0 shipped a broken MCP server bundle that crashed on the very first `require()` call because a transitive import pulled `bun:sqlite` (a Bun-only module) into a bundle that runs under Node. Every MCP-only client (Codex and any flow that boots the MCP tool surface) was completely broken on v12.0.0.
+
+### Root cause
+
+`src/servers/mcp-server.ts` imported `ensureWorkerStarted` from `worker-service.ts`, which transitively pulled in `DatabaseManager` → `bun:sqlite`. The bundle ballooned from ~358KB (v11.0.1) to ~1.96MB (v12.0.0) and `node mcp-server.cjs` immediately threw `Error: Cannot find module 'bun:sqlite'`.
+
+### Fix
+
+- **Extracted** `ensureWorkerStarted` and Windows spawn-cooldown helpers into a new lightweight `src/services/worker-spawner.ts` module that has zero database/SQLite/ChromaDB imports
+- **Wired** `mcp-server.ts` and `worker-service.ts` through the new module via a thin back-compat wrapper
+- **Fixed** `resolveWorkerRuntimePath()` to find Bun on every platform (not just Windows) so the MCP server running under Node can correctly spawn the worker daemon under Bun
+- **Added** two build-time guardrails in `scripts/build-hooks.js`:
+  - Regex check: fails the build if `mcp-server.cjs` ever contains a `require("bun:*")` call
+  - Bundle size budget: fails the build if `mcp-server.cjs` exceeds 600KB
+- **Improved** error messages when Bun cannot be located (now names the install URL and explains *why* Bun is required)
+- **Validated** `workerScriptPath` at the spawner entry point with empty-string and existsSync guards
+- **Memoized** `resolveWorkerRuntimePath()` to skip repeated PATH lookups during crash loops, while never caching the not-found result so a long-running MCP server can recover if Bun is installed mid-session
+
+### Verification
+
+- `node mcp-server.cjs` exits cleanly under Node
+- JSON-RPC `initialize` + `tools/list` + `tools/call search` all succeed end-to-end
+- Bundle is back to ~384KB with zero `require("bun:sqlite")` calls
+- 47 unit tests pass (44 ProcessManager + 3 worker-spawner)
+- Both build guardrails verified to trip on simulated regressions
+- Smoke test: MCP server serves the full 7-tool surface
+
+### What this means for users
+
+- **MCP-only clients (Codex, etc.):** v12.0.0 was broken; v12.0.1 restores full functionality
+- **Claude Code users:** worker startup via the SessionStart hook continued working under Bun on v12.0.0, but the MCP tool surface (`mem-search`, `timeline`, `get_observations`, `smart_*`) was unreliable. v12.0.1 fixes that completely.
+- **Plugin developers:** new build-time guardrails prevent this regression class from shipping again

+
+## [12.0.0] - 2026-04-07
+
+# claude-mem v12.0.0
+
+A major release delivering intelligent file-read gating, expanded language support for smart-explore, platform source isolation, and 40+ bug fixes across Windows, Linux, and macOS.
+
+## Highlights
+
+### File-Read Decision Gate
+Claude Code now intelligently gates redundant file reads. When a file has prior observations in the timeline, the PreToolUse hook injects the observation history and blocks the read — saving tokens and keeping context focused. The gate supports both `Read` and `Edit` tools, uses `permissionDecision` deny with a rich timeline payload, and includes file-size thresholds and observation deduplication.
+
+### Smart-Explore: 24 Language Support
+The `smart-explore` skill now supports **24 programming languages** via tree-sitter AST parsing: TypeScript, JavaScript, Python, Rust, Go, Java, C, C++, C#, Ruby, PHP, Swift, Kotlin, Scala, Bash, CSS, SCSS, HTML, Lua, Haskell, Elixir, Zig, TOML, and YAML. User-installable grammars with `--legacy-peer-deps` support for tree-sitter version conflicts.
+
+### Platform Source Isolation
+Claude and Codex sessions are now fully isolated with `platform_source` column on `sdk_sessions`. Each platform gets its own session namespace, preventing cross-contamination between different AI coding tools. Normalized at route boundaries for consistent behavior.
+
+### Codex & OpenClaw Support
+- Codex plugin manifest added for marketplace discoverability
+- OpenClaw: `workerHost` config for Docker deployments
+- OpenClaw: handle stale `plugins.allow` and non-interactive TTY in installer
+
+## New Features
+
+- **File-read decision gate** — blocks redundant file reads with observation timeline injection (#1564, #1629, #1641)
+- **24-language smart-explore** — AST-based code exploration across all major languages
+- **Platform source isolation** — Claude/Codex session namespacing with DB migration
+- **CLAUDE.local.md support** — `CLAUDE_MEM_FOLDER_USE_LOCAL_MD` setting for writing to local-only config
+- **OpenClaw workerHost** — Docker deployment support for OpenClaw plugin
+- **Codex plugin manifest** — discoverability in Codex marketplace
+- **File-size threshold** — skip file-read gating for small files
+- **Observation deduplication** — prevent duplicate observations in timeline gate
+
+## Bug Fixes
+
+### Worker & Startup
+- Fix worker startup crash with missing observation columns (#1641)
+- Fix SessionStart hooks failing on cold start due to worker race condition

+- Fix readiness timeout logging on reused-worker path (#1491)
+- Remove dead `USER_MESSAGE_ONLY` exit code that caused SessionStart hook errors
+- Decouple MCP health from loopback self-check
+
+### Data Integrity
+- Fix migration version conflict: `addSessionPlatformSourceColumn` now correctly uses v25
+- Add migration for `generated_by_model` and `relevance_count` columns
+- Wire `generated_by_model` into observation write path
+- Use null-byte delimiter in observation content hash to prevent collisions

+- Normalize `platformSource` at route boundary to prevent filter inconsistencies
+- Escape `filePath` in recovery hints to prevent malformed output
+- Address path safety, SQL injection, and gate scoping in file-read hook
+
+### Windows
+- Fix `isMainModule` CJS branch failure on Bun — add `CLAUDE_MEM_MANAGED` fallback
+- Use `cmd /c` to execute `bun.cmd` on Windows
+- Prefer `bun.cmd` over bun shell script on Windows
+- Add `shell: true` on Windows to spawn bun from npm
+
+### Cross-Platform
+- Replace GNU `sort -V` with POSIX-portable version sort
+- Resolve `node not found` on nvm/homebrew installations
+- Resolve hook failures when `CLAUDE_PLUGIN_ROOT` is not injected (#1533)
+- Fix bun-runner signal exit handling — scope to `start` subcommand only

+- Provide empty JSON fallback when stdin is not piped (#1560)
+
+### Parser & Content
+- Strip `<persisted-output>` tags from memory
+- Strip `<system-reminder>` tags from persisted memory and DRY up regex
+- Skip `parseSummary` false positives with no sub-tags (#1360)
+- Handle bare filenames in `regenerate-claude-md.ts` (#1514)

-## The 3-Month Battle Against Complexity
-
-**TL;DR:** For three months, Claude's instinct to add code instead of delete it caused the same bugs to recur. What should have been 5 lines of code became ~1000 lines, 11 useless methods, and 7+ failed "fixes." The timestamp corruption that finally broke things was just a symptom. The real achievement: **984 lines of code deleted.**
-
----
-
-## What Actually Happened
-
-Every Claude Code hook receives a session ID. That's all you need.
-
-But Claude built an entire redundant session management system on top:
-- An `sdk_sessions` table with status tracking, port assignment, and prompt counting
-- 11 methods in `SessionStore` to manage this artificial complexity
-- Auto-creation logic scattered across 3 locations
-- A cleanup hook that "completed" sessions at the end
-
-**Why?** Because it seemed "robust." Because "what if the session doesn't exist?" 
-
-But the edge cases didn't exist. Hooks ALWAYS provide session IDs. The "defensive" code was solving imaginary problems while creating real ones.
-
----
-
-## The Pattern of Failure
-
-Every time a bug appeared, Claude's instinct was to **ADD** more code:
-
-| Bug | What Claude Added | What Should Have Happened |
-|-----|------------------|--------------------------|
-| Race conditions | Auto-create fallbacks | Delete the auto-create logic |
-| Duplicate observations | Validation layers | Delete the code path allowing duplicates |
-| UNIQUE constraint violations | Try-catch with fallbacks | Use `INSERT OR IGNORE` (5 characters) |
-| Session not found | Silent auto-creation | **FAIL LOUDLY** (it's a hook bug) |
-
----
-
-## The 7+ Failed Attempts
-
-- **Nov 4**: "Always store session data regardless of pre-existence." Complexity planted.
-- **Nov 11**: `INSERT OR IGNORE` recognized. But complexity documented, not removed.
-- **Nov 21**: Duplicate observations bug. Fixed. Then broken again by endless mode.
-- **Dec 5**: "6 hours of work delivered zero value." User requests self-audit.
-- **Dec 20**: "Phase 2: Eliminated Race Conditions" — felt like progress. Complexity remained.
-- **Dec 24**: Finally, forced deletion.
-
-The user stated "hooks provide session IDs, no extra management needed" **seven times** across months. Claude didn't listen.
-
----
-
-## The Fix
-
-### Deleted (984 lines):
-- 11 `SessionStore` methods: `incrementPromptCounter`, `getPromptCounter`, `setWorkerPort`, `getWorkerPort`, `markSessionCompleted`, `markSessionFailed`, `reactivateSession`, `findActiveSDKSession`, `findAnySDKSession`, `updateSDKSessionId`
-- Auto-create logic from `storeObservation` and `storeSummary`
-- The entire cleanup hook (was aborting SDK agent and causing data loss)
-- 117 lines from `worker-utils.ts`
-
-### What remains (~10 lines):
-```javascript
-createSDKSession(sessionId) {
-  db.run('INSERT OR IGNORE INTO sdk_sessions (...) VALUES (...)');
-  return db.query('SELECT id FROM sdk_sessions WHERE ...').get(sessionId);
-}
-```
-
-**That's it.**

-## Behavior Change
-
-- **Before:** Missing session? Auto-create silently. Bug hidden.
-- **After:** Missing session? Storage fails. Bug visible immediately.

-Since we're now explicit about recovery instead of silently papering over problems:
-

+### Mode & Language Configuration
+
+Claude-Mem supports multiple workflow modes and languages via the `CLAUDE_MEM_MODE` setting.
+
+This option controls both:
+- The workflow behavior (e.g. code, chill, investigation)
+- The language used in generated observations
+
+#### How to Configure
+
+Edit your settings file at `~/.claude-mem/settings.json`:
+
+```json
+{
+  "CLAUDE_MEM_MODE": "code--zh"
+}
+```
+
+Modes are defined in `plugin/modes/`. To see all available modes locally:
+
+```bash
+ls ~/.claude/plugins/marketplaces/thedotmack/plugin/modes/
+```
+
+#### Available Modes
+
+| Mode | Description |
+|------------|-------------------------|
+| `code` | Default English mode |
+| `code--zh` | Simplified Chinese mode |
+| `code--ja` | Japanese mode |
+
+Language-specific modes follow the pattern `code--[lang]` where `[lang]` is the ISO 639-1 language code (e.g., `zh` for Chinese, `ja` for Japanese, `es` for Spanish).
+
+> Note: `code--zh` (Simplified Chinese) is already built-in — no additional installation or plugin update is required.
+
+#### After Changing Mode
+
+Restart Claude Code to apply the new mode configuration.

-# Claude-Mem Public Documentation
-
-## What This Folder Is
-
-This `docs/public/` folder contains the **Mintlify documentation site** - the official user-facing documentation for claude-mem. It's a structured documentation platform with a specific file format and organization.
-
-## Folder Structure
-
-```
-docs/
-├── public/          ← You are here (Mintlify MDX files)
-│   ├── *.mdx       - User-facing documentation pages
-│   ├── docs.json   - Mintlify configuration and navigation
-│   ├── architecture/ - Technical architecture docs
-│   ├── usage/      - User guides and workflows
-│   └── *.webp, *.gif - Assets (logos, screenshots)
-└── context/        ← Internal documentation (DO NOT put here)
-    └── *.md        - Planning docs, audits, references
-```
-
-## File Requirements
-
-### Mintlify Documentation Files (.mdx)
-All official documentation files must be:
-- Written in `.mdx` format (Markdown with JSX support)
-- Listed in `docs.json` navigation structure
-- Follow Mintlify's schema and conventions
-
-The documentation is organized into these sections:
-- **Get Started**: Introduction, installation, usage guides
-- **Best Practices**: Context engineering, progressive disclosure
-- **Configuration & Development**: Settings, dev workflow, troubleshooting
-- **Architecture**: System design, components, technical details
-
-### Configuration File
-`docs.json` defines:
-- Site metadata (name, description, theme)
-- Navigation structure
-- Branding (logos, colors)
-- Footer links and social media
-
-## What Does NOT Belong Here
-
-**Planning documents, design docs, and reference materials go in `/docs/context/` instead:**
-
-Files that belong in `/docs/context/` (NOT here):
-- Planning documents (`*-plan.md`, `*-outline.md`)
-- Implementation analysis (`*-audit.md`, `*-code-reference.md`)
-- Error tracking (`typescript-errors.md`)
-- Internal design documents
-- PR review responses
-- Reference materials (like `agent-sdk-ref.md`)
-- Work-in-progress documentation

-## How to Add Official Documentation
-
-1. Create a new `.mdx` file in the appropriate subdirectory
-2. Add the file path to `docs.json` navigation
-3. Use Mintlify's frontmatter and components
-4. Follow the existing documentation style
-5. Test locally: `npx mintlify dev`
-
-## Development Workflow
-
-**For contributors working on claude-mem:**
-- Read `/CLAUDE.md` in the project root for development instructions
-- Place planning/design docs in `/docs/context/`
-- Only add user-facing documentation to `/docs/public/`
-- Test documentation locally with Mintlify CLI before committing
-
-## Testing Documentation
-
-```bash
-# Validate docs structure
-npx mintlify validate
-
-# Check for broken links
-npx mintlify broken-links
-
-# Run local dev server
-npx mintlify dev
-```
-
-## Summary
-
-**Simple Rule**:
-- `/docs/public/` = Official user documentation (Mintlify .mdx files) ← YOU ARE HERE
-- `/docs/context/` = Internal docs, plans, references, audits

+---
+
+# Knowledge Agents
+
+Knowledge agents let you compile a slice of your claude-mem observation history into a **queryable "brain"** that answers questions conversationally. Instead of getting raw search results back, you get synthesized, grounded answers drawn from your actual project history -- decisions, discoveries, bugfixes, and features.
+
+## Quick Start
+
+Three ways to use knowledge agents, from simplest to most powerful.
+
+### 1. Create a Knowledge Agent
+
+Use the `/knowledge-agent` skill or the MCP tools directly:
+
+```
+build_corpus name="hooks-expertise" query="hooks architecture" project="claude-mem" limit=200
+```
+
+This searches your observation history, collects matching records, and saves them as a corpus file. Then prime it — this loads the corpus into a Claude session's context window:
+
+```
+prime_corpus name="hooks-expertise"
+```
+
+Your knowledge agent is ready. The returned `session_id` **is** the agent — a Claude session with your history baked in.
+
+### 2. Ask a Single Question
+
+Once primed, ask any question and get a grounded answer:
+
+```
+query_corpus name="hooks-expertise" question="What are the 5 lifecycle hooks and when does each fire?"
+```
+
+The agent answers grounded in its corpus — responses are drawn from your actual project history, reducing hallucination and guessing. Each follow-up question builds on the prior conversation:
+
+```
+query_corpus name="hooks-expertise" question="Which hook handles context injection?"
+```
+
+### 3. Start a Fresh Conversation
+
+If the conversation drifts, or you want to ask an unrelated question against the same corpus, reprime to start clean:
+
+```
+reprime_corpus name="hooks-expertise"
+```
+
+This creates a **new session** with the full corpus reloaded — like opening a fresh chat with the same "brain." All prior Q&A context is cleared, but the corpus knowledge remains. Use this when:
+
+- The conversation went off-track and you want a clean slate
+- You're switching topics within the same corpus
+- You want to ask a question without prior answers biasing the response
+
+### Keeping It Current
+
+When new observations are added to your project, rebuild the corpus to pull in the latest, then reprime:
+
+```
+rebuild_corpus name="hooks-expertise"
+reprime_corpus name="hooks-expertise"
+```
+
+Rebuild re-runs the original search filters. Reprime loads the refreshed data into a new session.
+
+---
+
+## The Workflow: Build, Prime, Query
+
+```
+BUILD  ──>  PRIME  ──>  QUERY
+```
+
+### 1. Build a Corpus
+
+A corpus is a filtered collection of observations saved as a JSON file. Use search filters to select exactly the slice of history you want.
+
+```bash
+curl -X POST http://localhost:37777/api/corpus \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "hooks-expertise",
+    "query": "hooks architecture",
+    "project": "claude-mem",
+    "types": ["decision", "discovery"],
+    "limit": 200
+  }'
+```
+
+Under the hood, `CorpusBuilder` searches your observations, hydrates full records, parses structured fields (facts, concepts, files), calculates stats, and writes everything to `~/.claude-mem/corpora/hooks-expertise.corpus.json`.
+
+### 2. Prime the Knowledge Agent
+
+Priming loads the entire corpus into a Claude session's context window.
+
+```bash
+curl -X POST http://localhost:37777/api/corpus/hooks-expertise/prime
+```
+
+The agent renders all observations into full-detail text and feeds them to the Claude Agent SDK. Claude reads the corpus and acknowledges the themes. The returned `session_id` **is** the knowledge agent -- a Claude session with your history baked in.
+
+### 3. Query
+
+Resume the primed session and ask questions.
+
+```bash
+curl -X POST http://localhost:37777/api/corpus/hooks-expertise/query \
+  -H "Content-Type: application/json" \
+  -d '{ "question": "What are the 5 lifecycle hooks?" }'
+```
+
+Each follow-up question adds to the conversation naturally. If the session expires, the agent auto-reprimes from the corpus file and retries.
+
+---
+
+## Filter Options
+
+Use these parameters when building a corpus to control which observations are included:
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `name` | string | Name for the corpus (used in all subsequent API calls) |
+| `project` | string | Filter by project name |
+| `types` | string[] | Filter by observation type (bugfix, feature, decision, discovery, refactor, change) |
+| `concepts` | string[] | Filter by tagged concepts |
+| `files` | string[] | Filter by files read or modified |
+| `query` | string | Full-text search query |
+| `dateStart` | string | Start date filter (YYYY-MM-DD) |
+| `dateEnd` | string | End date filter (YYYY-MM-DD) |
+| `limit` | number | Maximum observations to include |
+
+---
+

+                                    (~/.claude-mem/corpora/)
+```
+
+**Key insight:** The Agent SDK's `resume` option lets you prime a session once (upload the corpus), save the `session_id`, and resume it for every future question. The corpus stays in context permanently -- no re-uploading, no prompt caching tricks. The 1M token context window makes this viable: 2,000 observations at ~300 tokens each fits comfortably.
+
+---
+
+## When to Use `/knowledge-agent` vs `/mem-search`
+
+| | `/mem-search` | `/knowledge-agent` |
+|---|---|---|
+| **Returns** | Raw observation records | Synthesized conversational answers |
+| **Best for** | Finding specific observations, IDs, timelines | Asking questions about patterns, decisions, architecture |
+| **Token model** | Pay-per-query (3-layer progressive disclosure) | Pay-once at prime time, then cheap follow-ups |
+| **Interaction** | Search, filter, fetch | Ask questions in natural language |
+| **Data freshness** | Always current (queries database live) | Snapshot at build time (rebuild to refresh) |
+| **Setup** | None -- works immediately | Build + prime required before first query |
+
+**Rule of thumb:** Use `/mem-search` when you need to find something specific. Use `/knowledge-agent` when you want to understand something broadly.
+
+---
+
+## API Reference
+
+| Method | Path | Description |
+|--------|------|-------------|
+| POST | `/api/corpus` | Build a new corpus from filters |
+| GET | `/api/corpus` | List all corpora with stats |
+| GET | `/api/corpus/:name` | Get corpus metadata |
+| DELETE | `/api/corpus/:name` | Delete a corpus |
+| POST | `/api/corpus/:name/rebuild` | Rebuild from stored filters |
+| POST | `/api/corpus/:name/prime` | Create AI session with corpus loaded |
+| POST | `/api/corpus/:name/query` | Ask the knowledge agent a question |
+| POST | `/api/corpus/:name/reprime` | Fresh session (wipe prior Q&A) |
+
+---
+
+## Edge Cases
+
+- **Session expiry**: If `resume` fails, the agent auto-reprimes from the corpus file and retries
+- **SDK process exit**: If the Claude process exits after yielding all messages, the agent treats it as success when the session_id or answer was already captured
+- **Empty corpus**: A corpus with 0 observations is valid (just empty)
+- **Model from settings**: Reads `CLAUDE_MEM_MODEL` from user settings -- no hardcoded model IDs

+Build and query AI-powered knowledge bases from claude-mem observations.
+
+## What Are Knowledge Agents?
+
+Knowledge agents are filtered corpora of observations compiled into a conversational AI session. Build a corpus from your observation history, prime it (loads the knowledge into an AI session), then ask it questions conversationally.
+
+Think of them as custom "brains": "everything about hooks", "all decisions from the last month", "all bugfixes for the worker service".
+
+## Workflow
+
+### Step 1: Build a corpus
+
+```text
+build_corpus name="hooks-expertise" description="Everything about the hooks lifecycle" project="claude-mem" concepts="hooks" limit=500
+```
+
+Filter options:
+- `project` — filter by project name
+- `types` — comma-separated: decision, bugfix, feature, refactor, discovery, change
+- `concepts` — comma-separated concept tags
+- `files` — comma-separated file paths (prefix match)
+- `query` — semantic search query
+- `dateStart` / `dateEnd` — ISO date range
+- `limit` — max observations (default 500)

+### Step 2: Prime the corpus
+
+```text
+prime_corpus name="hooks-expertise"
+```
+
+This creates an AI session loaded with all the corpus knowledge. Takes a moment for large corpora.
+
+### Step 3: Query
+
+```text
+query_corpus name="hooks-expertise" question="What are the 5 lifecycle hooks and when does each fire?"
+```
+
+The knowledge agent answers from its corpus. Follow-up questions maintain context.
+
+### Step 4: List corpora
+
+```text
+list_corpora
+```
+
+Shows all corpora with stats and priming status.
+
+## Tips
+
+- **Focused corpora work best** — "hooks architecture" beats "everything ever"
+- **Prime once, query many times** — the session persists across queries
+- **Reprime for fresh context** — if the conversation drifts, reprime to reset
+- **Rebuild to update** — when new observations are added, rebuild then reprime
+
+## Maintenance
+
+### Rebuild a corpus (refresh with new observations)
+
+```text
+rebuild_corpus name="hooks-expertise"
+```
+
+After rebuilding, reprime to load the updated knowledge:
+
+### Reprime (fresh session)
+
+```text
+reprime_corpus name="hooks-expertise"
+```
+
+Clears prior Q&A context and reloads the corpus into a new session.

-## Smart-Explore Language Support
+## Knowledge Agents
 
-Smart-explore tools (`smart_search`, `smart_outline`, `smart_unfold`) use tree-sitter AST parsing. The following languages are supported out of the box.
-
-### 24 Bundled Languages
-
-JS, TS, Python, Go, Rust, Ruby, Java, C, C++, Kotlin, Swift, PHP, Elixir, Lua, Scala, Bash, Haskell, Zig, CSS, SCSS, TOML, YAML, SQL, Markdown
-
-### Markdown Special Support
-
-Markdown files get structure-aware parsing beyond generic tree-sitter:
-
-- **Heading hierarchy** -- `#`/`##`/`###` headings are extracted as nested symbols (sections contain subsections)
-- **Code block detection** -- fenced code blocks are surfaced as `code` symbols with language annotation
-- **Section-aware unfold** -- `smart_unfold` on a heading returns the full section content (heading through all subsections until the next heading of equal or higher level)
-
-### User-Installable Grammars via `.claude-mem.json`
-
-Add custom tree-sitter grammars for languages not in the bundled set. Place `.claude-mem.json` in the project root:
-
-```json
-{
-  "grammars": {
-    "gleam": {
-      "package": "tree-sitter-gleam",
-      "extensions": [".gleam"]
-    },
-    "protobuf": {
-      "package": "tree-sitter-proto",
-      "extensions": [".proto"],
-      "query": ".claude-mem/queries/proto.scm"
-    }
-  }
-}
-```
-
-**Fields:**
-
-- `package` (string, required) -- npm package name for the tree-sitter grammar
-- `extensions` (array of strings, required) -- file extensions to associate with this language
-- `query` (string, optional) -- path to a custom `.scm` query file for symbol extraction. If omitted, a generic query is used.
-
-**Rules:**
-
-- User grammars do NOT override bundled languages. If a language is already bundled, the entry is ignored.
-- The npm package must be installed in the project (`npm install tree-sitter-gleam`).
-- Config is cached per project root. Changes to `.claude-mem.json` take effect on next worker restart.

 **4-8x savings** on file understanding (outline + unfold vs Read). **11-18x savings** on codebase exploration vs Explore agent. The narrower the query, the wider the gap — a 27-line function costs 55x less to read via unfold than via an Explore agent, because the agent still reads the entire file.
+
+## Language Support
+
+Smart-explore uses **tree-sitter AST parsing** for structural analysis. Unsupported file types fall back to text-based search.
+
+### Bundled Languages
+
+| Language | Extensions |
+|----------|-----------|
+| JavaScript | `.js`, `.mjs`, `.cjs` |
+| TypeScript | `.ts` |
+| TSX / JSX | `.tsx`, `.jsx` |
+| Python | `.py`, `.pyw` |
+| Go | `.go` |
+| Rust | `.rs` |
+| Ruby | `.rb` |
+| Java | `.java` |
+| C | `.c`, `.h` |
+| C++ | `.cpp`, `.cc`, `.cxx`, `.hpp`, `.hh` |
+
+Files with unrecognized extensions are parsed as plain text — `smart_search` still works (grep-style), but `smart_outline` and `smart_unfold` will not extract structured symbols.
+
+### Custom Grammars (`.claude-mem.json`)
+
+You can register additional tree-sitter grammars for file types not in the bundled list. Create or update `.claude-mem.json` in your project root:
+
+```json
+{
+  "grammars": {
+    ".sol": "tree-sitter-solidity",
+    ".graphql": "tree-sitter-graphql"
+  }
+}
+```
+
+Each key is a file extension; each value is the npm package name of the tree-sitter grammar. The grammar must be installed locally (`npm install tree-sitter-solidity`). Once registered, `smart_outline` and `smart_unfold` will parse those extensions structurally instead of falling back to plain text.
+
+### Markdown Special Support
+
+Markdown files (`.md`, `.mdx`) receive special handling beyond the generic plain-text fallback:
+
+- **`smart_outline`** — extracts headings (`#`, `##`, `###`) as the symbol tree. Use it to navigate long documents without reading the full file.
+- **`smart_search`** — searches within code fences as well as prose, so queries for function names inside ` ```ts ``` ` blocks work as expected.
+- **`smart_unfold`** — expands heading sections rather than function bodies; each section up to the next same-level heading is returned as a chunk.
+- **Frontmatter** — YAML frontmatter (lines between leading `---` delimiters) is included in `smart_outline` output under a synthetic `frontmatter` symbol so metadata like `title:` and `description:` is visible without reading the whole file.

-# Error Handling Anti-Pattern Rules
-
-This folder contains `detect-error-handling-antipatterns.ts` - run it before committing any error handling changes.
-
-## The Try-Catch Problem That Cost 10 Hours
-
-A single overly-broad try-catch block wasted 10 hours of debugging time by silently swallowing errors.
-**This pattern is BANNED.**
-
-## BEFORE You Write Any Try-Catch
-
-**RUN THIS TEST FIRST:**
-```bash
-bun run scripts/anti-pattern-test/detect-error-handling-antipatterns.ts
-```
-
-**You MUST answer these 5 questions to the user BEFORE writing try-catch:**
-
-1. **What SPECIFIC error am I catching?** (Name the error type: `FileNotFoundError`, `NetworkTimeout`, `ValidationError`)
-2. **Show documentation proving this error can occur** (Link to docs or show me the source code)
-3. **Why can't this error be prevented?** (If it can be prevented, prevent it instead)
-4. **What will the catch block DO?** (Must include logging + either rethrow OR explicit fallback)
-5. **Why shouldn't this error propagate?** (Justify swallowing it rather than letting caller handle)
-
-**If you cannot answer ALL 5 questions with specifics, DO NOT write the try-catch.**
-
-## FORBIDDEN PATTERNS (Zero Tolerance)
-
-### CRITICAL - Never Allowed
-
-```typescript
-// FORBIDDEN: Empty catch
-try {
-  doSomething();
-} catch {}
-
-// FORBIDDEN: Catch without logging
-try {
-  doSomething();
-} catch (error) {
-  return null;  // Silent failure!
-}
-
-// FORBIDDEN: Large try blocks (>10 lines)
-try {
-  // 50 lines of code
-  // Multiple operations
-  // Different failure modes
-} catch (error) {
-  logger.error('Something failed');  // Which thing?!
-}
-
-// FORBIDDEN: Promise empty catch
-promise.catch(() => {});  // Error disappears into void
-
-// FORBIDDEN: Try-catch to fix TypeScript errors
-try {
-  // @ts-ignore
-  const value = response.propertyThatDoesntExist;
-} catch {}
-```
-
-### ALLOWED Patterns
-
-```typescript
-// GOOD: Specific, logged, explicit handling
-try {
-  await fetch(url);
-} catch (error) {
-  if (error instanceof NetworkError) {
-    logger.warn('SYNC', 'Network request failed, will retry', { url }, error);
-    return null;  // Explicit: null means "fetch failed"
-  }
-  throw error;  // Unexpected errors propagate
-}
-
-// GOOD: Minimal scope, clear recovery
-try {
-  JSON.parse(data);
-} catch (error) {
-  logger.error('CONFIG', 'Corrupt settings file, using defaults', {}, error);
-  return DEFAULT_SETTINGS;
-}
-
-// GOOD: Fire-and-forget with logging
-backgroundTask()
-  .catch(error => logger.warn('BACKGROUND', 'Task failed', {}, error));
-
-// GOOD: Ignored anti-pattern for genuine hot paths only
-try {
-  checkIfProcessAlive(pid);
-} catch (error) {
-  // [ANTI-PATTERN IGNORED]: Tight loop checking 100s of PIDs during cleanup
-  return false;
-}
-```
-
-## Ignoring Anti-Patterns (Rare)
-
-**Only for genuine hot paths** where logging would cause performance problems:
-
-```typescript
-// [ANTI-PATTERN IGNORED]: Reason why logging is impossible
-```
-
-**Rules:**
-- **Hot paths only** - code in tight loops called 1000s of times
-- If you can add logging, ADD LOGGING - don't ignore
-- Valid examples:
-  - "Tight loop checking process exit status during cleanup"
-  - "Health check polling every 100ms"
-- Invalid examples:
-  - "Expected JSON parse failures" - Just add logger.debug
-  - "Common fallback path" - Just add logger.debug
-
-## The Meta-Rule
-
-**UNCERTAINTY TRIGGERS RESEARCH, NOT TRY-CATCH**
-
-When you're unsure if a property exists or a method signature is correct:
-1. **READ** the source code or documentation
-2. **VERIFY** with the Read tool
-3. **USE** TypeScript types to catch errors at compile time
-4. **WRITE** code you KNOW is correct
-
-Never use try-catch to paper over uncertainty. That wastes hours of debugging time later.
-
-## Critical Path Protection
-
-These files are **NEVER** allowed to have catch-and-continue:
-- `SDKAgent.ts` - Errors must propagate, not hide
-- `GeminiAgent.ts` - Must fail loud, not silent
-- `OpenRouterAgent.ts` - Must fail loud, not silent
-- `SessionStore.ts` - Database errors must propagate
-- `worker-service.ts` - Core service errors must be visible
-
-On critical paths, prefer **NO TRY-CATCH** and let errors propagate naturally.

+/**
+ * WorktreeAdoption - Stamp observations from merged worktrees into their parent project.
+ *
+ * Given a parent repo path, this engine:
+ *   1. Uses git to enumerate worktrees of the parent repo.
+ *   2. Classifies each worktree's branch as "merged" (in `git branch --merged HEAD`)
+ *      or manually overridden via `onlyBranch` (for squash-merge detection).
+ *   3. Stamps `merged_into_project` on `observations` and `session_summaries` rows
+ *      whose `project` matches the composite `parent/worktree` name.
+ *   4. Propagates the same metadata to Chroma so semantic search includes the
+ *      adopted rows under the parent project.
+ *
+ * `project` is never overwritten — it remains immutable provenance. The
+ * `merged_into_project` column is a virtual pointer that query layers OR into
+ * their WHERE predicates.
+ *
+ * DB lifecycle mirrors `runOneTimeCwdRemap` in ProcessManager.ts: we manage our
+ * own Database handle (open -> transaction -> close in finally) so this engine
+ * can be called on worker startup before `dbManager.initialize()` without
+ * contending on the shared handle.
