+# Phase 33 Plan 01: Persistent Memory Foundation Summary
+
+**File-backed assistant memory service with write-time credential sanitization and REST endpoints mounted in app.ts.**
+
+## Performance
+- **Duration:** 4 minutes
+- **Tasks:** 2 completed
+- **Files modified:** 6
+
+## Accomplishments
+- `sanitizeMemoryFact` scrubs OpenAI (sk-), GitHub PAT (ghp_), Google API (AIza), JWT-shaped tokens, and key=value credential patterns at write time
+- `assistantMemoryService` provides file-backed get/append/clear scoped per companyId at `data/assistant-memory/<companyId>.json`
+- 50-fact FIFO cap enforced in append()
+- REST routes at `/api/assistant-memory/:companyId` with assertBoard + assertCompanyAccess auth on all three verbs
+- 17 unit tests pass (10 sanitizer, 7 service)
+
+## Task Commits
+1. **Task 1 (RED): Failing tests** - `378d1c11`
+2. **Task 1 (GREEN): Memory sanitizer + service** - `fb3c1578`
+3. **Task 2: Routes + app.ts wiring** - `eba57c5c`
+
+## Files Created/Modified
+- `server/src/services/memory-sanitizer.ts` - `sanitizeMemoryFact` with CREDENTIAL_INLINE_RE and SENSITIVE_KEY_VALUE_RE
+- `server/src/services/assistant-memory.ts` - `assistantMemoryService()` with get/append/clear, resolveMemoryPath, 50-fact cap
+- `server/src/routes/assistant-memory.ts` - `assistantMemoryRoutes()` GET/PATCH/DELETE with auth guards
+- `server/src/app.ts` - Added import + `api.use(assistantMemoryRoutes())` mount
+- `server/src/__tests__/33-memory-sanitization.test.ts` - 10 sanitizer tests
+- `server/src/__tests__/33-assistant-memory.test.ts` - 7 service tests with os.tmpdir() isolation
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] GitHub PAT regex too strict**
+- **Found during:** Task 1 (TDD GREEN)
+- **Issue:** `ghp_[A-Za-z0-9]{36}` matched exactly 36 chars, leaving trailing chars unredacted (`[REDACTED]k`)
+- **Fix:** Changed to `{36,}` to match minimum 36 chars
+- **Files modified:** `server/src/services/memory-sanitizer.ts`
+- **Commit:** fb3c1578
+
+**2. [Rule 3 - Blocking] Zod not resolvable in worktree vitest context**
+- **Found during:** Task 1 (TDD GREEN)
+- **Issue:** Worktree's server `node_modules` has no zod symlink; vitest cannot resolve `zod` during test collection
+- **Fix:** Removed zod import from `assistant-memory.ts`, replaced schema validation with manual type guard
+- **Files modified:** `server/src/services/assistant-memory.ts`
+- **Commit:** fb3c1578
+
+## Known Stubs
+None — all data paths are fully wired.
+
+## Next Phase Readiness
+- `assistantMemoryService` ready for injection into chat route (`server/src/services/chat.ts`) in Plan 02
+- Routes already mounted; API is live on server start
