- [Phase 31-puter.js-zero-config-cloud]: Plan 04 is verification-only — auto-approved under workflow.auto_advance=true; full UAT deferred to manual QA session
- [Phase 32-multi-step-onboarding-wizard]: createWorkspace() helper extracted so both handleSubmit and handleStartChat share workspace creation without duplication
- [Phase 32-multi-step-onboarding-wizard]: Step 4 form submit removed — replaced with button advancing to step 5; actual workspace creation deferred to summary CTA
- [Phase 33]: Removed zod dependency from assistant-memory.ts — replaced with manual type guard due to worktree node_modules not having zod symlink
- [Phase 33]: GitHub PAT regex changed from {36} to {36,} to handle tokens longer than the minimum expected length

# 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
