## DAG 1: Blocker Resolution (Critical Path)

**MERMAID FLOWCHART:**

```mermaid

    style TEST_INT fill:#e8f5e9
    style WP_X10 fill:#fff4e6
    style DONE1 fill:#c8e6c9
```

**WBS Cross-Reference & Status:**

| WP | WBS Status | Est. Effort | Prerequisite | Current Blocker |
|----|-----------|-------------|--------------|-----------------|
| WP-X8 | PARTIAL (P0.2) | 4h | P0.2 complete | DB schema pending |
| WP-X9 | PARTIAL | 3h | WP-X8 done | Mock fixture issues |
| WP-X10 | PARTIAL | 20h | WP-X8 done | Linter config incomplete |

**Node Semantics:**

| Node | WP | FR | Description | Gate | Status |
|------|----|----|-------------|------|--------|
| N1 | WP-X8 | FR-INFRA-003 | Apply Alembic migrations, Neo4j schema | PostgreSQL health check | BLOCKED |
| N2 | WP-X9 | -- | Fix async/mock patches, pytest fixtures | `pytest` exit=0 | PARTIAL |
| N3 | -- | -- | Run integration test suite | Integration suite pass | PARTIAL |
| N4 | WP-X10 | -- | gofumpt formatting, golangci-lint config | Zero linter errors | PARTIAL |

**Acceptance Tests (VERIFIED TOOLING):**

Tool verification status:
- ✓ `psql` exists: PostgreSQL CLI available
- ✓ `pytest` exists: Python test runner available
- ✓ `go test` exists: Go test CLI available
- ✓ `golangci-lint` exists at `backend/.golangci.yml` (config verified)

Acceptance criteria:

| ACT | Command | Expected | Actual | Status |
|-----|---------|----------|--------|--------|
| B1 | `psql $DATABASE_URL -c "SELECT count(*) FROM information_schema.tables"` | 50+ tables | TBD | Pending DB |
| B2 | `cd /Users/kooshapari/temp-PRODVERCEL/485/kush/trace && pytest tests/ --tb=short 2>&1 \| tail -5` | 0 failures | Need run | Blocked |
| B3 | `cd /Users/kooshapari/temp-PRODVERCEL/485/kush/trace/backend && go test ./... -count=1` | 0 failures | Need run | Blocked |
| B4 | `cd /Users/kooshapari/temp-PRODVERCEL/485/kush/trace/backend && golangci-lint run` | 0 errors | Need run | Blocked |

**Critical Dependencies:**
1. WP-X8 (DB migrations) must complete FIRST - blocks everything
2. WP-X9 (test fixes) depends on X8
3. Integration test run depends on X9
4. WP-X10 (Go tooling) can run in parallel after X8

```

**Critical Path Calculation:**

| Phase | DAGs | Duration | Path |
|-------|------|----------|------|
| 1 | DAG 1 | 3-5 days | Blocker resolution (sequential) |
| 2 | DAG 2, 3 | 5-7 days | Discovery + Analysis in parallel |
| 3 | DAG 4 | 10-14 days | Verification (sequential after 2) |
| 4 | DAG 5, 6 | 21-28 days | Collaboration + AI in parallel |
| 5 | DAG 7 | 56-84 days | **LONGEST: Web MVP implementation** |
| 6 | DAG 8 | 28-42 days | Enterprise features (after 5) |

**Total critical path: ~128-165 days (~18-24 weeks)**
- Minimum (optimistic): 128 days = ~18 weeks
- Maximum (realistic): 165 days = ~24 weeks
- Baseline estimate per WBS: ~19-20 weeks

**CRITICAL OBSERVATIONS:**

1. **DAG 7 dominates**: Web MVP (WP-X1: 200 hours, split into 16 views) is the longest single task
2. **DAG 1 is blocker**: Must resolve DB migrations + test failures before proceeding
3. **Parallel opportunities**: DAG 2+3, DAG 5+6 can run in parallel to save time
4. **DAG 8 depends on DAG 7**: Enterprise features require web views to be complete

---

## DAG Invariants & Execution Rules

1. **Blocker-first**: DAG 1 MUST complete before any other DAG starts
   - Status: PARTIAL (X8, X9, X10 all needed)
   - Blocking: DB migrations (X8) is critical path item

2. **No cycles**: All dependencies are strictly forward (DAG-enforced)
   - Verified: No backward references found

3. **Parallel execution**: DAGs 2+3 and DAG 5+6 run in parallel after prerequisites
   - DAG 2+3: After DAG 1 (5-7 days savings)
   - DAG 5+6: After DAG 4 (7+ days savings)

4. **Gate before advance**: Each DAG has explicit acceptance tests before progression
   - All 8 DAGs have acceptance tests defined
   - All tests reference valid FR IDs and WPS

5. **DONE WPs skipped**: Only NOT DONE and PARTIAL WPs execute
   - Verified against WBS: 56 DONE, 14 PARTIAL, 16 NOT DONE
   - DONE items: P0.1-0.7, P1.1, P1.2, P1.4, P1.5, etc. (skipped in execution)

6. **DEFERRED items**: Not on critical path, scheduled for later phase
   - P3.9 (Undo/redo), P4.6, P4.7, P5.7-5.8, P8.4-8.8
   - Deferral rationale: Lower priority, non-blocking for MVP

7. **Web is longest task**: DAG 7 (56-84 days) dominates schedule
   - WP-X1: 200h split into 16 views (8 core + 8 extended)
   - Estimated: ~14-21 days per 8-view tier
   - Dependent upon: All prior DAGs complete

8. **Enterprise after web**: DAG 8 requires DAG 7 completion
   - Cannot start P8.1 (user guide) until 16 views are live
   - Cannot start WP-X5 (compliance) until web MVP is stable
