**Orphan check:** 0 orphaned requirements. All 19 IDs in traceability table have verification entries.

## Phase Verification Summary

| Phase | Status | Score | Gaps |
|-------|--------|-------|------|
| 4. Foundation Types and Contracts | passed | 8/8 | Doc gaps resolved (FNDX-02 ROADMAP/REQ updated) |
| 5. Partial Execution Engine | passed | 10/10 | Doc gap resolved (EXEC-04 reinterpretation noted) |
| 6. Structured Handoff and Client Continuation | passed | 13/13 | None |
| 7. Integration and End-to-End Validation | passed | 9/9 | None |
| 8. Quality Polish and Test Coverage | passed | 5/5 | None (closed all prior audit items) |

## Cross-Phase Integration

**Exports wired:** 14/14 — every Phase 4-8 export consumed by at least one downstream phase
**Orphaned exports:** 0
**API routes covered:** 5/5 task routes have callers in ServerCore
**Auth protection:** All task routes and continuation intercept resolve owner

### E2E Flow Status

| Flow | Status | Notes |
|------|--------|-------|
| Workflow invocation → task creation → handoff | Complete | 8-step path verified end-to-end |
| Client continuation → step recording | Complete | E2E test with `ConditionalFetchDataTool` in `test_full_lifecycle_happy_path` Stage 2 |
| Client polls tasks/result | Complete | Both not-ready error and post-completion success verified |
| Cancel-with-result → Completed transition | Complete | Direct store inspection confirms status |
| Backward compatibility (non-task workflow) | Complete | Both single and dual-workflow scenarios tested |

### Integration Findings

None. All findings from the previous audit (2026-02-23T17:30:00Z) have been closed by Phase 8.

## Previous Audit Finding Closure (Phase 8)

| Finding | Original Issue | Closed By | Evidence |
|---------|---------------|-----------|----------|
| FINDING-01 | `SchemaMismatch.missing_fields` hardcoded to `["unknown"]` | 08-01-PLAN | `params_satisfy_tool_schema` returns `Vec<String>`; `missing.clone()` used in PauseReason |
| FINDING-02 | E2E continuation with succeeding tool not tested | 08-02-PLAN | `ConditionalFetchDataTool` + Stage 2 in `test_full_lifecycle_happy_path` |
| Tech Debt: Phase 4 clippy | `router.rs:554` unnecessary_get_then_check | 08-02-PLAN | `contains_key` assertion replaces `get().is_none()` |
| Tech Debt: Phase 5 silent break 1 | `resolve_tool_parameters` failure with no PauseReason | 08-01-PLAN | Routes through `classify_resolution_failure` + `tracing::warn!` |
| Tech Debt: Phase 5 silent break 2 | `params_satisfy_tool_schema` Err with no PauseReason | 08-01-PLAN | Sets `PauseReason::UnresolvableParams` + `tracing::warn!` |
| Tech Debt: Phase 6 proptest | TTL overflow in `fresh_task_record_is_not_expired` | 08-02-PLAN | `i64::try_from(ms).ok()?` in production; 30-day ceiling in proptest |
| Tech Debt: Phase 7 Stage 2 | Continuation call commented out | 08-02-PLAN | Stage 2 implemented and passing with store verification |

**Total:** 7/7 items closed. Zero remaining tech debt.
