# Phase 8: Quality Polish and Test Coverage Verification Report

**Phase Goal:** Close all tech debt and integration findings from the v1.1 milestone audit — accurate SchemaMismatch diagnostics, complete PauseReason coverage, zero clippy warnings, and full E2E continuation test coverage
**Verified:** 2026-02-23T20:30:00Z
**Status:** passed
**Re-verification:** Yes — gap resolved (ROADMAP checkboxes and progress table updated)

## Goal Achievement

### Observable Truths (from ROADMAP.md Success Criteria)

| #  | Truth                                                                                                             | Status     | Evidence                                                                                                              |
|----|-------------------------------------------------------------------------------------------------------------------|------------|-----------------------------------------------------------------------------------------------------------------------|
| 1  | `PauseReason::SchemaMismatch.missing_fields` contains actual missing field names (not `["unknown"]`)             | VERIFIED | `task_prompt_handler.rs:806` uses `missing.clone()` from `Vec<String>` return; no hardcoded `["unknown"]` in SchemaMismatch context |
| 2  | All execution break paths produce a `PauseReason` (no silent breaks)                                             | VERIFIED | Zero `Err(_) => break` patterns remain; both paths at lines 767-779 and 783-798 set PauseReason + `tracing::warn!`  |
| 3  | `cargo clippy --package pmcp-tasks -- -D warnings` passes with zero warnings                                     | VERIFIED | Clippy exits cleanly: `Finished dev profile` with no warnings (verified live run)                                    |
| 4  | Property test `fresh_task_record_is_not_expired` passes                                                          | VERIFIED | Test passes in `tests/property_tests.rs`; TTL range constrained to 30 days (2_592_000_000ms); `i64::try_from` in `record.rs` |
| 5  | Integration test exercises E2E continuation with succeeding tool through `ServerCore::handle_request` and verifies store update | VERIFIED | `test_full_lifecycle_happy_path` Stage 2 uses `ConditionalFetchDataTool` at `handle_request(RequestId::from(2i64)`, verifies `_workflow.result.fetch` and `_workflow.progress` in store |

**Score:** 5/5 success criteria technically verified in code

### Milestone Audit Item Closure

| Item              | Source                    | Status   | Evidence                                                                                                   |
|-------------------|---------------------------|----------|------------------------------------------------------------------------------------------------------------|
| FINDING-01        | SchemaMismatch hardcoded  | CLOSED   | `params_satisfy_tool_schema` returns `Vec<String>`; `missing.clone()` used in `PauseReason::SchemaMismatch` |
| FINDING-02        | E2E continuation gap      | CLOSED   | `ConditionalFetchDataTool` + Stage 2 in `test_full_lifecycle_happy_path` closes the coverage gap          |
| Tech Debt: Phase 4 clippy | `router.rs:554`   | CLOSED   | `assert!(!record.variables.contains_key(...))` replaces `assert!(get().is_none())`                       |
| Tech Debt: Phase 5 silent break 1 | `line 574` | CLOSED   | Routes through `classify_resolution_failure` + `tracing::warn!`                                           |
| Tech Debt: Phase 5 silent break 2 | `line 578` | CLOSED   | Sets `PauseReason::UnresolvableParams` + `tracing::warn!`                                                 |
| Tech Debt: Phase 6 proptest TTL overflow | `property_tests.rs` | CLOSED | TTL range capped at 2_592_000_000ms; production uses `i64::try_from(ms).ok()?`; regression file deleted  |
| Tech Debt: Phase 7 Stage 2 commented out | `workflow_integration.rs` | CLOSED | Stage 2 implemented and passing                                                                            |

### Requirements Coverage

Phase 8 has no assigned requirement IDs (quality polish only). Closure of audit items is the contract.

All 7 audit items (FINDING-01, FINDING-02, 5 tech debt items) are closed in the codebase.

### Anti-Patterns Found

| File                                                    | Line | Pattern                                   | Severity | Impact                             |
|---------------------------------------------------------|------|-------------------------------------------|----------|------------------------------------|
No anti-patterns found. No TODO/FIXME/placeholder comments in modified files. No stub implementations. No silent breaks remain.

### Human Verification Required

None required. All success criteria are directly verifiable via compilation, test execution, and source inspection.

## Gaps Summary

No gaps. All 5 success criteria verified in code. ROADMAP.md updated with plan checkboxes and progress table.
