### Requirements Coverage

| Requirement | Source Plan | Description                                                                                                    | Status    | Evidence                                                             |

All 4 requirements SATISFIED. No orphaned requirements.

### Anti-Patterns Found

| File                                       | Line | Pattern     | Severity | Impact |
|--------------------------------------------|------|-------------|----------|--------|
| `pmcp-book/src/ch14-performance.md`        | —    | None found  | —        | —      |
| `pmcp-book/src/ch15-testing.md`            | —    | None found  | —        | —      |

No TODO/FIXME/placeholder comments found in either artifact. No stub implementations detected.

### Human Verification Required

None — all automated checks passed with clear quantitative evidence.

Optional quality check (not blocking):

#### 1. mdbook Build

**Test:** Run `mdbook build pmcp-book` from the workspace root.
**Expected:** Build succeeds with no broken link warnings referencing ch14-performance.md or ch15-testing.md.
**Why human:** Requires mdbook installation and full workspace build.

### Gaps Summary

No gaps found. All must-haves verified:

- Ch 14 (961 lines) comprehensively replaces the 12-line stub with full load testing documentation
- All key CLI flags, TOML config fields, metric names, and report schema fields are present (derived from actual Rust source)
- Ch 15 cross-references Ch 14 with 3 link occurrences and "Load Testing" appears 4 times in the chapter
- All 4 BKLT requirements are satisfied with quantitative evidence
- No anti-patterns (stubs, TODOs, empty sections) found
