# Phase 22: Course Load Testing Verification Report

**Phase Goal:** Course learners can follow a hands-on load testing tutorial and understand where load testing fits in the broader testing curriculum
**Verified:** 2026-02-27
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| #  | Truth | Status | Evidence |
|----|-------|--------|----------|
| 1  | Ch 18-03 provides a hands-on tutorial using `cargo pmcp loadtest` that learners can follow step-by-step | VERIFIED | 952-line file with 11 major sections, step-numbered walkthrough ("Step 1: Start Your Server", "Step 2: Generate a Config", "Step 3: Run the Test"), multiple "Try this:" exercises, teaching voice throughout |
| 2  | Ch 18-03 covers TOML config authoring, `loadtest init` schema discovery, staged load profiles, and result interpretation | VERIFIED | All four topics present with dedicated sections: "Understanding the Config File" (TOML authoring from scratch), "Your First Load Test" (init schema discovery walkthrough), "Staged Load Profiles" (flat vs staged with ASCII diagrams), "Reading Your Results" (P50/P95/P99 explanation + terminal output annotation + HdrHistogram + coordinated omission) |
| 3  | Ch 18-03 includes a practical example of load testing a deployed MCP server with capacity planning guidance | VERIFIED | Dedicated "Load Testing a Deployed Server" section (line 710+) with 3 sub-sections: remote server considerations, staging walkthrough with config customization, capacity planning framework with VU-to-P99 decision table and 2x headroom rule |
| 4  | Ch 12 (Remote Testing) contains a brief load testing section cross-referencing Ch 18-03 for full hands-on content | VERIFIED | "Load Testing Your Deployed Servers" section at line 612, blockquote callout cross-reference at line 646 (`ch18-03-performance.md`), learning objective updated (line 13), Chapter Summary updated (item 6, line 657), Practice Ideas updated (item 5, line 679) |

**Score:** 4/4 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `pmcp-course/src/part7-observability/ch18-03-performance.md` | Complete hands-on load testing tutorial replacing stub; min 500 lines; contains "cargo pmcp loadtest" | VERIFIED | 952 lines; 11 major `##` sections; "cargo pmcp loadtest" appears 30+ times; teaching voice confirmed; no stubs or placeholders detected |
| `pmcp-course/src/part4-testing/ch12-remote-testing.md` | Load testing cross-reference section added; contains "Load Testing"; links to ch18-03-performance | VERIFIED | "Load Testing" appears 3 times (section header, summary, practice idea); `ch18-03-performance` link appears twice; all prior content preserved (52 matches for mcp-tester/Regression/CI/CD/smoke) |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `ch18-03-performance.md` | `pmcp-book/src/ch14-performance.md` | Cross-reference to book for full reference docs | WIRED | Two links present: line 43 (early intro) and line 918 (Quick Reference closing) — both reference `ch14-performance.md` |
| `ch12-remote-testing.md` | `ch18-03-performance.md` | Cross-reference link directing learners to full tutorial | WIRED | Line 646 blockquote callout with relative link `../part7-observability/ch18-03-performance.md`; line 657 Summary item also links |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| CRLT-01 | 22-01-PLAN.md | Ch 18-03 rewritten from stub with hands-on load testing tutorial | SATISFIED | File is 952 lines (was a one-line stub per PLAN); contains step-by-step instructions, Learning Objectives, "Try this" exercises, Practice Ideas |
| CRLT-02 | 22-01-PLAN.md | Ch 18-03 covers TOML config authoring, `loadtest init`, staged load profiles, result interpretation | SATISFIED | Verified all four sub-requirements: "Understanding the Config File" section (TOML authoring), "Step 2: Generate a Config" (init with schema discovery), "Staged Load Profiles" section with [[stage]] blocks, "Reading Your Results" section with percentile/HdrHistogram/coordinated omission teaching |
| CRLT-03 | 22-01-PLAN.md | Ch 18-03 includes practical deployed server example with capacity planning | SATISFIED | "Load Testing a Deployed Server" section (lines 710-851) with complete staging walkthrough and capacity planning decision framework with rules of thumb |
| CRLT-04 | 22-02-PLAN.md | Ch 12 updated with brief load testing section cross-referencing Ch 18-03 | SATISFIED | Section added at line 612; blockquote callout at line 646; learning objective, summary, and practice ideas all updated |

No orphaned requirements: REQUIREMENTS.md maps CRLT-01 through CRLT-04 exclusively to Phase 22, all four are accounted for and satisfied.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| — | — | — | — | No anti-patterns detected |

Scan results:
- No TODO/FIXME/XXX/HACK/PLACEHOLDER comments in either file
- No stub patterns ("coming soon", "will be here") in either file
- No empty content blocks or placeholder sections detected

### Human Verification Required

None. Both deliverables are documentation files (Markdown). All success criteria are verifiable programmatically via content inspection.

### Gaps Summary

No gaps. All four observable truths are verified. Both artifacts pass all three levels (exists, substantive, wired). Both key links are confirmed present in the actual file content, not assumed from summaries. All four phase requirements are satisfied with direct evidence from the codebase.
