# Phase 24 Plan 01: Ch18 Quiz and Loadtest Exercise Summary

**10-question ch18 operations quiz covering load testing CLI, percentiles, coordinated omission, and capacity planning, plus a 6-phase AI-guided exercise TOML for hands-on loadtest practice**

## Performance

- **Duration:** 2 min
- **Started:** 2026-02-28T04:51:46Z
- **Completed:** 2026-02-28T04:54:09Z
- **Tasks:** 2
- **Files created:** 2

## Accomplishments
- Created ch18-operations.toml quiz with 10 questions (8 MultipleChoice, 2 ShortAnswer) covering all major load testing topics from ch18-03-performance.md
- Created ch18/loadtest.ai.toml exercise with 6 progressive phases, scaffolding with 6 hint triggers, 5 common mistakes, assessment criteria, discussion prompts, knowledge connections, and 3 code examples
- Both files follow existing format conventions exactly (ch17-observability.toml and ch17/metrics-collection.ai.toml)

## Task Commits

Each task was committed atomically:

1. **Task 1: Create ch18-operations quiz TOML** - `0d3f697` (feat)
2. **Task 2: Create ch18/loadtest AI-guided exercise TOML** - `3afd8b0` (feat)

## Files Created/Modified
- `pmcp-course/src/quizzes/ch18-operations.toml` - 10-question quiz covering load testing CLI, schema discovery, config structure, staged profiles, percentiles, coordinated omission, breaking point detection, VUs, init command, and capacity planning
- `pmcp-course/src/exercises/ch18/loadtest.ai.toml` - AI tutor exercise with 6 phases (connect, first_test, config_authoring, staged_profiles, metrics_interpretation, breaking_point), scaffolding, common mistakes, assessment, discussion prompts, knowledge connections, and code examples

## Decisions Made
- Used 10 questions (8 MultipleChoice, 2 ShortAnswer) to match the scope and format of ch17-observability.toml
- Exercise phases mirror the progressive structure of ch18-03: start simple (first test), build complexity (config, stages), interpret results (percentiles), find limits (breaking point)
- UUID pattern follows f18a1b2c-d3e4-5678-abcd-1234568NNNNN sequence for ch18

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Ch18 quiz and exercise complete, ready for Phase 24 Plan 02 (remaining quizzes/exercises)
- Both files follow established format conventions for course tooling compatibility
