# Phase 11 Plan 02: CLI IPD Commands Summary

**CLI tool updated with production IPD commands (ipd, ipd?, load_lh_config) and all spike/legacy commands removed**

## Performance

- **Duration:** 3 min
- **Started:** 2026-03-26T02:50:21Z
- **Completed:** 2026-03-26T02:53:00Z
- **Tasks:** 1 of 2 (paused at checkpoint:human-verify)
- **Files modified:** 1

## Accomplishments
- Updated CLI command validation to accept ipd <mm>, ipd?, and load_lh_config <path>
- Removed all spike commands (ipd_test, eyetohead_check, slider_test, eyetohead_set) and legacy commands (fallback1 on/off)
- Updated PrintUsage with production command documentation
- Updated file header comment with IPD usage examples
- Build passes with zero errors

## Task Commits

Each task was committed atomically:

1. **Task 1: Update CLI command validation and usage text** - `7b8900c` (feat)

## Files Created/Modified
- `src/ctl/main.cpp` - CLI tool: updated command validation, usage text, header comments for production IPD commands

## Decisions Made
- Used strncmp prefix matching for commands that take arguments (ipd <mm>, load_lh_config <path>) and strcmp for exact-match commands -- follows existing pattern used for proximity commands

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- Build directory did not exist in worktree; configured CMake before building (expected for fresh worktree)

## Checkpoint: End-to-End Pipeline Verification

Task 2 is a human-verify checkpoint requiring SteamVR + Beyond 2 HMD connected for end-to-end IPD pipeline testing. See plan for full verification steps.

## Next Phase Readiness
- CLI tool ready for end-to-end testing with updated driver
- Pending human verification of full IPD pipeline (set, query, status, validation, config loading)
