# Phase 10: Nyquist Validation Coverage - Context

**Gathered:** 2026-03-24
**Status:** Ready for planning
**Mode:** Auto-generated (infrastructure phase — discuss skipped)

<domain>
## Phase Boundary

Create VALIDATION.md artifacts for all 7 implemented phases (01–07) to achieve full Nyquist compliance, providing structured test-evidence mapping for every phase requirement. Uses the gsd-nyquist-auditor agent (State B: reconstruct from phase artifacts) for each phase. Phase 8 and 9 are gap-closure/metadata phases with no independent requirements and do not need VALIDATION.md.

## Implementation Decisions

### Claude's Discretion
All implementation choices are at Claude's discretion — pure infrastructure/documentation phase. Use the VALIDATION.md template, existing PLAN/SUMMARY artifacts, and actual test files in the repo to reconstruct accurate test-evidence mappings for each phase.

## Existing Code Insights

### Reusable Assets
- VALIDATION.md template at `$HOME/.claude/get-shit-done/templates/VALIDATION.md`
- Phase artifacts: PLAN.md and SUMMARY.md files exist for phases 01–07 in `.planning/phases/`
- Test suite: pytest-based, located under `tests/` directory
- gsd-nyquist-auditor agent: reconstructs VALIDATION.md from phase artifacts (State B flow)

### Established Patterns
- Each VALIDATION.md lives in the phase directory as `{padded_phase}-VALIDATION.md`
- Frontmatter: `phase`, `slug`, `status`, `nyquist_compliant`, `wave_0_complete`, `created`
- Content maps task IDs → requirement IDs → test file + command evidence
- `nyquist_compliant: true` set when all requirements have COVERED status

### Integration Points
- Nyquist audit tool reads VALIDATION.md files to determine compliance status
- Phase directories: `.planning/phases/01-foundation/` through `.planning/phases/07-network-node-fault-injection/`
- Plan grouping per ROADMAP: phases 01/02/03 in plan 10-01, phases 04/05 in plan 10-02, phases 06/07 in plan 10-03

<specifics>
## Specific Ideas

No specific requirements — open to standard approaches. Follow the VALIDATION.md template exactly. For retrospective phases where Wave 0 is not applicable, mark wave_0_complete: true and note "Existing infrastructure covers all phase requirements."

## Deferred Ideas

None — discussion stayed within phase scope.
