# Phase 08 Plan 01: Phase 1 Nyquist Audit Summary

**One-liner:** Audited Phase 1 (Foundation) against Nyquist rules and upgraded `01-VALIDATION.md` in place with a 14-row Nyquist Record where every success criterion maps to exactly one observable check with committed evidence.

## What Shipped

- `.planning/phases/01-foundation/01-VALIDATION.md` now contains a `## Nyquist Record` section (placed above Validation Sign-Off, below Manual-Only Verifications).
- 14 rows, one per Phase 1 success criterion derived from `milestones/v1.0-ROADMAP.md` Phase 1 goal + the outcomes of plans 01-01, 01-02, 01-03.
- Every row has a non-empty Observable Check cell (pytest invocation, grep, or dated VERIFICATION.md reference) and a non-empty Evidence cell citing committed tests, source `file:line`, commit SHAs, or 01-VERIFICATION.md rows.
- Row 14 is the former "Upload to real Intune tenant" spike that lived in the Manual-Only Verifications table — now closed as `pass` citing Phase 10 RTVAL-01 re-test sign-off (2026-04-13).
- Frontmatter updated: `nyquist_compliant: true`, `nyquist_audited: 2026-04-13`, `nyquist_auditor: Claude (gsd-executor, plan 08-01)`.
- All historical sections (Test Infrastructure, Sampling Rate, Per-Task Verification Map, Wave 0 Requirements, Manual-Only Verifications, Validation Sign-Off) preserved verbatim.

## Audit Outcome

| Status | Count |
|--------|-------|
| pass | 14 |
| fail-fix-v1.1 | 0 |
| deferred-v1.2 | 0 |
| wont-do | 0 |

Phase 1 is Nyquist-compliant. Zero gaps carry forward into 08-08 (rollup).

## Evidence Strategy Used

Priority order from the plan was honored:
1. **Test evidence** (preferred): used for 10/14 rows — `tests/test_health.py`, `tests/test_static.py`, `tests/test_db.py` (4 tests), `tests/test_intunewin.py` (8 tests).
2. **File-line / commit evidence**: used for Dockerfile rows (rows 2, 5), `base.html` nav sidebar (row 4), and `database.py` / `docker-compose.yml` wiring (row 8). Commits cited include 34c7cb3, 88d9c5f, 25f82e6, 74535ea, 7716246.
3. **Dated manual-check evidence**: row 14 cites Phase 10 `RUNTIME-VALIDATION.md` RTVAL-01 PASS (2026-04-13) and the committed evidence artifact `evidence/Copieur_2eme.intunewin`.

No row relied on "code looks right" — every check is observable.

## Cross-Reference with 01-VERIFICATION.md

`01-VERIFICATION.md` (dated 2026-04-10) already enumerated 13 observable truths grouped by sub-plan. The Nyquist Record adopts those 13 as rows 1–13 with their exact evidence and adds row 14 for the runtime upload gate. This keeps the two documents 1:1 alignable: rows 1–13 of Nyquist Record = truths 1–13 of 01-VERIFICATION.md.

## Deviations from Plan

**None.** Plan 08-01 executed exactly as written. Single task, single file edit.

Minor interpretive choice (within plan latitude): row 14 was originally expected to be `fail-fix-v1.1` at audit time per the plan's Task 1 step 6. However, because Phase 10 RTVAL-01 is already **Complete** in REQUIREMENTS.md (resolved 2026-04-13 with artifact), the plan itself says "this can likely resolve to `pass`". Auditor chose `pass` on that basis, with a Notes cell documenting the would-be-gap and the fixing phase reference.

## Authentication Gates

None.

## Self-Check: PASSED

- `.planning/phases/01-foundation/01-VALIDATION.md` — FOUND (modified)
- `## Nyquist Record` heading — FOUND in file
- `nyquist_audited:` frontmatter key — FOUND in file
- Commit `d37a196` — FOUND in `git log`
- No source code files touched (plan constraint) — verified via `git show --stat d37a196` (only `01-VALIDATION.md`)
