decisions:

- "One row only: Phase 6 goal block in v1.0-ROADMAP.md enumerates exactly one requirement (PKG-04) and one plan (06-01). No sub-criteria to decompose. Single-row Nyquist Record is correct — padding with derived sub-rows would dilute audit signal."
|
||||
- "RTVAL-01 cited as SUPPORTING (not primary) evidence. The observable check of RTVAL-01 was 'tenant accepts .intunewin package', not 'icon appears on Intune app tile'. Primary evidence remains pytest (TestIntunewinIconInclusion x2) plus source review of imptune/api/packages.py lines 149-157 plus TDD commits 2723cc8 (RED) and 6310be5 (GREEN). RTVAL-01 is added because the test package was built with the icon-wiring code live, so Intune's successful ingestion transitively proves the icon staging does not corrupt the .intunewin output."
|
||||
- "Icon-tile visual rendering deferred to Phase 11 rollout Manual-Only polish. This mirrors 05-VALIDATION.md row 4 notes and 05-VERIFICATION.md 'Human Verification Required #3' (HTMX icon upload response swap). Cosmetic confirmation of the icon actually displaying on the Intune portal app tile is NOT needed for Nyquist compliance because the audit-level question is 'does the mechanism wire the icon into the package', which is fully proven by pytest + source review."
|
||||
- "No historical-gap row needed. Phase 6 IS the gap closure — recording the gap here would be circular. Instead, the 08-05 row 4 citation already documents the PKG-04 historical gap in place (in 05-VALIDATION.md) with Phase 6 as closure. The two VALIDATION files form a closed-loop citation graph that any reader can traverse in either direction."
|
||||
- "Shortest Nyquist Record in the 7-phase audit track so far. Audit rows by phase: Phase 1 = 14, Phase 2 = 6, Phase 3 = 10, Phase 4 = 5, Phase 5 = 5, Phase 6 = 1. Phase 7 (plan 08-07) also expected to be small because it is the other single-plan gap-closure phase (/packages 404 + dashboard wiring). The 08-08 rollup should explicitly note that row count is not a quality metric — single-criterion phases legitimately produce single-row audits."

# Phase 08 Plan 06: Phase 6 Nyquist Audit Summary
|
||||
|
||||
**One-liner:** Audited Phase 6 (Wire Icon into `.intunewin` Export — single-requirement gap-closure phase) against Nyquist rules and upgraded `06-VALIDATION.md` in place with a **1-row** Nyquist Record covering PKG-04 icon embedding, citing the `TestIntunewinIconInclusion` pair (TDD commits `2723cc8` + `6310be5`), the `shutil.copy2` staging at `imptune/api/packages.py:153` before `build_intunewin` at `:157`, and — as supporting transitive evidence — Phase 10 RTVAL-01 artifact-backed tenant acceptance of the exact builder path with icon wiring live.
|
||||
|
||||
## What Shipped
|
||||
|
||||
- `.planning/phases/06-wire-icon-intunewin/06-VALIDATION.md` now contains a `## Nyquist Record` section (placed above Validation Sign-Off, below Manual-Only Verifications — same position as prior audits).
|
||||
- **1 row:** PKG-04 icon embedding. Phase 6 has exactly one success criterion in `v1.0-ROADMAP.md` and one plan (06-01), so the Nyquist Record is intentionally single-row.
|
||||
- Row evidence:
|
||||
- **Primary:** `tests/test_packages.py::TestIntunewinIconInclusion::test_intunewin_includes_icon` (lines 200-231) + `::test_intunewin_without_icon_succeeds` (lines 233-245). Monkeypatched `build_intunewin` captures staged file list, asserts `icon.png` present.
|
||||
- **Source:** `imptune/api/packages.py` line 149 (`Icon.get_or_none`), line 151 (`cfg.ICONS_DIR`), line 153 (`shutil.copy2` as `icon.png`), line 157 (`build_intunewin` call — staging-before-build ordering confirmed), imports at line 13.
|
||||
- **Commits:** `2723cc8` (06-01 TDD RED, failing test) + `6310be5` (06-01 TDD GREEN, 4-line icon staging block).
|
||||
- **Dated manual check:** 06-VERIFICATION.md (2026-04-10) — 2/2 truths VERIFIED, all key links WIRED, PKG-04 SATISFIED, zero anti-patterns, 96/96 full suite green.
|
||||
- **Supporting transitive runtime:** Phase 10 `RUNTIME-VALIDATION.md` RTVAL-01 PASS on tenant rubis.fr (2026-04-13) — same `build_intunewin` path with icon-wiring code live; tenant accepted package `Copieur_2eme.intunewin` after fix commits `74535ea` + `7716246`.
|
||||
- **Status:** pass (1/1).
|
||||
- Frontmatter: `nyquist_compliant: false -> true`, added `nyquist_audited: 2026-04-13`, `nyquist_auditor: Claude (gsd-executor, plan 08-06)`.
|
||||
- All Phase 6 existing sections preserved verbatim (Test Infrastructure, Sampling Rate, Per-Task Verification Map, Wave 0 Requirements, Manual-Only Verifications). Sign-Off checkboxes ticked.
|
||||
|
||||
## Audit Outcome
|
||||
|
||||
| Status | Count |
|
||||
|---------------|-------|
|
||||
| pass | 1 |
|
||||
| fail-fix-v1.1 | 0 |
|
||||
| deferred-v1.2 | 0 |
|
||||
| wont-do | 0 |
|
||||
|
||||
Phase 6 is Nyquist-compliant. Shortest Nyquist Record in the 7-phase audit track — a legitimate reflection of the phase's single-criterion gap-closure structure, not an audit quality deficit.
|
||||
|
||||
## Evidence Strategy Used
|
||||
|
||||
Priority order from CONTEXT.md honored:
|
||||
|
||||
1. **Test evidence (primary):** `TestIntunewinIconInclusion` pair in `tests/test_packages.py`. Both tests concrete, both passing, one is the canonical RED-to-GREEN TDD assertion.
|
||||
2. **Commit/file-line evidence:** `imptune/api/packages.py:149-157` (Icon lookup → ICONS_DIR path → shutil.copy2 → build_intunewin ordering). TDD commits `2723cc8` + `6310be5` explicitly cited.
|
||||
3. **Dated manual-check evidence:** 06-VERIFICATION.md (2026-04-10) — 2/2 truths VERIFIED with line-number citations back to test_packages.py.
|
||||
4. **Runtime evidence (transitive, supporting only):** RTVAL-01 cited as supporting because its observable check targeted tenant ingestion, not icon-tile visual rendering. Still valuable because the test package was built with icon wiring live, so successful ingestion transitively proves the icon staging does not corrupt the `.intunewin` output.
|
||||
|
||||
No row relied on "code looks right" alone.
|
||||
|
||||
## Bidirectional Gap-Closure Citation Loop
|
||||
|
||||
Phase 5 VALIDATION row 4 cites the Phase 6 `TestIntunewinIconInclusion` tests as its "closed by" evidence for the PKG-04 historical gap. Phase 6 VALIDATION row 1 cites the same tests as its canonical primary evidence. Readers traversing either direction land on the same proof, forming a closed loop. This is the first time in the audit track where two adjacent phase VALIDATION files reference each other's closure evidence — a pattern worth highlighting in 08-08 rollup as a model for future gap-closure phases.
|
||||
|
||||
## Cross-Reference with 06-VERIFICATION.md
|
||||
|
||||
06-VERIFICATION.md (2026-04-10) enumerated 2 observable truths, both VERIFIED:
|
||||
|
||||
- Truth 1 (icon.png in staging when icon uploaded) ← Nyquist row 1 primary evidence (test_intunewin_includes_icon)
|
||||
- Truth 2 (export succeeds without error when no icon) ← Nyquist row 1 primary evidence (test_intunewin_without_icon_succeeds baseline)
|
||||
|
||||
Both collapse into the single Nyquist row because both test the same PKG-04 criterion from complementary angles (positive + baseline).
|
||||
|
||||
No "Human Verification Required" items in 06-VERIFICATION.md — the only residual manual item (does the icon actually render on the Intune portal app tile) is tracked in 05-VALIDATION.md row 4 notes and 05-VERIFICATION.md "Human Verification Required #3", consistent with where the upload UX originates.
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
**None.** Plan 08-06 executed exactly as written. Single task, single file edit. The plan explicitly anticipated that Phase 6 success criteria "may be narrower than the earlier build phases — audit what actually exists there" — confirmed: exactly 1 criterion, 1 row. `ls .planning/phases/06-wire-icon-intunewin/` returned a single plan (06-01), consistent with the plan's single-plan expectation.
|
||||
|
||||
No Rule 1-4 deviations triggered. No auth gates.
|
||||
|
||||
## Authentication Gates
|
||||
|
||||
None.
|
||||
|
||||
## Task Commits
|
||||
|
||||
1. **Task 1: Build Phase 6 Nyquist Record and upgrade 06-VALIDATION.md** — `bb62174` (docs)
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
- `.planning/phases/06-wire-icon-intunewin/06-VALIDATION.md` — added `## Nyquist Record` section (1 row, preamble, outcome table), updated frontmatter (`nyquist_compliant: true`, `nyquist_audited`, `nyquist_auditor`), ticked Sign-Off checkboxes
|
||||
- `.planning/phases/08-nyquist-validation-track/08-06-SUMMARY.md` — this file
|
||||
|
||||
## Next Phase Readiness
|
||||
|
||||
- 6/8 plans of Phase 08 complete (08-01..08-06 audited: Phases 1, 2, 3, 4, 5, 6)
|
||||
- Remaining: 08-07 (Phase 7 gap-closure audit — dashboard + `/packages` route), 08-08 (milestone rollup index)
|
||||
- 08-07 should be similarly concise: Phase 7 is also a single-plan gap-closure phase (no v1.0 requirements, pure UX/integration fixes). Expect 1-3 rows depending on whether 08-07 decomposes the goal into observable sub-checks.
|
||||
- 08-08 rollup should note:
|
||||
- Phase 5 PKG-02 = only artifact-backed live-tenant runtime row in the track (strongest row)
|
||||
- Phase 6 PKG-04 = bidirectional gap-closure citation loop with 05-VALIDATION row 4
|
||||
- Row count is not a quality metric — single-criterion phases legitimately produce single-row audits
|
||||
|
||||
