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.

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.

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
