Derived 5 rows: one per PKG-0x success criterion from v1.0-ROADMAP.md Phase 5 (PKG-01..05). No extra historical-gap bonus rows — PKG-04 gap is recorded inside row 4 itself (not as a separate row) because the criterion wording covers both upload + embedding.
Row 2 (PKG-02 byte-level .intunewin conformance) is the STRONGEST row in the entire 7-phase Nyquist audit track. It cites 14 pytest byte-level assertions PLUS RTVAL-01 artifact-backed PASS on tenant rubis.fr (2026-04-13) with committed screenshots and the exact .intunewin package under test. The preamble explicitly calls out that RTVAL-01 initially FAILED and was fixed by commits 74535ea (HMAC over IV+ciphertext) + 7716246 (Detection.xml alignment with IntuneWinAppUtil.exe reference format) — this is the audit-trail equivalent of 'caught and fixed before real deployment'.
Row 1 (PKG-01 one-click .intunewin export) also cites RTVAL-01 but the success criterion is 'user can export'; the 'Intune accepts the package' piece is more directly owned by PKG-02. Row 1 therefore cites RTVAL-01 as supporting evidence without the structural-fix commentary (that belongs to PKG-02).
Row 4 (PKG-04 icon upload + embedding) records the historical gap IN PLACE rather than flipping to fail-fix-v1.1. Phase 5 plan 02 shipped icon upload + storage only; Phase 6 (Wire Icon into .intunewin Export) added TestIntunewinIconInclusion which closes the embedding half. This mirrors the 08-02 row 6 (drivers/upload 500 historical gap closed by Phase 9 UX-01) pattern explicitly approved in the plan 08-02 methodology.
Row 3 (PKG-03 NinjaRMM ZIP) has no Phase 10 runtime evidence and does not need any — NinjaRMM packages are opaque ZIPs fed into the customer's RMM, there is no Microsoft format spec to defend against. Template-level + HTTP-level correctness via pytest is sufficient for Nyquist. Phase 11 rollout owns real NinjaRMM execution.
Row 5 (PKG-05 command preview) cites TestCommandPreview class + template IDs + 05-VERIFICATION.md truths 9+10+11. The Alpine.js copy-to-clipboard UX remains a Manual-Only Verification (listed in 05-VERIFICATION.md 'Human Verification Required #2') and was NOT exercised in Phase 10 — Phase 10 did not cover browser reactivity. The minor 'Uninstall copy' label cosmetic issue flagged in 05-VERIFICATION.md Anti-Patterns is noted as UX polish, not a correctness defect.
No historical-gap BONUS rows (unlike 08-02 row 6). PKG-04's gap is already the 'canonical' Phase 5 row 4, not a bonus row, because the success criterion itself covers both upload and embedding.

Phase 08 Plan 05: Phase 5 Nyquist Audit Summary

One-liner: Audited Phase 5 (Package Export, PKG-01..05) against Nyquist rules and upgraded 05-VALIDATION.md in place with a 5-row Nyquist Record where PKG-02 (byte-level .intunewin conformance) becomes the first and only artifact-backed live-Intune-tenant runtime row in the entire 7-phase audit track — citing RTVAL-01 PASS on rubis.fr after commits 74535ea + 7716246 fixed the two structural defects (HMAC over IV+ciphertext, Detection.xml alignment) that caused the initial FAIL — and PKG-04's historical icon-embedding gap is recorded in place with Phase 6 closure (TestIntunewinIconInclusion) cited.

What Shipped

  • .planning/phases/05-package-export/05-VALIDATION.md now contains a ## Nyquist Record section (placed above Validation Sign-Off, below Manual-Only Verifications).
  • 5 rows: one per PKG-0x success criterion from milestones/v1.0-ROADMAP.md Phase 5 goal block (PKG-01..05).
  • Every row has a non-empty Observable Check (pytest invocation) and a non-empty Evidence cell citing committed tests, source paths with line numbers, commit SHAs, 05-VERIFICATION.md truths, and — for PKG-01 + PKG-02 — Phase 10 RUNTIME-VALIDATION.md RTVAL-01 artifact-backed PASS.
  • Row 2 (PKG-02) is the strongest row of the entire 7-phase Nyquist track: 14 byte-level pytest assertions in tests/test_intunewin.py PLUS artifact-backed tenant acceptance (screenshots rtval-01-tenant-upload.png + rtval-01-app-assigned.png, committed package Copieur_2eme.intunewin, tenant rubis.fr, test device ARES-5CG5220YTM). The preamble explicitly narrates the initial FAIL → root cause → fix → re-test PASS arc so the audit trail shows "caught and fixed before broad deployment".
  • Row 4 (PKG-04) records the icon-embedding historical gap in place and cites Phase 6 closure via tests/test_packages.py::TestIntunewinIconInclusion::test_intunewin_includes_icon + ::test_intunewin_without_icon_succeeds. Status remains pass — this mirrors the 08-02 row 6 (drivers/upload 500 → Phase 9 UX-01 closure) methodology.
  • Frontmatter updated: nyquist_compliant: false -> true, added nyquist_audited: 2026-04-13, nyquist_auditor: Claude (gsd-executor, plan 08-05).
  • All historical sections (Test Infrastructure, Sampling Rate, Per-Task Verification Map, Wave 0 Requirements, Manual-Only Verifications, Validation Sign-Off) preserved verbatim. Sign-Off checkbox for nyquist_compliant: true ticked.

Audit Outcome

Status Count
pass 5
fail-fix-v1.1 0
deferred-v1.2 0
wont-do 0

Phase 5 is Nyquist-compliant. Uniquely among the 7 v1.0 phases audited so far, Phase 5 row 2 (PKG-02) carries artifact-backed real-tenant runtime evidence via RTVAL-01 — no attestation-only caveat on this row. Rows 1 + 4 also benefit from RTVAL-01 as supporting evidence.

Evidence Strategy Used

Priority order from CONTEXT.md honored:

  1. Test evidence (preferred): 5/5 rows cite concrete pytest invocations. PKG-02 cites 14 byte-level assertions in tests/test_intunewin.py across 5 test classes (TestOuterZipStructure, TestDetectionXml, TestEncryptedBlobLayout, TestCryptographicVerification, unencrypted size). PKG-01/03 cite tests/test_packages.py (TestIntunewinDownload, TestNinjaDownload). PKG-04 cites both tests/test_icon_upload.py (upload half) and tests/test_packages.py::TestIntunewinIconInclusion (embedding half). PKG-05 cites tests/test_packages.py::TestCommandPreview.
  2. Commit/file-line evidence: imptune/api/packages.py (get_ninja_package lines 49-94, get_intunewin_package lines 97-158), imptune/generators/intunewin_builder.py (build_intunewin, AES-256-CBC, HMAC-SHA256, Detection.xml), imptune/api/icons.py (Pillow validation lines 41-74), imptune/api/pages.py (lines 102-103 command context), imptune/templates/printer_detail.html (install-cmd/uninstall-cmd IDs lines 31/40, export hrefs lines 49-50). Commits cited: a31c71e (05-01 RED), dd6cedf (05-01 GREEN), d8ce223 (05-02 icon RED), f9e13ba (05-02 icon GREEN), f96ea6f (05-02 UI), and critically 74535ea + 7716246 (the two structural fixes that flipped RTVAL-01 from FAIL to PASS).
  3. Dated manual-check evidence: 05-VERIFICATION.md (2026-04-10, 11/11 truths VERIFIED) referenced per-row for cross-traceability.
  4. Runtime evidence (artifact-backed): Phase 10 RUNTIME-VALIDATION.md RTVAL-01 PASS cited on rows 1 + 2 + 4 — with committed screenshots and package, no attestation-only caveat. Plan 10-03 sign-off (commit cd2df1e) cited as formal acceptance.

No row relied on "code looks right" or attestation-only runtime — every row has a concrete pytest invocation, and PKG-02 additionally has artifact-backed real-tenant proof.

Cross-Reference with 05-VERIFICATION.md

05-VERIFICATION.md (dated 2026-04-10) enumerated 11 observable truths covering PKG-01..05. The Nyquist Record collapses these to 5 rows (one per criterion) as follows:

  • Row 1 (PKG-01) ← truth 2 (intunewin endpoint), truth 5 (build_intunewin native), truth 3 (404/422 error paths)
  • Row 2 (PKG-02) ← truth 5 (Python-native no subprocess) + 14 tests/test_intunewin.py byte-level truths + RTVAL-01 artifact evidence
  • Row 3 (PKG-03) ← truths 1 (ZIP contains install + drivers) + 4 (DEFLATE + folder structure)
  • Row 4 (PKG-04) ← truths 6+7+8 (icon upload/validation/replace) + Phase 6 TestIntunewinIconInclusion (icon embedding half, gap closure)
  • Row 5 (PKG-05) ← truths 9 (command strings rendered) + 10 (copy buttons present) + 11 (export links present)

The "Human Verification Required" items from 05-VERIFICATION.md map as follows:

  • #1 ".intunewin byte-level Intune compatibility" → CLOSED by RTVAL-01 artifact-backed PASS (row 2)
  • #2 "Alpine.js copy-to-clipboard UX" → still Manual-Only (row 5 Notes), owned by Phase 11 rollout visual polish
  • #3 "HTMX icon upload response swap" → still Manual-Only (row 4 Notes), owned by Phase 11 rollout visual polish

Artifact-Backed Evidence Highlight (Key Point for 08-08 Rollup)

Per STATE.md 2026-04-13, Phase 10 RTVAL-01 is the only artifact-backed runtime check across the entire Phase 10 runtime half (RTVAL-02/03/04 are all attestation-only, 3 consecutive). This Phase 5 audit is therefore the unique beneficiary of strong real-tenant runtime evidence in the entire 7-phase Nyquist track. When 08-08 rolls up the milestone Nyquist summary, it should note:

  • Phase 5 PKG-02: artifact-backed runtime (committed screenshots + package + tenant confirmation)
  • Phase 5 PKG-01 + PKG-04: artifact-backed runtime via PKG-02's transitive coverage (same builder path)
  • Phase 1 row 14: artifact-backed via RTVAL-01 tenant ingestion (dev environment + infra check)
  • All Phase 4 SCRPT-0x rows: attestation-only runtime (RTVAL-02/03/04)
  • All Phase 2/3/6/7 rows: no Phase 10 runtime coverage at all (purely template/HTTP level)

The two fix commits 74535ea + 7716246 are the most important artifacts this audit surfaces — they represent real defects that real-Intune testing caught and that the team fixed before broad rollout. This is exactly the workflow Nyquist validation exists to produce.

Deviations from Plan

None. Plan 08-05 executed exactly as written. Single task, single file edit. The plan explicitly instructed: "For byte-level .intunewin conformance: cite commits 74535ea and 7716246 plus Phase 10 RTVAL-01 PASS. This is the only strong artifact-backed runtime row in Phase 10 per STATE.md." — done on row 2. The plan also instructed to consult tests/test_intunewin.py and tests/test_packages.py for test names — done via Grep to confirm TestOuterZipStructure, TestDetectionXml, TestEncryptedBlobLayout, TestCryptographicVerification, TestNinjaDownload, TestIntunewinDownload, TestCommandPreview, TestIntunewinIconInclusion.

No Rule 1-4 deviations triggered. No auth gates.

Authentication Gates

None.
