<objective>
Audit Phase 5 (Package Export, PKG-01..05) against Nyquist rules. Upgrade `05-VALIDATION.md` in place. The .intunewin byte-layout criterion gets its strongest evidence from Phase 10 RTVAL-01 (tenant ingestion PASS on fixed build, commits 74535ea + 7716246).

Purpose: Fifth of 7 per-phase audits feeding the milestone index.
Output: Upgraded `.planning/phases/05-package-export/05-VALIDATION.md`.

  <action>
    Apply the established methodology:
    1. Extract Phase 5 (PKG-01..05) success criteria from `.planning/milestones/v1.0-ROADMAP.md`.
    2. One observable check per criterion; evidence in priority order.
    3. Preserve all existing sections; append `## Nyquist Record`.
    4. For byte-level .intunewin conformance: cite commits 74535ea (HMAC over IV+ciphertext) and 7716246 (Detection.xml alignment) plus Phase 10 RTVAL-01 PASS (tenant ingestion confirmation). This is the only strong artifact-backed runtime row in Phase 10 per STATE.md.
    5. For Phase 5 test evidence, consult `tests/test_intunewin.py` and `tests/test_packages.py` (visible in git status) for test names.
    6. Update frontmatter.

  <done>
    05-VALIDATION.md has a complete Nyquist Record, byte-level conformance row cites RTVAL-01 evidence, and frontmatter is updated.

<verification>
- `## Nyquist Record` section exists in 05-VALIDATION.md
- Row count matches Phase 5 success criteria
- Byte-layout row references RTVAL-01 or commits 74535ea / 7716246
- Frontmatter has nyquist_audited + nyquist_auditor keys
</verification>

<success_criteria>
Phase 5 Nyquist audit complete.
