Phase 10 Plan 03: Report Sign-off Summary

Finalized RUNTIME-VALIDATION.md, obtained human sign-off with explicit attestation-gap acknowledgement, and flipped Phase 10 tracking docs to complete.

What Was Done

Task 1 — Finalize RUNTIME-VALIDATION.md report body

Completed in the 10-02 → 10-03 handoff window: all RTVAL-01..04 sections carry concrete PASS/FAIL verdicts, evidence links, and notes; top-level Status was flipped to READY FOR SIGN-OFF by the prior agent.

Task 2 — Human review and sign-off (checkpoint)

Reviewer Sébastien QUEROL read the report, acknowledged the attestation-only audit-trail gap for RTVAL-02/03/04, and signed off on 2026-04-13:

• Top-level Status: flipped to SIGNED OFF
• Signed off by: Sébastien QUEROL
• Signed off date: 2026-04-13
• All three sign-off checkboxes ticked [x]
• Reviewer explicitly accepted that only RTVAL-01 is artifact-backed; RTVAL-02/03/04 rest on technician verbal attestation. Compensating controls listed in the report (known device, known tenant, single session, known-good generator) stand in for missing log/screenshot evidence.

Commit: 5685fd9 — docs(phase-10): human sign-off on RUNTIME-VALIDATION.md (attestation gap acknowledged)

Task 3 — Tick requirements, mark Phase 10 complete

• .planning/REQUIREMENTS.md already had RTVAL-01..05 ticked [x] and the Traceability table showing Complete for each (landed in the 10-02 completion commit 206648c). Idempotent confirmation only — no edits needed.
• .planning/ROADMAP.md:
  • Phase 10 entry flipped from [ ] to [x] with (completed 2026-04-13) appended.
  • Progress table row for Phase 10 set to v1.1 | 3/3 | Complete | 2026-04-13.

Verification

• grep "^\*\*Status:\*\* SIGNED OFF" RUNTIME-VALIDATION.md → hit
• grep "Signed off by:\*\* Sébastien QUEROL" RUNTIME-VALIDATION.md → hit
• Zero Status: PENDING lines in the report
• grep "\[x\] \*\*RTVAL-05\*\*" REQUIREMENTS.md → hit
• grep "\[x\] \*\*Phase 10" ROADMAP.md → hit
• ROADMAP.md Progress row for Phase 10 shows 3/3 | Complete | 2026-04-13

All verification checks from the plan pass.

Deviations from Plan

None. Task 3 REQUIREMENTS.md edits were already present from plan 10-02's completion commit, making that step a no-op confirmation rather than a mutation. No deviation rules (1-4) triggered.

Phase 10 Closure Note — Attestation-Only Audit Trail

Phase 10 closes with a structurally weakened runtime audit trail that downstream consumers must be aware of:

• RTVAL-01 (tenant ingestion): PASS, artifact-backed (screenshots + exact .intunewin package committed under evidence/), re-tested on the fixed build after ISSUE-01 was resolved (commits 74535ea + 7716246).
• RTVAL-02 (install under SYSTEM): PASS, attestation-only — no IntuneManagementExtension.log excerpt, no portal screenshot.
• RTVAL-03 (detection rule): PASS, attestation-only, 2nd consecutive — no portal screenshot, no manual detect transcript.
• RTVAL-04 (uninstall under SYSTEM): PASS, attestation-only, 3rd consecutive — no uninstall log, no portal screenshot.

RTVAL-02/03/04 together form an attestation-only runtime half for the phase. The user was warned twice during plan 10-02 (on RTVAL-03 and again on RTVAL-04) that consecutive attestation-only checks damage the audit trail, and chose to proceed both times. At sign-off the user again explicitly acknowledged the gap and accepted Phase 10 closure on that basis.

Implication for future work: If a regression, incident, or customer escalation touches SYSTEM-context install, detection, or uninstall, RTVAL-02/03/04 must be treated as soft PASSes — the "it worked once" claim for this build cannot be independently re-derived from evidence files and must be re-validated with full artifact capture. Phase 11 rollout proceeds at the reviewer's risk.
