fix(10-02): record RTVAL-01 fail — Intune cannot parse generated .intunewin

- RTVAL-01 status set to FAIL: Win32 app wizard fields stayed empty, OK greyed out
- Verbatim technician symptom quoted verbatim in report
- Interpretation: Detection.xml / package metadata malformed or missing in .intunewin archive
- RTVAL-02, RTVAL-03, RTVAL-04 marked BLOCKED (all depend on RTVAL-01 PASS)
- ISSUE-01 raised in Issues Found with root cause hypothesis and resolution path
- Plan 10-02 stopped; gap-closure cycle required before retesting

 ## RTVAL-01 — Tenant ingestion
-Status: PENDING
+Status: FAIL
-Evidence: (screenshot path)
+Tested: 2026-04-13
-Notes:
+Evidence: No screenshot captured — the Intune upload form never reached a populated state. UI remained empty; there was no visible error banner to screenshot.
+Verbatim symptom (technician): "The intunewin package cant be uploaded, the OK button is greyed out and none of the fields (name, platform, size, mam enabled) gets populated."
+Interpretation: Intune accepted the file transfer but was unable to parse its embedded Detection.xml / package metadata. The Win32 app creation wizard stalls in this state when the .intunewin content manifest is malformed or when the embedded `detection.xml` is missing or structurally invalid. This is a structural defect in the package that ImpTune is generating — exactly the runtime gap RTVAL-01 is designed to catch. No portal error banner was shown because the failure occurs silently during client-side metadata extraction.
+Package tested: Copieur_2eme.intunewin (SHA256 0aac31ff190d21cbb4c76a81d4ad32657a5a3298e7e3fcc79a080e87cf40c333, ImpTune commit 1c3f458)
 
 ## RTVAL-02 — Install under SYSTEM (pnputil + $PSScriptRoot)
-Status: PENDING
+Status: BLOCKED — depends on RTVAL-01 PASS; RTVAL-01 returned FAIL (Intune cannot parse generated .intunewin). Cannot proceed until package structure defect is resolved.

+### ISSUE-01: .intunewin package metadata unreadable by Intune Win32 app wizard
+- **Discovered:** 2026-04-13 during RTVAL-01
+- **Severity:** Blocker — prevents all downstream RTVAL checks (02, 03, 04)
+- **Symptom:** Win32 app creation wizard fields (name, platform, size, MAM enabled) remain empty after file upload; OK button stays greyed out; no portal error shown
+- **Root cause hypothesis:** Detection.xml embedded inside the .intunewin archive is missing, malformed, or uses an unexpected schema version. The IntuneWin32App packager requires a valid `detection.xml` at the root of the archive alongside the content folder.
+- **Affected file:** Copieur_2eme.intunewin (evidence/Copieur_2eme.intunewin)
+- **Affected code:** ImpTune .intunewin generator (commit 1c3f458)
+- **Resolution path:** Debug the generator to verify Detection.xml is being created, embedded, and follows the expected Intune Win32 app manifest schema. Recommended: run `/gsd:debug` on the .intunewin generator, OR let phase verification surface this as a gap and use `/gsd:plan-phase 10 --gaps` to draft a gap-closure plan.
+- **Status:** Open — plan 10-02 stopped; gap-closure cycle required before retesting
