+# A3-IM07 publication and owner acceptance
+
+3 November 2026. Implementation `fba80ef346bc021e675024638dacf9ccef7243db` on `codex/a3-ui-07` was pushed successfully and independently verified by remote ref readback. Committed workspace manifest verification matched all28 sources and169 evidence entries;80 final static-export assets are separately hashed. Earlier calendar subpackage194e01ed was also published/read back; it is not an additional test total.
+
+Owner then explicitly answered **"Approve calendar/documents/mail and A3-IM08"**. IM07 Gate F is ACCEPTED; do not ask again. Next authorised scope is contextual AI presentation and Settings automation, retaining manual fallback, explicit consent/review/apply, stale-input protections, usage/limits, errors/retry/cancel and accurate per-rule controls. No live model activation or production/provider operation is approved by this UI milestone.
+
+Evidence: [WORKSPACE_VALIDATION.md](WORKSPACE_VALIDATION.md).108 unique selected frontend cases/eight suites,52 backend cases,144 scoped axe scans/captures,32 controlled journey executions. Browser draft-save/send responses were intercepted fixtures, not real deliveries. Independent reviewer70 plus earlier7 overlap, not extra cases. Actual interview scheduling and original source date precision/timezone metadata remain explicit data-model gaps; owner milestone acceptance does not fabricate those capabilities or waive their qualification.
+
+Full Phase10/Product Review/Global Jobs/European localisation, physical/native/live-service, final integrated security/recovery/release qualifications remain open. Root security policy de3d5031 remains isolated. No orchestrator use, pre-P10 edit, main merge or production deployment. Feature refs UI01–07 remain preserved; next branch isolates UI08 from this checkpoint.
