+# PR_26175_CHARLIE_026 Manual Validation Notes
+
+## Orphan Branch Review
+
+The orphaned branch contained governance updates for environment model, storage model, Team Charlie System Health ownership, and cancelled environment-isolation work. Current `main` already contains later System Health v1 implementation and closeout documentation, so this PR brings forward only the remaining governance gap:
+
+- detailed Team Charlie System Health ownership bullets
+- cancelled/not-doing Environment Isolation & Developer Experience language
+
+## Manual Checks
+
+- Confirmed `team_ownership.md` now lists the System Health sub-ownership areas.
+- Confirmed `BACKLOG_MASTER.md` separates cancelled environment-isolation/runtime-port work from active backlog items.
+- Confirmed `MASTER_ROADMAP_FEATURES.md` includes matching cancelled/not-doing language.
+- Confirmed no runtime, UI, API, or database files were changed.

+# PR_26175_CHARLIE_026-charlie-governance-gap-closeout
+
+## Summary
+
+Closed the remaining Team Charlie governance gap identified by the workstream audit.
+
+## Source Reviewed
+
+- Orphaned branch: `origin/PR_26175_CHARLIE_006-project-instructions-system-health-infrastructure`
+- Current base: `origin/main`
+
+## Changes
+
+- Added detailed Team Charlie System Health ownership bullets to active team ownership governance.
+- Added cancelled/not-doing backlog language for Environment Isolation & Developer Experience.
+- Added matching roadmap cancelled/not-doing language so roadmap and backlog stay aligned.
+
+## Scope Guardrails
+
+- Runtime files changed: none.
+- UI files changed: none.
+- API files changed: none.
+- Database files changed: none.
+- Superseded System Health implementation planning was not brought forward.
+
+## Validation
+
+- PASS: `git diff --check`
+- PASS: docs/governance-only changed-file check
+- PASS: System Health ownership bullets are present
+- PASS: cancelled/not-doing language is present in backlog and roadmap
+- PASS: runtime files unchanged
+
+## Mergeability Review
+
+- GitHub reported `mergeable=false` after `origin/main` advanced beyond the PR base.
+- Local merge probe confirmed the only conflicts were shared generated report artifacts: `docs_build/dev/reports/codex_changed_files.txt` and `docs_build/dev/reports/codex_review.diff`.
+- Resolved by applying the Charlie-only governance diff onto latest `origin/main` and regenerating the shared Charlie report artifacts from the final diff.
