**No new P1/P2/P3 findings. Round 8’s P2 is closed at `24a0abe7965e3551b06790ddfaa48ee145d649ce`.**

The install now activates the replacement’s guard before capturing it at [relocationinstall.go:547](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/region-ha-1b-next-build/internal/host/relocationinstall.go:547). The revised fixture exercises the participant path without direct guard activation.

The widened authority is appropriately narrow: only `installed` or `probing` before P opens, for the current executor and named target, with matching install stamp and main’s local checks. Retired and older stamps remain refused. Activation rereads the claim under the guard lock; subsequent installation writes recheck authority, so a replacement race does not authorize stale installation work.

**Verdict: relocation may merge dormant, subject to the required green CI gates.** Existing activation gates remain applicable.

Static review only. `git diff --check` and formatting checks passed. No tests run, including the full `internal/host` suite.

**FIRST PROMPT:**
Review round 9 at `24a0abe7965e3551b06790ddfaa48ee145d649ce`, read-only, without the full host suite.

**WHAT:**
Check replacement activation and dormant-merge readiness.

**STATUS:**
Review complete; round 8 finding closed; no new findings.

**NEEDED:**
Nothing for this review.

**RECOMMENDED:**
Proceed through the dormant-merge workflow once required CI is green.

**SESSION:**
Safe to close; no files changed or processes started. Existing untracked files remain untouched.
