**Verdict: do not approve the dormant merge at `f624686e`. One new P2.**

**P2 — Replacement targets never activate their new install guard.** [relocationinstall.go:504](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/region-ha-1b-next-build/internal/host/relocationinstall.go:504)

Replacing a target at `installed`, or in `probing` before P opens, resumes at `installed` with a fresh stamp. The participant calls `InstallLocal`, which requires that stamp already active. Activation runs only through the build at `installing`; its authority check also accepts only that phase.

Main’s reconciler cannot fill the gap: [reconcile.go:212](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/region-ha-1b-next-build/internal/hostbox/reconcile.go:212) explicitly refuses the relocating executor’s activation path. Wake activation happens after admission, which requires completing this installation first. A fresh replacement therefore fails with `ErrNoRecord`; an existing mismatched record fails with `ErrStampMismatch`. **It stalls; it does not proceed unguarded.**

The new regression fixture masks this by [calling `Guard.Activate` directly](/home/paulca/amadan.net/carlos/platform/.claude/worktrees/region-ha-1b-next-build/internal/host/relocationprobefiles_linux_test.go:124). Add production activation for the replacement’s unopened installation, preserving the local-authority checks and retired-stamp refusal, and test the participant path without fixture activation.

Round 7’s stamp-binding P2 is closed: the prepared manifest binds P’s build stamp, while the receipt and installation journal bind the replacement’s stamp. Equality remains valid for the original target; replacement stamps are later. No other new findings in the two diffs. The release-test change matches `VerifyHeldLive`’s current implementation.

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

---

**FIRST PROMPT:**
Review round 8 at `f624686e`, read-only, without the full host suite.

**WHAT:**
Assess the stamp fix, replacement guard activation, and dormant-merge readiness.

**STATUS:**
Round 7 finding closed; one new P2 blocks approval.

**NEEDED:**
Nothing for this review.

**RECOMMENDED:**
Fix replacement guard activation and test without direct fixture activation.

**SESSION:**
Safe to close; no files changed or background processes started.
