# Staffing Change: Foundation Reviewer R5 Tool-Policy Recovery > Team revision: `rev-p9.1-1 -> rev-p9.1-1` > Status: `APPLIED` > Type: `REPLACE` > Proposed by: `PMO / 2026-08-13T05:47:00Z` > Approved by: `PROJECT.md environment recovery policy and Owner instruction to continue` R4 stopped INVALID before `/bin/bash` and before all product gates because its preflight command contained an `rm -f`-style cleanup operation rejected by the execution control. R5 is an equal reviewer replacement: fixed `bd505d6`, writes none, fresh HAPI/session/archive/evidence. It must prohibit `rm` and `unlink`, verify an absolute `/private/tmp/abg-p91-foundation-r5-*` prefix, and use `/usr/bin/find "$review_root" -depth -delete` directly from `/bin/bash` for its preflight and final cleanup. Graph/spec/source/permissions/concurrency are unchanged. Rollback: any preflight/runtime/identity failure leaves R5 inbox or INVALID and does not modify product source. Final result: `APPLIED / pre-dispatch`.
