# Staffing Change: Foundation Reviewer R3 Environment Recovery

> Team revision: `rev-p9.1-1 -> rev-p9.1-1`
> Status: `APPLIED`
> Type: `REPLACE`
> Proposed by: `PMO / 2026-08-13T05:10:51Z`
> Approved by: `PROJECT.md pre-dispatch/environment recovery policy and Owner instruction to continue autonomously`

## Trigger Evidence

R2 stopped INVALID before product assertions because its out-of-tree probe used
an unresolved `FirstSessionState` type annotation. Fixed source `bd505d6` has no
new product judgment. R2 is archived and retired.

## Replacement

| Action | Role | Goal | Writes | Session | Runtime |
|---|---|---|---|---|---|
| replace | p91-foundation-reviewer-r3 | task:ABG-P9.1-FOUNDATION-REVIEW-R3 | none | fresh visible HAPI | Codex gpt-5.6-sol/xhigh/yolo |

R3 must create a new source archive, import it with isolated HOME/cache/TMP, and
use an annotation-free external exact-ID probe. It cannot reuse R1/R2 execution
evidence. Graph/spec/product source/permissions/concurrency remain unchanged.

## Rollback

Runtime or identity failure leaves R3 inbox and archives only its new unassigned
session. A new environment INVALID is reported without modifying product source.

Final result: `APPLIED / pre-dispatch`.
