+# Proposed amendment: allow the prerequisite proof to be produced
+
+Status: proposed; not enacted. Decision:
+`e9aca79b-f167-4326-94cd-037dcea34cd2`.
+
+## Problem
+
+The standing rule requires all four entry conditions before T03/T04, while T04
+was intended to produce condition 4. Unrelated application rollback receipts do
+not resolve this dependency. Moving the same experiment to another repo merely
+to evade the gate would not resolve it either.
+
+## Exact proposed rule
+
+Replace the all-four prerequisite for the **disposable-only portions of T03/T04**
+with these conditions:
+
+1. Entry conditions 1–3 are met and the evidence is accepted for the tested scope.
+2. railiance-forge has a file-backed, separately authorized rehearsal record
+   naming an isolated disposable instance, its product/version/configuration,
+   fixtures, permitted operations, cleanup and rollback evidence.
+3. The rehearsal uses no existing production org/repository/package, customer
+   data or production credential grant. Its GitOps and image-pull consumer is a
+   disposable fixture. Configuration differences from production are recorded.
+4. Only disposable repo transfer/rename, package behavior and recovery are
+   exercised. No existing repo is used merely because it seems low-stakes.
+5. T03/T04 evidence may satisfy condition 4 only for behavior reproduced with
+   equivalent relevant configuration; untested production-specific differences
+   remain blockers. The forge owner signs off applicability.
+
+**All four entry conditions remain required before any production transfer,
+production rehearsal, or T05 execution.** G3/G4 still need accepted behavior and
+rollback evidence; production GitOps and fresh-pull acceptance remain required
+before migration completion. This amendment changes sequencing, not evidence
+quality or production authority.
+
+## Files to change if accepted
+
+- AGENTS.md, “Before anything else”: keep the all-four production rule and add
+  the exact disposable-only exception above for T03/T04.
+- ORGREF-WP-0001 entry gate: reference the exception and keep conditions 1–4.
+- T03/T04: distinguish disposable prerequisite proof from later production
+  applicability verification; remove the requirement for prior condition-4
+  proof only from the disposable portion.
+- GOAL.md/history and State Hub decision: record the accepted amendment and
+  its scope. Do not mark any gate green merely because this rule is accepted.
+
+## Effect today
+
+None on execution readiness: conditions 2 and 3 still fail, and no owner
+rehearsal record/target has been authorized. Accepting this proposal alone would
+not permit any live action now. Until explicitly accepted, AGENTS.md and the
+original all-four rule remain unchanged.
