-version: 4.1
-# v4.1 (2026-10-04):
-#   - Append-only over v4. No schema breaks.
-#   - New MAILBOX_PATH_RE exemption in app/main.py: per-home mailbox writes
-#     (outbox/ + inbox/ under <agent>/home/mailbox/) classify AUTO_RUN
-#     when ALL targets are own-home mailbox paths. Encodes Decision 6 [1].
-#   - Cross-agent inbox mirror (CAIRO writes to coreci-coo/home/mailbox/inbox/)
-#     is still NEEDS_APPROVAL — explicit cross-agent grants land in v4.2.
-#   - Naming convention v2 preserved: agent = coreci-<role>.
+version: 5.0
+mode: approval_queue_only
+# allowlist v5.0 — approval-request queue repurpose (REQ-27, P04-04).
+#
+# CHANGE SHAPE (one-way PR into the FROZEN executor-config repo):
+#   v4.x classified packs and auto-ran granted targets. The rail is now an
+#   approval-request queue ONLY — it routes, records, mirrors, and reports;
+#   it NEVER executes against production.
+#
+# REVOKED in v5.0 (the complete v4.1 grant set — nothing else ever existed):
+#   - coreci-coo:       bash_pack auto_run coreci-coo/home        (revoked)
+#   - coreci-cairo:     bash_pack auto_run coreci-cairo/home      (revoked)
+#   - coreci-cpo:       bash_pack auto_run coreci-cpo/home        (revoked)
+#   - coreci-executor:  bash_pack auto_run coreci/executor-config (revoked)
+#   - defaults read_targets (coreci/company) kept UNCHANGED: the queue still
+#     allows the org records as a READ surface for request context only.
+#
+# SEMANTICS under mode: approval_queue_only:
+#   - defaults.decision stays NEEDS_APPROVAL (fail-closed) and there are no
+#     agent rows: the v4.1 classifier can never return AUTO_RUN again.
+#   - The v4.1 mailbox-path exemption is APP-CODE-level (not config) and
+#     cannot reach an execution path here — approval-queue mode has none
+#     (see README.md "The NEVER-EXECUTES guarantee").
+#   - approval_queue.* below is consumed by the 0.4.0 decision-only server
+#     build; the legacy 0.3.0 server ignores unknown top-level keys (its
+#     loader picks only defaults/agents), so this file is backward-safe.
+#
+# Routing for approvals comes from routing.json (GENERATED from
+# coreci/company org/systems-ownership.md v1.2 + org-chart.json — do not
+# hand-edit either side of that chain; regenerate instead).
