 Three independent live instances in a single session — format gate, agent context reset, queue guard —
 is the class confirmed, not anecdote.
 
+### D-10 — the queue guard's failure modes are exactly backwards
+
+`ci-queue-wait.sh` — a **required** pre-push/pre-merge gate — was observed this session doing both of
+these:
+
+- **Fails OPEN on an unknown result.** `state=unknown ⇒ exit 0`, five times, during real pushes and
+  real merges. It also evaluates `branch=main` rather than the branch being acted on.
+- **Fails CLOSED on credential resolution.** In a worker seat it aborted with
+  `Gitea token not found`, hard-blocking a legitimate push of completed, tested work. The worker
+  correctly stopped (Constitution gate 8). The identical command run from that worker's _own worktree_
+  in another shell succeeded, so the checkout and remote were fine — the difference was the worker's
+  process environment.
+
+**A gate that waves through work it never checked, and blocks work that is ready, has its failure
+modes inverted.** Availability failures (cannot reach the provider, cannot resolve a credential)
+should degrade to a loud, auditable _inability to assert_ — never to a hard stop on delivery, and
+never to a silent pass. Correctness failures (unknown, malformed, terminal-failure) are what must
+block.
+
+This is also the **Pi-brick shape** (P-RECOVERY-001): a gate whose own unavailability prevents the
+work needed to recover from it.
+
+**Requirement on RM-03, extending its existing two defects:** the guard must distinguish
+`CANNOT_ASSERT` (credential/transport/provider unavailable — loud, audited, does not silently pass and
+does not permanently block) from `ASSERTED_NOT_READY` (a real non-green CI state — blocks). Both are
+registered R-002 cases with must-fail controls; neither may exit 0 silently.

 ### D-9 — the comms path shell-interprets message bodies (injection-shaped, found by accident)
 
 Sending a status message with `agent-send.sh -m "...`backticks`..."` caused bash to **execute** the
