+## Tell a usage-limit refusal from a real reply
+
+**What.** A member can end its turn without calling `bridge_reply`. The bridge then scrapes the pane
+and hands that text back as the answer. Sometimes that text is not an answer at all — it is the
+backend refusing, because the account hit its usage limit. With this on, the bridge matches the scrape
+against a pattern you configure. On a match it resolves the send as `BACKEND_EXHAUSTED` and carries the
+matched line as the reason, instead of passing a refusal off as a completed reply.
+
+**On.** Per profile, `exhaustedPattern:` — a regex. Opt-in: leave it out and that profile's completion
+fallback behaves exactly as before. Startup logs one line naming which profiles have a pattern and
+which do not, so you can see the coverage without reading the config by hand.
+
+**Why.** The old behaviour lied in the worst direction. A lead asked for work, got back a block of
+text, and had no way to tell "here is your answer" from "my account is refusing to run". The lead
+would then treat a refusal as a result. Keeping the pattern in config, never in Java, is deliberate:
+every backend words its refusal differently, so a sentence baked into the code would only ever match
+one vendor.
+
+**Gotcha.** The pattern map is built once at startup from the config snapshot, so `exhaustedPattern`
+is a **deferred** key — adding one to a profile does nothing until the daemon restarts.
+`bridged.example.yaml` does not say this yet. Also, this stage only *classifies*. Nothing yet stops
+the fleet spawning another member onto the same exhausted account, and nothing yet saves the work that
+member was doing — those are stages B and C of CB-578.
+
+---
+
+## See which charter a member got
+
+**What.** Every member launch records a `CharterReceipt`: the role, where the charter came from, a
+sha-256 digest of it, and its size in bytes. It is stored on the session and shown in the roster
+(`bridge_list` and `GET /members`). The charter text itself is never recorded.
+
+**On.** Automatic.
+
+**Why.** Charters are per-role config and are re-read on every spawn, so two members of the same role
+can get different text without anyone noticing. The digest answers "did this member actually get the
+charter I think it got?" without printing prompt text into logs an operator may not be allowed to
+keep. It also closed a real leak: the older pane-placement spawn log printed the whole `argv`, and the
+charter travels inside `argv`. That argument is now replaced by its digest.
+
+**Gotcha.** `PeerHandle.charterReceipt()` is deliberately **not** a `default` method. It used to be,
+and `OpenCodeLauncher`'s wrapping handle forgot to override it — so it answered `null` while the real
+receipt sat on its delegate, and `sol` and `terra` silently showed no receipt at all while Claude Code
+members showed one. Nothing failed; the roster field was just quietly missing. Removing the `default`
+makes the compiler catch that, and any new adapter must now answer the question on purpose. If you add
+a `PeerHandle` implementation, this is the line that will not let you skip it.
