CB-599: surface a capacity refusal's reason instead of a bare 500

PlacementException extends IllegalStateException, which neither BridgedApp
nor BridgeMcp's spawn catch blocks handled, so a maxLoad/quarantine/
all-exhausted refusal fell through to a blank 500 on REST and lost its
message on MCP. Catch it on both surfaces, ahead of the unrelated
IllegalArgumentException(unknown_profile) mapping, and return its message
structured: REST as {"error":"no_capacity","detail":...} with status 503,
MCP as an isError result prefixed "no capacity: ...".

+### Redeploying the daemon — the lead may do this (primary only)
+
+**A merge is not a deployment.** The running `bridged` holds the jar it was started with, so a
+feature merged to `main` does nothing until the daemon is rebuilt and restarted. Saying "shipped"
+about code the live daemon has never loaded is a false report. The lead **may and should** redeploy
+rather than hand the job back to the operator.
+
+Workers must never do this. A worker has no business restarting the daemon it is talking through,
+and stopping it kills the worker's own channel mid-turn.
+
+**Use the script — do not hand-roll the steps.**
+
+```bash
+scripts/redeploy-bridged.sh --check   # report state, change nothing
+scripts/redeploy-bridged.sh           # build, confirm drain, restart, verify
+scripts/redeploy-bridged.sh --yes     # skip the drain prompt (fleet already checked)
+```
+
+It builds before it stops anything, so a failed build never leaves the fleet down; it waits for the
+old process to exit rather than assuming; it polls `/healthz`; and it anchors its log checks to a
+line marker taken before the restart, so old errors cannot be misread as new ones. Run `--check`
+first — it is read-only and reports whether the forge token resolves, which nothing else tells you.
+
+The script encodes the five things below, each of which has gone wrong here before. Read them anyway:
+if the script is unavailable or a step fails, this is what it was protecting you from.
+
+1. **Login shell, or workers silently lose their forge token.** The daemon inherits
+   `WORKER_GITEA_TOKEN` from the shell that starts it, and that comes from
+   `${SHARED_ENV}/tools/secrets.sh`. Start it from a non-login shell and the variable is empty, the
+   daemon starts fine, and the failure appears much later as workers that cannot open a PR. Nothing
+   logs this at startup — the script's `--check` is the only thing that reports it, and it checks
+   whether the name resolves without ever printing the value.
+2. **Drain live members first.** `bridge_list`, then `bridge_stop` each member, and collect anything
+   you still want with `bridge_poll` before you kill anything. A restart drops in-flight tickets and
+   rendezvous, and a member's report is not recoverable once its ticket is gone.
+3. **A restart is the only way deferred config keys take effect.** That is usually the reason to do
+   it. The startup log names which keys it accepted and which it deferred — read those lines rather
+   than assuming.
+4. **Re-check identity afterwards.** Call `bridge_whoami` and confirm it still answers `primary`. The
+   lead is found by its tab label (`fleet.leaders.*.tab`), and a lead whose tab no longer matches is
+   demoted to worker, which refuses every orchestration call.
+5. **Prove the new jar is the one running.** Confirm a *fresh* `bridged listening` line at the end of
+   `bridged/bridged.out`, dated after the restart. An old daemon that never died looks identical from
+   the outside.
+
+**Permission.** A `CLAUDE.md` rule grants intent, not tool permission — the command classifier
+refuses a bare `kill` on the daemon whatever this file says. The script is the seam that fixes that:
+it is one auditable command, so the operator allow-lists it once instead of approving a stop and a
+start every time. The rule lives in the operator's Claude Code settings:
+
+```json
+{ "permissions": { "allow": ["Bash(scripts/redeploy-bridged.sh:*)"] } }
+```
+
+Granted by the operator on 2026-08-15. If a call is still refused, do **not** route around it by
+running the stop and start as separate commands — that is exactly the approval the script replaced.
+Say what you were going to run and why, and let the operator decide.

+# THE FLEET (CB-557) — who the daemon may run, and under which role. This one block replaced four

+# A member is anything a lead spawns, and every member has two INDEPENDENT attributes:
+#   role    — which contract: architect, dev or reviewer. It picks the launch charter, the role
+#             file, the playbook skill and the authz row.
+#   profile — which backend: one of the `profiles:` keys above (model, CLI adapter, cost).
+# They vary on their own. A reviewer may run on the same profile as the dev whose diff it reads,
+# which is why the two cannot be one field.
+#
+# The ROLE IS THE CONTAINING KEY, not a `role:` field. That is not only tidier: a misspelled role
+# used to parse into a member with no contract at all, while a misspelled pool name here simply
+# declares nothing.
+#
+# Each pool lists the profiles that role MAY run on — these are pools, not identities. That is also
+# what replaced `defaultProfile:`: an unqualified spawn names a role, and that role's pool supplies
+# the candidates, in definition order. A dev and a reviewer staying anonymous is exactly compatible
+# with being listed here; the entry key just names the entry.

+  # inside it restarts — the terminal id changes; the tab, and its label, do not, so no config edit

+ * The daemon's live configuration, re-readable without a restart (CB-559).
+ *
+ * <p>Consumers hold this, not a {@link BridgedConfig}, and read through {@link #get()} at the point
+ * of use. A component that captures {@code ref.get()} into a field at construction has opted out of
+ * reload — which is sometimes right (see <em>deferred</em> below), but it must then be a deliberate
+ * choice rather than an accident of where the field was initialised.
+ *
+ * <h2>Not every key can change under a running daemon</h2>
+ * Keys fall into three classes, and the difference is about what already exists when the reload
+ * happens — not about how important the key is.
+ *
+ * <ul>
+ *   <li><strong>Hot</strong> — re-read per use, so a reload takes effect on the next spawn:
+ *       {@code fleet:} (every role pool, {@code charters}, and {@code tabLabel}),
+ *       {@code placement:}, and an existing profile's {@code weight} / {@code maxLoad}. Those
+ *       three are read through a supplier on {@code CompositePeerLauncher}, which is what makes
+ *       them hot — not the fact that they are config. <strong>This does NOT include
+ *       {@code fleet.leaders}</strong>: {@code Bridged.main} reads {@code cfg.fleet().leaders()}
+ *       once at startup to build the {@code LeadTabScanner} and the {@code LeadLauncher}, and
+ *       neither is reconstructed on reload — so a lead added, removed, or re-{@code tab}'d under
+ *       {@code fleet.leaders} needs a restart, the same as any deferred key below.</li>
+ *   <li><strong>Deferred</strong> — accepted into the new snapshot, but the wiring built at startup
+ *       keeps the old value until a restart: {@code lifecycle:}, {@code leadHeartbeat:},
+ *       {@code spawnReadyTimeoutMs} / {@code spawnReadyPollMs}, {@code quarantineCooldownSeconds}
+ *       (CB-578 stage B — baked once into the {@code BackendQuarantine} built at startup),
+ *       {@code guard:}, {@code worktreeRoot:}, adding or removing a profile (a new backend needs its own launcher,
+ *       which is constructed once), <em>and an existing profile's launch settings</em> —
+ *       {@code model}, {@code baseUrl}, {@code argv}, {@code env}, {@code mcpUrl},
+ *       {@code exhaustedPattern} (CB-578 stage A — compiled once into {@code Bridged.main}'s
+ *       pattern map at startup), and the rest. {@code credentialId} (CB-578 stage B) is NOT on
+ *       this list — it is read live off the config supplier at every quarantine check and
+ *       exhaustion event, exactly like {@code weight} / {@code maxLoad}, so it is hot instead.
+ *       {@code HerdrPeerLauncher} takes {@code Map.copyOf(profiles)} at construction and resolves
+ *       each spawn out of that copy, so those never reach a launch until the daemon restarts. A
+ *       reload logs these rather than pretending they applied.</li>
+ *   <li><strong>Cold</strong> — cannot change at all under a running daemon: {@code bind:},
+ *       {@code herdrSocket:}, {@code broker:} and {@code auth:}. The socket is bound, the broker
+ *       connection is open, and the auth mode decides who may reach the port that is already
+ *       listening.</li>
+ * </ul>
+ *
+ * <p><strong>A cold change refuses the whole reload.</strong> Not the hot half applied and the cold
+ * half warned about: that would leave the running daemon in a state matching no file on disk, which
+ * is the worst thing a reload can do to an operator debugging one. Refusing keeps the invariant that
+ * the live config is always some version of the file, and the message names the keys that must
+ * change through a restart.
+ *
+ * <p>A reload that fails to parse or fails validation is also refused, and the previous config keeps
+ * running. A config file being edited is normally read once mid-save; degrading a working daemon
+ * because it caught a half-written file would be a bad trade.

  *       become a lead by being placed — as a split, say — inside a matching tab.</li>
  *   <li>A worker cannot rename a tab: {@code tab.rename} is reachable only through
  *       {@link WorkspaceControl}, which no {@code bridge_*} tool exposes. The label is writable by
  *       the human at the terminal and by nobody the bridge is defending against.</li>
+ *   <li>The label is a <em>name</em>, not a capability. What a pane may do is decided by
+ *       {@code Authz} against the role {@code CallerResolver} returns; a tab that calls itself a
+ *       lead still cannot act as one unless the daemon's own registry agrees.</li>
  * </ol>
+ *
+ * <p><strong>CB-558 — bridged now writes lead labels too.</strong> This class used to be able to say
+ * that bridged never renames a lead tab, so the label was always the human's own writing and there
+ * was no round-trip from the daemon's rename back into its next decision.
+ * {@code dev.ltms.bridged.lead.LeadLauncher} ends that: an auto-launched lead is labelled by the

+ * real: a label left behind by a session that has since died would read as a live lead forever.
+ * This scanner does not solve that (its job is naming, and a stale name costs nothing here); the
+ * launcher does, by requiring a running agent in the tab before it counts the lead as live. If you

+ *
+ * <p><strong>A lead is not a member, and this class exists to keep it that way.</strong> Every other
+ * spawn path in the daemon goes through {@code HerdrPeerLauncher}, which does three things a lead
+ * must never receive:
+ * <ol>
+ *   <li>it appends the <em>reply charter</em> — "you are an off-subscription worker … end every turn
+ *       with {@code bridge_reply}". A lead is the orchestrator; telling it that it is a worker is
+ *       exactly backwards.</li>
+ *   <li>it registers the session with {@code SessionManager}, which subjects it to the idle reaper,
+ *       the context cap and the shutdown drain. An idle lead is the normal state of a lead, so the
+ *       reaper would kill the orchestrator for doing its job.</li>
+ *   <li>it can move a peer off the subscription via {@code ANTHROPIC_BASE_URL}. A lead stays on the
+ *       operator's subscription, always.</li>
+ * </ol>
+ * So this launcher talks to {@link AgentControl}/{@link WorkspaceControl} directly. The duplication
+ * with the member launchers (argv and env assembly) is deliberate and is the cheaper half of the
+ * trade: entangling the worker path with a not-a-worker case is how the three rules above get
+ * broken later, quietly.
+ *
+ * <p><strong>Liveness, and the label round-trip.</strong> {@code LeadTabScanner} used to be able to
+ * promise that bridged never writes a lead label. That is no longer true — an auto-launched lead is
+ * labelled by this class, and the scanner reads that label back. The risk this opens is not
+ * privilege escalation (the tab label never granted anything a pane could take for itself; see that
+ * class's javadoc), but <em>staleness</em>: a label left behind by a crashed session would otherwise
+ * read as a live lead forever, and the lead would never be relaunched. So a lead counts as live only
+ * when herdr also reports a <em>running agent</em> in that tab — see {@link #liveLeads}. A labelled
+ * tab with no agent in it is not a lead.

+/**
+ * The {@link PeerLauncher} the core actually holds when more than one adapter is configured — a thin
+ * router in front of one {@link HerdrPeerLauncher} per peer {@code kind} (Claude Code, opencode, …).
+ * It owns no transport of its own; it dispatches each SPI call to the delegate that owns the profile
+ * involved, and fans the fleet-wide queries (list/reap/caps/profiles) across all delegates.
+ *
+ * <p>Routing rules:
+ * <ul>
+ *   <li><strong>By profile</strong> — {@link #spawn}, {@link #effectiveCwd}, {@link #parityOverlay}
+ *       resolve the profile (a null/blank name → the global {@link #defaultProfile}) and delegate to
+ *       the single adapter that declares it. Profiles partition cleanly across adapters: the
+ *       constructor rejects a name claimed by two.</li>
+ *   <li><strong>By pane id</strong> — {@link #stop} routes to the adapter that spawned that pane
+ *       (recorded at spawn time). A pane the composite never spawned (only real for a caller that
+ *       hand-rolls an id) falls back to the first delegate; teardown is pane-id addressed and
+ *       tab cleanup is single-occupant guarded, so it is safe either way.</li>
+ *   <li><strong>Fleet-wide</strong> — {@link #reapOrphanWorkers} and {@link #capabilities} fan out
+ *       and combine. {@link #list} is deduplicated by pane id because every herdr-backed delegate
+ *       shares one herdr connection and so reports the same global agent set.</li>
+ * </ul>
+ *
+ * <p>CB-518: an unqualified spawn is routed through a {@link PlacementPolicy}. The default
+ * {@code fixed} policy reproduces the historical default-profile behaviour; {@code weighted} uses
+ * smooth weighted round-robin with {@code maxLoad} gating. If a chosen profile fails with
+ * {@link PeerUnreachableException}, the composite advances to the next available candidate and
+ * retries, bounded by the number of candidates.

+/**
+ * CB-551: an opt-in heartbeat that nudges the single idle lead back to work once it has been
+ * continuously idle past a quiet period with no open {@code bridge_send} driving it.
+ *
+ * <p>Why this exists: the fleet is ONE lead + architects + workers, so an idle, stalled lead is a
+ * single point of failure for the fleet's progress. {@link ReplyPushLoop} nudges the lead only when
+ * a worker reply lands; this loop is the timer that catches the gap where nothing lands and the
+ * lead simply sits idle with nobody to prompt it onward.
+ *
+ * <p>Mechanism mirrors {@link ReplyPushLoop}: a pure, unit-testable decision function
+ * ({@link #decide(long, Long, int, AgentStatus, boolean, boolean, FleetState)}) plus a thin
+ * scheduler around it. The loop is <em>entirely opt-in</em> ({@code leadHeartbeat:} in config); with
+ * no such block it is never constructed, so upgrading the daemon cannot silently acquire a behaviour
+ * that spends the operator's model subscription on its own initiative (constraint 1).
+ *
+ * <p>Four invariants keep it from becoming a runaway subscription burner:
+ * <ol>
+ *   <li><b>Status-gated</b> — a {@code WORKING} lead is making progress and is never touched; only an
+ *       injectable (idle/done/blocked) lead is even considered (constraint 2).</li>

+     *
+     * <ul>
+     *   <li>{@code InMemoryReplyInbox} — the ack only drops an entry from a local map. The messages
+     *       are already in the returned list, so nothing can be lost after this point.
+     *   <li>{@code AmqpReplyInbox} — the ack is a broker-side {@code basicAck}. Once it lands the
+     *       broker has forgotten the message. If the daemon dies while writing the response, the
+     *       reply is gone from the broker <em>and</em> the client never received it. Re-polling
+     *       cannot recover it, because there is nothing left to re-deliver.
+     * </ul>
+     *
+     * <p>So the loss window is the response write, and it is a genuine loss rather than a
+     * redelivery. This is accepted, not overlooked: the alternative — ack on the next poll — turns
+     * every normal drain into a double delivery, which costs more than the window it closes. A
+     * caller that needs certainty re-polls; that is idempotent for every case except this one.

- * Mechanism (b) of CB-307: a dedicated, status-gated push loop that nudges the primary's own
- * herdr pane when a worker reply lands with no live {@code bridge_send} to resolve it.
+ * A status-gated push loop that nudges a lead's own herdr pane when it has uncollected work
+ * waiting: a worker reply queued with no live {@code bridge_send} to resolve it (CB-307), or an
+ * async delegation ticket ({@code bridge_send(wait:false)}) that reached a terminal phase
+ * (CB-588).
  *
- * <p>The loop is triggered by {@link #onReplyQueued(String)} (called from
- * {@link MessageService#reply} after the durable inbox publish). It checks four conditions
- * at each tick via {@link #decide(String, int)}, then either injects a drain nudge,
- * waits for the primary to become injectable, or stops reminding.
+ * <p><strong>CB-590: one schedule per lead.</strong> Both kinds of work are triggered through
+ * their own entry point — {@link #onReplyQueued(String)} and
+ * {@link #onTicketTerminal(String, String, boolean)} — but both resolve the lead that should be
+ * nudged and coalesce onto a single per-lead reminder schedule, tracked in {@link #activeLeads}.
+ * Earlier this was two independent schedules (one keyed by worker target for replies, one keyed
+ * by lead for tickets) that could both decide to inject into the same pane in the same window —
+ * a race, not routine behaviour, but the expensive kind: it interrupts the lead's live turn
+ * twice. Collapsing to one schedule per lead makes that structurally impossible: at most one
+ * scheduled tick chain is ever live for a given lead (guarded by {@link #activeLeads}'
+ * compare-and-set), so at most one {@code agents.send} to that lead's pane is ever in flight.
  *
- * <p>Bounded: at most {@link #maxReminders} nudges per target, with a configurable backoff
- * between them. The reply is never lost — the durable inbox is the backstop.
+ * <p>Each tick examines <em>everything</em> pending for that lead — reply targets whose inbox
+ * still holds an unacked message ({@link #pendingReplies}) and tickets not yet collected
+ * ({@link #pendingTickets}) — and sends at most one combined nudge per tick
+ * ({@link #injectNudge(String, int, int)}). Work that arrives while the lead is busy is never
+ * lost: it is re-read fresh on every tick until the lead is injectable or its own reminder cap
+ * ({@link #maxReminders}) is reached — reply and ticket work each spend from their own budget, so
+ * one source exhausting its cap does not stop nudges about the other (post-CB-590 regression fix;
+ * see {@link #decide}) — whichever the durable inbox / pending-ticket set doesn't already answer
+ * via {@code STOP}.

-/**
- * The {@link PeerLauncher} the core actually holds when more than one adapter is configured — a thin
- * router in front of one {@link HerdrPeerLauncher} per peer {@code kind} (Claude Code, opencode, …).
- * It owns no transport of its own; it dispatches each SPI call to the delegate that owns the profile
- * involved, and fans the fleet-wide queries (list/reap/caps/profiles) across all delegates.
- *
- * <p>Routing rules:
- * <ul>
- *   <li><strong>By profile</strong> — {@link #spawn}, {@link #effectiveCwd}, {@link #parityOverlay}
- *       resolve the profile (a null/blank name → the global {@link #defaultProfile}) and delegate to
- *       the single adapter that declares it. Profiles partition cleanly across adapters: the
- *       constructor rejects a name claimed by two.</li>
- *   <li><strong>By pane id</strong> — {@link #stop} routes to the adapter that spawned that pane
- *       (recorded at spawn time). A pane the composite never spawned (only real for a caller that
- *       hand-rolls an id) falls back to the first delegate; teardown is pane-id addressed and
- *       tab cleanup is single-occupant guarded, so it is safe either way.</li>
- *   <li><strong>Fleet-wide</strong> — {@link #reapOrphanWorkers} and {@link #capabilities} fan out
- *       and combine. {@link #list} is deduplicated by pane id because every herdr-backed delegate
- *       shares one herdr connection and so reports the same global agent set.</li>
- * </ul>
- *
- * <p>CB-518: an unqualified spawn is routed through a {@link PlacementPolicy}. The default
- * {@code fixed} policy reproduces the historical default-profile behaviour; {@code weighted} uses
- * smooth weighted round-robin with {@code maxLoad} gating. If a chosen profile fails with
- * {@link PeerUnreachableException}, the composite advances to the next available candidate and
- * retries, bounded by the number of candidates.
