fleetd/bridged/bridged.example.yaml

# bridged configuration (example). Copy to bridged.yaml and adjust.
#
# bridged is the sole gateway between primary/worker Claude sessions and herdr.
# It is NOT a Claude process and must never carry ANTHROPIC_BASE_URL.

# REST + MCP listen address. Keep it on loopback unless you also switch auth.mode to `token`
# below — bridged REFUSES TO START on a non-loopback bind under loopback-trust (see auth).
bind:
  host: 127.0.0.1
  port: 8765

# API authentication (CB-501). Governs how a caller that is NOT an on-host worker pane proves it
# is the primary. Worker identity never depends on this: a loopback peer PID that maps to a herdr
# pane is unforgeable and is always honoured, so turning auth on cannot lock the fleet out.
#
#   mode: loopback-trust  → DEFAULT, and the historical behaviour: any loopback caller that is not
#                           a worker is the primary, no credential needed. Sound ONLY because the
#                           OS refuses remote connections to a loopback socket.
#   mode: token           → such a caller must send `Authorization: Bearer <token>`; without it it
#                           is anonymous and authorized for nothing. REQUIRED for a non-loopback
#                           bind — the daemon fails fast otherwise, because "unauthenticated ⇒
#                           primary" on a reachable port would hand spawn/stop/send to anyone.
#   tokenEnv              → host env var holding the token (never the literal value). Default
#                           BRIDGED_API_TOKEN. Read only in token mode; empty ⇒ startup fails.
#
# TLS is deliberately NOT terminated in the daemon (CB-501 D3): run a reverse proxy in front and
# let it own certificate lifecycle, e.g.
#     location / { proxy_pass http://127.0.0.1:8765; proxy_set_header Authorization $http_authorization; }
# The broker link gets TLS from its own URI (amqps://…) — see `broker` below.
# auth:
#   mode: token
#   tokenEnv: BRIDGED_API_TOKEN

# Optional pinned primary terminal (CB-307). Names the herdr pane the PRIMARY itself runs in:
# a caller whose connection maps to this pane resolves as the primary (no credential needed —
# the pane mapping is as unforgeable as a worker's), and reply nudges are pushed to it.
# REQUIRED when the primary runs inside a herdr pane — without it the pane match reads the
# primary as a worker and refuses spawn/send/stop. Get the id from bridge_whoami; re-pin if
# the primary moves panes.
# primary:
#   terminal: term_0123456789abcd
#   pushReminders: 5      # max nudges before giving up (default 5)
#   pushBackoffMs: 15000  # delay between nudges (default 15000)

# CB-530: MORE THAN ONE LEAD. `primary:` above is singular by construction — every other pane
# resolves as a worker — which is right for one lead driving a fleet and wrong the moment two leads
# (say a Claude lead and an opencode lead) work as peers: the second is silently demoted and refused
# every orchestration call. List each lead's pane here and all of them resolve as leads.
#
#   terminal → the ONLY field identity depends on; get it from that session's bridge_whoami
#   kind/model → descriptive; they document what runs in the pane and are echoed by bridge_whoami
#
# A lead is never spawned — it pre-exists, which is exactly why it must be named rather than created.
# `bridge_whoami` reports `{"role":"primary","leader":"<name>"}`; role stays "primary" because a lead
# IS a primary for authorization, so nothing that keys on the role breaks.
#
# KEEP `primary:` when adding leads: it still addresses the CB-307 push loop, which needs a single
# destination for its nudges. If both name the same terminal, the `fleet.leaders:` entry wins.
#
# Leads are configured under `fleet.leaders:` — see THE FLEET further down.
#
# Two things stop the tab-name convention from becoming a way to claim leadership: the configured
# member spaces are excluded from the scan, so nothing bridged places can land in a matching tab;
# and startup REFUSES a `tabPrefix` that the fleet tabLabel template, or any per-profile `tabLabel`
# override, also matches — so the two namespaces cannot overlap by accident. The label is a NAME,
# never a capability: what a pane may do is decided by the role the daemon resolves for it.

# CB-551: IDLE-LEAD HEARTBEAT — nudge the single lead back to work when it has been continuously
# idle (no open bridge_send driving it) past the quiet period. The fleet is one lead + architects +
# workers, so a lead that stalls is a single point of failure; the ReplyPushLoop only nudges when a
# reply lands, and this timer catches the gap where nothing lands and the lead just sits idle.
#
# Opt-in on purpose — it SPENDS the operator's subscription on its own initiative (each nudge starts
# a lead turn nobody asked for), so upgrading the daemon must never switch it on for you. Absent
# block = feature off, exactly as before.
#
# Three knobs, each with a default that errs on the side of not burning context:
#   idleAfterSeconds: 300   # how long the lead must stay idle before the FIRST nudge (default 300 —
#                           # absorbs normal post-turn pauses; re-prompting every pause burns context)
#   backoffMs: 60000        # re-check cadence / spacing between nudges past the quiet period (default 60000)
#   quietNudgeCap: 3        # cap on consecutive nudges that find NOTHING pending, then it stops
#                           # until real state appears (default 3 — never nag an empty fleet forever)
# leadHeartbeat:
#   idleAfterSeconds: 300
#   backoffMs: 60000
#   quietNudgeCap: 3

# herdr Unix socket. Omit to use the client default
# (${HERDR_SOCKET_PATH:-~/.config/herdr/herdr.sock}).
herdrSocket: ~/.config/herdr/herdr.sock

# How member sessions are spawned. Define one or more named profiles (backends) under
# `profiles`; each key is the profile name (also the ccs profile). A profile says only WHICH
# BACKEND — model, CLI adapter, credentials, cost. It says nothing about what a member spawned on
# it is for; that is the member's role, and roles live under `fleet:` below. Which profile an
# unqualified spawn lands on comes from that role's pool, not from a global default.
#
# Shared knobs (placement/workspace) can be repeated per profile; they usually match.
#   placement: tab   → each worker lands in its OWN tab in a dedicated worker space (default).
#                      Use `pane` for the legacy behaviour (split the focused tab).
#   mcpUrl           → bridged mounts the bridge MCP (--mcp-config, inline) + reply charter
#                      (--append-system-prompt) as launch flags; nothing is written to the profile.
#   tokenEnv         → host env var holding the worker's auth token (value never stored in config);
#                      omit for a backend that needs no token (e.g. a local ollama).
#   cwd              → pin this profile's working directory (CB-112). Omit to inherit the primary's
#                      cwd on an MCP spawn, else the daemon's cwd — never $HOME. See
#                      docs/Worker-Startup-and-Trust.md.
#   configDir        → CLAUDE_CONFIG_DIR for the worker, so it inherits that profile's
#                      skills/MCP/hooks. Omit to leave the worker on the host default.
#   parityOverlay    → repo-relative paths copied primary→worktree so a worker in a provisioned
#                      worktree sees the same local config (CB-301-ext). Omit for the default set:
#                      [.claude/settings.local.json, .env, .envrc].
#
#                      Do NOT add .mcp.json (CB-525). A worker's tools are whatever its launcher
#                      mounts — the bridge, and nothing else. Replicating the primary's MCP config
#                      handed a worker the primary's IDE servers, which are bound to the primary's
#                      checkout, so its navigation returned paths OUTSIDE its own worktree: one
#                      worker made all 59 of its edits in the primary tree while compiling its
#                      worktree, and every build it ran was of code that did not contain them.
#                      bridged neutralizes a provisioned worktree's .mcp.json for this reason;
#                      listing it here would copy the primary's back over that.
#   gitTokenEnv      → host env var holding the git-forge API token. When set, its value is injected
#                      as GITEA_TOKEN so the worker can open its OWN PR at checkpoint (CB-302).
#                      Opt-in by design — omit and the worker gets no PR-create grant (push over
#                      SSH is unaffected). The token value itself is never stored in this file.
#   gitHostEnv       → host env var holding the forge host (default GITEA_HOST). Injected as
#                      GITEA_HOST *only* alongside a resolved gitTokenEnv.
#   env              → extra environment for this profile's workers, as a literal key/value map
#                      (CB-511). Use it to give workers a toolchain.
#
#                      A worker's environment does NOT come from your shell. bridged hands herdr an
#                      explicit env map and herdr merges it into ITS OWN process env — so before
#                      CB-511 a worker inherited whatever PATH the herdr server happened to be
#                      started with, which on a long-lived herdr can predate your toolchain entirely
#                      and leave workers unable to run `mvn` or `java` at all.
#                      bridged now propagates ITS OWN PATH to every worker by default; set `env:`
#                      only to override that or add more (JAVA_HOME, …). Since the default is the
#                      daemon's PATH, make sure the daemon is started with a good one — see the PATH
#                      lines in deploy/dev.ltms.bridged.plist and deploy/bridged.service.
#
#                      Adapter-owned variables always win over `env:`: ANTHROPIC_BASE_URL and the
#                      rest of the ANTHROPIC_*/CLAUDE_* wiring are applied after it, so an `env:`
#                      entry cannot repoint a worker past the SubscriptionGuard — which is checked
#                      against `baseUrl` alone.
# Put `defaultMode: "auto"` in each ccs profile so the worker runs autonomously.

  # CB-508: point an opencode profile at your OWN OpenAI-compatible endpoint (local vLLM, llama.cpp,
  # LM Studio, TGI…) instead of opencode's gateway. Setting `baseUrl` on a `kind: opencode` profile
  # makes the bridge emit a custom `provider` block into the generated opencode.json — opencode has
  # no ANTHROPIC_BASE_URL seam, so this is how the endpoint is pinned.
  #   baseUrl → a bare host:port gets `/v1` appended (where these servers mount the API); a URL that
  #             already has a path is used verbatim, so a custom mount point still works.
  #   model   → MUST be "<provider>/<model>". The provider half names the generated block; the model
  #             half must match an id the server reports at /v1/models. One field drives both the
  #             declaration and the `-m` flag, so they cannot drift apart. A bare model name with a
  #             baseUrl set is rejected at spawn rather than silently using the default gateway.
  #   tokenEnv → optional; its value becomes the provider apiKey. Most local servers ignore the key,
  #             so a placeholder is used when unset (the AI SDK still requires a non-empty one).
  # NOTE: no `guard` entry is needed even with a baseUrl set. The SubscriptionGuard exists to stop a

  # credential path at all.

placement: weighted

# Re-read this file without restarting the daemon (CB-559). Off unless you add this block, so an
# upgraded bridged keeps the old behaviour: the file is read once at boot and never again.
#   enabled          → turn the watch on. bridged checks the file's modified time on a timer and
#                      reloads when it moves.
#   intervalSeconds  → how often to check (default 10). One `stat` per tick, so this is cheap.
#
# Not every key can move under a running daemon, and the difference is about what already exists
# when the reload happens — not about how important the key is:
#   HOT       → takes effect on the next spawn: the whole `fleet:` block (every role pool,
#               `charters`, and `tabLabel`), `placement:`, and an existing profile's weight / maxLoad. Those are
#               hot because the placement policy reads them through a supplier — being config is
#               not by itself enough to make a key hot.
#   DEFERRED  → accepted into the new config, but the wiring built at startup keeps the old value
#               until you restart: `lifecycle:`, `leadHeartbeat:`, `guard:`, `worktreeRoot:`,
#               `spawnReadyTimeoutMs` / `spawnReadyPollMs`, ADDING or REMOVING a profile (a new
#               backend needs its own launcher, and launchers are built once), AND an existing
#               profile's launch settings — model, baseUrl, argv, env, configDir, mcpUrl, tabLabel.
#               The launcher takes a copy of `profiles:` at startup and resolves every spawn out of
#               that copy, so those never reach a launch until you restart. The reload logs them by
#               name rather than pretending they applied.
#   COLD      → cannot change at all: `bind:`, `herdrSocket:`, `broker:` and `auth:`. The socket is
#               bound, the broker connection is open, and the auth mode decides who may reach the
#               port that is already listening.
#
# A changed COLD key refuses the WHOLE reload — not the hot half applied and the cold half warned
# about. A half-applied reload would leave the daemon matching no file on disk, which is the worst
# thing a reload can do to an operator debugging one. A file that fails to parse or fails a startup
# validator is refused the same way, and the running config stays live.

# THE FLEET (CB-557) — who the daemon may run, and under which role. This one block replaced four
# older keys: `leaders:`, `members:`, `leadScan:` and `defaultProfile:`.
#
# 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.
fleet:
  # Optional launch-charter text, keyed only by the singular role wire names: architect, dev,

  # is deliberately not supported.

      You are an architect in this fleet. You refine work before anyone builds it:
      scope, acceptance criteria, risks, and a unit split. You read the repo and
      write analysis. You never commit production code and never open a PR.
      A design task is worked by two architects. Design alone first, then exchange
      and say plainly where you disagree. Do not concede just to agree.
    dev: |-
      You implement the one unit you were given, and nothing else. You test it,
      commit it, and open your own pull request. You never merge.
    reviewer: |-
      You review the diff you were given. You report bugs, risks and missing tests.
      You do not change code.

  # Optional. Template for a member tab's label; {role}, {profile}, {model} and {n} are substituted.
  # {n} counts per role+profile, so `dev: sonnet #2` really is the second sonnet dev. Because {role}
  # comes from a closed enum, a generated label can never begin with a lead's tabPrefix.
  # tabLabel: "{role}: {profile} #{n}"

  # Panes that orchestrate rather than are orchestrated. A lead may now be CREATED as well as
  # recognised: give it a `profile:` and the daemon launches the shortfall when fewer than
  # `instances` are live. Give it only a `terminal:` and it is recognise-only, as before.
  #
  # `tabPrefix` is the naming convention that finds a lead without pasting a terminal id: label the
  # tab `lead: <name>` when you open it and the pane is recognised on the next rescan. Reopen the
  # tab later and the id changes; the label does not.
  #
  # A lead the daemon launches is labelled BY the daemon, using the same convention, so it is found
  # by the same scan. A lead counts as live only when herdr also reports a running agent in that
  # tab — a label left behind by a session that died does not block the relaunch.
  #
  # An auto-launched lead is NOT a member: it gets no worker reply charter, is never registered with
  # the session lifecycle (the idle reaper would kill your orchestrator), and stays on the
  # subscription — ANTHROPIC_BASE_URL/AUTH_TOKEN are stripped from its env whatever the profile says.

# Spawn-readiness gate (CB-306). The launcher blocks until the worker's herdr status is
# injectable (IDLE/BLOCKED/DONE) or the timeout elapses. 0 disables the gate.
# NOTE: keys are camelCase — config is bound by plain Jackson with no naming strategy and
# unknown keys are ignored, so a snake_case key would be silently dropped (default kept).

# Worktree provisioning root (CB-301-ext). Where per-worker git worktrees are checked out so
# each worker owns an isolated branch instead of sharing the primary's tree. Omit to default
# to a sibling directory of the repo root.
# worktreeRoot: /Users/me/src/.bridged-worktrees

# Session lifecycle limits (CB-303). All knobs are opt-in; omit or set to null to keep
# the feature disabled. By default the daemon never reaps, caps, or drains sessions.
#   idleTtlSeconds     → reap READY/DONE sessions idle longer than this (never BUSY/SPAWNING)
#   contextCap         → force-release a session after this many delegated turns
#   drainTimeoutSeconds → seconds to wait for BUSY sessions on shutdown before forced teardown

# Durable reply delivery (CB-307 Stage 2). OMIT this block entirely to keep the default
# in-memory, soft-state reply inbox (late worker replies are held only until a daemon bounce).
# Set a broker uri to swap in the AMQP-backed inbox: worker replies with no open send are held
# on a durable per-target queue (agent.<target>.inbox) and survive a restart — the broker
# redelivers anything the primary had not yet drained. Production default is LavinMQ; a stock
# RabbitMQ speaks the same AMQP 0-9-1, so it is a URI-only swap.
#   uri → AMQP connection URI. No trailing slash ⇒ the default vhost "/"; an empty path ("/")
#         is vhost "" and will NOT connect. Encode a named vhost as .../%2Fmyvhost.

# Active push-to-primary (CB-307 Stage 3). When a worker reply lands with no open bridge_send,
# the ReplyPushLoop injects a *drain nudge* (never the payload) into the primary's own herdr
# pane — status-gated (only when injectable, never mid-turn) and bounded. Ack = drain: the loop
# stops as soon as the primary's inbox is empty.
#   terminal       → pin the primary's herdr terminal id. Omit to learn it from the connection on
#                    the first orchestration-side MCP call (the normal case). An off-host or
#                    non-herdr primary leaves this unresolved → the loop is a no-op and delivery
#                    degrades to pull; the reply is still never lost.
#
#                    REQUIRED (CB-522) if the primary itself runs inside a herdr pane. Caller
#                    identity resolves a loopback PID to its herdr pane, and PaneLocator scans
#                    EVERY pane — not just bridged-spawned ones — so such a primary is otherwise
#                    classified as a WORKER and refused SPAWN/SEND/STOP. That failure is
#                    self-locking: the learned terminal is populated by the very orchestration
#                    calls being refused, so only this pinned value can break the cycle. Read the
#                    id off bridge_whoami (it reports the current terminal even while
#                    misclassified) and re-pin whenever the primary moves panes.
#   pushReminders  → max nudges before giving up (default 5)
#   pushBackoffMs  → delay between nudges in ms (default 15000)
