Adds the harness plug-in kind (interface 1). packages/plugins/harness/pi
and claude-code hold what core branched on: the adapter, thinking levels,
preflight, version probe, sandbox mounts, builtins line, typed tool names,
gate timeout, bundle files, adapter env, turn end and session-files path.
Core reaches a module only through the loader.
A session's route is the instance's harness, model and thinking vars, or
the three fallback. vars; a missing one refuses no-route, and the system
file's execution keys are never read for a session. The launcher checks
the primary route, then the fallback: harness-off, harness-refused,
thinking-unsupported, then preflight. A failed preflight falls back when
a fallback is set, and any refusal of the fallback names the primary's
failure too. Account checks run
only when the route's module counts an account. The manifest records
route, routeReason and harnessVersion, replacing piVersion and
claudeVersion. pi gets --thinking, Claude Code --effort, both from
MOSAIC_THINKING.
The business file refuses a partial fallback. routes and routes.set are
human-only bus verbs outside ORGANIZATION_KEYS; checkRoutes is shared by
routes.set, instances.set and limits.set and checks only changed routes.
The chief of staff changes an instance's model, and the assistant's whole
vars (Q169), through limits.set, so its route write runs the same checks.
A model outside launch.models refuses unknown-model, primary or fallback,
and routes.set passes that code through.
A new run binds only on a switched-on harness module name and records
its transcript path, which the usage reader uses. Settings gains a
Routing table with six selects per instance and loses the Role models
fieldset; it posts changed rows to /api/routes. webui/src/bus.mjs is
unchanged.
Until Jason's `mosaic plugins set` adds "harness": ["claude-code"], a new
launch refuses harness-off.
Dewey's row 146 work (agents/dewey/work/queue-146/build.patch, packet
08e327bf5), applied unchanged on 625c21f41. Candidate manifest
616f953f...9607 on dda7e31b0; no commit since touches its 10 paths.
Dewey's gate passed and 17 of 17 mutants were killed. Filbert approved
round 1 in comment 28641.

packages/cli adds mosaic inbox, decide, tasks, agents and trail over the
human-cli transport, and mosaic bus start, stop and status as the trusted
host (unit mosaic-bus@<business>, scripts/bus-service.sh). The host boots
packages/bus/src/process.mjs, passes config.trackers from the tracker.*
variables (lead decision 70), and runs a notifier child. The notifier DMs
each open blocking decision once and sends an 08:00 America/Chicago
digest, journaled in notify/<business>/sent.jsonl at 0600 with no Discord
ids. A torn journal tail is copied aside and truncated; a malformed line,
a directory looser than 0700 or a symlinked journal refuses (lead
decision 71). packages/discord gains dmRecipient, createDm and notify.mjs.
Candidate agents/rocko/work/slice1-s4, base b9b6cf00, build.patch
b52f7d68, manifest e858504e (29 files). Darkwing approved round 2 on
#1521 (comment 26855), Filbert approved round 2 (comment 26856). The
packet's mutant table lists M28 as killed; it survived, and BUILD-LOG
records the correction.
Integration gate in a worktree on 2557e29d with the patch applied:
bus 67, business 60, cli 49, control-board 124, discord 178, ledger 78,
mosaic 69, queue 148, seat 19, tasks 51 and webui 14, all with no
failures. Conversation is 149/3, the same K1, K3 and K10 cases that fail
on the base; S4 doesn't touch the package. Every scripts/test-*.sh is
green, with test-release 14/14 and test-task 98/98 on the existing gate2
compose network. A scratch test, not in this commit, booted the real
host with trackers against S3's fake Vikunja: the adapter went ready and
a task.close on a missing task answered task-not-found after a Vikunja
read.
