serve --tester-port N starts a second listener on 127.0.0.1:N in the same
process, with a bus caller through TESTER_CLI. N is 1024..65535, not
--port and never 7332, and the flag needs the bus configured. The tester
listener takes only instances.set, routes.set and name.set; settings
save, project-file save, assistant stop, bus message and chat writes
refuse 403 with no bus call. It refuses the main listener's auth header,
and every other listener refuses any request carrying x-mosaic-tester.
/api/config answers tester: true and the page shows a tester banner with
the routes, instances and seat name editors only. tester-off and
tester-required map to 403 in a serve.mjs coreBusStatus wrapper, so
bus.mjs stays pinned (row 164).
The broker lets a tester read credentials (with #secretCheck), routes,
project.files and project.file; project.file.save stays human-only.
webui-service.sh takes --tester-port with serve's checks. stack-release
activate --tester-port N writes the flag to the pointer and the unit,
refuses tester-port-target when the target copy's Console lacks it, and
activate or rollback to such a copy drops the flag and says so in --plan.
docs/TOOLS.md rewords the stale row 175 two-phase step (#1673 F1).
Built by Rocko on 473258a51 (manifest a4c728fc...52c9), approved by Dewey
in round 2 (#1674 comment 29322) after round 1 changes (29309), Sage's
gate green on 473258a51 plus the patch in run 2. Run 1 failed T34's
failed-pm_launched subtest with capture-failed: activate and pm-on name
the activation by the second, so the two ran in one second and collided
on the rollback set. That race is row 169's (the base fails the same way
with the id pinned), and a follow-up row fixes it (Vikunja P19 391).
TESTER_VERBS gains usage, names, limits, plugins, instances, project.list,
thread.list, name.set and project.create. A tester reads limits, plugins
and instances and sends plugins.set, instances.set and routes.set, each
logged with actor tester. The project file verbs refuse a tester
tester-refused. The broker and CLI drop the [mos test]
prefix rule (mos-0872 Q1). The CLI takes --tester on the seven reads and
the W1-W7 write forms and refuses it (exit 4) elsewhere, bus start and
stop included.
project init --tester checks the project area, refuses the area root
itself, binds the tester with one agents read, then commits the layout as
tester (mos-0872 Q2). scripts/mosaic sends plugins, name, names, follow,
threads and thread to packages/cli (sage-1081). The row 164 pins are
untouched.
Built by Dewey on 9e74925c2 (three commits to 989699f7c, manifest
2e30f2a1...29d5f), approved by Filbert in round 3 (#1673 comment 29279),
Sage's gate green on 716ddcf1e plus the patch.
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.
A tester binds with a process proof from the bus's own tester-cli.mjs
when the business var bus.tester is true. It may send [mos test] messages
to a role, receive replies on the tester address and use the read verbs;
every other verb refuses. Messages store from_role tester and write no
human.input event. turnRequest() marks them as never Jason's instruction.
human.mjs is unchanged.
