Review "changes 8" fix round for org-redact6.
- launcher: a harness module's throw names its system code or class,
never its message; preflight, loader, bundle, checkout, sandbox and
route text is relayed with host paths replaced (relay()).
- claude-code and pi preflights name MOSAIC_CLAUDE_BIN and the
repository's node_modules, never a path; persona and skill bundle
errors and sandboxProblem name their file or the sandbox by label.
- seat session: thread store, legacy store, overlap, busy lock and
newRun refusals name the place under the data root.
- discord: unknown keys, binding names and turn ids are described when
not plain; approvals, journal and repository read errors name the file
and code; git drops stderr lines that carry a host path and a spawn
failure names its code only.
- seat, control-board: registration fields and seen keys are described
when not plain; invalid seat name and layout state the constraint.
- organization: the registry names the config directory and registry
file by label; --project is quoted only when it is a plain name;
systemConfigProblem moves to its own module.
- scripts/mosaic-config.mjs: the config by where it came from, the data
root and its marker by role, keys and arguments only when plain, and
error codes in place of raw messages. Exit codes unchanged.
- webui sso-config: an unknown console key is named only when plain.
Sentinel tests in each package's path-redaction-labels file fail on
BASE; pins that quoted a path now assert the label and its absence.
The cli tests that launch pi deleted only the session login names, so pi's
preflight passed or refused by whatever provider keys the host exported. A
shared helper now deletes every credential pi's preflight reads and gives pi
launches one made-up key. The refusal itself is unchanged.
pi bundle() takes a default argument again, so a call with none returns the
non-proxy bundle, as before P3. pi.bundle leaves out a launch.models entry
whose provider has no proxy route instead of failing every pi launch (F2);
malformed proxy entries still refuse. The invalid session proxy context
BundleError gets the code invalid-proxy-context. New tests cover F2, the code,
and the three proxy account branches in the launcher (F3).
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.
