Ruling 1: model records keep a bounded previous list (64 ids, oldest dropped)
of ids that left by rotation, grace expiry or re-issue; a fire removes the
record. A tokens.keys leaf matches and counts every id in the lineage that
holds it. Lineage ids are unique host-wide. An orphaned leaf limits nothing,
logs one value-free line when it becomes orphaned, and the Console usage
view lists it.
Ruling 2: an agent with no model key under a key quota refuses
key-quota-no-model-key, passed through the broker, launcher and stop reason.
Ruling 3: covered by the lineage; no mayLaunch change.
Ruling 4: the usage module receives a frozen { readUsageQueue } only.
Ruling 5: every telemetry fixture wait races a 5 s real-timer deadline.
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.
The business file can name the account claude-code launches use,
`launch.account` = {name, credential}. `name` is an identifier and
`credential` names one login set's environment variables, never a value.
`launch.limits.tokens.daily.<account>` = {limit, since, reset, timeZone}
sets a daily quota for that account. A daily key that isn't the account's
name refuses the business read.
The new plug-in limit-check/daily-quota (interface 2, pure) starts a day at
the first instant at or after `reset` on that local date in `timeZone`. Across
DST that makes a 23- or 25-hour day, and a reset in a skipped hour starts at
the gap's end. It counts the account's known records of all four kinds since
the later of the day start and `since`, and counts unknown turns apart.
The launcher refuses account-credential-missing, account-credential-ambiguous
and account-is-credential (an account name equal to a session credential's
value). Messages name variables, never values. The account rides mayLaunch,
bindLaunch, the usage records, mustStop and the launch record. A pi launch
has no account, records NULL, and no daily quota covers it. `mosaic limits`
and the Console's Settings show one fixed line when a daily row shows:
"Daily quotas count only this stack's own use of the account, not its use
anywhere else."
Bus schema 3h to 3i: 3h reserved usage_records.account as
CHECK (account IS NULL). The new step 3h-3i.sql rebuilds the table in one
transaction, keeping every row's seq and the sqlite_sequence value, and
recreates the three append-only triggers. All of sqlite_master equals 3h's
apart from the account line. A 3h engine refuses a 3i store.
packages/bus/tests/account-migration.test.mjs covers all three, with a
step that fails partway and leaves 3h intact. 3i goes live only through
`stack-release.sh activate ... --migrate` with Jason present (P19 371); the
activate path takes the pre-migrate backup, and the way back is restoring
it (agents/dewey/work/queue-126/MIGRATION.md).
Mos's go mos-0835, six conditions: (1) one transaction, account-migration
test 2 and mutant D29; (2) sqlite_master against 3h, test 1 and mutant D28;
(3) account is never a credential, the launcher's account-is-credential
refusal (launch-account.test.mjs) and the business name pattern
(token-limit-settings.test.mjs); (4) MIGRATION.md, accepted by Mos in
mos-0837; (5) the packet's DESIGN.md "no schema change" line corrected;
(6) the public/ digest below.
The public/ change in bus.js (the daily line under the token-limit table)
carries Mos's decision 123 go mos-0833 on the +/- digest 03e6d9da...ba78,
unchanged at landing.
Owner Dewey, brief docs/plans/2026-10-14_prd-1.2-build.md, "Daily quota for
the credential the stack uses today". Review round 2 rebases the round 4
build onto 1df04f52f (row 167). Reviewer: Filbert approve 29068 on round 1
(manifest d18314f7...8e65); Filbert approve 29080 on
round 2 (manifest f332db76...6fa6).
Seat run on round 2: touched 158/0, singles 1388/0 with 1 esbuild skip,
test-land-work.sh 86/0, 30/30 mutants killed.
Sage gate on 54319f552: GATE_PASSED, 2474+422/0, all 15 packages, the queue
suite and 10 script selftests.
Nothing live.
Adds token limits under launch.limits.tokens (instances, providers, keys,
models.P.M). Core (packages/bus/src/limits.mjs) reads the organization
file and the per-turn usage records row 124 writes, then asks every
switched-on limit-check plug-in; the first refusal wins. A limit no
switched-on check reports reads "not enforced". The limit-check kind is
interface 2 (mayLaunch, mustStop, report); a v1 check is refused at load.
The shipped token-limit check is pure and counts known end records only;
unknown turns add nothing and are shown as their own count.
The launcher refuses limit-reached through the host's mayLaunch op, or
limit-check-failed naming the check. The broker asks mustStop after a
usage end and stops the run at its next receive or state. Settings stamps
since on a new or changed limit and runs reset; launch.mjs and
business.mjs validate the shape. Readers: mosaic limits and mosaic limits
reset, the bus limits view, the Console /api/bus/limits route and the
Settings token table with Reset. Key limits stay "not enforced" until
row 126 names accounts on records.
Owner Dewey, design under lead decision 150.
Reviewer Filbert: r1 changes (comment 28965), r2 approve (28981), r3
approve (28996) on candidate manifest 8b71c405...fe56 after the rebase
onto row 164 (37 of 38 paths with identical +/- lines, TOOLS.md:621
bracket). Decision 123 go on the bus.js hunk from Mos (mos-0814). Sage
gate on b6827d19e: 25 steps, all rc 0 (15 packages, 10 script suites), 2295 node tests and 422 script selftests, 0 failed, 20:03:25Z to 20:08:08Z, network sage-r125_default removed.
Live stays as pinned. Not part of the 8e7ea89a1 window.
