PRD 1.20 REQ-TASK-1, REQ-PLUG-1, REQ-WS-8. Each organization keeps its
tasks in its own bus through the new task-tracker plug-in kind. The
default module is the built-in store; Vikunja is the optional module
and a Vikunja organization keeps today's path.
- bus schema 3u to 3v (migration 3u-3v.sql): store_tasks, append-only,
one row per write, each citing its events row; seven guard triggers.
- broker: the eight role verbs on the store with the slice 1 field
table checked twice (module, then a before/after field diff); the
person's tasks.create/edit/archive/unarchive/delete as human.input
events; the tasks read returns store rows in board order (group,
position), filtered and paged like tracker rows.
- runtime: each business gets its module at start (organization file
plugin, else vikunja with a tracker entry, else store); a store
business with a Vikunja tracker refuses the boot (tracker-config).
- plugins: task-tracker kind with store and vikunja modules.
- cli: the launcher's tracker flag covers store organizations; trail
prints store writes.
- pins: schema.test counts, the bus migration tests, stack-release #811
and T46 (store_tasks on the always list; COUNTED unchanged),
budget-supervisor accepts 3v.
Rebased onto SYS1 by the lead: SYS1 took 3t-3u, so this step is 3u-3v.
Unify halt and fire cancellation by verified run identity with durable first-owner receipts and shared deadlines. Integrate the instance control with the current host, library and tester-socket paths. Focused nine-file evidence is 62 passing tests; broad suites, mutants and review remain pending.
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.
packages/tasks adds the Vikunja v2 client, the eight task verbs, the
board-plus-cursor poll with its 60 s window and the digest. The broker
gains the task verbs and boots trackers from the boot config (lead
decisions 66 to 68). Due dates are truncated to the second and recorded
as truncated (B1). A write that lands but whose final read fails counts
as landed, in update and in create (B2).
Candidate agents/darkwing/work/slice1-s3, build-r2.patch 71ce87e6,
manifest e10e30e3 (28 files). Filbert approved round 2 on #1520
(comment 26853). Darkwing's post-reset rerun: test-release 14/14,
test-task 98/98 (comment 26857).
Integration gate in a worktree on c4baf779 with the patch applied:
bus 67, business 60, control-board 124, discord 173, ledger 78,
mosaic 69, queue 148, seat 19, tasks 51 and webui 14, all with no
failures. Conversation is 149/3. The three cohort kill cases (K1, K3,
K10) fail the same on the unpatched base, and the patch doesn't touch
the package. Every scripts/test-*.sh is green. test-release 14/14 and
test-task 98/98 ran on the existing gate2 compose network, because the
host's Docker address pools are exhausted. No network was created or
pruned.
