* docs(timezone): add scheduling/viewing timezone architecture RFC
* feat(db): replace daily rollups with task_usage_hourly, add user.timezone
Migrations 100-104: add "user".timezone (Viewing tz), build the UTC
hourly task_usage_hourly rollup with its pipeline, drop the legacy
task_usage_daily / task_usage_dashboard_daily pipelines, and drop the
agent_runtime.timezone column. Report queries now slice day boundaries
at read time by the caller-supplied @tz instead of materialising in a
fixed tz. Regenerate sqlc.
* feat(server): add task_usage_hourly backfill command
Replace the two legacy backfill commands (daily / dashboard_daily) with
a single backfill_task_usage_hourly that loads historical task_usage
into the new UTC hourly rollup, sliced per workspace.
* refactor(server): resolve viewing timezone in report handlers
Report handlers resolve the Viewing tz per request (?tz query param,
then user.timezone, then UTC) and pass it to the hourly-rollup queries.
Drop the UseDailyRollup feature flags and the old raw-scan/daily-rollup
dual paths, remove the /api/usage endpoints, and stop the daemon from
reporting and the runtime handler from accepting host timezone.
* refactor(core): switch report queries to viewing timezone
API client and dashboard/runtime queries send ?tz with each report
request, the user schema/types carry the new timezone field, and the
runtime timezone field/mutation is removed.
* feat(views): add viewing timezone preference and UI
Add the useViewingTimezone hook and a Timezone setting in Preferences;
report charts and the dashboard week boundary follow the viewer tz.
Remove the runtime detail timezone editor and its locale strings.
* fix(test): update fixtures and stabilize tests for timezone refactor
The timezone architecture refactor changed several types without
updating dependent test code:
- RuntimeDevice no longer has a timezone field — drop it from the
create-agent-dialog runtime fixture.
- User now requires a timezone field — add it to the apps/web mockUser
fixture.
- The PreferencesTab timezone tests asserted on the async save handler
(PATCH then store update) with a bare expect, racing the mutation's
settle callback, and timed out querying the Select's ~600-option IANA
list on a loaded CI runner. Wrap the assertions in waitFor and extend
the timeout for those three tests.
* docs(timezone): document self-host migration order and trigger invariant
Add a SELF-HOST UPGRADE ORDER runbook to the backfill command's package
comment: applying migrations 100-104 in a single migrate-up drops the
legacy daily rollups before the hourly backfill runs, leaving dashboards
empty until cron catches up.
Add an INVARIANT comment on trg_atq_dirty_hourly noting that agent_id
must be added to the trigger's OF list if it ever becomes mutable,
otherwise dirty buckets for the old agent_id are silently missed.
* style(runtimes): drop trailing blank line in runtime-detail
