* feat(ci): weekly Codex sweep for date-carrying to-dos
Mondays 06:23 UTC (plus default-branch-only manual dispatch with
dry_run): a deterministic prefilter collects candidate lines where
to-do markers co-occur with date tokens, plus every deprecated compat
record from the plugin registry; a pinned openai/codex-action step
judges each candidate in context (genuine dated commitment vs
historical date or fixture) and writes an OVERDUE / DUE-30-days /
FUTURE report; a separate privileged job validates the report (tracked
file:line locations, date shape, inert text) and upserts one
marker-tagged tracking issue via the Barnacle app token, commenting
only when items newly become due.
The app token is minted on a fresh runner and checkout — never beside
Codex or its child processes; only the validated report artifact
crosses jobs. No permission-* subsets on token minting (installations
reject explicit subsets; see pr-ci-sweeper).
* chore(ci): localize upsert helpers with no external consumers
