Add a weekly Cron Trigger that fires at 17:00 America/Chicago (Central) every
Friday year-round, correct across the CST/CDT DST transition, and on fire lists
the pending reports (#10 Manager.ListPending) and hands their ids to the publish
step.
Cloudflare crons are UTC-only, and 17:00 Central is 22:00 UTC under CDT (summer)
and 23:00 UTC under CST (winter), so no single UTC cron expresses it. Register
BOTH Friday UTC hours in wrangler.jsonc (`0 22 * * 5` and `0 23 * * 5`) and gate
each fire: only the fire that is actually 17:00 Central does the work, so
publishing runs exactly once per Friday.
TinyGo/Wasm may lack the IANA tz database, so the gate does not call
time.LoadLocation. Instead internal/schedule computes the US Central DST rule
from first principles (CDT from the 2nd Sunday of March 02:00 to the 1st Sunday
of November 02:00, else CST) behind a pure func IsFriday1700Central(time.Time),
host-testable without TinyGo and cross-checked against the real America/Chicago
zone (via a test-only time/tzdata import) over a 20-year sweep.
- internal/schedule: pure DST gate + Run orchestrator; Publisher/PendingLister
seams; LogPublisher no-op default (the seam #14 replaces).
- worker/scheduled_wasm.go: js/wasm-only adapter registering the scheduled task
via init()+cron.ScheduleTaskNonBlock, wiring the R2-backed lifecycle Manager to
schedule.Run. worker/main.go is untouched.
- wrangler.jsonc: add triggers.crons (only the triggers section changed).
