/api/time-conditions (company time zone by default, ranges validated,
unique override digit, never pointing at itself) with a live status
("open/closed/holiday now", same logic as the dialplan, shared), and
POST /:id/override, which writes PostgreSQL then AstDB SP/TCOVR.
/api/holidays CRUD plus import-us-federal (observed dates, computed in
code, skips days already listed). services/astdb.ts resyncs AstDB on
every AMI connect (PostgreSQL wins); services/toggles.ts applies
SpToggle TCOVR from *31N/*32N/*33N.
Generator: sp-tc-{id} per 03 §6.10 (override, holidays within the next
year, ranges rendered a minute short because GotoIfTime's end is
inclusive), sp-tc-override with a no-service fallback, admin-only
*3[123]X in sp-featurecodes, destApp time_condition. The date changing
in the company time zone triggers a forced apply so holidays roll over.
Golden cases holidays and ivr-business-hours.
Office hours page: click-and-drag half-hour grid plus an exact range
list, destinations, holiday destination, override key, status chip with
Force open / Force closed / Automatic; Holidays tab with the US federal
import. e2e m6-t4 found two bugs (pointer capture release throwing,
drawer overflow) and checks routing, AstDB, *321/*331 from an admin
phone, refusal for others, and the import reaching the dialplan.
