Phase 02 Report — Cron Wiring

Files Modified/Created

• Created src/modules/validate-cron.js — validates { name, schedule, handler } entries; 5/6-field cron regex check
• Created src/modules/cron-dispatcher.js — dispatchScheduled(event, env, ctx, registry) fan-out with per-handler try/catch
• Modified src/modules/registry.js — added validateCron import; cron validation + duplicate-name check in loadModules; CronEntry[] collection in buildRegistry; registry.crons exposed in typedef and return value
• Modified src/bot.js — added getRegistry(env) export; shares same memoized registry with fetch handler
• Modified src/index.js — added scheduled(event, env, ctx) export; calls getRegistry then dispatchScheduled
• Modified wrangler.toml — added [triggers] crons = [] placeholder with authoring instructions
• Created tests/modules/validate-cron.test.js — 9 tests (valid entry, bad name, bad schedule, bad handler)
• Created tests/modules/cron-dispatcher.test.js — 6 tests (schedule match, no-match, fan-out, error isolation, ctx pass-through, empty registry)
• Modified tests/modules/registry.test.js — added 6 cron collection tests (empty, collect, fan-out, duplicate name, non-array, invalid entry)

Tests

• All 139 tests pass (14 passed files)
• 0 new lint errors introduced (17 eslint errors are pre-existing: KVNamespace/D1Database/Request undefined types + CRLF line-ending biome format noise from Windows git autocrlf)

Deviations

• getRegistry(env) added to bot.js rather than importing buildRegistry directly in index.js — avoids bypassing the Bot init path and ensures single shared memoized registry across fetch + scheduled.
• Test fixture module names use kebab-case (mod-a, mod-b) to satisfy createStore's ^[a-z0-9_-]+$ constraint (initial camelCase caused 2 failures, fixed immediately).

Status: DONE Summary: Cron Triggers wired end-to-end — module contract extended with crons[], dispatcher dispatches per schedule, registry collects + validates, scheduled() exported from worker entry. All tests green, no new lint issues.
