Small if-then automation layer. Rules persist in SQLite; the runner
lives on the frontend and binds to the Phase 6 event bus so the rule
pipeline reuses the same delivery primitives (timer events, TTS,
Tasks navigation).
Storage:
- Migration v12 adds implementation_rules (id, enabled, trigger_kind,
trigger_value, actions_json, last_fired_key, created_at,
updated_at) with enabled+trigger_kind index for the runner's hot
path.
- CRUD helpers: insert / list / get / set-enabled / mark-fired /
delete, plus a round-trip test.
Commands (all main-window-guarded via ensure_main_window):
- list_implementation_rules
- create_implementation_rule — validates HH:MM, checks the target
task exists at save time for surface-task actions, caps
speak-line at 240 chars, pins v1 timers to 5 minutes.
- set_implementation_rule_enabled
- mark_implementation_rule_fired — main-thread idempotency shim so
the runner can atomically claim a fire.
- delete_implementation_rule
Runner (implementationIntentions.svelte.ts):
- Subscribes to kon:task-completed and kon:morning-triage-finished
(MorningTriageModal now emits on all three exit paths — empty,
skipped, picked — so skip counts as finishing).
- 30 s poll for time-of-day rules, plus an immediate check on startup
so a rule whose time has already passed today catches up once.
- Idempotency via last_fired_key composed as YYYY-MM-DD@HH:MM for
time rules; new time rules whose HH:MM has already passed today
are pre-seeded so they don't fire retroactively on save.
- Rules are paused when Nudges "Mute for now" is on — a hard mute
stops all rule delivery in addition to OS notifications.
- Stale-task safety: if a surface-task action's target has been
deleted, the runner opens Tasks and warns clearly rather than
pretending to surface something that's gone.
Editor (ImplementationRulesEditor.svelte):
- Lives in Settings under a new "If-then rules" accordion section.
- `If` picker: time of day (with time input), a task completes,
morning triage finishes.
- `Then` composer: optional surface (inbox / today / all tasks /
specific task), optional 5-min timer, optional speak-aloud line.
- Saved rules list with enable toggle + delete.
Rules table integration for Phase 10b rename sweep: add
implementation_rules to the kon.db → corbie.db migration shim when
that phase lands.
Gates: fmt, clippy -D warnings, cargo test 265/0, svelte-check
0/0, npm build green. Pre-existing Vite chunk warning on sounds.ts
is unrelated to Phase 7.
