The old picker was a row of 5 frequency pills (One-off / Daily / Weekly /
Monthly / Yearly) followed by a separate detail panel — common cases
needed several clicks (interval, weekday list, etc.) and the visual
hierarchy didn't show what was selected at a glance.
New design — a vertical radio list with seven first-fire-aware presets
plus a Custom… expander:
○ Don't repeat (one-off)
○ Every day
○ Every weekday (Mon – Fri)
○ Every weekend (Sat – Sun)
○ Every week on Wed (matches start)
○ Every month on day 13 (matches start)
○ Every year on May 13 (matches start)
○ Custom… ▼ expands
Custom… reveals the existing power-user controls (frequency dropdown,
interval input, weekday picker, day-of-month, end-condition) without
crowding the common path. Toggling between presets and custom is
lossless — the spec is the source of truth.
New helpers in `lib/recurrence.ts`:
- `presetToSpec(id, firstFire)` — canonical RecurrenceSpec for each
preset (round-trippable).
- `matchPreset(spec, firstFire)` — reverse mapping; returns "custom"
for anything that doesn't fit a shortcut, so the picker auto-flips
into expanded mode for non-preset specs.
- `presetDescriptors(firstFire)` — list of preset id/label/hint with
first-fire-aware copy ("Every week on Wed", "May 13", etc).
Wired into both:
- reminder-wizard/when-form-client.tsx (creating)
- reminder-edit/edit-when-form.tsx (editing a section in place)
Tests (+4, 134 web + 26 bot = 160 total green):
- recurrence.test.ts gains a "preset shortcuts" suite covering:
* presetToSpec → canonical spec for each id
* round-trip via matchPreset
* matchPreset returns "custom" for non-shortcut specs
(interval > 1, weekly Mon/Wed/Fri, end=after, monthly on a
different day-of-month than the first fire)
* presetDescriptors labels are first-fire-aware
