## Implementation Plan
## Implementation complete (~617 new lines, 2450 total)
Full plan: `doc-17 - Implementation Plan: ML-176.2 — Presto splash screen, search views, and on-screen keyboard`
### State constants + globals
### Summary
- Renumbered STATE_MONTH=0, STATE_DAY=1, STATE_RECORD=2. Added STATE_HOME=3, STATE_SEARCH_INPUT=4, STATE_SEARCH_RESULTS=5. Removed STATE_STARTUP.
- New globals: `search_query`, `search_results`, `search_results_error`, `search_scroll_offset`, `_search_content_height`, `keyboard_mode`, `previous_state`.
11-step plan, all within `records_on_the_day.py`:
### Splash screen (STATE_HOME)
1. **State constants + globals** — Add `STATE_HOME` (4), `STATE_SEARCH_INPUT` (5), `STATE_SEARCH_RESULTS` (6). Remove `STATE_STARTUP`. Add `search_query`, `search_results`, `keyboard_mode`, `previous_state` globals.
2. **`fetch_search_results()`** — New API client calling `GET /api/v1/collection?q=<encoded>&limit=20`. Returns `(records_list, error_flag)`. Depends on ML-176.1 for the backend `q` parameter.
3. **Splash screen (`STATE_HOME`)**`draw_home_screen()` with two large buttons: "Search Collection" and "Today's Records".
4. **On-screen keyboard (`STATE_SEARCH_INPUT`)**`draw_search_input()` with 3-row QWERTY + numbers keyboard. Hit-test via `_keyboard_hit_test()`. Touch handler `handle_search_input_touch()`. Visual key-press feedback. OK button dimmed when query empty.
5. **Search results (`STATE_SEARCH_RESULTS`)** — Reuses `_draw_record_row()`. Own scroll state (`search_scroll_offset`, `_search_content_height`). `prepare_records_for_display(recs=None)` made generic to support both `records` and `search_results`. Empty/error states.
6. **Navigation tracking**`previous_state` tracks whether detail was entered from day or search. Back from detail returns to correct origin.
7. **Back-to-Home** — Home button added to month header. `wake_display()` sets `state = STATE_HOME`. `redraw_current_view()` updated for new states.
8. **Boot flow** — Starts at `STATE_HOME`, no auto-fetch. User taps "Today's Records" → month view.
9. **Main loop dispatch** — Added handlers for all new states. `handle_home_touch()`. Search results drag-scroll mirrors day view.
10. **Cleanup** — Remove all `STATE_STARTUP` references.
11. **Deploy** — Verify ML-176.1 deployed → `mise run presto` → manual verification on device.
- `draw_home_screen()` with "Search Collection" and "Today's Records" buttons. Tapping "Today's Records" → month view with today highlighted. Tapping "Search Collection" → search input.
### Key design decisions
### On-screen keyboard (STATE_SEARCH_INPUT)
- "Today's Records" navigates to month view (with today highlighted), not directly to day — preserves calendar context
- Keyboard: fixed layout, lowercase only, no shift/caps, max 50 chars
- Search results: 20 per page, no infinite scroll. Own scroll state per AGENTS.md rules.
- `prepare_records_for_display()` parameterized to accept optional list — avoids duplicating the entire display-prep pipeline
- QWERTY layout (3 rows) + numbers/symbols. Bottom row: [123/ABC] [Space] [Backspace] [OK]. OK dimmed when query empty. `_keyboard_hit_test()` maps touch to action. `handle_search_input_touch()` dispatches all actions. Visual feedback via `_flash_key()`.
### Search results (STATE_SEARCH_RESULTS)
- Reuses `_draw_record_row()`. Own scroll state (`search_scroll_offset`, `_search_content_height`). Header: "Search: <query>" with truncation. Empty: "No records found". Error: "Could not reach server" with retry-on-tap.
### API client
- `fetch_search_results(query)``GET /api/v1/collection?q=<encoded>&limit=20`. Returns `(records_list, error_flag)`.
### Generic display pipeline
- `prepare_records_for_display(recs=None)` and `preload_record_thumbnails(recs=None)` accept optional list. Height cache tracked per source.
### Navigation tracking
- `previous_state` tracks detail origin (STATE_DAY / STATE_SEARCH_RESULTS). Back → correct origin. `draw_record_detail()` reads from `search_results` or `records`.
### Back-to-Home
- Month header gains "H" Home button. `wake_display()` always sets `state = STATE_HOME`. Search input header Back → Home.
### Boot flow
- Starts at `draw_home_screen()`, no auto-fetch. User taps a button.
### Main loop
- New dispatches for STATE_HOME, STATE_SEARCH_INPUT, STATE_SEARCH_RESULTS (drag scroll mirrors day view).
### Touch helpers
- `touch_to_record_index()` accepts optional `recs` and `offset` params.
### Verification
- Syntax check passes (`python3 py_compile`). No `STATE_STARTUP` references remain.
