# Dependency graph
requires:
  - phase: 01-omitted-number-analysis
    provides: 01-01 backend missingNum endpoint (parallel wave, to be verified)
provides:
  - History page toolbar "Missing Number Analysis" button
  - Layer dialog with period input (default 10, range 1-100) and query button
  - AJAX integration to history/missingNum endpoint
  - Result rendering with colored num-balls and omission count display
  - Reuse of existing getColorByNum() for color consistency
affects: [01-03 integration verification, future omission trend analysis]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Layer.open({type:1}) with inline HTML for custom dialogs"
    - "jQuery $(document).off().on() for delegated event binding to prevent duplicates"
    - "Async color map loading guard before rendering colored elements"

key-files:
  created:
    - application/admin/view/history/index.html (added button to existing toolbar)
  modified:
    - public/assets/js/backend/history.js (added 4 new API methods + button handler)
    - application/admin/lang/zh-cn/history.php (added i18n keys for dialog text)

key-decisions:
  - "Used Layer.open type:1 with inline HTML instead of Layer.prompt or Fast.api.open (needs input + button + results area)"
  - "Delegated event binding on document with .off().on() to prevent duplicate handlers on tab re-initialization"
  - "queryMissingNum checks colorMapLoaded before AJAX to ensure balls render with correct colors"
  - "All text uses __() i18n function with keys in lang/zh-cn/history.php"

patterns-established:
  - "Dialog pattern: Layer.open with success callback for binding events within layero context"
  - "AJAX pattern: GET request to controller method, check ret.code==1 for success"
  - "Rendering pattern: flex-wrap grid with inline-styled num-ball components"

# Phase 01 Plan 02: History Toolbar Button + Layer Dialog UI Summary

**Missing number analysis button + Layer dialog with period input, AJAX query, and colored ball result rendering on history admin page**

## Performance

- **Duration:** ~5 min
- **Started:** 2026-04-21T13:06:00Z
- **Completed:** 2026-04-21T13:11:00Z
- **Tasks:** 2
- **Files modified:** 3 (1 toolbar, 1 JS, 1 lang)

## Accomplishments
- Added "Missing Number Analysis" button (btn-warning, fa-search icon) to history page toolbar
- Implemented Layer dialog with period number input (default 10, range 1-100) and query button
- Built AJAX integration to `history/missingNum` endpoint with loading spinner and error handling
- Implemented flex-wrap grid rendering of missing numbers as colored balls with omission count labels
- Added all required i18n keys for dialog text in Chinese

## Task Commits

Each task was committed atomically:

1. **Task 1: Add "遗漏号码" button to history page toolbar** - `4104746` (feat)
2. **Task 2: Button event binding, Layer dialog, and result rendering logic** - `538e414` (feat)
3. **Deviation: Add missing i18n language keys** - `637b847` (i18n)

## Files Created/Modified
- `D:/code/php/amlhc/.claude/worktrees/agent-a5a02f12/application/admin/view/history/index.html` - Added btn-missingnum button to toolbar
- `D:/code/php/amlhc/.claude/worktrees/agent-a5a02f12/public/assets/js/backend/history.js` - Added showMissingNumDialog, queryMissingNum, _doQueryMissingNum, renderMissingNum methods
- `D:/code/php/amlhc/.claude/worktrees/agent-a5a02f12/application/admin/lang/zh-cn/history.php` - Added 8 i18n keys for dialog text

## Decisions Made
- Used `$(document).off('click', '.btn-missingnum').on('click', '.btn-missingnum', ...)` instead of `$('#toolbar').on('click', '.btn-missingnum', ...)` to prevent duplicate binding when FastAdmin reinitializes on tab switches
- Checked `colorMapLoaded` in `queryMissingNum` before calling `_doQueryMissingNum` to ensure balls render with correct colors even if color map hasn't been loaded yet
- All display text uses `__('key')` i18n function rather than hardcoded Chinese strings, matching project convention

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 2 - Missing Critical] Added i18n keys for dialog text**
- **Found during:** Task 2 (Layer dialog implementation)
- **Issue:** The lang/zh-cn/history.php file only had Expect, OpenTime, Num7 keys. The dialog uses __() calls for 8 additional keys (Missing Number Analysis, Query Periods, Query, Loading, Missing, periods, Query failed, No missing numbers found) which would display as raw English keys instead of Chinese text
- **Fix:** Added all 8 i18n keys to application/admin/lang/zh-cn/history.php
- **Files modified:** application/admin/lang/zh-cn/history.php
- **Verification:** Verified lang file contains all keys referenced by __() calls in history.js
- **Committed in:** `637b847` (separate commit)

---

**Total deviations:** 1 auto-fixed (1 missing critical - i18n)
**Impact on plan:** Essential for correct display of Chinese text in dialog. No scope creep.

## Issues Encountered

- Worktree missing base files: The worktree was created from commit `e1cb014` which only contains planning files. All existing application code (controller, model, view, lang, JS) was untracked in the main repo and had to be copied into the worktree before modifications could be committed. Resolved by copying from the main repo's working directory.

## Threat Surface Scan

| Flag | File | Description |
|------|------|-------------|
| threat_flag: XSS | public/assets/js/backend/history.js | Dialog HTML is JS-concatenated with no external input; safe. AJAX response data displayed directly — backend should sanitize (plan 01-01 responsibility) |

## Known Stubs
None. This plan delivers UI only; data rendering depends on backend endpoint from plan 01-01.

## Next Phase Readiness
- Frontend UI complete and ready for integration with backend `missingNum` endpoint (plan 01-01)
- Requires plan 01-01 to provide `History::missingNum()` controller method with proper input validation (periods 1-100)
- Plan 01-03 will verify end-to-end integration (button -> dialog -> AJAX -> backend -> result display)
