# Dependency graph
|
|
requires:
|
|
- phase: 01-omitted-number-analysis
|
|
provides: 01-01 backend missingNum endpoint + 01-02 history toolbar button + Layer dialog UI
|
|
provides:
|
|
- Complete end-to-end integration: button -> dialog -> AJAX -> backend -> result display
|
|
- Boundary case handling: colorMap not loaded, empty data, AJAX failure, duplicate click prevention
|
|
- XSS mitigation: jQuery .text() used for DOM injection instead of string concatenation
|
|
affects: [future omission trend analysis, any feature reusing missingNum endpoint]
|
|
|

# Tech tracking

added: []
|
|
patterns:
|
|
- "Button disabled during AJAX request via $btn.prop('disabled', true/false) with complete callback"
|
|
- "Safe DOM rendering: jQuery .text() for numbers and labels, .css() for colors — no .html() with external data"
|
|
- "Color map loaded guard: queryMissingNum checks colorMapLoaded before dispatching AJAX"
|

key-files:

created: []

|
modified:
|
|
- public/assets/js/backend/history.js (added button disable/restore, XSS-safe rendering via jQuery DOM methods)
|
|
|
|
key-decisions:
|
|
- "Used jQuery .text() instead of string concatenation for rendering number and omission label — mitigates XSS from untrusted API data (T-01-07)"
|
|
- "Button disabled state managed via $btn.prop('disabled', true) before AJAX, restored in complete callback — ensures single-request-at-a-time (T-01-08)"
|
|
- "No code changes needed for colorMapLoaded guard, empty data handling, or error callback — already correct from plan 01-02"
|
|
|
|
patterns-established:
|
|
- "All external data (numbers, omission counts) rendered via .text() — colors applied via .css('background-color', ...) — never .html() with API data"
|
|
- "AJAX request lifecycle: disable button -> show spinner -> request -> success/error -> complete restores button"

# Phase 01 Plan 03: Integration Verification & Boundary Case Handling Summary
|
|
|
|
**End-to-end AJAX integration verified between history.js and History::missingNum() endpoint, with XSS-safe rendering and duplicate-click prevention**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** ~5 min
|
|
- **Started:** 2026-04-21T13:12:00Z
|
|
- **Completed:** 2026-04-21T13:17:00Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 1 (history.js)
|
|
|
|
## Accomplishments
|
|
- Verified all 5 boundary cases: colorMap not loaded, empty data, AJAX failure, button duplicate-click, color fallback
|
|
- Fixed XSS vulnerability in renderMissingNum by replacing string concatenation with jQuery .text() and .css() DOM methods
|
|
- Added button disabled/restore lifecycle to prevent duplicate AJAX requests during pending query
|
|
- Human verification passed: all 9 steps in plan confirmed working in browser (button, dialog, query, results, boundary values, close, reopen)
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Verify integration链路 and完善边界情况处理** - `bc8d38c` (fix)
|
|
- Added `$btn.prop('disabled', true)` before AJAX request
|
|
- Added `complete` callback to restore button state
|
|
- Replaced string concatenation rendering with jQuery `.text()` for XSS safety
|
|
2. **Task 2: Human verification of complete feature pipeline** - approved by user in browser
|
|
|
|
**Plan metadata:** committed with SUMMARY.md
|
|
|
|
## Files Created/Modified
|
|
- `D:/code/php/amlhc/.claude/worktrees/agent-a4fa6413/public/assets/js/backend/history.js` - Added button disable/restore, XSS-safe DOM rendering via jQuery .text()/.css()
|
|
|
|
## Decisions Made
|
|
- Used jQuery `.text()` for rendering number values and omission labels — this satisfies threat T-01-07 (tampering via DOM injection) by ensuring no HTML injection of external data
|
|
- Used `.css('background-color', color)` for ball colors — style-only, no HTML content risk
|
|
- Kept `colorMapLoaded` guard, `data.length === 0` check, and `error` callback as-is from plan 01-02 — all three were already correctly implemented
|
|
|
|
## Deviations from Plan
|
|
|
|
### Auto-fixed Issues
|
|
|
|
**1. [Rule 2 - Missing Critical] Fixed XSS vulnerability in renderMissingNum**
|
|
- **Found during:** Task 1 (boundary case verification)
|
|
- **Issue:** Plan 01-02 used string concatenation to build HTML with `data[i].num` and `data[i].omit` directly injected into `.html()` — if API returns malicious data, this creates XSS vector (threat T-01-07)
|
|
- **Fix:** Replaced with jQuery DOM methods: `.text(data[i].num)` for the ball number, `.text(__('Missing') + ' ' + data[i].omit + ' ' + __('periods'))` for the label, `.css('background-color', color)` for ball color
|
|
- **Files modified:** public/assets/js/backend/history.js
|
|
- **Verification:** Confirmed no `.html()` calls with external data in renderMissingNum; all data injected via `.text()` or `.css()`
|
|
- **Committed in:** `bc8d38c` (Task 1 commit)
|
|

|
|
|
|
**Total deviations:** 1 auto-fixed (1 missing critical - XSS prevention)
|
|
**Impact on plan:** Essential for security. No scope creep — aligns with existing threat model T-01-07.

## Issues Encountered
|
|
- None
|
|
|
|
## Threat Surface Scan
|
|
|
|
| Flag | File | Description |
|
|
|------|------|-------------|
|
|
| threat_flag: XSS (mitigated) | public/assets/js/backend/history.js | renderMissingNum now uses `.text()` for all external data injection — no `.html()` with API response data |
|
|
|
|
## Known Stubs
|
|
None. All data rendering is fully wired to the backend `missingNum` endpoint.
|
|
|
|
## Next Phase Readiness
|
|
- Full integration verified and working
|
|
- XSS mitigation in place for DOM rendering
|
|
- Ready for next phase (omission trend analysis or other lottery features)
|
|
- All 3 OMIT requirements (OMIT-02, OMIT-03, OMIT-04) satisfied
