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
