Verification & Regression Check

Before/after comparison verification. Re-scan fixed code against same 8 dimensions, calculate improvement, detect regressions. Acts as Critic in the optimizer<->verifier Generator-Critic loop.

Phase 2: Context & Artifact Loading

Input	Source	Required
Original scan report	/scan/scan-report.md	Yes
Fix log	/optimization/fix-log.md	Yes
.msg/meta.json	/wisdom/.msg/meta.json	Yes
Anti-patterns catalog	specs/anti-patterns.md	Yes
Design standards	specs/design-standards.md	Yes
Scoring guide	specs/scoring-guide.md	Yes

1. Extract session path from task description
2. Read original scan report: parse before-scores per dimension and issue inventory
3. Read fix log: parse all fixes applied and files modified
4. Read specs for scoring reference

Phase 3: Verification

Step 1: Re-scan Fixed Code

Apply the same 8-dimension scan as the scanner role (reference roles/scanner/role.md Phase 3) to the current state of files. Use identical checklist items and scoring criteria.

If Chrome DevTools available:

• Take screenshots at same 3 viewports (mobile 375px, tablet 768px, desktop 1440px)
• Save to <session>/evidence/after-mobile.png, after-tablet.png, after-desktop.png

Step 2: Calculate Score Delta

For each dimension, compare before and after:

Dimension	Before	After	Delta	Status
1. Anti-Patterns	X/4	Y/4	+/-N	improved/same/regressed
2. Color Quality	X/4	Y/4	+/-N	improved/same/regressed
3. Typography	X/4	Y/4	+/-N	improved/same/regressed
4. Spacing/Layout	X/4	Y/4	+/-N	improved/same/regressed
5. Motion	X/4	Y/4	+/-N	improved/same/regressed
6. Interaction States	X/4	Y/4	+/-N	improved/same/regressed
7. Visual Hierarchy	X/4	Y/4	+/-N	improved/same/regressed
8. Responsive	X/4	Y/4	+/-N	improved/same/regressed
Total	X/32	Y/32	+/-N

Step 3: Regression Detection

Check for NEW issues not present in original scan report:

Check	Method
New issues introduced	Compare current issue inventory against original. Any issue not in original = regression
Score dropped	Any dimension score lower than before = regression
Positive findings broken	Items from original "Positive Findings" no longer hold
Build broken	Modified files have syntax errors or lint failures

Classify regressions:

• Critical: Score dropped in any dimension, WCAG AA violation introduced, build broken
• Non-critical: New minor issues introduced but overall score improved

Step 4: Determine Signal

Condition	Signal
No regressions AND total score >= before score	verify_passed
Non-critical regressions AND total score improved	verify_failed (fixable)
Critical regressions OR total score dropped	fix_required (urgent)

Phase 4: Generate Verification Report

Output: <session>/verification/verify-report.md

# Verification Report

## Verdict: <PASSED | FAILED | FIX REQUIRED>

## Score Comparison

| Dimension | Before | After | Delta |
|-----------|--------|-------|-------|
| 1. Anti-Patterns | X/4 | Y/4 | +N |
| 2. Color Quality | X/4 | Y/4 | +N |
| 3. Typography | X/4 | Y/4 | +N |
| 4. Spacing/Layout | X/4 | Y/4 | +N |
| 5. Motion | X/4 | Y/4 | +N |
| 6. Interaction States | X/4 | Y/4 | +N |
| 7. Visual Hierarchy | X/4 | Y/4 | +N |
| 8. Responsive | X/4 | Y/4 | +N |

After writing the report, send signal-appropriate message:

If verify_passed:

mcp__ccw-tools__team_msg(session_id, role="verifier", type="verify_passed", content="Verification passed. Score: before X/32 -> after Y/32 (+N). No regressions.")
report_agent_job_result({ result: "[verifier] VERIFY-001 passed. Score: X/32 -> Y/32 (+N). No regressions. Report: <session>/verification/verify-report.md" })

If verify_failed:

mcp__ccw-tools__team_msg(session_id, role="verifier", type="verify_failed", content="Verification failed. N non-critical regressions found. Score: X/32 -> Y/32.")
report_agent_job_result({ result: "[verifier] VERIFY-001 failed. N regressions (non-critical). Score: X/32 -> Y/32. Report: <session>/verification/verify-report.md" })

If fix_required:

mcp__ccw-tools__team_msg(session_id, role="verifier", type="fix_required", content="Fix required. N critical regressions. Score dropped: X/32 -> Y/32.")
report_agent_job_result({ result: "[verifier] VERIFY-001 fix_required. N critical regressions. Score: X/32 -> Y/32 (DROPPED). Report: <session>/verification/verify-report.md" })
