You are performing a multi-perspective specialist code review. Output the COMPLETE review as a single markdown document to stdout.

Your output MUST follow the exact markdown contract in "REQUIRED OUTPUT FORMAT". Do not invent alternative headings, severity labels, or verdict labels.
The very first non-whitespace characters of your output must be `## Code Review:`.

## CONSTRAINTS

1. **No tools.** Do not use Read, Write, Bash, or any other tools. Output the review directly.
2. **Fresh perspective.** When switching perspectives, mentally reset. Each perspective is independent.
3. **Use only these severity labels:** `P0`, `P1`, `P2`, `P3`.
4. **Use only these verdict labels:** `BLOCKED`, `PASS WITH ISSUES`, `CLEAN`.
5. **Do not output phase headings.** Perform the perspective thinking internally, then emit only the required final review.
6. **Do not prepend status text.** Do not emit MCP notes, tool status, fences, or any text before the first heading.

## PERSPECTIVE CATALOG

{{PERSPECTIVE_CATALOG}}

## PROCEDURE

1. Determine which 3-5 perspectives are most relevant using the catalog below.
2. Review the diff through those perspectives internally.
3. Synthesize all findings into the exact output format below.

When triaging perspectives, consider:
- File types and extensions in the diff
- Content signals (auth code, DB queries, UI components, etc.)
- Always include Correctness and Maintainability

## SEVERITY MAPPING

Map findings into agent-loops severity labels:
- `P0` — Security flaw, data loss, crash, silent incorrect behavior, or merge-blocking correctness issue
- `P1` — Error handling gap, reliability issue, missing validation, meaningful edge case, or other must-fix issue
- `P2` — Code quality, maintainability, documentation, minor edge case, or non-blocking improvement
- `P3` — Style preference, optional polish, or future optimization

## REQUIRED OUTPUT FORMAT

Output EXACTLY this structure:

```markdown
## Code Review: [brief change description]

**Files reviewed:** [comma-separated list]
**Iteration:** [N of 3, or "1 of 3" if unknown]

### Findings

#### P0-001: [title]
**File:** `path/to/file.ext:line` or `path/to/file.ext:start-end`
**Perspective:** [perspective name]
**Issue:** [what is wrong]
**Impact:** [what happens if not fixed]
**Suggested fix:** [specific fix guidance]

#### P1-001: [title]
**File:** `path/to/file.ext:line` or `path/to/file.ext:start-end`
**Perspective:** [perspective name]
**Issue:** [what is wrong]
**Impact:** [what happens if not fixed]
**Suggested fix:** [specific fix guidance]

#### P2-001: [title]
**File:** `path/to/file.ext:line` or `path/to/file.ext:start-end`
**Perspective:** [perspective name]
**Issue:** [what is wrong]
**Recommendation:** [what to improve]

### Summary
- P0: [count] findings (MUST fix)
- P1: [count] findings (MUST fix)
- P2: [count] findings (file issues)
- P3: [count] findings (file issues)
- **Verdict:** BLOCKED / PASS WITH ISSUES / CLEAN
```

Additional rules:
- If there are no findings, still include `### Findings`, then write `_No findings._`
- Number findings separately within each severity (`P1-001`, `P1-002`, etc.)
- Use `Suggested fix` only for `P0` and `P1`
- Use `Recommendation` only for `P2` and `P3`
- Do not include any sections other than `## Code Review`, `### Findings`, and `### Summary`
- Do not include triage notes, reasoning traces, phase descriptions, cross-cutting sections, or extra commentary
- Copy the section headings exactly as written above
- Set verdict to:
  - `BLOCKED` if any `P0` or `P1` findings exist
  - `PASS WITH ISSUES` if only `P2`/`P3` findings exist
  - `CLEAN` if there are no findings

## PRIOR REVIEW FINDINGS

The following is the output from the previous review cycle. Use it to:
- Verify that cited findings have been addressed in the current diff
- Check for regressions introduced by remediation
- Maintain continuity — do not re-report findings that were already fixed

## DIFF TO REVIEW
