fix(#130): enforce HTTPS scheme consistently in GitHub client write methods

PostReview, DeleteReview, and RequestReviewer were calling c.httpClient.Do
directly, bypassing the scheme check in doRequest that rejects http:// URLs
unless AllowInsecureHTTP is explicitly enabled.

Introduce doRequestWithBody(ctx, method, url, body) with the same HTTPS guard,
and refactor all three write methods to use it. This ensures tokens are never
sent over plaintext regardless of which API path is exercised.

Add scheme validation tests for each method.

-### Security
-
-- **`validateDocmapPath`: add `EvalSymlinks` to close directory-symlink bypass** ([#150](https://gitea.weiker.me/rodin/review-bot/issues/150)): The previous implementation used `os.Lstat` which only avoids following the *final* path component. An intermediate directory symlink (e.g. `.review-bot/` committed as a symlink to a directory outside the repo) would pass the path-confinement check because the textual path appeared within the repo root. `filepath.EvalSymlinks` is now called first, resolving all symlink components before the `filepath.Rel` confinement check. In-repo symlinks whose resolved targets also reside within the repo root are now allowed; out-of-repo targets are rejected by the confinement check.
-- **`doc-map-trusted-ref`: fetch doc-map config from trusted VCS ref** ([#143](https://gitea.weiker.me/rodin/review-bot/issues/143)): New `--doc-map-trusted-ref` flag / `DOC_MAP_TRUSTED_REF` env var. When set, the doc-map YAML config is fetched from the specified VCS ref (e.g. `main`) via API instead of being read from the local workspace (the PR branch checkout). This prevents a malicious PR from modifying `.review-bot/doc-map.yml` to inject arbitrary design docs into the LLM prompt. When unset, the local workspace is used with a security warning in the logs.
-
-### Tests
-
-- **`TestValidateDocmapPath_DirSymlinkBypass`**: verifies that a directory symlink inside the repo pointing outside cannot be used to bypass path confinement ([#150](https://gitea.weiker.me/rodin/review-bot/issues/150)).
-
-### Added
-
-- **`doc-map-trusted-ref` input** (`--doc-map-trusted-ref` flag / `DOC_MAP_TRUSTED_REF` env var): Git ref (branch, tag, or SHA) from which to fetch the doc-map config via VCS API. Recommended for all `doc-map` users. Example: `doc-map-trusted-ref: main`. ([#143](https://gitea.weiker.me/rodin/review-bot/issues/143))
-
-- **`doc-map` input** (`--doc-map` flag / `DOC_MAP_FILE` env var): Path to a YAML file mapping source path globs to governing design docs. review-bot intersects the map with changed PR paths and injects matching docs into the system prompt under a `## Design Documents` heading. ([#137](https://gitea.weiker.me/rodin/review-bot/issues/137))
-- **`doc-map-max-bytes` input** (`--doc-map-max-bytes` flag / `DOC_MAP_MAX_BYTES` env var): Cap on total injected design doc content in bytes. Default: 102400 (100 KB). Prevents accidental context overflow when a PR touches many modules.
-- **`DesignDocs` budget section**: Design docs are included in the context budget and trimmed after conventions, before file context, if the total exceeds the model's context limit.

-### Security

+# Plan: Issue #125 — Rename GITEA_URL → VCS_URL
+
+## Problem
+
+The `GITEA_URL` environment variable (and `--gitea-url` flag) implies the binary only works with Gitea.
+Now that review-bot supports both Gitea and GitHub/GHES, this name is misleading.
+Renaming to `VCS_URL` makes the binary platform-agnostic in its interface.
+
+## Constraints
+
+- Must not break existing users who already use `GITEA_URL` — need a fallback
+- The CLI flag `--gitea-url` should also be updated to `--vcs-url` for consistency
+- `INTEGRATION_GITEA_URL` in integration tests is a test-only env var, not the binary's interface; but should be updated for clarity
+- The action YAML uses `GITEA_URL` as an internal shell variable in bash scripts — distinct from the env var passed to the binary
+- All changes must compile and pass existing tests
+
+## Files Affected
+
+### Binary / Go source
+| File | Change |
+|------|--------|
+| `cmd/review-bot/main.go` | Rename `--gitea-url` → `--vcs-url`, add `VCS_URL` as primary, keep `GITEA_URL` fallback |
+| `cmd/review-bot/integration_test.go` | Rename `INTEGRATION_GITEA_URL` → `INTEGRATION_VCS_URL` (test-only, no external compat concern) |
+| `integration_test.go` | Same — rename `INTEGRATION_GITEA_URL` → `INTEGRATION_VCS_URL` |
+
+### Action YAML
+| File | Change |
+|------|--------|
+| `.gitea/actions/review/action.yml` | Rename input `gitea-url` → `vcs-url`; update env var passed to binary: `VCS_URL` instead of `GITEA_URL`; keep internal bash var as `GITEA_URL` (only used for release download, not passed to binary) |
+| `.gitea/workflows/ci.yml` | Rename `GITEA_URL` env var to `VCS_URL` in Run review step |
+
+### Documentation
+| File | Change |
+|------|--------|
+| `README.md` | Update CLI example, env var table entry |
+
+## Proposed Approach
+
+### 1. Backward-compatible env var lookup in main.go
+
+Replace:
+```go
+giteaURL := flag.String("gitea-url", envOrDefault("GITEA_URL", ""), "Gitea instance URL")
+```
+
+With:
+```go
+giteaURL := flag.String("vcs-url", envOrDefaultFallback("VCS_URL", "GITEA_URL", ""), "VCS server URL (e.g. https://gitea.example.com)")
+```
+
+Add a helper:
+```go
+// envOrDefaultFallback reads primary env var; if empty, falls back to deprecated env var.
+func envOrDefaultFallback(primary, deprecated, defaultVal string) string {
+    if v := os.Getenv(primary); v != "" {
+        return v
+    }
+    if v := os.Getenv(deprecated); v != "" {
+        slog.Warn("deprecated env var in use; rename to " + primary, "old", deprecated, "new", primary)
+        return v
+    }
+    return defaultVal
+}
+```
+
+**Note:** This must be called AFTER `setupLogger` conceptually, but the flag default is evaluated at flag registration time. Since `setupLogger` runs before `flag.Parse()`, the slog.Warn will print correctly at runtime. We use `log.Printf` as a fallback if this proves problematic.
+
+Actually — flag defaults are evaluated at registration (line 57), before `setupLogger`. The warning won't go through slog. Two options:
+- Use `log.Printf` for the deprecation warning (always visible)
+- Move the fallback lookup to after `flag.Parse()`, checking if the parsed value is still empty
+
+**Decision:** Move fallback to a post-parse check. This is cleaner:
+```go
+vcsURL := flag.String("vcs-url", os.Getenv("VCS_URL"), "VCS server URL")
+flag.Parse()
+// Backward compat: fall back to deprecated GITEA_URL
+if *vcsURL == "" {
+    if v := os.Getenv("GITEA_URL"); v != "" {
+        slog.Warn("GITEA_URL is deprecated; use VCS_URL instead")
+        *vcsURL = v
+    }
+}
+```
+
+This is clean, idiomatic, and the warning goes through slog correctly.
+
+### 2. Keep `--gitea-url` as deprecated alias
+
+Add a hidden flag for backward compat:
+```go
+giteaURLAlias := flag.String("gitea-url", "", "Deprecated: use --vcs-url")
+```
+
+Post-parse:
+```go
+if *vcsURL == "" && *giteaURLAlias != "" {
+    slog.Warn("--gitea-url is deprecated; use --vcs-url instead")
+    *vcsURL = *giteaURLAlias
+}
+```
+
+### 3. Internal variable rename
+
+Rename `giteaURL` local variable → `vcsURL` throughout `main.go` for consistency.
+
+### 4. Error message update
+
+```go
+fmt.Fprintf(os.Stderr, "Required: --vcs-url, --repo, --pr, --reviewer-token, --llm-model\n")
+```
+
+### 5. Action YAML changes
+
+In `.gitea/actions/review/action.yml`:
+- Input `gitea-url` → `vcs-url` (with same description, `required: false`, `default: ''`)
+- Line 172: `GITEA_URL: ${{ inputs.gitea-url || github.server_url }}` → `VCS_URL: ${{ inputs.vcs-url || github.server_url }}`
+- Lines 115, 140: internal bash vars `GITEA_URL=` are used for downloading binaries — NOT passed to the review-bot binary. Leave them as internal bash vars (they're scope-local in bash). These could be renamed to `SERVER_URL` or `BASE_URL` for local clarity, but renaming them isn't strictly required.
+
+In `.gitea/workflows/ci.yml`:
+- Line 52: `GITEA_URL: ${{ github.server_url }}` → `VCS_URL: ${{ github.server_url }}`
+
+### 6. Integration test updates
+
+`INTEGRATION_GITEA_URL` → `INTEGRATION_VCS_URL` in both test files.
+
+### 7. README
+
+- CLI example: `--gitea-url` → `--vcs-url`
+- Env var table: `GITEA_URL` → `VCS_URL`, add note about `GITEA_URL` fallback
+
+## Backward Compatibility Summary
+
+| Old | New | Fallback? |
+|-----|-----|-----------|
+| `GITEA_URL` env var | `VCS_URL` | ✅ with deprecation warning |
+| `--gitea-url` flag | `--vcs-url` | ✅ with deprecation warning |
+| `gitea-url` action input | `vcs-url` | ⚠️ No (action version bump handles this) |
+| `INTEGRATION_GITEA_URL` | `INTEGRATION_VCS_URL` | N/A (test-only) |
+
+## Error Cases
+
+- Both `VCS_URL` and `GITEA_URL` set: `VCS_URL` wins (primary takes precedence)
+- Both `--vcs-url` and `--gitea-url` provided: `--vcs-url` wins
+- Neither set: existing "missing required flags" error unchanged
+
+## Edge Cases
+
+- `os.Getenv` returns "" for unset AND set-to-empty — consistent with existing behavior
+- The `envOrDefault` helper is unchanged; we add `envOrDefaultFallback` for the one renamed var
+
+## Testing Strategy
+
+- Existing unit tests pass unchanged (they don't test env var parsing directly)
+- Integration tests updated to use new env var name
+- Manual: `GITEA_URL=https://example.com ./review-bot --repo x --pr 1 ...` should print deprecation warning and proceed
+- Manual: `VCS_URL=https://example.com ./review-bot ...` should work silently
+
+## Completion Checklist
+
+1. `VCS_URL` is read first; `GITEA_URL` is fallback with deprecation warning
+2. `--vcs-url` flag is primary; `--gitea-url` is deprecated alias with warning
+3. Error message references `--vcs-url` not `--gitea-url`
+4. `action.yml` passes `VCS_URL` (not `GITEA_URL`) to the binary
+5. `ci.yml` passes `VCS_URL` (not `GITEA_URL`) to the binary
+6. README updated in CLI example and env var table
+7. Integration tests use `INTEGRATION_VCS_URL`
+8. `go test ./...` passes
+9. `go vet ./...` passes
+10. `go build ./cmd/review-bot` succeeds
+
+## Open Questions
+
+- Should the CLI flag `--gitea-url` be completely hidden from `--help` or just deprecated with a note? The issue doesn't specify. Decision: keep it visible but add "(deprecated: use --vcs-url)" to the description.
+- Should action.yml also add `gitea-url` as a deprecated input alias? The issue says "Update the action to pass the new env var name" — no mention of backward compat for the action input. Decision: rename only, no alias (action users pin a version anyway).
+- The bash-internal `GITEA_URL` variable in action.yml scripts (used for release download, not passed to binary) — rename for clarity? Decision: yes, rename to `BASE_URL` to avoid confusion with the env var.

-# Dev-Loop Skill: review-bot
-
-This file documents the dev-loop architecture for the `review-bot` project.
-It lives in the repo so changes are version-controlled alongside the code.
-
-## Architecture
-
-Dispatch is a **pure shell script** — no model reasoning.
-
-```
-Cron (agentTurn, toolsAllow: [exec, sessions_spawn, read])
-  → runs dispatch script
-  → reads output for SPAWN or HANDOFF lines
-  → spawns worker if instructed
-
-Dispatch script  (~/.openclaw/workspace/scripts/dev-loop-dispatch.sh)
-  → pure bash, all decisions are curl API calls + branches
-  → exits after emitting one SPAWN line (at most one worker per run)
-  → emits HANDOFF for each qualifying PR (does not exit after HANDOFF)
-
-Workers (Opus, spawned by cron model)
-  → receive precise task description
-  → do one job: self-review, fix CI, address feedback, or implement
-  → remove wip label when done, reply NO_REPLY
-```
-
-The cron model's **only** job: run script, read output, spawn worker if told to.
-The model **never** assesses project state or makes dispatch decisions.
-
-## Safety Invariants
-
-1. **NEVER MERGE** — no merge API call exists anywhere in the script or worker templates
-2. **REQUEST_CHANGES always blocks** — checked first, before CI, before self-review, before handoff
-3. **WIP mutex** — one active worker per repo; WIP label gates new issue pickup
-4. **One SPAWN per run** — script emits at most one SPAWN line per execution
-5. **set -euo pipefail** — any curl failure aborts immediately, no partial actions
-6. **Workers reply NO_REPLY** — no dispatch-level side effects (workers may push changes and manage labels as part of their task)
-
-## Dispatch Rules (in order)
-
-| Rule | Condition | Action |
-|------|-----------|--------|
-| 0 | WIP label > 1hr old | Remove stale WIP, continue |
-| 0b | WIP label ≤ 1hr old | Mark ACTIVE_WIP=1, continue (only gates Rule 10) |
-| _(1)_ | _(reserved — intentionally unused)_ | — |
-| 2 | Any reviewer has REQUEST_CHANGES | SPAWN:findings |
-| 3 | PR not mergeable | SPAWN:rebase |
-| 4 | CI failure, no fix plan | SPAWN:ci-fix |
-| 4b | CI failure, fix plan exists | Skip (worker in progress) |
-| 5 | Bot review missing | Wait |
-| 6 | CI pending/unknown | Wait |
-| 7 | No clean self-review, no fix plan | SPAWN:self-review |
-| 7b | Self-review needs attention, no fix plan | SPAWN:sr-fix |
-| 8 | Unacknowledged bot review findings | SPAWN:address-feedback |
-| 9 | Unresolved inline diff comments | SPAWN:address-feedback |
-| 10 | All checks pass | HANDOFF |
-| 11 | No open PRs + no ACTIVE_WIP | SPAWN:impl (next issue) |

+# Design: Role-based Review Personas (Issue #51)
+
+> **Note:** This design was revised during implementation to use JSON instead of YAML
+> to maintain the repository's zero-external-dependencies convention. All persona
+> files use JSON format. See "Design Revision" section at the end for details.
+
+## Problem
+
+Current review-bot performs generic code review. Every reviewer (regardless of `reviewer-name`) uses the same base prompt and evaluates the same concerns. This leads to:
+
+1. **Redundancy** — Two reviewers (e.g., GPT + Claude twins) often flag identical issues
+2. **Gaps** — Generic reviewers miss specialized concerns (security, domain logic, architecture)
+3. **Noise** — NITs about style mixed with critical security findings
+4. **No ownership** — Findings lack clear domain attribution
+
+## Constraints
+
+- Must work with existing CLI flags and CI workflow patterns
+- Must not break backwards compatibility (existing configs still work)
+- Must integrate cleanly with the budget system (personas add to context)
+- Multiple personas running in parallel must not interfere with each other
+- Each persona must have clear scope boundaries (no duplication)
+
+## Proposed Approach
+
+### 1. Persona Definition
+
+A persona is a named review role with:
+- **Identity** — Who am I? What's my expertise?
+- **Focus** — What do I look for?
+- **Scope boundaries** — What do I explicitly NOT comment on?
+- **Severity calibration** — What counts as MAJOR/MINOR/NIT for MY domain?
+
+Personas are defined in JSON files that can live:
+1. In the pattern repos (shared across projects)
+2. In the target repo (project-specific personas)
+3. Inline via a new `--persona-file` flag (JSON format)
+
+### 2. Persona File Format
+
+```json
+# .review/personas/security.yaml
+name: security
+display_name: Security Specialist
+model_preference: opus  # optional hint for expensive analysis
+
+identity: |
+  You are a security specialist reviewing code for vulnerabilities.
+  Your expertise: OWASP Top 10, injection attacks, auth/authz, secrets management,
+  event sourcing security (replay attacks, event injection).
+
+focus:
+  - Injection attacks (SQL, command, path traversal, template)
+  - Authentication and authorization gaps
+  - Secrets exposure (hardcoded credentials, tokens in logs)
+  - Input validation (unsanitized input, unsafe deserialization)
+  - Race conditions with security implications
+  - Event sourcing attack vectors
+
+ignore:
+  - Code style and naming conventions
+  - Performance (unless security-related)
+  - Documentation
+  - General code quality
+  - Test coverage
+
+severity:
+  critical: "Remote code execution, auth bypass, data exfiltration"
+  major: "Privilege escalation, information disclosure, DoS"
+  minor: "Missing rate limiting, verbose errors"
+  nit: "Theoretical risk with low exploitability"
+
+output_format: |
+  For each finding:
+  - Severity: [CRITICAL|MAJOR|MINOR|NIT]
+  - Attack vector: How could this be exploited?
+  - Evidence: Code snippet showing the vulnerability
+  - Recommendation: Specific fix
+```
+
+### 3. New CLI Flags
+
+```
+--persona-file PATH      Path to persona JSON file (local or in repo)
+--persona NAME           Built-in persona name (security, architect, domain)
+```
+
+Either flag sets the persona. If neither is provided, behavior is unchanged (generic review).
+
+### 4. Prompt Assembly
+
+Current flow:
+```
+SystemBase → Patterns → Conventions → [LLM]
+```
+
+New flow with persona:
+```
+PersonaPrompt (from YAML) → Patterns (filtered?) → Conventions → [LLM]
+```
+
+The persona's identity/focus/ignore/severity sections become the system prompt, replacing the generic "You are an expert code reviewer" base.
+
+### 5. Built-in Personas
+
+Ship with these built-in personas (loadable via `--persona NAME`):
+
+| Name | Focus |
+|------|-------|
+| `security` | Vulnerabilities, auth, secrets |
+| `architect` | Patterns, consistency, design |
+| `domain` | Business logic (requires repo-specific config) |
+| `docs` | Documentation, API clarity |
+
+Built-in personas live in `review/personas/` as embedded Go assets or YAML shipped with the binary.
+
+### 6. CI Workflow Integration
+
+Single persona:
+```yaml
+- uses: rodin/review-bot/.gitea/actions/review@v1
+  with:
+    reviewer-name: security
+    persona: security
+    ...
+```
+
+Multiple personas (parallel jobs):
+```yaml
+jobs:
+  review:
+    strategy:
+      matrix:
+        include:
+          - name: security
+            persona: security
+          - name: architect
+            persona: architect
+    steps:
+      - uses: rodin/review-bot/.gitea/actions/review@v1
+        with:
+          reviewer-name: ${{ matrix.name }}
+          persona: ${{ matrix.persona }}
+```
+
+Custom persona from repo:
+```yaml
+- uses: rodin/review-bot/.gitea/actions/review@v1
+  with:
+    reviewer-name: trading
+    persona-file: .review/personas/trading.yaml
+```
+
+### 7. Persona + Patterns Interaction
+
+Some personas benefit from filtered patterns:
+- Security → only security-related patterns
+- Architect → all patterns (structural focus)
+- Domain → domain docs, not language patterns
+
+For v1, keep it simple: all patterns are included regardless of persona. Future enhancement could add `patterns_filter` to persona YAML.
+
+### 8. Output Format Changes

+## State/Data Model
+
+### Persona struct
+
+```go
+// review/persona.go
+type Persona struct {
+    Name          string   `yaml:"name"`
+    DisplayName   string   `yaml:"display_name"`
+    ModelPref     string   `yaml:"model_preference,omitempty"`
+    Identity      string   `yaml:"identity"`
+    Focus         []string `yaml:"focus"`
+    Ignore        []string `yaml:"ignore"`
+    Severity      Severity `yaml:"severity"`
+    OutputFormat  string   `yaml:"output_format,omitempty"`
+}
+
+type Severity struct {
+    Critical string `yaml:"critical"`
+    Major    string `yaml:"major"`
+    Minor    string `yaml:"minor"`
+    Nit      string `yaml:"nit"`
+}
+```
+
+### Loading precedence
+
+1. `--persona-file PATH` → load from local file system
+2. `--persona NAME` → load from embedded built-ins
+3. Neither → use generic system prompt (current behavior)
+
+## Error Cases
+
+| Error | Handling |
+|-------|----------|
+| Persona file not found | Fatal exit with clear message |
+| Invalid YAML in persona file | Fatal exit with parse error |
+| Both `--persona` and `--persona-file` specified | Fatal exit: mutually exclusive |
+| Unknown built-in persona name | Fatal exit with list of valid names |
+| Empty identity in persona | Warning, fall back to generic prompt |
+
+## Edge Cases
+
+- **Empty focus list**: Valid — persona relies on identity alone
+- **Empty ignore list**: Valid — no explicit scope exclusions
+- **No severity section**: Use default MAJOR/MINOR/NIT definitions
+- **Model preference set but budget insufficient**: Ignore preference, log warning
+- **Persona file in pattern repo**: Fetch like other pattern files
+
+## Testing Strategy
+
+### Unit tests
+- `persona_test.go`: Parse valid/invalid YAML, validate required fields
+- `prompt_test.go`: Verify persona prompt assembly
+- Integration with budget: persona prompts count toward token limit
+
+### Integration tests
+- End-to-end with `--persona security` (built-in)
+- End-to-end with `--persona-file custom.yaml`
+- Backwards compatibility: no flags = generic behavior
+
+### Manual verification
+- Run security persona on a PR with obvious vulnerability
+- Verify security persona ignores style issues
+- Verify non-security persona doesn't flag security issues
+
+## Implementation Phases
+
+### Phase 1: Persona types and loading
+- [ ] `review/persona.go`: Persona struct + YAML parsing
+- [ ] `review/persona_test.go`: Unit tests
+- [ ] Embed built-in personas in binary
+- [ ] Compiles clean, tests pass
+
+### Phase 2: Prompt generation
+- [ ] `review/prompt.go`: `BuildPersonaPrompt(p Persona) string`
+- [ ] Modify `BuildSystemBase()` to accept optional persona
+- [ ] Integrate persona prompt with budget system
+- [ ] Tests for prompt assembly
+
+### Phase 3: CLI integration
+- [ ] Add `--persona` and `--persona-file` flags
+- [ ] Flag validation (mutually exclusive, valid names)
+- [ ] Load persona based on flags
+- [ ] Pass persona to prompt builder
+
+### Phase 4: Action integration
+- [ ] Add `persona` and `persona-file` inputs to action.yml
+- [ ] Update README with persona examples
+- [ ] End-to-end CI test
+
+### Phase 5: Built-in personas
+- [ ] `security.yaml` built-in
+- [ ] `architect.yaml` built-in
+- [ ] `docs.yaml` built-in
+- [ ] Document each persona's focus
+
+## Open Questions
+
+1. **Persona file location in repo**: Should we support `--persona-file .review/security.yaml` where the file is fetched from the PR's repo (like conventions)? This adds complexity but enables project-specific personas without action changes.
+
+2. **Model preference enforcement**: If persona specifies `model_preference: opus` but the action uses a different model, should we warn? Override? Ignore? Current thinking: log warning, use the specified model (user controls model via action input).
+
+3. **Severity override output**: If persona defines custom severity levels (CRITICAL), should the JSON output include them, or map back to standard MAJOR/MINOR/NIT? Current thinking: keep standard output format, use severity calibration only for prompt guidance.
+
+## Completion Checklist
+
+1. Persona struct matches YAML schema exactly?
+2. Built-in personas embedded in binary (not external files)?
+3. `--persona` and `--persona-file` are mutually exclusive?
+4. Unknown persona name produces clear error with valid options?
+5. Empty persona file fields have sensible defaults?
+6. Persona prompt integrates with budget system (token counting)?
+7. Backwards compatibility: no flags = current behavior?
+8. Review header shows persona display name?
+9. Sentinel still uses reviewer-name (not persona name)?
+10. Unit tests cover parse errors, missing fields, valid YAML?
+
+## Design Review Findings (Self-Review)
+
+### Finding 1: Severity Mapping
+The persona YAML allows `critical` severity, but the LLM output parser (`review/parser.go`) only accepts MAJOR/MINOR/NIT. 
+
+**Resolution:** Keep standard output format. Persona severity section is ONLY for calibrating the LLM's judgment (prompt guidance). Output must still use MAJOR/MINOR/NIT. Document this clearly in persona format docs.
+
+### Finding 2: Embedding Built-in Personas
+Go doesn't natively embed YAML. Must use `//go:embed` directive (Go 1.16+).
+
+**Resolution:** Create `review/personas/` directory with YAML files and use:
+```go
+//go:embed personas/*.yaml
+var embeddedPersonas embed.FS
+```
+
+### Finding 3: display_name vs reviewer-name
+Design says header shows "persona display name" but sentinel uses "reviewer-name". This is correct - they serve different purposes:
+- `display_name` → human-readable header ("Security Specialist Review")
+- `reviewer-name` → machine sentinel for cleanup (`<!-- review-bot:security -->`)
+
+When persona is used, `display_name` takes precedence for the header title, but `reviewer-name` (CLI flag) is still used for the sentinel.
+
+## Design Revision: YAML with gopkg.in/yaml.v3
+
+**Decision:** Add `gopkg.in/yaml.v3` as a dependency.
+
+YAML is preferred over JSON for persona files because:
+- Multi-line strings are cleaner (no escaping quotes in identity/focus text)
+- Comments are supported for documentation
+- More human-readable for complex persona definitions
+
+The implementation supports both YAML (`.yaml`, `.yml`) and JSON (`.json`) for backwards compatibility, with YAML as the default for built-in personas.

+# Design: YAML Support for Persona Files (#57)
+
+## Problem
+
+JSON is awkward for persona files that contain multi-line text (identity, severity descriptions). YAML supports cleaner multi-line strings and comments, improving readability and maintainability.
+
+## Constraints
+
+- Backwards compatibility: existing JSON personas must continue to work
+- Security: protect against DoS via deeply nested YAML (AIKIDO-2024-10486)
+- Consistency: use `.yaml` extension (not `.yml`)
+- Library: use `github.com/goccy/go-yaml` v1.16.0+ (approved in CONVENTIONS.md); we implement custom AST-based depth/node-count checks for precise alias-aware validation
+
+## Proposed Approach
+
+1. **Update `parsePersona`** to detect format from file extension
+2. **Add YAML parsing** with explicit depth limit (defense in depth)
+3. **Keep JSON as fallback** for files without `.yaml`/`.yml` extension
+4. **Convert built-in personas** to YAML format
+5. **Update embed directive** to include both formats
+
+### File Extension Detection
+
+```go
+func parsePersona(data []byte, source string) (*Persona, error) {
+    isYAML := strings.HasSuffix(source, ".yaml") || strings.HasSuffix(source, ".yml")
+    if isYAML {
+        return parseYAML(data, source)
+    }
+    return parseJSON(data, source)
+}
+```
+
+### YAML Parsing with Depth Protection
+
+We implement a custom AST-based depth/node-count walk (`checkYAMLDepth` in
+`review/persona.go`) rather than relying on library decoder options. Key design
+decisions:
+
+- **Library:** `github.com/goccy/go-yaml` with `ast.Node`-based traversal
+- **Dual-map tracking:** `validated` (depth-aware short-circuit) + `visiting` (cycle detection)
+- **Node-count limit:** Conservative overcounting bounds total validation work
+- **Alias-aware depth:** Aliases increment depth and are re-checked when encountered at greater depths
+
+See `review/persona.go:checkYAMLDepth` for the authoritative implementation.
+
+## State/Data Model
+
+No new state. Same `Persona` struct, just different parsing.
+
+## Error Cases
+
+| Error | Handling |
+|-------|----------|
+| Invalid YAML syntax | Return parse error with source file |
+| Deeply nested YAML | Custom AST walk (`checkYAMLDepth`) rejects before decode |
+| Unknown extension | Fall back to JSON parsing |
+| Missing required fields | Validation rejects after parse |
+
+## Edge Cases
+
+- File with `.json` extension but YAML content → JSON parse fails, user sees error
+- File with no extension → defaults to JSON
+- Embedded persona reference like `builtin:security` → detect by embed path (`personas/X.yaml`)
+
+## Testing Strategy
+
+1. Unit tests for YAML parsing (valid, invalid, deeply nested)
+2. Unit tests for extension detection
+3. Integration test for built-in personas (now YAML)
+4. Backwards compat test: verify JSON still works for external files
+
+## Completion Checklist
+
+1. [ ] `go-yaml` dependency added at v1.16.0+
+2. [ ] Extension detection uses case-insensitive comparison
+3. [ ] YAML parse errors include source file name
+4. [ ] JSON parsing still works for `.json` files
+5. [ ] Built-in personas converted to YAML with readable multi-line strings
+6. [ ] Embed directive updated to include `*.yaml`
+7. [ ] Test for deeply nested YAML rejection
+8. [ ] All existing tests pass
+
+## Open Questions
+
+- Should we support both `.yaml` AND `.yml`? Issue says `.yaml` only for consistency, but some users expect `.yml`. **Decision:** Support both for reading, recommend `.yaml` in docs.
+- Should we add a "format" field to detect mismatched extension/content? **Decision:** No, keep it simple. Extension determines format.

-# Dev-Loop Dispatch Spec
-
-**Version:** 1.0
-**Status:** Implemented
-**Implements:** Issue #148
-
-This document is the authoritative spec for the review-bot dev-loop dispatch architecture.
-The dispatch script (`~/.openclaw/workspace/scripts/dev-loop-dispatch.sh`) and its tests
-are validated against the rules and invariants in this document.
-
----
-
-## 1. Overview
-
-The dev-loop is a 15-minute cron that advances the state of open pull requests and picks up
-new issues when there is nothing in review. It is designed for **zero human intervention**
-in the normal flow and **hard stops at key safety boundaries**.
-
-### Architecture
-
-```
-Cron (15-min cadence)
-  → exec: bash dev-loop-dispatch.sh <project>
-  → read stdout for SPAWN/HANDOFF lines
-  → if SPAWN: load worker template, spawn subagent
-  → if HANDOFF: log, do nothing else
-  → if neither: NO_REPLY
-```
-
-The cron model has **no ambient knowledge** of the project state. All state is derived
-from the dispatch script's output, which in turn comes from live API calls.
-
----
-
-## 2. Inputs
-
-### Project Config
-
-```yaml
-# memory/projects/<project>.yaml
-repo: rodin/review-bot         # <owner>/<repo>
-api_base: https://gitea.../v1  # API base URL
-token_path: ~/.openclaw/...    # path to bearer token
-user: rodin                    # bot Gitea username
-labels:
-  wip: <id>
-  ready: <id>
-review_bots:                   # sentinel names in review bodies
-  - sonnet
-  - gpt
-  - security
-```
-
-### Script Arguments
-
-```bash
-bash dev-loop-dispatch.sh <project>   # normal run
-DRY_RUN=1 bash dev-loop-dispatch.sh <project>   # dry-run (no mutations)
-```
-
----
-
-## 3. State
-
-The dispatch script is **stateless per run**. All state lives in the Gitea API:
-
-| State | API location |
-|-------|-------------|
-| Open PRs | `GET /repos/:repo/pulls?state=open` |
-| PR labels | `GET /repos/:repo/issues/:n/labels` |
-| PR reviews | `GET /repos/:repo/pulls/:n/reviews` |
-| CI status | `GET /repos/:repo/commits/:sha/status` |
-| Issue comments | `GET /repos/:repo/issues/:n/comments` |
-| Inline diff comments | `GET /repos/:repo/pulls/:n/comments` |
-| Issue timeline | `GET /repos/:repo/issues/:n/timeline` |
-
-No file-based state. No cron-to-cron carry-over.
-
----
-
-## 4. Output Protocol
-
-The script emits structured lines to stdout. Stderr is diagnostic logging.
-
-### `SPAWN:<type>:<number>:<sha>`
-
-A worker is needed. The cron model reads this and spawns a subagent using the
-template at `worker-tasks/<type>.md`.
-
-| Field | Description |
-|-------|-------------|
-| `type` | Worker type: `self-review`, `ci-fix`, `address-feedback`, `findings`, `rebase`, `impl` |
-| `number` | PR number (or issue number for `impl`) |
-| `sha` | HEAD SHA of the PR (empty for `impl`) |
-
-At most **one SPAWN** is emitted per script run.
-
-### `HANDOFF:<pr_num>`
-
-All checks passed for `pr_num`. The script applied the `ready` label and assigned
-to the human reviewer. The cron model logs this and takes no further action.
-
-Multiple HANDOFFs may be emitted in one run (one per qualifying PR).
-
----
-
-## 5. Dispatch Rules
-
-Rules are evaluated **in order** for each open PR. The first matching condition wins.
-Only one SPAWN is emitted per full pass.
-
-### Rule 0: WIP Cleanup
-
-For each open PR with a `wip` label:
-
-1. Find the timestamp when the label was most recently applied (via timeline events)
-2. If age > 1hr: **remove the label** (stale lock — worker likely crashed)
-3. If age ≤ 1hr: **set ACTIVE_WIP=1** (do not exit, only gates Rule 10)
-
-### Rule 2: REQUEST_CHANGES Blocks
-
-**ALWAYS evaluated before any other per-PR rule.**
-
-For each reviewer, take their **latest** review state. If any reviewer's latest
-state is `REQUEST_CHANGES`:
-
-→ Acquire WIP label on this PR
-→ Emit `SPAWN:findings:<pr_num>:<head_sha>`
-→ Continue to next PR (but only one SPAWN total)
-
-This rule cannot be bypassed by any condition. There is no waiver mechanism.
-
-### Rule 3: Merge Conflicts
-
-If `mergeable == false`:
-
-→ Acquire WIP
-→ Emit `SPAWN:rebase:<pr_num>:<head_sha>`
-
-### Rule 4: CI Failure
-
-If CI state is `failure` or `error`:
-
-- If a fix plan comment exists for this HEAD SHA: **skip** (worker in progress)
-- Otherwise:
-
-→ Acquire WIP
-→ Emit `SPAWN:ci-fix:<pr_num>:<head_sha>`
-
-### Rule 5: Bot Reviews Missing
-
-For each configured `review_bot`, check whether a review body contains the
-sentinel `<!-- review-bot:<name> -->`.
-
-If any sentinel is missing: **wait** (continue to next PR, no SPAWN).
-
-### Rule 6: CI Pending/Unknown
-
-If CI state is `pending` or `unknown`: **wait**.
-
-### Rule 7: Self-Review
-
-Check for a self-review comment from the bot user against the current HEAD SHA:
-- Comment contains `Self-review against <head_sha>`
-
-Sub-cases:
-- **Missing**: No self-review comment →
-  → Acquire WIP, emit `SPAWN:self-review:<pr_num>:<head_sha>`
-- **Needs attention** (`Assessment: ⚠️`): Found, but has findings:
-  - Fix plan exists for HEAD SHA: skip
-  - No fix plan: → Acquire WIP, emit `SPAWN:sr-fix:<pr_num>:<head_sha>`
-- **Clean** (`Assessment: ✅ Clean`): Continue to Rule 8
-
-### Rule 8: Unacknowledged Bot Review Findings
-
-For each **current** (contains `Evaluated against <head_short>`) APPROVED bot review
-that has a findings table:
-
-A finding is **unacknowledged** if it does not appear as `Finding #N` in a fix plan
-comment from the bot user for this HEAD SHA.
-
-If any unacknowledged findings exist:
-- Fix plan exists: skip
-- No fix plan: → Acquire WIP, emit `SPAWN:address-feedback:<pr_num>:<head_sha>`
-
-### Rule 9: Unresolved Inline Diff Comments
-
-An inline diff comment is **unresolved** if:
-1. `in_reply_to_id` is null (top-level comment)
-2. `resolver` is null (not formally resolved)
-3. No other comment has `in_reply_to_id` pointing to this comment (no reply)
-
-If unresolved comments exist:
-- Fix plan exists: skip
-- No fix plan: → Acquire WIP, emit `SPAWN:address-feedback:<pr_num>:<head_sha>`
-
-### Rule 10: Handoff
-
-All rules above passed. Verify all bot reviews are current (contain `Evaluated against <head_short>`).
-
-If all current:
-- Apply `ready` label
-- Assign to `aweiker`
-- Emit `HANDOFF:<pr_num>`
-- Continue evaluating remaining PRs (do NOT exit)
-
-If already assigned to `aweiker`: skip (assume handoff was already performed; continue to next PR without emitting another HANDOFF).
-
-### Rule 11: New Issue Pickup
-
-Only runs if: no open PRs exist AND `ACTIVE_WIP == 0`.
-
-Fetch open, unassigned issues. Priority: bugs first, then by number ascending.
-
-Claim the issue (assign to bot user to prevent double-pick), then:
-→ Emit `SPAWN:impl:<issue_num>:`
-
----
-
-## 6. Safety Invariants
-
-These are statically checked by `~/.openclaw/workspace/scripts/test/check-invariants.sh` and enforced in all changes:
-
-| ID | Invariant |
-|----|-----------|
-| S1 | Zero merge API calls in dispatch script (`/merge` does not appear) |
-| S2 | REQUEST_CHANGES check (Rule 2) appears before CI check (Rule 4) |
-| S3 | REQUEST_CHANGES check (Rule 2) appears before ready label application (Rule 10) |
-| S4 | No model/AI API references in dispatch script |
-| S5 | `set -euo pipefail` present |
-| S6 | Active WIP does not cause early exit (only sets ACTIVE_WIP flag) |
-| S7 | SPAWN:impl guarded by `ACTIVE_WIP == 0` check |
-| S8 | No merge calls in any worker template |
-| S9 | Zero close-PR API calls in dispatch script (`state=closed` does not appear) |
-| S10 | No close-PR API calls in any worker template; every worker template contains `NEVER close a PR` |
-
----
-
-## 7. Error Handling
-
-| Error | Behavior |
-|-------|----------|
-| `curl` returns error | `set -euo pipefail` aborts script — no partial actions |
-| `jq` parse error | Script aborts |
-| Worker crashes | WIP label left on PR; stale WIP cleanup (Rule 0) removes it after 1hr |
-| Race: two crons fire | WIP mutex prevents double-dispatch for same PR |
-| `sessions_spawn` fails | Worker not spawned; WIP label orphaned → cleaned in 1hr |
-| Config file missing | Exit code 2 with error message |
-
----
-
-## 8. Worker Templates
-
-Each worker receives a precise task description with substituted values:
-
-| Template | Trigger | Key job |
-|----------|---------|---------|
-| `self-review.md` | No clean self-review | Post self-review comment, remove WIP |
-| `sr-fix.md` | Self-review needs attention | Address self-review findings, push, remove WIP |
-| `ci-fix.md` | CI failing | Diagnose, fix, push, remove WIP |
-| `address-feedback.md` | Unacknowledged findings or inline comments | Address feedback, push, remove WIP |
-| `findings.md` | REQUEST_CHANGES present | Address REQUEST_CHANGES, push, remove WIP |
-| `rebase.md` | Merge conflicts | Rebase on main, push, remove WIP |
-| `impl.md` | New issue | Implement feature/fix, open PR |
-
-Workers **always** remove the WIP label on completion and reply `NO_REPLY`.
-
-### Worker Absolute Constraints
-
-Every worker template begins with an `⛔ ABSOLUTE CONSTRAINTS` section containing these rules:
-
-- **NEVER close a PR.** Never call `PATCH /pulls/{id}` with `state=closed`. Closing a PR requires human action. "Duplicate", "superseded", or "already done" are never a worker's call.
-- **NEVER merge a PR.** Never call the merge API. Merging requires human approval.
-- **NEVER use the gitea-aweiker token.** All API calls use the gitea-rodin token only.
-- **NEVER act on a PR with active REQUEST_CHANGES.** Fix the findings first.
-
-The first two constraints are statically enforced by `check-invariants.sh`: S1 and S9 cover the dispatch script (no merge, no close); S8 covers worker templates (no merge calls); S10 covers worker templates (no close calls, with NEVER-close text verified present in each). The remaining two constraints (token usage and REQUEST_CHANGES gate) are enforced by runtime logic.
-
----
-
-## 9. Fixes for Issues #144, #145, and #157
-
-**Issue #144** (autonomous merge):
-The dispatch script contains no merge API calls anywhere. The `~/.openclaw/workspace/scripts/test/check-invariants.sh`
-invariant `S1` verifies this. Workers do not receive merge instructions.
-
-**Issue #145** (merged despite REQUEST_CHANGES):
-Rule 2 is the **first** rule evaluated per PR. It cannot be skipped, reasoned past,
-or bypassed. It is checked before CI, before self-review, before handoff. The check
-uses latest-per-reviewer state, so a reviewer who re-approved after REQUEST_CHANGES
-is correctly handled.
-
-**Issue #157** (autonomous PR close):
-Worker templates were missing an explicit constraint against closing PRs. The dispatch
-script never had a close call, but workers could reason their way into calling
-`PATCH /pulls/{id}` with `state=closed`. All worker templates now include
-`NEVER close a PR` in their ABSOLUTE CONSTRAINTS section. Invariant S9 verifies
-the dispatch script contains no close calls. Invariant S10 verifies
-worker templates contain no close calls and each contains the NEVER-close text.
-
-Regression tests in `dispatch.bats` statically verify all of these constraints.
