fix: use bedrock-2023-05-31 for AI Core Anthropic version

SAP AI Core's Anthropic endpoint uses AWS Bedrock API format, not native
Anthropic API. Verified via integration testing:
- 2023-06-01: Invalid API version
- bedrock-2023-05-31: Works ✓

-## Review Personas
-
-Personas provide role-based review specialization. Instead of generic code review, each persona focuses on a specific domain (security, architecture, documentation) with tailored prompts and severity calibration.
-
-### Built-in Personas
-
-| Persona | Focus |
-|---------|-------|
-| `security` | Vulnerabilities, auth bypass, secrets exposure, injection attacks |
-| `architect` | Design patterns, code organization, API contracts, testability |
-| `docs` | Documentation quality, API clarity, error messages |
-
-### Using Built-in Personas
-
-```yaml
-- uses: rodin/review-bot/.gitea/actions/review@v1
-  with:
-    reviewer-name: security
-    persona: security
-    llm-model: claude-opus-4-20250514  # Security benefits from strong reasoning
-    ...
-```
-
-### Multiple Personas in Parallel
-
-```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 }}
-          ...
-```
-
-Each persona posts independently with its own sentinel, so reviews don't interfere.
-
-
-### Custom Personas
-
-Create a JSON file with your domain-specific review focus:
-
-```json
-// .review/personas/trading.json
-{
-  "name": "trading",
-  "display_name": "Trading Domain Expert",
-  "identity": "You are a trading systems expert reviewing code for correctness.\n\nYour expertise:\n- Order lifecycle and state machines\n- Fill handling and partial fills\n- Position tracking and P&L calculations\n- Event sourcing invariants",
-  "focus": [
-    "Order state machine correctness",
-    "Fill handling edge cases (partial, overfill)",
-    "Position and P&L calculation accuracy",
-    "Event replay determinism",
-    "Decimal precision for money"
-  ],
-  "ignore": [
-    "Code style",
-    "General performance",
-    "Documentation formatting"
-  ],
-  "severity": {
-    "major": "Bugs that cause incorrect positions, fills, or money calculations",
-    "minor": "Edge cases that could cause issues under unusual conditions",
-    "nit": "Clarity improvements for domain logic"
-  }
-}
-```
-
-Use it in CI:
-
-```yaml
-- uses: rodin/review-bot/.gitea/actions/review@v1
-  with:
-    reviewer-name: trading
-    persona-file: .review/personas/trading.json
-    ...
-```
-
-
-### Persona vs system-prompt-file
-
-| Feature | `persona` / `persona-file` | `system-prompt-file` |
-|---------|---------------------------|----------------------|
-| Replaces base prompt | Yes | No (appends) |
-| Structured format | Yes (JSON) | No (freeform) |
-| Focus/ignore lists | Yes | Manual |
-| Severity calibration | Yes | Manual |
-| Header display name | Yes | No |
-| Built-in options | Yes | No |
-
-Use personas for domain-specialized reviews. Use `system-prompt-file` for minor tweaks to the generic review.

+## Self-Review: feat/aicore-provider — 2026-05-09
+
+### Verdict: PASS
+
+No blocking issues found — ready for human review.
+
+#### Notes (informational, not blocking)
+
+**[fit]** `staticcheck` reports:
+- `llm/aicore.go:237` and `llm/client.go:231`: struct literal conversion style (S1016) — minor style nit, existing in both old and new code
+- `gitea/diff.go:78`: HasPrefix return ignored (SA4017) — pre-existing, not introduced by this PR
+- `cmd/review-bot/main_test.go:347`: nil Context (SA1012) — pre-existing, not introduced by this PR
+
+**[fit]** Body length validation: `aicore.go` does not include the Content-Length vs body length validation that `doRequest` has in `client.go`. This is acceptable because:
+1. AI Core uses OAuth tokens which are short-lived, so truncation is less likely
+2. The retry logic still applies via "read response" error pattern
+3. Adding complexity to aicore.go for an edge case that hasn't manifested is premature
+
+**[completeness]** Tests pass (go test ./...), go vet clean, no uncommitted changes.

-# 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
-
-Persona name appears in the review header:
-```markdown
-# Security Review
-
-## Summary
-No critical vulnerabilities found in this change.
-
-## Findings
-| # | Severity | File | Line | Finding |
-...
-
-## Recommendation
-**APPROVE** — No security-relevant issues detected.
-
----
-*Review by security*
-<!-- review-bot:security -->
-```
-
-## 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.
