Subject: [PATCH 1/3] refactor: fix critical/high issues from code review

Security:
- FORGE content safety scan (isCodeSafe) blocks dangerous code patterns
- ORACLE max_tokens centralized via getMaxOracleOutputTokens()
- Macro data sanitized for prompt injection (sanitizeMacroText)
- FORGE protected file prefixes and backslash path traversal check
- FORGE line-count uses actual diff, not net line change
- API keys stripped from error logs (sanitizeErrorMessage)

Architecture:
- Extracted shared utils (salvageJSON, stripSurrogates, extractJSON, paths, groupBy)
- Cached loadAllJournalEntries() per session with invalidation

Performance:
- AbortSignal.timeout() on all 14 fetch calls (10-20s)
- Phase 1 data fetches parallelized via Promise.allSettled

Testing: 73 new tests (214 total across 9 files)

 All external input passes through `security.ts` before reaching the AI:
 
 - **Prompt injection**: 20+ regex patterns block classic attacks (instruction override, role hijack, jailbreak tokens)
-- **Cost limits**: max 5 issues, 4000 total chars, 8192 output tokens for ORACLE, max 2 FORGE changes per session, max 200 lines per FORGE patch
+- **Cost limits**: max 5 issues, 4000 total chars, max 2 FORGE changes per session, max 200 lines per FORGE patch
+- **ORACLE token limit**: ORACLE has its own centralized token limit (`MAX_ORACLE_OUTPUT_TOKENS = 8192`) via `getMaxOracleOutputTokens()` in `security.ts`, separate from the default `MAX_OUTPUT_TOKENS = 4096` used by AXIOM/FORGE
 - **AXIOM output sanitization**: new rules checked for injection, weights clamped 1-10, self-task categories/priorities validated against allowlists
 - **Meta-rule blocking**: rules referencing 2+ other rules with enforcement keywords are blocked to prevent self-referential spirals
 - **Self-task deduplication**: normalized word overlap >70% prevents duplicate issues
 - **Foundational rule protection**: rules r001-r010 cannot be removed, minimum rule count enforced
-- **FORGE file protection**: `security.ts`, `forge.ts`, `session.yml`, `README.md` can never be modified by FORGE
+- **FORGE file protection**: `security.ts`, `forge.ts`, `session.yml`, `README.md` can never be modified by FORGE; files with `security` or `forge` prefixes are also blocked
+- **FORGE content safety**: AI-generated code is scanned by `isCodeSafe()` before writing to disk — blocks secret exfiltration, child_process, exec, filesystem mutations, and eval
+- **Macro data sanitization**: GDELT article fields and Alpha Vantage ticker data are sanitized via `sanitizeMacroText()` against injection patterns before entering the ORACLE prompt
+- **Error log sanitization**: API keys are stripped from error messages via `sanitizeErrorMessage()` before logging

+# Code Review Fixes — 2026-03-15
+
+Findings from architecture, security, and performance review.
+
+## Critical
+
+- [x] **FORGE content safety scan** — `isCodeSafe()` scans for dangerous patterns before writing to disk
+- [x] **ORACLE max_tokens bypass** — centralized via `getMaxOracleOutputTokens()` in security.ts
+
+## High — Security
+
+- [x] **Sanitize macro data for prompt injection** — `sanitizeMacroText()` checks GDELT/Alpha Vantage fields against injection patterns
+- [x] **Strengthen FORGE protected file checks** — `PROTECTED_PREFIXES` blocks security-/forge- filenames, backslash path traversal check added
+- [x] **Fix FORGE line-count metric** — now counts actual diff lines via set comparison, not net line change
+- [x] **Strip API keys from error logs** — `sanitizeErrorMessage()` redacts api_key params before logging
+- [ ] **Document GITHUB_TOKEN scope** — note in CLAUDE.md that only the default `GITHUB_TOKEN` should be used, not PATs
+
+## High — Architecture
+
+- [x] **Extract shared utilities into `src/utils.ts`** — salvageJSON, stripSurrogates, extractJSONFromResponse, path constants, groupBy
+- [x] **Cache `loadAllJournalEntries()` per session** — in-process cache with invalidation on save
+
+## High — Performance
+
+- [x] **Add `AbortSignal.timeout()` to all fetch calls** — 10s markets, 15s macro, 20s GitHub API
+- [x] **Parallelize Phase 1 data fetches** — markets, macro, issues, self-tasks via Promise.allSettled
+
+## High — Testing
+
+- [x] **Add tests for core modules** — forge.ts (28 tests), utils.ts (25 tests), expanded security + macro tests
+
+## Medium — Security
+
+- [ ] **ReDoS mitigation** — bound `\s+` to `\s{1,10}` in injection patterns (`security.ts:10-48`)
+- [ ] **GitHub Pages XSS** — allowlist bias values before using in HTML attributes (`journal.ts:213`)
+- [ ] **Sanitize resolvedSelfTasks comments** — validate length and content before posting as GitHub comments (`security.ts:340`)
+
+## Medium — Code Quality
+
+- [ ] **Fix crash handler phase label** — catch-all in `runSession()` always logs `phase: "oracle"` regardless of actual phase (`agent.ts:468-471`)
+- [ ] **Break up `runSession()`** — 325-line God function, extract into phase functions
+- [ ] **Break up `runAxiomReflection()`** — 315-line function doing prompt building, API call, validation, memory evolution, and self-task management
+- [ ] **Cap `sessions.json`** — unbounded growth, should archive or cap to last N entries
+- [ ] **Empty catch blocks** — 12 across agent.ts and axiom.ts swallow errors silently, add at minimum `console.debug()`
+
+## Low
+
+- [ ] **Use `npm ci` in GitHub Actions** — currently `npm install`, lock file not strictly enforced
+- [ ] **Add `dist/` to .gitignore** — `package.json` declares `main: dist/index.js`
+- [ ] **Externalize instrument list** — 17 instruments hardcoded in `markets.ts:11-29`
+- [ ] **TruffleHog unverified secrets** — `--only-verified` flag misses rotated keys in git history

Subject: [PATCH 2/3] refactor: fix medium and low issues from code review

Security:
- ReDoS mitigation: bounded \s+ to \s{1,10} in injection patterns
- GitHub Pages XSS: bias values allowlisted before HTML injection
- resolvedSelfTasks: issueNumber validated, comment HTML stripped + capped

Code Quality:
- Crash handler now logs actual phase, not hardcoded "oracle"
- sessions.json capped to 500 entries (~8 months)
- Debug logging added to 9 empty catch blocks in agent.ts/axiom.ts

Low:
- npm install -> npm ci in GitHub Actions
- dist/ added to .gitignore
- TruffleHog --only-verified flag removed

Testing: 7 new tests (221 total)
