The generateClaude() function was recursively calling itself inside
enqueueClaude(), creating a circular Promise dependency that permanently
deadlocked the claudeQueue. Any 429 rate-limit response would poison
the queue, blocking all future Claude API calls until server restart.
Fixes:
- Split retries into claudeApiCall() which is called from enqueueClaude
(not re-entering the queue on retry = no circular dependency)
- Max 3 retries with increasing backoff (10s/30s/60s)
- Add resetClaudeQueue() exported function
- Add 15-minute auto-reset stall detection to enqueueClaude
- Expose resetClaudeQueue in POST /api/blog/llm/reset-queue endpoint
- Fix merge conflict markers in index.ts (duplicate scraperRouter import)
Tier-1 Anthropic API has 40K TPM — with ~20K tokens per pipeline step,
concurrent calls immediately hit the limit. enqueueClaude() serializes
all generateClaude() calls so only one runs at a time, eliminating
the flood of 429-retry-429-retry loops.
- Auto-routes to Claude API when BLOG_LLM_PROVIDER=anthropic + ANTHROPIC_API_KEY set
- Fallback to Ollama queue when key not present
- Add rate-limit retry (429 → 10s backoff) for Claude API
- Add STEP_TECHNICAL_SANITY, STEP_SELF_HEAL, STEP_TITLE_CONTRACT_CHECK prompts
- Fix STEP_LINKEDIN_POST angle-specific hooks, remove Gold Reference repetition
