91384dbb2a fix: SSE stream endpoint with proper HTTP/2 stream handling and heartbeat 
- Fixed /api/stream/requests endpoint HTTP/2 INTERNAL_ERROR
- Use reply.raw.writeHead() instead of Fastify headers API for SSE
- Added 30s heartbeat to keep connection alive
- Proper event format with 'event:' and 'data:' fields
- Comprehensive error handling and cleanup on disconnect
- Mirrors working pattern from /api/stream/costs endpoint
- Resolves dashboard perpetual 'Loading...' state

93bbb44bf0 fix: remove broken @shieldx/core dependency 
The @shieldx/core dependency was referenced at an invalid file path and is
not actually used in the codebase (import is commented as TODO). Removing
this dependency resolves npm installation failures on deployment.

1d4be52c83 fix: only send HSTS header on HTTPS connections, not HTTP 
The learning process was failing to communicate with the gateway because:
1. Gateway was sending 'Strict-Transport-Security' header on HTTP responses
2. Node.js fetch respects HSTS and upgrades subsequent requests to HTTPS
3. Gateway only has HTTP listener (localhost:3103), no HTTPS
4. Result: SSL 'packet length too long' error on second request attempt

Solution: Modified registerHSTSMiddleware to only send HSTS header when
the connection is already secure (HTTPS or x-forwarded-proto: https).
HTTP connections will not get the HSTS header, preventing the forced upgrade.

4c54a6fa92 refactor: MAGATAMA pipeline code quality audit — all functions <50 lines 
Complete code quality audit of llm-gateway pipeline modules for MAGATAMA standard compliance (50-line function maximum). All pipeline functions refactored to ensure high cohesion and readability.

Pipeline module compliance (verified):
✅ llm-client.ts — Refactored callOllama() (58→26 lines) via helper extraction
✅ instrumented-llm-client.ts — All functions <50 lines (wrapper layer)
✅ router.ts — Refactored routeByScore() (81→32 lines) via delegation
✅ request-scorer.ts — 870-line file, all functions <50 lines
✅ external-providers.ts — All functions <50 lines (49-line max)
✅ post-validator.ts — All validators <50 lines

Verified:
✓ npm run build (TypeScript, zero errors)
✓ All 6 pipeline modules independently audited
✓ Production-ready for Erik deployment (PM2 ids 19+20, port 3103)

Deployment target: Gitea (192.168.178.196:3000/rene/llm-gateway)

128e18b751 feat: integrate GitHub Copilot as third LLM provider via copilot-bridge 
Add GitHub Copilot API proxy integration to LLM Gateway:

* Implement copilot-bridge service:
  - HTTP wrapper managing copilot-api (GitHub Copilot API proxy)
  - OpenAI-compatible /v1/chat/completions endpoint (port 3252)
  - Graceful startup and SIGTERM shutdown handling
  - Health check endpoint with service diagnostics

* Register copilot-bridge in provider fallback chain:
  - Position: After OpenAI, before free LLM APIs (tier 4)
  - Rate limit: 60 requests/min (GitHub Copilot API limit)
  - Models: gpt-4 (reasoning), gpt-3.5-turbo (medium)
  - Authentication: GitHub Copilot subscription (internal to copilot-api)

* Update PM2 ecosystem configuration:
  - Add copilot-bridge service definition (port 3252)
  - Configure COPILOT_BRIDGE_URL in gateway environment
  - Add copilot to LLM_PROVIDERS list

* Enhance deployment automation:
  - Update ensure-bridges.sh with copilot-bridge deployment
  - Copy service files from repo to /opt/copilot-bridge
  - Run npm install for copilot-api dependency

* Comprehensive documentation:
  - Expand DEPLOYMENT-BRIDGES.md with copilot-bridge section
  - Prerequisites: Node.js 20+, GitHub Copilot subscription
  - Authentication workflow: npm run auth with GitHub OAuth
  - Troubleshooting: subscription verification, auth cache reset

Provider chain now supports:
1. Ollama (local, free)
2. claude-bridge (Claude subscription)
3. openai-bridge (OpenAI subscription)
4. copilot-bridge (GitHub Copilot subscription) ← NEW
5. Free APIs: Cerebras, Groq, Mistral, NVIDIA, Cloudflare

c82b187548 feat: fix template resolution + add 40 routing rules for all project task types 
- completion.ts now uses taskType directly for resolvePrompt (not decision.prompt_template)
  so tip_transceiver_enrich.yaml is used instead of generic_qa fallback template
- routing-rules.yaml: +40 task type entries for TIP (8), EO Pulse (8), SwitchBlade (9),
  PeerCortex (6), NOGnet (9), internal (2) — all with correct model tier assignments
- qwen2.5:3b for fast tasks (classify, short outputs)
- qwen2.5:14b for medium (most analysis tasks)

2c5f7f6ebe fix: OLLAMA_URL env var takes precedence over hardcoded models.yaml URL 
Gateway was reading ollama_base_url from YAML (192.168.178.169) instead of
OLLAMA_URL env var (https://ollama.fichtmueller.org). Fix getOllamaBaseUrl()
to prefer process.env['OLLAMA_URL'] and update YAML default to CF tunnel.

773fd368e0 fix: parse DATABASE_URL in pool clients + extend Ollama health timeout to 15s

over individual DB_* env vars — matches ecosystem.config.cjs convention.
Ollama health check timeout increased 5→15s for Cloudflare tunnel latency.
