# LLM Gateway Final Hardening Handoff — 2026-05-12

## Summary

- Hardened GitHub Copilot bridge:
  - Loopback-only default: `COPILOT_BRIDGE_HOST=127.0.0.1`.
  - Health endpoint remains available when underlying `copilot-api` is starting, unavailable, or auth-blocked.
  - Health now reports `auth_required`, package/version, last startup/output, and warns while `COPILOT_API_PACKAGE=copilot-api@latest`.
  - Existing spawn/restart behavior from Erik was preserved.
- Dashboard client coverage now reports bridge runtime state per client:
  - Codex -> `codex`.
  - Claude Code -> `claude-code`.
  - Microsoft Copilot -> `m365-copilot-bridge`.
  - GitHub Copilot -> `copilot-bridge`.
  - ChatGPT/OpenAI Desktop -> `chatgpt-bridge`.
- Deployed changed dashboard artifacts and restarted only `copilot-bridge` and `llm-gateway`.

## Live Verification

- Public Gateway health: `status=ok`, database `connected`.
- Client coverage, 24h:
  - Codex Desktop / CLI: `live`, bridge ready, `requestCount=3`, `tokensSaved=4067`.
  - Claude Desktop / Claude Code: `live`, bridge ready, `requestCount=28`.
  - Microsoft Copilot: local process detected, bridge `auth_required`.
  - GitHub Copilot: local process detected, bridge `auth_required`.
- Copilot bridge direct health:
  - `status=auth_required`.
  - `host=127.0.0.1`.
  - `copilot_api_package=copilot-api@latest`.
  - Detail: authorize GitHub device login shown in bridge logs.
- Fresh compression proof:
  - Request `chatcmpl-1778621358742-cascdms`.
  - Caller `final-repeat-compression-smoke`.
  - Model `qwen2.5:14b`.
  - Compression `ctxlean:verbatim_compact`.
  - Tokens `8882 -> 106`, saved `8776`, savings `98.81%`.

## Remaining Boundaries

- Gateway tracks and compresses only traffic that enters the Gateway/Companion before provider execution.
- GitHub Copilot and Microsoft Copilot cannot be counted until their real account/device auth is completed.
- `copilot-api@latest` should be pinned before treating the GitHub Copilot bridge as fully production-stable.
- Erik direct SSH was intermittent/refused during deploy; Cloudflare SSH worked with `GODEBUG=netdns=go+1`.
