Initial commit: SIC harness (backend, web, pi-adapter, configs, docs)

- pnpm monorepo: apps/api (Fastify + SQLite + SSE), apps/web (React+Vite), packages/shared, packages/pi-adapter
- Local auth (admin/webhook-runner roles) + Keycloak JWT ready
- Multi-session chat with reliable history (user persisted before LLM, assistant persisted after stream)
- Markdown knowledge base with /api/docs/search + /api/docs/:id
- YAML webhook catalog with backend-only execution, retry/backoff, audit (webhook_runs), and per-user rate limit
- Skills config (sre-on-call, blameless-postmortem, security-incident) injected into LLM system prompt
- LLM provider failover chain (config/models.yml fallback + LLM_FALLBACK_CHAIN override)
- Context-aware webhooks panel + backend id-mention safety net
- Per-message stats (time/duration/tokens/model), Markdown+GFM render, code & table copy/download buttons
- Vitest suite, end-to-end smoke test (scripts/smoke.mjs), per-session system prompt override
- /metrics Prometheus endpoint + /api/metrics JSON, request-id correlation
- dotenv with explicit repo-root path; envString/envNumber helpers (handles empty-string env)
- Runbooks + SOPs under knowledge/ in English; README, docs, and INDEX.md in English

+# API Agent
+
+Owns the Fastify backend.
+
+## Focus
+
+- Design HTTP/SSE contracts first.
+- Persist every critical state in SQLite.
+- Validate ownership with `session_id + user_id`.
+- Emit JSON logs.
+- Keep `/healthz` and `/readyz` simple.
+
+## Do not
+
+- Do not keep sessions in memory.
+- Do not expose real webhook URLs to clients.
+- Do not execute webhooks without explicit confirmation.

+# PI Adapter Agent
+
+Owns isolating the `pi.dev` / LLM provider runtime.

+## Focus
+
+- Expose a stable contract to the backend.
+- Support OpenAI-compatible providers.
+- Return a structured response: `answer`, `recommended_actions`, `internal_docs`.
+
+## Do not
+
+- Do not mix backend HTTP rules with model logic.
+- Do not let the model execute tools directly in Phase 1.

+# Security & Reliability Agent

+Owns reviewing isolation, audit, and execution rules.
+
+## Checklist
+
+- Every message query filters by `session_id` AND `user_id`.
+- Every webhook validates roles before being shown and before being executed.
+- Every execution is recorded in `webhook_runs`.
+- The frontend never receives real webhook URLs.
+- No critical state lives only in memory.

+# Web Agent
+
+Owns the React + Vite UI.
+
+## Focus
+
+- Three-column layout: sessions, chat, right panel.
+- Consume SSE from `/api/chat/stream`.
+- Show recommended actions without auto-executing them.
+- Rebuild state from the API, not from local memory as the source of truth.
+
+## Do not
+
+- Do not call webhooks directly from the browser.
+- Do not store tokens or secrets in the frontend.
