+# Security Policy
+
+The AgentKit CI/CD Diagnosis Agent takes security seriously. As a tool designed to analyze build logs and system execution context, maintaining strict data privacy, credential protection, and threat mitigation is a primary design goal.
+
+---
+
+## 🔒 Security Architecture Guarantees
+
+1. **In-Memory Zero Temporary Footprint**:
+   - All GitHub Actions `.zip` log extraction occurs directly in RAM using WebAssembly/JS streaming zip decompression (`fflate`).
+   - Log files are never written to disk or temporary file system storage.
+
+2. **Automated Secret Redaction**:
+   - Every log stream is passed through a secret sanitizer before reaching the AI model.
+   - Redacts AWS Access Keys (`AKIA...`), GitHub Personal Access Tokens (`ghp_...`, `github_pat_...`), Bearer authorization headers, and custom user secrets.
+
+3. **Session & Cookie Security**:
+   - GitHub OAuth sessions are sealed using AES-256-GCM authenticated encryption.
+   - Session cookies enforce `HttpOnly`, `Secure`, and `SameSite=Lax` protection.
+
+4. **OWASP HTTP Security Headers**:
+   - Configured with `X-Frame-Options: DENY`, `X-Content-Type-Options: nosniff`, `Referrer-Policy: strict-origin-when-cross-origin`, and `Permissions-Policy`.

+# CI/CD Diagnosis Agent
+
+## Overview
+
+The CI/CD Diagnosis Agent is an AI-powered multi-agent system that analyses GitHub Actions and GitLab CI/CD pipeline failure logs. It orchestrates 10 specialised AI agents through a Lamatic AgentKit DAG to produce a structured, verified diagnosis containing the root cause, an actionable fix, and a risk assessment — in under 30 seconds.
+
+## Purpose
+
+Developers lose hours deciphering cryptic CI/CD logs. This agent automates the entire diagnostic process: it cleans noise, extracts evidence, classifies errors, consults a domain-specific knowledge base (RAG), deduces the root cause, generates a fix, adversarially verifies the fix, and assesses risk — all without human intervention.
+
+## Flow: CICD Diagnosis
+
+### Trigger
+
+The synchronous API Request accepts a raw CI/CD log (`logContent`) and the CI platform (`ciProvider`: `github` or `gitlab`).
+
+### Processing
+
+The 10-node DAG processes the log through the following agents in sequence:
+
+1. **Log Cleaner (Code Node):** Strips timestamps, boilerplate, and redacts secrets via regex.
+2. **Evidence Extractor (LLM):** Isolates exact verbatim failure strings (stack traces, exit codes).
+3. **Error Classifier (LLM):** Maps evidence to a strict taxonomy (Dependency, Network, Permissions, etc.).
+4. **Planner (LLM):** Formulates targeted RAG search queries based on the classification.
+5. **Knowledge Retrieval (RAG Node):** Executes hybrid semantic + keyword search over the domain knowledge base.
+6. **Root Cause Analyzer (LLM):** Synthesises evidence and retrieved knowledge to deduce the mechanical failure.
+7. **Fix Generator (LLM):** Produces executable code snippets or configuration changes.
+8. **Fix Verifier (LLM):** Adversarially validates that the fix addresses the root cause.
+9. **Risk Reviewer (LLM):** Assesses the fix for security or stability risks.
+10. **Output Formatter (Code Node):** Serialises the complete pipeline state into a strict JSON API response.
+
+### Response
+
+The API Response exposes:
+
+- `classification` — Error category and confidence score.
+- `analysis` — Root cause summary with verbatim evidence citations.
+- `resolution` — Verified code fixes with syntax-highlighted snippets.
+- `risk` — Risk level (Low / Medium / High) and security warnings.
+
+### When to Use
+
+Use this agent whenever a GitHub Actions or GitLab CI pipeline fails. It is most effective for:
+- Dependency management failures (npm, pip, maven)
+- Docker build and runtime failures
+- Infrastructure-as-code errors (Terraform)
+- Permission and authentication failures
+- Network and DNS connectivity issues
+- GitHub Actions YAML configuration errors
+
+### Dependencies
+
+- Lamatic synchronous API runtime
+- Google Gemini API (configured as the LLM model in the flow)
+- A populated RAG Knowledge Base (see `knowledge/` directory)
+- The companion Next.js app (`apps/`) for the web interface
+
+## Guardrails
+
+- Never invent log lines not present in the original input.
+- Never assume technologies not explicitly mentioned in the evidence.
+- Never generate a fix before completing the Root Cause Analysis.
+- Never output a fix that introduces `rm -rf`, wildcard IAM policies, or exposed secrets without flagging it as High Risk.
+- Always cite exact log lines as evidence for every conclusion.
+- Always output valid JSON matching the declared API schema.
+
+## Integration Reference
+
+| Service | Purpose | Credential |
+|---|---|---|
+| Lamatic API | Executes the deployed diagnosis flow | `LAMATIC_API_KEY` |
+| Lamatic project | Selects the project runtime | `LAMATIC_PROJECT_ID`, `LAMATIC_API_URL` |
+| Deployed flow | Selects the diagnosis workflow | `CICD_DIAGNOSIS_FLOW_ID` |
+| Google Gemini | Powers LLM reasoning (configured in Lamatic) | Stored in Lamatic, never in the app |
+
+## Environment Setup
+
+| Variable | Required | Source | Purpose |
+|---|:---:|---|---|
+| `LAMATIC_API_KEY` | Yes | Lamatic Settings → API Keys | Authenticates server-side flow execution |
+| `LAMATIC_PROJECT_ID` | Yes | Lamatic project settings | Identifies the deployed project |
+| `LAMATIC_API_URL` | Yes | Lamatic API Docs | Base endpoint for the project runtime |
+| `CICD_DIAGNOSIS_FLOW_ID` | Yes | Flow menu → Copy Flow ID | Identifies the deployed diagnosis flow |
+
+## Quickstart
+
+1. Deploy the Lamatic flow (see `docs/lamatic-workflow.md` for node configuration).
+2. Copy `apps/.env.example` to `apps/.env.local`.
+3. Fill in the four required Lamatic values.
+4. Run `npm install` from the `apps/` directory.
+5. Run `npm run dev` and open `http://localhost:3000`.
+6. Upload one of the example logs from `examples/` to test the system.
+
+## Common Failure Modes
+
+| Symptom | Likely Cause | Fix |
+|---|---|---|
+| "Agent is not configured" | Missing environment variables | Compare `.env.local` with `.env.example` |
+| Authentication error (401) | Invalid or expired `LAMATIC_API_KEY` | Generate a new key in Lamatic Settings |
+| Empty diagnosis / low confidence | RAG knowledge base is not populated | Follow `docs/knowledge-architecture.md` to index documents |
+| Slow response (>45s) | Large log file hitting token limits | Reduce log to last 5,000 lines and retry |
+| Risk level always "Unknown" | Risk Reviewer node misconfigured | Verify node output schema in Lamatic Studio |
