feat(ai-sdk): keep cyber/AI hazards out of the traditional CE hazard log

InitializeProject created hazards for every matched pattern, so native
cybersecurity/AI topics (unauthorized access, firmware manipulation, missing
SBOM, ...) mixed into the ISO 12100 hazard log. Route the security categories
(frontend groups I. Cyber/Netzwerk + J. KI) to the CRA module instead —
generically for EVERY project, enforced centrally in InitializeProject.

The split is by the nature of the hazard, not the component: functional-safety
control faults stay in CE (software faults, lost safety functions, config
errors, bus failures, botched updates) — they are random/systematic faults,
not attacks, and feed the CRA safety-function bridge. This holds whether the
controller is a bought-in CE-marked PLC or the manufacturer's own control.

+# Infisical Setup for Local Development
+
+This is the per-developer onboarding for accessing the `breakpilot-compliance` secrets while developing locally. Once this is done, **everything you launch through `make dev` (or `infisical run …`) gets the dev secrets injected as environment variables** — including any Claude Code session that spawns those commands.
+
+Secrets live in the self-hosted Infisical instance at **`secrets.meghsakha.com`**. The project link is committed in `.infisical.json`, so you don't need to know the project ID.
+
+---
+
+## 1. Install the Infisical CLI
+
+**macOS (recommended):**
+
+```bash
+brew install infisical/get-cli/infisical
+```
+
+**Other platforms / manual install:**
+
+See <https://infisical.com/docs/cli/overview>. Verify with:
+
+```bash
+infisical --version
+# infisical version 0.43.x (or newer)
+```
+
+---
+
+## 2. Log in to the self-hosted instance
+
+```bash
+infisical login --domain https://secrets.meghsakha.com
+```
+
+This opens a browser for SSO. The login is persisted to your OS keychain — you only do this once per machine.
+
+Sanity check:
+
+```bash
+cd ~/projects/breakpilot-compliance   # wherever you cloned the repo
+infisical --domain https://secrets.meghsakha.com secrets --env=dev
+```
+
+You should see a table of secret names + values. If you get an auth error, re-run `infisical login`.
+
+---
+
+## 3. Verify the project link
+
+The repo already contains `.infisical.json` pointing at the `breakpilot-compliance` project:
+
+```bash
+cat .infisical.json
+# { "workspaceId": "996bda36-9e01-4071-ae8d-69a9f9ff5a23", ... }
+```
+
+If the file is missing (rare — only if you reset the repo), recreate it:
+
+```bash
+infisical init --domain https://secrets.meghsakha.com
+```
+
+Pick the `breakpilot-compliance` project from the picker.
+
+---
+
+## 4. Launch the stack
+
+```bash
+make dev
+```
+
+This runs `infisical run --env=dev -- docker compose up`. Every service in the compose stack sees its secrets as normal env vars — no `.env` file ever touches disk.
+
+Other targets:
+
+| Target | What it does |
+|--------|--------------|
+| `make dev-build` | Same as `make dev` but rebuilds images first |
+| `make dev-down` | Stop the stack (no secrets needed) |
+| `make dev-logs` | Tail logs |
+| `make dev-ps` | List running containers |
+| `make secrets` | Print all secrets in `dev` (read-only) |
+| `make secrets-set KEY=FOO VALUE=bar` | Add or update a secret in `dev` |
+
+To target a different environment:
+
+```bash
+make dev ENV=staging
+make secrets ENV=prod
+```
+
+---
+
+## 5. Using secrets from Claude Code
+
+When Claude Code runs commands in this repo via its Bash tool, the commands inherit your shell's environment. Two patterns:
+
+**Pattern A — let Claude launch the stack normally**
+
+Claude just runs `make dev`. The Infisical CLI inside that command resolves secrets at run time and passes them to docker compose. Claude doesn't see plaintext secrets in its context, but the running services do.
+
+**Pattern B — let Claude run a one-off script with secrets**
+
+If Claude needs to execute a Python/Go script that requires secrets, wrap the command:
+
+```bash
+infisical run --env=dev -- python scripts/some_one_off.py
+```
+
+This works for any subprocess: pytest, alembic, go run, npm scripts. If Claude proposes a command that reads env vars and runs raw, ask it to wrap it in `infisical run --env=dev --` first.
+
+**What Claude should not do:**
+
+- `infisical export --env=dev > .env` — defeats the whole point and the `.gitignore` will still try to keep the file out.
+- `infisical secrets get KEY --env=dev --raw` and pasting the value into a code edit — secrets must stay out of the repo.
+
+If you want Claude to never accidentally dump secrets, add this to your `.claude/settings.json` permissions (project-level or user-level):
+
+```json
+{
+  "permissions": {
+    "deny": [
+      "Bash(infisical export*)",
+      "Bash(infisical secrets get*)"
+    ]
+  }
+}
+```
+
+---
+
+## Troubleshooting
+
+| Symptom | Fix |
+|---------|-----|
+| `please either run infisical init or pass --projectId` | `.infisical.json` is missing or unreadable — re-run `infisical init` |
+| `unauthorized` / `please log in` | Re-run `infisical login --domain https://secrets.meghsakha.com` |
+| `make dev` says secret is empty | Check the name in `make secrets` matches what docker-compose expects, then update the service config or rename the secret in Infisical |
+| Browser SSO doesn't open | Use `infisical login --domain https://secrets.meghsakha.com --method=user` and paste the URL manually |
+
+---
+
+## What the dev env contains
+
+Run `make secrets` to see the live list. As of this writing the dev env includes (at minimum):
+
+- `BREAKPILOT_DB_PASSWORD`
+- `BREAKPILOT_QDRANT_API_KEY`
+- `LITELLM_API_KEY`
+
+Every other variable in `.env.example` either has a sane default in `docker-compose.yml` or needs to be added to Infisical. To add one:
+
+```bash
+make secrets-set KEY=ANTHROPIC_API_KEY VALUE=sk-ant-xxxx
+```
+
+Or via the web UI: <https://secrets.meghsakha.com>.
