feat(advisor): Quellenanker auch fuer strukturelle Verweise (Step A.1)

Erweitert die Korpus-Autoritaet-Regel: Kapitel/Abschnitt/Teil/Anhang nur nennen, wenn in der Quelle belegt — keine aus Struktur-/Trainingswissen ergaenzte Gliederung ("Kapitel 3 BDSG"). Grund: Prod-Grounding-Check zeigte §38/20-Personen sauber gegroundet, aber "Kapitel 3 BDSG" stand NICHT im Chunk (Modell-ergaenzt). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

-# 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>.
