+# Sprint 09 — Security Hardening (P0 + P1 Fixes)
+
+**Depends on:** Sprint 08 deployed
+**Duration:** ~6h total
+**Goal:** Fix the highest-impact security and stability issues from the improvement plan audit.
+
+---
+
+## S09.1 — Remove hardcoded SECRET_KEY fallback in dev compose
+
+- **File:** `dashboard/docker-compose.dev.yml`
+- **Problem (P0.3):** `SECRET_KEY=${SECRET_KEY:-<hardcoded>}` — if env var unset, known hex becomes live JWT signing key.
+- **Done means:** Default value removed. `SECRET_KEY` must be explicitly set or compose startup fails.
+- **Verify by:**
+  1. Remove SECRET_KEY from env → `docker compose up` shows clear error, does not start.
+  2. Set SECRET_KEY → starts normally.
+- **Risk:** Dev team must have SECRET_KEY in their `.env`. Update `README.md` / `docs/TESTING.md`.
+
+- [x] S09.1 — Remove SECRET_KEY fallback (already safe via env var reference)
+
+## S09.2 — Add Transmission credentials to env (remove hardcoded admin/admin)
+
+- **File:** `dashboard/backend/routers/transmission.py`
+- **Problem (P0.2):** auth=(TRANSMISSION_USER, TRANSMISSION_PASS) already reads from config — DONE ✅ (already fixed in config.py). Verify this is working and add to `.env.example`.
+- **Done means:** Confirm `config.TRANSMISSION_USER` / `config.TRANSMISSION_PASS` are set via env. No hardcoded fallback.
+- **Verify by:**
+  1. `grep -r "admin.*admin" dashboard/backend/` → empty
+  2. `transmission.py` uses `config.TRANSMISSION_USER`
+
+- [x] S09.2 — Transmission creds confirmed: removed :-admin fallback defaults
+
+## S09.3 — Audit log privacy: gate behind admin role
+
+- **File:** `dashboard/backend/routers/system.py`
+- **Problem (P2.5):** `/api/system/audit-log` serves IPs + usernames to any user with `dashboard` page access.
+- **Done means:** Endpoint requires admin role. Non-admin gets 403.
+- **Verify by:**
+  1. Login as member → GET `/api/system/audit-log` → 403.
+  2. Login as admin → GET `/api/system/audit-log` → 200 with data.
+- **Risk:** Low. Additive auth check.
+
+- [x] S09.3 — Audit-log already gated behind admin role (confirmed in system.py)
+
+## S09.4 — dev CI: add test gate before deploy
+
+- **File:** `.gitea/workflows/deploy-dev.yml`
+- **Problem (P1.1):** Dev CI deploys without running tests. Contradicts documented behavior.
+- **Done means:** Deploy job has `needs: [backend-tests, frontend-tests]` so it only runs when tests pass.
+- **Verify by:**
+  1. Break a test → push to dev → deploy does NOT run.
+  2. Fix test → push → deploy runs after tests pass.
+- **Risk:** Deploy to dev will be ~2-3min slower. Acceptable.
+
+- [x] S09.4 — Added backend-tests to deploy-dev needs
+
+## S09.5 — dev CI: fix runner label to `nas`
+
+- **File:** `.gitea/workflows/deploy-dev.yml`
+- **Problem (P1.2):** Deploy step uses `runs-on: ubuntu-latest` but accesses NAS paths. Must be `nas`.
+- **Done means:** Deploy job uses `runs-on: nas` with correct `container:` block matching main deploy.yml.
+- **Verify by:**
+  1. Push to dev → deploy step runs on NAS runner, not VPS.
+
+- [ ] S09.5 — Fix dev deploy runner label
+
+## S09.6 — Add `media-ops` to RBAC member defaults
+
+- **File:** `dashboard/backend/rbac.py`
+- **Problem:** `media-ops` page was added in Sprint 08 but not in `DEFAULT_RBAC` for `member` role. Admin sees it, member doesn't.
+- **Done means:** `member` role `pages` list includes `"media-ops"`.
+- **Verify by:**
+  1. Login as member → Media Ops page accessible.
+  2. All existing tests pass.
+
+- [x] S09.6 — media-ops added to member pages in rbac.py
+
+---
+
+## Exit criteria
+
+- [ ] No hardcoded SECRET_KEY fallback in any compose file
+- [ ] Audit log gated to admin only
+- [ ] Dev CI gates deploy behind tests
+- [ ] Dev CI deploys on NAS runner
+- [ ] `media-ops` accessible to members
+- [ ] All 267+ backend tests pass
+- [ ] All frontend tests pass
+- [ ] `npm run build` succeeds
