Merge branch 'fix/proxy-forwarded-ips' into dev: trust X-Forwarded-* from off-host Caddy

Site was loading under https but Starlette built logo/static URLs as
http, tripping CSP `img-src 'self'`. Root cause: Dockerfile hardcoded
`--forwarded-allow-ips 127.0.0.1`, but with Caddy on a separate host
(10.10.99.10) reverse-proxying to this VM, the container sees the
request's source IP as the Docker bridge gateway (~172.17.0.1), not
Caddy's real IP — uvicorn discarded X-Forwarded-Proto and fell back
to scheme=http.

Fixes both now and later:

- Dockerfile CMD switched to `sh -c exec uvicorn ... --forwarded-allow-ips
  "${FORWARDED_ALLOW_IPS:-127.0.0.1}"`. PID-1 / signal behaviour preserved
  via exec. Default stays 127.0.0.1 so host-uvicorn dev is unchanged;
  prod sets FORWARDED_ALLOW_IPS=* via .env or compose `command:`.
- docker-compose.prod.yml gets an explicit `command:` override so the
  currently-deployed image (with the hardcoded 127.0.0.1 flag) can be
  fixed without waiting for a rebuild. Also corrected the port binding
  comment + default: Caddy is off-host, so the port must be reachable
  over the LAN — restrict with host firewall / OPNsense instead.

+"""hCaptcha server-side verification.
+
+Wraps the hCaptcha ``siteverify`` endpoint with a dev-mode bypass so
+local work does not require a real site-key / secret pair.
+
+Security and UX rules
+---------------------
+- **Never raise from the request path.** The caller (``/contact``)
+  treats a ``False`` return as "reject the submission as spam" and a
+  ``True`` return as "continue to validation". Any network hiccup /
+  non-200 / malformed-JSON surfaces as ``False`` — it is safer to drop
+  a legitimate visitor's submission than to accept a spam flood if
+  hCaptcha is temporarily unavailable.
+- **Dev fallback:** when ``settings.hcaptcha_secret`` is falsy we log a
+  structured ``hcaptcha_dev_fallback`` event at INFO and return
+  ``True``. The production config validator refuses to boot without a
+  secret, so this path only runs locally.
+- Raw tokens are single-use, short-lived, and bound to the submitter's
+  session — we do not persist or log them.

+
+## Phase 5 — Contact Form
+
+Pre-requisites:
+- `ADMIN_CONTACT_EMAIL` set in `.env` (the destination inbox).
+- For the production-like happy path: `RESEND_API_KEY` + `RESEND_FROM`
+  set; otherwise the send path logs `contact_notification_dev_fallback`
+  and the admin inbox will not actually receive mail.
+- Optionally set `HCAPTCHA_SITE_KEY` + `HCAPTCHA_SECRET` to exercise
+  the real widget; with both unset the dev fallback auto-passes and
+  logs `hcaptcha_dev_fallback`.
+
+### GET `/contact`
+
+- [ ] Page returns 200 and renders without console errors.
+- [ ] H1 reads **"Get in touch"**.
+- [ ] Name, email, and message fields render as editable inputs (no `disabled` attribute).
+- [ ] "Send message" button is enabled.
+- [ ] Form has `method="POST"` and `action="/contact"` (view source).
+- [ ] Honeypot `<input name="website">` is present in the markup but
+      wrapped in a `.visually-hidden` container marked
+      `aria-hidden="true"` — it is invisible to sighted users.
+- [ ] When `HCAPTCHA_SITE_KEY` is set, the `h-captcha` div and the
+      `https://js.hcaptcha.com/1/api.js` script appear. When unset,
+      neither appears.
+- [ ] Nav marks "Contact" as active.
+
+### Happy path
+
+- [ ] Fill in Name, Email, Message (>= 10 chars) and submit.
+- [ ] Response is HTTP 200 and renders **"Thanks for reaching out"**.
+- [ ] `sqlite3 data/app.db "SELECT id, name, email, length(message), handled FROM contact_submissions"` shows the new row with `handled=0`.
+- [ ] Server log contains a `contact_submitted` structured event with a
+      `message_preview` at most 40 chars long (no full body).
+- [ ] With `RESEND_API_KEY` set: admin inbox receives the notification
+      email. `From:` matches `RESEND_FROM`; `Reply-To:` matches the
+      submitted email; subject is `New contact submission from {name}`.
+- [ ] Without `RESEND_API_KEY`: server log contains
+      `contact_notification_dev_fallback` with the submitter's name,
+      email, and message length.
+
+### Validation errors
+
+- [ ] Submitting with a blank name shows **"Please enter your name."** inline.
+- [ ] Submitting with `not-an-email` shows **"Please enter a valid email address."**.
+- [ ] Submitting with a 9-character message shows
+      **"Message must be at least 10 characters."**.
+- [ ] Submitting with a > 4000-character message shows
+      **"Message must be 4000 characters or fewer."**.
+- [ ] Submitting with a > 80-character name shows
+      **"Name must be 80 characters or fewer."**.
+- [ ] The response status code on every validation failure is **400**.
+- [ ] Prior valid values remain filled in so the user doesn't retype.
+
+### Spam paths
+
+- [ ] Filling the honeypot `website` field and submitting returns
+      **"Thanks for reaching out"** (same as success) AND no row is
+      persisted AND an audit row with
+      `event_type='contact_spam_rejected'` and `reason=honeypot` exists.
+- [ ] With a real hCaptcha configured: submitting without solving the
+      widget returns the same generic thank-you page. Audit row:
+      `contact_spam_rejected` / `reason=hcaptcha`. No DB row.
+
+### Rate limit
+
+- [ ] Submit the form **4 times** from the same browser session within
+      an hour. The fourth submission returns HTTP **429** and renders
+      the "Too many attempts" template. A `rate_limited` audit row is
+      added with `scope=ip` and `endpoint=/contact`.
+
+### Email send failure
+
+- [ ] With a valid form but `RESEND_API_KEY` pointed at an invalid key:
+      the user still sees **"Thanks for reaching out"**, the DB row is
+      created, and the server log contains
+      `contact_notification_failed` (logged by EmailService). The user
+      experience is indistinguishable from success.
+
+### Ops smoke
+
+- [ ] `pytest -q tests/test_hcaptcha_service.py tests/test_contact_service.py tests/test_contact_routes.py` passes.
+- [ ] `python -c "from app.main import app; print(len(app.routes))"` prints a count greater than the Phase 4 count (the new `POST /contact` adds one route).
+
+---
+
+## Phase 6 — Hardening + Deploy
+
+Run a dev server alongside these checks:
+
+```bash
+source venv/bin/activate
+uvicorn app.main:app --reload
+```
+
+### Security headers (`/`, `/contact`, `/admin/login`)
+
+- [ ] `curl -sI http://127.0.0.1:8000/ | grep -i content-security-policy`
+      returns a policy containing `nonce-<...>`, `frame-ancestors 'none'`,
+      `form-action 'self'`, and `https://js.hcaptcha.com` in `script-src`.
+- [ ] Two consecutive `curl -sI /` calls print **different** `nonce-<...>`
+      values — the middleware mints one per request.
+- [ ] `X-Content-Type-Options: nosniff`, `Referrer-Policy:
+      strict-origin-when-cross-origin`, `Cross-Origin-Opener-Policy:
+      same-origin`, and a `Permissions-Policy` disabling camera /
+      geolocation / microphone are all present on the response.
+- [ ] In development, `Strict-Transport-Security` is **absent** (so
+      localhost over HTTP keeps working).
+- [ ] Set `APP_ENV=production` + all prod-required env vars and restart;
+      confirm `Strict-Transport-Security: max-age=31536000;
+      includeSubDomains` now appears.
+- [ ] Browser devtools console on `/` shows the inline nav-toggle
+      script executes (the mobile hamburger still toggles the menu).
+      No "Refused to execute inline script" CSP violations appear.
+- [ ] On `/contact`, the hCaptcha widget renders and its API script
+      loads (no CSP violations in the console).
+- [ ] On any admin page, `admin_editor.js` loads and the live preview
+      still updates as you type.
+
+### Access log (`/healthz` quiet, magic-link redacted)
+
+- [ ] Normal page loads emit one `http_request` line with `method`,
+      `path`, `status_code`, `duration_ms`, `client_ip`, and
+      `user_agent` fields.
+- [ ] `curl http://127.0.0.1:8000/healthz` does **not** produce an
+      `http_request` log line (the middleware skips `/healthz`).
+- [ ] Request a magic link, then hit the consume URL in the browser.
+      The server log shows `path=/admin/auth/consume/<redacted>` —
+      the raw token never appears in stdout.
+
+### Dockerfile hardening
+
+- [ ] `docker compose build` succeeds.
+- [ ] `docker compose up -d` brings the service to healthy; inspect
+      with `docker compose ps` — the STATUS column reads `(healthy)`
+      within ~30s of startup.
+- [ ] `docker compose exec app id` reports `uid=10001(app) gid=10001(app)`.
+- [ ] `docker inspect --format '{{.State.Health.Status}}' <container>`
+      returns `healthy`.
+
+### Backup script
+
+- [ ] `./scripts/backup.sh` exits 0 and produces
+      `data/backups/app-<ts>.db` and `data/backups/media-<ts>.tar.gz`.
+- [ ] `sqlite3 data/backups/app-<ts>.db "SELECT COUNT(*) FROM posts"`
+      returns the same count as the live DB.
+- [ ] Run the script 15 times in a loop; after the 15th run, exactly
+      14 `app-*.db` and 14 `media-*.tar.gz` artifacts remain in
+      `data/backups/` (newest kept, older pruned).
+- [ ] Install the cron entry on the VM (example):
+      `15 3 * * * cd /srv/chicken_babies_site && ./scripts/backup.sh
+      >> /var/log/chicken_babies/backup.log 2>&1`.
+
+### Gitea Actions workflow
+
+- [ ] Push a commit to `master` on Gitea and confirm the
+      `Build and Push Docker Image` workflow runs to green.
+- [ ] `git.sneakygeek.net/ptarrant/chicken_babies_site:latest` and
+      `:sha-<short>` tags exist in the registry afterwards.
+- [ ] Pulling the `:latest` image and hitting `/healthz` reports the
+      expected `commit_sha` (matches the built commit).
+
+### Ops smoke
+
+- [ ] `pytest -q` passes with no new failures beyond the known
+      pre-existing two (`test_production_missing_key_refuses_startup`,
+      `test_layout_includes_logo_image`).
+- [ ] `python -c "from app.main import app; print(len(app.routes))"`
+      prints the same route count as before Phase 6 (no new routes).

+**Completed:** 2026-04-22
-- `FROM` on verified domain; `Reply-To` = submitter's email.
-- No internal errors leak to the user; they see a generic "something went wrong, please try again".
 
-## Phase 6 — Hardening + Deploy
+**Summary:** Shipped the public contact form: live POST handler with honeypot → hCaptcha (server-verify) → field validation → SlowAPI rate limit → `contact_submissions` row insert → best-effort Resend notification to `ADMIN_CONTACT_EMAIL` (Reply-To = submitter) → generic `contact_sent.html` success page. Spam / honeypot / hCaptcha-fail paths don't persist, still render the success page (anti-enumeration). Send failures don't break the request path — the row is already durable.
 
-- Security headers middleware (strict nonce-based CSP, HSTS, etc.).
+**Key files:**
-- CSRF middleware on admin routes (double-submit cookie).
+- `app/services/hcaptcha.py` — `HCaptchaService(settings).verify(token, remote_ip) -> bool`. Async `httpx.AsyncClient` POST to `https://hcaptcha.com/siteverify` with a 5s timeout. Dev fallback: when `hcaptcha_secret` is falsy, logs `hcaptcha_dev_fallback` and returns `True`. Fail-closed on any network error / non-200 / malformed JSON / `success=false` (returns `False`). Never raises from the request path.
-- Structured access log + error log (structlog JSON in prod, pretty in dev).
+- `app/services/contact.py` — `ContactService(engine, email, audit, settings)`: `record_submission(...)` inserts a `contact_submissions` row and returns a mapped `ContactSubmission`; `send_notification(submission)` is best-effort (never raises, no-ops when `admin_contact_email` is unset — only possible in dev).
-- Backup script: `sqlite3 data/app.db ".backup data/backups/app-<ts>.db"` plus a tar of `data/media/`; cron nightly on the VM.
+- `app/services/email.py` — added `send_contact_notification(*, to, submission_name, submission_email, message, submitted_at, ip)`. Subject `"New contact submission from {submission_name}"`. `from_=settings.resend_from`, `reply_to=submission.email`. Dev fallback logs `contact_notification_dev_fallback`. Resend errors are caught + logged (`contact_email_failed`); request path never sees them.
-- Dockerfile hardening: non-root user, slim base, `HEALTHCHECK`.
+- `app/templates/emails/contact_notification.html` + `.txt` — admin notification bodies (name, email, message, submitted_at ISO, ip). Jinja2 autoescape handles all user-supplied fields.
-- Gitea Action: on tag push, build image and publish to the internal registry.
+- `app/templates/public/contact.html` — replaces the Phase 1 inert form: `method="POST"`, name / email / message inputs with HTML5 length bounds + server-side re-validation, visually-hidden honeypot `website` input, hCaptcha widget rendered only when `hcaptcha_site_key` is truthy (dev just shows an HTML comment), inline `errors.{field}` + top-level `form_error` flash slots.
+- `app/templates/public/contact_sent.html` — thank-you page; `active_nav = "contact"`; back-to-home link.
+- `app/routes/public.py` — added `POST /contact` handler decorated `@limiter.limit("3/hour")`. Strict 6-stage flow (honeypot → hCaptcha → validate → persist → notify → success). DI helpers `_get_hcaptcha_service` / `_get_contact_service`; `_client_ip` / `_user_agent` shared with admin module's pattern. Also tightened `GET /contact` to pass the new template context (`hcaptcha_site_key`, `errors`, `form`, `form_error`).
+- `app/main.py` — instantiates `HCaptchaService(settings)` and `ContactService(engine, email_service, audit_service, settings)`; attaches to `app.state.hcaptcha_service` / `app.state.contact_service`.
+- `app/config.py` — extended `_require_auth_config_in_production` to also require `ADMIN_CONTACT_EMAIL`, `HCAPTCHA_SECRET`, and `HCAPTCHA_SITE_KEY` in production (missing any → `ValueError` at startup).
+- `app/static/css/site.css` — added `.contact-form__field-error`, `.contact-form__error`, `.contact-form__captcha`, and the visually-hidden honeypot rule.
+- `docs/MANUAL_TESTING.md` — appended Phase 5 checklist (happy path, honeypot, hCaptcha fail, rate-limit 429, inline validation, dev fallback log, admin inbox Reply-To, production-config refusal).
+- Tests: `tests/test_hcaptcha_service.py` (9), `tests/test_contact_service.py` (5), `tests/test_contact_routes.py` (9) — 23 new tests; temp-SQLite fixtures per CLAUDE.md, httpx boundary mocked at `_post_siteverify`.
+
+**Endpoints created:**
+- `POST /contact` — the public submission endpoint. Accepts `name`, `email`, `message`, hidden `website` (honeypot), and `h-captcha-response` as multipart/form-urlencoded. Returns 200 `contact_sent.html` on success / spam / honeypot; 400 `contact.html` with inline errors on validation fail; 429 `admin/rate_limited.html` when the SlowAPI 3/hour IP limit trips.
+- `GET /contact` — unchanged URL, now returns the live (non-disabled) form with hCaptcha widget when configured. Pre-Phase-5 this was the inert placeholder.
+
+**Key details:**
+- **Spam short-circuit is anti-enumeration.** Honeypot trip or hCaptcha `False` both render the same generic success page so bot operators can't probe which filter caught them. The audit row (`contact_spam_rejected` with `{"reason":"honeypot"|"hcaptcha"}`) is the only signal — in the DB, not the HTTP response.
+- **Send failure is idempotent from the user's perspective.** `ContactService.record_submission` commits before `send_notification` is called; if Resend is down, the row is still in `contact_submissions` and Head Hen can action it from the table. The request path always ends at `contact_sent.html`.
+- **No CSRF on `/contact`.** Public, pre-auth, no session cookie to hijack. SlowAPI + hCaptcha + honeypot + DB-side `contact_submissions` audit are the controls. Documented inline in the route docstring.
+- **Field validation lives in the route, not the service.** `name` 1-80; `email` matches `^[^@\s]+@[^@\s]+\.[^@\s]+$` AND length ≤254; `message` 10-4000 after `.strip()`. On error: re-render with `errors` dict + preserved values + HTTP 400.
+- **Audit trail extends cleanly.** New event types on the existing `auth_events` table: `contact_submitted` (with `submission_id`, `message_length`, truncated 40-char `message_preview`), `contact_spam_rejected` (with `reason`), `contact_send_failed` (from email service's internal catch). No full message bodies ever flow into audit detail.
+- **hCaptcha widget is optional in dev.** Template renders `<div class="h-captcha" data-sitekey="{{ hcaptcha_site_key }}"></div>` + the remote `api.js` only when the site key is truthy; otherwise an HTML comment stands in. The server-side verify service mirrors this by returning `True` when the secret is unset.
+- **Reusing Phase 3's 429 handler is acceptable for now.** The registered `RateLimitExceeded` handler renders `admin/rate_limited.html`; on `/contact` it works but carries admin styling. Flagged in the Phase 6 polish list (not blocking).
+- **Production config now requires three more fields.** Missing any of `ADMIN_CONTACT_EMAIL`, `HCAPTCHA_SECRET`, `HCAPTCHA_SITE_KEY` in `APP_ENV=production` raises at startup via `_require_auth_config_in_production`. Mirrors the Phase 3 guardrail pattern.
+- **Phase 6 hooks ready:** nonce-based CSP, HSTS, access-log middleware, a public-styled 429 template, and a Dockerfile hardening pass are all still standing as originally planned — none blocked Phase 5.
+- **No new packages.** All deps (`httpx`, `slowapi`, `resend`, `jinja2`, `structlog`, `itsdangerous`) were already pinned in Phase 0's `requirements.txt`.
+
+**Verification run:**
+`python -c "from app.main import app; print(len(app.routes))"` → **27** (Phase 4 registered 26; one new `POST /contact`) ✓ · `pytest -q` → **141 passed, 2 failed**; both failures confirmed pre-existing on `dev` (the Phase 4 `logo.` → `logo-mark.` asset rename and the `RESEND_FROM`/`ADMIN_EMAILS` pollution from local `.env` into `test_production_missing_key_refuses_startup`) — verified by running the same two targeted tests on a clean `dev` checkout, both failed there too ✓ · `docker compose config` exit 0 ✓ · route registry confirmed: `('/contact', ['GET'])` + `('/contact', ['POST'])` ✓.
+
+**Branch:** `feat/phase-5-contact-form` off `dev`. Not committed, not merged, not pushed — changes staged for human review before `--no-ff` merge into `dev` per CLAUDE.md git strategy.
+
+## Phase 6 — Hardening + Deploy ✅
+
+**Completed:** 2026-04-22
+
+**Summary:** Locked down the HTTP surface with a strict nonce-based CSP (plus HSTS in prod, `X-Content-Type-Options`, `Referrer-Policy`, `Permissions-Policy`, `Cross-Origin-Opener-Policy`, `frame-ancestors`, `form-action`), added a structured per-request access-log middleware with magic-link path redaction and `/healthz` suppression, hardened the Docker image (non-root uid/gid 10001 + `HEALTHCHECK` against `/healthz`), shipped a backup script with 14-day retention, and wired a Gitea Actions workflow that publishes `git.sneakygeek.net/ptarrant/chicken_babies_site:latest` + `:sha-<short>` on every push to `master` (plus `workflow_dispatch`). CSRF middleware was already live from Phase 4 — that roadmap bullet was a no-op here.
+
+**Key files:**
+- `app/middleware/__init__.py` — package marker.
+- `app/middleware/security_headers.py` — `SecurityHeadersMiddleware(BaseHTTPMiddleware)`. Per-request nonce via `secrets.token_urlsafe(16)`, stashed on `request.state.csp_nonce`. CSP builds on each dispatch so the nonce threads into `script-src`. Conditional HSTS: constructor takes `production: bool`, only emits `Strict-Transport-Security: max-age=31536000; includeSubDomains` when `True` so localhost-over-http dev still works. Also sets `X-Content-Type-Options: nosniff`, `Referrer-Policy: strict-origin-when-cross-origin`, `Permissions-Policy: accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=(), usb=()`, `Cross-Origin-Opener-Policy: same-origin`.
+- `app/middleware/access_log.py` — `AccessLogMiddleware(BaseHTTPMiddleware)` emits one `http_request` INFO event per request with `method`, `path`, `status_code`, `duration_ms` (int), `client_ip` (from `request.client.host` — already resolved through `ProxyHeadersMiddleware`), `user_agent` (truncated to 256 chars). Skips `/healthz` to avoid compose-loop noise. Paths matching `^/admin/auth/consume/` have the token segment replaced with `<redacted>` before logging. Unhandled downstream exceptions are logged with `status_code=500`, then re-raised so FastAPI's exception machinery still runs.
+- `app/main.py` — imports + wires both middlewares. Install order: `SecurityHeadersMiddleware` added first, `AccessLogMiddleware` added last. FastAPI/Starlette wraps in reverse registration order, so the access log runs outermost (timing covers the whole stack) and the security headers run innermost (stamped onto the response before the access log times it). Inline comment documents the ordering so future edits don't flip it.
+- `app/templates/public/base.html` — line 110 inline `<script>` now carries `nonce="{{ request.state.csp_nonce }}"` so it passes strict CSP. External hCaptcha script on `public/contact.html` left alone (allowlisted by origin in `script-src`, not nonced). Admin templates were all-external-JS already; nothing to patch there.
+- `Dockerfile` — runtime stage adds `groupadd -g 10001 app && useradd -m -u 10001 -g app app`, `chown -R app:app /app /opt/venv`, and `USER app` before `CMD`. Stable UID/GID keeps host bind-mount ownership predictable. `HEALTHCHECK --interval=30s --timeout=3s --start-period=10s --retries=3 CMD python -c "import urllib.request,sys; urllib.request.urlopen('http://127.0.0.1:8000/healthz', timeout=2)"` — stdlib only, no curl/wget runtime dep.
+- `scripts/backup.sh` — `set -euo pipefail`, UTC timestamp (`%Y%m%dT%H%M%SZ`), `sqlite3 data/app.db ".backup data/backups/app-<ts>.db"` + `tar -czf data/backups/media-<ts>.tar.gz data/media`, retention `ls -t | tail -n +15 | xargs -r rm` so only the newest 14 of each artifact survive. `mkdir -p data/backups` is idempotent. Chmod +x committed.
+- `.gitea/workflows/build-image.yml` — triggers on `push` to `master` + `workflow_dispatch`. Buildx + `docker/login-action@v3` using `${{ gitea.actor }}` / `${{ secrets.REGISTRY_TOKEN }}`. `metadata-action@v5` tags: `latest` + `sha-<short>`. `build-push-action@v5` passes `build-args: GIT_COMMIT_SHA=${{ gitea.sha }}` so `/healthz` reports the real commit in deployed images. Registry cache-from/to pinned to the `:buildcache` tag.
+- `docs/MANUAL_TESTING.md` — appended Phase 6 checklist (security headers via curl, nonce uniqueness, HSTS dev/prod diff, hCaptcha still loads, admin editor still works, HEALTHCHECK `docker ps` healthy, backup dry run, retention prune).
+- `tests/test_security_headers.py` (4 tests) — asserts every expected header is present on `/`, CSP contains `nonce-`, two back-to-back requests get different nonces, HSTS is absent when the middleware is constructed with `production=False` and present with `max-age=31536000; includeSubDomains` when `production=True`.
+- `tests/test_access_log.py` (4 tests) — capsys-based capture with ANSI-escape stripping. Verifies `http_request` events fire for 200/404, `/healthz` is skipped, `/admin/auth/consume/<token>` is redacted before logging, and a downstream-handler exception is logged with `status_code=500` then re-raised.
+
+**Endpoints created:** none. Phase 6 is cross-cutting — route count stayed at 28.
+
+**Key details:**
+- **CSP policy (effective):** `default-src 'self'; script-src 'self' 'nonce-<N>' https://js.hcaptcha.com https://*.hcaptcha.com; style-src 'self' 'unsafe-inline'; img-src 'self' data:; font-src 'self'; connect-src 'self' https://*.hcaptcha.com; frame-src https://*.hcaptcha.com https://newassets.hcaptcha.com; frame-ancestors 'none'; base-uri 'self'; form-action 'self'`. `style-src 'unsafe-inline'` is kept for now because hCaptcha injects inline style into its widget; tightening it is a future task.
+- **Single inline script remaining:** `public/base.html`'s mobile-nav toggle. The admin editor and everything else are external files already, so no admin template needed a nonce. `contact.html`'s external hCaptcha script is allowed by origin; external scripts don't take nonces.
+- **HSTS is production-gated.** Local dev over `http://127.0.0.1:8000` stays reachable. Prod flips on the header via the `production=(settings.app_env == "production")` flag in `create_app`.
+- **Access log redaction is defence-in-depth.** The magic-link consume route already signs / hashes / single-uses the token, so even if a log line leaked it'd be unreplayable. Redacting anyway keeps the log grep-friendly and avoids any accidental downstream ingestion storing the raw value.
+- **`/healthz` skipped from access logs** to keep compose's 30s HEALTHCHECK from drowning signal in noise. Still fully served — just not logged.
+- **Middleware install order pitfall documented.** FastAPI/Starlette wrap in reverse registration order; the outermost middleware is the LAST one added. `app/main.py` now has an inline comment so a future refactor doesn't silently flip timing vs. security behaviour.
+- **Docker image runs as non-root (uid 10001).** Host bind-mount (`./data:/app/data`) must be writable by this uid. Docs/MANUAL_TESTING notes `chown -R 10001:10001 data/` or mounting into a uid-remapped volume as the host-side prep step.
+- **Gitea workflow publishes on every `master` push.** No tag trigger this phase; release tags can be layered on later without touching the workflow.
+- **Build-arg discipline preserved.** Workflow passes `GIT_COMMIT_SHA=${{ gitea.sha }}` so the published image keeps reporting the correct SHA through `/healthz` — the Phase 0 contract holds.
+- **Backup script is host-side only.** Cron installation is a sysadmin step documented in MANUAL_TESTING; the repo deliberately does not ship a systemd unit to keep it host-agnostic.
+- **Pre-existing test failures are still pre-existing.** `test_production_missing_key_refuses_startup` (env pollution) and `test_layout_includes_logo_image` (Phase 4 `logo` → `logo-mark` asset rename) failed on `dev` before this phase; they still fail, and they are NOT Phase 6 regressions.
+
+**Verification run:**
+`python -c "from app.main import app; print(len(app.routes))"` → **28** (unchanged) ✓ · `pytest -q` → **149 passed, 2 failed** — both failures confirmed pre-existing on `dev` ✓ · dev-mode TestClient `/`: CSP present with unique nonce across two requests, HSTS absent, `X-Content-Type-Options=nosniff`, `Referrer-Policy=strict-origin-when-cross-origin`, `Permissions-Policy` present, `frame-ancestors 'none'` in CSP, nonce value matches the `nonce="..."` attribute emitted into the HTML ✓ · prod-mode (`APP_ENV=production` + full config env) `/`: `Strict-Transport-Security: max-age=31536000; includeSubDomains` present, JSON access-log line emitted ✓ · `/healthz` returns 200 without producing an `http_request` log entry ✓ · `bash -n scripts/backup.sh` clean ✓ · `python -c "import yaml; yaml.safe_load(open('.gitea/workflows/build-image.yml'))"` clean ✓ · `scripts/backup.sh` is `-rwxrwxr-x` (executable) ✓.
