## Summary
Brings up the Adelaide / Heidi / Addie baby shower app on ringtail k3s with the public/private split that the app's hosting contract calls for: `shower.eblu.me` (public, via Fly proxy) and `shower.ops.eblu.me` (tailnet). App is consumed as a wheel from the Forgejo PyPI index — source lives at [`adelaide-baby-shower-app`](https://forge.eblu.me/eblume/adelaide-baby-shower-app).
### What's included
- **ArgoCD app + manifests** under `argocd/manifests/shower/` (deployment, service, ProxyGroup ingress, ConfigMap for `DJANGO_DEBUG`/`DJANGO_ADMIN_URL`, ExternalSecret for `DJANGO_SECRET_KEY` from 1Password item `Shower (blumeops)`, NFS PV on sifaka, RWX media PVC, RWO local-path data PVC for SQLite). Recreate rollout because SQLite is single-writer.
- **Public surface** (`fly/`): new `shower.eblu.me` server block proxying to `shower.ops.eblu.me`. `/admin/` returns 403 at the edge except `/admin/login/` and `/admin/logout/`, which are rate-limited via a new `shower_auth` zone. `X-Clacks-Overhead` on. GNU Terry Pratchett.
- **fail2ban** filter (`shower-admin-login.conf`) matching 401/403/429 on `/admin/login/` and jail (`shower.conf`) with `maxretry=5/findtime=600/bantime=3600`. The `nginx-deny` action was generalized to take a per-jail `nginx_deny_file` so the shower has its own deny list (forge keeps using the legacy default).
- **Caddy** route on indri (`shower.ops.eblu.me` → `https://shower.tail8d86e.ts.net`).
- **Pulumi** Gandi CNAME `shower.eblu.me → blumeops-proxy.fly.dev.`.
- **Grafana** APM dashboard `configmap-shower-apm.yaml` (request rate, error rate, failed admin login count, latency percentiles, bandwidth, access logs) mirroring `docs-apm.json` with a `host="shower.eblu.me"` filter.
- **Container** `containers/shower/default.nix` — `dockerTools.buildLayeredImage` with a nixpkgs Python and a startup wrapper that creates `/app/data/.venv`, pip-installs `adelaide-baby-shower-app==1.0.0` from the forge PyPI index on first boot, runs migrations + collectstatic, and execs gunicorn. A `local_settings.py` shim pins `DATABASES.NAME`/`MEDIA_ROOT`/`STATIC_ROOT` to absolute paths so they don't end up in site-packages.
- **Docs** runbook at `docs/how-to/operations/shower-app.md` linked from the apps registry, plus changelog fragments.
### Defense layers on the public surface
1. fly nginx geo+fail2ban `$shower_banned` (per-service deny list)
2. fly nginx `limit_req zone=shower_auth` (3 r/s per Fly-Client-IP)
3. django-axes (5 fails / 1h, keyed on username+ip_address)
4. edge `/admin/` block (returns 403 for anything that isn't login/logout)
## Prerequisites for the user to do (NOT in this PR)
Halted on these per request — they touch shared/manual systems:
- [x] **NFS share** on sifaka: `/volume1/shower`, NFS rule for ringtail RW, `chown 1000:1000`
- [ ] **1Password item** `Shower (blumeops)` in the blumeops vault with a freshly minted `secret-key` field (`openssl rand -base64 48`) — do NOT reuse anything that has lived in git
- [ ] **Container build**: `mise run container-build-and-release shower`, then update `images[].newTag` in `argocd/manifests/shower/kustomization.yaml` to the resulting `v1.0.0-<sha>-nix`
- [x] **DNS**: `mise run dns-up` after merge
- [x] **Fly cert**: `fly certs add shower.eblu.me -a blumeops-proxy`
- [ ] **Caddy push**: `mise run provision-indri -- --tags caddy`
- [ ] **Fly redeploy** to pick up the new nginx block + fail2ban jail: `mise run fly-deploy`
- [ ] **ArgoCD sync**: `argocd app set shower --revision shower-app-deploy && argocd app sync shower` to test from this branch before merging
## Test plan
- [ ] Container builds successfully on nix-container-builder runner
- [ ] Pod starts, migrations run, gunicorn answers on :8000
- [ ] `kubectl --context=k3s-ringtail -n shower logs deploy/shower` clean
- [ ] `curl -sf https://shower.ops.eblu.me/` returns the splash page (tailnet)
- [ ] `curl -I -H "Host: shower.eblu.me" https://blumeops-proxy.fly.dev/` returns 200 (pre-DNS verification)
- [ ] `curl -I -H "Host: shower.eblu.me" https://blumeops-proxy.fly.dev/admin/users/` returns 403 (edge block)
- [ ] `curl -I -H "Host: shower.eblu.me" https://blumeops-proxy.fly.dev/admin/login/` returns a Django login response
- [ ] After DNS is up: `curl -I https://shower.eblu.me/` returns 200 with `X-Clacks-Overhead`
- [ ] Grafana dashboard "Shower APM" appears and starts showing traffic
- [ ] `mise run services-check` passes

Splits the nebulous gandi-operations how-to into two single-topic cards
(manage-eblu-me-dns, rotate-gandi-pat) and adds a mise task for the
recurring _acme-challenge TXT cleanup needed due to a value-comparison
bug in libdns/gandi v1.1.0 that prevents certmagic's cleanup phase from
removing presented TXT values.
The gandi reference card is updated to drop the false "different
credential from Pulumi PAT" claim — verified during the 2026-04-27
incident that Caddy and Pulumi share a single PAT.

## Summary
- **Doc review:** Reviewed `gandi-operations.md` — added `last-reviewed` frontmatter, verified all wiki-links, confirmed Pulumi state has no drift
- **Gandi reference fix:** Added missing `cv.eblu.me` CNAME row to `gandi.md` DNS records table (was present in Pulumi but undocumented)
- **Pulumi comment fix:** Updated stale `README.md` reference in `__main__.py` to point to `docs/how-to/gandi-operations.md`
- **How-to reorg:** Moved 14 how-to guides into 3 subdirectories (`deployment/`, `configuration/`, `operations/`), collapsed the Documentation and Database index sections into Configuration and Operations respectively
## Verification
- `docs-check-links` — all 180 wiki-links valid
- `docs-check-filenames` — all 90 filenames unique
- `dns-preview` — 5 resources unchanged, no drift
- All pre-commit hooks pass
## Test plan
- [ ] Verify docs site builds correctly with new paths
- [ ] Spot-check a few wiki-links from other pages to moved how-to guides

## Summary
Review session covering 3 docs, plus a codebase-wide cleanup:
### Docs reviewed
- **connect-to-postgres** — verified end-to-end (psql connection tested), stamped
- **create-release-artifact-workflow** — clarified that `build-blumeops.yaml` is only a version bump example (not a packages API example)
- **deploy-k8s-service** — fixed stale repoURL (`indri:2200` → `forge.ops.eblu.me:2222`), wrong Caddy config keys (`upstream` → `backend`, added missing `host`), updated Homepage group to "Services", added Tailscale tag documentation
### Codebase cleanup
- Migrated all remaining `op item get --fields` calls to `op read` URI syntax across 7 files (docs, READMEs, YAML comments)
- Simplified the `op read` vs `op item get` guidance in CLAUDE.md
## Side findings (not addressed)
- New `immich-pg` CNPG cluster not yet documented in the postgresql reference card
## Test plan
- [x] `psql` connection to `pg.ops.eblu.me` verified
- [x] All pre-commit hooks pass
- [x] `docs-check-links`, `docs-check-index`, `docs-check-frontmatter` pass

## Summary
- Adds a Fly.io reverse proxy (`blumeops-proxy`) that tunnels public traffic to homelab services over Tailscale
- First service exposed: `docs.eblu.me` — the Quartz static docs site
- Includes Pulumi IaC for Tailscale auth key/ACLs and Gandi DNS CNAME
- Adds mise tasks (`fly-deploy`, `fly-setup`, `fly-shutoff`) and Forgejo CI workflow
## Key details
- Fly.io Firecracker VMs support TUN devices natively — no userspace networking needed
- Tailscale auth key is `preauthorized=True` to avoid device approval hangs on container restarts
- nginx caches aggressively for the static site; health check is on the default_server block
- ACLs restrict `tag:flyio-proxy` to `tag:k8s` on port 443 only
- DNS CNAME deployed and verified: `docs.eblu.me` → `blumeops-proxy.fly.dev`
## Test plan
- [x] `curl -sf https://blumeops-proxy.fly.dev/healthz` returns `ok`
- [x] `curl -I -H "Host: docs.eblu.me" https://blumeops-proxy.fly.dev/` returns 200 with `X-Cache-Status`
- [x] `curl -I https://docs.eblu.me/` returns 200 with valid Let's Encrypt cert
- [x] `dig forge.ops.eblu.me` still resolves to 100.98.163.89 (private services unaffected)
- [x] Set `FLY_DEPLOY_TOKEN` Forgejo Actions secret for CI auto-deploy

## Summary
- Restructure Pulumi into separate projects: `pulumi/tailscale/` and `pulumi/gandi/`
- Add Gandi LiveDNS management for `eblu.me` domain
- Create wildcard DNS record `*.ops.eblu.me` → indri's Tailscale IP (100.98.163.89)
- Add mise tasks: `dns-up`, `dns-preview`
- Update `tailnet-up` to pass `--yes` by default
- Document PAT cycling process (expires every 30 days)
## Background
This enables using real DNS names (`*.ops.eblu.me`) that resolve to Tailscale IPs,
which allows containers and other systems to resolve services without depending on
MagicDNS. Since Tailscale IPs (100.x.x.x) are not publicly routable, services remain
tailnet-only while using standard DNS.
## Deployment and Testing
- [ ] Run `cd pulumi/gandi && uv sync` to install dependencies
- [ ] Run `cd pulumi/gandi && pulumi stack init eblu-me` to create stack
- [ ] Run `mise run dns-preview` to verify configuration
- [ ] Run `mise run dns-up` to apply DNS records
- [ ] Verify with `dig +short test.ops.eblu.me` returns `100.98.163.89`
