Removes DHCP lease renewal as a failure mode on ringtail after an outage
on 2026-05-12 where the IP and routes silently disappeared from enp5s0
without any kernel link event. NetworkManager stays enabled for wireless
fallback but no longer manages the wired interface.

## Summary
- Add `nixpkgs-services` flake input pinned to a specific nixpkgs commit, with an overlay that pulls `forgejo-runner`, `snowflake`, and `k3s` from it instead of the rolling `nixpkgs`
- Dagger `flake-update` pipeline now excludes `nixpkgs-services` via `--exclude`
- Fix stale nix-container-builder version in service-versions.yaml (was 12.6.4, actually running 12.7.2)
- Add k3s and minikube to service-versions.yaml tracking
- Document the pinning approach in review-services how-to and ringtail reference
## Motivation
During service review, discovered that flake updates had silently upgraded forgejo-runner from 12.6.4 → 12.7.2 without updating service-versions.yaml. This "sneak-in upgrade" bypasses the service review process. The overlay ensures these three services only change versions deliberately.
## Test plan
- [ ] Verify `nix flake update` from `nixos/ringtail/` does not change `nixpkgs-services` lock entry
- [ ] Verify `mise run provision-ringtail` builds successfully with the overlay
- [ ] Confirm running service versions unchanged after deploy

## Summary
- Add Snowflake proxy as a native systemd service on ringtail (NixOS)
- Uses `pkgs.snowflake` from nixpkgs (v2.11.0)
- Hardened systemd unit with DynamicUser, ProtectSystem=strict, 512MB memory limit
- Prometheus metrics enabled on localhost:9999
## What is Snowflake?
A Tor pluggable transport that helps censored users reach the Tor network via WebRTC. **This is NOT a Tor exit node** — traffic exits through Tor exit nodes operated by others. The proxy operator cannot see traffic content (double-encrypted) and destination servers never see the proxy's IP.
## Changes
- `nixos/ringtail/configuration.nix` — new systemd service definition
- `docs/reference/services/snowflake-proxy.md` — service reference card
- `docs/reference/infrastructure/ringtail.md` — updated systemd services section
- `service-versions.yaml` — added entry (type: nixos)
## Deploy plan
After review, deploy via `mise run provision-ringtail`. Service starts automatically.
## Test plan
- [ ] `mise run provision-ringtail` succeeds
- [ ] `ssh ringtail 'systemctl status snowflake-proxy'` shows active
- [ ] `ssh ringtail 'journalctl -u snowflake-proxy --no-pager -n 20'` shows broker connections
- [ ] `ssh ringtail 'curl -s localhost:9999/metrics'` returns Prometheus metrics

## Summary
- Add `dagger` to `hostPackages` for the ringtail nix-container-builder runner
- Needed for `dagger call nix-version` fallback in the nix build workflow (authentik)
- `hostPackages` is scoped to the runner's systemd unit PATH, not system-wide
- Marks `install-dagger-on-nix-runner` Mikado card complete
## Deployment and Testing
- [ ] Merge, then `mise run provision-ringtail`
- [ ] `mise run container-build-and-release authentik` to verify nix build succeeds

## Summary
C2 Mikado chain for deploying Authentik as the SSO identity provider, replacing Dex.
This PR will evolve over multiple sessions. Each iteration adds documentation (prerequisite cards) and eventually code as leaf nodes are resolved.
## Current Mikado State
- **Goal:** `deploy-authentik` (active)
- **Leaf prerequisites:**
- `build-authentik-container` — Build Nix container image
- `provision-authentik-database` — Create PostgreSQL database on CNPG cluster
- `create-authentik-secrets` — Create 1Password item with credentials
## Process refinements
- Updated agent-change-process with lessons from first attempt: reset code before committing cards, open PRs early
## Test plan
- [ ] `mise run docs-mikado` shows correct dependency chain
- [ ] Leaf nodes can be worked independently
- [ ] Container builds on ringtail
- [ ] Authentik starts and reaches healthy state
- [ ] Forgejo OAuth2 connector works

## Summary
- Create Dex reference card (`docs/reference/services/dex.md`) with quick reference, architecture, identity source, storage, OIDC clients, secrets, and endpoints
- Write federated login explanation article (`docs/explanation/federated-login.md`) covering the Dex + Forgejo two-layer auth model, login flow, and break-glass access
- Add Dex to `services-check` (HTTP health endpoint + k3s pod check)
- Update Grafana docs with new Authentication section documenting SSO via Dex
- Update Forgejo docs with OAuth2 Provider section documenting its role as upstream identity source
- Add Dex to ringtail workloads table and reference service index
- Move `adopt-oidc-provider` plan to `completed/` with final design reflecting actual implementation
## Test plan
- [ ] `mise run services-check` passes (includes new Dex checks)
- [ ] `docs-check-links` passes (all wiki-links resolve)
- [ ] `docs-check-index` passes (new docs are indexed)

## Summary
- Add `containers/nettest/default.nix` using `dockerTools.buildLayeredImage` with curl, jq, dnsutils, cacert, and bash — equivalent to the existing Dockerfile
- Update `container-tag-and-release` to require `--nix` or `--dockerfile` flag when both build types exist for a container
- Update `container-list` to show `[dockerfile+nix]` label when both exist
## Deployment and Testing
- [ ] SSH to ringtail, run `nix build -f containers/nettest/default.nix -o result` to verify the nix expression builds
- [ ] Tag `nettest-nix-v1.0.0`, confirm `build-container-nix` workflow runs on `nix-container-builder` runner and pushes to registry
- [ ] Smoke test on ringtail k3s: `kubectl run nettest --image=registry.ops.eblu.me/blumeops/nettest:v1.0.0 --restart=Never && kubectl logs nettest`
- [ ] Verify `mise run container-list` shows `[dockerfile+nix]` for nettest
- [ ] Verify `mise run container-tag-and-release nettest v1.1.0` prompts for build type

## Summary
Extends ringtail from a desktop/gaming NixOS box into an infrastructure node with a k3s cluster, secrets management, and a Forgejo Actions
runner for building containers with Nix.
### K3s cluster
- Single-node k3s with Traefik/ServiceLB/metrics-server disabled (minimal footprint)
- TLS SAN set to `ringtail.tail8d86e.ts.net` so ArgoCD on indri can manage it via Tailscale
- Containerd registry mirrors pull through Zot on indri (`k3s-registries.yaml`)
- Tailscale interface added to `trustedInterfaces` for cross-node ArgoCD access
- `kubectl` added to system packages
### 1Password Connect + External Secrets Operator
- Four new ArgoCD apps targeting `k3s-ringtail`: `1password-connect-ringtail`, `external-secrets-crds-ringtail`, `external-secrets-ringtail`,
`external-secrets-config-ringtail`
- Reuses the same Helm charts/values as indri, just pointed at ringtail's k3s API server
- Bootstrap secrets (`op-credentials`, `onepassword-token`) provisioned by Ansible pre_tasks via `op read`, then applied to the `1password`
namespace in post_tasks
### Systemd Forgejo Actions runner
- Native `services.gitea-actions-runner` with `forgejo-runner` package — no DinD, no k8s pod, runs directly on the NixOS host
- Label `nix-container-builder:host` — jobs execute on the host with `nix`, `skopeo`, `nodejs`, etc. in PATH
- Registration token fetched from 1Password (`Forgejo Secrets/runner_reg`) by Ansible and written to `/etc/forgejo-runner/token.env`
- Runner's dynamic user (`gitea-runner`) added to `nix.settings.trusted-users` for nix daemon access
### Nix container build workflow
- New `.forgejo/workflows/build-container-nix.yaml` triggers on `*-nix-v[0-9]*` tags (e.g. `nettest-nix-v1.0.0`)
- Builds with `nix build -f containers/<name>/default.nix`, pushes to Zot via `skopeo copy`
- Existing Dockerfile workflow guarded with `if: !contains(github.ref_name, '-nix-v')` to avoid double-triggering
### Mise task updates
- `container-tag-and-release` auto-detects `default.nix` vs `Dockerfile` and uses the appropriate tag format (`-nix-v` vs `-v`)
- `container-list` shows build type indicator (`[nix]` / `[dockerfile]`)
## Post-merge
1. `mise run provision-ringtail` — deploys k3s token, runner token, NixOS rebuild
2. Register k3s cluster in ArgoCD (first time only):
```fish
ssh ringtail 'sudo cat /etc/rancher/k3s/k3s.yaml' | \
sed 's|127.0.0.1|ringtail.tail8d86e.ts.net|' > /tmp/k3s-ringtail.yaml
set -x KUBECONFIG /tmp/k3s-ringtail.yaml
argocd cluster add default --name k3s-ringtail
3. Sync ArgoCD apps in order: 1password-connect-ringtail -> external-secrets-crds-ringtail -> external-secrets-ringtail ->
external-secrets-config-ringtail
4. Verify runner: ssh ringtail 'systemctl status gitea-runner-nix-container-builder'
5. Check Forgejo admin panel for ringtail-nix-builder runner online
6. Test: create containers/<name>/default.nix, tag with <name>-nix-v0.1.0
