## Summary
- Enable OIDC + API key authentication on zot registry with three-tier accessControl
- `anonymousPolicy: ["read"]` — anyone can pull
- `artifact-workloads` group: `["read", "create"]` — CI push, no overwrite/delete
- `admins` group: `["read", "create", "update", "delete"]` — break-glass
- Wire both CI push paths (Dagger and Nix/skopeo) with `ZOT_CI_API_KEY` credentials
- Add `artifact-workloads` PolicyBinding in Authentik blueprint for zot app access
- Add `ZOT_CI_API_KEY` to Forgejo Actions secrets via existing ansible role
Completes the `wire-ci-registry-auth` and `harden-zot-registry` Mikado cards.
## Manual Deployment Steps (after merge)
1. Deploy Authentik blueprint: `argocd app sync authentik`
2. In Authentik admin UI: set a password for the `zot-ci` service account
3. Deploy zot config: `mise run provision-indri -- --tags zot`
4. Log in to `https://registry.ops.eblu.me` as `zot-ci` via OIDC → generate API key
5. Store API key in 1Password as `zot-ci-apikey` in blumeops vault
6. Sync Forgejo secrets: `mise run provision-indri -- --tags forgejo_actions_secrets`
7. Trigger a test container build to verify CI push
8. Verify anonymous pull: `curl -sf https://registry.ops.eblu.me/v2/_catalog`
## Uncertainties
- **Zot `accessControl` group matching with OIDC:** Groups from Authentik's `profile` scope claim should map to zot policy groups, but the exact claim-to-group matching needs runtime verification
- **`http.auth.apikey: true`:** This config key is documented but needs verification against the specific zot version built from source on indri
- **API key permissions:** Need to confirm zot API keys inherit the generating user's group for accessControl evaluation
## Test Plan
- [ ] `mise run provision-indri -- --check --diff --tags zot` shows expected config changes
- [ ] Anonymous pull works after deploy
- [ ] Unauthenticated push fails (401)
- [ ] OIDC browser login redirects to Authentik and back
- [ ] API key push works after key generation
- [ ] CI push succeeds with both Dagger and skopeo paths
- [ ] `mise run services-check` passes

## Summary
- Add Authentik blueprint (`zot.yaml`) with OAuth2 provider, application, `artifact-workloads` group, and `zot-ci` service account
- Wire `zot-client-secret` through ExternalSecret → worker Deployment env var → blueprint `!Env`
- Add Ansible pre_task to fetch OIDC secret from 1Password (item ID `oor7os5kapczgpbwv7obkca4y4`)
- Add `oidc-credentials.json.j2` template and deploy task in zot role (with `when` guard)
## Manual Steps Required Before Deploy
1. Generate client secret: `openssl rand -hex 32`
2. Store in 1Password: add field `zot-client-secret` to "Authentik (blumeops)" item in vault `blumeops`
## What This Does NOT Do
- Does NOT modify `config.json.j2` (that's the root goal `harden-zot-registry`)
- Does NOT wire CI auth (that's `wire-ci-registry-auth`)
- Does NOT set service account password or API keys (manual post-deploy)
## Verification
After ArgoCD sync:
- [ ] Authentik admin UI shows "Zot Registry" application
- [ ] OIDC discovery at `https://authentik.ops.eblu.me/application/o/zot/.well-known/openid-configuration` returns valid JSON
- [ ] Blueprint status is `successful`
- [ ] `artifact-workloads` group exists with `zot-ci` service account

## 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
