## Why repospawner v0.1.0 is built and its Vault kubernetes auth role is applied, but nothing deploys it. It turns a "I want a new repository" request into a terraform-git pull request, follows that PR to merge, and optionally activates the repo in Woodpecker, so the review gate stays where it is instead of moving into an agent's hands. ## How - Add `apps/base/repospawner/`: namespace, ServiceAccount `repospawner`, `default` VaultAuth for VSO, and a namespaced Role/RoleBinding granting jobs create/get/list/watch/delete plus pods and pods/log reads (mirrors mediamover). - Deployment pinned to `artifactapi.k8s.syd1.au.unkin.net/docker-internal/repospawner:v0.1.0`, one replica with the `Recreate` strategy because request state is in memory and rebuilt from Job labels; the same image reference is passed down as `REPOSPAWNER_IMAGE` so the spawned Jobs stay in step. - Mount a projected `audience: vault` service account token at `/var/run/secrets/vault` — the app logs into Vault natively rather than through VSO — and the `repospawner-woodpecker` Secret at `/etc/repospawner/woodpecker`, optional so the server still starts and refuses `woodpecker: true` with 503 when it is absent. - Two VaultStaticSecrets: `oauth-credentials` from `kv/kubernetes/namespace/repospawner/default/oauth-credentials` and `repospawner-woodpecker` (key `token`) from `.../default/woodpecker`, with reloader annotations on both consumers. - oauth2-proxy front door on the watchstate/mediamark pattern, gated on `akP-repospawner-admin` via the `ak_groups` claim and re-checked by the app from `X-Forwarded-Groups`; public `repospawner.unkin.net` on the reflected wildcard and internal `repospawner.k8s.syd1.au.unkin.net` on `vault-issuer`, both routed to the oauth2 Service. - Register the overlay in the platform ApplicationSet and AppProject, and append `repospawner` to the wildcard Certificate's two reflector namespace lists. Depends on the terraform-authentik `repospawner` client being applied and `kv/kubernetes/namespace/repospawner/default/oauth-credentials` + `.../woodpecker` being seeded.
