Activity Core repo-manager Forgejo read lane (CCR-2026-0034, number to confirm)

Status: proposed, drafted 2026-10-04 for STATE-WP-0094 memo 3 (freshness-runner-deploy-trial-e77f8b4, accepted by the founder 2026-10-04, approval 4ae04c8e) and RMGR-WP-0020-T04. Nothing here is approved, applied or provisioned. No Forgejo, OpenBao or cluster object was created. Confirm the CCR number with the CCR tooling before registering; 0033 was the highest seen.

Why

The bounded freshness runner (rmgr freshness run, repo-manager e77f8b4) runs inside the Activity Core worker (activity-core/actcore-worker). It reads each repository's default-branch HEAD through the Forgejo API at forgejo.coulomb.social/coulomb/<slug>. Anonymous reads fail on private repositories, which the runner records as a refusal and which stops the memo 3 trials. warden route find (2026-10-04) has no route for this workload:

• state-hub-forge-derivation-read is bound to SA state-hub/state-hub only.
• core-hub-forgejo-source-read (CCR-2026-0031) and policy-nexus-forgejo-source-read (CCR-2026-0014) are bound to other namespaces.

Reusing any of them would share one identity across workloads, which the CCR-2026-0014 and CCR-2026-0031 precedent avoids. This lane gives the runner its own read-only identity.

Shape

Item	Value
Forgejo user	activity-core-freshness (restricted, non-admin, private; random unrecorded password)
Forgejo team	coulomb/activity-core-freshness-readers: permission read, all repositories, repo.code read, every other unit none, cannot create repos
PAT	activity-core-freshness-read-<UTC timestamp>, scope exactly read:repository
OpenBao	platform/workloads/activity-core/repo-manager-forgejo-read fields FORGEJO_READ_TOKEN, API_USER, API_BASE_URL, TOKEN_SCOPES, GENERATED_AT
Policy	workload-kv-read-activity-core-repo-manager-forgejo (read on data + metadata of that one path)
Auth	Kubernetes role external-secrets-activity-core-repo-manager-forgejo, bound to SA external-secrets/external-secrets, TTL 15m
Delivery	ExternalSecret activity-core/actcore-repo-manager-forgejo-read → separate Secret, key FORGEJO_READ_TOKEN. Never merged into actcore-runtime-secret, so the token is not in the worker env
Consumer	worker mounts the Secret read-only at /var/run/secrets/repo-manager (defaultMode: 0440) and sets REPO_MANAGER_FORGEJO_TOKEN_FILE=/var/run/secrets/repo-manager/FORGEJO_READ_TOKEN (activity-core docs/rollout-owner-return-and-freshness-worker.md §3b, lines marked "only once 3c is resolved")
Rotation	every 180 days or owner change; Forgejo PATs have no server-side expiry
Front door	ops-warden activity-core-repo-manager-forgejo-read, follow-up after approval

Open choice for the reviewer: either a dedicated ClusterSecretStore openbao-activity-core-repo-manager-forgejo (CCR-2026-0031 pattern, below) or granting the existing openbao-activity-core store role read on the new path. The dedicated store keeps this high-risk org-wide read separate from the worker's other secrets and is the default here.

Attended sequence (after approval)

1. Reviewers approve and confirm the binding with the CCR tooling (credential-change.py approve …, confirm-binding …).
2. Founder, in their own terminal: delegated metadata apply (policy + auth role), then mint the PAT through warden access forgejo-admin-api-token --exec, verify scope, private-repository read and denials, write the value to OpenBao from stdin and read it back for equality. A bootstrap script modelled on scripts/openbao-bootstrap-core-hub-source.sh and scripts/provision-core-hub-forgejo-source.py is still to be written; it is not part of this draft.
3. Commit the two manifests and let Argo sync; check presence only.
4. activity-core adds the token env and mount lines from its rollout package §3b, syncs, and runs the memo 3 apply trials.
5. Add the ops-warden catalog entry and move the CCR to verified/active with evidence.
