This file reserves session ID 0016 for engineering. The driver replaces this body with the full transcript and renames the file to its final SESSION-0016.0-TRANSCRIPT-2026-06-10T20-34--.md form at session end.

Launch prompt

Do the gitea VM service-account scope maintenance window (stop → set-service-account --scopes=cloud-platform → start, per infra/deploy-gitea-on-gcp.md Backups box) — unblocks gitea-forge-backups SLICE-1 (engineering#30).

Plan

Anchor: design specs/gitea-forge-backups.md (engineering#30, graduated; D-3 / §13 Q1: operator approved the maintenance window)

Execute the gitea VM service-account scope maintenance window — the SLICE-1 unblock (spec §7.2 SLICE-1, risk R-1). Procedure is canonical in infra/deploy-gitea-on-gcp.md "Backups" box:

1. Checkpoint-publish this transcript BEFORE the window (session-history lives on the VM being stopped).
2. Pre-checks via CLOUDSDK_ACTIVE_CONFIG_NAME=gitea (§8.4): VM RUNNING, record current SA (1061347810527-compute@developer.gserviceaccount.com)
   • scopes (devstorage.read_only).
3. gcloud compute instances stop gitea --zone=us-central1-a
4. gcloud compute instances set-service-account gitea --zone=us-central1-a --scopes=cloud-platform
5. gcloud compute instances start gitea --zone=us-central1-a
6. Verify: scopes = cloud-platform, same SA email, forge healthy (HTTPS git.wiggleverse.org + SSH :2222), on-VM ADC write-test to gs://wiggleverse-gitea-backups (proves the unblock; spec D-3).
7. Update the runbook's PENDING box (DOC-2) → branch → PR → merge.

Session runs isolated in worktree gitea-vm-scope-window (live concurrent SESSION-0009 in flight).

Execution record (checkpoint, ~20:50 PST)

The maintenance window ran and verified clean (spec §7.2 SLICE-1, D-3, §13 Q1):

• Pre-state (Compute API): VM RUNNING, SA 1061347810527-compute@developer.gserviceaccount.com, legacy default scopes incl. devstorage.read_only.
• Auth detour: the gitea gcloud config's CLI token had expired (interactive reauth required). ADC was still valid, so the read-only pre-check ran via the Compute REST API (project explicit in URL — §8.4 satisfied, no config pointer touched). Operator then ran gcloud auth login; the window itself used the documented CLI commands.
• Window: stop → set-service-account --scopes=cloud-platform → start (operator executed the start command directly). ~3 min downtime.
• Post-state: RUNNING, same SA, scopes = cloud-platform only.
• Forge health: HTTPS 200 on https://git.wiggleverse.org/ within ~20 s of start; SSH :2222 git ls-remote OK.
• Write test (the SLICE-1 proof): on-VM ADC upload to gs://wiggleverse-gitea-backups/maintenance/scope-fix-write-test.txt — gsutil cp 403s (its existence check needs objects.list, which create-only IAM denies — recorded in the runbook as a SLICE-2 note); pure JSON-API objects.insert returned HTTP 200. Test object verified then deleted from the laptop (operator creds; VM correctly cannot delete).
• DOC-2: runbook infra/deploy-gitea-on-gcp.md updated (PENDING box → build-state record; §1 + cert-rotation notes brought current) — PR #41, merged to main.

SLICE-1 is complete; SLICE-2 (scheduled dump + upload timer) is unblocked.

Deferred decisions

• Deleted the write-test object from the bucket with operator laptop credentials rather than leaving it for the 30-day lifecycle — judged trivially safe (artifact created seconds earlier by this session), but it is technically an irreversible delete.

Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Appended as the session runs; surfaced at finalize. Empty if none.
