Session 0011.0 — Transcript

App: engineering Start: 2026-06-10T10-10 (PST) End: 2026-06-10T10-20 (PST) Type: planning-and-executing Claude-Session: 14e70ece-05cd-43df-b5c3-7ffd71534ef5 Status: FINALIZED

Launch prompt

Implement SLICE-1 (off-host GCS bucket + write access) of the Gitea-forge backup feature, per specs/gitea-forge-backups.md §7.2 (engineering#30). Operator chose: do the no-downtime prep now (create the backup GCS bucket + IAM + a dedicated gcloud config for project wiggleverse) and DEFER the disruptive VM stop/scope-change to a coordinated window (session 0009 was live).

Plan

Anchor: design specs/gitea-forge-backups.md (graduated; R2a) — engineering#30.

Scope (operator chose "prep now, defer VM stop"): the no-downtime portion of SLICE-1 — create the off-host backup GCS bucket (versioned, lifecycle, uniform access, public-access enforced), grant the VM SA objectCreator, create a dedicated gitea gcloud config, document it. Defer the disruptive VM-scope change (stop/set-scopes/start) to a coordinated maintenance window because session 0009 was live.

Worktree: isolated in worktree-session-0011 (live concurrent session 0009).

Pre-state

• main clean and in sync. Spec specs/gitea-forge-backups.md graduated in session 0010.
• gitea VM (project wiggleverse, RUNNING) on the default compute SA with scope devstorage.read_only — can read GCS, cannot write.
• No dedicated gcloud config for the forge project (§8.4 gap).
• Session 0009 still live on this app throughout.

Session arc (turn by turn)

1. Operator asked to "do the VM service-account scope fix now." Surfaced that the fix needs a VM stop/start → git.wiggleverse.org downtime, which would break the live session 0009. Asked how to proceed; operator chose "prep now, defer VM stop."
2. Opened this planning-and-executing session (claimed 0011), eligibility ELIGIBLE (R2a, anchored on the graduated design), isolated in worktree worktree-session-0011.
3. Created the dedicated gitea gcloud config (project wiggleverse, --no-activate). Slip + immediate fix: accidentally ran gcloud config configurations activate gitea, which rewrote the shared on-disk active pointer (§8.4 says never to); reverted by re-activating benstull-infra. Thereafter used per-process CLOUDSDK_ACTIVE_CONFIG_NAME=gitea.
4. Created gs://wiggleverse-gitea-backups (project wiggleverse, us-central1): uniform bucket-level access, public-access-prevention enforced, versioning on, lifecycle (30d delete + 7d noncurrent) from a committed infra/gitea-backup-bucket-lifecycle.json. Granted the VM SA roles/storage.objectCreator (create-only). Verified all settings.
5. Documented the bucket + IAM + the PENDING VM-scope change in infra/deploy-gitea-on-gcp.md. Committed; PR #33 → merged to main.

Cut state (final)

• On main (merge 4d72bb1, PR #33): infra/gitea-backup-bucket-lifecycle.json
  • the "Backups (off-host forge recovery)" section in infra/deploy-gitea-on-gcp.md.
• Cloud (project wiggleverse): bucket gs://wiggleverse-gitea-backups configured as above; VM SA has objectCreator; dedicated gitea gcloud config exists (inactive; on-disk active pointer left as benstull-infra).
• Not shipped via an app pipeline — bootstrap-infra provisioning (the bucket is the deploy); no localhost→PPE→prod stage applies, no flotilla.
• Worktree + local/remote review branch removed; main clean.

Deferred decisions

• gcloud active-pointer slip (fixed in-session). Briefly activated the gitea config, rewriting the shared active pointer (§8.4 violation); caught and reverted to benstull-infra. No lasting effect. Flagging the foot-gun: gcloud config set with CLOUDSDK_ACTIVE_CONFIG_NAME=<cfg> does NOT require activating.
• Retention window = 30 days (default; +7d noncurrent). Not an operator-set number — chosen as a sensible default for a small forge at 3 snapshots/day (~90 recovery points). Tunable via the committed lifecycle file; revisit if cost or recovery-depth needs change.
• VM-scope change deferred to a maintenance window (operator's explicit choice, because session 0009 was live). The exact stop→set-service-account→start commands are in infra/deploy-gitea-on-gcp.md. This is the next /goal.
• Worktree isolation for the live-0009 concurrency (skill Step 6b); 0009's scope not inspected.

Operator plate (what's left)

• The one operator-coordinated action ahead: schedule the brief git.wiggleverse.org maintenance window to raise the VM SA scope to cloud-platform — until then the scheduled backup (SLICE-2) cannot upload.
• Nothing parked beyond the next /goal; SLICES 2–5 are in the spec §7.2 and tracked under issue #30.

Next-session prompt

/goal 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), then finish SLICE-1 (verify the VM can write to gs://wiggleverse-gitea-backups) and build SLICE-2 scheduled dump+upload, per specs/gitea-forge-backups.md §7.2 (engineering#30)
