action disabled (PUC-10). TEL-3 (`catalog_exported`) is emitted once the stream

### Images (SLICE-7)
After a merchant confirms an import, the app transitions the run to
`fetching_images` and processes image URLs via a bounded thread pool
(4 workers). Each image goes through the SSRF guard, is decoded, and up to
four WebP renditions (`original`, `thumb`, `card`, `detail`) are written to
the objectstore under `product-images/`. Progress is tracked per run in
`image_progress` / `image_counts` / `image_outcomes` and visible in the
import history detail panel (PUC-8). TEL-4 (`image_phase_completed`) fires
when the phase finishes; startup recovery emits TEL-5 (`image_phase_recovered`)
when it resumes a stuck run.
#### `provision-bucket` — one-time gesture per environment (SLICE-7 PPE deploy)
Before the first SLICE-7 deploy, run the `provision-bucket` skill from the
engineering `launch-app` suite. This gesture:
1. Creates the GCS bucket `wiggleverse-ecomm-ppe-media` in the
`wiggleverse-ecomm` GCP project.
2. Grants the PPE VM's service account `roles/storage.objectAdmin` on the
bucket.
3. Sets an `import-drafts/` lifecycle rule (forward-compat for the draft-blob
migration deferred past SLICE-7).
After provisioning, `deployment.toml`'s `[overlay]` already carries:
```
ECOMM_OBJECTSTORE_KIND = "gcs"
ECOMM_OBJECTSTORE_BUCKET = "wiggleverse-ecomm-ppe-media"
```
so the next `flotilla deploy` picks them up automatically. GCS auth is the
VM service-account ADC — no credential bytes needed.
### RB-3 — image phase stuck
Triggered by ALR-3 (run in `fetching_images` > 2 h, or the same run recovered
≥ 3×).
1. **Identify the stuck run.** The import history (PUC-8, `GET
/api/products/imports/runs`) lists runs by status; look for a run with
`status="fetching_images"` that hasn't advanced.
```
journalctl -u ecomm.service | grep image_phase
```
2. **Restart to trigger recovery.** A process restart causes the startup
recovery scan to re-enqueue pending images for any run still in
`fetching_images` (TEL-5 confirms the resumption). Restarts are safe —
per-image claims are idempotent; already-fetched images are skipped.
```
systemctl restart ecomm.service
```
3. **If a specific image URL is the cause.** The `image_outcomes` field on
the run records per-image rejection reasons (SSRF block, resolution
rejection, network error, etc.). The merchant can update or remove the
offending URL and re-import.
4. **File a bug** on `wiggleverse/wiggleverse-ecomm` with the `run_id` and
the `image_outcomes` content from the log.
### ALR-3 — the log-based alert for stuck image phases
Run once per environment, at the SLICE-7 PPE deploy. Mirrors ALR-2's
approach — a log metric over the stuck/recovered signal, the existing email
channel, and an alert policy in project `wiggleverse-ecomm`.
```
# Select the deployment's gcloud config for this one process (handbook §8.4).
export CLOUDSDK_ACTIVE_CONFIG_NAME=wiggleverse-ecomm
# Log-based metric counting image-phase events (TEL-4/TEL-5 — stuck/recovered).
gcloud logging metrics create ecomm_image_phase_events \
--description="ecomm TEL-4/TEL-5 image phase completed/recovered (SD-0002 ALR-3)" \
--log-filter='resource.type="gce_instance" AND (jsonPayload.message:"image_phase_completed" OR jsonPayload.message:"image_phase_recovered" OR textPayload:"image_phase_completed" OR textPayload:"image_phase_recovered")'
```
Then attach an alert policy — **operator email channel, threshold any event >
0 within a 2-hour window, severity notify-only**. List channels first:
```
# Find the operator email channel's id for the policy.
gcloud beta monitoring channels list
```
Create the alert policy (Cloud Console or `gcloud alpha monitoring policies
create`); condition: `fetching_images` duration > 2 h **or** the same
`run_id` appears in TEL-5 ≥ 3 times.
