# Weekly SBOM Staleness Check

> **Emergency-paused 2026-08-20 (ACTIVITY-WP-0031).** The 2026-08-17 fire
> emitted 75 independent rescan tasks while the bounded replacement in
> ACTIVITY-WP-0030 is blocked on CUST-WP-0062. Keep this definition disabled in
> source and production. Its deterministic weekly summary is not sufficient
> reason to retain the unbounded `for_each` task fan-out.

When enabled, this runs every Monday at 09:00 Berlin time. It checks all
tracked repositories for SBOM staleness and flags any repository whose SBOM is
older than 30 days.

ACTIVITY-WP-0021: the fleet no longer treats Forgejo issues as the primary
landing zone for automated tasks. The deterministic **state-hub-progress**
instruction report below is the operator-visible evidence path. Task emission
via IssueSink remains optional and only fires when `ISSUE_SINK_TYPE` points at
a healthy sink (rest/state-hub); a broken Forgejo backend must not be required
for a green weekly completion.

```instruction
id: weekly-sbom-staleness-report
trusted_fields: []
model: deterministic
temperature: 0
max_tokens: 1
prompt: |
  Deterministic SBOM staleness report from context.repos (no LLM).
output_schema: ""
review_advisory: false
report_sinks:
  - type: state-hub-progress
    event_type: sbom_staleness
    author: activity-core
    topic_id: cee7bedf-2b48-46ef-8601-006474f2ad7a
```

Task emission uses the fleet default sink (`ISSUE_SINK_TYPE=state-hub` —
ACTIVITY-WP-0022): stale repos spawn `activity_task_spawn` progress events,
not Forgejo issues. The deterministic instruction always posts a
`sbom_staleness` summary for operators.

```rule
id: flag-stale-sbom
for_each: context.repos.repos
bind_as: repo
condition: 'context.repo.sbom_age_days > 30'
action:
  task_template: Run SBOM rescan for {context.repo.repo_slug}
  target_repo: context.repo.repo_slug
  priority: medium
  labels: ["sbom", "security", "automated"]
```

The bulk resolver exposes the per-repo entries under `context.repos.repos`.
The deterministic instruction posts `sbom_staleness` progress with stale repo
counts and a sample list for operator review.
