fix(artifact): stop run checks filling D1 and prune old Resolutions - #688
Merged

Conversation
The skilld run sweep re-checked every runnable Skill about hourly. Each check wrote a Resolution with about 60 KB of attestations, and nothing deleted them. The 10 GB database filled on 2026-11-04 and every write since has failed. Check a ready Skill weekly and a failing one daily. Before each sweep, delete one batch of settled public Resolutions older than three days that no run check, grant, or newest Artifact attestation needs. The prune runs before the observed run records its start, so it frees space while the database is full. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

❓ Type of change
📚 Description
skilld-dbreached D1's 10 GB limit on 2026-11-04. Writes have failed since then: 22 scheduled tasks are stale and ingestion has stopped.The cause is the
sweep-skill-runstask. It re-checked each of about 140 runnable Skills roughly every 50 minutes. Each check wrote a new Resolution with its attestation (about 34 KB) and a second copy inartifact_attestations(about 24 KB). Nothing deleted these rows.artifact_resolutionsandartifact_attestationshold an estimated 6 GB, from sampled row sizes.This change does two things:
pruneSettledResolutionsdeletes up to 500 settled public Resolutions older than three days. It keeps any Resolution that a run check, a download grant, or the newest attestation of an Artifact still needs. Cascades remove the attestation, check results, and requester rows.The prune runs before the observed run inserts its start row. That way it can free space while the database is full. The CLI uses a Resolution ID only while it polls one run, so a three-day window is safe.
