ubc_domains, ubc_patterns, ubc_catalog, ubc_pattern_detail. Read-only access — the planner never writes.

Resource preference order

The planner prefers resources in this order:

1. cross_subsidy (Cloudflare-style — durable)
2. public_good (GitHub Education-style — gated but durable)
3. cac_funded (most SaaS free tiers — fine for now, may decay)
4. community (availability tracks donations)
5. trial (time-limited — flagged, not relied on)
6. unknown (treated as cac_funded)

Within the same tier, has_guide: true wins.

Staleness

Resources with verified_at older than 90 days get a warn tag; 180 days becomes stale. The planner can be invoked with exclude_stale=true to skip stale entries entirely.
