# California CalAIM 1915(b) official source occurrences

`medicare_silver.ca_calaim_1915b_source_occurrence` · State programs · status live · 27 rows

Production-reconciled and exact-replay-idempotent lossless occurrence ledger for the CalAIM CA-0017.R10 authority chain. It preserves source-native role and authority status; distinct publisher, submission, approval, waiver-effective, implementation, table-as-of, and acquisition dates; official and acquisition URLs; exact content identity; alias ordinals; proposal and acquisition flags; raw manifest JSON; and Bronze lineage without inferring an operative program roster.

**Grain.** One row per frozen corpus snapshot and official DHCS source occurrence, including acquired aliases, proposed non-operative material, and exact source-limit occurrences.
