# Installed SQL Object And Option Inventory

Generated by `scripts/generate-sql-object-inventory.sh` from
`sql/pgcontext--0.3.0.sql` and the HNSW reloptions callback. Run the generator
after changing the installed SQL contract, or use
`scripts/generate-sql-object-inventory.sh --check` to verify it. Do not edit
this file by hand.

The SQL contract registry owns lifecycle classification; this inventory pins the installed object and option shape consumed by the capability contract.

Full SQL artifact SHA-256: `e64dcfb289a4c21a05cc055a4a0e45f548258164674747660029a9b4d6ac1fdc`

The artifact fingerprint covers every object declaration, function result shape, cast method/context, operator identity, and opclass strategy. `contract_registry` separately compares installed functions and catalog objects bidirectionally, including typed operator and access-method/input-type opclass identities.
