Fields

name: String

backend: String

connection: String

The DSN — the field that actually runs today. connection: → resolve_dsn → a real sqlx pool, with no global-pool fallback.

v2.67.0: still accepted (the live deployment depends on it), but it warns, and a store declared this way is INELIGIBLE for lease / observe / reconcile. You cannot govern what you did not declare.

resource_ref: String

v2.67.0 — the resource this store runs on. When present, the store DERIVES its DSN, its pool size and its sharing discipline from the resource. The derivation is the point; a bare reference would be the nominal link this cycle exists to avoid.

confidence_floor: Option<f64>

isolation: String

on_breach: String

capability: String

v1.30.0 (D11) — Pillar IV: the capability slug required to access this store. Empty = no capability gate. Validated at parse time against the closed slug grammar (shared with the v1.23.0 requires: grammar).

class: String

v2.48.0 — the secret-class prefix of a backend: secrets metadata store (doctrine rotation_without_revelation). A dotted lowercase identifier, e.g. crm — the store enumerates the tenant’s secrets whose keys live under <class>. (so class: crm covers crm.hubspot, crm.zoho.acct_x, …). REQUIRED when backend: secrets and FORBIDDEN otherwise (axon-T900): a class-less secrets store would enumerate the tenant’s ENTIRE secret namespace (llm.* included) — that over-broad view is unrepresentable, not discouraged.

column_schema: Option<StoreColumnSchema>

v1.31.0 (D1) — the OPTIONAL column-schema declaration. Three closed forms (inline / manifest-ref / env-var); None means the 37.x runtime+deploy path applies verbatim (D5 absolute). The v1.31.0 / v1.31.0 StoreColumnProof pass consumes this; the v1.31.0 CLI exports it. For a backend: secrets store this is always None in the AST (declaring one is axon-T900) — the fixed metadata schema is synthesized at IR time (store_schema::secrets_metadata_schema).

loc: Loc

leading_trivia: Vec<Trivia>

v1.5.2 — leading comment trivia attached to this declaration (comments preceding the declaration’s first token, since the previous declaration or file start). Empty by default.

trailing_trivia: Vec<Trivia>

v1.5.2 — trailing comment trivia (same line as the declaration’s last effective token). Empty by default.
