manifest_file.rs

1//! Generic manifest -> concrete-provider dispatch, factored out of Soma's
2//! drop-in provider directory loader
3//! (`FileProviderSource::provider_for_catalog`, now in
4//! `crates/soma/application/src/providers/filesystem.rs`). Given an
5//! already-parsed, already-validated `ProviderManifest` and the file it came
6//! from, builds the matching adapter for its declared `ProviderKind`.
7//!
8//! The directory scan, fingerprinting, and Soma-specific manifest policy
9//! (reserved CLI command names, `SOMA_`/`LAB_` env-prefix denial) stay in
10//! `crates/soma/application` — see the PR10 deviation notes for why that
11//! orchestration did not move here.

17/// Builds the concrete adapter for `catalog`'s declared kind.
18///
19/// `env_prefix` is the product's env-namespace (e.g. `"SOMA"`), forwarded to
20/// the ai-sdk and python adapters' `EnvRequirement` resolution.
21///
22/// Returns `None` when the crate was not built with the feature that owns
23/// `catalog`'s kind. Every `ProviderKind` has a matching adapter here,
24/// feature-gated per plan section 3.9 ("Do not over-split") so a consumer
25/// only pays for the runtimes it actually drop-in-loads.
