Module sources 

Binding sources. A data model path can follow a host source (exp:issues?board=…): the host registers one resolver per scheme, the router emits a bind op, the resolver’s emits land at the path.

ParsedSource

Functions

parse_source

exp:issues?board=b1&limit=20 → {scheme: "exp", name: "issues", params: {board: "b1", limit: "20"}}; None when it does not parse (catalog/host.json sources.pattern).

source_with_params

VAPP-122: source with params appended as its query, for the bind action (sourceWithParams): keys sorted, key and value percent-encoded, a null value skipped, an object or array as JSON, after ? or &. A repeated key parses with the last value, so a param overrides the source’s own.
