Read and Validate a Project Layer Manifest

A manifest is the project's INTENT record - which layers it should carry - distinct from the gq registry (the template catalog) and rfp_tracking (provenance). It is a CSV with exactly two columns, source_layer and source_type, living at the project root as rfp_manifest.csv beside the .qgs (so it syncs with the project). Types are validated against rfp_manifest_types().

Usage

rfp_manifest_read(path)

Arguments

path

Character. Path to the manifest CSV.

Value

A tibble with columns source_layer and source_type. The source path is attached as attr(, "path").

Details

Validation is strict and fail-closed:

• exactly the columns source_layer,source_type

• at least one row

• no duplicate source_layer

• no source_type outside rfp_manifest_types()

• the AOI layer whse_basemapping.fwa_watershed_groups_poly present with a refreshable (non-frozen) type - every rfp_source() pass rewrites it unconditionally, so frozen or absent is unenforceable intent
