Crate planarian_changes 

The change catalog (SPEC §9). Every ApplyChange names an entry here. An entry validates its arguments against permitted values and produces flat option assignments for planarian/overrides.nix. It never produces raw Nix. Risk is not read from here: the executor derives it from the evaluated generation (I14). affected_modules is only a hint.

The permitted values and the option each entry writes are owner configuration (services.planarian.catalog in the module), exported as JSON and loaded into CatalogConfig.

base with change’s assignments applied on top.

nix_path 🔒

Option paths are dotted identifiers; quote any segment that isn’t a plain one.

nix_string 🔒

nix_value 🔒

one_of 🔒

parse

Parse a file produced by render back into assignments. Only the exact rendered form is accepted; anything else is None.

permitted 🔒

render

target_of

The unit a per-unit catalog change is for (its service argument).

writeback

The ApplyChange that persists a runtime option (§12a write-back).
