# /map-check The read-only conformance front door for **Map Your Knowledge (MYK)**. It validates a scope against the named MYK sources and never invents rules of its own. > **Protocol provenance.** MYK v2.4 comes from [`map-rules/SKILL.md`](../map-rules/SKILL.md) and its routed references. Each finding carries its owning file and heading. ## The two iron rules 1. **Read-only forever.** map-check never writes, renames, or proposes-and-applies. Findings go to the Handler, and repairs run through `map-this` (one-off) or `map-maintain` (the tending loop). 2. **Unqualified CLEAN is banned.** The only positive verdict is: *"clean for checks {list} over inventory {source}, mode {mode}; not checked: {list}."* A crash can never read as a pass: the JSON envelope separates operational errors from findings by shape. ## Required checker companion The bundled deterministic companion [`references/tools/map-check.mjs`](references/tools/map-check.mjs) does the mechanical work with Node.js and no model in the validation path: ```bash node <this-skill>/references/tools/map-check.mjs <target-path> [--json] ``` - **Target classes:** an explicit path inside a scope, or a scope root (a directory containing `.myk/README.md` or a declared root map). Ambiguous or contested scopes fail closed (`scope-conflict`). - **Modes:** FULL when [`scope.md` — Organized-scope evidence](../map-rules/references/scope.md#organized-scope-evidence) resolves `.myk/README.md`; DEGRADED when the caller supplies an...
