about

nx_cap_exists.nx -- LIB: the Nishi builder's "does this already exist?" anti-duplicate guard (importable). Operator: "make it not possible to build duplicates without a check ... a does this already exist capability." The builder (and Claude) call this BEFORE authoring an organ: `cap_index(ctx)` once builds an index of the whole organ tree (every `.nx` filename = the nx_<capability> surface, 12k+ organs, fast: getdents only, no body reads), then `cap_guard(query) -> 1 REFUSE (a matching capability EXISTS) | 0 ALLOW (novel)`. Filename-weighted, stopword- filtered so only DOMAIN words score. NEVER-BRICK (#26): read-only scan + in-memory index, zero writes to the tree. API: alloc the buffers, `cap_index(...)` -> NF, then `cap_query(q,...)/cap_guard(q,...)`. license_tier: ORIGINAL
