Tools of CaliberAPI Pistol Optic Fit
	Description		Read-only	Idempotent	Open world
`check_fit`Answer whether a specific red dot optic fits a specific pistol, from source-cited data. Returns fit "direct" (mounts on the slide cut, with the footprint), "adapter" (only through the adapter plate chain in via, with plate maker, model, mount and presented footprints, and plate sources), or "unknown" (no cited fit in the dataset, which is not evidence it does not fit). Returns "needs_clarification" with candidates when a name is ambiguous; call again with a candidate slug. Report the answer exactly as returned: never call an adapter fit a direct fit, and never turn "unknown" into "does not fit". Cite with the returned citation line and link html_url.
