## Tools (as reported by the server, not verified)

- `directory.get`: The directory envelope \(v0.2, authority: manifest\). Real entries only — a data source enters on one of three admission routes \(E21\); an empty list is the honest state, never padded.
- `facts.badge`: shields.io endpoint JSON for one subject, derived from the fact table — «no facts» in grey when nothing is recorded, never rounded up.
- `facts.latest`: Latest effective facts per subject+metric from the versioned fact table — the bitemporal as\_of cutoff is exposed; an absent store is the honest empty view.
- `fedlex.check\_in\_force`: Check whether an act was in force on a date; false is a valid answer, never an error: use for «gilt das noch?» questions. norm.

- `meta.capabilities`: The platform capability register with published per-client coverage — tool names on this server ARE the capability ids.
- `meta.schemas`: Stage two of two-stage discovery: the full input schemas of the named tools, byte-identical to what tools/list carries, because both are read from the same router. An unknown id is refused by name rather than silently dropped.
- `meta.tools`: Stage one of two-stage discovery: every mounted tool with its capability id, domain, one-line summary and budget weight — and NO input schemas. Ask this first to learn what exists, then pull the schemas of the few tools you intend to call \(meta.schemas\). Context economy as a capability, not a client

- `standard.artifacts`: The manifest standard's sealed artifact register: path, canonical IRI, draft/published status and SHA-256 per contract file.
