Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

`get_data_freshness`	Returns when the data was last activated, how many segments are live, and the state of the last run. Call this first when you need to know whether the data is fresh.
`get_supplier_exposure`	The join: a federal contract whose supplier has an FDA shortage or recall. Every row carries company_name, confidence (exact, probable or weak) and match_method. A cross source join is NEVER exact, because FDA and USAspending share no identifier. The claim is: this government supplier has an active FDA shortage or recall. It does NOT claim that this contract delivers that drug. Without a key you get exact and probable matches only, at most 20 rows, without the evidence field.
`list_drug_recalls`	FDA drug recalls and enforcement reports. Filters: classification (Class I, II, III), company_id, limit.
`list_drug_shortages`	Current and resolved US drug shortages as reported by the FDA. Each row carries the generic name, the reporting company and its company_id. Filters: status, generic_name, company_id, limit.
`list_federal_drug_contracts`	US federal contracts for drugs, product service code 6505, from USAspending. Filters: agency, company_id, limit.

Schemas: list_tools.
