Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
rescue_payloadRepair a malformed JSON or API payload so it matches a required schema. Use when a request, webhook, or tool output was rejected for schema validation errors: wrong types, a null where an array or object belongs, a forbidden extra property, or mismatched keys between two APIs. Deterministic repairs only. No semantic guessing. Refuses instead of inventing a value, and returns an exact change manifest plus a signed receipt so a silent 'fix' can never pass downstream unrecorded. Give it the payload that was rejected and the JSON Schema it failed. It returns one of: VALID the payload already conformed; nothing changed REPAIRED safely repaired; the returned payload satisfies the schema CANNOT_REPAIR no safe repair exists; repaired_payload is null on purpose INVALID_SCHE
