  notes: 'No published deprecation policy and no RFC 8594 headers. Observed behaviour (third-party evidence, the
    provider''s own n8n changelog 0.12.0, 2026-09-19): /v1/entreprise/{siren}/liens-capitalistiques disappeared
    from the grid and answers 404 without a replacement route or notice; the changelog also records the price of
    /v1/recherche as $0.001 in an older samples README versus $0.002 in the live spec. Deprecation is silent removal.'
