  A2A Agent Card observed at the legacy /.well-known/agent.json path on a2a-browser.digiant.nz (the canonical
  /.well-known/agent-card.json answers a 404 nginx page). Grade is measured against the A2A 1.0.0 AgentCard object:
  'conformant' passes every structural check, 'near-conformant' is correctly shaped but omits optional fields,
  'flavored' fails a hard check and is an agent card in spirit rather than in schema. Provider-published by
  construction — served from the provider's own host; nothing here is derived or generated.

  deviations:
  - no-protocolVersion (the card carries a non-standard `protocol: a2a/0.3` string instead)
  - no-preferredTransport
  - non-standard top-level keys (schema, tagline, github, status, identity, tiers, infrastructure, operator)
  - skills[].id uses a slash namespace (browser/search, browser/fetch)
  - provider.organization present but no documentationUrl; the github link in the card (https://github.com/digiantnz/a2a-browser) answered 404 on 2026-09-19

    GET / answers 405 {"detail":"Method Not Allowed"} with `allow: POST`; POST / with a JSON-RPC 2.0 body answers 200 with a
    JSON-RPC envelope — an unknown method (tasks/get, tools/list) returns error -32601 "Method not found". robots.txt allows
    /.well-known/agent.json, /quote and /health and disallows /search and /fetch, so the skill endpoints were not exercised.
