        endpoint; it does not exist. Filter client-side against this endpoint''s full response

        instead, exactly as the official SDKs do.'

x-forcedream-canonicalization:
  description: Non-standard OpenAPI extension documenting the exact, real canonicalization algorithm, since OpenAPI itself has no native way to express this. Cross-tested byte-for-byte and hash-for-hash across JavaScript, Python, and Go before any SDK trusted it -- not assumed.
  algorithm:
    step_1_build_signable: From an FdProof, construct an object with keys task_id, agent_id, input_hash, output_hash, cost_pence (Number-coerced), budget_pence (Number-coerced), started_at (Number-coerced), completed_at (String-coerced). If external_cost_hash is present (non-null), also add external_cost_hash (String-coerced) and retrieved_count (Number-coerced, defaulting to 0) -- 10 fields total instead of 8.
    step_2_canonicalize: Sort the signable object's keys alphabetically, then serialize as compact JSON with no whitespace after ':' or ','. Equivalent to JavaScript's JSON.stringify(obj, Object.keys(obj).sort()).
    step_3_digest: SHA-256 hash the canonical string, encoded as lowercase hex.
    step_4_verify: Base64-decode the proof's signature field. Hex-decode the digest to raw bytes. Verify the Ed25519 signature (raw bytes of the digest as the message) against the public key from GET /v1/workforce/proof/public-key.
  number_coercion_note: '"Number-coerced" must match JavaScript''s Number(x) -> JSON.stringify behavior exactly: whole-valued numbers serialize without a decimal point; fractional values keep full precision. A naive language-native int() cast (as first attempted in the Python SDK build) truncates fractional values and silently breaks verification. A naive %v-style generic formatter (as first attempted in the Go SDK build) can produce scientific notation for large values and silently breaks verification. Both were caught only by direct cross-language digest comparison, not by inspection.'
