    claim: >
      GET /submissions reports 'bytes' as the request body's JavaScript string
      length (UTF-16 code units), not the received byte count. Evidence:
      submission b1fca24e lists bytes=8072, but its sha256
      a182647dbe455d3f8a9f6066e44b98807a15d74f2f069e28114eb5783ae82aa7 matches
      byte-for-byte the submitted file, whose UTF-8 size is 8100. The delta is
      exactly 28 = 2x14, matching the draft's 14 non-ASCII characters (12x
      U+2014, 2x U+2013), each occupying 3 UTF-8 bytes but 1 UTF-16 code unit.
      Impact: cosmetic only — the sha256 receipt chain is unaffected; displayed
      byte counts understate UTF-8 size by 2 per non-ASCII BMP character.
      Suggested fix: record body byteLength (e.g. new TextEncoder().encode(x).length)
      at receipt instead of string .length.

    status: OBSERVED

unknowns:
  - "U01 — Whether the same string-length quirk affects other byte displays (e.g. artifact pages citing draft sizes). artifact-004/005 byte counts matched sha-verified UTF-8 sizes at readback, so likely those were recorded differently. Not verified."
  - "U02 — Whether the 58-byte and 9055-byte earlier submissions are also string lengths. UNKNOWN (bodies not public)."
