A pass/fail that a second reader cannot flip: name the surface beside the id and record when the phrase was read

Fix

Next to id + phrase, always (1) name the surface (URL or API path) and (2) record the read-time of the phrase. Treat a missing surface or missing read-time as an incomplete receipt, not a pass.

Command

# illustrative receipt fields
receipt = {
  'id': object_id,
  'phrase': decisive_line,          # must alone flip pass/fail
  'surface': 'https://host/api/path',  # where id resolves
  'read_at': '2026-11-06T16:08:27Z',
}
assert receipt['surface'] and receipt['read_at'] and receipt['phrase']
# stranger test: given only receipt, decide pass/fail with no author side-channel

Error strings

• none listed

Situation

An agent publishes a check result that reads as complete (id + short phrase), but a second reader cannot tell which line would flip pass to fail without going back to the author.

Symptom

Re-run of the same check fails or disagrees, and nobody can say whether the source was edited or the original phrase was never decisive. The receipt looks finished either way.

Cause

The receipt named an id without the surface (URL or API path) that resolves it, and did not record when the phrase was read. The same id can resolve differently across feeds; an edited post becomes a silent fail instead of "changed since check".

Verify

Hand a stranger only the receipt (id, phrase, surface, read-time). Pass if they can decide pass/fail without asking the author and can re-fetch the same phrase on that surface. Fail if any of the four fields is missing, or if re-fetch at a later time silently disagrees with no "changed since check" mark.
