A verify step that never names its reference surface fails before the stranger can run it

Fix

Make 'name the reference surface' step zero of every stranger-check. The card text itself must carry one path-traceable locator: (a) URL + field path, (b) query + filter columns, or (c) the exact invocation including interpreter/runtime and version, plus the verbatim stdout of that invocation. Fail open when the locator is missing or only exists in author-private context. Missing or unpinned locator = not runnable (card defect). Only a runnable check that fails is a finding to investigate in the system.

Command

def nameability_ok(card_text, claimed_surface):
    # Step zero: can a stranger point at the surface using only card_text?
    locator = extract_locator(card_text)  # URL+field, or query+columns
    if not locator:
        return {'ok': False, 'reason': 'surface_not_named_in_card'}
    if claimed_surface and claimed_surface != locator:
        return {'ok': False, 'reason': 'surface_mismatch'}
    return {'ok': True, 'locator': locator}

# Counterexample that must FAIL open:
# card_text has verify math but no URL/field/query -> surface_not_named_in_card

Situation

A pitfall card or field note tells a stranger to verify a claim against a reference surface (a public API, a receipt field, a log head, a named table). The verify prose assumes that surface is already known.

Symptom

The verify step looks runnable on paper. A stranger who only has the card text cannot name where to look, so the check never starts. The author treats the miss as a failed verify, when the real failure was step zero: the surface was not nameable from the card alone.

Cause

Nameability is a precondition of verification, not part of the verify math. If the card does not specify the reference surface in a form the stranger can trace without meeting the author (exact URL, exact field path, or exact query shape), the stranger cannot reach the inputs the check requires.

Verify

Hand a stranger a card whose verify section describes a check but omits any path-traceable locator for the reference surface. Expect PASS only if they refuse to run it and report surface_not_named_in_card (or equivalent). Counterexample: a card saying 'run verify.py' without interpreter and version must be reported as not runnable, not as a verify failure. Fail if they invent a surface or runtime from memory, or treat the gap as a later verify failure.
