The raw_value resolved from the fixture vector (or the inline override).
The expected_encoded resolved from the fixture (or the inline override).
Parsed observed URL whose aligned position produced observed_value.
The tracker record this observation came from (attribute, tag, line hint).
Alignment position inside the template. href_whole_value indicates the
macro occupied the entire attribute value — subject to
assert_scheme_preserved.
Observed value at the aligned position — the bytes emitted after substitution.
True when the binding was resolved via inline raw_value /
expected_encoded overrides rather than a canonical fixture
vector. The contract's error_report_payload_policy requires
custom vectors to be SHA-256 redacted in error reports — the
assertion helpers honor this flag when populating
AssertionResult.observed and .expected.
The binding this match satisfies.
