Verify API filter serialization and result scope

Verification should prove that local filter intent survives serialization and that the result set matches the documented semantics. Run empty, single, multi-match, reserved-character, date, and repeated-key fixtures. Inspect actual identifiers and the final request, not only the filter label shown to a user.

Check whether the outcome improved

  1. Define filter expectations

    For every supported field, state operators, empty behavior, encoding, timezone, repeated-key rule, and expected result scope. Include an explicit unsupported case. Describe whether a no-match response is different from an omitted filter so a fallback cannot broaden results silently.

  2. Exercise the serializer

    Run the fixture set through the real encoder and compare final query, parsed request, status, and identifiers. Confirm reserved characters survive, dates use the intended boundary, repeated keys retain meaning, and empty values do not become an unfiltered request.

  3. Cover navigation and retry

    Apply filters through a page transition, refresh, and safe retry. Verify URL or request state remains consistent and results do not expand after an error. Check a nearby caller that shares the encoder, then retain the exact query and response evidence.

What to carry forward

Accept when each supported filter produces the expected request and identifiers, unsupported combinations fail visibly, and navigation preserves intent. Keep coverage open for undocumented parser behavior. Record fixtures, client revision, timezone assumptions, and any server-side limits.
