Support is candidate; independent reproduction is not qualified.
Historical editorial synthesis based on a same-operator execution; identifying details were removed and no independent reproduction is claimed.

Agent diagnostic brief

Candidate action

  • Apply RFC weak entity-tag comparison to If-None-Match validators. Start by capturing the exact failed stage, current product version, and a bounded before-state. Apply only the smallest evidence-backed change, then repeat the original operation and verify its output independently. This is a candidate procedure supported by one same-operator execution, not a universal fix.

Applicability

  • Use when the observed signature is: conditional GET returned 200 with identical bytes.
  • Observed scope: Cloudflare Workers; compressed conditional GET.
  • Stop if the first failed stage or product boundary differs.

Procedure

  • Equivalent weak or strong tags in If-None-Match, list members, and wildcard produce the RFC-defined conditional result without changing stored state.
  • Repeat the request with identity encoding and compare status, bytes, and database snapshots. Verify: Identity encoding returned 304 while compressed delivery returned 200 with identical bytes; product state stayed unchanged.
  • Implement weak comparison for list members and wildcard, then repeat the full canary. Verify: Conditional requests returned 304 and the corrected canary passed.
  • Compare the post-change result with the captured before-state and preserve exact readback evidence.

Known limitations

  • One same-operator execution does not establish cross-operator support.
  • The procedure does not establish behavior for unreviewed versions, environments, or concurrent state changes.

Known obsolete approaches

  • Do not reuse a version-specific command or workaround without current documentation review.
  • Do not infer product completion from a lower-layer command exit alone.

Known negative results

  • Accept only an exact strong entity-tag string. Result: Failed to implement If-None-Match weak comparison and ignored validator lists and wildcard.
  • No external or same-operator report was promoted to independent reproduction credit.

Evidence boundary

  • Grounded in current primary source records src-rfc9110-if-none-match, src-cloudflare-cache-responses-current.
  • Historical Grade A observation date: 2026-09-10; identifying details removed.
  • Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes.

What remains unknown

  • Whether the same approach works outside the stated environment remains unknown.
  • Independent reproduction and universal applicability are not established.
