Summary

Adopt the producer's selected stock Recoil 2026.07.04 identity from HighBar #15.

• Keep the consumer contract byte-identical to the producer and require 2026.07.04 in native catalogue readiness and stock trace normalization.
• Update current-profile trace fixtures and their engine-bound revision. Preserve and explicitly reproduce the old hash-algorithm golden while refusing its old profile at new admission.
• Record the selected update, exact archive/source/headless hashes and remaining native qualification in BARC-01.5f.

Merge follows producer source delivery. Wire revision and queue policies are unchanged; historical attempts are preserved. Installed old packets are not new-engine evidence.

Verification

• Official archive digest and extracted binary --version: verified.
• Matching current-engine HighBar plugin compiled and installed in the separate version directory; four native test targets and Lua observer/float-ABI checks passed in the producer work.
• Producer/consumer contract and retained vector byte identity: passed.
• Stock contract vectors: passed.
• Stock trace normalization: 11/11 checks passed, including old-profile refusal and historical golden reproduction.
• Broker.NativeProof.fsproj Release build: passed, zero warnings/errors.
• git diff --check: passed.

No game startup, Count1 or useful-play acceptance is claimed. Existing complete-record policy/source qualification is unchanged. This change does not reopen completed V2 acceptance.
