Intersignal Braid Light Client v1.5.2 - Warp-9.10 Physical UAT Fix Evidence
Generated: 2026-08-13

PHYSICAL UAT FINDINGS INCORPORATED
----------------------------------
PASS - native ad-hoc Braid.app/DMG built on Apple Silicon and launched from /Applications.
PASS - MacBook Pro and MacBook Air discovered each other bidirectionally on the private LAN.
PASS - explicit Air private-IP receiver bind reached LISTENING on 192.168.1.50:8745.
PASS - Pro -> Air TCP frame transfer reached the receiver and returned a structured rejection receipt.
FIND/FIX - UI/UAT generated receiver command used wildcard 0.0.0.0 with --allow-lan even though
           wildcard binds are intentionally governed by the stricter public-bind policy. Generated
           semantic LAN receive commands now bind to the detected private LAN IP.
FIND/FIX - a real all-minilm embedding contained a tiny negative component that underflowed to
           IEEE-754 FP16 negative zero (0x8000). The sender wrote that non-canonical encoding while
           the receiver correctly rejected it. Sender serialization now canonicalizes 0x8000 to
           0x0000 before payload digesting/signing; receiver rejection of non-canonical wire input
           remains unchanged.
FIND/FIX - DMG construction uses the Warp-9.9 private-mountpoint layout path and no /usr/bin/sync.
FIND/FIX - native verifier normalizes trailing TMPDIR slash before simulated install path creation.

REGRESSION RESULT
-----------------
PASS - 132/132 unittest cases across batched execution with ResourceWarning promoted to error.
       The first discovery batch completed the 122 non-Semantic-Capsule cases without a test
       failure before the host execution window expired; the 10 Semantic Capsule cases then
       passed in a separate invocation. No test case failed.
PASS - FP16 underflow regression explicitly verifies -1e-40 cannot serialize as 0x8000 and the
       resulting payload round-trips through the strict receiver decoder.
PASS - front-door environment regression requires the generated LAN receive command to bind the
       detected private IP and forbids --bind 0.0.0.0 in that command.
PASS - packaging regression requires the DMG helper to contain no /usr/bin/sync and the verifier
       to normalize TMPDIR.
PASS - 10/10 Semantic Capsule tests, including heterogeneous receiver-native re-embedding,
       exact-space fast path, no-capsule fail-closed, tamper, route binding, and post-commit finality.
PASS - 1/1 two-node optical QR smoke test.

RELEASE STATUS
--------------
NOT PUBLIC-READY. Rebuild the native Mac DMG from this exact manifest-verified source tree and
repeat the physical Air/Pro semantic UAT. Developer ID signing/notarization and the physical camera
rerun remain separate release gates.
