Twilight Thorn: limited two-seat reaction proof

VUH-2569 remains open. This result qualifies the living reaction/actor-owner slice; it does not qualify a synchronized boss kill.

Build19 passed all202 serial CTest checks in153.01s. Its native inputs are based on edf2f2d; the landing integrates docs-only main e053a9e without changing those317 inputs or rebuilding. The DLL tested in live10 is the newly rebuilt trimmed binary. Earlier full-source live09 evidence does not qualify it.

Live10, 20261021-001728_net_twilight_thorn_reactions_1, passed34 steps in single-PC two-seat loopback. Both seats used the real-door route and existing pad pilots. Opening commands297/298/299 completed. Ground432 completed for owner0 and owner1; the latter joins the host offer, client queued receipt and host completion for resource67/occurrence31. Both pilots stopped at93.531s, both neutral releases succeeded, and four raw clips finalized in two paired 30-second blocks. The footage has recording gaps; log-confirmed completion and visible screen evidence are separate claims.

Independent result review verified all584 packet pins, the575-file exact source archive and safe closure. Four protected saves,14 game-root entries and527 assets were unchanged; no owned instances or relay listener remained.

One earlier queued432/resource28/occurrence14 has no host completion and its cause is unknown. The host was naturally downed once with no revive. There is no kill, reward, mission16, event315, onward-travel, captured426, Creeper-count, complete clone-visual or two-PC proof. Terminal support was deliberately excluded from this landing. Those requirements remain on VUH-2569.

Published on VUH-2569:

• Captioned paired-screen clip: 59.27s,30fps, host left/friend right, game-only views. Two requested30-second blocks at ordinary speed, recording gap omitted, no audio or hardware frame synchronization claim. Sampled raw and final frames were visually inspected. Host Key Counter and later ground Reversal are visible; not every logged completion is filmed. The issue embeds the playable clip.
• Decisive reports archive: unchanged live10/report.json, report.md, rc_proof.json, independent reviews/live10-result.md and checks/terminal.json, safety-closed.json, instances-closed.json. Small reports are bundled because the evidence store excludes individual non-media files below16KiB and Markdown.
• Exact source archive.
• Full build and202/202 checks.
• Evidence index: all published raw clips, native/runtime logs, read-only observations, contact sheets and composition checks.
