TL;DR: Capture multiplayer commands issued by the local player as well as commands received from peers. Make diagnostics check player ownership and explicitly flag immediate commands, roster changes and resync phases that the current replay path cannot yet reproduce.

Release 0.13.0 closes the local-send observation gap: native local commands enter the ring directly and never traverse the existing receive-copy hook. Three opt-in native observers retain the original instructions while recording local timed payloads and detecting local/remote immediate execution. Diagnostic failures do not change commands, registers, RNG or pause state.

Trace format 4 includes the native eight-slot roster and transport mapping. The comparator checks each command's logical actor against that peer's roster, supports transport-handle renumbering between peers, and rejects missing/ambiguous identity, different AI rosters, captures beginning in resync and coverage-gap events. Roster/sync transitions are observed between periodic checkpoints too. Older paired formats remain supported with their original evidence limits.

Includes prior stages. Review this stage against PR #15: Krarilotus/ucp_recorder@fix/live-replay-validation...feat/multiplayer-boundary-evidence.

Validation: 112 automated tests pass, including local-queue payloads, ownership, roster differences, immediate dispatch, hook conflicts, resync transitions and logging-failure pass-through. Original hook bytes pass for Crusader and Extreme; the ZIP builds successfully. Version/changelog and diagnostic instructions are updated. The publish-release workflow will be triggered explicitly for this PR.

This is diagnostic coverage, not multiplayer recording/playback. No live multiplayer test was performed. Immediate payload replay, DirectPlay system-event logging, synchronized starting snapshots, offline roster restoration, host migration, resync reconstruction and extension private state remain outstanding. The conservative gap policy can reject harmless immediate commands too; it does not silently assume a whitelist. Full RNG/resource agreement is not a full-world equality proof.

Native ownership and network-flow analysis is contributed separately in sourcehold/OpenSHC#220. Single-player simulation profile remains recorder-sp-v6, including PR #15's still-pending final live music-fix validation.
