Step 5.1: Client handshake handling - Implemented ClientEntity.HandleWelcomePacket: RTT ticks calculation using double + epsilon, enforces minimum 3 ticks, applies INPUT_BUFFER_HEADROOM, warps server state into StateBuffer at clientStartTick - 1, syncs lastServerConfirmedInputTick, and sets CurrentTick. - Added Phase5 EditMode tests: Handshake_CurrentTickCalculation_IsCorrect, Handshake_HandleWelcomePacket_SetsClientTickAndState, Handshake_LastConfirmedInputTick_Synced, Handshake_WarpedState_AllowsRingBufferWrite. Testing & Validation - All EditMode tests pass locally (Phase 5 tests green). Performance - No changes to hot paths; change limited to handshake path (non-hot). CHECKPOINT 5: Ready for CI validation on self-hosted runner.
Step 5.1: Client handshake implementation - Implemented ClientEntity.HandleWelcomePacket: RTTticks in double with tiny epsilon; enforces min 3 ticks; applies INPUT_BUFFER_HEADROOM; warps startState into StateBuffer at clientStartTick - 1; syncs lastServerConfirmedInputTick; sets CurrentTick; safe ring buffer writes. Step 5.2: Tests - Added Phase5 EditMode tests and Phase5 negative tests; local EditMode tests: 7/7 passing. Step 5.3: CI & Documentation - Restored Unity workflow for self-hosted runner and triggered CI; updated COMPLIANCE_LOG and ACTIVE_CONTEXT. Testing & Validation - Local EditMode tests: 7/7 passing; CI run in progress and pending green before merge. Performance - No changes to hot paths; handshake path is non-hot and zero-allocation where applicable. CHECKPOINT 5: Phase 5 implemented and locally verified; ready to merge after CI success and review.
