Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The static-host integration and Link repositioning changes are largely validated, but the current tests may miss unprefixed symbols in the complete static archive and stale velocity after Link resumes simulation.

oot_engine_step: retain the existing frozen clean-pose assertion, unfreeze Link
first, then perform a follow-up simulation step and assert the expected position
and near-zero velocity values. Ensure the post-unfreeze checks exercise normal
simulation and catch stale player->speedXZ or player->pushedSpeed state.

Check the complete static archive
The test references only oot_engine_api_version() from src/liboot_engine.c. The fallback definitions are in separate archive members from src/shim/fake_play.c and src/shim/stubs.c. Force complete archive inclusion, or inspect liboot.a for unprefixed definitions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Verify the reset after unfreezing Link.
Because the only post-pose step runs while Link is still frozen, the test does not verify behavior after normal simulation resumes. Keep this assertion, then unfreeze Link and add a follow-up step that checks the expected position and velocity. Otherwise stale player->speedXZ or player->pushedSpeed can pass this regression test.

What changed
Why
Static game hosts such as SM64 ports may export the same libultra compatibility names. Host-owned warps also need a clean pose handoff without old velocity leaking into the destination.
