A full comparison against the 175-record ledger found stale guessed coordinates
in both relative slingshot chains. Circles 56/58/71/73 and lines 57/59/72/74
were displaced by up to 70 pixels. The corrected record-57 geometry then
exposed a second issue: readable C and Rust had collapsed two independent
binary response projections into one.
Transcribe the accumulated initializer coordinates exactly. Use the
swapped-component projection only to sign the current tangential response
`abs(normal_velocity) * response_tangent`, and use the standard dot product for
`spin_delta * 0.02 * response_tangent`. Correct the readable C evidence and
Rust together, extend live tracing with the six-byte spin field, and seal the
stopped-Wine transition from `(75530,354765)/(3000,15)` to
`(77369,356597)/(1839,1832)` with Real48 spin `-5.28` in both harnesses.
Test Plan:
- stopped Wine 11.15 record-57 injection/trace -- matched position, velocity, and spin
- `cargo test --workspace --all-targets --all-features` -- 123 passed
- `cargo clippy --workspace --all-targets --all-features -- -D warnings` -- passed
- `bash original/tools/test_reconstructed_c.sh` -- passed
- `python3 original/tools/audit_reconstruction.py --require-complete` -- passed with zero incomplete or unclassified units
- `python3 -m py_compile original/tools/trace_original_state.py original/tools/inject_original_state.py` -- passed
- `rumdl check --flavor commonmark RECONSTRUCTION.md CHANGELOG.md` -- passed
- `git diff --cached --check` -- passed
Repeated SIGSTOP-based injection can suspend Wine while its Win16 mutex is held
and eventually strand the timer callback. Make the short process-memory write
sequence the default between 30 ms callbacks, while retaining whole-process
stopping as an explicit single-probe diagnostic option.
Test Plan:
- `ruff check original/tools/trace_original_state.py original/tools/inject_original_state.py` -- passed
- live no-stop ball-state injection -- passed
- subsequent original timer updates remained observable
- `git diff --cached --check` -- passed
Expose the original detail-derived integration count, active-ball count,
gravity, maximum speed, and movement flags in live traces. Allow probes to
force one physics substep so a single collision response can be observed
without the default three-step timer batch obscuring intermediate state.
Record the dynamically verified type-2 rail response: resolve velocity in the
registered line's normal/tangent basis, apply the two original Real48
coefficients, then advance from the previous position using that response.
Test Plan:
- `ruff check original/tools/trace_original_state.py original/tools/inject_original_state.py` -- passed
- one-substep probes against both vertical shooter walls -- passed
- ordinary rail responses matched 0.6 normal rebound and 0.1 tangent coupling
- `git diff --cached --check` -- passed
Add an atomic live-state injector for the traceable Wine process. It updates
all recovered global and object copies of ball position and velocity while the
process is stopped, clears pending impulses, and re-enables normal collision
processing before resuming the unmodified executable.
This makes individual walls, circles, gates, and mechanisms reachable without
relying on random gameplay. Document the first controlled claw probe, including
its original terminal-18 animation, exact release state, and three-substep
gravity behavior.
Test Plan:
- `ruff check original/tools/trace_original_state.py original/tools/inject_original_state.py` -- passed
- controlled `(289,94)` injection and one-second live claw trace -- passed
- terminal-18 release matched `(325000,92000)` and `(0,1000)` -- passed
- `shellcheck original/tools/run_traceable_original.sh` -- passed
- `git diff --cached --check` -- passed
