The 2026-07-31 #268 stat-chain package is implemented and user-accepted:
panel and Runtime movement share retail's complete augmentation ordering,
the authored per-fragment vitae/buff/debuff colors are live, and AP-127 plus
TS-8 are retired by focused and end-to-end packet tests. The remaining
implementation target is #269's capture-driven slope-slide feel residual,
followed by the unfinished live matrix rows.
TS-8 are retired by focused and end-to-end packet tests. #269's
capture-driven slope-slide residual is also closed and user-accepted:
`CTransition::validate_transition` now performs retail's non-OK-only
remembered-plane restore with the preceding `OBJECTINFO::kill_velocity`.
Campaign P now continues with the unfinished live matrix rows.

- **#269 filed** — slope-stop slide sometimes runs long. `calc_friction`
(0x0050ee70) and the complete jump chain (`GetJumpHeight` 0x006b09b0,
`InqJumpVelocity` vz=sqrt(h·19.6), 1.0 s/0.8 s powerbar charge) are
byte-verified identical — the user's jump-height hypothesis is
refuted; next step is the live cdb A/B decay-curve trace.
- **#269 closed 2026-07-31** — the live 2,184-quantum trace proved the
landing reflect and friction math were correct. ACDream omitted retail's
`OBJECTINFO::kill_velocity` before restoring a remembered contact plane
in `CTransition::validate_transition @ 0x0050AA70`, retaining full
downhill velocity while repeatedly re-grounding the mover. The exact
non-OK-only restore/kill order and final last-known validity overwrite
are now ported, focused/full gates pass, and the user accepted repeated
slope jumps. Evidence:
`docs/research/2026-07-31-269-slope-stop-capture.md`.
Matrix rows accepted so far: speed parity, roof slide, downhill bounce,
flat pop, uphill landing (rows 3/4/5-partial/12-partial). Remaining
rows: 1, 2, 6, 7, 8, 9, 10, 11 plus #269's slide feel. Suite at this
checkpoint: 10,031 passed / 5 skips / 0 failures.
