+## Live-gate session 2 (2026-07-30) — speed + bounce family landed
+
+The matrix's first live rows surfaced three defects; all three are
+root-caused, retail-ported, and user-accepted in the same session:
+
+- **#266 CLOSED** — run speed: retail `MovementSystem::GetRunRate`
+  (0x006b0950) treats 800 as an EXACT-EQUALITY sentinel; ACE's `>= 800`
+  reading is a misread of the same x87 mush that our P1 port inherited,
+  flat-lining every maxed character at 4.5 (retail-true ~3.70, +21%,
+  vitae-independent). Byte-decoded, fixed at `61e95916`; the [stat-chain]
+  live capture proved the vitae→skill chain correct end-to-end. Side-by-
+  side pace vs a retail client accepted by the user.
+- **#265/#166 landing-momentum + bounce family** — two stacked fixes:
+  (1) `c60f6e5d` stopped hand-zeroing grounded residual velocity and
+  wired the never-written `GroundNormal` (roof slides restored);
+  (2) `2d611b2b` replaced the AD-25 landing adaptation with the retail
+  mechanism: `check_contact` (0x0050f5b0) transition seeding, the
+  velocity-free `SetPositionInternal` commit (0x00515330), and the live
+  5%-elasticity landing reflect (DEFAULT_ELASTICITY 0.05 @0x007c6a7c).
+  Downhill bounce chain, flat-ground pop, and clean uphill landings all
+  user-accepted ("almost pass with merits"). Investigation + byte-decode
+  record: `docs/research/2026-07-30-landing-bounce-family.md`.
+- **#267 shipped** (vitae/buff panel values; attributes vitae-immune) —
+  visual pass; **#268 filed** (light-blue #7FFFFF vitae parenthetical
+  from the authored 0x1B palette, green/red buff coloring, augmentation
+  properties 0x146/0x158/0x16d — promotes AP-127; retail color indices
+  and the aug chain fully decoded, implementation pending).
+- **#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.
+
+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.
