docs(#182): retire TS-3, narrow AD-25 + add AD-39/40/41, update ISSUES for the shipped rebuild

TS-3 (frames_stationary_fall accounting absent) retired — ported in the verbatim
UpdateObjectInternal rebuild. AD-25 narrowed to the remote-DR sweep (player half retired).
AD-39 (fsf ladder placement vs ACE's interleave), AD-40 (fsf bit-encode in the Core
writeback + CachedVelocity computed-not-consumed), AD-41 (candidateMoved gates only
handle_all_collisions) added. ISSUES #182 → rebuild shipped, awaiting the visual gate,
with the fsf-not-cached_velocity correction + the #137 Slice-3 residual note.

 ## #182 — Player wedges in a packed monster crowd, can't wiggle free (hand-rolled SphereCollision)
 
-**Status:** IN-PROGRESS — CSphere port shipped (`96ae2740`) but **visual-gate FAILED**;
-the real fix is a velocity-model rebuild (see design spec), deferred to a new session.
+**Status:** VELOCITY-MODEL REBUILD SHIPPED (Slices 1+2, `8bb8b204`→`54d56229`) —
+**awaiting the user visual gate** (crowd glide/land + normal-locomotion regression pass).
 **Severity:** MEDIUM
 **Filed:** 2026-07-07
 **Component:** physics / collision
 
-**GATE OUTCOME (2026-07-07):** The CSphere-family port below was faithful but did NOT
-fix the crowd feel and INTRODUCED an airborne "stuck in the falling animation"
-regression. Player-attributed retail cdb trace proved retail's local client fully runs
-player-vs-creature collision (~78% OK, glides) — NOT server-authoritative. Root
-divergence: retail's per-frame `UpdateObjectInternal` sets velocity = ACTUAL movement/dt
-(blocked → velocity collapses → gravity → glide); acdream integrates+reflects (jump
-velocity persists → hang). Fix = verbatim rebuild of the per-frame player-physics loop,
-velocity model first. Design:
-`docs/superpowers/specs/2026-07-07-player-physics-update-verbatim-rebuild-design.md`.
-#182 stays as the base (user), so the codebase carries the airborne regression until
-the rebuild lands.
+**REBUILD SHIPPED (2026-07-07):** The `CPhysicsObj::UpdateObjectInternal` velocity chain
+was ported verbatim, fixing the airborne "stuck in the falling animation" regression the
+CSphere port had exposed. **Refinement of the design's framing:** the airborne-stuck
+bleed is the `frames_stationary_fall` counter (`ValidateTransition` increments it when a
+gravity mover can't advance; `handle_all_collisions` zeros the velocity at fsf>1 → gravity
+resumes → glide/fall), NOT the `cached_velocity` field (a separate retail reporting/DR
+value). Slice 1 = the fsf round-trip in the kept transition internals (retires **TS-3**) +
+ungated small-velocity-zero; Slice 2 = `PhysicsObjUpdate.HandleAllCollisions` wired into
+`PlayerMovementController`, gated on `candidateMoved` (retail pc:283657), replacing the
+ad-hoc airborne-only reflect + Velocity.Z snap (AD-25 narrowed to the remote-DR sweep;
+AD-39/40/41 added). Tests: `FramesStationaryFallTests`, `HandleAllCollisionsTests`,
+`Issue182CrowdJumpTests` (a blocked jump bleeds to ~0 and grounds instead of hanging with
++12). Core 2617 / App 741 green. Plan:
+`docs/superpowers/plans/2026-07-07-player-physics-update-verbatim-rebuild.md`.
+**A/B instrument:** `ACDREAM_CAPTURE_RESOLVE` → `tools/analyze_resolve_capture.py` (before =
+52.8% OK / 22.1% stuck / 107 airborne-stuck; retail target ~78% OK / 0 airborne-stuck).
+**Residual (design §7 Q3, measure after the gate):** the general ground-jam (22% stuck vs
+retail 13%) may need a second divergence in the #137 sliding-normal-provenance family
+(TS-4) — the fsf ladder only climbs when the sweep runs, and a purely-horizontal push has
+its offset absorbed by the sliding normal. #182 keeps the CSphere port as the base.
 
 **Description:** In a large group of monsters packed around the player it was too
 easy to get stuck — the player couldn't shuffle/slide out. Retail leaves room to
