docs(B.5): ship handoff + roadmap/CLAUDE update + file #63 #64

Phase B.5 (ground-item pickup, close-range path) shipped and
visual-verified 2026-05-14 at Holtburg. M1 demo target 4/4 ("pick up
an item") met.

New ship-handoff doc captures the 5-commit history including the
post-visual-test PickupEvent (0xF74A) wire-handler fix that closes
the local-despawn gap.

Roadmap and CLAUDE.md updated to reflect the ship + the new follow-up
issues:

  - #63 (MEDIUM) — server-initiated MoveToObject auto-walk not
    honored; blocks double-click pickup + out-of-range F. Filed as
    candidate Phase B.6. holtburger has the reference implementation.
  - #64 (LOW) — local-player pickup animation does not render
    (retail observers see it correctly). Likely a self-echo filter
    dropping UpdateMotion(Pickup) on the local player.

Carry-overs from B.4c (#61 link-cycle flash, #62 PARTSDIAG null-guard)
unchanged.

+## #64 — Local-player pickup animation does not render
+
+**Status:** OPEN
+**Severity:** LOW (visual feedback only — pickup completes correctly)
+**Filed:** 2026-05-14 (B.5 visual verification)
+**Component:** motion / animation routing for local player
+
+**Description:** When `+Acdream` picks up an item (B.5 close-range
+path), retail observers see the character play the pickup animation
+correctly, but the local view shows no pickup animation. The item
+despawns, the inventory updates, but the character's own
+bend-down-and-grab animation is missing.
+
+**Root cause / hypothesis:** ACE broadcasts `Motion(MotionCommand.Pickup)`
+via `Player_Inventory.AddPickupChainToMoveToChain` (line 711–713,
+`EnqueueBroadcastMotion(motion)`), which arrives as a normal
+`UpdateMotion (0xF74D)` packet. Retail observers route it through
+their remote-creature animation pipeline and render the pickup. For
+the local player, our `OnLiveMotionUpdated` likely filters self-echoes
+(local player drives its own motion via prediction, not server
+echoes) and drops the pickup motion. The pickup is a one-shot
+animation initiated by the server, so the prediction path has no
+trigger — and the echo path is filtered.
+
+**Acceptance:** When `+Acdream` picks up an item, the local view shows
+the same pickup animation retail observers see. Probably resolved by
+either (a) admitting server-initiated one-shot motions through the
+local-player motion filter, or (b) generating the pickup animation
+locally on send (mirroring retail's client behavior).
+
+**Files:** `src/AcDream.App/Rendering/GameWindow.cs` `OnLiveMotionUpdated`
+(motion routing); the self-echo filter is somewhere along this path.
+
+**Estimated scope:** Small-to-medium. Mostly investigation +
+1–2 commits.

+## #63 — Server-initiated auto-walk (MoveToObject) not honored
+
+**Status:** OPEN
+**Severity:** MEDIUM (blocks out-of-range Use + Pickup; close-range
+works fine)
+**Filed:** 2026-05-14 (B.5 visual verification)
+**Component:** motion / inbound MoveToObject handling
+
+**Description:** When the player triggers a Use or PutItemInContainer
+on a target outside ACE's `WithinUseRadius` (default 0.6 m), ACE
+runs server-side auto-walk via `CreateMoveToChain` →
+`PhysicsObj.MoveToObject` + `EnqueueBroadcastMotion(Motion(MoveToObject, target))`.
+Our client receives the `UpdateMotion(MoveToObject)` broadcast for
+the player but doesn't honor it: the character either visually
+drifts a bit toward the target and snaps back, or just stands still.
+ACE's MoveToChain then times out, the `success: false` path
+broadcasts `InventoryServerSaveFailed (ActionCancelled)`, and the
+pickup/use never completes.
+
+**User-visible symptom:** Double-click a ground item from any
+distance, or F-key it from > 0.6 m: character partially walks toward
+the item, then flips back to original position. No pickup.
+
+**Reference:** [holtburger simulation.rs:33–41 + 178–191](references/holtburger/crates/holtburger-core/src/client/simulation.rs)
+already implements client-side `MoveToObject` motion projection +
+auto-walk handling. That's the shape of the fix.
+
+**Root cause:** Our `OnLiveMotionUpdated` has no handler for the
+`MoveToObject` motion type; the broadcast is silently dropped.
+
+**Acceptance:** Double-click a ground item from 2–5 m away. Character
+auto-walks to within use radius, ACE's MoveToChain confirms success,
+pickup completes (including the existing PickupEvent despawn). Same
+behavior for Use on out-of-range NPCs.
+
+**Files:** `src/AcDream.App/Rendering/GameWindow.cs` `OnLiveMotionUpdated`
+(routing); likely a new `MoveToObjectMotion` handler in the motion /
+prediction layer + a server-acked position-update echo so ACE sees the
+player has reached the target.
+
+**Estimated scope:** Medium. Probably its own phase (B.6 or similar);
+not a one-commit fix. Compose from holtburger's pattern.
