Rename mock variables to avoid shadowing GdUnitTestSuite.mock, drop
redundant await on synchronous assert_signal chains, and ignore
unused request_completed on HangingHttpTransport (API parity only).
Delete ground_pick and GroundPick wiring; PositionAuthorityClient now only
boot GET and move-stream POST. main.gd snaps on authoritative position only.
Update client/server READMEs, cursor rule example, NEO-22 plan note, and
GdUnit authority tests (stream 400 + boot resync).
Successful move-stream responses echoed server position roughly one RTT behind
integrated move_and_slide, so apply_as_snap still fired whenever dh exceeded
the locomotion skip threshold. Treat stream 200 as ack-only: do not emit
authoritative_position_received. Boot GET and click-move verify unchanged.
Update README + GdUnit expectation.
Introduce POST /game/players/{id}/move-stream with ordered targets, full-chain
validation before apply, and PositionStateResponse. Godot client uses camera-
relative WASD, queues samples, and snaps to stream responses; debug builds keep
click-to-move via ground_pick. Update READMEs, E1.M1 snapshot, and tests.
Migrate Jira NEON-* references to Linear NEO-* and linear.app links in
docs, Cursor rules, READMEs, and traceability comments. Renamed
implementation plans and dated reviews to NEO filenames.
Branch is based on origin/main with this commit only (no NEON-29
gameplay chain). client/README follows main’s district/map copy;
player.gd matches main aside from NEO-14 debug trace prefixes.
Raise stable-idle floor up-dot entry to 0.998 so Jolt normals on a flat
box can latch the idle anchor; 0.999 rarely tripped and corrective
move_and_slide + rim/bump nudges kept moving XZ.
Add STABLE_IDLE_ENTER_STREAK_FRAMES (2) before first latch; arrival
path still latches immediately. Unlatch budget 8→10 ticks.
(0.02, 0.995).normalized() dots ~0.9998 with UP, so default
STABLE_IDLE_FLOOR_MIN_UP_DOT (0.999) still treats it as flat.
Use the same tilted normal as min_flat_up_dot_parameter test.
feet_y wobble from move_and_slide on approach treads crossed
DESCEND_GOAL_Y_MARGIN each frame, toggling path vs direct steer.
Schmitt latch (WALK_VERT_ROUTE_LATCH_ON_SEP/OFF_SEP) with reset on
nav lifecycle. Extend debug_idle_trace with feet_y, vert_sep, vlat,
ncol. Add player_test for latch reset.
While _idle_stable_latched, use STABLE_IDLE_FLOOR_HOLD_MIN_UP_DOT (0.992) for
idle_support floor flatness so tread-edge normal flicker does not unlatch as
often. idle_support_is_stable gains optional min_flat_up_dot; unlatch streak 8.
Prototype position label updates in main _physics_process. Add GdUnit for param.
loose_ticks+ridged no longer forces ~0.8s corrective idle when floor normal
is still level (tread corner with vertical riser). Gate that branch on
shallow floor (dot < IDLE_RIM_MIN_FLOOR_UP_DOT). Bump unlatch streak to 5.
Update GdUnit + NEON-29 plan.
Hold latched zero-vel idle through STABLE_IDLE_UNLATCH_TICKS consecutive
unstable readings so thin tread lips do not drop into corrective move_and_slide
every other frame. Idle anchor now freezes Y as well as XZ. Reset latch on
goal/snap/arrival; seed latch on arrival when support is stable after idle tick.
Update hold_idle_anchor GdUnit expectation.
Stop forcing moving floor_max_angle for the full post-stop window on open
flat support; tighten ridged wallish threshold; relax stable floor dot;
on arrival, take stable-idle path when support is already stable after
one idle tick. Add GdUnit case for shallow seam normals.
idle_support_is_stable no longer treats every post-stop loose-tick frame as
unstable; only slide normals showing floor+wall (lip) keep corrective idle.
Deduplicate ridged-contact check via idle_slide_contacts_are_ridged.
Relax STABLE_IDLE_FLOOR_MIN_UP_DOT slightly for Jolt normal flicker.
Update GdUnit cases and NEON-29 plan note.
TerracePlatformB top is ~0.6 m above the floor; agent_max_climb only
limited nav links, while chained step assist could still climb in one
click. Refuse assist when goal surface is more than 0.35 m above feet
so the gold TerraceStepB path (or a second click) is required.
The vertical arrival error was computed with CAPSULE_HALF_HEIGHT (0.5),
placing code-feet at body_y - 0.5 = 0.4 on a floor-level player.
Step surfaces at Y=0.3 are only 0.1 m away from that reference, and
Jolt can nudge the body down to ~0.8 when the bottom hemisphere contacts
the step edge, making code-feet = 0.3 and vert_err = 0 — triggering
immediate arrival while the player is still at floor level.
Fix: pass CAPSULE_HALF_HEIGHT + PLAYER_CAPSULE_RADIUS (= 0.9) to
vertical_arrival_error so actual feet = body_y - 0.9 = 0.0 on the
floor. Step goals (Y=0.3) now give vert_err=0.3 >> VERT_ARRIVE_EPS,
preventing premature arrival. Arrival fires correctly once the step
assist lifts the player onto the surface (body_y=1.2, err=0).
Add two tests pinning the new pre/post-climb behaviour.
Apply the repo-local gdformat output to the touched GDScript files so the pre-push formatting hook passes. This is a formatting-only follow-up to the lint-hook cleanup.
Refactor the bump escape helper and shared test script loading so the branch passes the repo's pre-push GDScript lint checks. This keeps the runtime behavior intact while unblocking push and PR creation.
Harden idle settling so flat ground, obstacle contacts, and rare bump-edge cases stop drifting instead of looping corrective nudges. Also resolves the saved review follow-up items and syncs the runtime docs to the final feet-height and idle-anchor behavior.
ground_pick.gd now checks _collider_is_occluder before the walkable
break: when the ray hits a body in the "occluder" group it advances
OCCLUDER_PICK_THROUGH past the hit point and continues, unconditionally
and regardless of OcclusionPolicy fade state. Non-occluder click
targeting is unchanged.
Three unit tests added to ground_pick_test.gd covering occluder ancestry
detection. Plan open questions and module doc updated.
Review verdict updated to Approved; all blocking issues and suggestions
resolved and documented. Add auto-generated Godot .uid sidecar files for
occlusion_policy.gd and occlusion_policy_test.gd.
Adds OcclusionPolicy resource and wires it into IsometricFollowCamera.
Each _process frame, iterative rays from the camera eye to the player
focus detect bodies tagged "occluder"; their MeshInstance3D surfaces are
overridden with a transparent StandardMaterial3D (fade_alpha=0.25, instant).
Materials restore when the body clears the ray. Null-material surfaces
(e.g. the prototype Obstacle with no material assigned) receive a plain
transparent StandardMaterial3D so they fade correctly.
