Players reported targeting "feels inconsistent" because the server
PrototypeTargetRegistry anchors (alpha (-5,-5) r=8, beta (8,8) r=4) have
no visible meshes — the only console visible in the scene is the NEO-9
PrototypeTerminal at origin, which is unrelated to NEO-23/24 targeting.
Adds a display-only mirror of the server registry:
- client/scripts/prototype_target_markers.gd spawns a colored mast +
translucent flat radius ring per anchor so the lock radius is
visible in-world.
- client/scripts/prototype_target_constants.gd gains ANCHORS with
position/radius/color, matching PrototypeTargetRegistry.cs. Marked
display-only; server remains authoritative for validity.
- TargetLockLabel now renders a per-anchor distance line each physics
tick ("<id>: <d> m / <radius> (in|out)") so players can see the
relationship between the visible capsule and the lock radius and
immediately spot client/server position drift.
Also updates README, plan (Decision 4), manual QA (Section 1 boot +
Section 4 locomotion), and the review file's follow-up section to
describe the UX fix.
Review 2026-04-21 caught that the hybrid soft-lock refresh path is
unreachable during normal WASD locomotion. `main.gd` was wiring
`TargetSelectionClient` to `PositionAuthorityClient.authoritative_position_received`,
which only fires on boot sync and move-rejection resync — successful
`move-stream` 200s are intentionally silent to avoid RTT rubber-banding.
So walking out of an alpha/beta radius never triggered the throttled
`GET /target` the HUD depends on, and validity stayed stuck at `ok`.
Add a separate `authoritative_ack(world)` signal on `PositionAuthorityClient`
emitted from both `BOOT_GET` 200 and successful `move-stream` 200, and
switch `TargetSelectionClient` (+ `main.gd`) to it. The snap signal keeps
its current semantics so rubber-band suppression is untouched; the ack
signal is a pure heartbeat that cooldown-throttled consumers can hook.
Also adds an integration test that wires both real clients together (per
the review's suggestion 1) so renames or mis-wires between the two
scripts fail loudly rather than silently skipping the end-to-end path.
- `client/scripts/position_authority_client.gd`: new `authoritative_ack`
signal; extracted `_parse_world_from_response` helper to share JSON
parse across `BOOT_GET` and `STREAM_POST`; emit ack from both.
- `client/scripts/target_selection_client.gd`: rename
`on_authoritative_position_snap` to `on_authoritative_ack`; drop
`apply_as_snap` gate (no longer meaningful).
- `client/scripts/main.gd`: connect the new signal.
- `client/test/position_authority_client_test.gd`: assert ack on boot
200 and stream 200.
- `client/test/target_selection_client_test.gd`: rename tests for new
handler.
- `client/test/target_refresh_on_locomotion_test.gd`: new integration
suite wiring real authority + target clients.
- Plan Decision 3 + Tests row + Files-to-modify row updated.
- `docs/reviews/2026-04-21-NEO-24.md`: committed with blocking issue +
suggestions struck through with `Done.` notes per
planning-implementation-docs rule.
- `docs/decomposition/modules/documentation_and_implementation_alignment.md`:
E1.M3 row now reflects NEO-24 landed.
- `client/README.md` + `docs/manual-qa/NEO-24.md`: refreshed signal names
so the soft-lock refresh description matches the wiring.
Tests: 88/88 GdUnit headless passed locally.
