Followup #5: after locking alpha, walking into beta's ring, stopping and
pressing Tab could still return `out_of_range` even when client and server
agreed on position (Δ=0). The freshness-kick move-stream POST and the
target/select POST race on separate HTTP connections so the select can be
validated against a stale stored snap.
Extend TargetSelectRequest v1 with an optional positionHint {x,y,z}.
Server uses the hint for the radius check and for the echoed
targetState.validity; the hint is advisory and does not write to the
position store (move-stream stays the sole write path). Client attaches
the hint automatically whenever set_freshness_kick(...) is wired, so
headless unit tests that skip the wiring fall through to the no-hint
behavior. Freshness kick is kept in place to refresh the stored snap for
later validity GETs but is no longer load-bearing for denial correctness.
Server: 3 new tests (hint accepts when stored is stale, hint-far denies,
hint never writes to position store). Client: 1 new test asserting the
hint is in the POST body when wired. All 62 server + 96 client tests
pass.
Plan Decision 8, review follow-up #5, manual QA section 6, and NEO-23
contract notes updated. New bruno request exercises the hint path.
All prototype targets now share `PrototypeTargetRegistry.SharedLockRadius`
(= 6 m). Anchors moved to alpha `(-3, 0.5, -3)` and beta `(3, 0, 3)` so
the two 6 m rings overlap ~3.5 m wide centered at origin, letting Tab
flip between targets without locomotion. Spawn `(-5, -5)` keeps alpha
in range (~2.83 m) and beta out (~11.31 m) so the existing soft-lock
denial QA path at spawn still holds.
`prototype_target_constants.gd` mirrors the shared radius + new anchors.
The range-aware Tab picker now **skips the currently-locked id** so Tab
always expresses a swap intent — if the only in-range target is already
locked, the fallback picks the next cycle id and the server denies
(preserves NEO-23's "Tab = visible denial when no swap possible" rule).
Tests:
- Server: new `PlayerTargetStateReaderTests.ComputeValidity_AtOrigin_…`
asserts both targets report `Ok` at origin. Existing boundary test
rewritten for the new alpha anchor.
- Client: new `test_tab_from_locked_alpha_at_origin_swaps_to_beta_when_both_in_range`
and `test_tab_when_only_current_lock_is_in_range_falls_back_to_cycle_for_denial`.
Existing in-range/out-of-range positions updated for the new layout.
Server 59/59 and client 95/95 suites pass.
Plan Decision 7, review follow-up #4, manual QA section 5 (new "Tab-flip
at origin" overlap sanity), and README updated. Per-target radii will
return with real combat design (E5.M1) — this is a prototype stub.
Previously Tab from no-lock always picked `ORDERED_IDS[0]` (alpha), so
standing next to beta and pressing Tab was denied with `out_of_range`
even though the client HUD clearly showed beta in range.
Added `PrototypeTargetConstants.next_in_range_id_after(current, world)`
which walks the cycle and returns the first anchor whose client-side
horizontal distance is within the anchor radius.
`TargetSelectionClient.request_tab_next()` prefers that pick when the
player reference is wired (same path `set_freshness_kick` uses) and
falls back to the plain cycle order when nothing is in range so the
server still owns the denial reason.
Server contract (NEO-23) untouched. Tests cover the beta pick, the
nothing-in-range fallback, and the no-player-ref regression. Plan
Decision 6 + review follow-up #3 + README + manual QA updated.
Fix "Tab says denied even though I'm in range of beta": root cause is the
race between the 20 Hz move-stream sampler and the target-select POST. A
Tab press right after the capsule stops can be validated against the
server's last sampled position, which trails the visible capsule by
several meters.
Client-side fixes (server contract unchanged):
- TargetSelectionClient.set_freshness_kick(authority, player): before each
POST /target/select, submit a move-stream with the current player
position so the server's stored snapshot is as fresh as possible when
the range check runs. Wired in main.gd; optional so tests without the
wiring still pass (regression-covered).
- PlayerPositionLabel now shows a "srv: (x,y,z) Δ=<d>m age=<ms>" line
populated from PositionAuthorityClient.authoritative_ack, so any
residual client/server divergence is visible in the HUD and future
reports can point at it directly.
- Two new tests: select POST kicks exactly one freshness stream with the
current player position before POSTing, and the kick is a no-op when
the wiring is absent.
Docs: plan Decision 5, review follow-up #2, manual QA section 5 and
section 1, and client README updated to describe the new behaviors.
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.
First instance of the new docs/manual-qa/ convention. Covers boot sync,
Tab happy path, out-of-range soft-lock (both by Tab and by locomotion
per Decision 2), swap-to-beta, Esc clear, denial UI hygiene, input
behavior, move-rejection coexistence, transport failure, and no-
regression checks against NEO-7/9/19/22.
