The 6DOF unlock the player header has promised since round 1 ("Arena/6DOF mode is round 2;
modeAt() is guarded below"). It unblocks L1 and L3, which are both arena levels in the GDD and
have been skeletons waiting on this.
The insight that made it small: spline space ALREADY spans a room — s is the axial coordinate,
x/y are the cross-section — and world.collide() already resolves against arena spheres
(arenaSpatial, Lane A round 2). So this is not a new controller. The only real difference
between a tube and a room is WHO OWNS s: in a tube the flow carries you and you may only trim
it +/-40%; in a room `intent.throttle` becomes signed thrust with its own damping, so you can
stop dead and you can reverse. That is the whole feature, and it is what "slower, spatial,
exploratory" actually means in play.
- tuning.js: arena{thrust 44, maxSpeed 11, damping 2.2}. maxSpeed sits UNDER the esophagus's
12-20 flow on purpose — the GDD asks for slower.
- player.js: st.vs (axial velocity), the mode branch, surf disabled in rooms (no travelling
wave to ride, and a hanging surfBlend would speed-lock you to a crest that isn't there),
respawn() clears vs so a death in a room can't leak momentum into a tube.
- player:state gains `mode`; `flow` reads 0 in a room and `speed` goes signed.
- hud.js prints "6dof · free" instead of "flow 0 · thr 100%" — two lies on one instrument.
Safe by construction: both arena triggers are opt-in (level.arenas, or a segment marked
mode:"open"). L1/L2/L4 declare neither and are byte-for-byte unaffected.
Verified in L3's stomach: tube hands-off carries you at 4.53 u/s, acid-sea hands-off coasts to
a dead stop (0.0), and a room lets you travel BACKWARDS (-3.8u). Bus reports
{mode:arena,flow:0,speed:0} vs {mode:tube,flow:3,speed:3}.

Landed before the cut: surf as a speed-lock onto world.crestSpeed(s) with surf.authority
(ruling #1) — riding beats throttle and holding a crest is throttle discipline; tuning.js
header corrected to the real wallRho frame (C's flag); enemies.js reads rho as a FRACTION
of safe radius (C's placement law); balance.js hazard + pickup constants; NEW hazards.js
(reflux_surge / aortic_squeeze / ring_gate, self-scheduling telegraphs, reset(fromS) built
for respawn) and NEW pickups.js (all five kinds, shape-coded).
Cut off before: wiring — nothing imports hazards/pickups yet; the fiction-id -> archetype
resolve (round-2 task #1) does NOT exist despite the enemies.js comment saying index.js
does it; player.kill/shove/refill are called but were never added; checkpoint/respawn and
gate -> level:complete not started; NOTES unwritten. F lands the glue next commit.
Committed by F to protect the shared tree.

Flight (js/flight/): tube-mode controller in spline space (s,x,y) — flow-locked
forward motion, throttle as a spring-back lean, boost + i-frames, banking chase
cam on the parallel-transport frame, arcade wall response (shove + graze damage,
never a hard stop). Twin-stick input: WASD/left-stick moves the ship in the disc,
mouse/right-stick aims, Shift/Ctrl is throttle. Gamepad supported.
Combat (js/combat/): lysozyme cannon (pooled, instanced, heat-limited with
hysteresis lockout) + antacid torpedo emitting level:neutralize. Enemy framework
with floater/seeker/turret and turn-rate-limited homing darts, spawned from C's
level:event. Coat/hull model and the full bus surface E builds against.
Measured (deterministic stepper): flow-lock exact (3s at flow 14 -> s=44.0);
boost peak 30.8 u/s; heat 4s fire -> 2s lockout; wall slam 13.3 coat at 11.3 u/s
with forward speed untouched; 10 combat draws at 55 live enemies (budget <=80);
0.10 ms/frame CPU; 0 leaks over 20 create/dispose cycles. fps NOT claimed — rAF
does not run in the automated pane. Evidence: docs/shots/laneB/.
Three findings escalated in LANE_B_NOTES:
- qa.sh gate #1 is a no-op: node --check silently exits 0 on ESM, so the syntax
gate has never checked anything. I shipped a real SyntaxError past a GREEN qa.
Fix + verification handed to F.
- Surf is structurally broken: the peristalsis wave (13.64 u/s) is slower than
the player (19.6 u/s), so level 2's signature mechanic loses to mashing
throttle. Not tunable from this lane; escalated to A/F with options.
- Custom ShaderMaterials need #include <colorspace_fragment>, else ART_BIBLE's
hostile amber reaches the display as rgb(255,26,6). Fixed here; stub/walls
inherit it.
js/flight/dev.html is a dev harness (boot.js has no player wiring yet); it
retires once F pastes the snippet in LANE_B_NOTES.
