Living NPC Movement, Behaviour and Intelligence

Nishi vs the field — every Nishi cell is measured against real organ source at emit time; each gap names the watch contract that will close it.

How the beach girls move, decide and remember, measured 2026-08-27 from the served /world/beach page and the engine source against the August-2026 field: UE 5.8 motion matching, Behavior Trees, StateTree, Smart Objects and MassEntity; NVIDIA ACE on-device agents and the ProtoMotions physics-controller lineage; Convai; Virt-A-Mate with Embody, Voxta and vamX; Fable's Living Population; inZOI's Smart Zoi. Twenty rows are grounded on organ symbols, seventeen are named build contracts.

Layer 1 · Executive

Where we are. MEASURED 2026-08-27 from the served /world/beach page (455,592 B, 74 organ doors) and the engine source nx_wasm_craft. Twenty rows are grounded on funcs that exist: exact LBS (sk_skin), distance-driven clip phase (mob_spd_q8i, mobph), breath and blink (mob_breath_q8i), a declared pose contract (mob_pose), ground-following steps (mob_ground), A* in a library (pf_astar), needs (mobneed), the utility argmax (mob_tick), BT and FSM primitives (bt_tick), an agent brain (ag_tick), inherited personality (mobg), the thought ledger (th_mood), gossip (go_add), the bond (mobfr), event-sourced memory (cm_ctx), relationship recall (em_recall), the intent-respect meter (dl_rate_permil), neural motion tokens (mn_generate) and BVH ingest (m_info). The registered gate nx_wasm_craft_gate exercises the engine in-process, and its run of 2026-08-27 measured the schedule (12 girls asleep or fleeing at night, 12 awake by day), the ledger (hungry mood -18 naming hunger, -8 once fed, expiry), gossip confidence 85 falling to 70 across one hop, breathing at 211 mHz, and shy girls keeping 1367 units of distance where bold ones close to 577. Seventeen rows are build contracts. What the eye sees first is the gap: one walk clip, one held stand, a hand-tuned idle hysteresis, straight-line nudges, no routing, no avoidance, no foot lock, no motion matching, no physics; the pose contract has no page consumer; nx_pathfind and nx_char_ai exist and are not imported by the live world; nx_char_ai_gate and nx_footplant_gate are BUILT-UNPROMOTED; nx_sovworld_gate and nx_wasm_thirdperson_gate are PROMOTED-UNREGISTERED.

Where we need to go. OPERATOR ASK (2026-08-27): the beach models' movement, behaviour and AI intelligence are far below Fable, VirtaMate and other living-NPC systems -- add a /compare that measures it against the August-2026 field. Deliverable: girls who walk like the field (motion matching, foot lock, routing, avoidance, gaze), live like Fable's population (schedule, smart objects, a planner, reputation, reflection), talk through a sovereign door that respects the intent meter and passes a commitment test, and scale and get refereed -- every rung with a pre-declared done rule and a gate, with the engine's determinism, inspectable ledger and rumor mechanic kept as the exceed.

The unit. 1 u = one measured session-leg (organ plus gate plus live flip), the standing calibration. Local evidence: the synthroom room protocol SR1 (lib, gate 16 of 16, promote, register) was one leg on 2026-08-27; the gen trigger-first composer went from record-mining to deployed in one leg the same day. A rung that touches the wasm build closure is estimated at more because every mutant build of the world is a deploy.

Where we are: 20 of 37 rows. A living inner life on a prototype body. The exceed is real and narrow (a deterministic integer ledger, a decomposable mood, rumor decay); the movement deficit is total and visible.

Cost to walking right: 10 u. M0: motion matching, foot lock, pose clips consumed, routing, avoidance and gaze. Version 0.1 is a girl who walks around a house, stops on a planted foot and looks at what matters.

Cost to a living village: 8 u more. M1: schedule, smart-object reservation, a planner, reputation and reflection. 18 u cumulative = version 1.0, measured by the Fable bar -- beds for everyone and a day that runs whether you watch or not.

Cost to talking: 4.5 u more. M2: the dialogue door through the intent meter, ledger-driven expression, the commitment test. 22.5 u cumulative = version 2.0.

Cost to scale and proof: 9 u more. M3: LOD crowds, a physics tracking policy, the living-NPC referee bench. 31.5 u cumulative = version 3.0.

Research bar. UE 5.8 motion matching and its AI toolkit is measured on query-based pose selection over a database driven by a trajectory channel, with a rewind debugger, shipped in the engine [@ue5mm]; StateTree, Behavior Trees, Smart Objects and MassEntity beside it [@uestatetree] [@uebt] [@uesmartobj] [@uemass]; Godot's AnimationTree is the same shape for the open engine [@godotanimtree]. Theirs: the default toolkit every studio on the board can reach for. Ours: NP1 is this capability on our clip player; the field's own from-scratch recipe [@mmscratch] [@clavet] [@lmm] [@unitymm] is the spec.

Research bar. ProtoMotions and the physics-controller lineage is measured on a general tracking policy on about 142K motions that transfers to a real humanoid, generative policies such as MaskedMimic, Apache-2.0 [@protomotions]; the papers from DeepMimic to MaskAdapt [@deepmimic] [@amp] [@ase] [@calm] [@phc] [@maskedmimic] [@interprior] [@maskadapt]. Theirs: the research frontier of bodies that carry themselves. Ours: NP16 is the last rung on the ladder because the body must first walk right kinematically; the bar is kept honest by our no-float, deterministic constraint.

Research bar. Fable's Living Population is measured on over 1,000 hand-crafted NPCs with routines, jobs, beds, memory, plural local reputations and a life that moves along whether you watch or not [@fablexbox] [@fableiv] [@fablevgc] [@fablepop], due 23 February 2027 [@fablewiki]; the shipped ancestors are Red Dead Redemption 2's day-long schedules [@rdr2] and the Sims' commodities and utility curves [@sims4]. Theirs: the operator's named bar for a living village. Ours: M1 is measured against it: enough beds, a day that runs, reputations that differ by witness.

Research bar. inZOI Smart Zoi is measured on a shipped life sim whose NPCs plan, act and reflect on a 0.5B on-device Minitron model, show their inner thoughts and adjust tomorrow's schedule to today's experiences [@inzoi] [@nvace]; the 2026 stack behind it is the ACE Game Agent SDK with UE5 plugins [@acesdk] and Qwen3-8B on device [@aceqwen]. Theirs: the closest shipped relative of our thought ledger. Ours: NP11 and NP12 are its reflection and dialogue on our sovereign tier, refereed by the intent meter, the commitment test and memory-aware task suites [@scriptbench] [@genagents] [@minenpc].

Research bar. Convai and the dialogue stacks is measured on the hosted NPC service with Unity, Unreal and browser plugins [@convai]; Ubisoft's NEO NPC prototype on Inworld and Audio2Face [@neonpc]; Inworld itself now sells realtime inference rather than an NPC engine [@inworld]. Theirs: the browser comparator for a WebGL world. Ours: NP12 must reach a browser page the way Convai's PlayCanvas tutorial does, with every byte sovereign.

Research bar. Virt-A-Mate with Embody, Voxta and vamX is measured on the moddable sandbox whose companion plugins own idle life, possession and voice conversation [@embody] [@voxtavam] [@vamxchat]; Embody v1.6.3 is the one pinned bar for this domain. Theirs: the operator's named bar for a companion that feels alive up close. Ours: NP6 gaze and NP13 expression are measured against it.

Research bar. ORCA, steering and the planners is measured on reciprocal collision avoidance as a linear program per agent, thousands of agents in milliseconds [@orca], descended from Reynolds' flocking [@boids]; planning by GOAP and HTN [@goap] [@htn]; two-joint IK as two rotations [@twojointik]. Theirs: the crowd, planning and IK canon. Ours: NP5, NP9 and NP2 adopt the canon rather than a novelty.

Utility selection over needs and advertisements, with the night schedule (NL0)	mob_tick	LANDED; proven live 2026-08-27 by nx_wasm_craft_gate T44 (12 asleep or fleeing at night, 12 awake by day) and T45 (an advertisement row diverges a control-identical world)	Organ	0 u

Friendship bond that survives the save (NL3)	mobfr	LANDED; T46 grown 3 then 13 after a meet, load rc 0, survives load	Organ	0 u
Motion matching on the clip player (NP1)	np_motion_match	nx_nxa_play matches a query (root velocity, foot positions, the future trajectory over the organ's applied-step doors) against a feature database built from more than one clip and blends the selection with an inertializer; the gate proves that a target trajectory of turn, stop and back-pedal is matched from a database of at least three clips, that the selected pose never jumps more than the declared blend budget, and that a database of ONE clip reproduces today's walk exactly (the neg-control that the mechanism is reached); the foot-sliding permil measured by NP17's ruler must fall against the current page	Organ	3 u
Foot lock with two-joint IK (NP2) after NP1	sk_foot_lock	nx_skeleton locks the toe on contact through an inertializer and releases it when the animation drifts past a declared distance, with two-joint analytic IK on the leg; the gate plants a sliding clip and proves the locked toe's world displacement during contact is zero to the quantum and that the release fires at the declared distance; a mutation bite of the lock is killed	Organ	2 u
Pose clips consumed by the page (NP3)	gpe_pose_clips	clip selection is ENGINE-side, per the native-only delivery model: mob_pose names the active clip id inside the organ and the emitted page merely samples the clip the organ names through the door contract, with no selection logic in client-readable JS; the gate proves a world with a sleeping girl serves pose id 2 through the door, that the emitted page samples the named clip, and that mobpose is among the doors the page calls (today it is not, measured over the served page's 74 doors)	Organ	1 u
Routing in the live world (NP4)	mob_route	pf_astar composed into mob_tick over the voxel walk grid, with a per-NPC path cache and a re-plan on block edit; the gate proves a girl whose target lies behind a placed wall reaches it around the wall inside a declared tick budget while the control world with no wall walks straight, and that the T4 determinism checksum still holds	Organ	1.5 u
Reciprocal avoidance (NP5) after NP4	mob_avoid	an ORCA-class velocity choice between NPCs in integer arithmetic; the gate proves two girls on a collision course pass without overlap and that a single girl's path is unchanged (the neg-control), measured on the 12-girl ring	Organ	1.5 u
Gaze as a door (NP6)	mob_gaze	the organ chooses each girl's look-at target (the player inside conversation distance, the girl she is talking to, the smart object she walks to) and the page reads it; the gate proves a girl in SOCIALIZE looks at her partner and a girl in FORAGE at her target, never at the camera	Organ	1 u
Schedule as data (NP7) after NP4	mob_schedule	a per-NPC schedule row (home, work, pub, bed) read from conf, with beds counted per settlement and a refusal when a settlement has fewer beds than residents; the gate proves the Fable bar -- every girl in a bed at night, at work by day, and a village one bed short REFUSED by name	Organ	1.5 u
Smart-object reservation (NP8) after NP3,NP7	mob_reserve	an object advertises to needs and reserves one slot for one NPC, releasing on leave, and pose ids 4 and 5 land through it; the gate proves two girls cannot hold one slot and that a released slot is retaken	Organ	1.5 u
A planner (NP9) after NP7,NP8	ca_plan	GOAP or HTN over the needs and advertisements, emitting a sequence (walk to food, forage, rest) that the per-tick argmax cannot express; the gate proves a plan of at least three steps executes in order and that removing the goal yields no plan	Organ	2 u
Reputation carried by gossip (NP10)	go_reputation	gossip predicates grow from FRIEND and TAKEN to witnessed deeds, each NPC weighing them through her personality bits; the gate proves the same deed reads kind to one girl and shrewd to another, and that an unwitnessed deed spreads nothing (the neg-control)	Organ	1.5 u
Nightly reflection (NP11) after NP7	th_reflect	at REST the ledger is folded into a higher-level memory that adjusts the next day's schedule and advertisement weights; the gate proves a girl who was hungry every day for three days forages first on the fourth, with the fold journaled	Organ	1.5 u
The dialogue door (NP12) after NP10	cm_npc_turn	a turn takes the ledger, gossip, bond and persona as context through the sovereign tier or the egress warden and returns speech plus a structured intent; the gate proves the intent-respect meter refuses an escalation by rule and that no byte leaves without the warden's class	Organ	2 u
Ledger-driven expression (NP13)	morf_mood_drive	the MORF blendshapes read the mood and its strongest reason; the gate proves a negative ledger lowers the mouth corners and a positive one raises them, with the fragment-shader mouth line retired	Organ	1.5 u
Commitment test (NP14) after NP12	dl_commitment	an NCP-Bench-class test over declared commitments for any LLM-driven turn; the gate refuses a dialogue build whose survival over 20 turns falls below the declared bar, and a planted contradicting turn is caught	Gate	1 u
LOD crowds (NP15) after NP4,NP5	mob_lod	tick and draw tiers by distance so hundreds of girls live and at most the near ring animates fully; the gate proves 200 mobs tick inside the frame budget on the box and that a far girl's state advances identically to a near one's	Organ	2 u
A physics tracking policy (NP16) after NP1,NP2	mn_track_policy	a no-float tracking policy that carries the body under a push and recovers from a fall; the gate proves a pushed girl recovers within a declared window and that the unpushed control replays bit-identically	Organ	5 u
The living-NPC referee bench (NP17) after NP1	gb_npc_bench	a judged clip set (foot-sliding permil, interrupted-walk artifacts, idle believability) scored by an external judge panel and published with n and a Wilson interval; the gate refuses a locomotion rung whose score does not exceed the current page's with non-overlapping intervals	Gate	2 u

Layer 3 · Engineering

How this is scored. Every Nishi mark is measured: the generator reads the real organ source on disk and requires the implementing symbol to exist (no self-grading). A watching tag names the organ and symbol contracted to close a gap — the mark flips itself on the next compare beat when that workstream ships, and the comparewatch- plane row flips with it. The flip is necessary, not sufficient: it proves the symbol exists, never that the capability is good. The bar is the rung's pre-declared done-rule, proven by its gate — a symbol shipped without the behaviour behind it is a defect, and the flip is exactly what makes that defect visible instead of quiet. Competitor marks record documented capability presence — presence, not depth or scale. Adoption is measured too: every measured row carries where its organ stands on the estate's ladder (source → built → promoted → registered → invoked; libraries by importer reach minus validation importers; gates by the execution surfaces that run them). A row is fully adopted only at the top of its ladder; anything short is tagged partial with the exact remedy, so a build nobody promoted can no longer read as shipped. Census stamps: importers asof 1787849099, gate census asof 1787855507 (unix seconds; -1 = census absent).

LOCOMOTION
exact linear-blend skinning of the whole rigged mesh at the asset's real dimensions -- affine per-joint form, weights renormalised to sum exactly Measured: `sk_skin` exists in `runtime/nx_skeleton.nx`, verified at emit. UE and Godot skin natively and drive the skin from Pose Search or an AnimationTree [ue5mm] [godotanimtree]; ProtoMotions drives simulated SMPL-family bodies and the Unitree G1 [protomotions]; Convai animates engine characters through its Unity and Unreal plugins [convai]; Virt-A-Mate is a Unity title whose Person atoms are driven by plugins such as Voxta [voxtavam]. Fable and inZOI are 3 from silence: a shipped title necessarily skins its cast and the held pages describe none of the method [fablexbox] [inzoi]. Ours: the NXA pose player applies the spec's affine form over rigs of 104 to 370 joints and up to 423,919 vertices, no hierarchy walk at runtime Adoption: `LIB-WIRED importers=19 nonval=12` — fully adopted (top of its ladder).	●	◉	◉	●	◉	◐	◐
clip time driven by distance moved -- the page advances the gait clip from the organ's applied-step doors (mobdx, mobdz, mobdy) so nobody walks in place or moonwalks, heading gated on real speed Measured: `mob_spd_q8i` exists in `runtime/nx_wasm_craft.nx`, verified at emit. Motion matching selects the pose whose future trajectory matches the simulation object, which is the field's structural answer to foot sliding [ue5mm] [mmscratch] [clavet]; the tracking-policy line makes the physics carry the feet [deepmimic] [phc]; Convai and Virt-A-Mate inherit their engine's locomotion [convai] [embody]; Fable and inZOI 3 from silence. Ours: one walk clip, phase = distance times milliseconds-per-block derived from the clip's own root travel; no search and no second clip to blend Adoption: `LIB-WIRED importers=7 nonval=3` — fully adopted (top of its ladder).	●	◉	◉	●	●	◐	◐
stop at a foot-plant, not mid-swing -- the clip eases to the nearest double-support phase while the idle pose blends in, with hysteresis (enter idle at 0.03, leave above 0.15, release over about 400 ms) Measured: `mobph` exists in `runtime/nx_wasm_craft.nx`, verified at emit. Motion matching plus inertialization gives a planted stop by construction [mmscratch]; UE ships a rewind debugger to tune exactly these transitions [ue5mm]; the Unity motion-matching package exposes inertialize blending and foot locking as switches [unitymm]. Ours is a hand-tuned hysteresis on the page and its two thresholds are literals in the emitter, named as debt in npcai.plan Adoption: `LIB-WIRED importers=7 nonval=3` — fully adopted (top of its ladder).	●	◉	◉	●	●	◐	◐
idle life -- breathing on a spring anchor, gait bob carried by tissue not bone, a blink about every 4 s with a per-girl phase, irises that track the viewer Measured: `mob_breath_q8i` exists in `runtime/nx_wasm_craft.nx`, verified at emit. Virt-A-Mate leads: its companion plugins exist for exactly this -- Embody's Improved PoV, Passenger and Snug for possession [embody], Voxta's scene-aware reactions and Timeline triggers from a live conversation [voxtavam]. UE has the tools and no default idle-life system (1); ACE animates faces from audio with Audio2Face-3D [nvace] (1); Convai drives lip sync and animations through its plugins [convai] (1); Fable and inZOI 3 from silence [fablexbox] [inzoi].

the pose contract as data -- 0 idle-stand, 1 walk, 2 sleep-lying, 3 flee-run, 4 sit, 5 lie-awake, ids 4 and 5 reserved for the smart-object chain Measured: `mob_pose` exists in `runtime/nx_wasm_craft.nx`, verified at emit. UE StateTree tasks and Virt-A-Mate Timeline carry pose vocabularies as data [uestatetree] [voxtavam]; ACE's Kimodo generates a motion from a text prompt [acesdk] (1). Ours is DECLARED AND NOT CONSUMED: the served page reads 74 organ doors and mobpose is not among them, so a sleeping or fleeing girl still plays the walk clip or the held stand -- the watch row below names the fix Adoption: `LIB-WIRED importers=7 nonval=3` — fully adopted (top of its ladder).	●	◉	●	●	◉	◐	◐
terrain-following steps -- a ground query under the next step with auto step-up, and a voxel-march occlusion so a girl never pokes through a block face Measured: `mob_ground` exists in `runtime/nx_wasm_craft.nx`, verified at emit. UE's navmesh and character movement own this [uebt]; ProtoMotions trains terrain navigation in simulation [protomotions]; Convai and VaM inherit the engine [convai] [embody]; Fable and inZOI 3 from silence.

A* grid routing -- integer, Manhattan-admissible, optimal on a 4-connected grid, path reconstruction Measured: `pf_astar` exists in `runtime/_hdl_build/nx_pathfind.nx`, verified at emit. The field's default: F.E.A.R. plans paths with A* and actions with the same search [goap]; UE routes over a navmesh [uebt] and Mass crowds over ZoneGraph lanes [uemass]; ACE agents act inside the host engine's navigation [acesdk] (1). Ours EXISTS as a library the live world does not import: nx_wasm_craft steers by straight nudges plus a ground query, so a girl cannot walk around a house Adoption: `LIB-WIRED importers=9 nonval=2` — fully adopted (top of its ladder).	●	◉	●	●	●	◐	◐
BEHAVIOUR
needs -- hunger, energy and loneliness drift on a staggered per-handle clock so the village never moves in lockstep, seeded per NPC Measured: `mobneed` exists in `runtime/nx_wasm_craft.nx`, verified at emit. The Sims' commodities and utility curves are the canonical form of this [sims4]; inZOI's Smart Zoi acts on its current needs and adjusts its day to its experiences [inzoi] (2); Fable's routines imply needs without describing them -- sleep, work, the pub [fablexbox] (1); ACE reflects on needs through the Smart Zoi it powers [nvace] (1); UE, Convai and VaM ship no needs model (absent from the evidence held). Ours: four integer slots per NPC, hunger and loneliness grow, energy drains, on a clock offset by the handle Adoption: `LIB-WIRED importers=7 nonval=3` — fully adopted (top of its ladder).	●	○	●	○	○	●	◉
utility selection -- WANDER, SOCIALIZE, REST, FORAGE and FLEE picked by an argmax over needs times smart-object ADVERTISEMENT rows, repicked on a staggered 240-tick clock, night forcing REST, the mood bending the scores, wardens hunting with a radius that widens at night Measured: `mob_tick` exists in `runtime/nx_wasm_craft.nx`, verified at emit. The Sims weighs every course of action against a utility curve and randomises to avoid predictability [sims4]; UE ships Behavior Trees, StateTree and Smart Objects as the selectors [uebt] [uestatetree] [uesmartobj]; inZOI's Smart Zoi thinks about what to do next from personality, experiences, relationships and needs through an on-device SLM [inzoi] (2) and ACE is the stack it runs on [nvace] (2); Convai NPCs act on perception through its action abilities [convai] (1); Fable's NPCs follow routines whose selector is undisclosed [fableiv] (3); VaM has no autonomous selector (absent from the evidence held). Ours reads needs and P_ADV rows, both data, and the operator's stated law is that behaviour is picked by needs, never a dice roll Adoption: `LIB-WIRED importers=7 nonval=3` — fully adopted (top of its ladder).	●	◉	◉	●	○	◐	◉
behaviour tree and FSM primitives -- SEQ, SEL, COND and ACT over a blackboard bitmask; a transition-table FSM Measured: `bt_tick` exists in `runtime/_hdl_build/nx_char_ai.nx`, verified at emit. UE Behavior Trees run branches over a Blackboard that serves as the brain [uebt]; F.E.A.R. reduced its FSM to Goto and Animate and let a planner sequence them [goap]; VaM scenes are trigger graphs (1) [voxtavam]; ACE's Game Agent SDK sequences NPC actions and guards against infinite loops [acesdk] (1); Convai action API (1) [convai]. Ours is a library the live world does not import, and its gate nx_char_ai_gate is BUILT-UNPROMOTED (measured 2026-08-27) Adoption: `LIB-GATE-ONLY importers=2` — PARTIAL: imported only by validation organs (gates, tests, benches): wire it into a shipping program. adoption LIB-GATE-ONLY importers=2	●	◉	●	●	●	◐	◐

UE's Behavior Tree quick start is exactly patrol-or-chase [uebt]; ACE autonomous teammates and enemies -- PUBG Ally, MIR5's adapting bosses -- are the shipped form [nvace] [acesdk]; Convai characters perceive and act (1) [convai].

SOCIAL
personality as inherited genome bits -- a bold-to-shy spectrum sets approach, stop distance and retreat, habituation gated on loneliness, and an F-formation ring slot around the player so N approaching girls never bunch into a queue Measured: `mobg` exists in `runtime/nx_wasm_craft.nx`, verified at emit. Fable's cast is over 1,000 NPCs each with roles, personalities and routines [fableiv] (2); inZOI's Smart Zoi acts on personality traits, a considerate one offering directions or food [inzoi] (2); ACE and Convai carry persona as prompt data [acesdk] [convai] (1); UE and VaM have no personality model by default (absent from the evidence held).

INNER LIFE
the thought ledger -- eight TTL'd thoughts per NPC (rain, fear, met you, slept well, hungry, saw a taking, heard someone was taken, heard of your kindness, good company); the mood is the sum of live thoughts, always decomposable into its reasons, and the HUD prints the strongest live reason Measured: `th_mood` exists in `runtime/nx_wasm_craft.nx`, verified at emit. inZOI shows a Smart Zoi's inner thoughts in real time and the reasoning behind each action [inzoi] (2); Fable's NPC memory changes how a character feels about you, the beggar you enriched and the spouse you killed [fablexbox] (1); Generative Agents store a complete natural-language record of experiences and synthesise reflections from it [genagents]; ACE carries the Smart Zoi mechanism (1) [nvace].

Risk register

Debt register

Risk	Likelihood x impact	Mitigation
Motion matching is measured by eye and shipped by feel	probable x high	NP17's referee publishes foot-sliding permil with an interval and NP1's done rule requires that number to fall against the current page
A stub carrying a contract symbol flips a watch cell green with no capability behind it	possible x high	every rung names a neg-control and a fixture that can fail; the flip is the receipt, the gate is the proof
Watch contracts on nx_wasm_craft are owned by another lane and ship on its cadence	probable x medium	this board only measures; the contracts are named here and the symbols are the handshake, never an edit to that organ from this lane
The deterministic integer sim is broken by a float-shaped import	possible x high	every done rule above repeats the T4 checksum condition; a rung that loses determinism is refused
Intelligence is built before the body walks and the operator's complaint stands	probable x high	the ladder puts M0 first and NP7 depends on routing, so no village ships on a body that cannot walk around a house
A world rung is read as a nishi-browser rendering promise	possible x medium	npcai rungs deliver NPC behaviour into the sovereign-emitted world page -- NishiLang source compiled to wasm plus a page emitted by nx_game_page_emit, whose DEFAULT render is the sovereign framebuffer path that nx_sovworld_gate holds as law, with WebGL2 and WebGPU as opt-in last-mile paths for Chrome-class browsers; the native nishi-browser render of that page is the browser board's contract, not this one's

Id	Sev	What it is	Unblock
npcai-page-thresholds-literal	4	The idle hysteresis thresholds (0.03 enter, 0.15 leave) and the 400 ms release are literals inside the emitted page in nx_game_page_emit; the operator's own tuning history shows a single shared threshold was the defect once already.	NP1 retires them: a matched pose has no threshold. Until then they belong in a conf row read at emit.
npcai-pose-contract-unconsumed	5	mob_pose declares six pose ids and the served page reads none of them (mobpose absent from the 74 doors the page calls, measured 2026-08-27), so sleep, flee and sit render as the walk clip or the held stand.	NP3.
npcai-libs-unimported	5	nx_pathfind (pf_astar) and nx_char_ai (bt_tick, fsm_step) exist and nx_wasm_craft imports neither; nx_char_ai_gate and nx_footplant_gate are BUILT-UNPROMOTED; nx_sovworld_gate and nx_wasm_thirdperson_gate are PROMOTED-UNREGISTERED (nx_catalog 2026-08-27).	NP4 composes pf_astar; promote and register the four gates through nx_organ_ship and the register lane, then re-read nx_catalog until they read LIVE.

On these two registers. Rows are declared in the domain's plan file and carry the debt id, which is the join key back to the sovereign debt plane — that plane, not this page, is the authority on state. Reconciling them automatically (the regen reading the plane and refreshing these rows) is a named, owed rung; until it lands, treat an id here as a pointer to look up, not a status to trust.

Honest verdict. Honest position, measured 2026-08-27 from the served page and the engine source. The beach girls have an inner life the field mostly lacks -- integer needs, a nine-reason thought ledger whose mood is always decomposable into its reasons, gossip that decays into rumor, inherited bold-or-shy personality with proxemics and an F-formation ring, a friendship bond that survives the save -- and they move like a prototype: one walk clip whose phase is driven by distance moved, one held stand pose with a hand-tuned idle hysteresis, straight-line nudges with a ground query, no routing, no avoidance, no foot lock, no motion matching, no physics. The pose contract (sleep, flee, sit) is declared in the engine and the page does not read it, so a sleeping girl plays the walk clip. The behaviour layer is one utility argmax per NPC over needs and smart-object advertisements with night forcing rest; there is no schedule, no planner, no reservation, and the A* and behaviour-tree libraries the estate owns are not imported by the live world. The field: UE 5.8 ships motion matching as query-based pose selection over a database inside the Pose Search plugin [@ue5mm], Behavior Trees over a Blackboard [@uebt], StateTree as a hierarchical state machine with selectors [@uestatetree], Smart Objects used through a reservation system [@uesmartobj] and MassEntity for crowds [@uemass]; Godot ships the same shape as AnimationTree with root motion [@godotanimtree]; the physics-based controller line runs DeepMimic to AMP to ASE to CALM to PHC to MaskedMimic [@deepmimic] [@amp] [@ase] [@calm] [@phc] [@maskedmimic] and in 2026 InterPrior and MaskAdapt [@interprior] [@maskadapt], packaged by NVIDIA as ProtoMotions with a general tracking policy trained on about 142K motions [@protomotions]; NVIDIA ACE ships on-device SLM agents with a Game Agent SDK and UE5 plugins announced at Unreal Fest 2026 [@acesdk] and Qwen3-8B on device [@aceqwen]; inZOI shipped Smart Zoi on a 0.5B Minitron model that plans, acts and reflects at the end of each day [@inzoi] [@nvace]; Fable's Living Population is over 1,000 handcrafted NPCs with routines, jobs, beds, memory and reputation judged through each character's own values [@fablexbox] [@fableiv] [@fablevgc] [@fablepop], due 23 February 2027 [@fablewiki]; Generative Agents set the observe-plan-reflect architecture [@genagents] and NCP-Bench measures that even the best model keeps its narrative commitments only 42 percent of the time after 20 turns [@scriptbench]. What the estate genuinely has that the field does not: the ledger is integer and deterministic so a world replays bit-identically, the mood is inspectable to its reasons, and the gossip carries a confidence that decays and flips -- no rival page describes rumor as a mechanic. The critical path is movement first: motion matching, foot lock and routing before any more intelligence, because the operator's complaint is what the eye sees first.
