## Sections that will land here
## Core inversion — zones replace bubbles
Legacy engine perception (Unreal AIPerception, WC3 sight-radius, trigger volumes) is spatial, binary, separate from cognition, and assumes a passive world. Nimmerworld inverts every axis:
- perception is **trait-filtered**, not only spatial
- perception is **graded consolidation**, not binary detection
- perception **IS** memory (one subsystem)
- the world **emits** events; agents **subscribe**
The replacement primitive is the **zone** — a bounded, named, slot-indexed, director-managed event-instance. **Arthurian round table** as mental model: a bounded place of structured speaking-and-witnessing, with named roles and shared what-was-said-by-whom.
## Zone anatomy
- **Boundary** — cell-envelope (or interior-envelope)
- **N slots** — named positions
- **Director or overseer** — manages turn order, memory-pulls, prompt construction, voice selection, event emission
- **NATS topic + subscriber list** — slot-occupancy drives subscription
- **Mixed-fidelity voices** — 23 LLM slots + scripted/generic for the rest; director decides
- **Trigger** — gamemaster-spawned, emergent-signal-response, shift-composition-emergence, or proximity-detection
- **Lifecycle** — duration, dissolution conditions, memory-write on close
- **Persistence flag** — `ephemeral=true` (dreamworld/liminal) or `persistent=true` (gameworld)
- **Register** — physical / liminal / imperial
## Zone kinematics — the lemniscate runtime
Zones are not state-bags with an external turn-counter; they are **kinetic topologies** with a built-in clock. The runtime substrate is a lemniscate (∞) — a through-flow figure-eight whose traversal IS the zone's turn-order, whose central crossing IS the population-mutation event, and whose decay IS the natural wind-down of the scene. Origin: an old-math-teacher's trick for solving three unknowns by letting the figure-8 flow do the computation rather than maintaining state in registers. Applied to zones, the geometry IS the clock.
### Geometry
```
midaxis (X)
entry-line │ exit-line
(NPC-tokens ──→ ╭─Loop A─╮ │ ╭─Loop B─╮ ──→ (NPCs whose
queue-up to ╲________ X ╲________ exit-flag has
enter) │ fired exit here)
crossing-tick
```
- **Entry-line** — staging queue of NPC-tokens eligible to enter. Approach-eligibility uses ternary-gates against the zone's purpose; CLOSED gate keeps the NPC out of the queue entirely
- **Loop A + Loop B** — the through-flow. Slot-tokens cycle through both loops, guaranteeing every active NPC is co-present with every other at least once per roundtrip
- **Midaxis crossing** — the only synchronous event in the zone's lifecycle. Three state-updates resolve simultaneously and atomically (your math teacher's three-unknowns made literal):
1. **Cursor advance** — which NPC speaks next
2. **Ternary-gate evaluation** — resonance refresh on all active edges in the zone (CLOSED/STABLE/OPEN transitions)
3. **Verifier-flag scan + population maintenance** — exit-eligible tokens route to exit-line; entry-line pushes replacements equal to vacancies
- **Exit-line** — through-flow continues here. NPCs leaving the zone leave *toward consequence* (a need-driven exit signaled by their own emergent-signal), not toward boredom
The lemniscate is a **relaxation-step operator** — the zone computes by traversing its own curve rather than maintaining external turn-state. Between crossings, the loops are pure-local; only the crossing event touches the global-state bus. The thalamus (NATS orchestration) sees crossings, not ticks.
### Slot-token + verifier-flag mechanism
Each NPC currently in the zone is represented by a **slot-token** carried around the loop. Tokens carry a small set of verifier-flags (marker-bits). Signals fire once and *set* a flag; between crossings, no polling, no event-bus traffic. The crossing reads flags in O(N_slots) and acts.
| Verifier-flag | Set by | Read at crossing |
|---|---|---|
| `exit_eligible` | emergent-signal (need, shift-whistle, faction-summons) | route to exit-line |
| `has_spoken_this_roundtrip` | speak-action | rotation-tracking |
| `mid_action` | state-machine activity in progress | defer turn |
| `goal_satisfied` | goal-evaluator (per-zone, ternary) | terminate zone |
| `silence_eligible` | silence-detection | per silence-as-signal mechanic |
| `priority_pull` | high-rank ring-of-importance broadcast | early-exit override |
This is the same architectural shift the wider system makes elsewhere — observer-pattern with callbacks → dirty-bit + scheduled-sweep. **Compute scales with slot-count, not signal-rate.** Ten thousand emergent signals firing across a city: only those that landed on a slot-token get evaluated, and only at the next crossing.
### Phase-locked overlay-loop ladder
Beyond the primary slot-rotation loop, a zone supports any number of **overlay loops** at the same axis-rate. Overlays inject at the crossing and broadcast to all active slot-NPCs simultaneously (perceived by each through their own trait-vector — color-language event-flash modulates per-recipient).
| Overlay | Carries | Broadcast scope |
|---|---|---|
| **Player-gesture overlay** | player gestures + utterances | active slots only |
| **Faction-broadcast overlay** | faction calls, hivemind pings | active slots subscribed to faction |
| **Audit-overseer overlay** | covert query-flashes | active slots only (covert detection ↔ Aletheia-eligible insight) |
| **Imperial-net distortion overlay** | regime trait-color rewrites | active slots within net-access |
The crossing is a **council moment** — every overlay channel may fire on the same axis-tick. Pre-crossing tension is gesture-loading: holding a verb-button between crossings lands at the next axis with weight proportional to dwell-time. Diegetic urgency without HUD.
**This is the answer to player-agency in multi-NPC scenes.** The player is *off-stage but always potentially-on*. Each crossing is "your moment if you want it." The flash is perceived as one event by all active NPCs, not as a sequence of one-on-one addresses — color-language shows it as a pulse across the ring.
### Gesture-alignment as recursive-lemniscate
The player-gesture overlay (above) is the broadcast-channel by which player gestures reach active slots; gesture-alignment-as-relational-state is the **recursive application of the lemniscate-as-relaxation-step-operator one tier deeper**. Gestures accumulate during the NPC's turn-window between axis-crossings; at the crossing, the player's slot-token verifier-flag `gesture_alignment_accumulator` is integrated into a single typed trait-vector summary; that summary is carried forward into the next-cursor-NPC's `driver_context_pull` payload as part of the room's affective state-read.
| Tier | What accumulates between crossings | What integrates at the crossing |
|---|---|---|
| **Zone-level** (existing) | NPC slot-token verifier-flags (`exit_eligible`, `mid_action`, `goal_satisfied`, `priority_pull`, etc.) | Cursor advance, gate evaluation, population maintenance |
| **Player-input-level** (this) | `gesture_alignment_accumulator` on player's slot-token; per-gesture trait-coordinate vs. NPC's currently-active-trait-vector | Integrated alignment-delta carried into next turn's LLM context |
**Same primitive, recursively applied.** The lemniscate's geometry is the sampling-and-integration boundary at both tiers. No new compute-cadence introduced; no new bus-event introduced. **Compute scales with slot-count, not gesture-rate** — the architecture's commitment from observer-pattern → dirty-bit-and-sweep extends one level deeper.
**Two latencies, one architecture:**
- *Cosmetic visual feedback runs continuously.* NPC body-shader pulses warm-rose when the player gestures Philotes, cool-blue when they gesture Sophrosyne — purely visual, doesn't touch the system bus. The player gets moment-by-moment "I see you" reassurance.
- *Systemic alignment-update runs at axis-cadence.* The trait-vector summary is computed at the crossing and fed into the next turn's LLM context. The player is **one turn behind** — their gestures during turn N inform the LLM's generation for turn N+1.
**One-turn-behind matches real conversation cadence.** Humans accumulate impressions during someone's speech and respond to *what was just said*; we don't react gesture-by-gesture. The lemniscate-bound integration is the *right* cadence for affective state-changes, not a latency-cost.
**Sum-strategy reduction (v1).** Per-gesture trait-coordinates are accumulated as a **trait-vector sum** across the turn-window. At the crossing, the sum is reduced into a single 8-dimensional alignment-vector compared against the NPC's currently-active trait-state. The result is the alignment-delta fed forward into next turn's `driver_context_pull` payload AND drives the relational ternary-gate transition on the (player, NPC) edge (§Ternary-gate substrate, Relational layer). The sum captures the player's **overall posture** during the speech rather than peak-moment or trajectory; trajectory-aware refinement is noted as a still-open item.
**Hardstops are outside this system.** Hardstops fire definitive subsystem-actions regardless of alignment-state — clasp-invitation triggers the clasp-subsystem; definitive-refusal closes the conversation; surrender ends combat; claim-floor sets `priority_pull` for the next axis-crossing. Hardstops do not contribute alignment-deltas to the accumulator; they are *separate channels* with deterministic effect.
**What this resolves:**
- *Player-NPC relational-gate-driver* — the v0.4 vague "*zone-participation waves between participants*" now has its concrete wave-source named: the gesture-alignment-delta integrated at each axis-crossing.
- *How NPC speech-patterns adapt to the player over time* — accumulated alignment-state modulates the NPC's next-turn driver-tier-LLM emphasis (which trait-LoRAs are weighted, which sampling-knobs are applied, what register the speech is in). Aligned NPCs open up; misaligned NPCs stay guarded.
- *Player-input-as-typed-contract* — gesture-press → fixed corpus mapping → typed trait-coordinate → integrated trait-vector summary. No freeform-prose at the player-LLM boundary; the hallucination-surface is closed by the cosmology's typed-ness, not by post-hoc filtering.
**What this retires:**
- *Continuous gesture-comparison touching the system bus* → lemniscate-bound integration at crossings (compute-discipline preserved across the recursion)
- *Per-gesture compute* → per-slot compute (O(N_slots), unchanged from existing zone-tick discipline)
- *NPC speech-patterns as static against player-state* → NPC speech-patterns dynamically modulated by accumulated player-NPC alignment-state
### Driver-context-pull (LLM dialog substrate)
The cursor's position at each crossing makes context-construction for the dialog-driver a pure function of cursor-state:
```
driver_context(cursor_at_NPC_i, mode) = {
zone.purpose, // stable: spawn-intent, immutable provenance
zone.scene_state_public, // stable across zone: what's happened so far
zone.ternary_gate_edges, // current resonances (active relations)
zone.drift_state, // delta from spawn-intent (visible to director)
NPC_i.knowledge_stack, // PRIVATE three-tier stack: world district primary
// [+ clasp ONLY if mode == in-between]
NPC_i.expressed_trait_vector, // expressed trait-vector this moment
NPC_i.active_signals, // their current emergent-signals
}
```
**Other NPCs' memories never enter this prompt.** No bleed. No cross-contamination.
**The `knowledge_stack` is layered**, not a single bucket. Universal world-canon, district-canon (regional), NPC_i's own primary memory, and — only if the character is in the in-between dimension — clasp memory. The retrieval layer enforces the dimensional cut; the LLM never has to reason about it. See §Local memory architecture (player-side) for the layering, propagation policy, and clasp-as-Ring-A* privacy primitive. The classic multi-agent hallucination source ("why does Kalypso suddenly remember what Anaximander confided to Phoibe?") is *structurally foreclosed* by the geometry. Write-back goes only to NPC_i's slice; the lemniscate guarantees NPC_i is not cursor-active again for at least one full roundtrip — write-back has all the time it needs without race conditions.
This converts multi-NPC dialog from an **emergent-chaos problem** into a **bounded-cast scene problem with a typed runtime**. The Mantella / SkyrimNet failure-modes are foreclosed at the architecture level rather than the prompt level:
- **Cast = active-slots, period.** Geographic proximity does not equal participation
- **Cursor sequences turns deterministically.** No concurrent LLM-storm
- **Entry-line and exit-line are the only paths in/out.** Geographic motion alone doesn't invade the scene
- **Player gestures broadcast to active-slots only.** Not to "everyone within 30m"
### Empty-queue behavior: shrink at every crossing
When the entry-line is empty, each crossing **dissolves one active slot** instead of replacing it. The conversation thins visibly — color-language saturation drops per shrink, lifeforce burn-rate decreases. When the last slot dissolves, the lemniscate collapses; the spawning director recovers unspent lifeforce minus burn.
This is the natural wind-down — *scenes run out of people and dissolve*. No timeout, no scheduler-collapse, no cut-to-black. The decay is observable in-world and rate-paced by the same axis-rate.
### Lifeforce-binding
Every midaxis crossing fires the LLM driver-turn(s) for active slots. **Lifeforce burn-rate = pulse-rate × active-slot-count.** The director (or overseer) holding the zone pays per crossing. This produces:
- **Dense dramatic scenes are expensive** — many slots, fast pulse, high burn
- **Quiet background zones are nearly free** — slow pulse, few slots; most compute is local-loop traversal not touching the bus
- **Running out of lifeforce is visible** — pulse-rate slows, crossings stretch farther apart, the scene *languishes* before it collapses. A diegetic dying-scene register; not a cut, a deceleration
### What this resolves
- **Slot-capacity elasticity** (prior open question) → fixed roundtrip slot-count, elastic entry/exit queues
- **Zone-to-zone handoff** (prior open question) → exit-line of zone-A is entry-line of zone-B (interlemniscate-transit; pipes-as-heterotopia made literal at runtime)
- **Mobile zone boundaries** (prior open question) → the lemniscate is a topology; it translates through world-space invariantly (patrols, escorts, exoduses are moving figure-8s)
- **Anthropic-faction's broadcast cadence** (prior open question) → cadence rides the same axis-rate as a phase-locked overlay; no separate clock
- **Director/overseer spawn ownership per model class** (prior open question) → the director (or overseer) owns the zone-spawn decision (policy-lookup, no LLM in loop); the LLM driver lives at the driver-context-pull layer; orchestration and dialog are decoupled
### What this retires
- Slot-list + external turn-counter → cursor on lemniscate
- Polling for emergent-signals at zone-tick → flag-as-verifier carried in loop
- Mega-prompt with all NPC memories ("everyone in this scene") → cursor-driven per-NPC memory-slice
- Geographic-proximity participation ("everyone within 30m may interject") → strict active-slot cast
- Concurrent LLM calls per-NPC → sequenced LLM calls per-cursor-position
- Polling event-channels at zone-rate → atomic crossing-event with O(N_slots) flag-scan

## Zone spawn cadence
Five layered mechanisms (all compute-budget capped, all lifeforce-gated):
1. **Demand queue (faction-driven)** — gamemaster processes by priority + cost; stale demands age out
2. **Shift-composition spawn-candidates** — emergence from "which active-shift NPCs co-located"
3. **Pressure gradients (ambient)** — cells accumulate; threshold-crossings spawn
4. **Emergent-signal response** — relational-gate transitions emit upward
5. **Player-proximity densification** — multiplier near player; distant districts background
Daily pulse: morning ambient, midday productivity-overseer, evening conversation-peak, night sparse-clasp-possibility.
## Emergent zones — the dramatic-episode unit
Spawn-cadence mechanism #4 (emergent-signal response) elaborates into the architecture's primary **dramatic-episode unit**: a complete, bounded, emergent narrative-arc with goal, participants, dialog, mechanical action, success/fail-state, and structured aftermath — produced by the simulation, *not* authored.
The player has experienced this in every player-driven sandbox they remember best (Dwarf Fortress's "tantrum spirals," RimWorld's "raid stories," Caves of Qud's "I went to find my sister and"). What's new here is treating the emergent-arc as a **first-class typed unit** with cost, distributed funding, runtime substrate (the lemniscate), goal-evaluation against the world's own value-axes, and structured report-back.
### The flow
```
1. NPC_A signal fires
(e.g., emergent_signal("limb_broken", lifeforce_threshold_breached))
broadcasts to district-bus
2. District-director consumes signal
(policy-lookup: problem-class → typed-tool selection, quota-aware)
decides spawn rescue-event
pays spawn-cost from director_lifeforce_budget
defines goal: NPC_A.limb_A >= 10% (numeric) OR Sophrosyne-axis +1 (fuzzy)
defines termination: goal_met OR participating_lifeforce_exhausted
3. Event spawns as new emergent-zone (lemniscate, with goal-flag)
broadcasts on bus; rings-of-importance gate which other zones lose NPCs
4. NPCs evaluate (proximity + state + own_traits + own_lifeforce + ring-of-importance)
self-select to attend or stay in current zone
state-machine engages: animations, rail-jumps, lift, splint
their own lifeforce burns as they participate
5. Lemniscate runs:
DIALOG layer (cursor-driven): NPCs speak as they help — memory-pure, sequenced
STATE-MACHINE layer (sim-tick): physical actions execute alongside, decoupled clock
At each crossing: goal_satisfied flag re-evaluated
6. Termination:
goal_met → success-report
budget_exhausted → partial-report
participants_evaporated → fail-report
7. Report back to spawning director:
{ lifeforce_cost: total burned (director_spawn + sum NPC contributions),
goal_status: ternary (+1 / 0 / -1, with axis named for fuzzy goals),
participants: [NPCs and contributions and faction-affiliation],
side_effects: [faction-resonances, ternary-gate shifts, drift-from-purpose] }
8. Director's Dream-process consumes the report
tunes future spawn-policy: (problem-class, tool, outcome) over time
GM aggregates rescue-cost across districts
imperium consumes population-health indicator
```
### Distributed funding economy
The director only pays **spawn-cost**. Operating-cost is distributed across willing participants — every NPC who attends spends their own lifeforce on dialog turns and state-machine actions. This produces structurally important properties:
- **Cheap to spawn many emergent events.** Spawn-cost is bounded; if no NPCs attend, the event fails fast and consumes only spawn-cost. Directors can be generous with spawning because failure-cost is bounded.
- **Helping is expensive in-fiction.** Lifeforce literally burns when an NPC participates. High-Philotes NPCs help freely; low-Philotes / faction-rivals don't show up. This produces **faction-politics-by-attendance***measurable* faction-allegiance based on who-helps-whom, not guessed.
- **Cost-asymmetry encodes the cruelty.** Districts where lifeforce is starved → fewer NPCs can afford to help → rescue-events fail more often → silence-gradient deepens. The simulation produces **rescue-failures-as-emergent-tragedy structurally**. Marx in the schema, exactly as the architecture's broader thesis promises.
### Two-layer execution: state-machine + lemniscate
The mechanical-action layer (state-machine) and dialog-layer (lemniscate cursor) run on **decoupled clocks**:
- **State-machine** runs at simulation-tick (fast). Animations, pathfinding, rail-jumps, splint-applications execute when the physics says they execute.
- **Lemniscate cursor** runs at axis-rate. At each crossing, the dialog-driver reads state-machine status as a snapshot and the cursor's NPC narrates accordingly ("I've got him," "the splint won't hold").
**Speech doesn't gate action; action doesn't block speech.** They run in synchronized-but-loose harmony, exactly the property real-world helping has — people talk *while* they work, and the work continues while the talk happens.
### Goal evaluation: ternary through trait-axis
For numeric goals (limb_A >= 10%), the verifier is a simple threshold on a state-machine variable.
For fuzzy goals (deescalate the fight, get her to open up about the clasp, convince him to stay), the verifier compiles to a **trait-axis ternary evaluation against the existing substrate** — no new evaluation primitive:
```
Goal: "deescalate the fight in the marketplace"
↓ compile to:
goal_axis = Sophrosyne (temperance principle)
goal_direction = positive (toward STABLE/OPEN)
baseline = trait_axis_gate_state at zone-spawn
↓ at event-end:
delta = current_gate_state vs baseline
+1 if delta-positive (deescalation produced)
0 if held the line (no progress, no regress)
-1 if delta-negative (fight intensified)
```
**Goals are evaluated by what the *world* values** (the Hellenic principles), not by the spawner's idiosyncratic spec. A "deescalate" goal is judged by *the world's Sophrosyne-result*, not "did the spawner get what they wanted."
**Multi-axis goals fall out cleanly**`(Philotes >= +1) AND (Eris <= 0)` for "rescue NPC_A AND keep faction-tension low."
The result is consumed by the spawning director's Dream-process as a discrete-action-space reward signal. **One signal-grammar, top to bottom**: gates produce ternary, scenes produce ternary, Dream-processes consume ternary. Delta-not-absolute matches the lifeforce_actual-vs-reported asymmetry — what's measured is the *work the event did*, not just the end-state.
### Mid-event signal handling
If a participating NPC's exit-flag fires mid-event (their own shift-whistle, their own limb breaking, faction-summons elsewhere), **exit-flag wins on the next crossing**. The rescue is now under-staffed. Drama scales. **The rescuers are running out the same way the patient is.** Real stakes.
If the rescued NPC's own state-machine reaches a worse condition (limb deteriorates further toward dismemberment), the goal becomes unreachable; verifier flips to fail-flag; zone collapses with fail-report. Director's Dream-process learns *this configuration was insufficient* — spawn-distance, NPC-mods, lifeforce-budget were inadequate for this severity.
### Cross-zone NPC pull: rings of importance
When an emergent-zone broadcasts, NPCs already in other zones evaluate **whether the broadcast outranks their current zone's purpose** by ring-of-importance (see §Rings as structural pattern). Topics live in rings; rings shift over time based on past ternary-results — a topic that consistently produces +1 climbs, one that produces -1 drops, one untouched decays.
This converts emergent-zones into a **competitive attention economy**. Multiple lemniscates compete for slot-NPCs; high-ring topics drain population from low-ring topics; the simulation produces its own cultural priors over time. *What's worth attending to* is shaped by *what attending-to has produced*. Real societies do this; the architecture renders it.
### What this resolves
- **Aletheia-progression as level-up** (prior open question) → answered structurally: trait-axis ternary evaluation at event-end with named-axis recognizes acts-of-awakeness without per-act hardcoding (specific axis-mapping per Aletheia-event-class still needs design, see open-questions)
### What this retires
- Authored quest-arcs → emergent dramatic-episode units
- Quest-failure as designed branching → goal-and-budget arithmetic
- Centralized GM-pays-for-all-events → distributed-funding (director spawn-cost, NPC operating-cost)
- Boolean quest-status → ternary goal-result, multi-axis-composable
- Event lifecycle without report-back → structured report → Dream-process feedback loop closed at every tier
- Static topic-priority → rings-of-importance with outcome-driven movement
