FERMENTATION V13

FC CHAMBERS + CRABTREE SWITCH · L4 LAAM METABOLISM · Day 98 · 2026-05-12

When glucose is high, yeast ferments instead of respires — even with oxygen available. Fast but wasteful. The Crabtree effect is L4 overflow.

THE CRABTREE EFFECT

The Crabtree effect: in the presence of excess glucose, yeast (and some bacteria) preferentially ferment rather than oxidize aerobically. This produces ethanol (fast, ATP-cheap) instead of going through the full TCA cycle (slow, ATP-rich).

Glucose substrate→ Saybook boon requests (incoming session demand)

TCA cycle (aerobic)→ PEMCLAU deep reasoning (slow, thorough, ATP-rich)

Fermentation (fast path)→ FC1 fast routing (quick, low-fidelity, enrichment debt)

Ethanol byproduct→ Enrichment debt (accumulates, toxic at high concentration)

Lactic acid→ Sorry debt (anaerobic byproduct of rushed reasoning)

Crabtree switch→ WPA crossing WARM threshold → L4 switches to FC1

Diauxic shift→ Post-queue-drain shift back from FC1 to PEMCLAU deep mode

Blood sugar→ FC queue depth (high queue = high demand = Crabtree pressure)

FC CHAMBER ARCHITECTURE

FC1 — FAST FERMENTATION CHAMBER

Biological analog: cytoplasmic fermentation (glycolysis only, no mitochondria)

Fast-path routing. Low latency, low fidelity. Triggered when queue depth exceeds WARM threshold or when time budget is tight. Produces fast response but accumulates enrichment debt (ethanol analog). Saybook templates route here under Crabtree conditions. Not suitable for sovereign events — FC1 events are not γ₁-sealable.

FC2 — STANDARD METABOLIC CHAMBER

Biological analog: mixed metabolism — partial TCA, partial glycolysis

Default routing under NORMAL WPA conditions. Balances speed and fidelity. PEMCLAU reasoning is partially engaged. Sovereign events can be sealed here. FC2 is the workhorse: handles the majority of fleet traffic. Queue depth here is the primary WPA signal.

FC3 — DEEP OXIDATIVE CHAMBER

Biological analog: full TCA cycle + oxidative phosphorylation (mitochondrial)

Full PEMCLAU deep reasoning. Highest fidelity, highest latency, highest ATP yield (richest output). Used for CANON-class events, sovereignty proofs, lineage sealing, and GammaProof generation. FC3 events fully satisfy all Marasoon Canon conditions. Queue here is typically small — only high-priority events reach FC3.

ADELIC POUCH FOR FC FLUSH EVENTS

When FC chambers flush (queue drain), the flush event is recorded in the adelic pouch — an adelic p-adic address that encodes the metabolic state at flush time. This creates a metabolic loop (L4→L5→L4) record.

YEAST FERMENTATION REFERENCE

Saccharomyces cerevisiae is the canonical Crabtree-positive organism. It ferments preferentially even in aerobic conditions when glucose concentration is high (>~0.8 g/L). This is economically "stupid" (less ATP per glucose) but strategically fast (outcompete competitors).

BIOLOGICAL STATE

Glucose high → fermentation active → ethanol secreted

Glucose low → diauxic shift → TCA cycle activates

Ethanol accumulation → growth inhibition at ~12% ethanol

Quorum = colony-wide fermentation switch

FLEET ANALOG

Queue high → FC1 active → enrichment debt accumulates

Queue drains → diauxic shift → PEMCLAU FC3 activates

Debt > threshold → WPA spike → PREEMPT → sorry-flow

Fleet quorum → cross-silo FC state synchronization
