Tripartite Synapse — Pseudocode v13
Companion:
tripartite_synapse_v13_biology.md. Changes from v12: (1) per-spike calcium deposit (frequency stays emergent, not a parameter) (2) BEHAVE splits FUEL shortfall (→ endurance) from OCCUPANCY shortfall (→ STD) (3) endurance feedback term only where a retrograde signal actually arrives (4) TRACE absorbs EVALUATE → seven-group grammar (5) parameter declarations completed (ship_cost, ACh_gain, NIGHT block) (6) shipment is a transit-delayed flow; every flow has a timescale (7) all group labels are standalone headers at one column
Functional groups (seven-group grammar)
RECEIVE take in resources + signals that arrived from outside (boundary: in)
TRACE maintain the trace hierarchy — deposit fast trace; accumulate
possible_tag + endurance_need; stabilize tag on coincidence
ADJUST compute local operating parameters from structure + traces + modulators
BEHAVE the component's defining action, within both ceilings
EMIT send out — signals (messages) + resources (shipments) (boundary: out)
RECOVER refill own private pools consumed by behaving
DECAY let traces recede, closing their windows
EVALUATE merged into TRACE: judging a behavior is always maintaining a trace, whether or not a trace is written. BEHAVE and EMIT stay separate — EMIT is the output half of the locality interface (RECEIVE/EMIT are the only boundary crossings). TRACE spans all timescales: the soma's inactivation, adaptation, and nuclear-Ca deposits are all TRACE. Order within a context follows data dependencies; TRACE reads/writes whatever trace state is current.
EVERY FLOW HAS A TIMESCALE. Decay relaxes toward 0 over τ; creation/arrival relaxes toward a
target over τ — the same first-order operator. Within-step writes are the special case τ ≪ Δt.
Rate-limited inflows (fill/refill/flux·Δt) carry their τ implicitly; shipment carries an
explicit transit delay (see transit).
Conventions
SCOPE = {DAY, NIGHT} CONTEXT = {AP, NOT_AP, bAP, NOT_bAP, CONTINUOUS}
DAY budget · fast_trace · possible_tag · endurance_need
BRIDGE tag (POST: CANDIDATE→STABLE)
NIGHT energy (not recoverable) · material (recoverable) · structure · budget_ceiling
LOCALITY only local state + arrived signals; no component reads another's internal state.

One-view summary
SEVEN-GROUP GRAMMAR, TWO TIMESCALES
RECEIVE · TRACE · ADJUST · BEHAVE · EMIT · RECOVER · DECAY
DAY grammar on OCCUPANCY within two ceilings (structure=strength, budget_ceiling=endurance)
TRACE yields two evidence streams from local state + arrived signals:
fast_trace + dopamine → tag (strength)
FUEL shortfall + interrupted LOCAL success → endurance_need (endurance)
OCCUPANCY/structure/timing shortfalls → short-term depression (NOT endurance)
NIGHT same grammar on the CEILINGS:
tag → structure ; endurance_need → budget_ceiling ; both draw one pool (compete)
unmaintained ceilings decay → recovered material funds the rest
FLOWS every flow has a timescale: decay relaxes toward 0 over τ, arrival toward a target
over τ; shipment is transit-delayed; rate-limited inflows carry τ implicitly.
LOCAL every group uses only own state + arrived signals; RECEIVE/EMIT are the only crossings.
