-## 5. Scarcity Decides — Collaboration by Day, Competition by Night
+## 5. Participation Under Scarcity — The Allocation Loop
 
-How components relate to one another is not an independent fact; it follows from what is scarce.
-This specializes the principle to *how do components relate?* — and it unifies conservation,
-selection, and the collaboration/competition character of the two scopes into one causal chain.
+How components relate, what gets consolidated, and why the two scopes have the character they do all
+follow from one deeper thing: a scarce resource, allocated by past participation, spent on present
+participation, traced, and feeding the next allocation. This is the system's economy, and it is a
+single self-reinforcing loop that never stops — it only alternates which resource and which arena is
+active. Several principles once stated separately are facets of it.
 
-**Two conserved currencies, two rules of flow.** Energy ratchets: it is spent irreversibly, the
-arrow of time in the model — a component that burns energy into structure cannot get it back.
-Material circulates: it is freed by one component and reclaimed by another, conserved as it moves.
-Scarcity of both forces choice — two ceilings (structure and endurance) compete for one finite
-night pool, and what is not maintained drifts back down.
+**The loop.** In each scope a component holds a *limited resource*; it receives that resource in
+proportion to how it *participated before*; it *spends* it participating now; that participation is
+*traced*; and the trace determines its *next* allocation. Round and round:
 
-**Rivalry of the currency sets the relation.** By day the currency is information, which is
-*non-rival*: a bouton releasing glutamate does not use up the spine's ability to receive it; a trace
-here does not deplete a trace there. When producing for others costs nothing, the natural relation
-is **collaboration** — and the day is exactly that: each component acts so the next can act, releasing,
-integrating, clearing, passing activity along the chain, co-producing the pattern and the tags. By
-night the currency is material and energy, which are *rival and conserved*: every unit one component
-builds into its structure is a unit another cannot have, and the total is capped. When what one takes
-another loses, the natural relation is **competition** — and the night is exactly that: components
-contend for the shared pool, build what they win, and free what they shed back into contention.
+> **resource (scarce) → allocated by past participation → spent on present participation → traced →
+> allocates the next resource.**
 
-**But night's competition is adjudicated by collaboration.** The relation is subtler than "day
-collaborate, night compete." The replay that arbitrates the night's competition is itself a
-collaborative act: a pattern re-evokes only if every component along its loop is primed and ignites
-the next — mechanical coherence, a collaboration all the way around, one un-primed link breaking it.
-Participation — the measure that gates who gets to build — *is* a measure of successful collaboration
-in that re-enactment. So a component earns its share of the scarce material in proportion to how well
-it collaborated in replaying the pattern. Collaboration is primary in both scopes: by day it
-*produces* the shared, non-rival good; by night it *adjudicates* the competition for the rival one.
-The register is economic, not martial — components do not fight; they contend for a conserved
-resource, and the contention is settled fairly by a collaborative criterion.
+By **day** the resource is the component's action budget (vesicles, ions, fuel); it is allocated by
+the structure prior nights built (a stronger synapse acts more); it is spent acting in the world; the
+acting is traced (fast trace → tag). By **night** the resource is the component's own energy store; it
+is allocated by the tags the prior day earned (more tag, more energy, more chance to take part — but
+all must participate); it is spent participating in the replayed circuits, drawing the store down until
+the component gives way and another circuit surfaces; the participation is traced. Then day's trace
+(tags) allocates night's energy, and night's trace (what was strengthened) allocates day's future
+action — the two runs of the loop are coupled, each feeding the other. It is one loop, run on two
+resources in two arenas, coupled end to end.
 
-**Two competitions at two loci.** Within the night, competition appears twice, cleanly separated.
-*Within* a component, build and release contend over its own structure, arbitrated by participation:
-high participation builds (funded by the tag, a slice per cycle), low participation releases (freeing
-material, the tag untouched), and in between the component holds. *Between* components, this one and
-its peers contend for the shared material and energy during recovery. The internal tension (grow or
-shrink?) is settled by the replayed pattern; the external tension (can I get material?) is settled by
-contention with neighbors. Selection under scarcity is the sum of these: what survives a night has
-both earned its tag by day and won its material by night, and what neither participates nor is
-maintained returns to the pool. Selection is not a judge's verdict; it is what scarcity leaves
-standing.
+**Why scarcity is what makes participation informative.** This is the heart. If the resource were
+unlimited, every component would participate in everything and participation would carry no signal —
+there would be nothing to learn from "did you take part," because everyone always would. The *limit*
+is what makes participation a real choice under constraint, and therefore evidence. So scarcity is not
+a mere constraint to be worked around; it is the *condition of the signal*. What consolidates, at
+every scale and in both scopes, is simply **what participated when participating cost something**.
+Strengthening is nothing but the persistent record of costly participation.
+
+**Rivalry of the resource sets the relation — collaboration by day, competition by night.** The loop's
+*mode* depends on whether the resource is shareable. By day the currency is information, which is
+*non-rival*: a bouton releasing glutamate does not use up the spine's ability to receive it. When
+producing for others costs nothing, the relation is **collaboration** — each component acts so the
+next can act, co-producing the pattern and the tags. By night the currency is energy and material,
+which are *rival and conserved*: every unit one component draws is a unit another cannot. When what one
+takes another loses, the relation is **competition** — components contend for the shared pool. This is
+the old "scarcity decides the mode," now seen as one facet of the allocation loop: the rivalry of the
+resource sets whether present participation is shared or contended.
+
+**But the competition is adjudicated by collaboration.** The replay that arbitrates the night's
+contest is itself collaborative: a pattern re-evokes only if every component along its loop is primed
+and ignites the next — mechanical coherence, one un-primed link breaking it. Participation — the
+measure that gates who consolidates — *is* a measure of successful collaboration in that re-enactment.
+So a component earns its share of the scarce material in proportion to how well it collaborated in
+replaying the pattern. Collaboration is primary in both scopes: by day it *produces* the shared,
+non-rival good; by night it *adjudicates* the contention for the rival one. The register is economic,
+not martial — components contend for a conserved resource, and the contention is settled fairly by a
+collaborative criterion.
+
+**Two readings of participation: precision and stamina.** Because participation-under-scarcity is the
+one currency of consolidation, the two things a memory must be — well-aimed and durable — are two
+readings of it, not two mechanisms. **Strength** is participation in the *significance* sense: did the
+component take part in what mattered (the reward-gated tag, at the significance-deciding sites). It is
+precision — aligning well. **Endurance** is participation in the *sustained* sense: could the component
+keep taking part under load (the homeostatic need, everywhere). It is stamina — aligning long. One is
+dopamine-gated and local to the sites that decide significance; the other is load-driven and universal.
+But both are participation under a scarce resource, and both consolidate by the same loop; they are the
+precision and the stamina of a single project, not separate pathways bolted together.
+
+**Two competitions at two loci** (the night's internal structure). *Within* a component, build and
+release contend over its own structure, arbitrated by participation: high participation builds (funded
+by tag and material), low participation releases (freeing material), between holds. *Between*
+components, this one and its peers contend for the shared pool during recovery. The internal tension
+(grow or shrink?) is settled by the replayed participation; the external (can I get material?) by
+contention with neighbours. Selection under scarcity is the sum: what survives a night has both earned
+its tag by day and won its material by night. Selection is not a judge's verdict; it is what scarcity
+leaves standing.
+
+**Two conserved currencies, two rules of flow** (the substrate the loop runs on). Energy ratchets: it
+is spent irreversibly, the arrow of time in the model — burned into structure, it does not return.
+Material circulates: freed by one component, reclaimed by another, conserved as it moves. The night's
+finite pool of both is what forces the competition; the day's non-rival information is what permits the
+collaboration. The character of each scope is set by the conservation law of its resource.
+
+**Why the two scopes have the shape they have — the loop run twice.** The two-stroke rhythm of day and
+night is the allocation loop run in two arenas and coupled: the day gathers evidence (spends action
+budget, traces tags), the night consolidates it (spends energy, traces strengthening), and each
+allocates the other's next resource — day's tags buy night's energy, night's structure buys day's
+action. And the loop's own dynamics give the night its shape: early night, on unbuilt structure, the
+energy is spent fast on circuits that break (short replay); late night, on consolidated structure, the
+same energy sustains many completing circuits swept in turn (long replay). The night lengthens its
+replay as it builds the structure that lets participation last — the shape of the night is the progress
+of consolidation made visible, and it too falls out of participation under scarcity.
