 The system operates across two temporal scopes that correspond to the organism's activity cycle.
 
-During the **DAY**, the organism is acting in the world and the neural system is processing experience. At the fastest timescale — milliseconds — individual synapses are transmitting signals, calcium is flowing, vesicles are releasing. At the intermediate timescale — seconds to minutes — patterns of activity are building up traces within each compartment: residual calcium encoding recent firing history, possible tagging variables accumulating evidence of sustained recruitment, dopamine transients arriving and intersecting with local eligibility windows. All of these traces are graded, decaying, and reversible. No permanent structural change occurs during DAY. The architecture is fixed and the system operates within it.

 The key DAY event is **tagging**: the coincidence of local eligibility — the component was recently and significantly active — and global validation — the organism-level neuromodulatory signal says this activity was worth preserving. When both coincide within the decay window of the local trace, a tag is set. The tag is the DAY scope's record of what the organism found significant. It is not binary — it is graded by how strong the activity was and how strong the validation was — and it decays slowly, surviving the full DAY scope to reach NIGHT.

 The entire system is fundamentally an **integration machine** operating across space and time simultaneously.
 
-In space, it integrates from the molecular level — calcium ions, receptor phosphorylation states, vesicle docking — through the synaptic level — pre, post, and astrosynapse cooperating — through the cellular level — soma integrating thousands of synaptic inputs — through the circuit level — populations of neurons collectively representing experience — to the organismic level — the VTA and locus coeruleus assessing the global significance of what is happening. Each level provides information that the level below cannot generate from within itself. The organism's assessment of significance — dopamine — is not computable from the synapse's local activity. The synapse's coincidence detection — the bAP meeting the NMDA calcium signal — is not visible at the organismic level. Both are necessary. Neither is sufficient alone.

 In time, it integrates from the millisecond scale — individual spikes and calcium transients — through the second-to-minute scale — spike trains and trace accumulation — through the hour scale — tag persistence and protein synthesis — through the day-night cycle — structural commit and budget replenishment — through the multi-day scale — queued deficits resolved across consecutive nights and structural consolidation completed. Each timescale feeds forward into the next: what happens in milliseconds determines what the traces look like over minutes, which determines what gets tagged over hours, which determines what gets structurally committed over nights, which determines how the system responds to experience over weeks.
