Audio data compressiondepends onAuditory maskingEstablished
audio data compression depends on auditory masking.
Mechanism: Lossy audio codecs throw away masked sound the ear won't miss.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.
Structural neighbourhood: 3 → 13 → 63 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.

Entropy & irreversibility
Left alone, systems drift toward their most probable, most spread-out states — giving processes a direction in time that is hard to reverse.
Ask why a process only runs one way. Order can grow locally only by exporting more disorder elsewhere — and it always costs energy.
Trade-offs
When getting more of one thing means accepting less of another, because resources or constraints are limited.
Ask what you give up (the opportunity cost) to gain what you want.
