Establishes that the breath cycle constant equals 1024 and is strictly positive over the reals. Memory thermodynamics researchers cite it when bounding decay rates of the form base_decay_rate times memory_cost divided by breath_cycle. The argument is a direct term-mode reduction that unfolds the constant definition and invokes norm_num.

claimThe breath cycle period $B$ satisfies $0 < B$ in the reals, where $B := 1024$.

background

The MemoryLedger module treats memory as a thermodynamic system in which retention competes with free-energy decay under Recognition Science rules. breath_cycle supplies the fixed natural number 1024 that appears in decay-rate expressions such as base_decay_rate * memory_cost / breath_cycle. Cost is the abbreviation Quantity CostUnit drawn from RSNative.Core and used to measure nonnegative J-costs of memory traces.

proof idea

Unfolds the definition of breath_cycle to expose the literal 1024, then applies norm_num to discharge the inequality 0 < 1024. No external lemmas are invoked; the proof is a pure computational check.

why it matters in Recognition Science

Supplies the positivity needed by five downstream theorems: emotional_forgets_slower, emotional_reduces_cost, forgetting_decreases, low_temp_bistable, and memory_cost_nonneg. These results establish monotonicity of forgetting, emotional cost reduction, and low-temperature bistability. It closes a required positivity gap inside the fully-proven thermodynamic memory chain and aligns with the eight-tick octave scaling of the Recognition framework.
