Module packaging the eight-tick (octave) period forced in Recognition Science: a domain cost, a positive canonical threshold, and an inhabited EightTick_v3 certificate that the discrete recognition clock closes after 2^3 ticks. Anyone citing the T7 landmark in the forcing chain uses this assembly. The file is mostly definitions plus elementary nonnegativity/positivity lemmas that witness the certificate.

claimThe module defines a domain cost, a strictly positive canonical threshold, and a certificate that the RS recognition period is eight ticks ($2^3$), i.e. one octave of the discrete clock built from the fundamental tick $\tau_0$.

background

Recognition Science forces discrete time from the cost functional and self-similarity. Landmark T7 of the forcing chain (UnifiedForcingChain) is the eight-tick octave: the minimal closed recognition period is $2^3=8$ ticks. The Constants import supplies the RS-native time quantum $\tau_0=1$ tick. The Cost import supplies the $J$-cost infrastructure used to score recognition defects.

This v3 module sits in Foundation and introduces a domain-level cost (domainCost), compares values against a canonicalThreshold, and packages the result as EightTick_v3Cert (with an inhabited cert). Sibling lemmas record evaluation identity, nonnegativity of the domain cost, and positivity of the threshold.

proof idea

Definitional assembly, not a deep derivation proof. The module declares domainCost and proves elementary facts (pointwise evaluation, nonnegativity). It declares canonicalThreshold and proves positivity. Those pieces feed EightTick_v3Cert / cert, with cert_inhabited witnessing that the certificate type is occupied. No multi-step tactic chain at module scope: the argument is cost bounds plus threshold comparison packaged into a named eight-tick certificate.

why it matters in Recognition Science

Earns its place as the Foundation packaging of T7 (eight-tick octave, period $2^3$) in the RS forcing chain, between phi self-similarity (T6) and $D=3$ spatial dimensions (T8). It ties Constants ($\tau_0$) and Cost ($J$-cost) into a single certifiable eight-tick artifact. The current graph lists no downstream used_by edges, so in this mirror snapshot it is a leaf certificate module rather than an intermediate lemma. Downstream work on octave timing, ladder synchronization, or the step into T8 would cite the inhabited certificate.
