CDIP v3.1 PERIMETER_AUX TCFQ-DTS v0.2-RC Specification (Sealable Candidate) Dynamical Trust Surface for Time-Critical Fault Quantification

PERIMETER_AUX/TCFQ-DTS (Dim-2) is a strictly observational, deterministic, hyperbolic- geometry sidecar that monitors semantic drift S(t) on the Poincaré ball and performs a continuous–discrete duality check against the discrete Ricci-flow sidecar (Dim-7). This v0.2-RC hardens the v0.1 draft by: (i) removing any ambiguity around Telomere/TEANT event charging (no event_register calls); (ii) freezing deterministic numerics, arcosh table generation and indexing; (iii) introducing a time-synchronization gate for duality checks; (iv) defining a tri-valued sign policy with deadzones; (v) enforcing non-operative budgeting (budget affects admissibility only, never value); and (vi) aligning leaf schema and reason-codes with the CDIP v3.1 sidecar audit discipline (NI-2, alerts-only).
