Configured Observation Planes as Typed Interfaces: Seam-Resolved Triadic Markov Kernels, Regime-Labeled Geometry, and an Earned Selection-Chirality Witness

Working Draft (v0.1). This record presents a constraint-first framework that begins from O₀ (“an obtaining observation occurs”) and develops a typed interface normal form COP_slice := (O, P, C) for describable obtaining observation. The core discipline is explicit level separation (candidate/admissible/obtaining; slice/sequence) and explicit identity discipline (schema/class/token; Instantiate/Quotient/Choose), with “should expect” interpreted by default as constraint-typical (no implicit probability measure over worlds). The work then supplies a witness stack (mathematical receipts) showing realizability of the constraints: a seam-resolved triadic Markov framework (Track U) with a state space and transition kernel, continuity discipline (Feller), and stationary behavior in labeled regimes; a geometry/interface discipline (Track G) governing what may be asserted in “GOOD vs GENERAL” windows; and a closure/fixed-point lane under explicit hypotheses. Additional addenda develop a selection kernel (Darwin-style transition specialization) and toy-regime witnesses for chirality lock-in under stated dynamics. Physics-facing content is included as compatibility certificates only (conservative posture): the text does not claim to derive GR or QM, nor to resolve quantum gravity, but instead states bounded interface constraints and compatibility checks (e.g., record-token/registration discipline and regime-labeled invariance requirements) consistent with the project’s claim ceilings. Contents of this record: PDF of the main working draft, plus a companion ZIP containing the full proof/receipt vault (Track U, Track G, Part Two checkpoint + appendices, interface maps, claim/assumption ledgers, and addenda), along with manifest and QC notes.
