Binary Reachability under Observation-Point Fixing (v0.8.1)

This record publishes v0.8.1 as a public implementation log and audit-ready release of Binary Reachability under Observation-Point Fixing. It is not presented as the final consolidated theory version. Its role is to lock the current implementation structure, reproducibility logic, worked example, and failure-specification layer prior to later v1.0 consolidation. The release package contains:- main manuscript (DOCX + PDF)- SI-0 to SI-5 (DOCX + PDF)- Main/SI correspondence map- INSTALL_ME- RELEASE_TAG Package positioning:- public implementation log- audit-ready release- non-final, pre-v1.0 consolidation- no-overclaim posture Non-claim boundary:This release does not claim a proof of the Riemann Hypothesis, a proof of Navier-Stokes regularity, a universal threshold law, a replacement of standard quantum mechanics or fluid dynamics, a final universal law of nature, or a complete reduction of disparate domains to one formula. It does claim:- an implementation-ready theory of fixed-setting structural classification- an audit-ready classification layer under observation-point fixing- explicit score, threshold, computational, and failure-mode structures Integrity:- SHA256 manifest provided- detached PGP signatures and public key may be provided outside the ZIP package
