bit.analyze: Universal Structural Stream and Temporal Multimodal Associations — v0.2.0-rc1

Abstract

bit.analyze v0.2.0-rc1 — Release Candidate bit.analyze v0.2.0-rc1 is a pre-release candidate that extends the v0.1.0 structural-memory baseline with two experimentally validated layers: a bounded universal structural byte stream and a pre-semantic temporal multimodal association model. The release remains research software. It does not claim semantic understanding, causal inference, cognition, or general-purpose compression superiority. Main additions modality-agnostic StructuralEvent / StructuralStream processing; rolling and bounded structural fingerprints for incremental streams; deterministic gates for recycling, renormalization, memory bounds, out-of-order rejection and fragmentation equivalence; temporal structural baselines and recurrence/change experiments; immutable RealitySlice records with timestamps, modalities and provenance; temporal association based on proximity, repetition, direction and forgetting; directional coverage and reliability metrics; adversarial structural-closure ranking for correlated distractors. Pre-release validation The candidate was validated in GitHub Actions on the consolidated code path. Linux build/test: pass Windows build/test: pass independent Canterbury corpus job: pass release benchmark job: pass 100,000-slice hidden-structure gate: pass hidden structural-pair recovery: 6/6 100,000-slice adversarial gate: pass adversarial expected relations: 9/9 adversarial evidence margin: 3.133x required adversarial margin: 2x The 2x acceptance threshold was retained; it was not relaxed to make the candidate pass. Important interpretation boundary The temporal multimodal experiment identifies recurring structural relations across time and modalities. Directional reliability measures how consistently an observed temporal relation recurs. Structural closure rewards links supported by strong shared-neighbor relations. None of those quantities is a causal probability or semantic interpretation. Compatibility Snapshot formats and newly introduced experimental structures are not yet declared a stable public compatibility contract. This is one reason the version is published as rc1 rather than a final v0.2.0. License Distributed under the Resolutive Research and Non-Commercial License (RRNCL) v1.0.

A distinct archival identifier for v0.2.0-rc1 should be recorded after the new release is deposited.
