Zpe Python Packages

zpe-image

Bounded sparse-stroke codec — 5.75× mean byte reduction on 5 accepted figures, 100% rejection on 7 natural-image probes. Glyph, maze, skeleton, flow-graph. Not a natural-image codec. v0.1.0 on PyPI.

zpe-video

Perception receipts for AI video pipelines. Cross-writer bit-exact under default settings (SHA-256 stable across writers in any language). Zero runtime dependencies; pure stdlib core. ~1.1 KB per video; per-frame CRC32 + schema + versioning. Useful now, improving continuously.

zpe-diagram

ZPE-Diagram v0.1.0 — bounded structural-and-style diagram codec. Six declared synthetic SVGs round-trip exactly across geometry, color/stroke, and draw order. Out-of-scope inputs (fill, dash, palette escape) rejected at encode time. Not a compression codec.

zpe-music

ZPE-Music V0.0: DETERMINISTIC SYMBOLIC SCORE CODEC: MusicXML Roundtrip | Note-Local Expression Refinement | Attack | Release | Dynamics

zpe-smell

ZPE-Smell V0.0: Surrogate-receptor odor codec on a fixed 35-episode benchmark | Spearman 0.9996 | 0% mixture collision | Empirical olfactory perception out of scope

zpe-taste

Evidenced-negative taste object — failed the geometry-bearing fit gate (metric_fit 0.207 vs 0.6 threshold). The committed negative reference is preserved as the lab record. No positive taste codec is claimed.

zpe-touch

ZPE-Touch V0.0: DETERMINISTIC TOUCH STREAM CODEC: Contact Geometry | Thermal | Vibrotactile | Proprioceptive Branch Isolation | Rust Core

zpe-mental

Tunnel, spiral, lattice, cobweb — byte-exact codec on the bounded four-form corpus. Rust-native fast path with a Python reference. Not a cognition or clinical claim.
