0.2.0 - 2026-07-22

The verified wheel and source archive are published on
PyPI. A clean Python 3.12
installation passed the packaged end-to-end consumer example.

Replace the legacy Jiuzhang state reconstruction with the published
paired-source Q7 construction and the exact real xxpp threshold-torontonian
matrix. The two v0.1 frontier JSON files remain historical artifacts and are
rejected by the current figure tooling.

A fail-closed Jiuzhang confirmatory-v2 workflow covering exposure-ledger
audit, outcome-blind design, immutable public registration and beacon-derived
selection, content-addressed evaluation, refusal recovery,
reconstruction/calibration uncertainty, joint normalizer replicates,
absolute predictive checks, simultaneous coherence-grid inference, and
hash-verified release bundles.
Canonical registration, design, and exposure templates plus focused contract
and regression tests for the workflow and exact xxpp construction.

Harden certified recursive-torontonian bounds with directed downward
subtraction, sound double-double magnitude bounds, and explicit
double-double-to-FP64 collapse residual accounting, plus a dedicated
enclosure gate.

This release provides code, templates, and validation contracts. It contains
no completed v2 registration or new scientific outcome; external calibration,
public timestamp/beacon evidence, and acquisition inputs remain required.
