Summary

0.7.0 ships ONE engine line and a substantially hardened miner.

  • Pow alignment (real semantics): pow at a -inf base with a finite non-integer exponent is NaN across the constant folder, the operator realizations, and the interval engine; magnitude-step cells at infinite exponents unchanged.
  • BREAKING — faithful dev_7-3 reproduction line removed: the fold parameter, quirk-preserving conversion variants, and frozen parity fixtures are gone. To reproduce the legacy behavior byte-for-byte, install simplipy<=0.6.0.
  • LLM-proposal channel: find_rules(..., proposals=...) certifies external candidate rules through the identical certification chain and merges the survivors, making a mined-plus-proposed ruleset reproducible from one config and one command.
  • Special-point certification phase: witness constants snap to their shipped integer/half-integer form before the domain-preservation gate; every accepted pair is checked at a battery of symbolic contract points per variable and a battery of special source-constant values; deployed-vs-contract diverging rows are re-judged at three fixed precision rungs. Closes three certification gaps where a rule could pass random evaluation matrices yet be unsound at points deployed expressions actually reach.
  • engine_id now reports the package version; CLI find-rules -o accepts a bare filename.

Test plan

  • cargo test (69 passed), cargo fmt --check, cargo clippy (no new warnings)
  • full pytest tests on the built wheel (272 passed), including the new TestSpecialPointCertification battery
  • miner output determinism: repeated full mines byte-identical (including an intentionally CPU-contended pass)

…ean engine line)

pow at a -inf base with finite non-integer exponent is NaN (real semantics) across
the constant folder, operator realizations, and interval engine; magnitude-step
cells at infinite exponents unchanged. BREAKING: the dev_7-3 reproduction line is
removed (fold selector, legacy conversion variants, frozen 0.2.15 fixtures, port
anchors) -- reproduce v23.0-era behavior with simplipy<=0.6.0. Parity fixtures
re-baselined to the aligned line; engine_id reports the package version.
Gates: cargo 63/63 warning-free; wheel-venv pytest 263/263; blast radius 0/2000;
mkdocs strict clean. Known: dev_7-3 asset rule exp(u/0)->pow(-inf,u) is C99-era
value-certified and inconsistent under aligned semantics (2/10k; narrow test skip;
asset deliberately unchanged -- historical ruleset, superseded by the next mine).

… battery, source-constant sweep

Certification gains a judge-grade special-point phase: fitted witnesses snap
to their shipped integer/half-integer form before the domain-preservation
gate, every accepted pair is checked at a battery of symbolic contract points
per variable, and single-constant sources sweep a battery of special constant
values. Deployed-vs-contract diverging rows are re-judged at three fixed
precision rungs with coordinates rendered per precision, keeping stable
limit completions while rejecting precision-dependent seams fail-closed.
