ACTINV v1.1.1 — release notes

ACTINV 1.1.1 is a data-catalog patch release with one solver hardening fix. Schemas, solver order, public
interfaces and physics are unchanged from 1.1.0. The embedded data catalog advances to v1.1.0 so that
actinv data fetch installs the tendl-2025-patched remediation derivative qualified in P25c (data-v1.1.0
release).

Upgrade the Python package with:

python -m pip install --upgrade actinv

Rust CLI users can install this exact patch with:

cargo install --locked --force actinv-cli --version 1.1.1

What changes

  • The embedded catalog becomes actinv-data-catalog-v1.1.0.json; installed data lives under
    actinv-data/v1.1.0/.
  • The new default bundle tendl-2025-patched-neutron installs the P25c-qualified patched 709-group neutron
    activation library — an Avila Labs remediation derivative of TENDL-2025 that zeroes exactly the 44 enumerated
    leaked leading ordinates across the 28 confirmed-signature files and is byte-identical to the official archive
    everywhere else. It is not an official TENDL release.
  • tendl-2025-patched-neutron-covariance adds the MF=33 covariance sidecar rebuilt against the patched artifact;
    the sidecar index cryptographically pins the patched library's SHA-256.
  • actinv new now emits catalog:tendl-2025-patched-neutron-709g references.
  • All v1.0.0 artifact IDs resolve to exactly the same bytes: the proton, deuteron, alpha and decay assets are
    unchanged, and the superseded tendl-2025-neutron bundles remain fetchable for byte-compatible reproduction of
    earlier work.
  • CRAM linear solves now apply bounded iterative refinement (Lu::solve_refined) with compensated residual
    evaluation; the run certificate's numerical_floor note no longer claims a total numerical-error bound. Results
    are unchanged on previously green cases; the fix removes a trace-inventory precision loss in shifted solves.

Qualification boundary

The patched corpus passed the frozen P25c construction, coverage, surgical-integrity, leak-clearance and
retrospective nonregression gates — retrospective evidence of internal consistency, not blind validation. The
shipped patched artifact holds 1,679 targets / 87,075 rows: the full-corpus strict build ledgered 1,172
source-file exclusions across all defect classes. Five dosimetry-critical targets (Ni-58, Nb-93, Ag-109, In-113,
Au-197) still fail closed under non-signature defect classes, and 16 of the 17 previously defect-bearing IRDFF-II
targets are absent. ACTINV and the data remain research-grade; docs/DATA_LIMITATIONS.md and
docs/QUALIFICATION.md still apply.
