PYTHEIA 2.1.1 — WINDOWS EVALUATION DISTRIBUTION
Maintenance build: 26L33 — pandas coordinate-loading correction.
Initial release publication and verification history follows below.

Windows reference fitting and Az/El evaluation checks: complete.
Published v2.1.1 production signature: passed both compiled integrity verifiers.
Published v2.1.1 distribution ZIP: inventory, CRC, and archived-file bytes verified.
Website publication: completed 2026-10-24.
All 10 uploaded website files matched prepared sizes and SHA-256 hashes.
Visual layout: confirmed.
These results apply to published v2.1.1, not to a modified maintenance package.

Includes the isolated Python runtime and required dependencies.
The public package must contain no customer activation or private signing material.

COMPLETED 2.1.1 CHECKS
Bundled 120-star Az/El reference fit completed with exit code 0.
Displayed converged rigorous fit RMS: 2.5608 arcseconds.
Existing-model evaluation completed with exit code 0.
Evaluation with --external completed with exit code 0.
Both evaluation modes exported identical 120-row residual CSVs.
CSV-derived rigorous total RMS: 2.560785 arcseconds.
CSV-derived first-order total RMS: 4.153217 arcseconds.
Evaluation left the coefficient file unchanged.
Population SD removed 8 fitted-parameter degrees of freedom normally,
and 0 with --external.
All 5,422 protected files in the tested installation matched the manifest
after restoration of mismatched runtime files.

SCOPE
These evaluation acceptance checks cover the supplied Az/El example.
Historical scientific-suite and TCS validation are described in README.md
and CHANGELOG.md.

LICENSING
Supports signed v1 date-based and v2 UTC timestamp evaluation licenses.
Standard website evaluation: 30 UTC calendar days from issuance.
Validity starts at the signed start, not installation or first use.
Expiry is exclusive. Other periods may be agreed with Orionis.
Longer evaluation periods do not create commercial rights.

PANDAS CORRECTION — MAINTENANCE BUILD 26L33
Explicit .loc normalization corrects the identified compiled-loader warning trigger.
No warning suppression or bundled pandas modification was used.
All 50 protected-loader cases passed across both coordinate modes.
Bundled Az/El fitting and both evaluation modes passed through the worker
and Windows executable without the diagnostic; residual CSVs matched.
Full fitting/evaluation acceptance remains limited to the bundled Az/El example.
These maintenance results are separate from the historical initial-release checks.

Read README.md for operation, LICENSE.txt for evaluation terms,
and NOTICE.txt plus docs for third-party notices.
