CSV Bridge 0.1.1 — Verification scope, 11 October 2026

Previous automated suite: 29 passed, 2 Windows symlink tests skipped because
the required privilege was unavailable, 0 failures. Seven frozen CLI scenarios
passed with Python/Tcl environment variables removed.

Native GUI: analysis, selected decimal conversion, new XLSX export and Excel
opening observed. Leading zeros and a twenty-digit identifier remained intact.
Independent XLSX reading checked text cell types, selected decimals and multiline
values. This is technical verification, not evidence of customer demand.

Thirteen native negative/error cases passed: outputs before analysis, invalid
row shape, missing file, malformed quotes, export after failed analysis, save
cancellation, changed delimiter, changed input path, invalid Portuguese decimal,
formula-like CSV with prefixes disabled, and an existing output filename.
No source or existing output was overwritten in these checks.

Permission-error handling was exercised through the GUI callback with a
synthetic PermissionError. The error was reported without changing the previous
output or showing export success. This was not a real native permission-dialog
test. Filesystem permissions were not modified to manufacture such a test.

Not yet verified: independent clean Windows installation, a real customer's
workflow, actual native denied-permission save path, or every Windows/security
configuration. Executable is unsigned. No measured performance or time-saving
claim. Version 0.1.1 remains a free evaluation.
