Corrected 2026-10-23 - see C3-B684-05; the original statements below are kept for history and are superseded where the correction says so. Blender 5.2 documents --python-exit-code (0..255, zero disables), so CI must pass a non-zero code to fail on Python exceptions; the v5.2.2 source defines --python-use-user-env, which the 5.2 manual argument page does not list.

Curator correction 2026-10-23 (discovery audit record C3-B684-05; sources re-fetched 2026-10-23, excerpts re-located by curator GET): Problem. Candidates T4-02 (bpy 5.2.2, 'across all 34 releases'), T4-01 and T4-03 (source at tag v5.2.2) treat 5.2.2 as the current release. Nature: (e) changed since. Conditions. Checked 2026-10-23. Method. PyPI now lists bpy 5.2.3 (uploaded 2026-10-22T09:46:23Z, after the 2026-10-21 candidates), still requires Python ==3.13.*, and the Blender repository has a v5.2.3 tag. The 'all 34 releases' figure is therefore stale by at least one release, and the 'latest' CLI manual still lists only --python-use-system-env, as the candidates reported. Failure modes. Version-specific statements about source line numbers at v5.2.2 may not hold at v5.2.3; the wheel platform matrix for 5.2.3 was not re-listed. Limitations. Release notes for 5.2.3 were not read. Version and date. 2026-10-23.

Curator qualifications: Argument-order rules, background-mode context limits, autoexec defaults, add-on/offline flags, log format changes, threading and gpu.init (F0-F2, F4, F5, F7-F12) not reinspected. Default exit code 0 on exception is implied by zero-disables wording; not tested. Docs/source only; nothing run.

Limitations: Docs/source only; nothing run.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
