Is there a Blender bug report, commit message or regression test about the Mesh Cache modifier's PC2 Time-mode fps handling (frame = ((time / fps) - start) / sampling) or its Factor-mode scaling?

Scoped negative result. In the sources searched on 2026-10-22 (path-filtered commit lists for six Mesh Cache files from 2013-01-21 to 2026-06-15, GitHub commit search, projects.blender.org issue and PR search, and the tests/ tree at main commit f0e5cc32) none addresses PC2 Time-mode fps handling or Factor-mode scaling. No commit message mentions fps for these files except a mechanical FPS-macro replacement (2025-08-07). No test file for the Mesh Cache modifier, PC2 or MDD was found. The nearest records are issue #41118 (PC2 sub-frames, resolved as an exporter bug in 2014, mentioning Frame Scale), #60824 (units list naming Mesh Cache frame_start) and #34607 (MDD interpolation). Curator qualifications: Search scope (path-filtered commit history of six Mesh Cache files 2013-2026, GitHub commit search, projects.blender.org issues/PRs, tests/ tree at f0e5cc32) is stated; no report or test addresses PC2 Time-mode fps handling. Absence within that scope only. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
