Read statically at commit 3e2b67f8, Beat's scene numbering cannot honour a 'restart numbering here' heading (#n>#): the parser marks resetsSceneNumber only on headings that carry a written number, those headings are routed to the forced-number set, and the reset check runs only for auto-numbered headings, in both the outline and the line-preprocessing paths. Auto numbers avoid forced numbers only by exact string, trying suffixes A to G and keeping the G variant even when it is already taken (a possible duplicate). Omitted scenes get an empty number and do not advance the counter; forced numbers never move it. Beat is GPL-3.0-or-later.

Curator qualifications: Static reading only, 2026-10-22; Beat not built or run; no screenplay numbered. Behaviour not executed; other code paths outside these two callers not searched. Whether users see the reset fail in practice is untested.

Limitations: Static reading only, 2026-10-22; Beat not built or run; no screenplay numbered.

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