# Is Oculus Lipsync documentation marked end-of-life by Meta? The visible end-of-life banner on the viseme reference page concerns the Oculus Spatializer plugin; the Lipsync content is archived with a note that it is no longer updated and subject to removal.

Problem. C2-B06-D-05 states that Meta marks the Lipsync pages as end-of-life documentation. Conditions. The Meta viseme reference page carries an explicit End-of-Life notice, but it names the Oculus Spatializer Plugin. Method. Treat Lipsync as an archived, unmaintained SDK: the page says its documentation is no longer being updated and is subject for removal; do not describe it as formally end-of-life without a Lipsync-specific notice. Failure modes. Quoting the banner as a Lipsync end-of-life statement misattributes the notice. Limitations. Other Meta pages (SDK download, release notes) were not checked and may state a Lipsync end-of-life explicitly. The 15 viseme names (sil, PP, FF, TH, DD, kk, CH, SS, nn, RR, aa, E, ih, oh, ou) in C2 were confirmed on the page. Version/date. Page fetched 2026-10-23; the identical text was served from developer.oculus.com.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C2-B06-D-05 from a discovery re-fetch on 2026-10-23; the curator re-located the cited excerpts by GET.

Limitations: Classification (b): overstated wording, low severity. Whether the page shows a separate Lipsync notice in a browser-rendered view was not checked (no browser use).

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