The WebXR Device API at /TR/webxr/ is a W3C Candidate Recommendation Draft dated 9 June 2026 (not a Recommendation) and defines five reference-space types (viewer, local, local-floor, bounded-floor, unbounded) with spatial-tracking consent requirements; OpenXR's spaces chapter (release-1.1.65) uses VIEW, LOCAL, LOCAL_FLOOR and STAGE tokens. Names overlap, but no normative mapping between the two sets is stated in the texts read.

Curator qualifications: Local-floor fingerprint rounding (1 cm suggested; producer E2) not re-read verbatim. Axis/handedness conventions not compared; any one-to-one mapping (e.g. bounded-floor ~ STAGE) is synthesis. Specification text only.

Limitations: Draft standard; live TR URL.

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