pub const RESEARCH_DOCUMENTED_BUCKETS: &[&str];Expand description
Codenamed forward-compat buckets observed in the live endpoint
during research captures (see docs/research/claude-data-files.md
§Raw data, 2026-04-18 capture). These are unrecognized by
UsageApiResponse’s strict struct fields but Anthropic ships
them on every response — gating the doctor’s
“endpoint.shape_current” WARN on this list keeps the report quiet
on healthy accounts while preserving the WARN for new unknown
keys (the actual signal a maintainer wants).
Refresh whenever the research doc captures a new live response.
