Add app.start.cold.value, app.start.warm.value, app.ttid.value, and app.ttfd.value attributes for tracking cold/warm app start durations and time to initial/full display metrics. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Per CONTRIBUTING.md policy, pii MUST be maybe or true unless scrubbing would break product features. Duration values don't need exemption. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…old ones Replace app.start.cold.value/app.start.warm.value with app.start.value and app.start.type. Add app.frames.total.count, app.frames.slow.count, app.frames.frozen.count, and app.frames.delay.value under the app namespace. Deprecate frames.* and app_start_type with backfill status per CONTRIBUTING.md policy. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

There was a problem hiding this comment.
Cursor Bugbot has reviewed your changes and found 1 potential issue.
Bugbot Autofix prepared a fix for the issue found in the latest run.
- ✅ Fixed: Frames delay value typed as integer, not double
- Changed the type from "integer" to "double" in the JSON model and regenerated the TypeScript and Python files to preserve fractional precision for frame delay durations.

Pull request overview
Adds new namespaced mobile performance attributes under app.* (app start, initial/full display, and frames metrics) and deprecates legacy counterparts (app_start_type, frames.*) using the alias + backfill deprecation pattern.
Changes:
- Introduce new
app.start.*,app.tt{ i d| f d }.value, andapp.frames.*attributes with SDK coverage metadata. - Deprecate legacy attributes (
app_start_type,frames.total|slow|frozen|delay) and add symmetric aliases to the replacements. - Regenerate language bindings (Python + TypeScript) and the generated deprecated-attributes index.

…display Add time_to_initial_display and time_to_full_display as deprecated attributes with backfill status, pointing to app.ttid.value and app.ttfd.value respectively. Adds aliases on both sides and SDK usages. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Change app.frames.delay.value type from integer to double since frame delays are fractional seconds - Fix frames.* deprecation reasons to say "Old frames.* attribute" instead of "Old namespace-less attribute" - Improve app.start.type brief to mention cold/warm examples Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Had two optional suggestions/questions but otherwise LGTM!
… keys Rename all new attributes to app.vitals.* namespace. Replace app.start.value + app.start.type with app.vitals.start.cold.value and app.vitals.start.warm.value. Add app.vitals.start.type deprecating app_start_type. Improve deprecation reasons across all deprecated attributes. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
