Conversation
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>

Add new namespaced attributes for mobile app performance monitoring and deprecate their old counterparts.
New attributes:
app.start.value— app start duration in millisecondsapp.start.type— app start type (cold/warm)app.ttid.value— time to initial display in millisecondsapp.ttfd.value— time to full display in millisecondsapp.frames.total.count— total frames rendered during span lifetimeapp.frames.slow.count— slow frames rendered during span lifetimeapp.frames.frozen.count— frozen frames rendered during span lifetimeapp.frames.delay.value— sum of delayed frame durations in secondsDeprecated (backfill status, with aliases on both sides):
app_start_type→app.start.typeframes.total→app.frames.total.countframes.slow→app.frames.slow.countframes.frozen→app.frames.frozen.countframes.delay→app.frames.delay.valueAll new attributes include mobile SDK entries and
pii: maybeper CONTRIBUTING.md policy. Deprecations follow the alias + backfill pattern documented in CONTRIBUTING.md.
