All three projects use release `mobile-dev@`. +TraceSift cards use the `tracesift` surface. `tracesift.operation.duration` measures local service readiness as part of analysis, profile upload and analysis, and handoff generation in milliseconds; `tracesift.operation.samples` records the bounded operation and success/failure outcome. `ui.tracesift.process` measures result validation, `ui.tracesift.handoff` measures the app-to-server handoff round trip, and `ui.tracesift.message_ack` ends when the host acknowledges the investigation message. A card-count gauge and bounded counters cover Investigate actions, handoff failures, composer unavailability, send failures, and unconfirmed delivery. Readiness, shared interaction, visibility, and cleanup measurements use the existing UI aggregation. Profile paths and contents, filenames, card text, analysis/card identifiers, handoffs, service URLs, process identifiers, tokens, and TraceSift diagnostics are never added to telemetry. Expected setup, validation, expiry, cancellation, and version outcomes use existing expected-error classification; unexpected transport and malformed-response failures retain handled server/UI error coverage.

For a public release, run `npm run build:release` followed by `npm run package:release`. Packaging rejects a build from the other environment. The package stores its environment in `dist/telemetry-environment.json`; Node telemetry, native helpers and the served UI use that setting. Live reload does not determine the environment.

These measurements describe plugin and local-service work, not the profiled app's performance. The environments are `development` and `release`. `npm run build` and `npm run package` default to `development`, including local installed packages. For a public release, run `npm run build:release` followed by `npm run package:release`. Packaging rejects a build from the other environment. The package stores its environment in `dist/telemetry-environment.json`; Node telemetry, native helpers and the served UI use that setting. Live reload does not determine the environment.
