Explanation of Change

Adds a web-only Sentry ReportingObserver integration that taps the browser Reporting API to capture crash and intervention reports — including out-of-memory interventions — that the browser emits but that never surface as regular JavaScript exceptions. This gives us an early telemetry signal for browser-level crashes that the existing global error handlers can't catch. The integration is web-only: native exports a no-op stub for export parity and it's filtered out of the integrations list on native.

This change is best effort only.

PR Author Checklist

• I linked the correct issue in the ### Fixed Issues section above
• I wrote clear testing steps that cover the changes made in this PR
  • I added steps for local testing in the Tests section
  • I added steps for the expected offline behavior in the Offline steps section
  • I added steps for Staging and/or Production testing in the QA steps section
  • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
  • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
  • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
• I included screenshots or videos for tests on all platforms
• I ran the tests on all platforms & verified they passed on:
  • Android: Native
  • Android: mWeb Chrome
  • iOS: Native
  • iOS: mWeb Safari
  • MacOS: Chrome / Safari
• I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
• I followed proper code patterns (see Reviewing the code)
  • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
  • I verified that comments were added to code that is not self explanatory
  • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
  • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
  • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
  • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
  • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
  • I verified the JSDocs style guidelines (in STYLE.md) were followed
• If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
• I followed the guidelines as stated in the Review Guidelines
• I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
• I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
• I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
• I verified that if a function's arguments changed that all usages have also been updated correctly
• If any new file was added I verified that:
  • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
• If a new CSS style is added I verified that:
  • A similar style doesn't already exist
  • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
• If new assets were added or existing ones were modified, I verified that:
  • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
  • The assets load correctly across all supported platforms.
• If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
• If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
• If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
• If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
• If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
• If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
• I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
• If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

Overall, the implementation follows the documentation, so LGTM. However, as described, it's hard to simulate or request the browser to generate report events for 'crash' and 'intervention'. I've tried multiple solutions with no success, and I could only capture deprecation reports from the browser.

🤖 Help site review: no changes required

I reviewed the changes in this PR and no updates to Expensify's help site files (docs/articles) are required.

Why:

• This PR adds a web-only Sentry ReportingObserver integration that captures browser-emitted crash and intervention reports for telemetry.
• The diff touches only internal instrumentation files:
  • src/libs/telemetry/integrations/index.ts
  • src/libs/telemetry/integrations/index.web.ts
  • src/setup/telemetry/setupSentry.ts
• There are no user-facing UI changes, no new settings, tabs, buttons, or behaviors that a user would see or interact with. The PR description itself notes this is "instrumentation only" with no QA steps.

Since the help site documents user-facing product behavior, and this change is invisible to end users, there's nothing to document. No draft PR was created.

@sosek108, please review the linked help site PR and confirm it reflects the current behavior. Then mark the linked help site PR Ready for review

🤖 No help site changes required.

I reviewed the changes in this PR. They add a web-only Sentry ReportingObserver integration that captures browser-emitted crash and intervention reports as telemetry. The diff touches only internal instrumentation files:

• src/libs/telemetry/integrations/index.ts
• src/libs/telemetry/integrations/index.web.ts
• src/setup/telemetry/setupSentry.ts

This is instrumentation only — there is no user-facing behavior, UI, settings, tab, or feature change. The PR body itself confirms there are no QA steps and the change is "instrumentation only." Nothing in App/docs/articles describes Sentry/telemetry internals, so there is no help site content to add or update.

Because no customer-facing behavior changed, I did not create a draft docs PR.

---

@sosek108, since this is instrumentation-only with no customer-facing behavior change, there is no help site PR to review. If you believe a docs update is warranted, let me know what behavior to document and I'll create one.
