+## Crash Reporting and Diagnostics
+
+Official releases enable privacy-safe crash reporting by default for unexpected CLI failures. It
+does not collect usage analytics, command results, or original error data. Manage the persisted
+preference with:
+
+```bash
+putio telemetry disable
+putio telemetry status
+putio telemetry enable
+```
+
+The preference lives in the normal private CLI config and applies to interactive, CI, agent, and
+other non-interactive runs. `DO_NOT_TRACK` does not override it. Missing config keeps reporting
+enabled; unreadable or invalid config fails closed for that process.
+
+The `crashReporting` object in `describe` shows the effective enabled state or disabled reason,
+flush deadline, preference commands, and captured-field allowlist.
+
+At most one synthetic event is sent per process. It contains a random event ID and timestamp, one
+of three fixed failure categories, fixed runtime labels, and the package release. It never contains
+the original error, message, or stack; credentials; config or environment contents; command names
+or arguments; request or response data; URLs; paths or filenames; full payloads; untrusted server
+text; or user and device identifiers. Reporting does not write to stdout, replace local stderr,
+change exit or signal behavior, follow redirects, retry, or make network access a command
+requirement.
+
+See [Architecture](./docs/ARCHITECTURE.md#crash-reporting-policy) for the exact payload, process
+boundary, provider ownership, retention, and removal policy. Use the private contact in
+[Security](./SECURITY.md) for sensitive reports or deletion requests.

+## Crash-reporting policy
+
+### Decision
+
+External crash reporting is approved as a bounded, enabled-by-default diagnostic sent to the
+dedicated `putio/putio-cli` Sentry project. The project is US-hosted, uses the Node platform, and
+is owned by the Sentry `frontend` team. It is operational diagnostics, not product analytics.
+
+`putio telemetry disable` persists the only user preference as `telemetry_disabled: true` in the
+normal private CLI config. `putio telemetry enable` removes that field, and `putio telemetry status`
+reports the preference without authentication. Startup reads only that boolean before initializing
+Sentry. A missing config keeps the default enabled; an unreadable, invalid, or unexpected config
+fails closed and disables reporting. Released npm and standalone artifacts receive a validated DSN
+at build time. Source and pull-request builds omit it and fail closed without initializing Sentry or
+installing crash handlers. The same enabled default applies in CI, agents, and other non-interactive
+execution when the artifact contains release configuration.
+`DO_NOT_TRACK` is not a separate control; those environments use the same persisted
+`putio telemetry disable` preference and config-path precedence. Online and offline command
+behavior is otherwise identical.
+
+### Failure boundary
+
+Expected typed Effect, CLI, SDK, and API failures remain ordinary command errors. Unexpected
+Effect defects, uncaught exceptions, and unhandled rejections are eligible for one synthetic event
+per process when reporting is enabled. The local error is rendered through stderr first for Effect defects.
+Global handlers remove themselves after the first fatal event, perform a bounded flush, and replay
+the original uncaught exception or rejection to Node. Stdout remains reserved for command results,
+ordinary failures keep exit status 1, and interrupt-only causes continue to the Node runtime so
+their signal semantics are preserved.
+
+Capture and flush failures are discarded. The flush deadline is 250 milliseconds, with no retry.
+Reporting never replaces the original local error or delays termination beyond that bound.
+
+### Data and operations
+
+Events are built from an allowlist and then projected through the same allowlist immediately before
+transport. The transport accepts only the one expected event ID and failure category, drops
+SDK-internal or malformed envelopes, and rebuilds the serialized envelope rather than forwarding
+SDK output. The transmitted event contains a random event ID and timestamp, fixed message and
+component/platform labels, one of three fixed failure-category tags, the fixed `production`
+environment, fixed fatal level, logger, and message/category fingerprint, and package release
+`@putdotio/cli@<version>`. The Sentry envelope also carries the public DSN routing metadata required
+by the provider.
+
+The original error, message, and stack are never passed to Sentry. Events also exclude tokens,
+profiles, environment variables, configuration values, command names and arguments, API bodies,
+URLs, paths, filenames, full payloads, untrusted server text, breadcrumbs, device identifiers,
+and user identifiers. Default Sentry integrations, client reports, logs, tracing, server-name
+detection, PII capture, breadcrumbs, and stack attachment are disabled. Because no stack is sent,
+this integration has no source-map upload.
+
+The release workflow reads `PUTIO_CLI_SENTRY_DSN` from the protected `release` GitHub Environment,
+validates it as an HTTPS Sentry DSN, and injects it into npm and standalone builds. Release builds
+fail when that value is missing or invalid. The DSN remains a public project-routing key embedded in
+the resulting artifacts; Sentry auth and admin tokens remain outside the repository and release
+artifacts. The `frontend` team owns the project and manual support path. Events inherit the put.io
+Sentry organization's current retention contract and are used only for debugging, not product
+analysis. Removal requests go through the private contact in SECURITY.md; `putio telemetry disable`
+prevents future events but does not itself delete an already delivered event.
+
+Local diagnosis should use the CLI version, installation method, operating-system name,
+interactive/CI/non-interactive context, command name and output mode, and the smallest useful
+sanitized stderr excerpt. It must not include command arguments or any of the excluded data above.
+Sensitive reports and deletion requests go to the private security contact.
+

 Release GitHub writes use `putio-releaser` for version sync commits, `v*` tags, GitHub Releases, binary asset uploads, and Homebrew tap formula commits. The app installation grants Contents read and write access to `putio-cli` and `homebrew-tap`; the Homebrew job mints an installation token scoped to those two repositories.
 
 The npm package uses Trusted Publishing from GitHub Actions. On npm, configure owner `putdotio`, repository `putio-cli`, workflow `ci.yml`, and Environment named `release` for the package.
