📝 WalkthroughWalkthroughTelemetry reporting now uses a machine identity derived from a valid hardware address or a persisted UUID fallback. Reporting also requires a production runtime and a persistent identity. Event tags and common properties include the machine identity and its source. ChangesTelemetry machine identity

Merge Risk: 🟡 Moderate · up to Some machines may share a telemetry identity, and telemetry can send the new identifier before the revised notice appears. Resolve these risks before merging. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to A machine-linked identifier enables broader correlation than the previous installation identifier. Reporting can also proceed before the revised notice is displayed, or after an opt-out when a report was already queued. Existing opt-out and reporting controls limit, but do not eliminate, that exposure. Retained concerns

- Around line 121-124: Update formatMacAddress to reject addresses that are all
zero at any length and the known eight-byte tunnel-adapter sentinel, while
continuing to accept other valid lengths such as unique EUI-64 addresses. Add a
regression test through fromHardwareAddresses that puts the sentinel before
VALID_MAC and verifies the identity uses VALID_MAC_HASH.
In
`@bundles/com.espressif.idf.core/src/com/espressif/idf/core/telemetry/TelemetryService.java`:
- Around line 261-265: Update the English and Chinese telemetry documentation
and preference text to disclose that the persistent pseudonymous identifier may
be derived from a valid MAC address or a persisted random UUID; remove claims
that telemetry is anonymous or the identifier is not derived from machine
attributes. Update the notice-state version or reset `telemetryNoticeShown` so
affected existing installations see the revised disclosure.

- Line 109: Update TelemetryStartup.earlyStartup() so reportSessionStart() is
deferred when TelemetryNotice.showIfNeeded() queues the revised notice, and
invoke it from the notice callback after the notice opens; preserve the existing
startup reporting path when no notice is pending.
