+## Local Info Egress Status
+
+This fork has removed several local system and project metadata egress paths that existed in the recovered upstream code.
+
+Removed in this repository:
+
+- Model-request context injection of working directory, git status/history, `CLAUDE.md`, current date, platform, shell, and OS version.
+- Feedback upload and transcript-share upload paths.
+- Remote Control / Bridge registration fields that sent machine name, git branch, and git repository URL, plus git source/outcome data in bridge session creation.
+- Trusted-device enrollment and trusted-device token header emission for bridge requests.
+- `/insights` automatic S3 upload; reports now stay local via `file://` paths only.
+
+Still present:
+
+- Normal Claude API requests are still part of product functionality; this fork only removes extra local metadata injection, not core model/network access.
+- Datadog and Anthropic 1P analytics codepaths still exist and can emit environment/process metadata unless disabled by runtime privacy settings.
+- GrowthBook remote evaluation still exists and still prepares remote-eval user attributes.
+- Optional OpenTelemetry export still exists behind telemetry configuration flags.
