+Unlisted relative Sentry API endpoints used by sentry-cli
+
+- "/organizations/" (with pagination `?cursor=`)
+  - Where: `src/api/mod.rs` in `AuthenticatedApi::list_organizations`
+  - Note: Your list includes "/organizations/" but not explicitly the listing endpoint with pagination. Pagination query params are ignored per instructions; keeping here only to show callsite coverage.
+
+- "/projects/{org}/{project}/releases/{version}/files/{file_id}/?download=1"
+  - Where: `src/api/mod.rs` in `AuthenticatedApi::get_release_file`
+  - Status: NOT in provided list (download variant)
+
+- "/organizations/{org}/releases/{version}/files/{file_id}/?download=1"
+  - Where: `src/api/mod.rs` in `AuthenticatedApi::get_release_file`
+  - Status: NOT in provided list (download variant)
+
+- "/monitors/{monitor_slug}/checkins/"
+  - Where: Sent via the Envelopes API (DSN envelope endpoint). Tests mock this relative REST endpoint: `tests/integration/monitors.rs`
+  - Status: NOT in provided list. Although CLI sends monitor check-ins as envelopes to the DSN endpoint, the relative check-ins endpoint appears in tests.
+
+- "/projects/{org}/{project}/files/proguard-artifact-releases"
+  - Where: `src/api/mod.rs` in `AuthenticatedApi::associate_proguard_mappings`
+  - Status: In provided list
+
+- "/projects/{org}/{project}/files/dsyms/"
+  - Where: `src/api/mod.rs` in `RegionSpecificApi::upload_dif_archive`
+  - Status: In provided list
+
+- "/projects/{org}/{project}/releases/{release}/files/"
+  - Where: `src/api/mod.rs` in `RegionSpecificApi::upload_release_file`
+  - Status: In provided list
+
+No other relative endpoints beyond those already listed were found in `src/` (including releases, deploys, issues, events, artifacts, chunk upload, assemble endpoints, regions, repos, monitors list, projects list). JavaScript wrapper code does not add additional relative API endpoints.
