<observations> Date: Aug 4, 2026 * 🟡 (21:10) Agent read sentry/utils/geo.py (64 lines) — `geo_by_addr` is no-op by default (returns None), gets replaced by `_init_geoip` which opens `settings.GEOIP_PATH_MMDB` via maxminddb and returns `{country_code, region, city, latitude, longitude}`. Also has `_init_geoip_rust()` setting module-level `rust_geoip: None | GeoIpLookup` via `sentry_relay.processing.GeoIpLookup.from_path`. Both init functions called if `settings.GEOIP_PATH_MMDB` is truthy * 🟡 (21:10) Agent traced twemproxy pattern across settings: all twemproxy hosts use trailing-dot FQDN (cluster.local.:11211) in cellsilo.py:1133-1146 and controlsilo.py:254 — consistent with new orbital default. KAFKA_BOOTSTRAP_SERVERS in singletenant.py:393 does NOT use trailing dot (cluster.local:9092) — mixed pattern in codebase * 🟡 (21:10) Agent reasoning on dispatch_uid semantics: with `weak=False` + `dispatch_uid`, Django keeps the FIRST registered receiver after reload — old `_notify_orbital` remains connected, new noop is NOT swapped in. Test only verifies direct-call path to `orbital.notify_orbital`, not signal-fired path. In production this is fine because no reloads occur; module-level globals like `udp_socket` and `geo_by_addr` are looked up at call time, so old function still sees mocked values * 🟡 (21:11) Agent read getsentry/testutils/cases.py:124-149 — `GetsentryTestCase(TestCase)` with `databases = "__all__"` for full DB flushing. Helper `_run_feature_check(handler, org)` and `create_detector_with_snuba_subscription(*, is_error_type=True, detection_type=None, status=None)` returning Detector wired to SnubaQuery via DataSource * 🟡 (21:11) Agent got jj error (not a jj repo, this is a git repo) and partial git log of branch fix/orbital-volume-metrics-ip-dns. Commits on branch: 29dde78bca `fix(orbital): add dispatch_uid to event_accepted.connect`, 86e8df26c4 `test(orbital): use empty string instead of None for unset`, ae1ed477fe `test(orbital): exercise noop and startup paths via reimport`, d5a1d30bab `fix(orbital): drop unused type: ignore on sendto`, 1140515902 `fix(orbital): noop when socket unset, FQDN default DNS`, 6822013f33 `fix(orbital): restore notify metrics, IP fallback, and Service DNS`, 673bf52f69 getsentry/sentry@f5465b21f3b2d263f8809223171185c1763901d5, 513daac7a2 getsentry/sentry@c8e25a53acd5b1707cf1ed427bc888b6e7293dca, 4d8cf1a2f6 getsentry/sentry@996740e2151646c68fafb5cdd4900c5eb9644ca1, plus 2ff449d0d8 `ref(replays): add start/end date range to delete_replays and per-day manifests for Ramp (#21331)` * 🟡 (21:11) Branch is fix/orbital-volume-metrics-ip-dns; tip commit 29dde78bca5f95b3bf0acb6fe5bc6743d642a7a6 * 🟡 (21:11) Agent got diff for branch — full PR diff (cellsilo.py + orbital.py + test_orbital.py) against revision `origin/main...HEAD` which failed but produced useful output. Key changes: - cellsilo.py:2293-2303: US cell default changed from `10.2.0.43:5556` (stale Internal LB IP since 2019) to `orbital-udp.default.svc.cluster.local.:5556` (in-cluster Service DNS).
