@@ -170,12 +170,7 @@ Incremental policy:
 - For Xcode project regeneration, use `make xcgen` or `./apps/ios/scripts/regenerate-project.sh`. Do not run `xcodegen generate --spec project.yml --project Litter.xcodeproj` from inside `apps/ios`; that produces a nested `apps/ios/Litter.xcodeproj/Litter.xcodeproj`.
 - For Android emulator debugging, build with `make android-emulator-fast`, install with `adb -e install -r apps/android/app/build/outputs/apk/debug/app-debug.apk`, then launch with `adb -e shell am start -n com.sigkitten.litter.android/com.litter.android.MainActivity`.
 - Keep both runtimes available when validating shared Rust changes: boot a simulator with `xcrun simctl boot <device>` or through Simulator.app, and verify an emulator is visible with `adb devices -l`.
-- Start the collector with `cargo run --manifest-path shared/rust-bridge/Cargo.toml -p mobile-log-collector -- serve --bind 0.0.0.0:8585 --data-dir /tmp/mobile-log-collector-e2e`.
-- Query stored logs with either raw HTTP or the CLI: `curl 'http://127.0.0.1:8585/v1/query?limit=20'` or `cargo run --manifest-path shared/rust-bridge/Cargo.toml -p mobile-log-collector -- query --base-url http://127.0.0.1:8585 --device-id <id> --pretty`.
-- iOS simulator log config lives under the app container at `.../Library/Application Support/codex/log-spool/config.json`; use `xcrun simctl get_app_container booted com.sigkitten.litter data` to find the current container, then write the config there.
-- Android log config lives at `files/codex-home/log-spool/config.json` inside the app sandbox; write it with `adb shell run-as com.sigkitten.litter.android ...`. When the collector runs on the host machine, use `http://10.0.2.2:8585` from the Android emulator and `http://127.0.0.1:8585` from the iOS simulator.
-- A minimal debug config should set `enabled: true`, `collector_url`, `min_level: "DEBUG"`, and stable `device_id` / `device_name` fields so batches can be filtered reliably.
-- After launch, verify upload by checking that `log-spool/pending` drains, then query the collector for the target `device_id`. If you need direct storage inspection, query `/tmp/mobile-log-collector-e2e/collector.sqlite3` and decompress batch files under `/tmp/mobile-log-collector-e2e/batches/...`.
+- Mobile logs now stay local: use Xcode/device console for iOS, Logcat for Android, and normal Rust `tracing` output instead of a collector or spool directory.
 
 ## Coding Style & Naming Conventions
 - Swift style follows standard Xcode defaults: 4-space indentation, `UpperCamelCase` for types, `lowerCamelCase` for properties/functions.
