Two cleanup items rolled together:
+
+**Errno constants (audit item #23):**
+- Magic numbers (`4` for EINTR, `9` for EBADF, `28` for SIGWINCH, `1` for SIGHUP, `32` for EPIPE) appear inline across `lib/src/pty/session.dart` and `lib/src/pty/native_pty.dart`.
+- Centralize them in `lib/src/pty/errors.dart` or a sibling `posix.dart` as named constants.
+- Existing `lib/src/ipc/errno_mapping.dart` already has a `PosixErrno` class — extend it or move to a shared location both layers import from.
+
+**Logger standardization (audit item #22, partial #26):**
+- `lib/src/ipc/server.dart` uses `stderr.writeln(...)` directly; the rest of the daemon either uses no logger or a custom one.
+- The Flutter-host process often consumes stderr, so log lines disappear silently.
+- Pick one logger interface (kernel `log` already exists for the app side), wire `DaemonServer` and the daemon-side handlers to use it.
+- Dispatch error messages should prefix with the request `cmd` so log correlation works (audit item #26).
