In Resolution Remove the fixed Full details: Cmux Algorithmic ComplexityExplanation The new production script introduces a nested collection scan at Resolution Resolve the selected bundle's app path once and compare each process against that single target path, or build an indexed/prefix lookup for multiple paths. Cache the installed-app lookup outside the polling loop, and refresh only the process snapshot as needed. Keep the total work linear in the process and app collections. Full details: Cmux User-Facing Error PrivacyExplanation The new CLI emits user-visible command output with upstream tool and service names. For example, it prints Resolution Sanitize the script's runtime output. Use generic cmux/device terms such as “device logging tools are unavailable,” “could not resolve the device,” and “the device is not connected; reconnect it and retry.” Do not include upstream tool or service names, raw UDIDs, internal paths, or bundle details in errors. Avoid printing unredacted journal payloads in normal command output, or apply an explicit safe redaction before displaying a tail. Keep exact dependency-install commands and implementation details in the exempt operational runbook or sanitized diagnostics.

Replace the polling startup wait with an explicit readiness signal.
Line 232 polls process state with a fixed one-second delay. A launch that takes longer than --wait-seconds fails even when it later succeeds. Use an owner-provided lifecycle notification, or fail closed and require the caller to start INTERNAL before invoking this script. Remove --wait-seconds and update its documentation.
As per coding guidelines, “Do not use fixed sleeps, delayed dispatch, timers, polling, or wall-clock waits to mask ... startup ... races.”

Refresh the PID filter after process restarts.
resolve_target_pids runs only before the long-lived idevicesyslog | awk pipeline starts. If the INTERNAL process relaunches with a different processIdentifier, awk does not add the new PID to wanted. It can therefore discard the new cmux[PID] lines while the stream remains active. Refresh the PID set from an explicit lifecycle signal, or require a new invocation when the process changes. Add a test for an INTERNAL restart during an active stream.

🪛 ast-grep (0.45.2)
[warning] 241-241: set +e (or set +o errexit) disables the shell's errexit option, so the script keeps running after a command fails. This masks failures of security-critical operations (downloads, signature/checksum verification, permission changes, cleanup of secrets), letting the script proceed with a bad or insecure state. Leave errexit enabled (set -e / set -euo pipefail), or handle failures explicitly with if/|| and an explicit exit instead of globally turning off failure detection.

Ctrl-C ignored during process wait
Low Severity
The INT/TERM trap runs cleanup and then returns, so the script keeps running. Ctrl-C during UDID resolution or the process wait is swallowed instead of stopping the viewer.

Cleanup rm errors on empty paths
Low Severity
cleanup always passes all four snapshot variables to rm -f, including ones still empty. On a normal run some temps are never created, so exit prints invalid-argument errors from rm.

Adds scripts/stream-ios-logs.sh for a low-overhead live iROH journal stream from cmux INTERNAL on the attached iPhone.
The command resolves the CoreDevice identifier to the USB UDID required by idevicesyslog, scopes output to the INTERNAL bundle process PID, supports an optional journal tail snapshot, and documents usage in the iROH soak runbook.
Verification: shellcheck, help/argument checks, physical-device journal tail transfer, USB syslog connection, and PID filter behavior.
