- After 5 sessions, the diagnosis has been stuck because the only diagnostic channel is the child's stdout/stderr
PIPEs — and those pipes are exactly the suspect. The live child reports "empty output" precisely because whatever is
wrong happens on the pipe/handle boundary it inherits from the live MCP stdio server.
- Two live-only variables remain unreplicable from bash: (1) the worker inherits the orchestrator's stdin handle,
which is the live MCP stdio pipe Claude Code actively reads/writes; (2) Claude-Code-injected process state. The fix
must (a) remove the inherited-stdin variable (stdin=DEVNULL — correct daemon hygiene regardless), and (b) bypass pipes
for diagnostics by having the worker write a startup trace to a file, so the next live attempt is self-diagnosing no
matter what the pipes do.
