Harness bugs I hit while running many concurrent coding agents, reproduced, fixed and sent upstream (why):

Project	Contribution	Status
oh-my-pi ★35k	Keep read on the runtime worker for regular-file input
	Unblock mapfile/readarray on process substitution
	Report the persisted value a config save replaces
	Return a re-tasked agent's latest result from agent://
	Count argv/envp pointers so xargs splits large inputs
	Let cancelled jobs run TERM cleanup before a hard kill
	Stop IRC-answered agent wakes reporting "no output"
jcode ★20k	Group contiguous TUI typing into one undo step
	Restore rustfmt on CI
ts-rs ★1.9k	Remove trailing spaces before documented fields
opentelemetry-rust ★2.7k	Keep a failed batch from being reported as a successful flush
flutter ★180k	Keep SDK git queries from reading a git hook's repository

Also reported: worktree clones copying .env secrets · disk exhaustion from per-worktree build caches
