about

nx_research_fork_fetch.nx -- RESEARCHER GROWTH rung: PROCESS-ISOLATED fetch. Each source is fetched in a FORKED CHILD that does one fetch + sys_exit -- so every TLS mmap the fetch allocates is freed on child exit and the PARENT never accumulates the per-fetch leak (the ceiling that capped pass size). Result crosses the process boundary via the saved file. This makes fetch passes UNBOUNDED + isolates failures (a child SIGTERM can't kill the run). The next rung is N children in flight (parallel) -- safest NAS-side, where TLS-CPU contention isn't a factor. [[feedback-grow-researcher-team-continuously]] expect_exit: 0 license_tier: ORIGINAL
