A worker that is +# steered back into work after its PR handoff is not counted again. +# The declaration is matched by the spawning clone's directory name, so clones +# of one origin share the cap only when they use that same directory name. A +# clone of that origin under a different directory name finds no declaration +# and is not capped, though its workers still count as holders for a +# same-origin clone that is capped. +# A record whose project directory no longer exists cannot be matched and holds +# no place. Remote homes are never walked, because their workers run on another +# machine. +# +# Race safety: bin/fm-spawn.sh evaluates admission while holding the shared +# project lock and keeps holding it until the new task record is published, so +# two concurrent spawns for one project can never both publish from the same +# count. A spawn on an uncapped project can still publish a holder for a capped +# same-origin clone, so every backend takes that lock whenever the declaration +# caps any project; Orca, which otherwise never takes it, is included. Freeing a +# place needs no lock, because removing a record or adding pr= only ever lowers +# the count. +# +# Requires bin/fm-wake-lib.sh (root home, local homes, project lock path), +# bin/fm-secondmate-registry-lib.sh (which the local-homes walk reads), and +# bin/fm-backend.sh (fm_meta_get) to be sourced first.
