Pass 4 collects relation jobs, bbox-scans them against the RAM stores,
sorts by NL-spiral distance and publishes store/spool-frontier.txt (key
of the first unfinished relation; spool flushed before every publish).
pbf-base slices a LIVE store behind that gate (--bbox only, torn-tail-
tolerant block reads, pid-scoped sort chunks so concurrent slices never
clobber shared edge blocks), and mapfleet claims block per cell on the
frontier instead of waiting for the whole spool.
Pass-granular resume: passes 2/3 stamp exact spool block lengths +
counters + stats; a restart rolls the spool back to the newest stamp
and reruns only the remaining passes (unit tests + crash drill).
Weave fixes from the Luxembourg end-to-end smoke run: bake outputs land
via temp+rename so the ledger name never exists half-written, and
transmux verification now checks the union of ALL sources with first-
source-wins ownership (it compared source 0 alone and failed every
multi-source weave).
Also: pass-4 worker clamp 12→14, dead paged NodeStore/WayStore and
emit_lines/emit_polygons deleted (flat stores/prepare_* replaced them),
mapfleet --pbf + startup chunk sweep + end-of-spiral drain and final
weave, world-build.sh refreshes the -run binary copies.
