.run/maintenance.sh (what runs) and tools/lanes/maintenance.sh (a pre-S59 copy) had
diverged. The 150->50 threshold tune landed on the stale copy and was then copied over
the live one, silently reverting five S59 fixes:
* the R47 shape filter (staging fell back to status=='AGREE' alone — the exact defect
that staged 82 hopeless drafts every 45 minutes)
* the R48 (binary, fn) keying (bare-fn keys collide across overlays)
* reloc --fix MISMATCH auto-repair (measured 4/4 repaired to AGREE)
* rtu_second_chance (re-judges standalone COMPILE-FAILs against the real TU)
* fix_tu_ret_decls (the return-type half of the stale-decl wall)
Rebuilt from the S59 lineage with the 150->50 threshold and the periodic fleet R22
re-applied, both paths now byte-identical, `bash -n` clean, and the two-path hazard
documented in the header so the next edit cannot repeat it.
Also: relaunch_drafter_shell.sh 30s -> 5s ready-marker poll; regenerated backlog and
fleet progress artifacts.
