Phase 2 of the filament_id cleanup (31 collision groups, all one mechanism:
material-class ids on shared fdm_filament_* templates collapsing HF/-CF/
Prusament lines onto one id, plus 3 overclaims). 18 new @base family roots
(owner generic keeps the legacy id, 12 impostor families get deterministic
mints), 72 config-neutral inherits repoints, 6 template filament_id keys
removed (only where every id-less inheritor is covered by a new root;
fdm_filament_asa/pc keep theirs for the frozen Prusament @XL riders),
3 compatible_printers trims on MINIIS printers covered by dedicated @MINIIS
variants. Frozen name-shaped and _NN per-variant ids stay byte-identical.
Verified: config-equivalence gate zero unexpected diffs; extra check exit 0;
--check exit 0; validator -l 2 exit 0; extended -f -v Prusa exit 0 (was 31
groups / 1035 printer-level errors on the pre-apply copy).
