nx_mvault_tag.nx

nx_mvault_tag.nx -- extensible, searchable metadata planes for vault items. DESIGN (operator 2026-07-17: "hammer searchability + extensibility BEFORE the heavy reclassify ... performer/pose/body-type ... booru but far beyond ... lossless language aka hip-to-waist ratios ... feed the future joy classifier"): three ADDITIVE planes over the immutable core record, so new auto-tag capabilities slot in with ZERO schema migration -- FACETS numeric fields (size/recency/popularity/dims) -> SORT KEYS for fast large/recent/popular finding (byte-lex order == numeric). TAGS booru-style OPEN namespaces "ns:value" (performer:/pose:/hair:/ body:/ethnicity:/nipple:/cup:...) -> inverted index per namespace. ATTRS lossless quantitative "key=ivalue/scale" (hip_waist_ratio=700/1000 = exact 0.700, no-float) -> range-searchable. The booru-beyond bit. All CID-keyed + additive; searchability rides the librarian info-finding index (coordinate, don't rebuild). This module is deliberately OPEN -- it hardcodes NO tag list, so performer/pose/body/etc. are just data. license_tier: ORIGINAL
