…ore 2.5.0) `bun run eval:vibes` asserts cultural/mood references map to the structured `styles` attribute (quiet luxury→minimalist+classic, old money→classic+preppy, y2k→y2k, cottagecore→romantic+bohemian, coastal grandmother/clean girl→minimalist+classic). Lenient overlap assertion (LLM-driven). The eval surfaced a real limitation: gemini-3.1-flash-lite degrades the WHOLE NLQ parse to nothing on very short (2-word) queries — vibe or not (verified: "streetwear hoodie"/"cottagecore dress"/ "quiet luxury" return no parse; "blue cotton shirt" parses fine). So those fall back to the raw embedding (no styles). Realistic 3+ word vibe queries expand reliably and are the gating contract; the 2-word cases are marked `flaky` (reported, non-gating) until the NLQ is hardened for short input.

bun run eval:vibesas a regression guard for the core 2.5.0 vibe→styles contract. Gates on realistic vibe queries (5/5 pass); reports that flash-lite degrades the NLQ on 2-word queries (verified, non-gating). No core change. 🤖 Generated with Claude Code
