Pin the pure-function surface of @cv/domain: the LLM cascade (resolver, seed/consensus, chain-config loader, callWithChain, model catalog, AI LED), salary extraction repair, cell-origin and audit projections, scoring + hard-fact normalization, views rule engine, columns + order + import/export, locale + language helpers, scrape URL normalize, Google Maps directions wrapper, the singleflight compute lock, protected-fields gate, pipeline stage executors + xstate machine, BYOK key helpers, workspace settings helpers, ruler/measure source (with optional typst CLI integration) + fragment cache, font fallback registry, node-to-typst + preview-segments, jobcache row builders + workspace read chain, Zod schema defaults, gateway sinks, slug ID bookkeeping, industries enum, translate, and the cross-bundle equivalence check that catches bundler drift.
