Merged via /merge-batch (lote 2026-08-26, v3.8.51). Boarded no worktree combinado junto com outras ~30 PRs; validação única: typecheck/complexity/cognitive-complexity/changelog-integrity verdes, file-size rebaseado onde necessário (crescimento legítimo), lint com os mesmos 228 achados pré-existentes confirmados via sonda contra o tip puro (não introduzidos por este lote), e ~370 testes focados (unit + vitest) passando. Obrigado pela contribuição.

// DuckDuckGo Duck.ai model catalog helpers (pure — no network, no DOM stubs).
|
|
// Wire ids captured live from GET /duckchat/v1/models on 2026-08-26; that
|
|
// endpoint requires no VQD/challenge token, so the executor re-validates the
|
|
// requested model against it at runtime (see getLiveModelIds in duckduckgo-web.ts)
|
|
// and this static map stays as the offline fallback.
|

|
// #4037: the real served x-fe-version token has a 20-hex tail (e.g.
|
|
// `serp_20250401_100419_ET-19d438eb199b2bf7c300`); an earlier `{40}` requirement
|
|
// never matched the live token, so the scrape silently fell back to a hardcoded
|
|
// default. Bounded `{20,40}` keeps the pattern ReDoS-safe.
