/**
 * Anthropic model-family rules — which Claude models refuse which
 * request parameters — shared by every caller that builds an Anthropic
 * request: the generation harness's router (`@ggui-ai/ui-gen`), the
 * negotiator's structured call (`@ggui-ai/mcp-server`), and the
 * negotiator/probe tooling. One module instead of a copy per caller:
 * a model the API starts refusing a parameter for is added here once.
 * The families are regexes — a second list of models beside the
 * registry. The forced-tool one stays a regex and is PINNED instead
 * (ggui#1268): a table written from the vendor's pages classifies every
 * Anthropic id the allowlists in `llm-route.ts` can route, and the
 * predicate must agree with it in both directions — so a routable id
 * added without a vendor-quoted row, or a disagreement, fails CI.
 *
 * Lives in protocol beside `llm-route.ts` because model facts live
 * here: the registry rows (`llm.ts`), the allowlists and the
 * Bedrock/OpenRouter shape validators (`llm-route.ts`). Pure string
 * predicates; no SDK, no I/O.
 *
 * **The model lists GROW, and that is the contract.** Each predicate
 * answers "does Anthropic refuse this parameter on this model?", and
 * Anthropic adds models that refuse things. A predicate starting to
 * return `true` for a model id it returned `false` for (a newly listed
 * model, or a newly recognised spelling of one) is an ADDITIVE change
 * under VERSION-POLICY, not a breaking one: callers already handle both
 * answers for every id. What is frozen is the signatures (`string` in,
 * `boolean`/`string` out) and the direction of each answer. Never
 * snapshot a predicate's output as a fixed list.
 *
 * The two directions are not equally safe. Widening (`true` for more
 * ids) is the SAFE direction: a wrong `true` degrades to the permissive
 * request (sampling params omitted, `tool_choice: auto`). Narrowing
 * (`true` → `false`) is the UNSAFE direction: a wrong `false` sends a
 * parameter the API rejects with a 400 — so a narrowing needs the
 * vendor's page quoted on the issue, not only a test. For
 * `normalizeAnthropicModelId`, which returns a string, the matching
 * rule is that a newly recognised spelling maps to the SAME bare id,
 * never a different one.
 */
/**
 * Strip every routing spelling down to the bare Claude API id so the
 * family predicates below see one form: `anthropic/claude-x`,
 * `anthropic.claude-x`, `<profile>.anthropic.claude-x[-vN:M]` for every
 * Bedrock cross-region profile in `BEDROCK_INFERENCE_REGION_PREFIXES`
 * (ggui#1254 — the old two-letter match let `global.` and `apac.` through,
 * so a `global.anthropic.claude-opus-5-5` route sent a forced tool choice
 * and kept its sampling params), a `bedrock/` prefix, and the bare
 * `claude-x` all normalize to `claude-x…`. OpenRouter's dotted versions
 * (`anthropic/claude-opus-5.5`) keep their dot; the predicates accept
 * both. ARNs are left as-is (they name a profile, not a family) and match
 * no predicate.
