The root barrel is now core-only and side-effect free: types,
createModels/createProvider, auth substrate, lazyStream/lazyApi, faux,
utils. Generated catalogs, api-registry, env-api-keys, images, global
stream functions, and per-API lazy wrappers leave the root.
New @earendil-works/pi-ai/compat preserves the old surface verbatim as
a strict superset of the root: api-dispatch stream/complete with env
key injection, the builtin registration side effect (skip-if-present so
it cannot clobber earlier overrides), deprecated getModel/getModels/
getProviders aliases of the new getBuiltin* reads in providers/all,
lazy api wrappers + setBedrockProviderModule, and image generation.
Compat dies with the coding-agent ModelManager migration.
Packaging: exports map gains ./compat, ./providers/*, ./api/*;
sideEffects array lists only the effectful modules.
Old-global imports across agent/coding-agent/examples and pi-ai tests
switch to /compat (path-only; compat is a superset). The coding-agent
extension loader resolves the pi-ai ROOT specifier to compat, so
existing user extensions using the old global API keep working at
runtime until compat is removed. vitest configs alias /compat to src;
browser smoke imports old globals from /compat.
anthropic, openai-codex, and github-copilot flow modules gain OAuthAuth
exports (login/refresh/toAuth) wired to the prompt()/notify() login
callbacks, making the lazyOAuth attachments on the provider factories
functional. Copilot's modifyModels baseUrl rewriting becomes toAuth()
returning ModelAuth.baseUrl derived from the token proxy endpoint.
Callback-server flows race a manual_code prompt and abort it through
AuthPrompt.signal once the flow settles; OAuthAuth has no
usesCallbackServer flag. The old OAuthProviderInterface exports stay
unchanged until the coding-agent migration.
