Exchange handler to use the documented emitted codes consistently: replace

`type`-based control flow to normalized error subclasses. Clarify that generic
`AuthError` flows, including Custom Token Exchange, should inspect `code` for
OAuth error values, while preserving `code` as the raw platform or wire
diagnostic for normalized errors.
- Around line 684-710: Update the README error-handling example and surrounding
description so it does not call the shown switch exhaustive while it contains a
default branch. Either describe WebAuthErrorCode as supporting exhaustive
handling, or handle every code explicitly and add a never guard; anchor the
change to the WebAuthErrorCode/WebAuthErrorCodes example.
In `@src/__tests__/publicApiSurface.spec.ts`:
- Around line 208-212: Update the test around “exposes the default export under
a named alias” to use the TypeScript checker to resolve the symbols for “Auth0”

existing surface-presence checks only if needed for setup.
In `@src/core/models/MyAccountError.ts`:
- Around line 158-166: Update the MyAccountError parsing logic to read the RFC
7807 parsed.status value before falling back to parsed.statusCode, while
retaining originalError.status as the final fallback for compatibility. Ensure
the resulting statusCode drives ERROR_CODE_MAP/fromStatusCode classification,
and add a regression test covering parsed status 401 with AuthError.status 0.

Align the handler with the documented Custom Token Exchange codes.
This handler checks unsupported_grant_type. The reference at lines 1209-1226 lists unsupported_token_type and unauthorized_client instead. The documented alerts for unsupported token types and disabled clients will not run for the listed codes.

Limit the type guidance to normalized error subclasses.
Custom Token Exchange throws AuthError and uses OAuth error values in code, as shown in EXAMPLES.md lines 1005-1023. The instruction to “never” switch on code conflicts with that supported flow.
State that consumers must use type for normalized error subclasses and use code for generic AuthError flows such as Custom Token Exchange.

Fair point — a default branch does defeat exhaustiveness checking. Reworded so the prose no longer claims the shown example is exhaustive; it now explains that omitting default (with every case handled) is what actually gets you the compile-time guarantee, and flags that the shown example trades that off for brevity

@NandanPrabhu, thanks for the correction. The revised wording accurately explains the compile-time guarantee and the example’s brevity tradeoff.

Use the full opaque My Account type value in both examples.
My Account API error types use the A0E-<status>-<numeric> format. A0E-401 omits the numeric component and can mislead users about the raw typeUri value.

Learning: In `src/platforms/web/adapters/WebMyAccountClient.ts`, My Account API errors expose opaque `A0E-<status>-<numeric>` types (for example, `A0E-401-0001`) rather than semantic passkey identifiers. Web passkey flows must use `PasskeyError`'s phase-specific fallback type: `PasskeyErrorCodes.CHALLENGE_FAILED` for `passkeyEnrollmentChallenge` and `PasskeyErrorCodes.EXCHANGE_FAILED` for `enrollPasskey`. Native passkey codes retain their existing direct mapping.

Good catch, this was a real bug — a spec-compliant { "status": 401 } problem document was falling through to UNKNOWN_MY_ACCOUNT_ERROR whenever AuthError.status was 0. Now reads parsed.status first, then parsed.statusCode as a compatibility fallback, then originalError.status. Added a regression test for exactly the scenario you described (parsed status 401, AuthError.status 0).

@NandanPrabhu, confirmed. The fallback order now supports RFC 7807 status values and preserves statusCode compatibility. The regression test covers the reported 401 and AuthError.status === 0 case.

Deleting src/exports/ breaks yarn docs (it's typedoc's entry point) and flattens the Classes/Enums/Hooks/Interface docs grouping. Can we keep the barrel, with each group re-exporting only from src/index.ts so it can't drift, and cover it in the freeze test?

You're right, this broke yarn docs outright (the configured TypeDoc entry point pointed at a file that no longer existed). Went with your suggested fix: restored src/exports/classes.ts/hooks.ts/enums.ts/index.ts as thin re-exports of src/index.ts (not the internal modules), and interface.ts as export type * from '../index' so it can't drift at all — if a name is ever renamed/removed from src/index.ts without updating these, it's a compile error, not a silent doc gap. Added src/exports/__tests__/index.spec.ts as the freeze test you asked for, and confirmed yarn docs builds clean again

MyAccountErrorCode vs MyAccountErrorCodes differ by one character. The repo also merges the two under one name (MfaFactorType, DeliveryMethod), so which convention is canonical for v6?
There was a problem hiding this comment.
Kept the split naming for now — it's consistent with all five sibling classes in this same taxonomy (WebAuthErrorCode/WebAuthErrorCodes, MfaErrorCode/MfaErrorCodes, etc.), so within the error taxonomy specifically, this is the canonical pattern rather than an outlier. Unifying with the merged pattern (MfaFactorType, DeliveryMethod) across the whole SDK is a fair question but feels like a separate, broader decision — happy to open a follow-up issue if you think it's worth standardizing on one pattern SDK-wide.

Prepares the v6 public contract so post-GA changes cannot break consumers accidentally (SDK-10043). Error taxonomy: - Add MyAccountErrorCodes, completing the set of six code objects. MyAccountError previously exposed a raw RFC 7807 type URI on `type`, unlike every sibling class; `type` is now a normalized code and the original URI is preserved on the new `typeUri` property. - Export a derived union per class (WebAuthErrorCode, ..., MyAccountErrorCode) computed from the constants object, so the runtime values and the type cannot drift, and narrow each class's `type` to its union. - Add Auth0ErrorCode as the umbrella union, and bring TimeoutError into the taxonomy with `type: 'TIMEOUT_ERROR'`. Surface cleanup (122 -> 136 exports): - Un-export four internal wire/config shapes: NativeAuth0Options, WebAuth0Options, NativeCredentialsResponse, SSOCredentialsResponse. - Export types that already appeared in public signatures but were unreachable from the entry point: IAuth0Client and its five sub-provider siblings, Auth0ContextInterface, AuthState, SafariViewControllerPresentationStyle. - Replace the blanket `export * from './types'` with explicit sectioned exports, and delete the dead, drifted src/exports/ barrel files. - Rename DPoPHeadersParams to DPoPHeadersParameters for consistency with the other `...Parameters` types, keeping a deprecated alias. Freeze mechanism: - publicApiSurface.spec.ts asserts the exact export list via the TypeScript compiler API, so type-only regressions are caught too. - errorTaxonomy.spec.ts asserts the structural invariants: every class carries a normalized `type`, falls back to a terminal unknown code, and keeps codes unique across classes except for three documented overlaps. Docs: document the taxonomy and the type/code/typeUri distinction as the stable contract, and fix two example blocks that referenced exports which never existed (MyAccountErrorCodes before this change, and AuthenticationException / AuthenticationErrorCodes, which do not exist at all). BREAKING CHANGE: MyAccountError.type is now a normalized MyAccountErrorCodes value rather than an RFC 7807 type URI; read `typeUri` for the raw URI. The internal types NativeAuth0Options, WebAuth0Options, NativeCredentialsResponse and SSOCredentialsResponse are no longer exported.
Restore src/exports/*.ts as thin re-exports of src/index.ts (rather than internal modules) so `yarn docs` builds again and TypeDoc's Classes/Enums/ Hooks/Interface grouping survives the barrel deletion; cover it with a freeze test so it can't silently drift from the frozen surface again. Read the RFC 7807 `status` field before the nonstandard `statusCode` in MyAccountError, so a spec-compliant problem document is classified correctly even when the underlying AuthError.status wasn't populated. Strengthen the "Auth0 is a named alias for default" test to compare resolved TypeScript symbols instead of only checking both names exist. Fix the Custom Token Exchange example in EXAMPLES.md to use the documented unsupported_token_type/unauthorized_client codes, correct the contradictory error-taxonomy guidance in README.md (code-vs-type switch scope, a false exhaustiveness claim), and fix the truncated typeUri example in both docs. Document the MyAccountError.type breaking change and the four removed exports in MIGRATION_GUIDE.md, and correct its stale claim that the newly-exported client interfaces were never part of the entry point.

Use the exported type name MyAccountErrorCode.
Line [259] calls MyAccountError.type a MyAccountErrorCodes value. The implementation declares this property as MyAccountErrorCode; MyAccountErrorCodes is the constants object used for comparisons. Update the prose to distinguish the union type from its constants.

@subhankarmaiti Good catch — added §11 ("Public API surface freeze & My Account error normalization") to MIGRATION_GUIDE.md covering both: the MyAccountError.type change (RFC 7807 URI → normalized code, with a before/after diff) and the four removed exports (NativeAuth0Options, WebAuth0Options, NativeCredentialsResponse, SSOCredentialsResponse). Also fixed §10's claim that the newly-exported client interfaces "were never exported" — that's no longer true after this PR, so I corrected it in the same edit. |

Summary
Before v6 GA, freeze the public surface so post-GA additions can't happen by accident, and give consumers one predictable error contract across iOS, Android, and web.
MyAccountErrorCodes(previously referenced in docs but never implemented) and mappedMyAccountError.typeonto normalized codes instead of an RFC 7807 URI, preserving the URI on a newtypeUrifield. Exported six derived code unions (WebAuthErrorCode,CredentialsManagerErrorCode,DPoPErrorCode,MfaErrorCode,PasskeyErrorCode,MyAccountErrorCode) plus anAuth0ErrorCodeumbrella, and narrowed each error class'stypefield fromstringto its own union.TimeoutErrornow has atypeso it joins the taxonomy.NativeAuth0Options,WebAuth0Options,NativeCredentialsResponse,SSOCredentialsResponse), deleted the dead/driftedsrc/exports/barrel, and added 18 exports for types that already appeared in public method signatures but were unreachable fromsrc/index.ts(client interfaces,Auth0ContextInterface,AuthState, a namedAuth0export, etc.).
