assertNoAccountIdentityCollisioncallstargetAccountIdentityon every candidate row found by index. If a candidate belongs to a provider that is absent fromproviderIssuers, the call throwsMissing trusted issuer mapping for providerId <candidate provider>. The operator then sees an error for a provider that is not part of the page being processed. The migration guide tells operators to fix "that record or mapping and rerun the same page", so a misleading provider name costs time during a maintenance window.Consider wrapping the candidate resolution to state that the failing row is a collision candidate.

Thanks for working on this. Looking forward to 1.7, particularly the MCP authorization improvements and hydrateSession. Would love to see this land! I checked out 4e8f35a and ran the package build and test suite locally with 1.7.1. The build passed, with 259 tests passed, 31 skipped, and no type errors.

- update better-auth, @better-auth/core and test-utils to 1.7.7 - strip modelKey (added in 1.7.6) before calling component functions, the component validators rejected it on findOne/findMany/count/ deleteMany/updateMany - implement consumeOne natively on deleteOne. Better Auth's atomic fallback guards on every row field including _creationTime, which the where validators reject, so every verification consumption failed - no-op consumeOne/incrementOne in query context, from convex#430 - match the auth-state: prefix on OAuth state verification rows in tests - add tests for atomic writes against the component schema Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Unique checks only looked at field-level `unique` by schema key, so a unique field renamed with `fieldName` (e.g. user.email -> email_address) was never checked, and Better Auth 1.7 table-level unique indexes (device authorization `deviceCode`/`userCode`) were neither enforced nor given a schema index by the generator. Checks now cover field-level and table-level (including compound) constraints, using database field names and the merged document on update. Schemas generated before this have no index for table-level constraints, so the check falls back to a scan with a warning instead of failing writes. From upstream PR get-convex#430.

This lets convex-test's defineTestApp infer the component's API when the test module is passed directly in its components map.
Raise the supported baseline to >=1.7.7 <1.8 and strip modelKey metadata before calling Convex component functions. Remove the obsolete required-issuer migration while retaining optional legacy issuer data and provider export tools. Update generated schemas, examples and the migration guide. Exercise required fields and compound constraints through an explicit custom test profile.
Resume from continueCursor rather than the splitCursor inside a page that has already been returned. Cover full and limited reads, count, updateMany and deleteMany across a filtered page split.
Treat absent fields as null in static eq-null and ne-null comparisons. Better Auth's refresh rotation guards an unset revoked field with eq null, so valid tokens were rejected even with native incrementOne. Add regression cases for absent, explicit-null and set fields, including repeated guarded claims. Indexed null and in/not_in behavior remain separate.

Summary
Support Better Auth
>=1.7.7 <1.8.0. StripmodelKeyfrom Convex function arguments and add native atomicconsumeOneandincrementOneoperations. Update schema generation, plugin constraints, React client types, Generic OAuth callbacks, examples, and Local Install exports.Fix two adapter issues exposed by upgrade testing:
continueCursorso previously returned rows are not repeated.eq null/ne nullfilters so OAuth refresh-token rotation succeeds.Fix OAuth provider discovery for eager and lazy route registration. Document plugin configuration and database-backed signing keys, keeping the provider issuer and Convex JWT issuer distinct. Includes the upstream test-helper change from #447.
Migration
Remove the obsolete issuer backfill, helpers, and indexes: 1.7.7 uses
(providerId, accountId)for account identity. Retain optionalaccount.issuerfor existing early-1.7 data. Keep guidance for account audits, Microsoft account IDs, account selectors, and Generic OAuth changes.Document the Local Install migration from
oidcProviderto@better-auth/oauth-provider: export clients, clear legacy provider records, re-register clients, and issue new secrets/tokens. Include temporary schema and cleanup instructions that preserve existing users, sessions, signing keys, and custom fields/indexes. Apps that only sign in through external providers can skip this conversion.Clarify Generic OAuth identity mapping and PKCE, Expo asynchronous cookies, and two-factor response handling. Link existing standalone OAuth provider users to upstream client migrations, with temporary Convex schema guidance, and document signed consent-query verification. Note that SCIM requires native interactive transactions and remains unsupported; adding SCIM support is outside this PR.
Testing
External IdP logins and hosted custom-base-path/non-RS256 provider flows were not tested. Static JWKS is unsupported by the documented provider configuration.

Related work: #444 (1.7 upgrade), #380 (OAuth/MCP), and @FatahChan’s #396 (React typing). Broader cleanup and #404/#411 remain separate.
