Greptile Summary

This PR updates the Go SDK to v5.1.0, adding new endpoints (CreateSesProvider, UpdateSesProvider, UpdateOAuth2Server, UpdatePasswordStrengthPolicy, GetAuditsDB) and a new PolicyPasswordStrength model. It also introduces a structural change where WithProject now stores the project ID in a Config map instead of directly in the global Headers map, with each service method reading Config["project"] to set the X-Appwrite-Project header per-request.

• Header refactor: client.Config map introduced; WithProject and other With* option setters now write to Config alongside Headers. All 81 changed service files have been consistently updated to include "X-Appwrite-Project": srv.client.Config["project"] in every request headers block.
• New endpoints: CreateSesProvider/UpdateSesProvider in messaging, UpdateOAuth2Server and UpdatePasswordStrengthPolicy in project, and GetAuditsDB in health — all following existing SDK patterns.
• Model updates: models/project.go adds eight new OAuth2 server fields and moves Region earlier in the struct; new models/policyPasswordStrength.go covers the password-strength policy response.

Confidence Score: 4/5

Safe to merge after fixing the []interface{}{} type in the OAuth2 server docs example; all runtime code is correct and consistent.

The header-per-request refactor is applied uniformly across all service files — every method that makes an HTTP call now explicitly carries X-Appwrite-Project. New endpoints and the new model are correctly implemented. The one concrete error is in the generated docs example for UpdateOAuth2Server, which passes []interface{}{} where []string is required, meaning anyone who copies that snippet will get a compile failure.

docs/examples/project/update-o-auth-2-server.md — type mismatch on the Scopes argument that must be corrected.

Important Files Changed

Filename	Overview
client/client.go	Adds Config map[string]string field to the Client struct and bumps SDK version to v5.1.0. The Config map stores per-request values like project that individual service methods now read to set the X-Appwrite-Project header.
appwrite/appwrite.go	Changes WithProject to store value in Config["project"] instead of Headers["X-Appwrite-Project"]. Other With* setters mirror the same pattern, also storing values in Config. This is a structural refactor that requires all service methods to explicitly read from Config per-request.
project/project.go	Adds UpdateOAuth2Server and UpdatePasswordStrengthPolicy methods plus backfills X-Appwrite-Project header in all existing methods. New methods follow established patterns correctly.
messaging/messaging.go	Adds CreateSesProvider and UpdateSesProvider methods and backfills X-Appwrite-Project header across all existing provider/topic/subscriber methods. Implementation follows existing patterns correctly.
health/health.go	Adds GetAuditsDB method and backfills X-Appwrite-Project header in all existing health-check methods.
models/policyPasswordStrength.go	New model for password strength policy with fields Id, Min, Uppercase, Lowercase, Number, Symbols. Follows the existing model pattern with New() and Decode() methods.
models/project.go	Moves Region field earlier in the struct, relocates BillingLimits, and adds eight new OAuth2 server fields. JSON tags are correct.
docs/examples/project/update-o-auth-2-server.md	Contains a type mismatch: Scopes is passed as []interface{}{} but the method takes []string. This example would not compile.
docs/examples/messaging/create-ses-provider.md	New example for CreateSesProvider. Follows same documentation pattern as other provider examples.
docs/examples/health/get-audits-db.md	New documentation example for the GetAuditsDB health check endpoint.

The Scopes option takes []string in the actual method signature (func (srv *Project) WithUpdateOAuth2ServerScopes(v []string)), but the example passes []interface{}{}. Copying this example would result in a compile error.

Suggested change

	project.WithUpdateOAuth2ServerScopes([]interface{}{}),
	project.WithUpdateOAuth2ServerScopes([]string{}),
