Assert the saved expiry timestamp.

Both verifications accept any expiresAt value. They pass if the ViewModel saves null, an already-expired value, or the wrong buffer. Capture the argument and assert that it is near the test start time plus 14 minutes.

• application/features/auth/src/jvmTest/kotlin/io/writeopia/auth/menu/AuthMenuViewModelTest.kt#L172-L172: assert the expiry saved for the successful token-persistence path.
• application/features/auth/src/jvmTest/kotlin/io/writeopia/auth/menu/AuthMenuViewModelTest.kt#L90-L90: assert the expiry saved for the admin-key login path.

As per path instructions, review test code for adequate test coverage for edge cases.

capture the expiresAt argument passed by authRepository.saveTokens in both
successful token-persistence and admin-key login paths, then assert it is
non-null and near the test start time plus 14 minutes, allowing an appropriate

9-24: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Fail fast with a clear message when JWT_SECRET is missing.

System.getenv("JWT_SECRET") returns a platform type. If the variable is not set, accessSecret is null, and Algorithm.HMAC256(accessSecret) fails during JwtConfig initialization. The result is an ExceptionInInitializerError at the first token operation instead of a readable startup error. Also note that refreshSecret falls back to accessSecret, so one key signs both token types; the type claim is the only separation.

🛡️ Proposed change

-    private val accessSecret = System.getenv("JWT_SECRET")
-    private val refreshSecret = System.getenv("JWT_REFRESH_SECRET") ?: accessSecret
+    private val accessSecret: String = requireNotNull(System.getenv("JWT_SECRET")) {
+        "JWT_SECRET environment variable is required"
+    }
+    private val refreshSecret: String = System.getenv("JWT_REFRESH_SECRET") ?: accessSecret

Use withJWTId and getId for the JWT ID claim.

Ktor 3.5.2 supplies java-jwt 4.6.0, which accepts "jti" through withClaim. The current code does not fail because of a reserved-claim rejection. Use the dedicated APIs to express the registered JWT ID contract directly.

94-97: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Use a fast digest for refresh-token hashes.

RefreshTokenService.hashToken calls HashUtils.hashPassword, which uses PBKDF2-HMAC-SHA512 with 100,000 iterations. Token generation calls it during login and email confirmation. Refresh validation calls it on every refresh, then calls it again when issuing the replacement token. Because each token includes a newly generated UUID token ID, use SHA-256 or another fast cryptographic digest instead.

Inline comments:
In
`@application/core/auth_core/src/jsMain/kotlin/io/writeopia/auth/core/manager/LocalStorageAuthRepository.kt`:
- Around line 173-182: Update logout to call clearTokens() instead of
referencing the removed KEY_TOKEN constant, ensuring it clears the access token,
refresh token, and expiry timestamp through the existing
LocalStorageAuthRepository.clearTokens implementation.

In
`@application/core/persistence_sqldelight/src/commonMain/sqldelight/io/writeopia/app/sql/TokenEntity.sq`:
- Around line 3-5: Add a SQLDelight migration after migration 2 for token_entity
that preserves existing token values by renaming or copying token into
access_token, then adds nullable refresh_token and access_token_expires_at
columns matching TokenEntity.sq. Ensure upgraded databases support the current
TokenEntity queries without losing stored access tokens.

In
`@application/features/global_shell/src/commonMain/kotlin/io/writeopia/global/shell/viewmodel/GlobalShellKmpViewModel.kt`:
- Around line 513-519: Update deleteAccount to capture the refresh token and its
user context before starting the nested logout coroutine; use that captured
context for authApi.logout, then unselect workspaces and clear tokens without
performing a later authRepository.getRefreshToken lookup.

In
`@backend/core/auth/src/main/java/io/writeopia/api/core/auth/routing/AuthRouting.kt`:
- Around line 111-114: Update the exception handling around the refresh-token
and logout request flows to catch BadRequestException separately and respond
with HttpStatusCode.BadRequest; retain the general Exception handlers for
genuine server failures returning InternalServerError. Apply this to the
handlers containing call.receive<RefreshTokenRequest>() and POST
/api/auth/logout.

In
`@backend/core/auth/src/main/java/io/writeopia/api/core/auth/routing/EmailRouting.kt`:
- Around line 35-48: Update the success log in the email confirmation flow to
omit request.email and identify the confirmed account using user.id instead;
keep the existing token generation and response behavior unchanged.

In
`@backend/core/auth/src/main/java/io/writeopia/api/core/auth/service/RefreshTokenService.kt`:
- Around line 53-77: Update validateAndRotate to perform revocation and
generateAndStoreTokens within a single writeopiaDb.transaction, using an atomic
conditional revoke or equivalent locking/recheck so concurrent requests cannot
both rotate the same token. Add a lookup by token ID that includes revoked rows;
when a matching revoked token is found, call revokeAllUserRefreshTokens for its
user before returning null, while preserving null for absent or invalid tokens.

In
`@backend/core/database/src/main/sqldelight/io/writeopia/sql/RefreshTokenEntity.sq`:
- Around line 1-11: Add a foreign-key reference from
refresh_token_entity.user_id to user_entity(id) with ON DELETE CASCADE, or
update deleteUserById to call revokeAllUserRefreshTokens before deleting the
user; ensure deleted accounts cannot retain usable refresh tokens.

In
`@plugins/writeopia_network/src/commonMain/kotlin/io/writeopia/sdk/network/injector/WriteopiaConnectionInjector.kt`:
- Around line 109-113: Update the bearer authentication configuration used by
ApiInjectorDefaults.httpClient so cached Ktor bearer tokens cannot survive
AuthRepository.clearTokens(); disable token caching or explicitly clear the
bearer provider cache during logout, while preserving the existing loadTokens
behavior.

In
`@plugins/writeopia_network/src/commonMain/kotlin/io/writeopia/sdk/network/oauth/BearerTokenHandler.kt`:
- Around line 6-8: Add default implementations for the new BearerTokenHandler
methods getRefreshToken and refreshTokens so existing implementations remain
source-compatible; use appropriate fallback behavior consistent with the
existing TokenRefreshResult contract.

In
`@plugins/writeopia_serialization/src/commonMain/kotlin/io/writeopia/sdk/serialization/data/auth/AuthResponse.kt`:
- Around line 8-9: Preserve AuthResponse’s existing public token API by
retaining a deprecated token compatibility accessor and constructor alongside
the new accessToken and refreshToken fields. Ensure the constructor parameter
order remains compatible with existing positional calls, particularly
writeopiaUser, and avoid introducing a breaking change in this plugins API.
