Closes #569.
Closes #570.

Scopes temporary legacy-cookie revocation and clearing to its durable farm owner, and treats selector-less mixed cookie generations as ambiguous. Preserves legacy-only and identical-token compatibility.

Tests: dotnet test Cluckwork.sln --configuration Release --no-build --verbosity normal

Summary by CodeRabbit

  • Bug Fixes

    • Improved logout handling for duplicate, legacy, foreign, and farm-specific refresh sessions.
    • Prevented logout from revoking or clearing sessions that do not belong to the signed-in account.
    • Improved protection against refresh-token replay during concurrent logout and refresh activity.
    • Ensured logout remains durable and reliable during concurrent requests or database failures.
  • Tests

    • Added extensive coverage for session ownership, token lineage, replay protection, and logout/refresh race conditions.

📝 Walkthrough

Walkthrough

Logout now uses durable account-scoped refresh-token ownership and lineage fencing. Legacy cookies are cleared only for eligible sessions. Integration tests cover cookie binding, refresh races, and raw SQL safeguards.

Changes

Logout and refresh-token lifecycle

Layer / File(s) Summary
Account-bound logout contract and cookie flow
src/Cluckwork.Application/Common/IIdentityProvider.cs, src/Cluckwork.Api/Endpoints/Auth/AuthEndpoints.cs, tests/Cluckwork.Api.IntegrationTests/RefreshAccountBindingTests.cs, tests/Cluckwork.Api.IntegrationTests/StepUpAuthTests.cs, tests/Cluckwork.Api.IntegrationTests/MustChangePasswordGateTests.cs
Revocation returns token ownership scope. Logout preserves foreign sessions, handles duplicate cookie tokens, and clears cookies only after in-scope ownership is confirmed.
Exact refresh-token lineage fencing
src/Cluckwork.Infrastructure/Identity/IdentityProvider.cs
Revocation follows user-, account-, and epoch-scoped replacement links. PostgreSQL updates fence the live tip and sever visited ancestors atomically. Grace inspection uses fresh snapshots.
Logout and refresh race validation
tests/Cluckwork.Api.IntegrationTests/LogoutRefreshLineageRaceTests.cs, tests/Cluckwork.Api.IntegrationTests/CredentialEpochRaceTests.cs, tests/Cluckwork.Api.IntegrationTests/SecurityEventLoggingTests.cs, tests/Cluckwork.Api.IntegrationTests/StepUpAuthTests.cs
Tests coordinate refresh rotation and logout commands to validate concurrent outcomes, epoch races, and scalar command failures.
Raw-SQL execution and scope guard validation
tests/Cluckwork.Application.Tests/TenantBypass/GuardScanner.cs, tests/Cluckwork.Application.Tests/TenantBypass/TenantBypassAllowListTests.cs, tests/Cluckwork.Application.Tests/TenantBypass/TenantBypassRealTreeTests.cs, tests/Cluckwork.Application.Tests/TenantBypass/Data/tenant-bypass-allowlist.json
Tenant-bypass checks detect low-level raw SQL, require relational execution, validate both scoped CTE update arms, and verify the lineage-fencing method.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 75458

The PR narrows legacy-cookie revocation to the selected farm and rejects ambiguous mixed generations, but edge-case logout requests can still return HTTP 500 when lineage crosses owner or epoch boundaries, while tenant-safety checks may miss some unscoped database operations. These concrete availability and security risks should be fixed or explicitly accepted before merging.

1040-1044: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Detection depends on the GetService<IRawSqlCommandBuilder>() call being inside the Build receiver.

IsLowLevelRawSqlBuild searches only the receiver expression of Build for a GetService<IRawSqlCommandBuilder> generic name. A two-statement form escapes detection:

var builder = db.GetService<IRawSqlCommandBuilder>();
var rawCommand = builder.Build(sql, [], db.Model);

The scanner then reports no occurrence, no execution violation, and no allow-list requirement, so the gate stays green for a new low-level raw command. The same gap applies to the non-generic GetService(typeof(IRawSqlCommandBuilder)) form. Consider also matching a Build receiver whose identifier is a local assigned from GetService<IRawSqlCommandBuilder>() in the same method, in the way ResolveSqlText already resolves a local SQL declaration.

268-275: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

The low-level raw-SQL path is not covered by the row-lock AccountId predicate walk.

The continue at Line 275 ends handling of the Build invocation, and the second pass at Lines 363-380 filters on the EF method names only, so Build is never predicate-walked. FindScopedUpdateArmViolations is internal and is called from tests only, not from Scan. A future low-level command that takes a row lock without an AccountId predicate therefore produces an occurrence, an allow-list entry, and a green gate.

Consider running HasRowLockKeyword / HasAccountIdPredicateInWhereClause on the resolved RawSqlText of this occurrence and adding any failure to rawSqlViolations, so the M4 rule applies to both raw-SQL layers.

Treat an unresolvable replacement as the end of the lineage. RevokeRefreshTokenAsync advances StepUpLogoutEpoch before RevokeExactLineageCoreAsync. A missing or owner-scope-mismatched child makes node null, and RunRevocationAsync rethrows the exception. AuthEndpoints.Logout then fails before clearing the cookie, so retries cannot recover while the durable pointer remains. InspectGraceReplacementAsync already treats retired-epoch children as inert. Log the condition and return when node is null.

EF Core 10 SqlQueryRaw scalar bool Value column data-modifying CTE support

💡 Result:

In EF Core 10, the SqlQueryRaw method is available for querying scalar, non-entity types [1][2][3]. When retrieving a scalar result such as a bool, you must ensure your SQL projects a single column named "Value" [4][5]. If you compose LINQ operators (e.g.,.Single,.FirstOrDefault,.ToListAsync) over your raw SQL query, EF Core treats your SQL as a subquery and appends its own logic [4][5]. Because it cannot inspect or rewrite your raw SQL, it expects the output column to be explicitly named "Value" to match the underlying mapping requirements [4][5]. For example: var result = context.Database.SqlQueryRaw("SELECT 1=1 AS "Value"").Single; Regarding Common Table Expressions (CTEs), EF Core does not have a specialized LINQ operator for CTEs, nor does it automatically translate LINQ queries into CTE-based SQL [6][7]. However, you can use CTEs in raw SQL queries executed via methods like FromSqlRaw or SqlQueryRaw [7][8]. Note the following critical distinction regarding CTE usage: 1. Data-Retrieving CTEs: You can use raw SQL containing CTEs (e.g., WITH cte AS (...) SELECT...) within SqlQueryRaw or FromSqlRaw to return data [7][8]. 2. Data-Modifying CTEs: If you need to perform data-modifying operations (e.g., WITH... UPDATE/DELETE/INSERT), you should use the Database.ExecuteSql or ExecuteSqlRaw methods, which are intended for non-querying SQL that does not return a result set [2][3]. Attempting to use a data-modifying statement within a method expecting a result set (like SqlQueryRaw) is generally unsupported and may cause runtime errors depending on the database provider's behavior.

🌐 Web query:

site:learn.microsoft.com/ef/core/querying/sql-queries SqlQueryRaw scalar Value composition subquery data modifying CTE

💡 Result:

Key points from Microsoft’s EF Core SQL-query documentation:

  • SqlQueryRaw<TResult> creates an IQueryable<TResult> for raw SQL returning scalar values or mapped types. It supports LINQ composition. (learn.microsoft.com)
  • When composing over a scalar SqlQuery/SqlQueryRaw, alias the projected column as Value, because EF Core wraps the SQL as a subquery and references that column externally:
    var ids = context.Database
        .SqlQueryRaw<int>("SELECT BlogId AS Value FROM Blogs")
        .Where(id => id > 10);
    (learn.microsoft.com)
  • Composition requires composable SQL—normally a SELECT. SQL containing a trailing semicolon, SQL Server query-level hints, or unsupported ORDER BY clauses cannot be composed as a subquery. (learn.microsoft.com)
  • Data-modifying SQL, including UPDATE, should use ExecuteSql/ExecuteSqlRaw, not SqlQueryRaw; these return the number of affected rows. (learn.microsoft.com)
  • Therefore, a data-modifying CTE cannot generally be passed to SqlQueryRaw and then composed with LINQ. Use ExecuteSql for the command, or expose a database function/view that returns rows for querying. This follows from SqlQueryRaw being a query API whose SQL is composed as a subquery, while ExecuteSql is the non-query API. (learn.microsoft.com)
  • Avoid interpolating untrusted values into SqlQueryRaw; use parameters or SqlQuery, which parameterizes interpolated values. (learn.microsoft.com)

🌐 Web query:

site:postgresql.org/docs data-modifying statements in WITH attached to top-level statement cannot be nested subquery

💡 Result:

In PostgreSQL, data-modifying statements (INSERT, UPDATE, DELETE, or MERGE) are only permitted within a WITH clause that is attached to the top-level statement [1][2][3]. They cannot be used within a WITH clause that is nested inside a subquery [1][2][3]. If you are using a data-modifying statement as part of a complex query, the WITH clause containing that statement must be placed at the beginning of the entire (top-level) command [1][2][3]. While this clause is attached to the top-level statement, the results of the data-modifying statement (typically via a RETURNING clause) remain visible and can be referenced by subqueries within the main statement due to standard WITH visibility rules [1][2][3]. For example, when performing an INSERT that includes a sub-SELECT, if you need to use a data-modifying statement, you must attach the WITH clause to the outer INSERT statement, not the inner sub-SELECT [1][2][3]. The inner sub-SELECT will then be able to reference the data-modifying CTEs defined at the top level [1][2][3].

Citations:


Replace the EF Core internals with a public command API that preserves top-level CTE execution.

IRawSqlCommandBuilder and RelationalCommandParameterObject are EF Core internal APIs. However, SqlQueryRaw<bool>(sql).SingleAsync(ct) is not a valid replacement: this SQL contains data-modifying UPDATE CTEs, and EF Core composes SingleAsync as a subquery. PostgreSQL permits data-modifying CTEs only in a top-level statement. Use a public ADO.NET/Npgsql command path and preserve the current connection, transaction, parameters, cancellation, and execution-strategy behavior. The "Value" alias does not resolve this limitation.

IsRawSqlCommandBuilderServiceResolution to also inspect preceding assignments to
the same in-scope local when its declaration has no initializer. Ensure builder
resolutions assigned after declaration receive the same bypass occurrence,
predicate validation, execution-seam validation, and allow-list handling as
initializer-based resolutions, and add a regression case for the
declaration-then-assignment shape.
- Around line 267-268: Update HasAccountIdPredicateInWhereClause to remove
single-quoted SQL literal contents before predicate matching, while retaining
quoted identifiers for valid AccountId references. Add a low-level-build
regression test covering a row-lock query whose only AccountId occurrences are
inside string literals, ensuring the gate rejects it.
