Subject: [PATCH 01/47] Add SessionFs sqlite support for runtime sqlite routing

Update SDK to support the new sqlite() method on SessionFs, allowing
SDK apps to intercept per-session SQLite operations.

Key changes:
- SessionFsProvider.sqlite() accepts queryType parameter
- SessionFsSqliteQueryType exported from all entry points
- handleSqlite flag on SessionFsConfig
- Regenerated types for all language SDKs (Node, Python, Go, C#, Rust)
- E2E test for sqlite round-trip with queryType dispatch

Subject: [PATCH 02/47] SessionFs: make sqlite required, remove handleSqlite
 flag

sqlite is now a required method on SessionFsProvider. The handleSqlite
opt-in flag is removed from SessionFsConfig and the setProvider call.
Regenerated types for all languages from updated runtime schema.

Subject: [PATCH 07/47] .NET SDK: Add SessionFs SQLite support with
 ISessionFsSqliteProvider

- Add ISessionFsSqliteProvider interface for optional SQLite support
- Add SessionFsSqliteResult type for provider query results
- SessionFsProvider base class delegates to ISessionFsSqliteProvider at runtime
- Add Capabilities property to SessionFsConfig
- Client validates capabilities.sqlite matches ISessionFsSqliteProvider impl
- Regenerate Rpc.cs and SessionEvents.cs from updated schemas
- Fix pre-existing SwitchToAsync signature mismatch from codegen
- Add Microsoft.Data.Sqlite dependency for tests
- Add SessionFsSqliteE2ETests sharing Node SDK snapshots

Rows are now positional arrays aligned with the Columns list, avoiding
redundant dictionary key construction. The bridge code converts to keyed
dictionaries for the wire format. LastInsertRowid changed from double?
to long? since SQLite row IDs are always integers.

Subject: [PATCH 15/47] Fix CI: update existing tests to use sqlite provider
 interface

Existing sessionFs tests used the old flat sqliteQuery/sqliteExists
methods. Updated to use the new sqlite: { query, exists } interface
shape, and added ISessionFsSqliteProvider to ThrowingSessionFsProvider.

Subject: [PATCH 17/47] Add error handling to sqliteQuery/sqliteExists adapter
 methods

The sqliteQuery and sqliteExists adapter methods were throwing errors
directly instead of catching them and returning error results like all
other SessionFsHandler methods. This caused test failures when providers
threw exceptions that should have been caught and mapped to
SessionFsError.

Subject: [PATCH 19/47] Add SessionFs SQLite E2E tests for Python, Go, and Rust

- Add SessionFsCapabilities type and wire capabilities through
  setProvider RPC call in all three languages
- Create E2E test files with real in-memory SQLite implementations:
  - Python: test_session_fs_sqlite_e2e.py (using sqlite3 stdlib)
  - Go: session_fs_sqlite_e2e_test.go (using modernc.org/sqlite)
  - Rust: session_fs_sqlite.rs (using rusqlite with bundled feature)

Subject: [PATCH 20/47] Fix CI: formatting, Go race, Node sqlite error
 handling, scenario go.mod

- Fix Python/Rust formatting issues caught by CI linters
- Fix Go data race in SqliteQuery by holding mutex for full operation
- Add try/catch to Node.js sessionFsProvider sqlite methods for error mapping
- Update Go scenario go.mod files from go 1.24 to go 1.24.0

Subject: [PATCH 22/47] Fix Go and Rust CI: remove unused func, fix clippy
 warnings

- Go: remove unused getOrCreateDB() wrapper (only getOrCreateDBLocked used)
- Rust: collapse nested if-let chains using .filter() (clippy::collapsible_if)
- Rust: scope MutexGuard in blocks to avoid holding across await (clippy::await_holding_lock)

Subject: [PATCH 24/47] Fix Go SQLite E2E: force single connection for
 in-memory DB

Go's sql.DB is a connection pool. With :memory:, each connection gets
its own separate in-memory database, so INSERT on one connection is
invisible to SELECT on another. SetMaxOpenConns(1) forces all queries
to share the same in-memory database.

Subject: [PATCH 26/47] Replace real SQLite with stub in Go E2E tests, revert
 go.mod changes

Remove modernc.org/sqlite dependency from go/go.mod and revert the go
directive back to 'go 1.24' (matching main). This also reverts 31
scenario go.mod files that were forced to 'go 1.24.0' by the transitive
dependency.

The Go E2E test now uses a stub SQLite handler that returns canned
responses matching the CAPI replay snapshots, rather than executing real
SQL. This tests the same SDK wiring (RPC routing, call capture,
assertions) without pulling in a heavy native dependency.

From d853a4d080ca23c9e38a41bc59cc6ee76450cb5d Mon Sep 17 00:00:00 2001
From: Steve Sanderson <SteveSandersonMS@users.noreply.github.com>
Date: Tue, 19 May 2026 13:34:39 +0100
Subject: [PATCH 27/47] Rust SQLite E2E: use stub responses instead of real
 rusqlite

Replace real rusqlite dependency with canned stub responses in the Rust
SQLite E2E test. The CAPI replay snapshots contain pre-recorded tool
results, so the test only needs to return matching canned data.

This fixes the Windows-only failure where rusqlite in-memory database
SELECT returned 0 rows despite successful INSERT. Also removes the
rusqlite dev-dependency (which compiled bundled C code, slowing CI).

Subject: [PATCH 28/47] .NET SQLite E2E: use stub responses instead of real
 Microsoft.Data.Sqlite

Same approach as Go and Rust E2E tests - return canned responses
instead of running real SQL, avoiding Windows-only in-memory SQLite
failures. Removes Microsoft.Data.Sqlite dependency from test project.

Subject: [PATCH 29/47] Restore real SQLite in .NET and Rust E2E tests, fix Go
 stub comments

Revert .NET and Rust E2E tests back to using real SQLite (Microsoft.Data.Sqlite
and rusqlite respectively). Only Go uses stub responses to avoid the modernc.org
go directive cascade.

Also fix misleading comments in Go SQLite stub that incorrectly attributed stub
correctness to CAPI replay snapshot content.

Subject: [PATCH 30/47] Make SessionFs SQLite optional in Go, Python, and Rust

Split SessionFsProvider into base (FS-only) and SessionFsSqliteProvider
(SQLite) in Go, Python, and Rust to match the Node.js/C# design where
SQLite support is opt-in rather than required on all providers.

Go: Separate SessionFsSqliteProvider interface with type assertion dispatch.
Python: Separate SessionFsSqliteProvider ABC with isinstance check.
Rust: Separate SessionFsSqliteProvider trait with fn sqlite() accessor.

All three languages validate capabilities.sqlite at session creation/resume
and return result-level errors (not transport errors) when SQLite is
unsupported.

Subject: [PATCH 32/47] Remove sqlite methods from non-sqlite Rust E2E test
 provider

The TestSessionFsProvider in session_fs.rs should not implement sqlite
methods since these tests cover FS-only operations. SQLite coverage is
in session_fs_sqlite.rs.

Subject: [PATCH 34/47] Align Go/Python/Rust SQLite provider APIs with
 Node.js/.NET design

- Remove session_id parameter from sqlite_query/sqlite_exists (providers
  are already session-scoped)
- Add clean SessionFsSqliteQueryResult types without error field (errors
  signaled by raising/returning errors, not via result field)
- Update adapters to convert clean result types to generated RPC types
- Update all tests to use new signatures and clean result types

Subject: [PATCH 35/47] Reorder sqlite_query params: query_type before query
 (match Node.js/.NET)

All SDKs now use (queryType, query, params) parameter order, consistent
with the Node.js and .NET reference implementations.

 remove stale type: ignore comments

- Rename 'provider' to 'fs_provider' in client.py create/resume to avoid
  shadowing ProviderConfig typed variable
- Import SessionFsProvider in client.py for proper type annotation
- Remove 11 unused '# type: ignore[attr-defined]' comments in adapter

Subject: [PATCH 38/47] Fix E2E sqlite test session_id recording and Windows
 flaky test

Go/Python/Rust: Fix E2E stub providers to record actual session ID
from stored state instead of hardcoded strings, so filterCalls
assertions match the real session.

Node.js: Move SQLite database Map to describe scope so it survives
handler re-creation. The factory-scoped closure variable caused each
handler invocation to create a fresh :memory: database, losing
previously inserted data. This caused intermittent failures on
Windows where the CLI re-creates the handler between tool calls.

Subject: [PATCH 39/47] Align .NET sqlite provider Rows type with wire format

Change SessionFsSqliteResult.Rows from IList<object?[]> (positional
arrays) to IList<IDictionary<string, object>> (keyed dictionaries),
matching the generated wire type exactly. This eliminates the
positional-to-keyed conversion in the adapter.

Subject: [PATCH 44/47] Address PR feedback: integer LastInsertRowid, optional
 query return, unused var fixes

- Change LastInsertRowid from float to integer type in Python (int|None),
  Go (*int64), and Rust (Option<i64>). Adapters convert to wire float types.
- Make sqlite_query return optional in Python (| None) and Rust (Option<>),
  matching Node.js and .NET behavior for exec-type queries.
- Fix unused msg variable in Python E2E test.
- Remove unused import in Rust E2E test.
