Conversation
Stop verified project daemons and confirm termination before recreating SQLite. Fence daemon and proxy reopening throughout rebuilds while preserving foreign and newer locks. Add Windows lifecycle coverage and cross-platform shutdown regressions. Co-authored-by: Harry B ✦ <drewavesx0@gmail.com> Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Carry the #1325 rebuild fence through the upstream explicit-project lifecycle, read-only engine opens, synchronous initialization retries, and direct writer acquisition. Preserve shared project leases, read-only fallback behavior, freshness handling, and direct-mode query pools. Cover watched, unwatched, and read-only engines blocking during a foreign rebuild and recovering after the fence is released.
#1325) A projectPath call during `codegraph index` hit assertNoRebuild's plain Error and returned isError; it is an expected, temporary condition, so it now uses a RebuildInProgressError that the tool handler answers success-shaped. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Problem
On Windows, an MCP daemon surviving client shutdown retained SQLite handles, causing
codegraph indexto fail with EPERM.Fix
Build on @hbui290's #1375 with current identity safeguards, confirmed termination, and rebuild ownership that prevents daemon/proxy reopening. Preserve foreign and replacement locks and report failed shutdown accurately.
Validation
npx tsc --noEmitpassed on Windows and macOS.Fixes #1325
