 8. **Index shared with Xcode works:** with Xcode's DerivedData layout (index store = `Index.noindex/DataStore`, `INDEX_REGULAR_BUILD_*` = `Build/…`), units written by an xcodebuild build count as up to date: after building `macOS Browser`, indexing skipped all app files (2,150 files left vs 3,972). BSP prepares in `Index.noindex/SourceKitBuild` so it never shares a build DB with an open Xcode.
 9. **Xcode-compatible builds:** `xcodebuild` without `-derivedDataPath` and the wrapper don't rebuild after each other (no-op 26–31 s). With `-derivedDataPath` pointing to the same folder they do.
 10. **iOS simulator:** generic destination fails (`fix_libswiftWebkit_simulator.sh` needs `TARGET_DEVICE_OS_VERSION`) → build for a concrete simulator. Debugging: `simctl launch --wait-for-debugger` + lldb-dap attach by **pid** works (breakpoint in `AppDelegate`). lldb-dap with `attachCommands` or with `program` + pid never stops at breakpoints (CLI lldb does) → launch config uses `${command:pickProcess}` (newest first). VS Code substitutes variables before `preLaunchTask`, so run the task first.
+10a. **Gray breakpoints in VS Code (macOS app):** the launch configs had `sourceMap` `/^wt → worktree` for all builds. lldb also applies it in reverse when setting breakpoints, so `<worktree>/…/File.swift` became `/^wt/…/File.swift`, which regular (Xcode-mode) debug info doesn't contain → "no locations". Fix: no `sourceMap`; `xcodebuild.sh` writes `.build/debug.lldbinit` per build (source map only for `DDG_WORKTREE_CACHE=1`), launch configs `command source` it in `initCommands`. Confirmed fixed in VS Code 2026-10-15.
 11. Index sharing between worktrees: rejected (absolute paths + mtime-based staleness).
 12. `workspace/_pollIndex` isn't in release sourcekit-lsp → indexer waits for "Indexing" progress end + 60 s quiet; gives up after 5 min without progress.
 13. swift-build service runs in its own process group → stop children first.
