Replace ad-hoc AIO with structured concurrency (TVar + async registry); builder returns results directly; remove lazy splitIO/unsafePerformIO - Reduce redundant thread creation; use per-key builderOne and STM retry instead of spawning; fewer races - Add AsyncParentKill (ThreadId, Step) and treat it as async; use cancelWith from Shake to scope cancellation to the current session - Mask critical sections and do uninterruptible cleanup on exception (mark Dirty) to avoid stuck Running and hangs -

Introduce DirectKey and newDirectKey for internal/ephemeral action keys - Export pattern DirectKey from graph and types modules - Update fromKey/fromKeyType to return Nothing for DirectKey - Render and Show support for DirectKey - Ensure rule machinery rejects DirectKey (no associated rules) - addRule/runRule now error on DirectKey - Use DirectKey for DeliverStatus in pumpActionThread - Avoids using the “root” key and enables per-action identity - Make shakeRunDatabaseForKeysSep test-aware and filter reenqueued work - Add Bool isTesting parameter (propagated from ghcide newSession) - When not testing, filter reenqueued items that are preserved/unaffected - Preservation API changes - incDatabase/incDatabase1 now return a KeySet of preserved work - computeToPreserve returns (unaffected, preservedSet) and uses deliver keys - Refactor runtime deps mapping - Rename databaseRuntimeDep -> databaseRuntimeDepRoot - Track reverse deps as before; additionally record deps under root DirectKey parents - Update insert/delete helpers and add isRootKey predicate - Action queue utility -
