 ### Bug Fixes
 
@@ -299,6 +302,8 @@ Z3 SMT solver bindings as a dynamic module, dasLLVM-style.
 - **Nine red-first fixes from the doc-probe triage** (#3662) - `operator []<-` dispatch, `require X as Y` alias registration for all forms, false `[nodiscard]` errors in string interpolation, the `each_ref` crash, transactional qmatch captures, linq `_fold` defer, SQL generated-column visibility, and the temp-string AOT hash desync (162 `error[50101]` -> 0)
 - **`float2(x) * y` folded to `(x*y, 0)`** (#3776) - the splat-collapse rule installed a scalar operator under a vector-typed node, and its operand swap could reorder observable effects; both arms now require the other operand to be the vector and decline impure operands - one AST-level fix covers interpreter, JIT, and AOT (v0.6.4-RC1 only)
 - **The RC1 `-exe` toolchain could not run from a bundle** (#3779, #3781) - the prebuilt tools' rpath missed the installed `lib/` on Linux/macOS; the module native-path table carried the build machine's absolute paths, now re-rooted at run time (exe-relative, then das-root, then baked); and `dastest.exe` demanded a JIT it does not link - it runs the interpreter, the `-jit` host is unchanged. The bundle smoke now launches every shipped tool instead of presence-checking it
+- **Browser audio corrupted on Windows** (#4045) - the mixer's producer slept 1 ms when its 10.7 ms ring was full, and a sleep resolves to the host's timer quantum: ~1 ms on macOS, 15.6 ms on Windows (measured in a Worker at 16.0 ms median, 16.6 ms worst), so the ring emptied every cycle there while the same build played clean on a Mac. It parks on a drain counter now; `modules/dasAudio/REVIEW.md` bans a sleep-timed producer and a ring deepened to hide underruns. In the same change a zero spin window parked one iteration late after a served team chunk, and `standalone_capi_dasbind` could never pass under a multi-config generator (the fixture DLL landed in `Release/` while the generated bindings looked one level up)
+- **`test_worker_heap.das` flaked at 10.002 MB against a 10 MB bar** (#4047) - the number the strudel worker publishes is its heap BEFORE the tick's collect, so it jitters by one tick's garbage (up to ~10 MB on a cycle-boundary tick, 9.7 MB of spread on an idle 64-core box) and a `peak - base` bar measured that burstiness, not collection - widened 2 -> 5 -> 10 MB chasing it. The test now asserts what only a collect produces - a published number lower than the one before it, and a floor that holds across two stretches - on the worker's own clock

 - **The release audit** (#3773, #3782) - `utils/internal/test-release`: the compile phase proves every shipped example and tutorial against the bundle's own binary (803 targets), and the utils phase exercises every shipped tool from the extracted bundle alone (exit code plus output only a working run prints). The RC1 sweep's structural yield: `examples/` and `tutorials/` install as whole directories, so 31 silently-dropped files ship again; three ship-defects fixed; package examples moved to their package repos
 - **A hung sweep names the program that hung** (#3949) - dastest prints a timestamped `run N/M: <file>` before every program of a sequential sweep and `worker K starts: <files>` before every isolated batch, on stderr, flushed at once and printed under `--failures-only` too; the `run_tests_*` cmake targets carry `USES_TERMINAL`, so Ninja streams the sweep's output instead of holding it until the command ends - a lane cancelled mid-hang keeps its last line instead of losing everything the sweep printed. The first hang those lines named was `tests/debug_agent/test_callback_threadlock.das`: its hook waited on a thread that had yet to create its context, while the tick holds the agent registry every context creation needs - `DapiDebugAgent` carries the contract, and the test now proves the callback/pinvoke serialization from one thread with the new `try_invoke_in_context`, the non-blocking `invoke_in_context` that returns false, running nothing, while another thread holds the context lock
 - **Bounded apt on ubuntu runners** (#3785) - every workflow apt site goes through `ci/apt_install.sh`: the degrading Azure mirror swapped for the public archive (mirrorlist included), capped fetches, retried update - the worst case becomes a loud failure in minutes instead of a silent hours-long hang
+- **Gate rosters catch up with the tree** (#4047) - `MESHOPTIMIZER.LICENSE` joins the bundle smoke's license roster (the module is default-on and its MIT notice installed, but the gate that exists to notice a silently-skipped install rule did not list it); preflight's compile sweep stops trying `examples/dasLLAMA/library/main.das`, whose `dasllama_lib_c` only the opt-in `dasllama_lib_jit` target writes (#4045); `tests-cpp`'s `standalone_ctx` fixture pins its output directory with `$<1:...>` so `standalone_capi_dasbind` passes under Visual Studio and Xcode generators (#4045)
