tesla-http-proxy could exit 0 and print nothing when it failed to start, so supervisors keyed on exit status (Docker / systemd on-failure, shell &&) treated a failed launch as a clean one.

Split startup into small error-returning functions and made main a thin boundary that writes "Error: <reason>" to stderr and exits 1 regardless of log level.

Merged into Tesla's official Vehicle Command SDK by a Tesla maintainer — failed starts are now observable to process supervisors.

In Nav2's BtActionNode, halting during the window after a goal is sent but before the action server returns the goal handle could leave the in-flight goal uncancelled — an action-lifecycle race.

Handled the halt-before-acknowledgement case so the goal is cancelled correctly once the handle arrives, with a regression test in test_bt_action_node.cpp.

Merged into main by Nav2's lead maintainer, Steve Macenski, and closes issue #6426 — a reliability fix in the flagship ROS 2 navigation stack.

When a missing attribute appeared in a narrowing condition, Pyrefly cached `object` instead of the error-origin `Unknown` from ordinary lookup, so later indexing produced a cascade of false errors.

Recover missing lookup members as `Unknown` — preserving valid union members, positive refinement and genuine type errors — and treat reads of an error-`Unknown` as propagation to avoid duplicate diagnostics.

In PDQ's C++ downscaling, row-major offsets and box-filter accumulators are `int`; for images where rows×cols exceeds INT_MAX this is signed-overflow UB, reachable from the public pdqHash256FromFloatLuma entry point and causing out-of-bounds access.

Widened the offset and accumulator arithmetic to prevent the overflow and resulting OOB access, with a dedicated downscaling test.

Mariana Trench missed taint flowing through static fields: a static write and a later read didn't share a storage location, so tainted values never reached the sink — a false negative.

Added a StaticFieldMemoryLocation, stored static writes there, and resolved references through different declaring types to the same static field so taint is retained across the write.

On macOS, AppKit services UI objects only on the main thread, but MuJoCo Studio's native launcher ran the viewer on a daemon worker thread — so the window was never created and the viewer failed to start.

Added platform-aware launching that runs the viewer on the main thread on macOS while leaving Linux and Windows behaviour unchanged.

The WOSAC notebook decoded each scenario ID into a variable-length tensor before dense batching, so differing ID lengths failed in TensorFlow while equal-length IDs were silently concatenated.

Kept IDs as strings until NumPy conversion, decoded each ID separately outside JAX, and compiled only the numeric simulator conversion — preserving the Python-string interface.

make_sdc_dm_environment built configured IDM actors but omitted their parameter entries, so PlanningAgentEnvironment rejected any nonempty actor configuration before reset.

Passed one None slot per parameter-free actor, preserving the factory API and constructor check, with regression coverage for batching, reset/step and invalid controls.

RolloutCarry.observation's docstring said it was the actor's model input, but rollout() hands the actor the full simulator state — never that field — confusing users (reported in #73).

Documented the actual intended design and added a regression test; no runtime behaviour changes.

Re-enabling showFrame on an already laid-out Android camera produced a 53×53px corner fragment because the overlay's measured dimensions were still zero.

Computed frameRect from actual layout bounds in onSizeChanged() and used them when resizing the custom frame, with four Robolectric regression tests.

The servo_keyboard_input demo could read freed memory because its ROS spin thread outlived the resources it referenced.

Join the spin thread on shutdown so it stops accessing freed memory — a clean lifetime fix for the demo.

When an edge function was removed from config.toml on a preview branch, Studio's Edge Functions merge tab showed "No changes detected", hiding the deletion so the function looked still-deployed.

Fixed useEdgeFunctionsDiff so removed or disabled functions surface as a deletion diff on the merge page, with a regression test.
