0.9.2 — 2026-05-18

Release Notes

Linux-enablement patch release. With 0.9.1 a fresh Linux install would
postinstall correctly but then fail two ways: loom doctor reported
chromium binary not found (#70), and every web.* action surfaced as
surface_trap because the shim's IPC socket raced Tokio's I/O driver on
fd 3 (#71). 0.9.2 fixes both — loom serve + loom action web.navigate
now drives headless Chromium end-to-end on Linux without a system Chrome
on $PATH.

Fixed

• loom doctor + loom session Chromium detection on Linux/Windows
  (#70). loom doctor's chromium_present_and_verified check and the
  chromium_resolver launch path both hardcoded the macOS .app bundle
  layout (Chromium.app/Contents/MacOS/Chromium) regardless of host OS,
  while loom postinstall correctly extracted the pinned Chromium to the
  per-OS path (chrome-linux/chrome on Linux). Net effect on Linux:
  loom doctor reported chromium binary not found and the launcher
  could not find loom's own pinned download — it only worked when a
  system Chromium happened to be on $PATH. The per-OS layout is now a
  single shared source of truth,
  loom_shared::chromium_resolver::chromium_binary_subpath(), consulted by
  postinstall, doctor, and the resolver alike.

• Shim IPC fd collision with Tokio I/O driver on Linux (#71).
  spawn_shim dup2'd the IPC socketpair end onto fd 3, but
  loom-shim-chromium's Tokio multi-thread runtime claims the lowest
  free descriptors at startup for its epoll instance + wakeup eventfd.
  Adopting fd 3 as the IPC socket then races the I/O driver:
  UnixStream::from_std returns EINVAL, the driver panics with
  Bad file descriptor, the shim exits, and every web.* action
  surfaces as surface_trap. The IPC socket is now pinned to fd 10 via
  a named SHIM_IPC_FD constant — well clear of the runtime's low-fd
  range. loom-shims/tests/binary_smoke.rs updated in lockstep.
