TURBOREPO HARDENS AGAINST OS-LEVEL CRASHES AND BAKE LOCKFILE BREAKAGE

Turborepo shipped four critical fixes overnight that prevent panics on non-UTF-8 paths, stop Bun lockfiles from rewrites, and close a symlink race condition in logging.

The most urgent: Rust panics when encountering non-UTF-8 bytes in environment variables or filesystem paths can now crash the daemon [1]. Turborepo now defers those panics until a package actually needs to process the bad path, and keeps OS-native representations instead of forcing UTF-8 conversion at the boundary. The same hardening applies to SCM parsing [2], where valid Unix Git paths containing non-UTF-8 bytes were breaking unrelated package hashes. That fix now preserves raw Git paths and only errors if a queried package actually includes one. Separately, Bun's duplicate alias requirement was causing `turbo prune --docker` to emit lockfiles Bun treated as stale, triggering rewrites even under `--frozen-lockfile` [3]. Structured log creation also had a TOCTOU window where symlinks could slip through validation before the file opened [4]. All four fixes are already in canary and stable. Finally, Turborepo now denies Clippy's unwrap/expect usage by default across the workspace [5], with gradual cleanup in progress. Next.js 16.3.0-canary.22 ships the turbo-tasks recomputation priority bump [6] that schedules cache misses ahead of invalidation work.
