Two outcome classesA worker exit returns no IPC result. Unicode truncation returns a damaged path that later fails correctly at realpath.

Route by the last boundary that worked.

A · no resultNode / Koffi crash

The dialog accepts a folder, then the worker aborts while materializing the path.

Node 22 ↔ Node 24+
B · wrong resultUTF-16 truncation

The worker returns a path cut immediately before a U+XX00 character.

开 U+5F00 → 00 5F
C · before dialogNative install

The native artifact never built inside the exact dependency tree DSH resolves.

install + import evidence
D · unhealthy ownerStale DSH process

An unexpected listener survives after its terminal or wrapper disappeared.

PID + parent + command line

rc.7 still carries the reported decode path.

The discussion reports the picker path succeeding on Node 22.23.2 and aborting on Node 24.18.1 across multiple Koffi versions. Treat that as a focused component A/B, not a claim that every Node 24 DSH feature is broken.

A zero byte is not a two-byte terminator.

rc.7 checks only the first byte, so it can return a shortened path and produce a downstream `ENOENT`. A regression fixture must contain an actual U+XX00 code point; “some CJK text” is not a sufficient test condition.

Recover through the shipped browse picker.

Prove the fallback.

  1. OpenIn-browser directory card renders.
  2. NavigateDrive root and nested paths resolve.
  3. UnicodeASCII and CJK paths round-trip exactly.
  4. U+XX00A path containing 开 round-trips exactly.
  5. CreateDisposable workspace is registered once.
  6. RestartWorkspace identity stays stable.

Primary evidence.
