Summary

  • Pins Bun 1.4.3 (latest, 2026-10-10) in test.yml, lint.yml and release.yml (setup-bun and the compile matrix's BUN_VERSION), replacing 1.3.11.
  • Why: on feat: add reproducible workspace file staging #22's branch the test + pack job dies at the end of the run with Bun's own crash report ("panic(main thread): Segmentation fault at address 0xAAE2AA80 … Bun has crashed. This indicates a bug in Bun, not your code", exit 132). Same address on Oct 15 and Oct 16, while main passes on 1.3.11 and the branch passes on macOS and with Docker enabled. 1.4.x carries the memory/crash fixes since 1.3.
  • Verified locally under Bun 1.4.3: bun install --frozen-lockfile accepts the existing lockfile; typecheck, lint and the full suite are unchanged (the one offline failure is the known Docker-absence case in tests/mcp-proxy.test.ts).
  • Not changed: images/egress-proxy and images/mcp-proxy still build FROM oven/bun:1.3-slim; bumping those changes shipped image content and belongs in its own change.

Bun 1.3.11 segfaults at the end of the test run on the PR #22 branch
("panic(main thread): Segmentation fault", Illegal instruction, exit 132,
same address on two runs a day apart) while the same code passes on
macOS and the suite on main passes in CI. 1.4.x carries the memory and
crash fixes since 1.3; the lockfile installs frozen under 1.4.3 and the
suite is unchanged under it locally.
