The project-owned symlink exception applied to every direct child, so openspec/changes/archive could point outside the root and archive succeeded. Limit that exception to the changes and specs directories.

The archive symlink exception treated every direct child as a project-owned link. c1c9d0c limits the exception to the changes and specs directories themselves. Docker |

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Add required Windows-separator coverage.
test/core/archive.test.ts:623 skips this path test on Windows. The changed archive containment guard uses path.sep, so the test guidance requires coverage that exercises the native separator. Without it, a Unix-only regression can pass the test suite.

Thanks for digging into #2050 — and for spotting that the containment guard was the thing in the way. I reviewed this against #2052, which fixes the same issue, and I'm recommending we land #2052 instead. Two reasons, both of which I reproduced locally rather than read off the diff. 1. It doesn't fix #2050 for a change that carries spec deltasWith The same layout with The cause is at 2. The relaxation isn't bounded the way the description saysThe body says it accepts "a direct child directory that is a project-owned symlink … without weakening canonical checks for nested paths." In the code at const projectOwnedDirectory =
managedDir === changesDir || managedDir === mainSpecsDir;
The Credit where it's due — the second commit does close the escaping- A question for the maintainers that outlives this PRBoth this and #2052 let Worth noting the codebase already treats this exact silence as the defect one level down, at
and emits Closing in favor of #2052 — but the diagnosis here was right, and the escaping- 🤖 Generated with Claude Code |
Fixes #2050. Allows archive's root-containment guard to accept a direct child directory that is a project-owned symlink (e.g. openspec/changes -> shared docs repo), without weakening canonical checks for nested paths. Build and archive tests passed.
