Closes #2050.

What this changes

openspec archive refused to run when openspec/changes or openspec/specs is a symlink to a directory in another repository, failing with "Refusing to archive through a path outside the OpenSpec root". The containment check now accepts those two directories being project-owned symlinks, and delta verification also follows a symlinked changes directory. Paths that escape through anything else are still refused.

How you verified it

New tests in test/core/archive.test.ts fail on the base commit (4 failed, 267 passed) and pass on this branch (271 passed, 0 failed). I did not run pnpm build, tsc or pnpm lint.

Notes

Written by Claude Code (Claude Sonnet 5.5); I ran the archive tests above and checked the result.


  • Ran pnpm changeset if this affects users, and committed the file
  • If a coding agent wrote this, named the agent and model in the Notes section, and verified the result myself

Summary by CodeRabbit

  • Bug Fixes
    • openspec archive now supports symlinked openspec/, openspec/changes, and openspec/specs directories, including when the entire openspec/ directory points elsewhere.
    • Changes can be archived and their spec updates applied through these symlinked directories, including when the archive operation uses a cross-device fallback.
    • An archive/ directory that resolves outside the changes directory is still rejected, and the change is left untouched.

…mlinks

archive refused a changes or specs directory that is a symlink resolving
outside the project root. Allow such a link when its parent is inside the
root and it resolves to an existing path, and still require archive/ to
stay within the changes directory.

Fixes Fission-AI#2050
…ctory

verifyArchivedDeltas measured the canonical delta source path from the
non-canonical change directory, so with openspec/changes symlinked it
looked for the archived delta at a wrong relative path and failed the
final-move check. Measure from the canonical change directory captured
before the move. Add tests that archive a spec delta with changes, specs,
and both symlinked.

📝 Walkthrough

Walkthrough

The archive command now accepts project-owned symlinks for openspec/, openspec/changes, and openspec/specs. It keeps archive/ within the changes directory and calculates archived delta paths relative to the canonical change directory.

Changes

Archive symlink support

Layer / File(s) Summary
Linked path validation
src/utils/file-system.ts, src/core/archive.ts, test/core/archive.test.ts, .changeset/archive-symlinked-changes-dir.md
A new filesystem check permits an existing linked leaf when its parent is confined. Archive validation applies it to openspec/, changes/, and specs/. Tests cover these linked directories and reject an archive/ symlink that escapes the changes directory. The changeset records the behavior.
Canonical delta paths and fallback
src/core/archive.ts, test/core/archive.test.ts
Final archive verification and fallback-copy delta paths use the canonical change directory. A test covers the cross-device fallback through a symlinked changes directory.

Full details: Out of Scope Changes check

Explanation

The implementation also permits openspec/ itself to be a symlink and adds a test and changeset claim for that behavior. Issue #2050 and the current PR objective limit the requested support to openspec/changes and openspec/specs; they state that paths escaping through anything else remain refused. Whole-openspec symlink support is not required for that objective.

Exercise the linked-directory path on Windows.

Both new test groups return on win32. Use directory junctions on Windows and run at least one delta-archive case there. This will cover the changed path.relative calculation with Windows path separators. As per coding guidelines: “When touching path behavior, add coverage that would fail on Windows path separators.”

Also applies to: 655-655

Every other command already works when the whole openspec/ directory is
a project-owned symlink, but archive still refused it: changes/ was
checked against the project root, and changes/ itself is not a link in
that layout. Check each level against its parent instead, so openspec/,
changes/ and specs/ may each be a link while archive/ must still stay
inside changes/.

Tests now use junctions on Windows instead of skipping it, and cover an
archive/ that escapes a linked changes/ and the cross-device move
fallback through a linked changes/.
