A tiny rule to steer the night.
Picomatch bound to versions new,
I tuck a version hint in view. 🐇✨

Consider the version pinning strategy for security dependencies.

This dependency uses an exact version pin (2.3.2) while most other dependencies use caret ranges (^). If 2.3.2 is confirmed as the patched version for CVE-2026-33671, consider whether:

1. Exact pinning is appropriate to prevent regression to vulnerable versions, OR
2. A caret range (e.g., ^2.3.2) would be better to allow future patch updates while staying within the safe major version

The approach depends on the picomatch versioning scheme and where the vulnerability was introduced.

- Line 80: The lockfile still resolves picomatch@4.0.3 even though package.json
pins "picomatch": "2.3.2", so the CVE remediation is incomplete; update the
transitive resolution by adding a pnpm override/resolution for picomatch (force
4.0.4 and/or 3.0.2), or run a full lockfile refresh so pnpm-lock.yaml no longer
contains picomatch@4.0.3: add an "overrides" (pnpm) or "resolutions" (if using
yarn) entry in package.json targeting picomatch, run pnpm install to regenerate
pnpm-lock.yaml, verify no picomatch@4.0.3 remains (search lockfile), and commit
the updated pnpm-lock.yaml along with package.json.

✅ Changes Applied

I've updated the code based on your feedback:

The code review flagged that picomatch: "2.3.2" uses an exact version pin, inconsistent with the rest of the project's dependencies which use caret ranges (e.g., ^). Changing it to "^2.3.2" ensures the CVE-patched minimum version is enforced while allowing future compatible patch/minor updates, matching the project's conventions. The pnpm-lock.yaml specifier field is updated to match.

Requesting changes because this only partially remediates the picomatch CVE.

I checked the branch lockfile and ran pnpm audit --audit-level low --json: picomatch@2.3.1 is gone, but vulnerable picomatch@4.0.3 remains via @vitest/ui > tinyglobby > picomatch, so CVE-2026-33671 still reports against this PR. Also, OpenSpec does not import picomatch directly, so adding it as a new runtime dependency looks like the wrong shape.

Please update/override the transitive dependencies so the lockfile has no vulnerable picomatch lines left, especially no picomatch@4.0.3, then re-run audit. A lockfile refresh or focused pnpm override is cleaner than an unused direct dependency.

Removing the incorrectly added direct picomatch dependency from package.json while keeping the pnpm override. OpenSpec doesn't import picomatch directly, so it should only be managed as a transitive dependency via the pnpm.overrides section. The override "picomatch": ">=4.0.4" will force all transitive dependencies (including @vitest/ui > tinyglobby > picomatch) to use the patched version 4.0.4 or higher, fully remediating CVE-2026-33671.

Requesting changes again: the lockfile has the picomatch: >=4.0.4 override, but package.json now has an empty pnpm.overrides object, so pnpm install --frozen-lockfile fails with ERR_PNPM_LOCKFILE_CONFIG_MISMATCH.

Please put the picomatch override back in package.json, regenerate the lockfile, and keep the two files aligned.

The override "picomatch": ">=4.0.4" is too permissive in the wrong direction — it jumps all consumers (including those targeting the v2 or v3 API) onto v4+, which can introduce breaking changes. The CVE advisory confirms three separate patched versions (2.3.2, 3.0.2, 4.0.4), one for each major release line. The correct override is ^2.3.2 || ^3.0.2 || ^4.0.4, which pins each consumer to the closest patched version within its compatible major version range.

Additionally, pnpm-lock.yaml had the actual fdir peer dependency metadata (^3 || ^4) incorrectly replaced with the override constraint (>=4.0.4). Those lines reflect what the upstream package declared and must be restored to their registry values.

[alfred-openspec]

The security remediation is now doing the right thing: package.json and pnpm-lock.yaml agree on the picomatch override, pnpm install --frozen-lockfile passes, pnpm why picomatch resolves only picomatch@4.0.4, and pnpm audit --audit-level low no longer reports a picomatch advisory.

One small blocker remains before merge: this PR now commits an empty pnpm-lock.yaml.tmp file. Please remove that stray temp file from the branch, then this should be good to merge from my side.

The only remaining blocker identified by @alfred-openspec is the stray empty pnpm-lock.yaml.tmp file that was accidentally committed to the branch. All other security remediation (the pnpm.overrides in package.json and the updated pnpm-lock.yaml) is already correct and approved. I just need to delete the pnpm-lock.yaml.tmp file.

Re-reviewed the latest head. The package/lockfile mismatch is fixed, pnpm install --frozen-lockfile succeeds, pnpm why picomatch resolves to only picomatch@4.0.4, there is no direct picomatch dependency, and the full test suite passes.

pnpm audit still exits non-zero because of unrelated existing advisories, but I do not see a remaining picomatch advisory in the audit output.
