* test(#3900): a unix socket under the repo root must not break the overlay (failing first) * fix(#3900): the overlay walker skips non-regular files (sockets, FIFOs, device nodes) The walker classified every not-a-directory entry as a file, so a unix socket anywhere under the repo root (an MCP server, a language-server daemon, a watcher) made copyFileSync throw ENXIO — the reporter measured 32 local test failures across 6 files, all in before() hooks, none about the code under test; a FIFO would block until a writer appeared. The hard-link path does not save it: the overlay sits under tmpfs, so cross-device EXDEV always falls through to the copy. One guard at the classification site (srcStat.isFile() before the copy/link branches) — sockets, FIFOs, and device nodes are not repository content; CI never saw this because a fresh clone has no working-tree daemons, which is exactly why it ate local debugging time. Also adds opts.root (test-only root override, default REPO_ROOT) so the regression tests build the overlay from a tiny synthetic root in milliseconds instead of paying a full repo walk. * chore(#3900): changeset fragment (pr number backfilled after PR creation) * fix(#3900): review fold-ins — sibling cold-fixture guard, changeset format, root doc buildColdInstallTree enumerated the live repo's hooks/ with a NAME-only filter — the same class #3900 documents: a daemon socket or FIFO inside hooks/ would reach cpSync and throw ENXIO (or block). Dirent type guard added. The changeset gains the mandated bold user-visible lead, and opts.root is documented at its definition (mirroring cold-runtime-lib- fixture's repoRoot convention). * chore(#3900): backfill changeset PR number (4062) --------- Co-authored-by: sim <sim@local>
Changeset Fragments
This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.
Why
Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.
See #2975 for the full rationale.
Adding a fragment
node scripts/changeset/new.cjs \
--type Fixed \
--pr 1234 \
--body "fix the thing — explain the user-visible change in one sentence"
This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.
Format

type: Fixed
pr: 1234

**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.
Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.
Opting out
PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.
At release time
Promotion is automatic. The release workflow's finalize job runs:
node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty
This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.
Archived fragments
.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
