Closes #3310 Wires `ERROR_REASON.SDK_UNKNOWN_COMMAND` and `ERROR_REASON.USAGE` into the remaining untyped error paths in `gsd-tools.cjs` (template, frontmatter, requirements, milestone, uat, todo, workstream, graphify, learnings subcommand routers and `--cwd`/missing-required-arg paths). Tests assert via `JSON.parse(stderr).reason` rather than substring matching on prose. Closure regression guard locks the canonical `{ok, reason, message}` shape for every newly-typed path. Also moves `--json-errors` activation up to the top of `main()` so `--cwd` validation paths emit JSON rather than plain text when `GSD_JSON_ERRORS=1` is set.
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
node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD
Reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, deletes consumed fragments. Idempotent.
