* fix(#2395): persist runtime identity into ~/.gsd/defaults.json for non-Claude installs Bug: finishInstall for non-Claude runtimes never persisted a 'runtime' key into ~/.gsd/defaults.json. resolveRuntime() precedence is GSD_RUNTIME env > config.runtime > 'claude', so both inputs being empty on a Cursor (or any non-Claude) install caused agent_runtime and every runtime-branded slash hint to silently fall through to 'claude'. Cursor users saw 'agent_runtime: "claude"' and Claude-formatted /gsd-* hints with no env or config hand-set. Fix mirrors the existing resolve_model_ids: 'omit' write site at the same call site (bin/install.js finishInstall, gated on !_hostBehaviors(runtime) .nativeModelAliases && !GSD_TEST_MODE). Writes runtime: <runtime> into ~/.gsd/defaults.json when absent/null/empty. Claude is the resolveRuntime() fallback so it needs no write; an explicit pre-existing runtime value is always preserved across installs of any runtime. Pattern parity with #1156 (default-to-omit intent) and #1569 (preserve explicit user value) — the new write is the third sibling on the same install-time persistence block. Regression tests in tests/install.test.cjs cover: - absent / null / empty-string runtime → populated to <install runtime> - explicit pre-existing runtime preserved (no clobber across runtimes) - parameterized across 5 non-Claude runtimes (cursor, codex, opencode, antigravity, windsurf) Out of scope (per triage): the resolveRuntime() precedence order itself (env > config > default) is unchanged. A separate follow-up noted in the issue (subagent rendering when runtime correctly identifies as 'cursor') is unrelated to branding and not addressed here. * chore(#2395): regenerate golden-install-parity fixtures for new runtime persistence The golden install-tree fixtures capture the post-install state, including ~/.gsd/defaults.json. For non-Claude runtimes, defaults.json now includes runtime: <runtime> — content hash updated for each affected runtime (17 golden-install-parity/*.json files). Claude's defaults.json is unchanged (no runtime key written for Claude — it's the resolveRuntime() fallback). * chore(#2395): drop product names from changeset fragment (product-name-purity gate) * test(#2395): move describe out of fix-1521 fold + add same-runtime idempotence test Code review (correctness subagent) flagged 2 Low test-quality issues: 1. The new Bug #2395 describe was inserted inside the folded:fix-1521-real-install-stamping IIFE callback, muddying test reporting and tracing the regression to the wrong epic. Moved it outside the IIFE close to be a top-level sibling. 2. No explicit same-runtime idempotence test — the suite covered cross-runtime preservation (cursor seed → opencode install) but not 'install cursor twice → second is a no-op'. Added: seeds fresh defaults, installs cursor, captures mtime, installs cursor again, asserts runtime unchanged AND defaults.json mtime unchanged (idempotent, no rewrite churn). * chore(changeset): backfill pr:2446 in .changeset/fierce-ravens-dance.md
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.
