* fix(#1936): reconstruct OpenCode review from JSON events; diagnosable empty-output stub On a large review prompt, OpenCode's default `build` agent runs a few read tool calls then ends its turn with zero output tokens (reason:"stop", output:0), so `opencode run --format default` emits empty stdout. The reviewer block redirected stderr to /dev/null and wrote a generic "failed or returned empty output" stub — so the phase silently lost its second independent reviewer with no diagnostic and no timeout. Rewrite the OpenCode reviewer block to invoke `--format json` as the primary call and reconstruct the review from the assistant `text` parts (jq). Capture stderr to a `.err` sidecar (mirrors the Codex block). When the agent emits no text, surface the stop reason, output-token count, and stderr so the failure is diagnosable. Gate the stub on the extracted CONTENT, not the output file size — an empty jq extraction still prints a lone newline that a `[ -s file ]` check would treat as populated. Document the wall-clock timeout as a Bash-tool param (macOS lacks GNU timeout; opencode has no native timeout flag). review.md was already at the DEFAULT size-tier ceiling (40956/40960), so the fix cannot fit without reclassifying it into the LARGE tier (it is a multi-reviewer orchestration file that outgrew "focused single-purpose"; 43.4 KB sits well under the LARGE high-water mark). Recapture the 16 golden-install fixtures — the diff is exactly one review.md hash per runtime. Regression block folded into review-default-reviewers-workflow.test.cjs (new bug-NNNN test files are not accepted).

Add tests/opencode-review-reconstruction.property.test.cjs. It extracts the two shipped jq programs (OPENCODE_REVIEW, OPENCODE_DIAG) verbatim from gsd-core/workflows/review.md and runs the real jq — not a reimplementation — so the shipped logic is what gets tested. Properties: the reconstructed review equals the newline-join of every assistant text part (order preserved); a stream with no text part reconstructs to empty (drives the #1936 stub); null/absent text parts are dropped, never rendered as "null". Plus example-based coverage of the diagnostic edges the reviewer cited: missing .tokens.output and no step_finish degrade to "?"; non-JSON stdout makes jq fail rather than masquerade as a review. Verified the invariant has teeth (a comma-join jq fails the property). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(#1936): skip jq reconstruction property test when jq is absent The property test shells out to `jq`, which GitHub's windows-latest runners do not ship (macOS/Linux runners do). `execFileSync('jq')` therefore ENOENT-failed the whole file on `test (windows-latest, *)`. Probe `jq --version` at load and skip the suite when jq is not on PATH — the reconstruction logic is platform-independent, so the assertions still run in full on every jq-present runner (mirrors how golden-install-parity skips on win32). Verified: jq present → 7 pass; jq removed from PATH → 7 skipped, 0 fail. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(#1936): skip jq reconstruction property test on Windows, not just when jq is absent The prior guard skipped only when `jq` was absent from PATH — but the windows-latest runners DO ship jq, so the suite still ran there and failed with `jq: parse error: Invalid numeric literal` (confirmed from the CI job log). Root cause is Node's child_process argument quoting mangling the jq program (it embeds double quotes) on Windows, not the shipped review.md logic — the macOS/Linux legs pass. Gate the suite on `process.platform === 'win32'` (still also skipping when jq is absent), mirroring golden-install-parity's win32 skip. Logic is platform-independent and fully asserted on every macOS/Linux CI leg. Verified: macOS → 7 pass; simulated win32 → skips.

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.
