docs: v3.1.0 post-release records -- the libretro sync and three lessons by doublegate · Pull Request #597 · doublegate/RustyNES

doublegate · 2026-10-08T13:32:33Z

Post-release records for v3.1.0 "Bellwether" (#594). Docs only.

docs/libretro/UPSTREAM_SYNC.md: the v3.1.0 sync. The .info differed from upstream only in display_version; Update rustynes_libretro.info for RustyNES v3.1.0 libretro/libretro-super#2134 is open with that one line. The docs page needs no PR.
docs/agents/tooling-traps.md: two traps this release hit. git show <tag>:<path> > FILE on an unfetched tag writes an empty file, and workflow_dispatch runs only a workflow on the default branch.
docs/agents/review-bots.md: slicing an over-100-file PR as code versus docs lets both slices pass the pre-commit hooks without --no-verify.

Summary by CodeRabbit

Documentation
- Clarified guidance for splitting large reviews, including keeping slices aligned with the release and capturing findings from both.
- Added notes about Git tag and workflow dispatch pitfalls.
- Updated the upstream sync record with version details and the related PR status.

The libretro sync: the core's .info differed from upstream's only in display_version, so libretro/libretro-super#2134 carries that one line, copied from the v3.1.0 tag. The docs page needs no PR: it names no version and no libretro-visible feature changed. Two traps, in docs/agents/tooling-traps.md: - `git show <tag>:<path> > FILE` on a tag not fetched locally writes a zero-byte FILE (the shell creates it first). It reached the libretro-super fork as a pushed 38-line deletion before the diff was read; caught before the PR and repaired by amend. Fetch the tag first and check `-s` and the diff before committing. - `workflow_dispatch` runs only a workflow on the default branch: the sibling's new ladder.yml could not run before its PR merged (HTTP 404). And in docs/agents/review-bots.md, a better way to slice an over-100-file PR for CodeRabbit: code versus docs. Each half then passes the pre-commit hooks, so no slice needs `--no-verify`. Re-derive the partition on every sync, because a newly touched path is otherwise left out of both slices.

📝 Walkthrough

Walkthrough

The documentation now covers large-PR slicing checks, two tooling traps, and the v3.1.0 upstream sync status.

Changes

Review-slicing guidance

Layer / File(s)	Summary
Large-PR slicing guidance `docs/agents/review-bots.md`	Adds an extension-based code/docs partition, records pre-commit results, and requires re-deriving and validating the partition on each sync. It also records findings from both slices.

Tooling traps

Layer / File(s)	Summary
Git and workflow guidance `docs/agents/tooling-traps.md`	Documents that `git show <tag>:<path> > FILE` can create an empty file if the tag is unavailable locally, and that `workflow_dispatch` requires the workflow to be on the default branch.

Upstream sync record

Layer / File(s)	Summary
v3.1.0 sync status `docs/libretro/UPSTREAM_SYNC.md`	Records the upstream `.info` difference, the `libretro-super` PR, and why no `libretro/docs` PR was needed.

Priority: ⬇️ Low

Antigravity review (Gemini via Ultra)

This is a trivial documentation update that records the v3.1.0 libretro sync and adds three procedural lessons regarding review bot slicing, git output redirection, and workflow dispatch limitations.

Blocking issues

None found.

Suggestions

docs/agents/review-bots.md (around line 40): Depending on a hardcoded list of file extensions to partition PR slices is brittle. Consider documenting a specific shell command that automatically bins git diff --name-only output into the two slices to guarantee no file is ever dropped.

Nitpicks

docs/libretro/UPSTREAM_SYNC.md (line 185): Consider linking the libretro-super PR number directly in the section header for faster reference, similar to how issue numbers are referenced in the agent docs.

Antigravity review (Gemini via Ultra)

This documentation PR updates the libretro sync record for v3.1.0 and logs new operational traps regarding review bot PR slicing, unfetched git tags, and workflow dispatch limitations.

Blocking issues

None found.

Suggestions

This is a trivial documentation change.
docs/agents/review-bots.md (line 42): The phrase "Two things to keep:" is slightly abrupt; consider "Two rules to keep:" or "Two things to note:".
docs/agents/tooling-traps.md (line 38): The workflow_dispatch limitation applies to the GitHub Actions backend itself, not just the gh CLI. Consider clarifying that the web UI and REST API will also fail for workflows not on the default branch.

Nitpicks

docs/libretro/UPSTREAM_SYNC.md (line 174): You can drop the libretro/ prefix in the markdown link text since the URL already provides the full context.

The v3.1.0 record had been inserted inside the v3.0.0 section, ahead of that section's table of multi-field changes, so as rendered the table read as describing v3.1.0, whose PR (#2134) changes display_version only. It is now its own "Sync for v3.1.0" section after the v3.0.0 one. Found by Copilot on #597.
