`DCO Check` is a required status check on this repo and the top failing
check on open contributor PRs, but nothing documented it and nothing
surfaced it locally — a missing `Signed-off-by` trailer only showed up
as a red check after the PR was already open.
## `lefthook.yml`
New `commit-msg` hook that appends the `Signed-off-by` trailer:
```yaml
commit-msg:
commands:
signoff:
run: 'git interpret-trailers --if-exists doNothing --trailer "Signed-off-by: $(git var GIT_COMMITTER_IDENT | sed ''s/ [0-9]* [+-][0-9]*$//'')" --in-place {1}'
```
`GIT_COMMITTER_IDENT` is the identity that performed the commit, which
is what a DCO sign-off certifies and what native `git commit -s` uses.
Committing someone else's work with `--author` or `git commit -C`
therefore signs off as you, not as the original author.
`--if-exists doNothing` makes it idempotent: `git commit -s` still
yields exactly one trailer, and an existing sign-off from a different
signer is preserved rather than supplemented. An empty commit message
still aborts — the hook does not turn one into a commit body containing
only a trailer.
Git runs `commit-msg` for `git commit` and `git merge` only. Other flows
bypass it and need their own sign-off flag — `git rebase --signoff`,
`git cherry-pick -s`. Note `-s` is `--strategy` on `git rebase`, so only
the long flag works there. The header comment and both docs state the
scope rather than promising blanket coverage. Installed by `just hooks`;
`commit-msg` carries no `glob` because it rewrites the message, not
files.
## `CONTRIBUTING.md`
`Before You Open a PR` gains a paragraph on sign-off: commit with `git
commit -s`, what the trailer certifies, that the required `DCO Check`
blocks merge without it, `git rebase --signoff main` to repair
already-pushed commits, and what the hook does and does not cover.
`CI Gate` gains one sentence pointing at `just fix-all` for
formatting-only failures.
## `AGENTS.md`
`Quality Gates` gains the same requirement framed for agents, including
the sequencer caveat and the reminder to include `-s` in
programmatically built commit commands.

Replace the 5-file, ~180-line template surface with a 4-file, ~54-line
goose-modeled set.
## What changed
**`.github/PULL_REQUEST_TEMPLATE.md`** — rewritten to 8 lines: Summary,
Related issue (with inline duplicate-check prompt), Testing. Checklist
and AI-disclosure section removed.
**`.github/ISSUE_TEMPLATE/bug-report.yml` → `bug-report.md`** — replaced
YAML form with plain-markdown template (goose-style frontmatter).
Fields: describe the bug, repro steps, expected behavior, version + OS,
logs/context. Version guidance retained: Settings sidebar footer,
"unknown" accepted.
**`.github/ISSUE_TEMPLATE/feature-request.yml` → `feature-request.md`**
— replaced YAML form with plain-markdown template. Fields: motivation,
proposed solution, alternatives, additional context. Duplicate-check
line at the bottom (goose-style).
**`.github/ISSUE_TEMPLATE/question.yml`** — deleted. `config.yml`
updated to `blank_issues_enabled: true` so questions have somewhere to
go.
**`CONTRIBUTING.md`** — "Before You Open a PR" compressed to four prose
sentences: duplicate search, issue-first recommendation, AI ownership
(absorbs the dropped PR-template field), review cadence. Intro link
updated from the removed question form to plain `/issues/new`.
