docs: add PR-REVIEW.md checklist and link from CONTRIBUTING

Publish the 13-criteria PR review checklist the maintainer runs on
every incoming PR so contributors (and their coding agents) can run
the same pass before opening, surfacing problems before the review
round trip. CONTRIBUTING.md gets a new 'Self-review against the
project review checklist' subsection under 'Submitting pull requests'
and a Further Reading entry. CHANGELOG [Unreleased] gets an Added
entry.

# PR Review Checklist
<!-- markdownlint-disable MD013 -->
This is the 13-criteria checklist the maintainer runs against every
incoming PR. The first pass on any submission is exactly this list,
so executing it yourself before opening — or after pushing a fresh
revision — saves a review round trip and surfaces problems faster.
The document is also written so you can hand it to a coding agent
(Claude Code, Copilot, Cursor, Aider, etc.) with "review my branch
against this checklist" and get a structured pass. The agent gets
better results than a free-form "review my PR" because every concern
the maintainer cares about is enumerated below.
## Step 1 — Should this even be reviewed?
Skip the review (and say so) if the PR is:
- closed, merged, or marked draft
- automated (bot author, dependabot, etc.) and trivially OK
- so small and obviously correct (typo fix, single-line doc tweak)
that a thirteen-point pass is overkill — a one-paragraph informal
review is better in that case
## Step 2 — Gather context
Read these *before* analyzing the diff so the review is grounded:
1. PR metadata. Title, body, author, head ref, base ref, head SHA,
base SHA, mergeable status, CI rollup, commit list.
```bash
gh pr view <num> --json title,body,author,headRefName,baseRefName,headRefOid,baseRefOid,mergeable,statusCheckRollup,commits
```
2. The diff.
```bash
gh pr diff <num>
```
3. Base-branch freshness. How many commits have landed on the PR's
base since the PR forked from it.
4. Project guidance. Read [CLAUDE.md](CLAUDE.md) at the repo root and
any nested `CLAUDE.md` in directories the diff touches. These
describe project-specific conventions and constraints not visible
from the diff alone.
5. Related work on GitHub. Skim the [open issues](https://github.com/jmcorgan/fips/issues)
and other [open PRs](https://github.com/jmcorgan/fips/pulls) for
work that overlaps, duplicates, partially addresses, or is unblocked
by this PR.
6. For "this looks wrong" observations later: `git blame` the modified
lines and read recent commit history on the same files for context
before flagging something as a problem. What looks like a bug at
first glance is often a deliberate workaround documented in a prior
commit message.
## Step 3 — The 13 criteria
The review must address all 13 criteria below at some point. They
group naturally into PR hygiene, diff content, and cross-cutting
concerns — but the report itself is *not* organized this way; see
Step 4.
### Group A — PR hygiene (structural review)
1. **PR body and issue cross-reference**. Does the body accurately
describe the change (feature added or bug fixed) and match what
the diff actually does? Is there an associated issue that
should be referenced via `Closes #N` / `Fixes #N`?
2. **Commit hygiene and base freshness**. Is the PR a clean set of
commits (or a single commit) representing appropriately chunked
development items, or are there intermediate "WIP" / "fix typo" /
"address review" commits that should have been squashed? Is the
branch based off a recent `maint` / `master` / `next`, or has the
base diverged far enough that rebase work is needed?
3. **Commit message quality**. Are the commit messages well-structured
(subject + body where the change warrants), accurately referencing
everything actually in each commit, and free of extraneous footers
— particularly coding-assistant attribution (`Generated with
Claude Code`, `Co-Authored-By: Claude`, similar from other AI
tools)?
### Group B — Diff content
4. **Does it do what it says it does**. Walk each claimed behavior
from the PR body against the actual diff lines.
5. **Coherent whole**. Are all parts of the diff in service of the
stated goal, or are there drive-by formatting changes, unrelated
touch-ups, or scope creep?
6. **Fits the codebase as a natural extension**. Does the new code
use existing idioms, helpers, error types, and patterns, or does
it introduce new ones where existing ones would have served?
### Group C — Cross-cutting concerns
7. **New dependency surface**. Any new crates, system deps,
build-time requirements, or external-service dependencies?
8. **New test coverage**. Are the new code paths covered, are the
tests scoped correctly (unit / integration / end-to-end), and
are there obvious test gaps? Don't reflag anything CI already
enforces (formatting, lint, type errors, unit-test pass/fail).
9. **Documentation impact**. Does this need a CHANGELOG entry,
rustdoc updates, design-doc changes
([docs/design/](docs/design/)), README adjustments, or operator
doc updates in [docs/](docs/)?
10. **Security vulnerabilities**. Any new attack surface,
untrusted-input parsing, `unsafe` blocks, panic-on-untrusted
paths, secret-handling concerns, or side-channel exposure?
11. **Rust and OSS best practices**. Idiomatic error handling, no
silently-swallowed errors, no `unwrap` / `expect` on untrusted
input, no `#[allow]` without justification, appropriate
visibility (`pub` vs `pub(crate)` vs private), naming, and
module shape.
12. **Overlap with existing work**. Cross-check open issues and
other open PRs (and recently closed/merged ones) for related
work that overlaps, duplicates, partially addresses, or is
unblocked by this PR.
13. **Other concerns**. Anything not captured above — wire-format
implications, branch-flow questions (`maint` vs `master` vs
`next`; see [docs/branching.md](docs/branching.md)),
deployment / packaging impact, contributor coordination needs,
fragility notes for future maintainers.
## Step 4 — Compose the review
The review report is **not** a Q&A walk through the 13 criteria.
Write it as natural prose in a coherent, integrated narrative that
reads start-to-finish. All 13 criteria must be addressed at some
point in the body, but ordering, grouping, and emphasis follow the
actual shape of THIS PR — lead with what matters most for this PR,
not a fixed template.
A typical shape that often falls out naturally:
- **Opening paragraph**: what the PR does and the headline
observations (subsumes criteria 1 and 4).
- **Substantive body**: diff analysis, design fit, cross-cutting
concerns, surprises, fragilities, missing coverage,
cross-PR/issue overlap, anything unusual. Don't reference
criterion numbers in the prose.
- **Closing**: short summary and a proposed disposition — *land*,
*land-with-followups* (list them), *request-changes* (with the
blocking items called out), or *hold-for-thematic-batch*.
Short subheadings are fine where they aid scanning. Bullets are fine
for enumerable items (test names, file paths, follow-up actions).
Avoid bullets that just enumerate criterion responses.
## Step 5 — Filter aggressively
Quality over quantity. Do not flag:
- Pre-existing issues on lines the PR did not modify
- Issues that linter, type-checker, formatter, or CI would catch
- Pedantic style nitpicks a senior engineer would not call out
- Likely intentional changes related to the broader goal
- Things explicitly silenced by an `#[allow]` with justification
- Stylistic preferences not anchored in `CLAUDE.md` or the
surrounding codebase's idioms
When in doubt about whether something is worth surfacing: would a
senior maintainer skim past it, or would they want it raised?
Skim-past items don't belong in the report.
For every issue you *do* surface, include a concrete fix suggestion
inline ("rename X to Y", "extract this into the existing helper at
`foo.rs:42`", "add a test exercising the `Err` branch") so the
author can act without a round-trip.
## Step 6 — Citation discipline
When the review references a specific code location, use full-SHA
GitHub permalinks so the link survives future history rewrites:
```text
https://github.com/jmcorgan/fips/blob/<full-40-char-sha>/<path>#L<start>-L<end>
```
For multi-line ranges include at least one line of context before
and after the line(s) being discussed. After `gh pr checkout <num>`,
use `git rev-parse HEAD` to grab the full SHA — never partial SHAs
in permalinks.
## Notes
- The review is one human's read of the PR. Confidence calibration
matters: distinguish "this is a blocker" from "this is worth asking
about" from "this is a fragility note for future maintainers." The
closing disposition makes the action explicit.
- If a re-review is triggered after the author pushes new commits,
lead with the delta from the prior review rather than re-walking
the whole PR.
- This checklist exists to surface problems, not to assign blame.
If you're running it as the author or via an agent, treat each
finding as "would the maintainer ask about this?" — and either fix
it before opening, or pre-empt it in the PR body so the maintainer
doesn't have to ask.
