 ### Changed
 - **`review/checklist.md` starts with a PR type taken from the changed paths:** docs-only, CI/infra, scripts/tooling, application or mixed. Code under `bin/`, `scripts/` or `tools/` that is not shell, batch or PowerShell, package manifests and lockfiles, prompt templates (`*.tmpl`) and skill Markdown count as application, and so does any path the reviewer can't place. Application and mixed diffs run every category exactly as before; nothing is skipped.
 - **On a CI/infra, scripts/tooling or docs-only diff,** Gate Integrity, Shell Injection, Completeness Gaps, Distribution & CI/CD Pipeline and the new Repo Conventions & Platform Fit category always run. Every other category with nothing to check is reported once, in one line (`Not applicable (PR type: <type>): <categories>`), and never counts as passed.
-- **New category, Repo Conventions & Platform Fit:** new files use the languages, tools and naming the repo already uses for the same job, scripts run on the platforms the CI runners and docs target, and new tooling doesn't repeat an existing tool. A finding has to name its concrete consequence.
+- **A new Repo Conventions & Platform Fit category** checks that new files use the languages, tools and naming the repo already uses for the same job, scripts run on the platforms the CI runners and docs target, and new tooling doesn't repeat an existing tool. A finding has to name its concrete consequence.
 - **Distribution & CI/CD Pipeline gains script checks:** strict mode (`set -euo pipefail` or the repo's equivalent) in scripts CI or a build relies on, quoted variables, commands that work on the CI runners' OS, third-party actions pinned to a release tag or commit SHA, and tools installed at a pinned version. These checks apply to test-only CI changes too.
 
 ### Tests
-- `test/review-checklist-pr-type.test.ts` builds a classifier from the patterns the checklist itself lists and runs real path sets through it: a `.tmpl` change, `bin/` TypeScript, an extensionless `bin/` executable, `package.json` + `bun.lock`, a workflow-only change, a `.bat` add, docs, and mixed changes. It also checks the five types, the always-run list, the one-line not-applicable report, the new category and the line budget. All 19 tests fail on the previous checklist.
