Let a rule about comments be a rule about comments - #17
Conversation
`regexp` reads bytes, so a rule written about `// TODO` also matches `let marker = "// TODO";` and there is no way to write the difference down. Two checks now parse the file instead of searching it, in Rust and in Python: `comment_regexp` matches inside a comment node and nowhere else. `trivial_comments` fails a comment every word of which is a word the statements beneath it already name, counting their string literals -- a subset test, so it carries no list of boring verbs to keep edited. Documentation comments are excluded from both. `///` and `//!` are published output rather than remarks to the next reader, and a check that cannot tell them apart from `//` is one whose findings, acted on, delete a public item's documentation. The grammar marks them; nothing here tests the prefix, which is what gets this wrong by construction, `///` being a string that starts with `//`. Five shapes are left alone because their words restate the code by design while the comment does something else: a trailing comment, one line of a multi-line run, a separator, a worked example, a parenthesised aside. A tree that wants its separators gone writes a `comment_regexp` saying so. The tree is scanned by both, which is what the comment rewords across src/ are: `no-before-after-narrative-in-source` refuses a comment that describes what the code replaced, because the reader of a comment cannot see the version it is contrasting itself with.
`no-stale-hook-pins` had been refusing every push here: v0.16.3 is out and this file still copied v0.16.2. The guard is right, and the pin is the copy that goes stale.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Make the failure-mode comment explicitly counterfactual.
Lines 506-511 say “return Ok(None)” as if this branch does that. The branch at Lines 517-526 returns Err(Fatal::new(...)). A reader can misread the comment as the implemented behavior.
Change the sentence to state the rejected alternative explicitly: “If this returned Ok(None), guard::run would count this guard among the ones that passed.” Keep Err(Fatal) as the actual path.
As per coding guidelines, when continuing cannot satisfy the contract safely, the code must return an explicit failure with evidence. The comment must describe that path accurately.
Proposed wording fix

- // return `Ok(None)` instead and `guard::run` counts this guard among the

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Fail when fixture repository initialization fails.
If git init exits nonzero, workspace still returns root. Discovery can then leave the fixture and use an unrelated repository policy. Capture the status and assert status.success() before returning root.
Proposed fix
- Command::new("git")
+ let status = Command::new("git")
.args(["init", "-q", "-b", "main"])
.current_dir(&root)
.stdout(Stdio::null())
.status()
.unwrap();
+ assert!(status.success(), "git init fixture failed: {status}");As per coding guidelines, detect a failed prerequisite at the earliest reliable boundary and return failure evidence.
