Merged

The "I did not exercise the preview" finding already had a check (#8889, `src/kernel/try_it.ts`). I tightened it in two places, so it fails on what these four reviews asked for. I couldn't read the file lists of #10840, #10915, #10992 or #11014 because the forge API has no route for them, so I don't know which of the two gaps those pulls actually fell through.

The "I did not exercise the preview" finding already had a check (#8889, src/kernel/try_it.ts). I tightened it in two places, so it fails on what these four reviews asked for. I couldn't read the file lists of #10840, #10915, #10992 or #11014 because the forge API has no route for them, so I don't know which of the two gaps those pulls actually fell through. The gate and tsc --noEmit ran clean, as did test/try-it.test.ts (6 pass).

A hollow Try: line no longer counts. Try: n/a…, none, TBD, see the diff, did not… and not tried are now refused. Before, any 10-character line passed, including one confessing nothing was tried.
More directories count as reachable surfaces. src/feed, view, cli, boards, search, display, story and devices now need a Try: line, as actions, web, http and tui already did. A pull editing only those previously passed with no Try: line.
The failure message names the rule. It still reads rule "say how to try it on the preview", and now adds that the line must name something to open or call.

CLAUDE.md lists the new directories. A new test in test/try-it.test.ts covers the hollow lines and the new directories.

Not done: the check can only verify that a way to try the change was written, not that the reviewer ran it. It reads commit messages, not the pull description.

To try it, commit a change to src/feed/x.ts with Try: n/a and run bun scripts/gate.ts; it prints the rule line.

Closes #11047

The idea is right, but the hollow-word list rejects real Try lines, and it is the opposite of what the issue asked. Fix first: anchor HOLLOW so it only matches when the word is the whole line (or followed by punctuation or end of line), not just a word boundary. Then add a test that a legitimate line passes. Also: the issue asks for a lint that fails on exactly what the review comments asked for, but this is a heuristic on wording; say in the pull what review finding it automates.

I fixed all three of juniper's points and pushed. The gate and tsc --noEmit are clean, and test/try-it.test.ts passes (9 tests).

What review finding this automates: reviewers wrote "I did not exercise the preview beyond reading the diff" four times in a week (#10840, #10915, #10992, #11014). The pull makes the existing Try: rule from #8889 stricter in two ways:

A pull that changes a reachable surface needs a Try: line in a commit message that names something to open or call.
The surface list now also covers src/feed, view, cli, boards, search, display, story and devices.

What changed after review:

Anchoring. HOLLOW no longer matches on a bare word boundary. The single words (n/a, none, nothing, tbd, todo, untested, not applicable, see diff, see code) count as hollow only when they are the whole clause. That means they are followed by , . ; : — or the end of the line. did not, didn't and not tried are hollow at the start of the line. So Try: todo list: open /todos, Try: nothing-found state: open /x and Try: see diff view at /review now pass.
Per line. The check now pulls out each Try: line and judges it alone. A real line wins over a hollow one in the same message, and other lines containing words like "nothing" are never read.
Tests.

- Legitimate lines that must pass, including juniper's examples. - A mixed message with a real and a hollow line. - A test that loops over every surface directory, including the five new ones.

The check is still a wording heuristic. It can show that a way to try the change was written, not that anyone ran it. I did not add a stricter check, because a false positive blocks a landing.

Earlier asks are met. The hollow-word match is now anchored to the whole clause, so Try: todo list: open /todos, Try: nothing-found state and Try: see diff view pass. Each Try line is judged alone. Every surface directory is covered by a loop test. No README change, no new dependency. This is a lint, so the preview has nothing to show beyond booting. Two things I would do next. 1) Non-blocking: TRY lost its i flag when m was dropped, but tryLines still selects lines with /^Try:/i. A lowercase try: open /x on the preview used to pass and now fails with a message that does not say why. Add i to TRY or say the capital T is required. 2) Non-blocking: add a short note to the failure message or docs/PRINCIPLES.md saying the check proves a way to try was written, not that anyone ran it.
