+## [2026-11-07] 0.1.29: every ck page names its project
+
+**Category:** `fix`
+**Tags:** `ck`, `review-page`, `gallery`, `do`
+**Risk Level:** `low`
+**Breaking Change:** `no` (callers pass the same flags)
+
+### Summary
+A d20mob staged plan was published as "Phase 9, the ten: staged plan" under the banner line "Code Katz · review page", so nothing on the page said d20mob, and Will could not tell it apart in his artifact list. The review page skill asked for `--title "<product>: <document>"`, but nothing enforced it, and /ck:plan passed a title with no product. Now the renderers find the project's name themselves.
+
+### Detail
+- **The review page.** `scripts/render-review.py` puts the project's name in the banner line ("<project> · review page") and at the front of the `<title>` and the heading ("<project>: <title>"), and skips the prefix when the title already starts with the name. The name is the main checkout's folder of the git repository that holds `--in` (`git rev-parse --path-format=absolute --git-common-dir`, then its parent), so a page built in a worktree still names the project; outside a repository it is the file's folder. `--project` overrides it. Every gate (/ck:prd, /ck:plan, /ck:claude-md and the rest) gets it with no change.
+- **The gallery pages.** A `git grep` across `skills/`, `workflows/` and `scripts/` found two other ways a page gets published. `scripts/render-gallery.py` (brand galleries, design galleries, and `chosen.html`) had "Code Katz · gallery review" and "Code Katz · chosen design"; it now names the project the same way, from the repository that holds the variants JSON, with the same `--project` flag. The gallery contract says so. The workflows that call it need no change.
+- **The /ck:do mockup.** A persona writes `mockup.html` by hand and the session publishes it. The step's rules now ask for the `<title>` `<project>: <what you drew>` and one line above the mockup, `<project> · mockup`, with the session filling in the name.
+- `scripts/project_name.py` holds the lookup both renderers use. One test renders a page from a file in a temporary repository named `demo`, then with `--project x`.

Write only one file, `<runDir>/mockup.html`, and change nothing else: self-contained HTML with styles inline, no script, and nothing loaded from elsewhere except Google Fonts. When the project has mockups of its own, match their look. Use the product's real names, words, and colors, and show the change in place with enough of the screen around it to judge it.

When the project has mockups of its own, match their look. Use the product's real names, words, and colors, and show the change in place with enough of the screen around it to judge it. The page's `<title>` is `<project>: <what you drew>`, and one thin line above the mockup reads `<project> · mockup`. Return the file's path and three lines: what you drew, what you left out, and anything the author should decide." Before you send it, replace `<project>` with the project's name, the folder that `basename "$(dirname "$(git rev-parse --path-format=absolute --git-common-dir)")"` prints, so the page can be told apart in the artifact list.
 
 When it is back, read the file once (the Artifact tool requires it, and it is material), then publish it with the Artifact tool. It is a private link, not a review page; publish every later version from the same file path so the link stays the same. Say "Mockup is ready: `<link>`.", then the persona's left-out and to-decide lines, one line each, then "OK, or what should change?" and stop. When the Artifact tool is not available or is refused, do not retry in this run: give the file's full path in place of the link and say it opens in a browser.
