CHECKS PASSED
There are no defects that block acceptance. Three remarks are at the end.
1. make check is green on the working copy: format check, astro check with 0 errors and 0 warnings in 38 files, lint, Vitest with 11 files and 314 tests, and the Astro build, exit code 0. I also ran a clean install and make check in a worktree at each of the 5 commits, using a script in the scratchpad. All ended with exit 0. The first two commits have 313 tests and the other three have 314. The worktrees are removed, except the before worktree that existed earlier and that I did not touch.
2. The built page matches: Russian language, theme color 0e7c66, the Russian title of the app, server markup with the same heading in the main element, the favicon under the base path, and the CSS and two JS files under the base path assets.
3. Dependencies. Compared with the base commit, only astro, solid-js, @astrojs/solid-js, @astrojs/check, @solidjs/testing-library, eslint-plugin-solid and prettier-plugin-astro are added, direct vite is removed, and the Node engine is 22.12 or newer. There is one vite version, 8.3.3, deduped in all other packages.
4. Tests. The old-link test with the literal code is present at the commit with the old interface, where make check is green with 314 tests, and at the commit with the Solid island. Against the base commit the number of cases did not change in any file: bill 27, money 4, balances 8, shares 9, transfers 26, base64-url 5, bill-code 21, plural 2, settlement explanation 7, avatar 6. The interface tests have 90 instead of 89, which is the added old-link test. Assertion lines in files unchanged in meaning are identical; only each-table names translated to English differ. In the Solid interface test, a whitespace-insensitive diff against the old version shows only the input helpers moved to fireEvent, the mount replaced by render of App, and translated internal error texts and mock errors. The assertions are the same, plus 5 new in the added test.
5. Lint. Using standard input with existing files in the bill, settlement and sharing folders and a line inserted at the start: without the line the file passes; with it, imports of solid-js and solid-js/web and an astro import give the restricted-imports error and document.body gives the restricted-globals error saying code without the DOM must not use document. With an invented file name the lint fails on a parser error, so existing names were used.
6. Screenshots. I built the current code, ran the Astro preview on port 4176, and took screenshots with the script. 24 screenshots with 0 findings: no console errors, no horizontal scroll, all touch targets at least 44 px. The pixelmatch comparison with the before shots at threshold 0 gives 0 different pixels over 24 files. I looked at 4 screenshots by eye: the example at 360 px in light and dark with the breakdown open, the stress case at 1280 in dark and the empty state at 768 in light. The layout is correct, the breakdown fits at 360 px, the long name wraps neatly and the empty states are in place. The preview is stopped.
7. Cyrillic is only in interface texts, the page title, quotes of the interface and examples in comments, and the middle dot in CSS. Comments and thrown errors are in English. In AGENTS.md and README Cyrillic is only quoted interface text and the Russian name of the app.
8. The diff of the generated harness files against the base is empty. Only the session hook changed in the .claude folder, a translation by decision 12. The sync check returns 0 and the stack in the project config is solid and astro.
9. Commit messages from the log after the base commit use docs, chore, test(ui), build and refactor(ui), all Conventional Commits in English.
10. AGENTS.md and README are fully English in the unchanged working copy. They describe Astro SSG with one Solid island, Vitest with the Solid testing library and its config, astro check, Node 22.12 or newer, Icon and Avatar, the theme color in the Astro page, the Astro preview on port 4173 at the base path, the global Playwright and the language rule. They do not mention createIcon, createAvatar, vite, tsc or the old entry file.
11. Workflows. Both set node-version 22, and setup-node takes the latest 22.x, not below 22.12 (locally it is 22.22.0). Both run a clean install and make check, and the deployment publishes dist. Names are in English. I could not run CI itself.
Remarks that do not block. Criterion 10 about refreshed screenshots is not met in the sense that the files in docs did not change against the base commit and there are no uncommitted changes there; the render is pixel for pixel the same, so regeneration changes nothing, and it is for you to decide whether to skip it or have commit 6 re-save them. In the avatar test the substitution order in the each-table name is swapped: the name used to read takes from name, expected, and now reads takes name from expected, which reads backwards; it is only a test name. The line Closes #9 is not in commits 1 to 5; by the plan it goes in the body of commit 6, which is not made yet.
