A search shared as a link could return every city instead of the ones you asked for. Certain links matched every row while the search box looked empty, and one could be made to match a city name against a country code. A link now searches exactly as typing does.

Summary by CodeRabbit

  • Bug Fixes
    • Search queries containing internal separators are now handled safely and cannot unintentionally match across separate city fields.
    • Separator characters are ignored during search normalization, producing more predictable results for unusual or malformed queries.
    • Empty or separator-only searches continue to return the complete dataset.

…a test

The property list and the value list are stylelint rules inside npm run lint over the same src/**/*.{css,scss} glob, so the guard and its two constants in src/toolchain.test.ts go.
The rule now covers the global sheet as well as the component sheets, and the hand-written SCSS declaration splitter and both stylesheet walkers go with the guard that needed them.
react/jsx-no-literals rejects a rendered text child and a no-restricted-syntax selector rejects a string literal on aria-label, title, placeholder or alt. Deletes the hand-rolled JSX literal walker and the guard behind it.
Two no-restricted-syntax selectors reject an Intl construction and a locale-aware value helper across src/, exempting the formatter module and the tests. The two halves a disallow rule cannot reach, the inline script and the three-instance floor, stay as a reduced guard.
Two no-restricted-syntax selectors scoped to Pagination.tsx reject a ternary with a JSX element on both sides and a two-branch if returning one. That block restates all three selector sets, because the rule is configured per rule and a later block replaces an earlier one outright. Deletes the JSX walkers and the guard behind them.
…dy fails on

The lint gate, the coverage gate, the CI job and the build each already fail on the thing its guard asserted. Their helpers go with them, and the three rules now enforced by nothing say so where they are written.
The real-engine axe sweep was instrumented to report the colour pairs it actually samples. It decides four of the seventeen by value, so those four leave the token math and thirteen stay, including every non-text pair, which no rule in the shipped set measures at all.
color-no-hex and color-named cover every keyword where the hand-rolled matcher named 12 of roughly 148. The glob is the whole lint scope with src/index.css nulling the hex rule, so the two component stylesheets that are .css keep their coverage. The SCSS-variable and retired-token halves stay in the test, which stylelint has no rule for.
declaration-property-unit-allowed-list maps the nine spacing properties and font-size to rem. The visually-hidden mixin nulls it by name for its off-screen clip, because a unit list cannot say "a pixel or two", and widening the rule everywhere for one line would be the wrong trade. The global stylesheet keeps its bounded radius count in the test, which a unit list has no way to make.
outline and its three longhands join text-align, float and clear in the one top-level declaration-property-value-disallowed-list object. Top level rather than inside the override, because stylelint replaces a same-named rule for the files an override matches rather than merging with it, so an outline-only override would drop the inline-axis keys with the gate still green. The self-testing guard-reach block goes with the matchers it tested. That the ring is drawn stays in the test, which no disallow rule can say.
Cut the multi-paragraph rationale blocks to the line or two the conventions ask for. The a11y and ponytail prefixed comments, the NoInfer explanation, the single-consumer hazard on useTheme and both reachability records in tableStateUrl are unchanged in substance. No code moved.
The catalogs carried the most prose and needed the least. The dataset ceiling sentence, the ?url warning, the formatter-cache reason and the six reachability records are all still there.
Comment lines across non-test source fall from 1682 of 3979 to 505 of 2802, and comment runs longer than three lines from 164 to 32. The replaceState reason, the address invariant the cross-document guard holds, and every a11y and reachability record are still in place.
The rules key beside the React recommended set replaced it rather than merging with it, so only one of its rules was on. The colour rule saw no functional notation and the unit rule saw no longhand of the ten properties it named. A toolchain case now asserts the React set is active, which is the positive claim a lint config cannot make about itself.
Five comments kept a conclusion without the fact behind it: the unconditional cache clear, the re-read in subscribeLocale, the pseudo-locale's primary subtag, the reachability of the mixed comparison arms, and why the error codes are a tuple.
The footer indexed an object literal with a slice of catalog copy, so a part named for an Object.prototype member rendered as a link; it is a Map now. The ring rule read a bare 0 channel inside a colour function as a suppression, and the visually-hidden exemption nulled the unit rule for a whole file to excuse one negative margin.
The colour-function rule fired on the token file, which is the one file allowed to declare a colour, and the ring rule read a bare 0 channel inside rgb() as a suppression. The attribute rule flagged a template that carries an interpolation and so composes at runtime. Adds color() to the colour list, and holds the guard's sample file to one that exists.
The search key joins four fields with a NUL and the comment claimed no input could produce one. The address can: ?q=%00 survives trim and matches every row, and a crafted needle spanned two fields. Stripped where the needle is formed, so any caller is covered.

📝 Walkthrough

Walkthrough

This PR adds lint and style enforcement rules, updates tests that now rely on those rules, sanitizes city search terms to remove separator characters, enables Chromatic auto-accept on main, changes footer link lookup to Map, and shortens many code comments without changing behavior.

Changes

Policy, search, and maintenance updates

Layer / File(s) Summary
Lint and style policy enforcement
.stylelintrc.json, eslint.config.js, src/styles/_visually-hidden.scss
Stylelint now bans physical inline-axis properties, inline-direction values, :dir(), outline-cancelling values, non-token colors, and non-rem spacing/type units with scoped exceptions. ESLint now restricts locale call sites, reader-facing string literals in shared components, direction-based JSX branching in Pagination, restores React recommended rules, and expands ignored output paths.
City search separator sanitization
src/api/getCities.ts, src/api/getCities.test.ts
getCities now removes all SEARCH_KEY_SEPARATOR characters before trim and lowercase. A test verifies separator input cannot match across indexed fields and that a separator-only query behaves like an empty query.
Tooling checks and small runtime wiring
src/toolchain.test.ts, src/theme/tokens.test.ts, playwright.config.ts, .github/workflows/ci.yml, src/features/Footer/Footer.tsx
Toolchain tests now verify the lint gate configuration and narrow locale-call-site checks to areas lint cannot inspect. Theme token tests drop style-rule duplication that Stylelint now enforces and narrow remaining checks. The Playwright note matches that change, Chromatic auto-accepts changes on main, and footer URL lookup now uses Map.get.
Documentation comment rewrites
src/App.tsx, src/appState.ts, src/components/DataTable/*, src/components/SearchInput.tsx, src/components/compareRows.ts, src/components/paginate.ts, src/data/worldcities/cities.ts, src/features/CityTable/*, src/features/Header/*, src/features/RootLayout/*, src/hooks/*, src/i18n/..., src/theme/resolveTheme.ts
Many files replace longer JSDoc and inline comments with shorter wording. Runtime logic and public signatures stay the same in these files.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 2fab7

Shared links containing the separator can return every city or search for a different term than entered. Configuration safeguards also lose coverage, so these issues should be resolved before merge.

Keep the three configuration assertions.

package.json still defines explicit browser versions and eslint . --max-warnings 0. vite.config.ts still applies a 100% coverage threshold to the included application source. ESLint and Stylelint cannot enforce these configuration contracts.

containing SEARCH_KEY_SEPARATOR rather than removing those characters; return
the existing non-matching result so separator-only and embedded-separator terms
cannot match all cities. Update the corresponding getCities test case to cover

Comment thread src/api/getCities.ts Outdated
Deleting the separator answered a different search: a term of nothing but one returned every row, and an embedded one silently became the term without it. No field's content holds a separator, so such a term matches nothing.
