💡 What:

  • Refactored components/elements/Countdown.tsx to initialize timeDif state as null.
  • Added logic to calculate the initial time difference inside useEffect on component mount.
  • Added a conditional return to render null until the client-side calculation is complete.
  • Improved interval handling to explicitly clear the interval when the countdown reaches zero.
  • Replaced consecutive line comments with block comments to satisfy ESLint rules.

🎯 Why:

  • The previous implementation initialized timeDif using Date.now(). Since Date.now() differs between the server (SSR) and the client (hydration), this caused a hydration mismatch error, forcing React to discard the server-rendered HTML and re-render the entire tree, which is a performance penalty (TTI).
  • Fixing this ensures that the initial HTML (empty) matches the hydration state, and the countdown then "pops in" on the client, which is the correct pattern for time-dependent components in SSR frameworks.

📊 Impact:

  • Eliminates a hydration error warning in the console.
  • Prevents a full client-side re-render of the component tree on load.
  • Ensures the countdown is accurate relative to the client's clock, correcting any drift from server time.

🔬 Measurement:

  • Verified via Playwright script that the countdown component loads successfully and is visible after hydration.
  • Verified via code inspection that Date.now() is no longer used in useState initializer.

Summary of Changes

Hello @anyulled, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical hydration mismatch issue within the Countdown component, which previously led to performance penalties and console warnings in server-side rendered applications. By deferring the initial time calculation to the client-side and ensuring the server-rendered output matches the initial client state, the change significantly improves the component's stability and efficiency during hydration.

Highlights

  • Hydration Mismatch Fix: The timeDif state in the Countdown component is now initialized to null to prevent hydration mismatches between server-side rendering and client-side hydration, which previously occurred due to Date.now() differences.
  • Client-Side Initialization: The initial calculation of the time difference has been moved into a useEffect hook, ensuring it runs only on the client after the component mounts.
  • Conditional Rendering: The component now conditionally renders null until the client-side time difference is calculated, preventing the display of potentially incorrect server-rendered values.
  • Improved Interval Management: The setInterval logic has been refined to explicitly clear the interval when the countdown reaches zero, optimizing resource usage.
Changelog
  • components/elements/Countdown.tsx
    • Updated timeDif state initialization from an immediate Date.now() calculation to null.
    • Moved the initial time difference calculation into a useEffect hook to execute on component mount.
    • Added a conditional return statement to render null until the client-side timeDif is determined.
    • Modified the setInterval callback to recalculate the time difference and clear the interval when the countdown reaches zero.

Code Review

This pull request effectively resolves the hydration mismatch issue in the Countdown component by deferring the time calculation to the client side. The refactoring to recalculate the time difference on each interval tick also improves the countdown's accuracy. I've added one suggestion to optimize the performance within the useEffect hook by avoiding repeated date parsing.

Comment thread components/elements/Countdown.tsx
…ess test

Initializes the Countdown state with null instead of Date.now() to ensure the initial server render matches the client hydration. The time difference is then calculated immediately on mount using useEffect, preventing hydration errors and ensuring the countdown starts correctly on the client. Also improved interval logic to clamp to zero and clear interval when finished.

Additionally, updated `cypress/e2e/home/home-editions.cy.ts` to remove an outdated assertion for `h5` tags, which was causing CI failures as the component now uses `div` and `span` elements.

1697-1721: 🛠️ Refactor suggestion | 🟠 Major

Remove duplicate .sponsor-card definition.

This .sponsor-card block is redundant. Line 3 imports _brands.scss via @import "./brands";, which already contains an identical .sponsor-card definition (lines 394-418 in _brands.scss). Having duplicate definitions increases maintenance burden and can lead to inconsistencies if one is updated but not the other.

Event listeners are never removed — memory leak.

The cleanup function passes new anonymous functions () => {} to removeEventListener, but removeEventListener requires the exact same function reference that was passed to addEventListener.

394-418: Duplicate .sponsor-card definition exists in _others.scss.

This exact .sponsor-card block (including the same property updates) is duplicated in _others.scss (lines 1697-1721). Since _others.scss imports _brands.scss via @import "./brands";, one of these definitions should be removed to avoid redundancy and potential maintenance issues.

6-41: Consider refactoring to React state/refs pattern.

Direct DOM manipulation via getElementById/querySelector and manual style.display toggling bypasses React's declarative model. This makes the component harder to test and reason about.

A more idiomatic approach would use useState for visibility and React's event handling:

Inline comments:
In `@__tests__/property/useSchedule.test.ts`:
- Around line 4-11: The test in describe("Property Tests for Schedule Data")
simply asserts Array.isArray on data generated by fc.array (using fc.array and
fc.record) which is tautological; replace it with a meaningful property test
that imports and exercises your schedule logic (for example call
processScheduleData or the real function that transforms/validates schedule
items) and assert invariants (e.g., length preserved, times sorted, titles
normalized), or remove the placeholder test entirely if no property tests exist
yet; locate the test by the describe/it block and references to fc.assert,
fc.property, fc.array and fc.record and either import the actual function (e.g.,
processScheduleData) and assert its properties, or delete the it(...) block.

In @.github/workflows/ci.yml:
- Around line 25-26: The "Security Audit" CI step currently uses the command
"npm audit --audit-level=high || true" which forces a successful exit; remove
the "|| true" fallback so the step fails on high-severity findings (i.e., run
"npm audit --audit-level=high" or otherwise ensure the step does not ignore
non-zero exit codes) to make the Security Audit gate block merges when high
vulnerabilities are found.

In `@ARCHITECTURE.md`:
- Around line 14-18: In ARCHITECTURE.md update the fenced code block that
contains the ASCII diagram starting with "Sessionize API ──► hooks/ ──►
app/[year]/ pages" to include a language identifier (e.g. change the opening ```
to ```text) so the block is lint-friendly; locate the block around that diagram
and replace the fence accordingly.

In `@commitlint.config.js`:
- Line 1: The config currently uses ESM syntax ("export default { extends: [...]
}") but the repo isn't in ESM mode; update commitlint config to use CommonJS by
replacing the ESM export with module.exports = { extends:
["@commitlint/config-conventional"] }; or alternatively enable ESM by adding
"type": "module" to package.json so Node will accept the existing export
default; target the symbol "export default" in commitlint.config.js or the
"type" field in package.json to apply the chosen fix.

In `@components/elements/Countdown.tsx`:
- Around line 32-38: Guard against invalid eventDate by validating the timestamp
and avoiding NaN propagation: in the calculateTimeDif function (and when
computing targetTime) parse eventDate into a date value and check
Number.isFinite(targetTime) or isNaN(targetTime); if invalid, return 0 (or a
sensible fallback) so timeDif never becomes NaN. Move the targetTime calculation
inside calculateTimeDif or revalidate it there to handle prop changes, and
ensure any rendering logic uses the safe non-negative value from
calculateTimeDif.

In `@components/layout/footer/Footer8.tsx`:
- Around line 88-91: Fix the spelling error in the footer link text inside the
Footer8 component: change the hardcoded string "Barceclona" to "Barcelona" where
the JSX renders <Link> with the <Image> icon so the location reads "World Trade
Center, Barcelona".

In `@components/layout/Menu.tsx`:
- Around line 9-16: Wrap each Link inside an li so the ul's direct children are
li elements (update the JSX around the <ul className="sub-menu"> block to render
<li><Link ...>...</Link></li> for each entry), and fix the second link's href so
it matches the active-class check (change the href for the "Home Interior" Link
from "/#" to "/index-2" or alternatively adjust the pathname comparison in the
className logic) — update references to Link, pathname, and className in the
Menu component accordingly.

In `@cypress/e2e/home/home-editions.cy.ts`:
- Line 14: Remove the inline comment "// Venue and date are now in span elements
or nested divs, so we use cy.contains directly" from the test body in
home-editions.cy.ts; simply delete that comment line so the test reads without
explanatory "what" comments, leaving only the assertions (e.g., the
cy.contains(...) calls) which are self-documenting.

In `@lib/shared/navigation.ts`:
- Around line 43-51: The map callback that updates year-scoped URLs (the
anonymous function using link.requiresYear and year in lib/shared/navigation.ts)
should explicitly skip hash links: add a guard at the top of the map callback
that returns the original link immediately if link.href startsWith("#"), then
keep the existing logic (if link.requiresYear &&
!link.href.startsWith(`/${year}`) { ... }). This prevents producing malformed
URLs like `/${year}/#id` while preserving the year-prefixing behavior for other
links.

In `@package.json`:
- Line 28: The "check:docs" script currently copies AGENTS.md to CLAUDE.md
(mutating state) instead of validating equality; update the package.json
"check:docs" script so it only validates that both files exist and are identical
(e.g., use a read-only compare like diff/cmp/git diff and exit non-zero on
mismatch) rather than copying, and keep the existing existence checks for
AGENTS.md and CLAUDE.md; target the "check:docs" script entry in package.json to
implement this change.

In `@scorecard-report.md`:
- Around line 20-53: The published scorecard-report.md is stale: it claims
ARCHITECTURE.md, CLAUDE.md/AGENTS.md, and docs/adr/ are missing even though
those files are added in this PR; regenerate the report from the repository's
final state and commit the updated report. Re-run the project’s scorecard/report
generation step (the same command or CI job that produces scorecard-report.md),
validate that entries referencing ARCHITECTURE.md, CLAUDE.md/AGENTS.md, and
docs/adr/ now pass, and replace the stale scorecard-report.md with the freshly
generated output before merging.

In `@styles/layout/pages/event/_home-8.scss`:
- Around line 205-212: The .btn-area1 is currently hidden by bottom: -10px and
transform: translateY(100%); add a hover reveal or change its default position:
either add a rule like .event2-boxarea:hover .btn-area1 that resets transform to
translateY(0) (and optionally adjusts bottom) to reveal the button on hover, or
remove/modify bottom/transform on .btn-area1 to make it visible by default;
update the related CSS selectors (.btn-area1 and .event2-boxarea) accordingly
and ensure transitions (e.g., transition: transform .2s) are present for a
smooth reveal.

In `@worker/index.ts`:
- Around line 13-15: The activation promise passed to event.waitUntil is being
swallowed by a .catch that only logs via console.error, which makes activation
appear successful even on failure; update the handler so it does not resolve on
error—either remove the .catch or rethrow the error after logging (i.e., in the
.catch call log with console.error("Service worker activation failed:", error)
and then throw error) so the promise stays rejected and event.waitUntil sees the
failure; target the activation promise usage around event.waitUntil and the
existing .catch attached to it.

Outside diff comments:
In `@components/layout/header/Header8.tsx`:
- Around line 9-16: HeaderProps declares isSearch and handleSearch but Header8
does not use them; remove those two props from the HeaderProps interface and
from the Header8 parameter type so HeaderProps only contains scroll and
navigation (and update the function signature export default function Header8({
scroll, navigation }: Readonly<HeaderProps>) accordingly). Then update the
caller in DynamicHeaderWrapper.tsx to stop passing isSearch and handleSearch to
<Header8 ... /> (leave scroll and navigation as before) and remove any related
imports/usages there; also search for other callers of Header8 and update them
similarly.

In `@components/layout/Popup.tsx`:
- Around line 33-40: The cleanup currently passes new anonymous functions to
removeEventListener so the original click handlers (the inline arrow functions
added to closeBtn and noThanksBtn) are never removed; fix this by extracting
those inline handlers into stable references (e.g., const handleCloseClick =
(...) => { ... } and const handleNoThanksClick = (...) => { ... }), use those
variables when calling addEventListener on closeBtn and noThanksBtn, and then
call removeEventListener with the same handleCloseClick and handleNoThanksClick
in the return cleanup to properly detach the listeners.

In `@styles/layout/pages/_others.scss`:
- Around line 1697-1721: The .sponsor-card block in this file duplicates the
definition already provided by the imported stylesheet (`@import` "./brands");
remove this redundant .sponsor-card rule from styles/layout/pages/_others.scss
so the project uses the single canonical definition in _brands.scss, ensuring
you only delete the entire .sponsor-card rule (including its nested img and
&:hover rules) and leave the `@import` "./brands"; line intact.

- Around line 146-154: The test for getAllMainNavLinks is missing validation for

- Around line 6-41: Replace the manual DOM manipulation in Popup (the useEffect
that uses getElementById/querySelector, closeBtn/noThanksBtn and style.display
toggles) with React state and handlers: add a local state like isVisible and
setIsVisible, use useEffect only to start/clear a timer that sets isVisible true
(clearTimeout on cleanup), remove addEventListener/removeEventListener logic,
and wire the close action to onClick handlers on the close element and the
"no-thanks" element in the Popup component JSX so visibility is controlled
declaratively by isVisible.

In `@config/editions/2024.ts`:
- Around line 15-19: The news array currently appends
newsDropdownLinks.slice(1), which relies on ordering and can include wrong or
duplicate items if newsDropdownLinks changes; update the construction of news to
explicitly include or exclude items by property (e.g., filter newsDropdownLinks

In `@eslint.config.mjs`:
- Around line 219-224: The ESLint config for the worker files currently sets

["worker/**/*.ts"]), which disables type-aware `@typescript-eslint` checks; update
that project field to point to the worker tsconfig (e.g.,
"tsconfig.worker.json") so the rule set for worker/**/*.ts uses type-aware
linting via the proper TypeScript project file (ensure the string matches the
tsconfig filename used by your build).

In `@lib/shared/navigation.ts`:
- Around line 40-41: Replace the Object.entries/find lookup with direct property
access: instead of using Object.entries(conditions).find(...) derive the boolean
by checking link.condition and indexing into conditions (e.g., return
!!(link.condition && conditions[link.condition])); this keeps the same behavior
when link.condition is undefined but is simpler and more efficient.

In `@styles/layout/footer/_footer-1.scss`:
- Around line 1776-1783: The .layer1 rule currently sets width: 100% and height:
250px alongside aspect-ratio: 1440 / 230, so remove the redundancy by either
removing the fixed height (use height: auto or remove height) to allow
aspect-ratio to control sizing responsively, or keep the fixed height and delete
the aspect-ratio declaration; update the .layer1 selector accordingly (adjust
the aspect-ratio, height, or both) depending on whether you want a responsive
ratio or a fixed pixel height.

In `@styles/layout/pages/_brands.scss`:
- Around line 394-418: Duplicate .sponsor-card rules are defined in both
_brands.scss and _others.scss; remove the redundant block from one file to avoid
duplication and maintenance drift. Keep the authoritative definition (preferably
the one in _brands.scss) and delete the matching .sponsor-card selector block in
_others.scss (including its &:hover and img nested rules), or alternatively
remove the one in _brands.scss and ensure _others.scss still imports "./brands";
update any imports if you move the definition so only a single .sponsor-card
selector remains in the codebase.

In `@styles/layout/pages/_others.scss`:
- Around line 1683-1694: Remove the duplicated CSS rules for
.sponsors-section-heading and .sponsor-category-title from this file

other duplicates or missing references remain and rebuild to verify styles are

Fix commitlint.config.js to use CommonJS syntax or enable ESM mode.

The config uses export default (ESM) but package.json lacks "type": "module", so Node.js treats .js files as CommonJS. commitlint will fail to load this config and break the commit-msg hook. Either change to module.exports = { extends: ["@commitlint/config-conventional"] }; or add "type": "module" to package.json.

In `@commitlint.config.js` at line 1, The config currently uses ESM syntax
("export default { extends: [...] }") but the repo isn't in ESM mode; update
commitlint config to use CommonJS by replacing the ESM export with
module.exports = { extends: ["@commitlint/config-conventional"] }; or
alternatively enable ESM by adding "type": "module" to package.json so Node will
accept the existing export default; target the symbol "export default" in
commitlint.config.js or the "type" field in package.json to apply the chosen
fix.

⚠️ Potential issue | 🟡 Minor

Guard against invalid eventDate input.

Line 32 can produce NaN for invalid date strings, which then propagates to timeDif and renders NaN parts.

Suggested fix
-    const targetTime = new Date(eventDate).getTime();
+    const targetTime = new Date(eventDate).getTime();
+    if (Number.isNaN(targetTime)) {
+      setTimeDif(0);
+      return;

In `@components/elements/Countdown.tsx` around lines 32 - 38, Guard against
invalid eventDate by validating the timestamp and avoiding NaN propagation: in
the calculateTimeDif function (and when computing targetTime) parse eventDate
into a date value and check Number.isFinite(targetTime) or isNaN(targetTime); if
invalid, return 0 (or a sensible fallback) so timeDif never becomes NaN. Move
the targetTime calculation inside calculateTimeDif or revalidate it there to
handle prop changes, and ensure any rendering logic uses the safe non-negative
value from calculateTimeDif.

⚠️ Potential issue | 🟡 Minor

Hash links will be incorrectly prefixed with year.

Links with href starting with # (e.g., #sponsors) have requiresYear: false in mainNavLinks, but if any hash link ever had requiresYear: true, this logic would produce malformed URLs like /${year}/#sponsors.

Consider adding an explicit check to skip hash links:

       .map((link) => {
-        if (link.requiresYear && !link.href.startsWith(`/${year}`)) {

check:docs is mutating state instead of validating it.

Line 28 copies AGENTS.md into CLAUDE.md during a check step. That masks drift and introduces side effects in CI/local checks.

Scorecard findings are stale and currently incorrect.

Lines 26, 34, 42, and 50 assert missing documentation that exists in this PR (e.g., ARCHITECTURE.md). This makes the published score/report misleading.

Agreed. The property test was a tautological placeholder checking array generation instead of testing schedule logic. I've deleted it.

Done. Added a hover reveal by setting .btn-area1's transform: translateY(0) when hovering over .event2-boxarea, along with a smooth transition.

- Optimized Countdown component to parse eventDate once instead of every interval tick.
- Removed tautological property test for `useSchedule`.
- Ensured service worker activation promise propagates errors by rethrowing.
- Fixed UI hidden button issue in section 8 by adding hover reveal transition.

⚠️ Potential issue | 🟠 Major

Button remains hidden on touch/keyboard-only interaction paths.

Line 174 reveals the CTA only on :hover, while Line 220 keeps it off-canvas by default. On touch devices (and some keyboard flows), hover may not occur, so the Buy Ticket CTA can stay inaccessible.
