In `@lib/greetings.ts`:
- Line 34: The greeting template object in lib/greetings.ts with template "It's
late-night {first_name}" is awkward; update the template string in that object
(the entry with template and condition "night") to include appropriate
punctuation or rewording (e.g., "It's late-night, {first_name}" or "Burning the
midnight oil, {first_name}?") so it matches the tone/format of the other
templates; locate the object by its template key and the condition "night" and
replace the template value accordingly.
- Around line 83-91: The hour parsing can yield 24 at midnight causing incorrect
bucket selection; update the logic around hourFormatter/hourPart/hour to
normalize 24 to 0 (or set hourCycle: "h23" on the Intl.DateTimeFormat options)
and ensure hour is an integer in 0..23 before any comparison (i.e., when
computing hour from hourPart.value, if parsed value === 24 set to 0); apply this
change where hourFormatter, hourPart and hour are defined so downstream checks
like hour >= 21 || hour < 5 behave correctly.
In `@package.json`:
- Around line 45-59: package.json currently pins `@better-auth/cli` to ^1.4.21
while runtime uses better-auth ^1.6.5, which can cause schema/CLI/runtime drift;
update the `@better-auth/cli` dependency to ^1.6.x (match the runtime major/minor)
in package.json so the CLI and runtime versions align, then run your package
manager to reinstall and verify lib/auth.ts integrations (createAuthMiddleware,
prismaAdapter, nextCookies, APIError) still work with the updated CLI.

There was a problem hiding this comment.
getGreeting derives firstName from fullName.split(/\s+/)[0], which returns an empty string when fullName has leading whitespace (e.g., " John Doe"), causing the fallback "there" to be used even though a real name exists. Trim (and/or filter out empty parts) before taking the first token so leading/trailing whitespace doesn’t break personalization.

The fallback new Date().getHours() uses the server/client local timezone (and a different Date instance) rather than APP_TIME_ZONE, so if hourPart is ever missing the greeting can become incorrect for the app’s configured timezone. Prefer deriving the fallback hour from the same now value in APP_TIME_ZONE (or pick a deterministic default) to keep behavior consistent.

Changing next, react, and react-dom from pinned versions to caret ranges means fresh installs (or lockfile regenerations) can silently pick up newer minor/patch releases, which can introduce framework-level behavior changes without a code review. Consider pinning these core runtime versions (or documenting why ranges are preferred) to keep deploys reproducible.

| return true; |
There was a problem hiding this comment.
In eligible, the "always" condition returns true, so generic greetings are always included in the selection pool and can crowd out the time/day-specific greetings; it also makes the later eligible.length > 0 ? eligible : ... fallback effectively redundant. If the intent is for always to be a fallback only, exclude always from eligible and only use it when no other conditions match (or explicitly prioritize non-always greetings).

There was a problem hiding this comment.
The fallback new Date().getHours() uses the server/client local timezone rather than APP_TIME_ZONE, which can produce the wrong greeting if formatToParts() ever fails. Consider deriving the fallback hour using the same Intl.DateTimeFormat/APP_TIME_ZONE logic (or reuse hourFormatter.formatToParts(now) with a safer parse) so the timezone is consistent.

There was a problem hiding this comment.
The invisible placeholder heading still contains readable text ("Welcome"). Depending on assistive tech, hidden text can sometimes be announced or included in virtual buffers. Consider marking the placeholder aria-hidden="true" (and/or using an empty non-breaking space) so screen readers don’t encounter a transient heading that is immediately replaced after hydration.

In `@components/chat-area.tsx`:
- Line 324: The span using suppressHydrationWarning in ChatArea is hiding a real
SSR/client mismatch for message timestamps; either ensure ChatArea is truly a
client component that only renders timestamps after client-side fetch, or
implement the pre-hydration placeholder pattern used in components/greeting.tsx:
render a stable placeholder (e.g., empty/placeholder timestamp) during SSR and
swap to the real timestamp after hydration in the ChatArea component (target the
span with class "min-w-max text-xs font-semibold text-muted-foreground" that
currently has suppressHydrationWarning), so server-rendered times are never
shown and hydration mismatches are avoided.

suppressHydrationWarning is a workaround, not a fix — verify SSR path.
suppressHydrationWarning silences the mismatch but does not prevent the server from rendering a timestamp string under the server's timezone that differs from the client's render. If the server renders these spans (e.g., initial page load with historical messages), end users will briefly see times in the server's TZ before the client re-renders after hydration. Given the TZ removal in lib/date-format.ts, this is now an expected difference.
If ChatArea is indeed a client component that only renders message timestamps after client-side data fetch, this is fine. Otherwise, consider the same pattern used by components/greeting.tsx (render a placeholder pre-hydration, real value post-hydration) to avoid the brief flash of incorrect times.

In `@components/chat-area.tsx` at line 324, The span using
suppressHydrationWarning in ChatArea is hiding a real SSR/client mismatch for
message timestamps; either ensure ChatArea is truly a client component that only
renders timestamps after client-side fetch, or implement the pre-hydration
placeholder pattern used in components/greeting.tsx: render a stable placeholder
(e.g., empty/placeholder timestamp) during SSR and swap to the real timestamp
after hydration in the ChatArea component (target the span with class "min-w-max
text-xs font-semibold text-muted-foreground" that currently has
suppressHydrationWarning), so server-rendered times are never shown and
hydration mismatches are avoided.

Comment and code disagree on the specific-vs-generic probability.
The comment says "80% chance" but Math.random() < 0.6 gives specific greetings only a 60% probability. Either update the number or the comment.

dayKeyFormatter no longer specifies a timeZone, so getStableDayKey() depends on the runtime timezone (server vs browser) and may produce different day keys for the same timestamp. Since ChatArea uses this to decide whether to render date dividers, this can cause hydration mismatches (dividers appearing/disappearing) around day boundaries. Consider making getStableDayKey timezone-invariant (e.g., derive the key from new Date(ts).toISOString().slice(0,10) / UTC) or explicitly pass a fixed timeZone for the day-key formatter while keeping display formatting local.

Adding suppressHydrationWarning hides the warning for the date text, but the date-divider structure can still differ between server and client because showDateDivider depends on getStableDayKey(ts) (which is now timezone-dependent after removing the fixed timeZone). That can lead to real hydration errors (extra/missing divider elements), not just warnings. To avoid this, make the day-key computation deterministic across environments (e.g., UTC-based) or defer rendering dividers until after hydration.

better-auth is being updated to ^1.6.5, but @better-auth/cli remains on ^1.4.21 (see devDependencies). The lockfile now includes both 1.4.x and 1.6.x Better Auth packages, which risks version-skew between the CLI/migrations and runtime library. Consider bumping @better-auth/cli to a compatible 1.6.x version (or explicitly validating compatibility) to keep tooling aligned.

The comment says context-specific greetings have an 80% chance to be used, but the code uses Math.random() < 0.6 (60%). Please align the comment and the probability constant so they match (either change the threshold to 0.8 or update the comment).
