Inline comments:
In `@backend/controllers/project.controller.js`:
- Around line 703-710: The current code only checks that domains is an array but
can still contain non-string or empty entries; update the validation around the
domains variable to ensure every element is a non-empty string (e.g., typeof
entry === "string" && entry.trim().length > 0) before calling
Project.findOneAndUpdate, return res.status(400) with an explanatory error if
validation fails, and pass a sanitized array (trimmed values) into the { $set: {
allowedDomains: domains } } update so Project.findOneAndUpdate (using
req.params.projectId and req.user._id) only persists valid domain strings.

In `@backend/controllers/release.controller.js`:
- Line 5: Replace the hardcoded ADMIN_EMAIL constant and any direct equality
checks against it with a configurable authorization approach: remove the const
ADMIN_EMAIL and instead read an allowlist from an environment variable (e.g.,
process.env.ADMIN_EMAILS split by comma) and/or use role/claim-based checks on
the authenticated user (e.g., req.user.role === 'admin'); update the
authorization logic that currently compares emails (the occurrences that
reference ADMIN_EMAIL) to consult the allowlist and/or the user's role/claims,
and move the check into reusable middleware/helper (e.g., isAdmin(req)) so
rotation and testing are easier.
- Around line 21-33: The release `content` field is stored raw which allows
stored XSS; before constructing and saving the Release (where you reference
req.body.content and call new Release(...) / newRelease.save()), sanitize or
strip unsafe HTML on the server side (e.g., use a well‑maintained sanitizer like
sanitize-html or server DOMPurify) to allow only an approved subset of
tags/attributes or to remove scripts and event handlers, validate the sanitized
result is non-empty, and then save that sanitized content; alternatively ensure
the frontend always escapes/encodes content on render, but the immediate fix is
to sanitize req.body.content prior to new Release(...) and newRelease.save().
- Around line 40-47: The current emails.forEach loop calls
emailQueue.add('release-email', { email, version, title, content }) but doesn't
await the promises, so enqueue failures are missed; change the loop to collect
the promises (e.g., map over emails to call emailQueue.add(...)), await
Promise.all on that array inside the relevant controller function (the block
containing emails.forEach), and handle/rethrow or respond with an error if any
Promise rejects so the API only returns success when all jobs are enqueued.

In `@backend/middleware/verifyApiKey.js`:
- Around line 76-83: The wildcard origin check should compare hostnames, not the
full origin; replace use of originUrl = new URL(origin).origin with extracting
hostname via new URL(origin).hostname and then, in the allowedDomains.some
callback (the logic referencing allowedDomains and baseDomain), treat a
'*.example.com' entry as matching only when hostname === baseDomain or
hostname.endsWith('.' + baseDomain) to enforce the subdomain boundary; leave the
exact-match branch to compare hostname === domain for non-wildcard entries.

In `@backend/models/Project.js`:
- Around line 48-51: The Project schema in backend/models/Project.js is missing
the rateLimit field so per-project overrides read by
backend/middleware/projectRateLimiter.js (req.project.rateLimit) are never
persisted; add a rateLimit property to the Project model (e.g., rateLimit with
the appropriate type expected by projectRateLimiter—Number for a simple max or
an object/Schema.Types.Mixed if the middleware expects window/max pairs—and set
a sensible default/null) so saving a project stores the override and
req.project.rateLimit is populated when loaded.

In `@backend/queues/emailQueue.js`:
- Around line 18-22: Logs in the email queue are printing full recipient
addresses (PII); update the logging in the email processing code that calls
sendReleaseEmail (the console.log and console.error lines that reference the
email variable) to avoid raw emails by either logging a masked version (e.g.,
show only local-part initials and domain) or use the job ID/recipient hash
instead, and apply the same change to the other occurrence referenced around the
second log (line ~37) so no raw email addresses are written to logs.
- Around line 19-23: The worker currently awaits sendReleaseEmail(email, {
version, title, content }) but ignores its returned error object, so provider
failures can be treated as successes; update the handler in emailQueue.js to
inspect the result from sendReleaseEmail (e.g., returned value or { error }
payload), and if an error is present, log the error with context (email,
version) and rethrow or return a rejected promise so the job is marked failed;
ensure any existing try/catch around sendReleaseEmail uses the captured result
(not just thrown exceptions) to decide success vs failure.

In `@backend/utils/emailService.js`:
- Around line 52-57: The current email service logs failures and returns {data,
error} or {error} (the inner callback branch and the outer catch in
backend/utils/emailService.js) which lets callers treat failures as successes;
update both places to log the error and then throw the error (or rethrow a
wrapped Error with context) instead of returning an object—locate the
error-handling in the function that calls the resend client callback (the if
(error) console.error("[Resend Error]", error); return { data, error }; block)
and the enclosing catch block (console.error("[Email Service Error]", error);
return { error };) and replace the returns with throw error (or throw new
Error(`[EmailService] send failed: ${error.message || error}`)) so callers
receive a rejected exception.

In `@frontend/src/pages/ProjectDetails.jsx`:
- Around line 173-175: The two roll buttons share the boolean isRegenerating so
both spin together; change this to track which key is regenerating (e.g., use
state like regeneratingKey: null | 'publishable' | 'secret'), update
handleRegenerateKey(keyType) to set regeneratingKey to the keyType before async
work and clear it on finish/error, and update each button’s disabled and spinner
class logic to check regeneratingKey === 'publishable' or === 'secret' instead
of isRegenerating so only the button for the active key shows loading.

In `@frontend/src/pages/ProjectSettings.jsx`:
- Around line 1045-1063: The icon-only remove button lacks an accessible name;
update the JSX button that calls removeDomain(domain) (the element rendering <X
size={16} />) to include an aria-label (or aria-labelledby) such as
aria-label={`Remove domain ${domain}`} so screen readers get meaningful context;
you can also keep a title attribute for tooltip parity but ensure aria-label is
present and dynamic per domain.

In `@frontend/src/pages/Releases.jsx`:
- Around line 93-96: In Releases.jsx replace the div that uses
dangerouslySetInnerHTML with a plain-text rendering: remove
dangerouslySetInnerHTML and its .replace(/\n/g, '<br>') call and instead render
{release.content} as the div's child, keeping the existing style but add
whiteSpace: 'pre-wrap' (e.g., style={{ color: 'var(--color-text-muted)',
lineHeight: '1.7', fontSize: '1.05rem', whiteSpace: 'pre-wrap' }}). This
preserves newlines safely and eliminates the XSS risk from
dangerouslySetInnerHTML while retaining the visual formatting for the Releases
component.

Outside diff comments:
In `@frontend/src/pages/CreateProject.jsx`:
- Line 133: Update the button text in the CreateProject component that currently
reads "I have saved the key, Go to Dashboard" to use plural "keys" for
consistency with the warning copy; locate the JSX button/label in
CreateProject.jsx (the element rendering that exact string) and change it to "I
have saved the keys, Go to Dashboard" (or similar pluralized phrasing).

Nitpick comments:
In `@backend/app.js`:
- Line 89: The /api/releases route is mounted without the request controls used
elsewhere; add and apply the same rate-limiting (and optional request-logging)
middleware when mounting releaseRoute. Create or import the existing limiter
middleware (e.g., rateLimiter or express-rate-limit config) and optional
requestLogger, then replace or change the mount to use them with releaseRoute
(for example, app.use('/api/releases', rateLimiter, requestLogger,
releaseRoute)) so the releases endpoints receive the same throttling/logging
behavior as neighboring API groups; ensure you import the middleware and place
the mount near the other API group mounts for consistency.

In `@backend/models/Release.js`:
- Around line 18-21: The Release model currently hardcodes publishedBy default;
remove the default and make the publishedBy schema field required (i.e., update
the publishedBy field in the Release schema to type: String and required: true)
and then ensure the release creation flow sets publishedBy from the
authenticated user context (e.g., in your createRelease / release creation
handler use req.user.email or equivalent to populate publishedBy before saving).
This keeps the model flexible and ensures attribution comes from the
authenticated user rather than a fixed value.

In `@frontend/src/pages/ProjectSettings.jsx`:
- Around line 926-938: The addDomain handler currently only checks for
duplicates but accepts invalid formats; update the addDomain function to perform
lightweight client-side validation on newDomain (after trimming) before calling
handleUpdate: allow a single "*" or a leading wildcard like "*.example.com" or a
bare hostname/hostname with subdomains (no http:// or https://, no path, no
ports), reject strings that start with "http://" or "https://" or contain "/" or
":" (except the "*" pattern) and call toast.error with a clear message for
invalid formats; keep the existing duplicate check (domains.includes(domain))
and only build updated = [...domains, domain] and call handleUpdate(updated)
when validation passes, then setNewDomain(""). Ensure the validation logic is
implemented inside addDomain and references newDomain, domains, handleUpdate,
setNewDomain.

Duplicate comments:
In `@backend/routes/releases.js`:
- Line 16: The POST / route is authenticated but unthrottled (router.post('/',
authorization, createRelease)); add a rate-limiting middleware to protect the
createRelease handler and downstream email-queue side effects by importing or
creating an express rate limiter (e.g. express-rate-limit or existing shared
limiter), configuring sensible window and max values (e.g. short window for
per-IP/user write ops), and inserting that middleware into the route chain (e.g.
router.post('/', authorization, rateLimiter, createRelease) or router.post('/',
rateLimiter, authorization, createRelease) depending on whether you want to
limit unauthenticated attempts) so bursts are throttled while legitimate users
still can create releases.

Inline comments:
In `@backend/controllers/release.controller.js`:
- Around line 5-6: The module reads ADMIN_EMAIL into the constant ADMIN_EMAIL
but does not fail fast if it's undefined; add an explicit guard immediately
after the const ADMIN_EMAIL = process.env.ADMIN_EMAIL; statement that checks for
a falsy value and throws a clear Error (e.g., throw new Error('ADMIN_EMAIL
environment variable is required')) so the app fails to start deterministically
when ADMIN_EMAIL is not configured; ensure the check runs at module
initialization (not inside a route) so functions that rely on ADMIN_EMAIL (e.g.,
any auth logic in this controller) never run with a missing value.

In `@backend/utils/emailService.js`:
- Around line 63-70: The escapeHtml function can throw when passed
null/undefined or non-string values; make it null-safe by coercing its input to
a string up front (e.g., use String(unsafe) or a typeof check) before performing
the chained .replace calls so sendReleaseEmail and other callers won't crash on
malformed payloads; update the escapeHtml helper accordingly and ensure callers
still pass values but rely on the helper to defensively handle non-strings.
- Line 6: The current initialization of the resend client silently falls back to
a dummy key; update the logic around the Resend constructor (the resend
variable) to fail fast when no real key is provided: remove the
're_dummy_key_for_testing' fallback and instead read
process.env.RESEND_API_KEY_2 || process.env.RESEND_API_KEY, and if that value is
missing and NODE_ENV !== 'test' throw a descriptive Error (or exit) so missing
production config is detected at startup; allow the dummy/test key only when
NODE_ENV === 'test' (or when an explicit test flag is set).

In `@frontend/src/config.js`:
- Line 3: Replace the hardcoded ADMIN_EMAIL constant by reading it from an
environment-config mechanism so the frontend and backend use the same source of
truth; change the export for ADMIN_EMAIL in config.js to derive its value from
process.env (or your app's runtime config provider) with a safe fallback only
for local dev, and ensure the frontend build system/documentation instructs
setting the same ADMIN_EMAIL env var used by backend (reference symbol:
ADMIN_EMAIL in config.js and the backend check in release.controller.js) to
avoid divergence and remove PII from source.

Duplicate comments:
In `@backend/controllers/release.controller.js`:
- Around line 21-37: Sanitize the user-controlled content before saving to
prevent stored XSS: validate and replace req.body.content with a server-side
sanitized version (e.g., using a library like sanitize-html or DOMPurify for
Node) before you construct newRelease; update the code around the extraction
const { version, title, content } = req.body to sanitize the content variable
and pass the sanitized value into new Release({ version, title, content:
sanitizedContent, publishedBy: req.user.email }); also add the required
import/dependency and unit tests to ensure dangerous HTML/scripts are stripped
or escaped.
- Around line 45-57: The current use of Promise.all over emails.map with
emailQueue.add can reject on the first enqueue error and obscure that the
release was persisted and some jobs were queued; change to a resilient enqueue
loop that collects per-email results (success/failure) by awaiting each
emailQueue.add inside a try/catch (or using Promise.allSettled on the
emails.map) so you can record failures without throwing, then respond with
res.status(201).json including the total attempted, succeeded, and failed counts
and a list or summary of failed email addresses; update code paths around
Promise.all, emails.map, and emailQueue.add to return partial-results and avoid
duplicative retries.

Nitpick comments:
In `@backend/controllers/project.controller.js`:
- Around line 700-729: The updateAllowedDomains handler currently trims and
filters domains into cleanedDomains but doesn't remove duplicates; update the
cleanedDomains creation inside updateAllowedDomains to deduplicate values (e.g.,
use a Set or Array.prototype.filter with indexOf) so only unique, trimmed,
non-empty strings are stored, then continue to persist via
Project.findOneAndUpdate and update caches via deleteProjectById/setProjectById
and deleteProjectByApiKeyCache as before.

In `@backend/middleware/verifyApiKey.js`:
- Line 68: The origin validation currently falls back to req.headers.referer
which is inconsistent with CORS semantics; change the code in verifyApiKey
middleware to use only req.headers.origin (i.e., const origin =
req.headers.origin) and remove any logic that treats referer as an equivalent
fallback, updating any subsequent checks or error messages that reference
referer so they assume Origin may be undefined for same-origin requests.

In `@backend/models/Release.js`:
- Around line 14-21: The Release model's required fields 'content' and
'publishedBy' lack normalization and size limits; update the schema in
Release.js to add trim and maxlength constraints (e.g., set a reasonable max for
'content' like 10000 chars and for 'publishedBy' like 100 or as your domain
requires) and normalize 'publishedBy' (trim and optionally lowercase) to prevent
oversized payloads and inconsistent author values; ensure validation messages
remain descriptive so Mongoose rejects invalid documents.

In `@frontend/src/pages/ProjectSettings.jsx`:
- Around line 926-938: The addDomain function currently only trims and checks
duplicates; add a format check before pushing to domains by validating newDomain
(e.g., no spaces or URL schemes, must be a valid hostname with optional port).
In the addDomain flow (using newDomain, domains, handleUpdate, setNewDomain),
run a simple validation (for example a regex that allows letters/numbers,
dashes, dots and optional :port and requires at least one dot, or use URL
parsing to reject strings with protocols or slashes) and if invalid call
toast.error("Invalid domain format") and return; only then build updated and
call handleUpdate and setNewDomain. Ensure the validation rejects entries like
"not a domain" or "http://example.com" while allowing "example.com" and
"sub.example.com:8080".

In `@frontend/src/pages/Releases.jsx`:
- Around line 18-30: The fetch in the useEffect (function fetchReleases) should
be cancellable: create an AbortController, pass its signal into the axios.get
call (or an axios CancelToken if your axios version requires), and in the
cleanup return () => controller.abort(); also guard calls to setReleases and
setLoading by checking for controller.signal.aborted (or catch the AbortError)
so you don't call setReleases/setLoading after unmount; update references to
useEffect, fetchReleases, setReleases, setLoading and the axios.get invocation
accordingly.
- Around line 123-128: Replace hardcoded colors in the markdown styles with CSS
variables to ensure consistent theming: update selectors like .markdown-content
h1, .markdown-content h2, .markdown-content h3 and other occurrences at the
noted ranges (e.g., the rules around lines 154-156 and 173) to use variables
such as var(--color-text) instead of `#fff`, var(--color-bg-tertiary) instead of
`#1e1e1e`, and use rgba() via a CSS variable with alpha (e.g.,
rgba(var(--color-text-rgb), 0.8)) or a dedicated translucent variable instead of
hardcoded rgba(...) so all themeable colors come from CSS variables.

Inline comments:
In `@backend/app.js`:
- Line 92: The releases routes are mounted without authentication
(app.use('/api/releases', releaseRoute)), so createRelease in
release.controller.js assumes req.user exists and throws; update the routes in
releases.js to apply the imported auth/authorization middleware to the POST '/'
endpoint (or to the router globally) so that req.user is populated before
createRelease runs; ensure the middleware symbol used (e.g., authMiddleware or
authorization) is the same one imported in releases.js and that the POST route
points to the createRelease controller.
- Around line 19-21: The app currently requires('./queues/emailQueue') at
startup which creates an IORedis connection synchronously and can throw if Redis
is down; change the initialization so the Redis client in emailQueue.js is
created with proper error handling or lazily initialized: add a top-level
.on('error', handler) and .on('connect'/'ready') handlers to the IORedis client
inside emailQueue.js, and wrap the initial connection attempt in a try/catch or
export an async init function (e.g., initEmailQueue) that backend/app.js can
call after the Express server binds, falling back to degraded behavior if the
connection fails; ensure any unhandled errors are caught and logged via your
logger instead of letting the require crash the process.

In `@frontend/src/pages/LandingPage/index.jsx`:
- Line 468: The Link element with className "btn-hero-secondary" currently has
text "Back to Console" but navigates to "/login"; update this to be consistent
by either changing the to prop on that Link to "/dashboard" if it should return
authenticated users to the console (update any conditional routing if needed),
or change the visible text to "Sign In" if it should send unauthenticated users
to the login page; locate the Link in LandingPage (the element with className
"btn-hero-secondary" and inline padding style) and apply the appropriate change.

In `@frontend/src/pages/LandingPage/style.css`:
- Line 5: Remove the unnecessary quotes around the Inter font-name in the
font-family declaration in LandingPage's stylesheet: locate the font-family line
(font-family: 'Inter', -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto,
sans-serif;) and change 'Inter' to Inter (no quotes) so it complies with the
stylelint font-family-name-quotes rule while keeping the remaining fallbacks
intact.

Outside diff comments:
In `@frontend/src/pages/LandingPage/index.jsx`:
- Around line 385-386: In the LandingPage component update the paragraph text
that currently reads "Link your supabase buckets or Supabase Storage..." to use
the intended storage providers string (e.g., "Link your S3 buckets or Supabase
Storage..."); locate the JSX paragraph in
frontend/src/pages/LandingPage/index.jsx (the <p> element with inline styles
around line 385) and replace the redundant "supabase buckets" phrasing with "S3
buckets" so the copy correctly reflects BYO Storage options.
- Line 122: The inline style in the LandingPage JSX uses window.innerWidth to
toggle display for the element with className "nav-links", which won't update on
viewport resize; remove the inline style and rely on the existing CSS media
queries (styles for .nav-links and .mobile-menu-btn) or implement a responsive
state with a resize listener in the LandingPage component: either delete the
style prop on the element that contains className "nav-links" so CSS controls
visibility, or add a useState (e.g., isMobile) and window resize handler in the
LandingPage component to update that state and conditionally render/assign a CSS
class instead of using window.innerWidth directly.
- Around line 136-140: The JSX is using window.innerWidth inline to decide
visibility for the Link elements and the mobile menu button (the Link
to="/login", Link to="/signup" and the button with className "mobile-menu-btn"
and onClick calling setIsMobileMenuOpen), which only evaluates once; remove
these inline window.innerWidth checks and instead control visibility via CSS
media queries or responsive classes (e.g., add distinct classNames like
"desktop-only" and "mobile-only" to the Login/Start Free Links and the
mobile-menu-btn) and update the stylesheet to show/hide .desktop-only and
.mobile-only at the desired breakpoints so the UI responds to window resizes.
