Inline comments:
In `@apps/web/components/ChallengeBoard.tsx`:
- Around line 89-99: Filter out challenges with state "hidden" before the
grouping loop in ChallengeBoard, and use that filtered collection for both
category grouping and the board count. Preserve all non-hidden challenges and
the existing category ordering and modal behavior.
In `@apps/web/components/EnrollmentControls.tsx`:
- Around line 10-13: Replace the local EnrollmentResponse in
EnrollmentControls.tsx with the shared enrollment operation response type or
typed client method from `@openrange/contracts`, ensuring successful mutations
always provide the state needed by the parent UI. Update apps/web/README.md
lines 56-58 to remove or revise the “web app casts nothing” claim until all
client calls use shared response contracts.
In `@apps/web/components/LearnCatalog.tsx`:
- Around line 112-133: In the path mapping around the enrolled-state logic, bind
path.enrollment_state to a local constant, use that constant for the
null/undefined check, and replace the STATE_VARIANT and STATE_LABEL lookups’
casts with the narrowed constant. Update the later enrolled-state check to use
state !== null while preserving the existing rendering behavior.
In `@apps/web/components/Markdown.tsx`:
- Around line 15-26: Update the anchor renderer a in the Markdown component to
apply target="_blank" and rel="noopener noreferrer" only when href is an
absolute http:// or https:// URL; leave those attributes unset for relative
links while preserving react-markdown’s href handling.
In `@apps/web/components/ModuleReader.tsx`:
- Around line 341-357: Hoist the quiz-block filtering out of the
section.blocks.map callback in ModuleReader, computing the quizzes list once per
section; use that shared list to render QuizBlockForm only at the first quiz
block while preserving the existing rendering of non-quiz blocks.
- Around line 121-151: Reset lang to the default language and clear
availableLangs whenever moduleSlug changes, before probing the new module.
Update the useEffect associated with moduleSlug while preserving its
cancellation and probing behavior, so reused ModuleReader instances cannot
retain language state from the previous module.
- Around line 126-151: Update the language-probing logic in the ModuleReader
useEffect and its probe function so it does not rely on the API’s ignored lang
query parameter or HEAD requests; validate the requested language through the
supported response data before adding candidate.code to available languages,
preventing false positives such as Hungarian and avoiding unnecessary
full-payload probes.
In `@apps/web/components/PathOutline.tsx`:
- Around line 133-140: Update the totalSections and doneSections calculations in
PathOutline so sections are counted only when both the section and its parent
module are non-optional branches; preserve the completed check for doneSections.
In `@apps/web/components/QuizBlockForm.tsx`:
- Around line 41-58: Update submit in QuizBlockForm to clear the existing result
at the start of every new attempt, alongside resetting the error, so failed
submissions cannot display stale success text or per-question verdicts.
In `@apps/web/components/TerminalClient.tsx`:
- Around line 152-172: In the socket.onmessage control-frame parser, remove the
redundant control instanceof Object check and use a narrow type guard based on
the existing non-null object and session_id string checks, preserving the
current session ID assignment and open-status behavior.
- Around line 100-107: Update connect to detach the previous socket’s event
handlers before closing it, then guard the new socket’s close handler so it only
updates socketRef and connection status if that socket is still current;
preserve normal cleanup for the active socket and prevent superseded sockets
from clearing the replacement connection.
In `@packages/contracts/src/index.ts`:
- Around line 434-446: Extract the duplicated JSON request logic from postJson
and putJson into a private sendJson helper that accepts the HTTP method, path,
body, and any method-specific options. Have both methods delegate to sendJson
while preserving their existing CSRF-token handling, headers, serialization,
request invocation, and typed response parsing.
- Around line 340-381: Update postJson and its request flow so the declared
options.okStatus is actually enforced when provided, including the
expected-status check for 201 or 202 responses; otherwise remove the unused
option from the API and related callers. Anchor the change to postJson and
request, preserving existing behavior for callers that do not specify an
expected status.

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
Narrow enrollment_state with a local constant instead of two as casts.
Line 113 already proves the value is a real EnrollmentState, but the boolean does not narrow the property for the compiler, so Lines 128-129 need casts. Bind the value to a local constant and check the constant. The casts disappear and the lookups stay type-checked.

react-markdown 10 defaultUrlTransform javascript: protocol sanitization
💡 Result:
In react-markdown version 10, the defaultUrlTransform function is responsible for URL sanitization [1][2]. It is designed to be secure by default by preventing malicious protocols, such as javascript:, from being used in links [2][3]. The defaultUrlTransform function operates by allowing only a specific list of protocols: http, https, irc, ircs, mailto, and xmpp [2][3]. It also permits relative URLs (which do not start with a protocol) [2][3]. Any URL that does not match these criteria is typically neutralized, often by being replaced with an empty string, to prevent cross-site scripting (XSS) vectors [2][3]. Key points regarding URL sanitization in react-markdown: * Security Warning: Overwriting the urlTransform option with a custom function that does not include equivalent sanitization logic will expose your application to XSS vulnerabilities [1][4]. * Extension: As of mid-2026, a createUrlTransform factory is available to help developers create custom URL transforms that extend the default safe protocols (e.g., to add tel:) without having to reimplement the entire sanitization logic manually [5]. * Recommendation: To ensure content is fully safe—especially when processing untrusted input—it is recommended to use rehype-sanitize, which allows you to define a comprehensive schema of allowed elements and attributes [1][2][4].

react-markdown v10.1.0 source defaultUrlTransform transform href components a
💡 Result:
In react-markdown v10.1.0, defaultUrlTransform and the urlTransform option are used to safely process and transform URLs (such as the href attribute in tags or the src attribute in tags) to prevent security risks like XSS [1][2][3]. defaultUrlTransform The defaultUrlTransform function is the built-in, default behavior for the urlTransform option [1][4]. It ensures that URLs are safe by allowing only specific, trusted protocols: http, https, irc, ircs, mailto, and xmpp [2][5][6]. It also permits URLs relative to the current protocol, such as /something [2][6]. urlTransform Option You can override this default behavior by providing a custom function to the urlTransform property on the component [4][6]. This function receives three arguments [1][5]: 1. url (string): The URL to transform. 2. key (string): The property name being processed (e.g., 'href' for links, 'src' for images). 3. node (Element from hast): The underlying HAST element being processed. The function should return a string (the transformed URL) or undefined if no transformation is desired [1][2]. Custom Components for tags If you wish to customize the rendering of links specifically, you can use the components prop on the component [7][8]. By mapping the 'a' key to a custom React component, you can intercept the link rendering entirely: <Markdown components={{ a: ({ href, children,...props }) => ( <a href={href} {...props} target="_blank" rel="noopener noreferrer"> {children} ) }} > {'Link'} While urlTransform is focused specifically on sanitizing and modifying the URL string itself before rendering, the components prop provides full control over the resulting React element's attributes and structure [1][8].

Reset lang and availableLangs when moduleSlug changes.
If the component instance is reused, stale language state can request the new module with ?lang=hu and show “This module does not exist.” Current module links originate from PathOutline, but the reset keeps component state consistent for any same-route navigation.

Detach the handlers of the previous socket before you close it.
connect closes the existing socket at Line 105, but the socket keeps its onclose handler. The close event fires asynchronously, after Line 187 has already stored the new socket in socketRef. The stale handler then sets socketRef.current = null and sets the status to closed. After that, terminal.onData cannot send input, the Disconnect button does nothing, and the UI reports "Disconnected" while the new socket is open. The Reconnect button triggers this path whenever a session is already open.
Clear the handlers on the old socket, and guard the new handler against a superseded socket.

Remove the redundant type checks in the control-frame parser.
control instanceof Object at Line 161 adds nothing after the typeof control === 'object' and null checks. A narrow type guard makes the intent clearer.

Enforce or remove okStatus in postJson. postJson declares options.okStatus, but never reads it. request accepts every response.ok status, including 201 and 202.

Share one JSON-mutation helper between postJson and putJson.
putJson repeats the header build, CSRF attach, body serialization, and parse steps of postJson (Lines 399-422). Only the method and the CSRF-extraction step differ. Extract a private sendJson(method, path, body, options) and let both call it. This keeps future changes, for example a shared accept header or retry policy, in one place.
