From 76d8f259b23325e81c1dfcee16a77d0c62871587 Mon Sep 17 00:00:00 2001 From: Harwinder Sekhon Date: Thu, 10 Sep 2026 06:56:01 -0400 Subject: [PATCH] Move the course advisor into a floating panel and link courses in its prose MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The advisor was a card inside the home page, so reaching it meant navigating back to #/ and it was rebuilt on every render of that view. It is now a bubble in the bottom-right corner of every screen bar the player and a quiz, opening a chat panel that stays put as you move around — ask what to take next, follow a recommendation, keep asking. It is built once into #overlay-root, outside the view that gets replaced, and syncAdvisor() called from renderChrome() is the single path that decides whether it is on screen; that covers every route change and every loadMeta(), and makes the Settings toggle work with no change to its handler. Being permanent removes the reason for the routeSeq guards in ask(). An answer that arrived after the user navigated was written to sessionStorage and then dropped unrendered; now it lands, and the bubble carries an unread dot if the panel is closed. showAuth() wipes the transcript and hides the dock, both of which are new requirements: the dock is a sibling of #app-shell, so hiding the shell no longer hides the advisor, and the widget now outlives a sign-out. Courses named in the answer itself are links. advisorResolveCourses() is lifted out of advisorValidateRecommendations() so an id written inline goes through the same existence check and the same redirect to whichever duplicate copy the learner has progress on — a sentence and the card under it can never point at different copies. The map is keyed by the id as the model wrote it, since that is what the browser has to find in the text. The client splits the raw line before escaping rather than linkifying escaped output: esc() writes an apostrophe as ', and the course-id pattern matches the #39 inside it. Under 900px the panel is a full-height sheet, and the mobile toast strip lifts clear of the bubble only while the bubble is actually on screen. The z-index sits on the dock rather than #overlay-root, which would otherwise become a stacking context and trap the confirm dialog behind the panel. README's advisor section is brought back in line, including the parts left stale by 05f0abc about sections and the whole library going out per question.
