QuantPrep changelog

Intelligence in Motion

• Refined the anatomical brain with an emerald neural network, luminous hubs, fine internal particles and a controlled surrounding energy field.
• Replaced the earlier arcing motion with a predefined, smoothly damped scroll journey and subtle turns. Added staged particle formation, coherent dissolution and gentle pointer-responsive energy.
• Added depth-tested transparency, bounded mobile detail, matching static artwork and checks for timeline continuity, graphics cleanup and failed downloads.

A Prepared Mind — previous homepage foundation

• Rebuilt the homepage around an attributed, Blender-authored jade cortex with particle formation, scroll-linked poses, fine energy paths and final dispersal.
• Kept all headings, copy and actions as accessible HTML. The anonymous free-training flow and application remain intact.
• Added motion controls and static artwork for reduced motion, data saving or unavailable graphics. Phone artwork stays clear of reading and interaction areas.
• Added desktop/mobile browser resilience checks and separate mesh, poster and font budgets. Editable art source is excluded from the published website.

The Quant Path

• Rebuilt Home, Practice, Interview, Progress and Profile around a daily learning path with fresh mistake retrieval.
• Added strict interview reports, durable verbal notes and a quote-by-quote market simulator with transparent P&L accounting.
• Introduced a real homepage practice demo and original quantitative-trader, researcher, developer and topic guides.
• The audited bank now contains 222 named reasoning families, 1,888 registered generators and 72 verbal prompts. Numbered difficulty and range variants are grouped, not advertised as distinct pedagogical templates.
• Added 120,832 seeded generator executions per build, explicit mathematical invariants, browser tests and build budgets. These checks are not a claim of exhaustive independent mathematical review.
• Hardened account isolation, progress merging and owner-only analytics. Production accounts require configured Supabase migrations and Netlify functions.

Earlier release counts below are historical registered-generator counts, not directly comparable with the current family count.

The Living Roadmap

• Redesigned the 90-day course as a more expressive visual journey without changing progression or review logic.
• Added eight restrained chapter color identities, progress-drawing path spines and clearer current, completed, checkpoint, review and locked states.
• Added one-time viewport reveals for chapters, nodes and Interview Arena, with complete reduced-motion fallbacks.
• Improved roadmap depth, hierarchy, hover feedback and mobile legibility while preserving the sticky daily action rail.

Interview Coverage Audit

• Audited the bank against current official interview guidance and role material from leading quantitative employers, with first-hand reports used only as supporting evidence.
• Added 330 original generators across 33 missing archetype families, bringing the scored bank to 1,856 templates and 16 categories.
• Added confidence intervals, calibration, research validation, data modeling, linear algebra, algorithms, quote updates, inventory skew, execution costs and options-risk drills.
• Added 48 self-evaluated verbal prompts for live problem solving, behavioral evidence, research deep dives, coding explanation, trading judgment and case interviews.
• Added automated coverage gates and documented the evidence, limits and ongoing audit method.

The 90-Day Path

• Rebuilt the signed-in Home experience as an eight-chapter, 90-day visual learning path.
• Added next-day mistake retrieval: missed patterns return as fresh variants at the end of the following course session.
• Added expanding review intervals after successful retrieval, chapter checkpoints and timed pressure sets.
• Simplified signed-in navigation to Home, Train, Progress and Profile.
• Removed firm selection and firm-weighted question choice from both training experiences.
• Added an unlimited Interview Arena after Day 90 while retaining configurable independent practice throughout the course.

Production Readiness

• Added an explicit, verified Netlify build and functions configuration with a clean public output directory.
• Hardened Supabase sign-up, sign-in, magic-link, session refresh, progress sync and account deletion flows.
• Added privacy-conscious first-party event analytics without advertising cookies or persistent visitor identifiers.
• Added an owner-only analytics dashboard protected by Supabase authentication and a server-side email allowlist.
• Expanded technical SEO validation across canonical URLs, metadata, sitemap coverage, robots directives, structured data and legacy anchors.
• Added production health reporting, rate limits, security headers and a complete deployment checklist.

The Visual System

• Redesigned the complete product around a light institutional visual system with a controlled dark market-making workspace.
• Added a new QuantPrep analytical-path mark, favicon, PWA icons and purpose-built social preview.
• Rebuilt the homepage with progressive quantitative motion, real HTML product overlays, interactive roadmap and live parameterized-question demonstrations.
• Refined Today, roadmap, trainer, feedback, focus mode, reports, firms, applications, progress, onboarding and responsive navigation.
• Added shared light and dark theme tokens, reusable component primitives, reduced-motion behavior and mobile application cards.
• Preserved the complete 1,526-template engine, adaptive algorithms, account architecture, SEO content and public URL structure.

Zero to Quant Trader

• Added a local-first application shell with Today, roadmap, practice, review, mocks, firms, applications, progress and profile routes.
• Added quick and full diagnostics, evidence-weighted mastery, adaptive question selection and spaced review scheduling.
• Added meaningful-activity streaks, daily-plan generation, granular skill metadata and firm-weighted readiness.
• Added a working market-making simulator with two-sided quotes, size, changing fair value, flow, inventory, P&L and debriefs.
• Added optional Supabase authentication and sync architecture, secure database policies, data export and local deletion.
• Redesigned the public homepage and added an indexable public roadmap with topic pages.
• Preserved the complete 1,526-template question engine and connected the classic trainer to v14 progress tracking.

Professional and search foundation

• Added visible proof of 1,526 templates, 14 categories and 16 firm-style profiles.
• Added a transparent methodology, version banner and product-status messaging.
• Created crawlable guides for quant questions, preparation, mental math, probability and market making.
• Created firm preparation guides for Jane Street, Optiver, IMC, Citadel Securities and SIG.
• Added sitemap, robots instructions, canonical metadata, Open Graph assets, structured data, web app manifest and Netlify headers.
• Improved mobile navigation, footer architecture, accessibility and internal linking.

Question-bank expansion

• Expanded from 72 to 1,526 parameterized templates.
• Expanded from seven to fourteen categories.
• Added sixteen firm-style training profiles.
• Moved training to a dedicated mobile-friendly page.
• Added statistics, stochastic processes, options, market microstructure, game theory, estimation and sequence families.

Original single-page trainer

• Introduced Training and Interview modes, clocks, scoring and reports.
• Launched the original 72-generator bank.
