…tion Navigation IA cleanup: math route consolidation and sidebar discoverability improvements across multiple sections. Math routing: - Add /math hub page (MathLandingView) linking to Refresh and Bridge - Add canonical routes /math/refresh and /math/bridge - Legacy /math-refresh and /math-bridge redirect with params preserved - Reference deep links untouched Sidebar wiring (Learning + Career): - Add Cognitive Toolkit and Behavioral Design to Learning section - Add Career Foundations to Career section - Extend Learning and Career header active states Sidebar wiring (Projects + Business): - Add OSS Projects and HF Projects to Projects section - Add Brand Studio and Execution Playbook to Business section - Extend parent header active states Section rename: - "Side Projects" → "Business" (label + aria only) Docs deep-dives: - Add 6 deep-dive sub-items under Docs > How It Works - Extend Docs header active state for deep-dive routes - Add mcp_ecosystem ViewId for /how-mcp-works - /how-gpu-works intentionally left in Reference
Separate Core (Ingest/Library/Chat) from Learning/Career/Projects/Organizer with a thin divider. Separate Mission Control from Reference/Personal/Business with a divider after Workspaces. Add Business section label for clarity.
Enhance MathLandingView to show inline navigation for Zero to One (6 topics) and Prepa ML (8 topics) as clickable pills that link directly to /math/refresh?track=...&tab=... No sidebar changes. Math Bridge card kept at bottom.
…ar collapse Backend: - Migration 0084: track_resources table, track_type on tracks, color on modules - Extend curriculum models, loader, store, and API for resource tracks - Resource tracks skip concept validation, support curated link collections - New endpoints: GET track resources, GET module resources - Seed job supports --type filter and skips _ prefixed files Data: - 11 resource track YAML files extracted from hardcoded frontend views - 569 resources across 79 modules seeded into database - Tracks: AI Engineering, Frontend Eng, GPU for AI, Embodied AI, Bio-Augmentation, Databases, Applied Systems, Interview Prep, Freelance Strategy, Cognitive Toolkit, Behavioral Design - Displaced prep resources saved in _prep-displaced.yaml for merging Frontend: - Generic TrackDetailView handles both concept and resource tracks - Resource tracks render with tabbed modules and ResourceCards - CurriculumTracksView shows both track types with correct metadata - Sidebar collapsed: removed entire Reference section (~1,300 lines) - Removed Lenses, Levels, Cognitive Toolkit, Behavioral Design from nav - Added Dev Reference nav item linking to existing dev-ref page - Added inline tab navigators to DevRefView and DomainOntologyView - Frontend types extended with TrackResource, track_type, color fields
Delete the entire math feature family: /math, /math/refresh, /math/bridge and legacy redirects /math-refresh, /math-bridge. Removes 22 math-only files (views, routes, components, hooks, data), cleans sidebar nav, route tree, ViewId entries, workflow inventory, command palette, reference sections, and landing page references. MathRenderer.tsx preserved (moved to components/) - still used by culture-generale and ConceptDetailView.
…ion fallback Curriculum YAML cleanup from product audit: - Track 1: remove remedial concepts (number, fraction), merge redundant concepts (sample-mean, deviation-from-mean, squared-error, l1-reg), add one-hot-encoding and normalization-scaling to Module 9 - Track 2: swap Retrieval before Ranking (pipeline order), remove feature-store (canonical home is Track 4), add embedding prerequisite - Track 3: remove etl-vs-elt (redundant with Track 4), merge alerting-thresholds and model-rollback into neighbors - Track 5: rename batch-vs-real-time-serving to match Track 3 naming Create 5 missing canonical concepts with minimal dossiers: embedding, bias-variance-tradeoff, one-hot-encoding, normalization-scaling, regularization Fix concept explanation fallback to be dossier-first: - Fetch dossier before attempting retrieval - Dossier-only concepts produce real explanations (no dead-end) - LLM fallback when neither dossier nor sources exist - Three explicit provenance modes in API and UI: dossier+retrieval, dossier_only, llm_fallback
Test fixture was using old schema (sort_order column, no track_type/ category/color). Updated to match current production tables. Also updated stale YAML assertions for ml-foundations (9 modules, not 3).
…e_concepts Fixes ruff F401 (unused `field` import) and E741 (ambiguous `l` variable).
