+### Done this session
+- [x] Round page crash (hooks violation + vite chunk split) — PR #85
+- [x] Playground redesign: Problem Explorer, auto-load spec, dynamic sample output — PR #86
+- [x] SOTA code surfaced on problem detail — PR #86
+- [x] `[easy]` stripped from h1 — PR #86
+- [x] Rankings "0.0=best / 1.0=worst" clarity — PR #86
+- [x] SpecDiagram arrow marker ID collision — PR #86
+- [x] Material tooltips (density + key property) — PR #86
+- [x] Load shows N + kg equivalent — PR #86
+- [x] SpecDiagram build volume dims: `190×90mm build vol.` label, `←78mm arm→` — PR #88
+- [x] Rankings: scoring formula deduped, `active specs` → `active problems`, #1 agent always green — PR #88
+- [x] WebGL crash (headless/no-GPU): `StepViewerBoundary` catches and falls back to SpecDiagram — PR #88
+- [x] `/guide` and `/playground` routes now set correct `document.title` — PR #88

+### P1 — remaining high-impact
+- [ ] **Terminology "spec" still used in Guide** — guide uses "spec" ~24× vs "problem" 1×; CLI commands use `--spec` (correct). Guide intro should define the distinction: "spec" = the technical JSON; "problem" = what you're competing on. Currently undefined.
+- [ ] **Category icons unexplained** — `⊕` for Stiffness/Weight is opaque. Either add a tooltip on hover explaining "Stiffness-to-weight ratio: N·mm per gram", or replace with a clearer symbol.
+- [ ] **"open" vs "unclaimed" inconsistency** — sidebar shows "open", category page shows "unclaimed". Pick one: "open" is better UX ("open" implies you can claim it), "unclaimed" is used in the API filter. Use "open" in UI everywhere.
+- [ ] **Unentered spec score tooltip** — `each scores 1.0` label on agent detail has tooltip but no visual indicator it's hoverable; newcomers miss it.
+- [ ] **Guide on mobile** — TOC is `hidden lg:block`; sub-1024px users get a flat wall of text with no jump navigation. Make TOC available at smaller breakpoints or add a collapsible mobile menu.
+
+### P2 — polish
+- [ ] **SOTA chart y-axis label** — values show cleanly but no axis title ("mass (g)", "stiffness (N/mm·g)", etc.)
+- [ ] **`1 agent competing` hero stat** — reframe empty state as opportunity ("42 problems up for grabs")
+- [ ] **Pill badges on home look clickable** — "Gittensor SN74", "Open Competition" → de-emphasize so they don't compete with CTA buttons
+- [ ] **SF badge tooltip on spec header** — `SF 1.5×` badge has no tooltip explaining "Safety factor: yield / SF = allowable stress"
+- [ ] **`sotaMass` param name in SpecCard** — stale for non-mass specs; rename to `sotaScore`
