  1. expH: validation ladder closes + first atlas entries + Publications tab
    …
    expH (validation 2016-2021, opened once; holdout stays sealed):
- negative finding REPLICATES: 0 net survivors at full half-spread OOS
- CKX fails pre-registered sub-period clause (kappa* 0.445->0.263)
- ES->SPY flips sign OOS (+0.003, p=0.68) — regime-fragile
- daily reversal family: VR30 excess -0.143 -> +0.023 (crisis-regime)
- figure: alphas collapse OOS, the SPX staleness artifact persists

Atlas (via new_finding.py, Level 2 each):
- F001 nothing in the searched universe survives the full ladder
- F002 SPX->SPY lead is index content staleness (Fisher), survives SPA

Publications: new tab + P001 'The Artifact Frontier, Part I' — formal
write-up of expA->expG with live {{figure:...}} tokens rendered from
committed results.json

  2. Web: server-rendered SVG figures from results.json (dataviz-validated)
    …
    - web/lib/charts.js: expB staleness scatters, expC VR30-excess strip plot
  (FDR emphasis), expD raw-vs-fresh dumbbells; palette validated
  (validate_palette.js all-pairs PASS on card surface), native tooltips,
  ink-token text, selective direct labels
- figures injected on experiment pages + latest figure on home
- rendered and eyeballed (rsvg): fixed tick-label collision

  3. Web platform v2: editorial redesign, mobile-first + CSS-only menu, comments, SVG logo
    …
    - style.css rewritten: Fraunces/Inter/JetBrains Mono, warm paper palette,
  responsive grids, overflow-safe tables/code, light hljs theme
- CSS-only hamburger menu <=820px (opaque panel, no backdrop-filter)
- /comments: public guestbook — honeypot + 30s/IP throttle + HTML escaping,
  storage in ~/.anomaly-atlas/comments.json (survives rsync --delete)
- logo.svg: atlas graticule + data line + circled outlier; favicon + brand
