CodeEraser 0.4.0

v0.4.0 — the structure screen grows a tree, and axis 3 lands where it lives

GUI

• Structure tree lens (map | tree switch, persisted): an indented
  directory tree over the SAME report the treemap renders. Each row rolls
  its subtree's findings into a heat rail (log-ranked against the report's
  own range), carries an own-findings chip, subtree/files columns under a
  sticky header, and inline axis tags — the count becomes the answer.
  Unary chains fold exactly like the treemap's strips; selection and the
  detail aside stay shared across both lenses.
• Squarified treemap (Bruls et al. 2000) replaces the slice-and-dice
  layout: tiles approach unit aspect, unary chains collapse to one strip,
  labels middle-truncate, and a paint-order halo keeps text legible on the
  hot end of the ramp.
• Three-screen polish round: brand header, alarm-ramp legend, score bar,
  chips-based summary, trend endpoint marker, candidate magnitude bars,
  language toggle fixes, and a window floor of 860×560.

Judgment core

• Axis 3 (misplaced) now reports its directories: findings carried
  no axis-3 rows even though the axes strip counted them — on this
  repository, 42 misplaced-file violations (46% of the judged total) were
  invisible to both GUI lenses and to the report's per-directory face.
  One predicate now feeds both faces (count + deduped dir list); the
  structure golden and the hand-computed test assertions moved with it.

Guard / reports

• The Stop audit closes its untracked blind spot: git diff HEAD
  cannot see a brand-new file, exactly what a probe-bypassing shell write
  leaves behind. The stop path now merges ls-files --others --exclude-standard (binaries count 0 lines, .ce/ skipped);
  ce precommit stays staged-only by design.
• ce graph --sites --format json carries a schema id
  (ce.sites-report/0.1.0) — the last bare-JSON face among the eleven
  report families.

Site & docs

• codeeraser.dev: showcase screenshots (treemap, tree, candidates), an
  architecture SVG shared by the README and both site pages, narrow-screen
  overflow fixes (one min() sweep), and stylesheet cache-busting so a
  deploy reaches returning visitors immediately.
• README (en/zh): hero screenshot, architecture diagram, tightened
  install section.

CI

• The ubuntu apt step gets real armor: a pinned mirrorlist, per-try
  timeouts, three attempts, and a 15-minute step budget — measured at
  23s on a healthy day instead of a six-hour black hole on a bad one.

Full test surface for this train: 54-case end-to-end matrix (all report
families, ratchet lifecycle, guard modes, daemon + MCP, installed-binary
resolution), core golden suite, cli integration suite, and the dogfood
gate this repository runs on itself every push.
