Version 0.6.0, with one consolidated CHANGELOG entry, the two brief changes, and the Sundown example.

In this PR

• Version: 0.6.0 in pyproject.toml and chartwright/__init__.py.
• CHANGELOG: the per-PR "Unreleased" sections are now one 0.6.0 (2026-10-05) entry, with Added, Changed and Fixed, and exact duplicates removed.
  • "Upgrading from 0.5" is new. It lists the fields 0.5 refuses, and the warn-level rules added since design brain 7. That list was read from the rule registry, not written from memory.
  • Intermediate design brain numbers (8 to 16) are gone; only 7 → 17 is stated.
• Brief:
  • Titles are recommended to name the measure, unit and window; a number belongs in a title only when the spec computes it from data. This replaces "Titles state the answer ('Orders fell 12% WoW')", which goes stale at the next refresh.
  • Colour by role is recommended (an accent for chrome, this period against last as a hue and its tint, status beside an arrow or a word). This replaces "Superset's default palette".
  • All three briefs stay within 150 lines.
• Skill: it offers those two styles to the user as recommendations before writing a spec, and a style the user asks for wins. It also fixes step 1, where a merge had spliced two versions of the chart-type sentence together.
• examples/sundown/: the README dashboard.
  • It ships sundown.json, build_spec_sundown.py with its facts.json, seven palettes (coral-teal-v2 by default) and theme/ (the Superset theme and a script that creates it).
  • The README states what it needs to run: the warehouse for apply, and Superset 6.0+ for the theme.
  • The new test_example_sundown.py checks that the shipped spec compiles, that the builder writes it byte for byte, and that every palette builds a valid spec.
• Docs:
  • The Design Brain's default.value-labels row is corrected for grouped bars.
  • examples/README.md no longer says the taxi spec is unedited; 0.6.0 added its axis titles.

Checks

• Offline: 2429 passed, 1 skipped. params_drift --all is clean, and the rule table is up to date.
• advise on the Sundown spec: 0 errors, 0 warnings.

Not done (noted)

• A small usability gap. An ignore for a tab-level finding needs the positional key (layout.fold-budget@tab-About-row-1); rule@TabName is ignored without a word. Logged for later.
• What's next: the tag, PyPI and the GitHub Release come after this merges (gate 3). README docs: the V10 README with the Sundown carousel, and eight guides #9 follows.
