Development & release

Repository layout

• wintage.user.js — the userscript (Tampermonkey). Palettes are embedded by tools/apply-themes.js inside the THEMES registry.
• themes/*.json — the sixteen palette packs, the single source of truth for colour.
• desktop/ — the desktop theme subsystem: tools/build-desktop.js fills ${token} templates from the packs, install.ps1 installs into the user profile, WintageInstaller.ps1 is the WinForms GUI. Generated desktop/out/ is gitignored and rebuilt with node tools/build-desktop.js.
• tools/ — generators and gates: apply-themes.js, derive-palette.js, check-css.js, build-desktop.js, electron-fuses.js, inspect-electron.js (reads a live themed app over CDP), plus the test harnesses.
• browser-theme/ — companion Chromium theme manifests generated from a role-based template.
• tests/ — PowerShell test harness (Run-Tests.ps1).

Releasing a new version

Add a ## [x.y.z] - date entry to the top of CHANGELOG.md first — release.ps1 refuses to run without it. Then:

.\release.ps1 -Message "what changed"

It bumps the @version patch number (the Tampermonkey header and the W95_VERSION stamp both move together), rebuilds the generated desktop themes, runs the whole release-gate suite, and commits, tags, and pushes — Tampermonkey clients pick the update up automatically. Pass -Bump minor or -Bump major for bigger releases.

Gates

release.ps1 refuses to ship unless the generated artifacts are current:

• tools/build-desktop.js --check — desktop outputs match the packs.
• tools/check-css.js — no stray/unclosed/nested comments, brace imbalance, or off-palette hex in the CSS bodies; also checks the per-theme WCAG AA floor and version stamp consistency.
• tools/test-theme-packs.js, tools/test-repainter-polarity.js, tools/test-theme-switch.js — the behavioural harnesses gated into release.
• tools/test-shim-payloads.js, tools/test-terminal-font.js — the Electron shim payloads parse, and the terminal colour table stays console-consistent.
• tools/check-wiki-mirror.js — the repository wiki/ mirror matches the maintained wiki source.

Deliberate deviations from UI.md

Transition/animation stay at 0.001s (live evidence beats the literal law); no global margin: 0 or box-sizing; no body { overflow-x: hidden }; no class-name-based status colours; semantic tokens are never used as text colour (1.8:1 fails AA). Full reasoning lives in .saipen/KNOWLEDGE/ADR-001..006 in the source repo.
