[Devin-AXIS]

What changed

• add a Star History section near the end of all four README variants
• render responsive light and dark SVG charts from privacy-preserving daily star totals
• update the chart every day on the dedicated star-history branch
• link the chart to the requested interactive Star History page

Why

Star History's unauthenticated README SVG currently falls back to a GitHub API restriction notice. This keeps the chart dynamic without putting a GitHub token in the README or sending a credential to a third party.

Impact

The README shows an automatically refreshed growth chart. The updater stores only dates and aggregate star counts; it does not store stargazer identities. Generated chart commits stay off main.

Validation

• pnpm readme:zh-hant:check
• node --check scripts/update-star-history.mjs
• parsed .github/workflows/star-history.yml as YAML
• verified same-day/same-count runs are byte-for-byte idempotent
• verified next-day updates append one aggregate point and render valid light/dark SVG
• verified both public raw chart URLs return HTTP 200
• git diff --check
• node .codex/skills/ipollowork-maintainable-code/scripts/audit-changes.mjs

Runtime evidence is not applicable: this changes README presentation and repository automation, not the iPolloWork application runtime.
