The interactive claim/move buttons concatenated work-item ids into inline
onclick JS with only single-quote escaping — a crafted id (ids/titles come from
GitHub sync and manual upserts, not a strict allowlist) could break out and
inject script, even on the localhost-only server.
Fix: emit the id/lane in HTML-escaped data-* attributes (escapeHtml encodes
&<>"'), attach delegated click listeners that read them via getAttribute, and
pass the raw value as a JS string arg — never concatenated into code. Adds a
regression assertion that no inline onclick handlers with interpolated ids
remain. Flagged by automated security review.
Full suite 2845/2845; lint green.
