feat: v0.13 Sprint summary

[hazeliscoding]

The v0.13 milestone from ROADMAP.md: the board opens with how the sprint is going, and turns that into a standup you can paste into Slack or Teams in one click. This stays a draft until the milestone's "Done when" holds.

Decisions (2026-09-29)

• The health strip tells the sprint's story: days left, open, needs attention, merged and median time to merge, each with a one-line note. Per-status counts stay in the table headings.
• Sprint numbers are the team's. Author chips, search and snoozes never change the strip or the standup. They only shape the tables and the Sweep.
• Each open PR appears once in the standup, in its most urgent group: Blocked, Needs attention, then In review. Merged since the last working day comes first. Drafts stay out.
• Lines name the author's login as plain text, with no @mention and no per-person counts.
• Copy standup writes rich text and Markdown together, so Slack and Teams paste it formatted with PR links, and plain-text places get Markdown.
• Markdown links are written [ref](<url>), so Discord doesn't stack a preview card per link. The formatted version writes non-ASCII characters as HTML entities.
• One click, no preview. The button says what it copied, and only appears when the board's period includes today.
• The sprint-end line moves from the Sweep header into the strip.
• No new GitHub fields, so sweep time is unchanged. The sweep result's schema goes to 6, so the first refresh after updating is a full one.

Progress

• Roadmap, AGENTS.md and this pull request
• Paste test in Teams and Discord (Slack skipped)
• core/summary.ts with tests
• Health strip: the sprint's story
• core/standup.ts with tests
• Copy standup
• Screenshots, README, keyboard pass, bundle size
• Release

What changed

• Health strip: days left, open (and not yet approved), needs attention (and how much is blocked), merged (and since yesterday), and median time to merge. Always the whole team.
• Copy standup at the end of the strip. The confirmation line says what it copied.
• The Sweep header no longer has the sprint-end line; it's in the strip now.
• Under the hood: core/summary.ts and core/standup.ts in main, with tests. The grouping rule is standupGroup in the attention engine. The sweep result's schema is 6, so the first refresh after updating is a full one. No new GitHub fields, so sweeps take as long as before.
• Renderer size: 988.5 KB, 1.6 KB more than v0.12.

Screenshots

The board states that changed, shot with node e2e/screenshot.mjs --fixtures. All 30 are on the pr-assets branch under v0.13/.

Testing

Build, unit tests and design checks

npm install
npm run build
npm test
npm run check

• Eleven … pass lines, including summary and standup.
• npm run check ends with contrast: 63 pairs pass AA in both themes and assets: no remote URLs, stray fonts or raw colors.

Fixture screenshots (no token, no network)

cd desktop
node e2e/screenshot.mjs --fixtures

• desktop/e2e/shots/ holds 30 images, including busy-standup. Your clipboard is untouched: the script stubs it.

On your own account (classic token)

• First refresh after updating is a full one (the cache format changed), then the strip fills in.
• The strip reads right: days left and the end date, open and not approved, needs attention with how many are blocked, merged and how many since yesterday, and the median time to merge.
• Team-wide: pick an author chip, type in search, snooze a row. No number in the strip changes, while the tables and the Sweep do.
• Needs attention matches the Sweep's count before you snooze anything.
• Copy standup, then paste into Teams: bold headings, PR links, bullet lists, and now a gap between the title and the first group.
• Paste into Discord: Markdown with working links and no preview cards.
• The standup agrees with the strip: Blocked plus Needs attention equals the strip's Needs attention, and "Merged since …" matches the Merged note.
• Only for today: step to next sprint and Copy standup disappears; Current brings it back.
• Keyboard: Tab reaches Copy standup right after the top bar, and Enter copies.

Paste test (done before building)

• Teams: bold headings, bullet lists and PR links survive; a title's Markdown and HTML characters show as typed; one preview card for the first link, removable with its ×.
• Discord: takes the Markdown version; no preview cards once links are [ref](<url>).
• Slack: not tested. It gets the same formatted version as Teams.
