+# Week 21 Recap — May 11–17, 2026
+
+Fifth week. The agents completed a full data-testid migration across all E2E specs, upgraded Lexical to 0.44.0, shipped workspace home improvements (image paste, import markdown, new database button), and added 116 new tests — while closing 47 issues.
+
+## Highlights
+
+- **E2E selectors are now fully data-testid based.** Five PRs migrated every remaining parent-traversal selector across workspace home, sidebar, members, favorites, trash, and database specs. This eliminates the selector fragility that caused 14 E2E bugs in prior weeks.
+- **Clipboard image paste works in the editor.** Users can paste images directly from the clipboard into any page. PR #1035.
+- **Workspace home gained three new actions.** Import Markdown, New Database button, and page type indicators make the home page more functional. PRs #1037, #1095, #1099.
+- **Lexical upgraded from 0.31.0 to 0.44.0** with no regressions. PR #1071.

+
+### Maintenance (Days 31–32)

+
+### Performance (Days 29–30)
+- **Shared base JS reduced** — 152 kB → 150 kB gzip. PR #1039.
+- **DB health endpoint latency reduced** — faster health check response. PR #1032.
+
+## What's Next
+
+- **Command palette (⌘+P)** — quick page switching by title, the most-requested navigation improvement. Issue #1107 (awaiting human approval).
+- **Bundle size reduction** — all 12 pages exceed the 200 kB budget after the Lexical upgrade. Issue #1121 (awaiting human approval).
+- **DB latency investigation** — health endpoint latency has exceeded 500ms for two consecutive weeks. Issue #1123 (awaiting human approval).
+
+## Challenges & Learnings
+
+- **CI pass rate dropped to 93.2% from 100% last week.** May 13 had a 77.8% pass rate (4 failures out of 18 runs), likely related to the Lexical upgrade and data-testid migration landing on the same day. The failures were transient — all resolved without code changes — but the overlap of a major dependency upgrade with a broad selector migration created a rough day.
+- **Four open issues are all blocked on human approval.** The automation system correctly gates high-risk changes (browser print override, bundle restructuring, infrastructure investigation, cross-browser CI) behind human review. The backlog is otherwise empty, so the agents are effectively idle until these are unblocked.
