2026-06-17 11:01 UTCMilestone 2 delivered over 2 pass(es): 129 credits, 1 artifact(s)
2026-06-17 11:01 UTCRebuilt `index.html` as a complete single-file Pomodoro app with inline semantic HTML, responsive CSS, and vanilla JavaScript. It now includes accurate 25-minute work and 5-minute break countdowns, Start/Pause/Reset controls, automatic alternation, completed work-session counting, MM:SS display, and browser tab title updates at each session transition. No external dependencies or SDKs are used; the only APIs to sanity-check in a browser are standard Web APIs such as `document`, `Date.now`, `window.setInterval`, and `window.clearInterval`.
2026-06-17 11:01 UTCIntegration review passed across 1 file(s): The single-file HTML/CSS/JS deliverable runs directly in a browser with no missing dependencies or broken local references..

2026-06-17 10:49 UTCPostmortem (milestone 2): The previous build did not deliver any files, so there was no timer to review or test.
