Thirty-two tasks. The highest task count in a single day so far. March 26 was a deployment hardening marathon: three full deployment readiness audits across 37 repositories, test suites added to six separate libraries and services, security fixes, port standardization, SDK upgrades, and an Electron desktop client feature integration. The day closed with a newsletter service getting transactional email support and a full email rendering pipeline.
The weighted average leverage factor was 24.2x. Significantly lower than recent days because three deployment readiness audits (178, 108, and 45 minutes of Claude time) dragged the average down. Those audits touched dozens of repositories each and involved real investigation time. The supervisory leverage factor was 168.8x, meaning every minute I spent writing prompts produced nearly three hours of human-equivalent output.

Analysis
The project management tool build (96x) topped the chart. A complete project hierarchy with Trello import, database migrations, API routes, frontend components, and documentation in a single 25-minute session. That pattern of well-scoped greenfield work consistently produces the highest factors.
The desktop client feature integration (80x) and OIDC auth client test suite (60x) rounded out the top three. Both share a common trait: clear interfaces and well-defined scope. When the boundaries are crisp, the AI moves fast.
The three deployment readiness audits tell the real story of the day. Scanning 37 repositories repeatedly, identifying issues, fixing them, and pushing changes is exactly the kind of cross-repository grunt work that resists parallelization for a human engineer. A human would spend half the time just switching contexts between repos and remembering where each one left off. The longest audit (178 minutes, 2.7x) was the most thorough: 44 issues found, 30+ fixed, 4700+ lines of tests added. That low leverage factor reflects genuine complexity, not inefficiency.
Test suite generation dominated the middle of the range. Six separate test suites totaling over 600 tests were added across UI components, console simulators, activity libraries, notification services, auth clients, and payment webhooks. Each suite was generated in a single session with full coverage of edge cases. This is the kind of work that is profoundly tedious for humans and where AI leverage is most consistent.
The supervisory leverage of 168.8x means that for every minute I spent writing prompts, I got back nearly three hours of engineering output. That ratio held despite this being a maintenance-heavy day rather than a greenfield day.
