Work breakdown — W25
The dominant category this week (as consistently throughout 2026) is Healthcare AI platform at 69% of net output — clinical workflow automation, note generation, and operational tooling across the Phiniti / Ambient Scribe platform. Mobile and desktop surfaces (21%) reflect ongoing cross-platform work bringing AI capabilities to clinicians in their existing workflows.
The site and go-to-market work shipped this week (PRs #19 and #20) falls under the Go-to-market systems bucket (4%) — the agentic economics article and the production cost visualizations are proof assets, not just content.
What this week signals
141 commits across 12 active repos in a partial week, while also shipping two production-quality features and a full velocity refresh. The -62% WoW net-line delta is expected: W24 was a 384-commit week with large refactors; W25 is feature-focused, smaller changesets, higher-signal output. The exponential trend line on the velocity chart still points up.
This is what a 100x engineer actually looks like in the data — not a month-over-month straight line, but a portfolio of sustained throughput with executive judgment baked in.
