Integration — The Personal Operating System

Synthesize everything into a single compact document — your Personal Operating System — that codifies how you intend to operate: protocols, defaults, calibrations, refusals, commitments. Re-read your M0 diagnostic beside it. Run the OS for a month, log defections, ship v1.1. Then keep it alive: quarterly re-reads, annual revisions, for the rest of your career. The OS is the Gemfile + lockfile + CI config of your working life: the explicit defaults everything else runs against. An app's behavior is determined more by its config than by any single line of code; so is a career. Engineers who would never run an app without a Gemfile run their lives without the equivalent. The capstone is the integration test. Thirteen modules produced unit-tested components; components passing in isolation do not guarantee the system works. The month-long run is the integration test, the defection log is the test report, v1.1 is the bug-fix release. The OS is versioned — and pinning it forever is as fragile as never updating a lockfile. The annual revision is bundle update for the self. And the hardest discipline is deletion. The 400-600-word target exists because the first draft will be 2,000, and the best PRs delete more than they add. A long OS is a non-functional OS; the length itself is the failure mode. The deletion is where the value is.
