Twenty PRs in one day, across three products

May 31 was a full-throttle day across Trim, AutoBrief, and TarmacLabs. Twenty merged PRs. Playwright E2E in Trim. Predictive compliance calendar in AutoBrief. A decimal-versioning system so the changelog reads like a living product, not a list of commits.

Some days you ship one feature and spend the rest of the afternoon writing about it. Today was not that day. Three products, twenty merged PRs, and a structural change to how we track progress publicly.

The numbers

Trim: Phase 0 infra (CI smoke against cfitrim.com, /admin/beta-status cohort dashboard), a 124-test unit-coverage sprint across the business-logic layer, Playwright E2E testing the auth gates, activation-funnel instrumentation, a founder reactivation endpoint, a security fix (unauthenticated notify kind), a Resend-key quoting bug fix, and the TS 6.0 parity bump. Seven PRs covering testing, observability, and hardening.

AutoBrief:went from a working v1 to something that starts to feel like a real dispatcher's tool — predictive compliance calendar, fleet risk score, override analytics, squawk logger, aircraft countdowns, handoff checks, expiration alerts, solo-endorsement tracking, FIRC currency, dispatcher notes, guest-pilot checks, Blue Sky Aviation sample school, and a waitlist Resend sync. Thirteen PRs in one day.

TarmacLabs:the admin data dashboard (the one that reads zero), the living-docs CI gate, and this post you're reading.

Decimal versioning

The changelog at /changelog now carries version badges on every entry — v1.0 for launch arcs, v1.1 / v1.2/ etc. for incremental upgrades. The purpose isn't semantic-versioning compliance — it's making the rate of iteration visible. A visitor scrolling the changelog should be able to see at a glance that the products are moving, not just that we wrote some entries.

Trim is at v2.4 (Playwright E2E). AutoBrief is at v1.6 (predictive compliance calendar). TarmacLabs site is at v4.2 (admin data dashboard). Each decimal is a shipped, verified PR — not a marketing number.

Ship rate is the only vanity metric worth tracking. Everything else follows from it.
