The Flight Log — learnings in public
Signal
Hundreds of sessions and decisions lived in private corpus while the portfolio only showed a company page.
Wrong turn
Publish raw chat or leave learning invisible.
Correction
Pruned Flight Log cards derived from decisions, principles, incidents, and deploys — public on businessadjacent.com/work.
SpaceX and Tesla do not publish every private thread. They publish structured learning: route, failure, correction, proof.
This card is recursive on purpose. The Flight Log is both the portfolio instrument and an internal navigation aid — LOCK, PRUNE, COURSE, SHIP — so future sessions stop re-deriving settled truth and start from the route already flown.
Cadence: zero to three cards per real work session. Quality over volume. Redaction before publish.
