Async-first standups — Wednesday written status, no daily sync.\n2. Morning deep work — calendar protected 9–11am, meetings pushed past 10.\n3. Linear as system-of-record — verbal commitments she hasn't written into Linear are treated as not real.\n\nShe also pushes back hard on cross-team meetings without a clear decision owner.",

Async-first communication — explicit preference for written status (Wednesday Linear updates) over standups; she's said \"if it's not in Linear it isn't real\" in three separate threads.\n2. Protected morning deep-work — calendar is blocked 9–11am every weekday; she'll move meetings rather than break the block.\n3. Decision-owner gating — she refuses cross-team meetings without a named decision owner; this has come up six times since March.\n\nTension to flag: Alice's async-default occasionally collides with newer hires who prefer synchronous onboarding. She's aware of this — last month she experimented with a weekly 30-min office hour — but the data is too thin to call it resolved.",
