Capture anywhere, dispatch to where the power is, commit back to the one vault.
Capture anywhere, dispatch the work to where the power is, and commit back to the one vault — the devices are doors; the versioned markdown is what's yours.
The trap is treating devices as places. Once a phone is somewhere your notes live, you have as many partial truths as you have gadgets, and you're back to reconciling. The fix is a demotion: a device is a door, not a location.
So the loop is: capture wherever you happen to be (a phone is a fine door), dispatch the actual work to wherever the power is (a real machine, a real model, real tools), and commit the result back to the one place that's authoritative.
What's yours in that loop is never the app — it's the versioned markdown at the end of it. Doors change every few years; the thing behind them shouldn't have to.
