Tripwires and reminders
A future-dated email nudge to revisit a decision.
The exit plan (kill criteria)
Every slip includes a pre-registered exit plan — a short checklist of conditions under which you should abandon the winning option, decided now, before you've committed and before hindsight can rationalize sticking with a bad call. It also names one early warning / leading indicator — the signal you'd see first, before the kill criteria are fully triggered. This is the slip's answer to sunk-cost bias: the conditions for changing your mind are written down at the moment you're most objective, not renegotiated later.
The tripwire reminder email
Every completed run gets a review date — between 7 and 365 days out, chosen by the engine based on the decision (defaulting to 30 days if it doesn't specify one). If you provided an email when running the verdict (or you're signed in), solvemax emails you on that date with a link back to the slip and its exit plan, so the kill criteria actually get checked against reality instead of forgotten.
How delivery works (so it's actually reliable)
Reminder delivery does not depend solely on a scheduled cron job. Real site traffic itself triggers a check for due reminders (throttled to roughly once an hour), with the daily cron job as a backstop — so a reminder still goes out even if the scheduled job has an off day. Each reminder is claimed exactly once via a database-level compare-and-swap before sending, so even with two independent triggers checking at once, you're never emailed twice for the same slip.
What the reminder looks like
The email links straight back to your slip — headline, exit plan, and all — with no separate summary to keep in sync. Nothing is re-computed; you see exactly what the slip said the day it was made.
