BTC Future-Day Preservation Pass

Core heuristic: Today's route must preserve the remaining certified menu.

Procedure

1. Identify how the proposed route, completion, miss, extra segment, closure, access blocker, or route replacement changes the remaining official segment set.
2. Treat already-completed segments that remain physically necessary as official repeat mileage or connector context, not as new remaining credit.
3. Run or request recertification after meaningful state changes: proven completions, missed segments, extra covered segments, closures, route-list changes, access blockers, condition blockers, and route/parking edits.
4. Check remaining certified-calendar capacity, p75/p90 time windows, hard stops, heat windows, and bailout options.
5. Compare today's benefit against future-route damage. Preserve less-optimal backups when they keep the month feasible.
6. If a split is slower but improves bailout, water, heat, car access, or hard-stop fit, keep that value visible instead of rejecting it on speed alone.

Do Not Infer

• More official miles today is always better.
• A completed overlap means the later physical route disappears.
• A slower split is worse if it improves future logistics.
• Future capacity remains valid after closure, access, or completion state changes.
• Manual deletion from a future outing is enough without recertification.

Output

• Future status: preserved, needs_recertification, future_capacity_risk, blocked, or better_as_backup.
• Remaining official segment impact.
• Repeat/connector role for completed overlaps.
• Future day capacity and hard-stop risk.
• Recommended repair or scheduling change.
