# Atlas / the dispatch gap.

Fictional practice records — no customer incident.

A shipping backlog review across two team timezones. The room separates the three-hour impact window from preparatory notes and preserves the unconfirmed scanner report.

## Reviewed milestone intervals

- Impact to detection: 12m
- Detection to mitigation: 78m
- Impact to resolution: 3h

Intervals are computed from the explicitly selected event IDs. Reported timestamps remain reported; chronological proximity does not establish causation.

## Cause statement — hypothesis

The scanner handoff may have stopped propagating dispatch acknowledgements. The local records do not establish a device or vendor fault.

## Owned follow-ups

- **Verify the scanner handoff path** — Ari / operations; due 2026-10-16; open; event atlas-05
  Acceptance: Record a controlled check with before/after evidence. Review the working hypothesis before changing production.
- **Update the detection and handoff checklist** — Sam / shift lead; due 2026-10-19; in-progress; event atlas-03
  Acceptance: Run one fictional drill; preserve reviewed milestone IDs, source offsets and an explicit backup owner.
