Field notes
Short writing from engagements—source maps, continuity audits, cohort rules, and honest scope.
-

A prettier pack on contradictory sources only accelerates the wrong argument in Sheung Wan boardrooms.
-

A familiar name can hide a remapped status code that rewrote every week-over-week cell.
-
Phantom churn after identity resets
Merged accounts without a bridge table invent attrition that never reached the service desk.
-
What Sys Data Lab does—and does not—sell
Expect systems reporting clarity and owned artefacts, not a managed warehouse machine.
