WHERE THE NUMBERS COME FROM.
WHERE THEY GO.

Six input streams, six output products, one instrument in the middle. Every box is a link — tap any station to open it.

INPUTS — WHAT THE PILOT SUPPLIES OUTPUTS — WHAT THE PROGRAM RECEIVES Open Hindsight Daily — the dial The dial — W, 0–10 one number at night · note Repair Bay — one-tag repair logging Repair tags · i5.5.11 label · dose · intent Repair Bay — coupon tests, declared before the run Coupon tests · i5.2.13 declared before the run Open Hindsight Daily — the Mission tab Mission chips · i5.1.2 −1 / 0 / +1 — built it today?

No server-side copy, no account, no analytics beacon, no third-party SDK. The exported backup file is the only way data ever leaves — and the pilot carries it by hand. Every arrow inside this floor executes on-device.
The amber paths are what the rest of the 𝑖SIP product line consumes. Inputs and reports open the Daily itself; the ledger, the lists, and the 𝑖SRM open their pages. Everything inside the dashed floor executes on-device — the backup file is the only egress, and the pilot carries it by hand.
