Trusted data
Every input behind the 27A-1000 calculation, with its source, owner, trust state and whether it was used.
Trust precedence in force
Configurable by data type and customer policy.
- 1. Physically verified
- 2. Independently corroborated
- 3. Trusted current
- 4. Last known good
- 5. Supplier reported
- 6. Stale
- 7. Assumption
- 8. Unknown
Potentially compromised data sits outside this order. It is blocked from every calculation until an executive authorization is recorded with a documented reason.

Calculation trace
Every line names the source of its value.
- Usable inventory = on hand 0 − quarantined 0 − reserved 170 − unusable 0 = 0 units (on hand from Manual count sheet).
- Verified available supply = usable 0 + confirmed inbound 645 + approved transfer 0 = 645 units.
- Excluded from supply: 480 units claimed by the supplier without an ASN, carrier reference or gate scan.
- Time to impact = 645 ÷ 91.8/hr = 7h.
- Units exposed = planned 2208 − supportable 322 = 1886 units over 48h.
Input fingerprint 0/0/170/0/91.8/645/2208/0/u/h/. Any change to it invalidates approvals already recorded.
