DEMO-20 — Fulfilled, But Late: Post-Transfusion Follow-up Lab
Authored demonstration. Not a live employer result.
01 · Situation
A required post-transfusion follow-up lab specimen is eventually collected, but after the protocol's governing window.
Illustrative transfusion follow-up protocol: transfusion completion automatically triggers a 24-hour specimen-collection obligation assigned to the lab team — no separate order is required.
02 · Evidence
What the record holds.
- E1Transfusion completed at 14:32 on March 1
verified · March 1
- E2Transfusion follow-up protocol, automatic 24-hour collection obligation assigned to the lab team, triggered by transfusion completion
verified · on file prior to March 1
- E3Specimen collected at 16:10 on March 3 — 49 hours 38 minutes after transfusion completion, outside the protocol's 24-hour window

03 · Obligations / Owners
The chain of responsibility.
- 01
Lab team (collect the specimen within 24 hours of transfusion completion, per E2).
04 · Event Type
The classification of the event.
ExecutionClaimed, EvidenceAttached, and VerificationCompleted — E3 claims and evidences the collection, evaluated against the 24-hour requirement in E2 using the exact timestamps in E1 and E3.
05 · Verification Result
What verification established.
SUPPORTED as to both completion and lateness — exact timestamps establish the comparison directly.
06 · Projection
What the evidence implies ahead.
Fulfilled, and late.
07 · Next Action
The corrective obligation.
Track timeliness as a separate metric from completion for follow-up labs; a completed-but-late result should not silently read as fully compliant.
08 · Economic Boundary
Where the evidence stops.
Not established.
09 · Engine Answer
What the Engine can and cannot establish.
The protocol assigns the lab team a 24-hour collection obligation, triggered automatically by transfusion completion at 14:32 on March 1 — no separate order was required. The specimen was collected at 16:10 on March 3, 49 hours 38 minutes later. The Engine can demonstrate, with full timestamps, that the lab team's obligation was fulfilled and that it was fulfilled 25 hours 38 minutes outside the governing window. These are preserved as two separate, both-SUPPORTED findings, not collapsed into a single failed status.
Fulfilled. Also late. Both are true, and neither cancels the other.
10 · What Remains Unknown
Outside the Engine's reach.
Why collection was delayed; whether the delay affected the result's clinical usefulness.
