FIELD NOTE / LINKEDIN
A steward is a hypothesis.
The short film, the complete written thought, and the evidence behind it.

A steward is a hypothesis.

A steward is a hypothesis.
Misses, false holds and people time belong together.
Move facts, revoke holds, suppress the steward.
My rule: Complexity needs evidence of net value.

I would compare four complete workflows on the same owner-labeled migration cases: baseline search, long context, source-aware retrieval and a domain steward. Every route gets the same service rule and target-state oracle.
Measure critical-fact recall at dispatch, wrong cutovers, unnecessary holds, reviewer minutes, latency, maintenance burden and recovery cost. Keep expensive exceptions visible rather than letting a routine-case average hide them.
A protected set should include approval-only, open and resolved cohorts, contradictory sources and absent records. Rerun after a policy update and with the supervisor offline. Require service and target readback.
Do that because a second agent creates a new update stream and review queue. If source-aware retrieval plus a deterministic gate passes the contract, use it; add a steward only for a measured gap.

Four-beat scene transcript
1. A steward is a hypothesis.
I would compare four complete workflows on the same owner-labeled migration cases: baseline search, long context, source-aware retrieval and a domain steward. Every route gets the same service rule and target-state oracle.
Visual: It earns its place against simpler retrieval.
2. Score accepted work.
Measure critical-fact recall at dispatch, wrong cutovers, unnecessary holds, reviewer minutes, latency, maintenance burden and recovery cost. Keep expensive exceptions visible rather than letting a routine-case average hide them.
Visual: Misses, false holds and people time belong together.
3. Test perturbations, not demos.
A protected set should include approval-only, open and resolved cohorts, contradictory sources and absent records. Rerun after a policy update and with the supervisor offline. Require service and target readback.
Visual: Move facts, revoke holds, suppress the steward.
4. Choose the smallest passing system.
Do that because a second agent creates a new update stream and review queue. If source-aware retrieval plus a deterministic gate passes the contract, use it; add a steward only for a measured gap.
Visual: Complexity needs evidence of net value.
