Validation and drift

Drift is only detectable on a contract that has been read against a sample.

Last validatedAug 14, 2026 · 4 d ago

20,000 records read in the sample.

Validated against a 20,000-record extract. The most recently checked contract on the estate.

The field list

6 fields · 1 key · 1 personal. The validation rule on each row is what admits or rejects a record at the staging boundary.

Field	Source	Target	Type	Flags	Drift	Validation
System id	sys_id	request.ref	string(32)	keyinternal	In contract	Thirty-two character hex. Idempotence key.
Number	number	request.displayRef	string(12)	internal	In contract	Human-facing reference. Not unique across instances, so never used as a key.
Assignment group	assignment_group	request.queue	string(60)	internal	In contract	Must resolve to a queue in the capacity plan.
Priority	priority	request.priority	integer	internal	In contract	One to five. Drives the service-level clock.
Opened at	opened_at	request.openedAt	timestamp	internal	In contract	UTC. A local-time value would silently shift every clock and the contract rejects any payload without a zone.
Caller	caller_id	request.callerHash	string(64)	personalconfidential	In contract	Pseudonymized at the boundary.

What this contract is, and what it is not

A contract, a validation rule, a freshness commitment and a replay path are real mechanisms and they are what this wave builds. more

The last validation read 20,000 records 4 days ago, which is 32% of a single day at the declared volume. A sample proves the shape of what it read and nothing beyond it.
