What checks should I run before accepting an intake sample?

Before accepting a sample, run these checks on the files and on a small number of agent runs, and record the result for each.

- Every foreign key resolves: documents to cases, cases to parties, cases to queues and owners - Status values and transitions in the data match the declared transition table, with no skipped states - Timestamps run forward within each case, and scripted events arrive after the actions that trigger them - Each policy rule is exercised by at least one case, and each exception case maps to a rule - A reference solution passes every task, and a careless always-route baseline fails the tasks with gaps - Resetting twice from the same snapshot and seed gives matching content hashes - Protected fields are listed per task and the grader fails any run that alters them - A sample of names, identifiers and free text is reviewed for resemblance to real parties
