assertion_inventory:
  - preparing the writes of a batch outside its transaction
  - what reaches apply
  - prepares with no transaction open
  - writes each item with what was prepared for it
  - writes an item that needs no preparation as it came
  - what is prepared
  - never prepares an item prevalidation refused
  - never prepares an item whose receipt is already there when the batch is delivered again
  - 'never prepares a keyed item the crosswalk says was already delivered, so a re-run copies no file'
  - prepares a keyed item of a newer revision against the record the crosswalk names
  - writes the newer revision’s file over the record the crosswalk names
  - 'prepares nothing in a validate run, which writes nothing'
  - a preparation refused for one item
  - rejects that item as an invalid value of its file
  - applies the rest of the batch
  - writes no crosswalk row for the refused item
  - a storage outage while preparing
  - throws the outage for the queue to deliver the batch again
  - leaves the job running and writes nothing
  - prepares again on the next delivery and applies the item

# Prepared data jobs

## Verification Boundary

The suite checks the production service or shared engine against its database fixture. The structured assertion inventory records the checks present at the pinned revision.

## What This Suite Proves

The existing checks exercise prepared data jobs. The specification bindings identify the narrower outcomes supported by those assertions.

## What It Does Not Prove

Local execution does not establish deployed queue, storage or service behavior. Independent test cases do not establish a complete cross-feature process.

## Real Dependencies and Test Doubles

The shared engine uses real Postgres with a test domain operation and repository. File suites use a fake object store; transport publication uses test ports.

## Must Not Be Doubled

The database effects, security context and production operation under examination remain real. Their outcomes cannot be replaced with canned success responses.
