crosses: []
idempotency: >-
  Repeating a cursor targets the same part location and traversal position.
  Values can differ after concurrent edits or deletions because there is no
  export-wide database snapshot.
concurrency: >-
  Each batch has its own read transaction. Parent and collection cut-offs follow
  their declarations, and ongoing changes are not frozen across batches or
  retries.

# Stream Workspace Accounting Export Parts

## What It Does

Accounting exports declared datasets one part at a time. The books dataset combines customer configuration with its owned collections, while Products and batch settings have separate datasets. Each successful call reports a cursor and staged part, and a secret scan rejects recognized processor-secret patterns.

## The Flow

```mermaid
flowchart TD
  h0["Validate export identity, bounds and staging prefix before resolving the participant."]
  h1["Find the declared dataset and validate a configured staging bucket; blank configuration blocks, mismatch refuses and an undefined local hook allows the supplied destination."]
  h0 --> h1
  h2["Complete excluded history with an empty part and warning; return not-applicable only on an initial request lacking dataset data and all financial history."]
  h1 --> h2
  h3["Read the eligible batch, include declared collections, map records into export form and scan serialized content for recognized secret patterns."]
  h2 --> h3
  h4["Write the compressed part to staging and return its descriptor and next cursor or completion."]
  h3 --> h4
```

## When Something Fails

Export does not modify Accounting records. Request and dataset validation precede normal streaming. The deployed bucket check rejects mismatch and blocks an empty configuration, while the undefined hook permits local testing. The writer abandons failed parts, including secret-bearing parts. Retrying reaches the same staging location, but a creation cut-off does not freeze values or guarantee byte-identical parts after configuration changes.

## Open Design Questions

Product needs to understand that this export is a bounded traversal rather than an immutable snapshot. Maintenance registers the configuration participant, while record owners also hold dataset and reader declarations.
