Serve Catalog v2 from tinyflows-module over an agent-bound CatalogStorage document callback. The module runs workflow list/get, create/update/duplicate, delete, enablement and revision history through FlowCatalogDocuments. Stale updates return a structured conflict with the current workflow. Create results report automatic-trigger disablement and forced approval, while summaries include the latest committed graph revision, run status, trigger kind, node count, update time and skipped-row count.

The graph revision sequence is stored in the catalog definition: new and duplicated workflows start at 1, and only a successful graph update advances it. Failed or stale updates and metadata-only writes preserve the number. Legacy definitions without a sequence bootstrap from visible retained history; history imports remain unseeded until the first graph update persists the sequence, because prior snapshots do not change the current graph. History already pruned before bootstrap cannot be reconstructed.

The bus crate defines serde-only catalog and document callback types, including typed storage preconditions, filters, queries, collection declarations, cursors and result records. Its wire tests cover every type and pin literal request and response JSON. The callback exposes only ensure/get/put/delete/query/delete-where, which cover the current driver’s needs. Module integration tests exercise separate agent scopes, CRUD, stale conflicts, duplicate and enablement behavior, revision history, safety flags and corrupt-row reporting.

Validation:

• cargo fmt --all -- --check
• cargo clippy --all-targets --all-features -- -D warnings
• cargo check -p tinyflows-module --all-features
• cargo test --all-features (pass with Bash 5.3; the existing release-workflow test uses mapfile, unavailable in macOS system Bash 3.2)
