📝 Walkthrough

Walkthrough

Adds a standalone DynamoDB repair script for stale transaction licenseeId values. The script scans month partitions, resolves provider IDs through a GSI, classifies records, supports dry-run and conditional apply modes, reports aggregate results, and includes integration tests.

Changes

Transaction licensee ID repair

Layer / File(s) Summary
Transaction scanning and provider resolution
backend/compact-connect/bin/repair_transaction_licensee_ids.py
Defines repair records and outcomes. Generates month partitions, scans transactions, resolves provider IDs through compactTransactionIdGSI, and classifies results.
Provider validation and conditional repair
backend/compact-connect/bin/repair_transaction_licensee_ids.py
Checks provider records in batches, processes transactions concurrently, and conditionally updates stale licenseeId values.
Command-line operation and reporting
backend/compact-connect/bin/repair_transaction_licensee_ids.py
Adds command-line options, environment validation, apply confirmation, aggregate logging, and executable entry-point handling.
Mock table wiring and integration tests
backend/compact-connect/lambdas/python/common/tests/__init__.py, backend/compact-connect/lambdas/python/common/tests/function/__init__.py, backend/compact-connect/lambdas/python/common/tests/function/test_repair_transaction_licensee_ids.py
Adds the mocked provider GSI and tests repair outcomes, filtering, idempotency, reporting, privacy, and confirmation behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 79a1a

The temporary repair script can expose transaction identifiers in logs and can mishandle invalid command-line values, potentially omitting data or failing after work starts. These issues should be corrected before merging; the test index-name mismatch is a minor follow-up.

Read the index name from the environment instead of hardcoding it.

tests/__init__.py now sets COMPACT_TRANSACTION_ID_GSI_NAME, and tests/function/__init__.py creates the mocked index from that variable. Line 65 repeats the literal value. If the environment value changes, the mocked table and this call diverge, and the query fails with a ValidationException that looks unrelated to the change.

Less important, but for completeness, why not update the provider ID on declined transactions, too?

We dont have a source of truth for the new providerId, because we are getting that out of privilege which would have had to have been successfully purchased. If the purchase is declined there would never have been a privilege in the first place.

IMO, the test name and comment may be a bit misleading because its testing declined, I think the "unsettled" is supposed to be any not "settled" status.

A privilege that was successfully purchased but then failed settlement would exist but then not be reported, so nothing but fully successfully purchased and settled privileges get reported.

In the case of failed after the fact settles I think we could back populate but I dont believe that has happened yet and our reporting actually treats them all the same. The tests therefor lump them all into one bucket when there are small variations between the states that dont ultimately affect the reporting.

# A full migration deletes the old provider's partition, so this stale id has no provider record
self._put_transaction(transaction_id='tx-full', licensee_id=STALE_PROVIDER_ID)
self._put_privilege(provider_id=CORRECTED_PROVIDER_ID, transaction_id='tx-full')
# A partial migration leaves the old provider in place for its remaining licenses

Hmm, I'm confused by this. What are we testing here? It seems like somehow one provider has had 3 different IDs associated with them?

Sorry this is supposed to be 2 different providers. One undergoes a partial migration and one undergoes a full migration. They both got migrated to CORRECTED_PROVIDER_ID which is not quite representative of the real world / somewhat confusing. but that also isnt really checked / part of what is being tested here so its not super important. Happy to rename the IDs and change them to seperate Ids to more clearly outline what is going on.
