The adapter catalog stops offering NativeJSONMapper once no subscription is saved with it. One check on the endpoint every mapper picker reads, so all five screens follow: subscriptions, scheduled jobs, gateway subscriptions, aggregations, bus studio.

Nothing about the old mapper itself changes. A subscription already on it keeps running and keeps its own editor — it just stops being a choice for new ones, and the mapper leaves the pickers by itself as the migration finishes rather than when someone remembers to delete it.

Two decisions, both about not taking the mapper away from something that needs it:

  • Inactive subscriptions count. One still holds its template and can be switched back on, and withholding the mapper would leave that subscription's own picker showing nothing selected.
  • Drifted casing counts. The lookup that resolves a mapper at run time is already case-insensitive, so a row stored as nativejsonmapper is a live user.

One-way by design: past the last migration there is no picking it again.

Tests: three integration tests (211 → 214). The main one asserts both directions together, because the answer is a fact about the whole database and a one-direction test would pass or fail on whatever else the collection left behind. native-mapper.spec.ts picked the old mapper straight from the dropdown, so it now creates a subscription on it first — the new precondition made explicit.

Known gaps: hand-typing ?mapper=NativeJSONMapper still opens the old editor, and the client caches the catalog, so the dropdown keeps offering the mapper until the next reload after the last migration.

The adapter catalog drops NativeJSONMapper once no subscription is saved
with it, so the mapper leaves the pickers by itself as the migration
finishes. Inactive subscriptions count, and so does drifted casing — a
subscription still on it must not lose it from its own picker.

📝 Summary

Summary

  • Filters NativeJSONMapper from adapter catalogs after the last saved subscription stops using it.
  • Keeps the mapper available for active, inactive, and case-insensitive references until migration completes.
  • Applies the filter to subscription, scheduled job, gateway subscription, aggregation, and Bus Studio pickers.
  • Existing subscriptions retain their mapper and editor. Direct URL access to the old editor remains possible until separately addressed.
  • Adds integration coverage for mapper availability and updates the end-to-end test prerequisite.

Risk: risk:low

Security-sensitive areas: No security-sensitive code or access control changes. The change affects adapter discovery and UI selection.

Test coverage: Adds three integration tests for active usage, final migration, inactive subscriptions, and casing differences. Updates native-mapper.spec.ts.

Operational concerns: The change is one-way after the final migration. Client-side catalogs may remain stale until reload. No database migration is required. Rollback would require restoring catalog exposure for NativeJSONMapper.

Retiring mapper filtering

Retirement filter and search integration
SW.Bitween.Api/Resources/Adapters/RetiringMapper.cs, SW.Bitween.Api/Resources/Adapters/Search.cs, SW.Bitween.Api/Resources/Adapters/SearchVersioned.cs
Adds asynchronous filtering that hides NativeJSONMapper when no subscription references it. Matching is case-insensitive.
Retirement behavior validation

Adds coverage for subscription state, casing, mapper removal, and picker availability.

NativeJSONMapper retirement behavior is covered for the versioned catalog, but the unversioned adapter catalog lacks equivalent regression coverage and could return inconsistent picker options.

Cover the unversioned adapter search.

ListedMappers creates only SearchVersioned. It does not execute the independent filtered path in Search. Add equivalent assertions for Search and validate its dictionary keys, so a regression in consumers of the unversioned catalog is detected.
