Task 2 report — Make collection ownership unique in the Git registry

Summary

• Implemented unique Qdrant collection ownership enforcement during registry snapshot activation.
• Registry session revision leases now reject migration_required descriptors.
• Legacy migration now requires an explicit target collection and emits schema v3 descriptors.
• Preserved active snapshot rollback behavior on invalid pulled snapshots.

RED evidence

Focused RED command from the brief:

cd backend
npx vitest run test/workspace-registry.test.ts test/workspaces-migrate-legacy.test.ts \
  -t "collection|migration_required"

Observed failures before implementation:

• rejects duplicate schema v3 collection ownership and keeps the previous active snapshot
  • registry.pull() resolved instead of rejecting.
• does not acquire a session revision lease for a migration_required workspace
  • acquireSessionRevision() resolved instead of rejecting.
• migrates a legacy descriptor only with an explicit target collection into schema v3
  • received schema version 1 instead of 3.
• requires an explicit target collection for legacy migration
  • migration did not throw without a collection.

GREEN evidence

Focused GREEN command from the brief:

cd backend
npx vitest run test/workspace-registry.test.ts test/workspaces-migrate-legacy.test.ts \
  -t "collection|migration_required"

Fresh result after implementation:

• 2 files passed
• 4 tests passed
• 0 failures

Additional verification run after final cleanup:

cd backend
npx vitest run test/routes-workspaces.test.ts
npx vitest run
npx tsc --noEmit -p .
git diff --check

Fresh results:

• test/routes-workspaces.test.ts: 7 passed
• full backend Vitest: 39 files passed, 454 tests passed
• backend typecheck: passed
• git diff --check: passed

Changed files

• backend/src/workspaces/registry.ts
• backend/src/workspaces/migrate-legacy.ts
• backend/test/workspace-registry.test.ts
• backend/test/workspaces-migrate-legacy.test.ts
• backend/test/routes-workspaces.test.ts

Why one extra file changed

• backend/test/routes-workspaces.test.ts needed updating because Task 1 made schema v3 the only operational descriptor shape, and the route test still assumed the old pre-Task-3 runtime behavior. Updating that expectation was necessary to keep the required backend suite verification meaningful.

Implementation notes

• Duplicate collection detection is enforced only for operational schema v3 descriptors by tracking collection -> workspaceId during activation.
• Duplicate failures are sanitized back to workspace_invalid / Workspace repository content is invalid.
• acquireSessionRevision() now fails closed for migration_required revisions.
• Legacy migration CLI now requires --collection <qdrant-collection>.
• Legacy migration output is schema v3 with the fixed internal semantic contract:
  • vector_store.engine = qdrant
  • explicit collection
  • embedding provider ollama_internal
  • embedding model qwen3-embedding:0.6b

self-review

• Confirmed invalid pulled snapshots do not replace the previous active snapshot.
• Confirmed duplicate collection enforcement does not affect legacy migration-required descriptors.
• Confirmed create/update publication tests still pass with unique per-workspace collections.
• Confirmed no JSON stdout contract regressions in the migration CLI.
• Kept runtime/data mutation scope descriptor-only; no user workspace repo or Qdrant data changes.

Concerns

• No code concerns remaining for Task 2.
• One deliberate scope exception: a route test was updated to align with the already-established Task 1 / Task 3 fail-closed contract.

Fix round 1

Scope

• Restored meaningful route-level diagnoser coverage without reopening schema-v3 semantic runtime paths.
• Added direct schema-v2 registry coverage for migration_required listing and lease rejection.

Covering test files

• backend/test/routes-workspaces.test.ts
• backend/test/workspace-registry.test.ts

RED command and output

Command:

cd backend
npx vitest run test/routes-workspaces.test.ts test/workspace-registry.test.ts

Observed result on top of 76bc94d after adding the restored/new assertions:

• 2 files passed
• 37 tests passed
• 0 failures

Why no RED appeared:

• The review items exposed missing/weakened coverage, not a production behavior bug.
• /workspaces/:id/test already reaches the diagnoser for resolvable legacy v2 descriptors.
• Schema-v3 /workspaces/:id/test already fails closed before diagnoser entry.
• Schema-v2 descriptors were already listed as migration_required and already rejected by acquireSessionRevision().

GREEN command and output

Command:

cd backend
npx vitest run test/routes-workspaces.test.ts test/workspace-registry.test.ts
npx tsc --noEmit -p .

Fresh results:

• covering tests: 2 files passed, 37 tests passed
• backend typecheck: passed

Changed files

• backend/test/routes-workspaces.test.ts
• backend/test/workspace-registry.test.ts
• .superpowers/sdd/2026-08-08-internal-qdrant-ollama/task-2-report.md

What changed

• Split route coverage so POST /workspaces/validate still checks canonical validation independently.
• Restored route-level diagnoser coverage through a migration-required schema-v2 descriptor with resolvable legacy bindings.
• Added an explicit schema-v3 fail-closed regression for POST /workspaces/:id/test.
• Added a direct schema-v2 registry regression proving list() returns migration_required and acquireSessionRevision() rejects it.

Concerns

• No production concerns. This round only tightened coverage and corrected the weakened test expectation.
