Summary by CodeRabbit
WalkthroughAllocation and IP block lifecycle operations now enforce source lineage, scoped visibility, transactional rechecks, deterministic advisory locks, and explicit conflict handling. Workflow deletion handles corrupt records and rollback consistently. Migrations add and protect the new lineage fields. ChangesIP block lineage and persistence
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The change adds source-aware ownership and fail-closed behavior, but the current implementation can still expose IP Block results across provider boundaries, turn contention into server errors, hold locks across remote workflows, and leave cleanup incomplete or stalled. These privacy, availability, and correctness risks should be fixed or explicitly accepted before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

181-257: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winShare one case table between the update and delete suites.
Both tables declare identical cases. Only the invoked handler differs. A single table plus an action function keeps the two suites in step when a new lineage failure mode is added.

sitePrefixIDis shared by theConfiguredcase on Line 209 and theTenantSitePrefixcase on Line 210. Both cases expect success, so the test leaves two live rows with the samesite_prefix_id.The model-only schema is built by
ResetModel, which does not create theip_block_live_site_prefix_id_keypartial unique index. That index exists only in the migration. The test therefore passes while encoding a state the migrated schema rejects.♻️ Proposed fix

The index statements at Lines 103-111 do not use CONCURRENTLY, so writes block for the entire build.CREATE INDEX CONCURRENTLYcannot run inside a transaction, so the single-transaction design is a deliberate trade-off and not a defect.For large deployments, consider two operational items:
- Measure the backfill and index build against a production-sized copy so the maintenance window is known before rollout.

720-733: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExtract the lineage-lock constraint names into named constants.
The two constraint names are string literals here at Lines 728-729, in the migration at Lines 146 and 339, and again in
common_test.goat Lines 57 and 65. If the migration renames a constraint, this classifier silently stops matching and clients receive 500 instead of a retryable 409. No test would fail, because the test hardcodes the same literals independently.Named constants make the coupling explicit and give the test a single source of truth.

- Around line 162-167: Update the error handling after GetIPBlockFromIDString in
the VPC prefix handler to return HTTP 404 when the error is cdb.ErrDoesNotExist,
including filtered cross-tenant or disallowed-origin blocks; retain HTTP 400 for
malformed IDs and return HTTP 500 for unexpected database errors, while
preserving the existing API error response structure.

2002-2003: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winDocument the specific 409 trigger conditions for Allocation and IP Block endpoints.
The new
409 ConflictErrorresponse is added to Create/Delete/Update Allocation, Update Allocation Constraint, and Create/Update/Delete IP Block. The PR objective states that "transient lineage contention and persistent repair-required ambiguity return distinct 409 responses." TheConflictErrorcomponent at Line 28862 documents this distinction only through two generic examples (operator-repairandlineage-busy).None of the six endpoint descriptions explain when each cause applies for that specific operation. Compare this to the
get-ipblockoperation description at Line 2536, which explicitly documents the 404 semantics ("An ID hidden by source or ownership policy returns the same 404 response as an ID that does not exist"). Clients cannot distinguish a retryable lineage lock from a state requiring operator repair without inspecting the response body'smessagefield, which is undocumented per-endpoint.Add a short note to each affected operation description clarifying which lineage conditions produce each 409 cause for that specific operation.

The statement list mixes two intents. The column addition uses
ADD COLUMN IF NOT EXISTS, which implies tolerance of partial prior state. The constraints, indexes, and triggers use plainADD CONSTRAINTandCREATE TRIGGER, which fail if the object already exists.The whole up migration runs inside one transaction, so PostgreSQL rolls back every DDL statement on failure and partial state cannot persist.

Both helpers feed raw UUID concatenations into the shared
GetAdvisoryLockIDFromStringspace. Every advisory lock in the process draws from the same 63-bit range.

The comment states that model-only test schemas do not install the migration trigger. That assumption is the only thing that keeps this fixture creatable. If the trigger is later added to the shared test schema helper, this test will fail with an opaque database error instead of a clear signal.
Consider asserting the precondition explicitly, for example by checking that the trigger is absent, so the failure message names the cause.

Follow-up to CodeRabbit review 4935358684: UpdateVpcPrefixesInDB now mirrors the proven Subnet transaction boundary, with WithTx as the single rollback owner and deletion, begin, and commit errors returned for Temporal retry. A deterministic held-lock regression proves error propagation, rollback, and successful retry. The suggested generic transaction retry remains declined because arbitrary closures can contain non-idempotent external work; the name-only Allocation rename trigger claim remains unreachable under the trigger column list. |

75-90: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winMake the deletion order robust for nested lineage.
The helper places every row that has a parent in one bucket and preserves the database order inside that bucket. That guarantees child-before-root for a two-level lineage only.
validateSourceFieldspermits anAllocationrow whose parent is itself anAllocationrow, so a three-level chain is representable. In that case a grandchild can follow its parent in the bucket, and the migration'sip_block_prevent_parent_soft_deletetrigger then rejects the parent delete and stalls Site teardown on retries.Order by lineage depth instead. The change stays local and removes the depth assumption.

Final review-body disposition on
The repeated rename-update Major remains a nonfinding: the reachable tenant/child advisory-lock contention is already mapped to 409 before the write; the later DAO call updates only The shared 409 examples also remain deliberately generic. The component is used by 11 heterogeneous operations whose duplicate/capacity/IPAM messages and data shapes differ; adding endpoint-specific or invented examples would advertise impossible responses elsewhere. The operation descriptions remain the accurate endpoint contract. Local CodeRabbit reported zero findings. Full focused model, handler, comparator, and migration tests passed; every tightened database expectation matched. Compile, vet, changed-lines lint, revive, formatting, and diff checks are clean. |

28986-29010: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAdd examples for the persistent name/prefix conflict variants.
The
ConflictErrorcomponent illustrates only the retryable contention messages (allocation-busy,ip-block-busy) and the operator-repair message. Several operation descriptions reference distinct, persistent (non-retryable) 409 conflicts that are not exemplified here:
- Line 2200: a 409 response for a conflicting Allocation name during update.
- Line 2465: a 409 response for a duplicate provider IP Block name or prefix, or an IPAM prefix conflict, during create.
- Line 2660: a 409 response for another provider IP Block with the requested name during update.
Add example entries for these persistent conflicts. Clients rely on the exact
messagetext to distinguish retryable contention from conflicts that require corrective action before retrying. Without illustrative examples, client implementers must guess the exact wording for these paths.Based on learnings from the referenced documentation: "Declare 409 ConflictError responses for IP Block, Allocation, VPC Prefix, and Subnet mutations, distinguishing retryable allocation/IP Block contention from persistent lineage or operator-repair conflicts."📝 Proposed additional examples

We don't need a Legacy option. Current REST model only allows the following 2 scenarios:
- If
tenant_idis set, then it'sAllocation - If
tenant_idis not set, then it'sSiteFabric
We now have automatic IP Block creation from Site's fabric prefixes in runtime config, so Provider will not need to create these anymore. What Provider was previously doing was adding IP Blocks from Site Fabric config manually.

We should define these as receiver functions of owner object and not in this module that is meant to be generic. For example - this one should be a receiver function GetAdvisoryLockForTenant of IPBlock and accept tenantID as an argument.

This seems incredibly complex for what it is doing. It should very simple.
- Start a transaction
- Add new columns
- Assign
SiteFabricorAllocationbased ontenant_ide.g.
UPDATE ip_block
SET origin = CASE
WHEN tenant_id IS NULL THEN 'SiteFabric'
WHEN tenant_id IS NOT NULL THEN 'Allocation'
END;- Filter allocation_constraint by resource_type=
IPBlock, create a map ofresource_type_idtoderived_resource_id
Construct a SQL dynamically:
UPDATE ip_block
SET parent_ip_block_id = CASE
WHEN id = <derived_resource_id-1> THEN <resource_type_id-1>
WHEN id = <derived_resource_id-2> THEN <resource_type_id-2>
END
WHERE id IN (derived_resource_ids);Also seems this is possible using UPDATE ... FROM (VALUES ...)
- End transaction
We should not need any triggers, dropping/re-adding foreign keys constraints etc.

1227-1238: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winThe rename path still reports lineage contention as HTTP 500.
ipbDAO.Updatewrites the childip_blockrow that theip_block_parent_child_lock_busyserialization guard protects. Three sibling mutations translate that failure into a retryable 409 throughcommon.NewIPBlockContentionAPIError: create at Line 350, child delete at Line 1614, and constraint delete at Line 1632. This rename path does not. A transient contention therefore reaches the client as a non-retryable 500, and the client stops instead of retrying.A previous review raised this concern and it was marked as addressed, but the current code does not contain the mapping.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
The tenant/IP-Block advisory lock is held across a synchronous Site workflow call in both lifecycle paths. Each handler acquires the lock at the start of the cdb.WithTx closure and then blocks on we.Get for the remote workflow. The lock, the transaction, and a pooled connection stay held for the full remote round trip, so concurrent tenant operations on one IP Block exhaust the bounded TryAcquireAdvisoryLock retries and receive 409 or 500.
rest-api/api/pkg/api/handler/vpcprefix.go#L199-L236: narrow the critical section so the lock covers the scoped re-read, the IPAM child allocation, and the record insert only. Move theExecuteWorkflowandwe.Getcalls at Lines 287-311 outside the locked transaction, and add a compensating cleanup for workflow failure.rest-api/api/pkg/api/handler/vpcprefix.go#L1086-L1093: apply the same boundary change. Keep the lock over the status update and the Status Detail insert, and move the synchronous delete workflow at Lines 1130-1166 outside the locked transaction.
If the current boundary is required for atomicity with the Site, record that decision in a comment at each lock site and confirm that the retry budget exceeds the expected workflow latency.

REST currently has to infer IP Block ownership from tenant and Allocation fields. Those fields cannot distinguish provider roots, configured roots, Allocation-derived children, or uncertain historical rows, so they are not a safe basis for SitePrefix projection or provider-facing privacy.
This persists an explicit source, parent IP Block, and Core SitePrefix ID. The migration reconstructs an Allocation child's parent only when one active Allocation Constraint proves the relationship and leaves uncertain rows as Legacy. Database checks protect later source and parent updates during rolling deployments. The REST DAO and handlers now use explicit source-aware filters, require the expected parent and Allocation owner for derived-resource mutations, serialize every tenant consumer on the same child key, and fail closed when historical records need repair or an operation is busy.

Testing
Additional Notes
The IP Block resource schema is unchanged. The OpenAPI contract now documents the privacy-preserving 404 and the operation-specific 409 responses for retryable Allocation or IP Block contention and a persistent parent association that requires operator repair. The generated Go SDK and published reference are included.
Configured roots deliberately allow a nullable Core SitePrefix ID before adoption and a stable ID afterward so #3898 can reconcile an imported root without creating a duplicate projection. Historical duplicate constraints remain available for operator adjudication rather than being discarded or guessed during migration.
