feat(plans): settle a failed-with-submission row so a managed plan can be deleted - #1241
Takeover (claude-ui-fix-1, fleet). This PR was opened by @IAmJSD. I took it over at the coordinator's request, merging main into this branch rather than force-pushing. The added commits:
032fbd14: merge of main.
7d83bc1e: renumbers the migration (now renumbered at merge, see below).
f9fd6c01: a deploy-safety gate (below).
1e902905: the settle conflict response names only the time of the earlier settlement; the earlier settler is logged server-side.
f464387d, 9bd9d309, bcacaa8f: the review fixes. A settled row whose plan was deleted replays; any unsettled failed chain tail blocks settlement; a DB trigger refuses linking a retry to a settled row; the down migration refuses while settlements exist; the CHECK is added NOT VALID and validated by a second migration; the known-issues record is corrected.
The design and tests below are hers unless marked.
Deploy and merge order (read before merging)
Migration number is set at merge (the coordinator's 2026-11-05 policy): the branch currently uses 000157 (add the columns, the NOT VALID CHECK and the retry-refusal trigger) and 000158 (VALIDATE the CHECK). Just before merging, renumber both to the next two free numbers on main (consecutive, settlement first), and re-run the migration and integration tests. The renumber touches:
the 000157_purchase_executions_outcome_settlement* files (up, down, test) and the 000158_validate_purchase_executions_outcome_settlement* files (up, down);
settlementMigrationVersion (internal/config/store_postgres_schema_version.go), which follows the FIRST number only;
the migration test's const version, validateVersion, and the version literals in the new migration tests.
It is still mechanical; note it in the merge comment. Never merge with a number at or below main's highest.
Deploy-safety gate (f9fd6c01). main auto-deploys while prod applies migrations separately, so this code must run against a schema without the settlement migration.
settlementSchemaReady (internal/config/store_postgres_schema_version.go) reads schema_migrations. The schema is ready when the version is above settlementMigrationVersion, or exactly that and not dirty.
Until then, LinkRetryExecutionAtomic and the managed-delete guard use their pre-settlement queries.
POST /api/purchases/{id}/settle returns 503 (ErrExecutionSettleNotReady).
Tests: TestSettlementSchemaReady (unit) and TestSettlementPathsBeforeTheMigration (integration, schema migrated to just below the settlement migration). Removing the gate makes the pre-migration test fail on the missing columns.
The settle endpoint stays disabled until the settlement migration is applied. Don't apply it in prod before a pending follow-up has landed. Merging this PR is safe on its own: with the schema below it, settling is refused and every other path behaves as on main.
Root cause
Deleting an editor-managed plan is refused (409 managed_plan_has_live_executions) while any execution may hold or buy capacity. requireManagedDeleteTx counts a failed row without a no_submission proof as live, because its outcome is unknown and it can still be retried (a retry of a row detached from a deleted plan would buy with no plan). Nothing could ever change that row: failed rows are never pruned, and the retry link isn't consulted. So even after a retry of the row completed, the plan could never be deleted, only disabled.
Fix
As the issue asks, this adds an explicit, audited operator action and leaves delete without a flag. Delete still fails closed on an unknown outcome until a named person has accounted for it.
The settlement migration (number set at merge): purchase_executions.outcome_settled_at, outcome_settled_by (TEXT, so the audit survives user deletion) and outcome_settlement (the complete fixed-format record), with a CHECK that the three are set together. See the merge order above.
Accepts only a failed plan execution with no no_submission proof. Any other status, a no_submission row, an ad-hoc row or a row whose plan is gone gets 409.
Requires Acknowledge and a reason, and stores operator:settled_unknown_outcome: ack=true chain_tail=<id> tail_status=<status> reason="...".
Locks the plan FOR SHARE, then the row FOR UPDATE, then its retry-chain tail FOR UPDATE. That's the same plan-first order as DeletePurchasePlan and the editor command footprint. It re-checks plan_id under the locks.
Refuses while the chain may still buy: a tail outside the terminal allowlist (pending, running and so on), a failed tail that can still be retried (unknown outcome and not itself settled), or a chain past LadderChainMaxDepth.
An identical repeat by the same actor replays (200, replayed: true). A different one gets 409.
What settling does not do: it never changes status and never makes the row count as unbought. holdsCapacity, the ramp ledger (ListPlanCommittedTx), ramp_ledger_holds and the retention trigger are untouched, so a possibly-submitted purchase is never hidden or re-bought. The row stays failed in History after the plan is deleted (plan_id is set to NULL, as for completed rows today). RecoverReapedExecution can still record a late completion over it.
requireManagedDeleteTx skips a settled failed row (blocksManagedDelete). Every other classification is unchanged.
LinkRetryExecutionAtomic also requires outcome_settled_at IS NULL, so a settled row can never be retried. Retry's lost-race 409 now reads "already retried or settled; reload it".
POST /api/purchases/{id}/settle, body {"reason": "...", "acknowledge_unknown_outcome": true}:
Requires execute:purchases (admin:* alone is not enough, matching the separation-of-duties carve-out) and account access to the execution (out of scope gets 404).
Checks the grant's constraints with StrictScope against what the execution would have bought: its recommendations' providers, services, regions and total commitment, plus its accounts. Any dimension the execution leaves unknown requires an unconstrained grant.
The reason must be 10 to 300 characters with no control characters. Unknown fields are rejected.
Logs purchase execution settled by operator with the actor, the credential kind and the stored record.
All of this ran locally on macOS against a real Postgres in Docker (testcontainers). It is unit and integration evidence, not real-cloud evidence. Tests ran with AWS_CONFIG_FILE=/dev/null AWS_SHARED_CREDENTIALS_FILE=/dev/null because this machine's default AWS profile is invalid.

TestSettleFailedExecutionLetsManagedDeleteProceed reproduces the issue scenario: a failed row whose retry completed blocks the delete. After a settle, the delete proceeds, the row is still failed and not no_submission, the audit survives, and ListPlanCommittedTx returns exactly the same ledger before and after.
TestSettleFailedExecutionRefusals covers completed, pending, canceled, failed+no_submission, retry tails pending/running/failed, no plan, not found, and no ack/actor/reason. None of them writes anything.
TestSettleFailedExecutionChainOfUnknownOutcomes checks that the head is refused while its failed tail can still be retried, and that the delete stays blocked until both are settled.
TestSettleFailedExecutionReplayAndRetry covers the replay, the 409 on a different reason, and the retry CAS refusing a settled row.
Races, each queued on a real lock and asserted via pg_stat_activity:
TestSettleWaitsForRetryAndRefusesItsLiveSuccessor: a retry linked first; the settle waits on the row lock, then refuses the pending successor.
TestSettleWaitsForDeleteAndRefusesDetachedRow: a delete holding the plan lock commits first; the settle waits on FOR SHARE, then refuses the detached row.
TestDeleteWaitsForSettleAndSeesIt: a delete queued behind a settle sees the committed settlement.
TestSettleUnblocksManagedPlanDeleteOverHTTP: delete 409, then POST /api/purchases/{id}/settle through HandleRequest (routing and CSRF) returns 200, then delete succeeds.
TestSettleAuthorizationAndValidation: admin without execute gets 403, out of account scope gets 404, execute constrained to another account or provider gets 403, a missing ack, short reason or unknown field gets 400, and a completed row gets 409. A refused settle writes nothing. Execute constrained to the plan's account succeeds.
Unit tests: TestBlocksManagedDelete, TestSettlementRecordReplayMatchesOnlyTheSameReason, TestDecodeExecutionSettle, TestMapExecutionSettleError, plus the migration up/down/CHECK test.
Fail-before / pass-after (mutation probes on this branch, each reverted afterwards):
On main, TestDeleteManagedPlanByExecutionStatus/failed already shows the permanent 409, and no operation existed that could clear it.
Coverage gaps: nothing here touches a real cloud account. The operator's cloud-side check stays a human step, recorded only as the free-text reason and the acknowledgement. The full internal/api integration package was not run, only the subset above.
Out of scope
The delete 409 still doesn't name the blocking execution ids. An operator finds them in History (failed rows of the plan). Adding blocking_execution_ids to the refusal details would be a small follow-up.
History/execution GET responses don't expose the settlement columns yet. The settle response and the server log carry them.
No structured cloud check (account/region/service/checked_at), unlike the ladder resolve, because a plan execution can span several services and regions. The reason field carries it.
Frontend follow-up for the UI owner
On a 409 managed_plan_has_live_executions from plan delete, explain that failed purchases with an unknown outcome must be settled first, and link to the plan's failed executions in History.
In History, for a failed plan execution that isn't no_submission, offer Settle next to Retry. It should open a confirm dialog that asks for a reason (10 to 300 characters) and a required "I checked the cloud account; this may have been bought, and it will never be retried" checkbox. It then sends POST /api/purchases/{id}/settle with {"reason", "acknowledge_unknown_outcome": true}. On 409, show the message (for example, a retry is still pending).
Once settled, hide Retry for that row. That needs the settlement fields on the History payload (see the out-of-scope note above).
Known unrelated CI failure: govulncheck (GO-2026-6809) until #1236 merges.
Current validation (takeover head bcacaa8f)
On macOS, against a real Postgres (testcontainers):
go test -tags integration passes for the whole ./internal/config/ and ./internal/database/postgres/migrations/ packages, and for ./internal/api/ -run Settle.
The unit tests in ./internal/config/ and ./internal/api/ pass.
golangci-lint v2.10.1 on ./internal/config/..., ./internal/api/... and ./internal/database/... reports 0 issues.
Each review fix has a test that fails without it: replay after plan delete, a failed no_submission tail, the retry-link trigger, the guarded down migration, and NOT VALID then validated. Each fix was also neutered once and confirmed to fail its test.
…loud#999)
Migration 000143 adds outcome_settled_at, outcome_settled_by and
outcome_settlement to purchase_executions, with a CHECK that they are set
together. They hold an operator's audited settlement of a failed execution
whose outcome is unknown. Settling never changes status or the ramp
ledger's view of the row.

…lan can be deleted (LeanerCloud#999)
SettleFailedExecution records an operator's acknowledged, reasoned
settlement of a failed plan execution with no no_submission proof. It
locks the plan FOR SHARE, then the row and its retry-chain tail FOR
UPDATE, and refuses while the chain may still buy: a tail outside the
terminal allowlist or a failed tail that can still be retried. Replaying
the same request returns the stored settlement.
The row stays failed and keeps counting as possibly bought in the ramp
ledger. requireManagedDeleteTx skips a settled failed row, and
LinkRetryExecutionAtomic refuses one, since a retry of a row detached
from its deleted plan would buy with no plan.

…ng races (LeanerCloud#999)
Covers the issue scenario (a failed row whose retry completed blocks the
managed delete until settled; the ledger is unchanged), every refusal,
chains of unknown outcomes, replay, the retry CAS, and the three
orderings that matter: a retry that links first, a delete that holds the
plan first, and a delete that queues behind a settle.

…ilures (LeanerCloud#999)
The endpoint needs execute:purchases, account access to the execution
and the grant's constraints against what the execution would have bought
(strict scope), a 10-300 character reason and
acknowledge_unknown_outcome: true. It logs the settlement with the actor
and credential kind. Retry's lost-race 409 now says the row may have
been settled. Marks the known issue resolved.

This change adds an audited settlement operation for failed purchase executions with unknown outcomes. It records settlement metadata without changing execution status, updates retry and managed-plan deletion guards, and exposes the operation through an authenticated HTTP endpoint.

Summary
Settlement schema and readiness internal/database/postgres/migrations/000157_purchase_executions_outcome_settlement.*.sql, internal/config/store_postgres_schema_version.go, internal/config/store_postgres_schema_version_test.go, internal/config/store_postgres_recommendations.go, internal/config/store_postgres_execution_settle_integration_test.go
Migration 157 adds three nullable settlement fields and a constraint requiring them to be all set or all null. Schema-version checks determine settlement readiness and are reused by the Azure pricing migration check. Tests cover migration readiness and behavior before migration 157.
Settlement transaction and retry coordination internal/config/store_postgres_execution_settle.go, internal/config/store_postgres.go, internal/config/store_postgres_execution_settle_test.go, internal/config/store_postgres_execution_settle_integration_test.go
The store settles eligible failed executions after checking and locking the execution and retry-chain tail. Matching repeats replay the stored result; different repeats conflict. Retry linking excludes settled executions when the schema is ready. Tests cover refusals, replay, retry-chain behavior, and transaction races.
Settled failed executions no longer block managed-plan deletion. The guard treats executions as unsettled if the settlement schema is not ready. Tests cover deletion before and after settlement.

The authenticated POST /api/purchases/{id}/settle route validates the request, permission, execution access, and purchase constraints. It maps settlement errors to HTTP responses and returns settlement details. The OpenAPI specification, tests, retry-race response, and issue record are updated.

Explanation
The title "feat(plans): settle a failed-with-submission row so a managed plan can be deleted" matches the main change. The PR adds an audited operator settle endpoint for failed purchase executions with unknown outcomes, and the managed-plan delete guard skips only settled failed rows. The title is specific and identifies the primary behavior. It is slightly long at 81 characters, but it is clear and concise enough for a reviewer scanning history.
Full details: Linked Issues check
Explanation
Linked issue #999 is the only active direct target. Its coding requirements are met at head f9fd6c0.
Reviewed, audited operation to settle a failed-with-submission row. Implemented by SettleFailedExecution (internal/config/store_postgres_execution_settle.go) and POST /api/purchases/{id}/settle (router, handler, OpenAPI). The operation requires an acknowledgement, an actor and a reason. It accepts only failed rows without no_submission on a plan. It writes outcome_settled_at, outcome_settled_by and outcome_settlement (migration 000157). It also writes a log entry.
Delete proceeds after settlement. requireManagedDeleteTx calls blocksManagedDelete, which returns false for a settled failed row. Tests cover this path (TestSettleFailedExecutionLetsManagedDeleteProceed, TestSettleUnblocksManagedPlanDeleteOverHTTP).
Delete stays fail-closed with no flag. Unsettled failed rows and other capacity-holding statuses still block. The PR adds no flag to delete. TestBlocksManagedDelete covers the status matrix.
Tracking. known_issues/35_legacy_guard_followups.md marks the #999 entry resolved.
holdsCapacity (named in the issue) is unchanged. The issue names it as context, and the operation does not need it to change. The settle endpoint returns 503 until migration 000157 is applied. This is a deployment gate, not a missing code path.
Evidence basis: I read the head source for the guard and the settle store. I did not rerun the tests. The test results rely on the PR description and the summary, and the code I read matches them.
Full details: Out of Scope Changes check
Explanation
Each changed area ties to the settle operation or its deploy gate:
Settle store, handler, router, OpenAPI entry and handler error mapping: implement the #999 operation.
Migration 000157, its down migration and its migration test: store the settlement columns and the CHECK.
requireManagedDeleteTx and blocksManagedDelete: let delete proceed for settled rows.
LinkRetryExecutionAtomic and the handler_purchases.go message: stop a settled row from being retried.
store_postgres_schema_version.go and its test, and the schema-ready checks: the deploy-safety gate for the migration.
checkAzurePricingMigration in store_postgres_recommendations.go: now reuses readSchemaVersion. This is a small refactor that shares the new version helper. The change is not part of the #999 behavior. I did not inspect the prior code path, so I rely on the summary for equivalence.
The PR objectives include a stale comment about renumbering to 000146. The current description and head use 000157, so that comment does not apply to this head.
No change at head lacks a connection to #999 or to the settlement gate.

Merged origin/main (at a14dc8f) to resolve the conflict in known_issues/35_legacy_guard_followups.md. There are no review findings on this PR yet, so the merge is the only change.
fix(auth): require every requested AccountIDs/Providers/Services value to be permitted #1163 (all-match AccountIDs/Providers/Services constraints) applies to the settle handler's requirePermissionConstraints call, which passes every account of the execution. A grant constrained to some of those accounts is now refused. That is stricter, and it matches this PR's intent.
Migration stays 000143. Main's highest is 000134.

One blocking finding has been reported privately to the maintainers.
[non-blocking] internal/config/store_postgres_execution_settle.go:209 (replaySettlement) - No test covers the actor half of the replay check.
Removing *t.settledBy != req.Actor || (M4) passes every test.
If it regressed, a second operator sending the same reason would get 200 replayed:true instead of the promised 409.
Nothing is written, so the impact is audit confusion only.
[non-blocking] settle.go:168 (lockSettleChainTail) - No test covers the retryID != nil "chain changed while settling" refusal (M7 survives).
The window is narrow, because only the tail is locked.
Losing this check would let a settle record a stale chain_tail while a newer successor is live.
[non-blocking] settle.go:21/108 vs handler_execution_settle.go:20/151 - The handler allows up to 300 characters, but the store allows up to 1000 bytes.
A 300-character reason in 4-byte runes (1200 bytes) passes the handler and then gets a 400 that says "1 to 1000 bytes".
The two limits should use the same unit.
[non-blocking] settle.go:149 (checkSettleTarget) - Settle works on a failed row of any plan, not only an editor-managed one (DatesManaged).
On a non-managed plan it unblocks nothing, and only removes Retry permanently.
Restrict it, or state in the PR that this is intended.
Attacked:
The settle transition runs in one transaction. The lock order is:
the plan FOR SHARE;
the row FOR UPDATE, with a plan_id re-check;
the tail FOR UPDATE;
a CAS UPDATE WHERE outcome_settled_at IS NULL.
Status, no_submission, settledAt and the tail are all judged under those locks.
Retry:LinkRetryExecutionAtomic is the only writer of the retry link (store_postgres.go:1201, with one caller at handler_purchases.go:2633). Under READ COMMITTED it re-evaluates outcome_settled_at IS NULL after the settle commits, so whichever side commits first wins.
Re-drive only claims approved rows (manager.go:620).
The reaper only CASes running and approved rows. Its follow-up annotation (reaper.go:283) and RecoverReapedExecution both go through SavePurchaseExecutionTx, whose DO UPDATE SET covers neither plan_id nor the settlement columns (store_postgres.go:1096-1120). So a late completion over a settled, detached row still records the money and keeps the audit stamp.
Ladder executions have no plan_id, so settle refuses them (409).
Outcome recording:
Status and no_submission are untouched.
holdsCapacity, ramp_ledger_holds and the retention trigger are unchanged.
DeletePurchasePlan drops suppressions only for pending, notified and paused rows (store_postgres.go:900-910). So a settled failed row keeps its suppressions and its ledger spend.
The test asserts the ledger is identical before and after the settle.
The delete gate:blocksManagedDelete skips only a settled failed row. Unsettled failed rows, including the chain head, keep blocking (ChainOfUnknownOutcomes).
Migration 000143:
Up and down are symmetric: 3 columns plus an all-or-none CHECK.
Independent review (IAmJSD's agent, fresh context, given only the diff, the issue and the PR text): VERDICT: APPROVE a190e552c908a1077ca954e01449534e372d694e
Blocking:
none
Non-blocking:
Merge conflict with main. The PR is CONFLICTING. git merge-tree shows one conflict, in internal/api/handler_purchases.go: main's chore(api): remove dead submit-dedupe code and lock the retry-successor path #1217 moved the body of persistRetrySuccessorTx into writeRetrySuccessorTx. The resolution should carry the "already retried or settled" 409 text into main's new location. The authoritative guard is the outcome_settled_at IS NULL predicate in LinkRetryExecutionAtomic (store_postgres.go), which merges cleanly. The new head needs a fresh review.
Migration 000143 up (000143_purchase_executions_outcome_settlement.up.sql:19): ADD CONSTRAINT ... CHECK validates every row while holding ACCESS EXCLUSIVE on purchase_executions. All rows are NULL, so it passes, but it is a full scan under the strongest lock. ADD CONSTRAINT ... NOT VALID followed by VALIDATE CONSTRAINT would avoid that if the table is large in any deployment. The number (143) matches the reservation for feat(plans): settle a failed-with-submission row so a managed plan can be deleted #1241. Up, down and re-up are covered by the migration test and pass.
Rolling deploy. Until every instance runs the new LinkRetryExecutionAtomic, an old instance could still retry a row that a new instance just settled. The window is small and requires both actions at once. Noting it, not blocking.
Reason length mismatch (internal/api/handler_execution_settle.go:20 vs internal/config/store_postgres_execution_settle.go:21): the handler allows 300 runes, but the store caps the reason at 1000 bytes. A 300-character reason of 4-byte runes (e.g. emoji or CJK extension characters) passes the handler and then gets the store's 400 "reason must be 1 to 1000 bytes". It's harmless, but the two limits should agree.
No 4-eyes on settle. One execute:purchases holder can settle a row, which permanently retires it from retry and lets the managed plan be deleted. This moves no money, but it is a policy choice. I've flagged it for the acting owner.
History doesn't show the settlement yet (out of scope, per the body). The UI will still offer Retry on a settled row, and that click returns the new 409.
(From an earlier review, which I agree with.) checkSettleTarget accepts a failed row of any plan, not only an editor-managed one. On a non-managed plan, settling unblocks nothing and only removes Retry for good. Either restrict it to dates_managed plans or say in the PR that this is intended.
(From an earlier review.) No test covers the actor half of replaySettlement (*t.settledBy != req.Actor) or the "retry chain changed while settling" refusal in lockSettleChainTail. Each is a one-test gap.
An earlier review on this same head (cristim, 2026-10-25) says one blocking finding was reported privately to the maintainers. I could not see it, so this approval does not cover it. That finding needs to be resolved before merge.
Attacked:
Money/guard paths. I read requireManagedDeleteTx/blocksManagedDelete: only an operator-settled failed row stops blocking, and every other classification is unchanged. holdsCapacity, the ramp ledger and the retention paths are untouched, which the integration test asserts (ListPlanCommittedTx unchanged across the settle).
Other ways out of failed. I grepped for paths that move a row out of failed: only the retry CAS and RecoverReapedExecution (failed to completed, which is harmless), so the CAS predicate is enough to stop a settled row from being bought again.
Retry atomicity. The retry inserts the successor and links it in one tx, so a settled row makes the link match 0 rows and the successor is rolled back.
Lock order. plan FOR SHARE, then row FOR UPDATE, then tail FOR UPDATE. This is compatible with the delete (plan lock first) and the retry (row only), and the three race tests queue on real locks.
Authorization.execute:purchases (admin alone is refused), requireExecutionAccess, then StrictScope constraint sets with the execution's accounts. Ad-hoc rows, no_submission rows and rows whose plan is gone are refused.
Fail-before. In my scratch checkout I reverted blocksManagedDelete's settled branch and the CAS predicate, then ran -tags integration -run 'TestSettle|TestDeleteWaitsForSettle' ./internal/config/. Four tests failed: LetsManagedDeleteProceed, ChainOfUnknownOutcomes, ReplayAndRetry and TestDeleteWaitsForSettleAndSeesIt. I restored the PR's code afterwards.
Commands.go build ./...; go vet with and without -tags integration on internal/{api,config,database/...}; go test -race -short -count=1 on the same packages, ok; go test -race -tags integration -count=1 on ./internal/config/ (180s), ./internal/database/postgres/migrations/ (177s) and the full ./internal/api/ (258s), all ok; golangci-lint v2.10.1 with and without the integration tag, 0 issues; gocyclo -over 10 on the changed non-test files, silent.

Settlement inherits current plan membership for plan-level executions.
A failed execution with no CloudAccountID but with a PlanID takes its authorization scope from the plan's current accounts. executionAccounts returns GetPlanAccounts for that plan. The settlement handler then overwrites each constraint set's AccountIDs with those accounts, so the recommendation-level account scope does not limit settlement. The settlement store does not recheck account scope.
This is not limited to legacy rows. Any plan-level row with no CloudAccountID that reaches failed without no_submission takes this path. An all-children-failed execution has this shape. Settlement uses the same scope resolution as retry and cancel. An operator scoped to account B can therefore settle an execution that was attempted against account A. Account membership can change only on non-managed plans, so this path is open for those plans.
Suggested direction
Record the account scope of a plan-level execution when it is created. Check settlement against that recorded scope, not against current plan membership. This change also affects retry, cancel, and approve, so it is broader than this hunk.

Update the plan-level execution scope established at creation so it records the
accounts the execution was attempted against; in settlement, use that recorded
scope instead of current membership returned by executionAccounts. Ensure retry,
cancel, and approve use the same recorded scope, and establish how existing
executions without recorded scope are handled without silently widening
authorization.
replaySettlement returns the stored settlement only when both the actor and the reason match. The replay in TestSettleFailedExecutionReplayAndRetry repeats the request with the same actor and a different reason. No test repeats the original reason under another actor. Removing the actor comparison leaves the suite passing.

Add a settle case that grants the recommendation's provider and service.
The settle authorization cases cover a provider mismatch and an account-only grant. No case grants the provider and service that authorizeExecutionSettle derives from the recommendation. Under StrictScope, listCovers refuses an empty request list against a non-empty grant. A grant that names the recommendation's provider and service therefore fails if those constraints stop being derived. The added case covers provider and service only. It does not cover MaxPurchaseAmount, which needs a recommendation with non-zero costs.

Merge order still applies.#1239 (000154-000156) must merge, and be applied, before this PR's 000157. golang-migrate only moves forward, so applying 157 first would make 154-156 unreachable.
The schema-version gate holds the endpoint at 503 until 000157 is applied
The rule.settlementSchemaReady (store_postgres_schema_version.go) is true only for a version above 157, or exactly 157 and not dirty. No schema_migrations row means not ready.
The unit test pins every case.TestSettlementSchemaReady covers nothing applied, v-1 (= 156), at 157, at 157 dirty, and later-but-dirty.
the managed-delete guard still refuses rather than failing on a missing column;
SettleFailedExecution returns ErrExecutionSettleNotReady, which mapExecutionSettleError turns into 503;
the retry link still works.
It passed in my run.
Every gate check fails closed. The check runs inside the caller's transaction:
SettleFailedExecution checks it first and returns ErrExecutionSettleNotReady, or the read error.
LinkRetryExecutionAtomic and requireManagedDeleteTx return the read error, or use their pre-settlement query.
Safe to deploy before the migration
Every reference to the new columns is behind the gate:
store_postgres_execution_settle.go, after the gate at the top of its transaction;
store_postgres.go:1293;
store_postgres_managed_guard.go:145.
Nothing else names the columns. The handler and openapi references are only response JSON field names.
The Azure pricing readiness check is unchanged in meaning. It moved onto readSchemaVersion, and "no row" still means not ready.
The settle path (managed-only case)
Request order. UUID, then execute:purchases, then a strict body: unknown fields refused, 2 KiB cap, acknowledge_unknown_outcome must be true, reason 10-300 runes with no control characters.
Authorization. Then account access to the execution and the execute constraints against its recommendations and accounts, with StrictScope. Only then the store.
Store-side checks. The store accepts only a failed plan execution without a no_submission proof; anything else is 409. A settled row is replayed, not re-settled. The update is conditional on outcome_settled_at IS NULL.
Effect on delete.blocksManagedDelete treats a settled row as not live, so it no longer blocks the managed plan's delete, and the row keeps its failed status.
The new unit test files don't build on main (undefined: blocksManagedDelete, ExecutionSettleRequest, settlementRecord, settlementHasReason). That's the expected red for new symbols.
Gate at this head
go vet ./internal/... and go vet -tags integration on api, config and purchase are clean.
Unit tests: api, config and purchase ok.
Integration (-tags integration, Postgres testcontainers): internal/config ok (147s), internal/purchase ok (47s), internal/api ok (194s), internal/database/postgres/migrations ok (150s).
Reviewer: claude-as-qa-lead. This is a delta re-review of f9fd6c0..1e90290 (one commit). My approval at f9fd6c0 is superseded by this one.
The delta is only what it says
Two files change.internal/config/store_postgres_execution_settle.go (+7/-2) and its unit test (+20). No migration, handler, openapi or gate change.
replaySettlement's conflict no longer names the earlier settler. It now returns "%w: already settled at <RFC3339>". The earlier settler and the time go to a server-side logging.Infof instead. Both refusal branches go through this one return: a different actor, or the same actor with a different reason.
The replay path is unchanged. Same actor and same reason still return the stored settlement with Replayed: true.
Verified
The new test pins both branches.TestReplaySettlementConflictOmitsTheEarlierSettler covers "another actor" and "another reason". It asserts the error is ErrExecutionSettleConflict, doesn't contain the settler ID, and does contain the time.
The new test fails on the previous head. With f9fd6c0's store_postgres_execution_settle.go and this head's test, it fails with "... already settled by settler-principal-7f3a at 2026-11-04T12:00:00Z" names the earlier settler.
the Settle|Settlement unit tests in internal/config and internal/api pass;
go test -tags integration ./internal/config passes (73s).
My other findings at f9fd6c0 still apply unchanged (the schema gate, deploy safety, the settle path, integration for api/purchase/migrations), since the delta doesn't touch those paths. The merge order still holds: #1239 first.
Cold review: APPROVE at 1e90290 (merge only after #1239)
Reviewer: claude-qa-ui-3, a non-author with no author transcript. I reviewed the full diff origin/main...f9fd6c01, then the delta f9fd6c01..1e902905, and read the PR body as a claim to check.
Delta at 1e90290. One commit, store_postgres_execution_settle.go +7/-2 and its unit test +20. The settle-conflict 409 now names only the time, and the earlier settler is logged server-side. Nothing else changed. No test, frontend code or other caller depends on the old text (grep of already settled and settled by).
Merge order
000157 sits after main's 000153, so it leaves a gap where #1239's 000154-000156 go. golang-migrate only moves forward from the recorded version. If this PR merged and prod migrated to 157 first, #1239's three migrations would never run. #1239 has to merge and be applied first, as the body says. #1239 is still OPEN.
What I attacked
The schema-version gate.settlementSchemaReady (store_postgres_schema_version.go) is true only for version > 157, or 157 and not dirty. It's read inside the caller's transaction, so all three paths decide on the same snapshot:
settle: ErrExecutionSettleNotReady, which mapExecutionSettleError maps to 503;
the retry link: the old query without outcome_settled_at;
the managed-delete guard: the old query, with a constant false in place of the column.
No other non-test Go reads the new columns (grep of outcome_settle across internal/).
The PR's own pre-migration test migrates down to migrationBelow(157), which is 153 on this branch, not 156 as the body says. So I added reviewer scratch tests, not pushed, that pin schema_migrations to 156 (prod's state after #1239):
one at the store level, with the columns absent;
one through HandleRequest, which asserts a 503 and that nothing was written;
version 157 with dirty = true must still refuse.
Both scratch tests pass: TestReview_SettleGateAtVersion156 (store) and TestReview_SettleIs503AtVersion156 (HTTP 503; the row stays unsettled and the delete is still refused). They pass at f9fd6c0 and again at 1e90290. Probes G1-G3 below show the gate's three branches are pinned.
The settle path in the managed case.
Lock order: plan FOR SHARE, then the execution FOR UPDATE, then the chain tail FOR UPDATE. That matches DeletePurchasePlan and the editor command.
A plan_id that changed between the unlocked read and the lock is refused.
Only failed rows without no_submission can be settled.
The chain walk is depth-capped by LadderChainMaxDepth. A tail that isn't terminal, or a failed tail that's still retryable, is refused.
The UPDATE is guarded by outcome_settled_at IS NULL, and the CHECK enforces all-or-nothing.
Settling never changes status or no_submission, so the ramp ledger still counts the row as possibly bought. TestSettleFailedExecutionLetsManagedDeleteProceed asserts the ledger doesn't change.
requireManagedDeleteTx runs only when DatesManaged is set (store_postgres.go:964), and blocksManagedDelete releases only settled failed rows.
LinkRetryExecutionAtomic refuses settled rows inside the successor-insert transaction, so a lost link rolls the successor back.
Deploy safety before the migration. With the schema below 157, every path except settle runs its pre-PR query, and settle returns 503 instead of hitting a missing column. The only changed user-visible text on that path is the retry race 409 ("already retried or settled; reload it").
Fail-before
On main, the settle tests cannot compile (SettleFailedExecution and the endpoint don't exist), so they fail there.
Mutation probes ran in a scratch copy, 10 in all, on the integration suite of ./internal/config/, each reverted at once:
Gate: always ready, ready when 157 is dirty, ready at 156.
Guard and retry: the delete guard ignores settlement; the retry link ignores settlement.
Settle checks: no_submission allowed, non-failed allowed, a retryable tail allowed, a plan change ignored.
Replay: any actor may replay.
At f9fd6c0, 9 were killed. The replay-by-another-actor probe survived. At 1e90290, the new TestReplaySettlementConflictOmitsTheEarlierSettler kills it.
The delta's own fail-before: the new test against f9fd6c0's replaySettlement fails on the old text.
Local verification (macOS, scratch worktree at the SHA)
The 503 mapping has no test.TestMapExecutionSettleError covers 400 and 409 but not ErrExecutionSettleNotReady, which should map to 503. My scratch HTTP test covers it. Worth adding that map entry, plus a version-156 case, to the PR.
The PR text says 000156, but the test migrates to 153. The body says TestSettlementPathsBeforeTheMigration runs with the schema migrated to 000156. It actually migrates to migrationBelow(157), which is 153 until fix(recommendations): key stored recs, rec ID and purchase identity on RDS az_config (#408) #1239 lands. Behaviour is the same, because the gate reads only the version, but the body should say so.
Settle isn't limited to managed plans. It accepts any plan execution. On an unmanaged plan it only stops retries permanently, because delete isn't guarded there. The OpenAPI text says it "can unblock deletion of its managed plan", which is accurate, but a 409 for plans without dates_managed would match the issue's scope. Leaving it open is defensible as an operator choice; please decide explicitly.
Doc nit. The OpenAPI reason says maxLength: 300 and also "at most 1000 UTF-8 bytes". 300 four-byte runes pass the handler and then get a 400 from the store's 1000-byte cap. The outcome is consistent, but the text could say which limit applies first.
…chain tails
An identical repeat settle request now replays the stored result after the
plan was deleted, instead of failing the detached-plan check first. A request
that does not match the stored settlement, or any unsettled detached row, still
conflicts.
A failed retry-chain tail is now treated as possibly retryable whenever it is
not itself settled, including one with a no_submission proof, because retry
still accepts such a tail and a successor of a deleted plan would run as a
direct purchase.

…dation
- 000157 adds a BEFORE UPDATE trigger that rejects linking a retry to a
settled execution, so the "a settled row is never retried" rule holds for
any writer, including a binary from before the settlement code.
- 000157 down now locks purchase_executions and refuses while any settlement
exists, so a reversal cannot silently discard audited settlements. The
check and the drops share one DO block.
- The completeness CHECK is added NOT VALID in 000157 to avoid a table scan
under ACCESS EXCLUSIVE; new migration 000158 validates it (same split as
000121/000122). Both migrations are renumbered together at merge.
settlementSchemaReady keeps gating on 000157 only. The columns, the trigger
and the CHECK (enforced on new writes even when NOT VALID) all exist after
000157, and 000158 only validates existing rows, which the code never relies
on, so requiring it would disable settling for no safety gain.

Reviewer: claude-as-qa-lead. This is a fresh review after the CodeRabbit fix round (1e90290..bcacaa8: three commits). Migration numbers are assigned at merge, so I don't treat them as a blocker.
[3] The trigger refuses linking a retry to a settled row, for any writer
purchase_executions_refuse_retry_of_settled is BEFORE UPDATE OF retry_execution_id. It raises check_violation when OLD.retry_execution_id IS NULL AND NEW.retry_execution_id IS NOT NULL on a row that is settled before or by the statement (OLD/NEW.outcome_settled_at).
What I attacked:
An old binary's direct link. A pre-settlement LinkRetryExecutionAtomic sets retry_execution_id with no settled check in its WHERE. The trigger fires on it. The PR's TestMigration_OutcomeSettlementRefusesRetryLink does exactly this raw UPDATE … SET retry_execution_id.
Probe: I deleted the trigger and its function from the up migration on a scratch copy and reverted afterwards. That test then fails, so the test really depends on the trigger.
The upsert can't bypass it. The execution upsert omits retry_execution_id from its DO UPDATE SET (store_postgres.go:1224), so it never links a settled row. Retry rows are linked only through UPDATE, which the trigger covers.
Concurrent settle and link (I reasoned this one through; I didn't run it). Both are single-row UPDATEs on the same row, so Postgres serializes them on the row lock.
If settle commits first, a new binary's link re-checks its WHERE (AND outcome_settled_at IS NULL) against the new row version under READ COMMITTED and updates 0 rows, while an old binary's link hits the trigger.
If link commits first, settle's SELECT … FOR UPDATE in lockSettleTarget sees the committed retry_execution_id and walks the chain, which lockSettleChainTail checks.
Settle's own UPDATE doesn't SET retry_execution_id, so the trigger never blocks a legitimate settle.
A single statement that links and settles at once is also refused, via NEW.outcome_settled_at.
[4] The down migration refuses while settlements exist
One DO block. It runs LOCK TABLE purchase_executions IN ACCESS EXCLUSIVE MODE, then IF EXISTS (… outcome_settled_at IS NOT NULL) THEN RAISE, then drops the trigger, the function, the constraint and the columns.
Nothing can slip in. The lock is held from the check to the end of the statement's transaction, so no settlement can land between the check and the drop.
The drop order is right. The trigger and function go before the columns they reference.
Tested.TestMigration_OutcomeSettlementDownRefusesWithSettlements covers it.
[5] The CHECK is added NOT VALID, then validated by the follow-up migration
157 adds the all-or-nothing CHECK NOT VALID. It still applies to every new write and skips the full-table scan under the lock.
158 runs VALIDATE CONSTRAINT, which scans without blocking writes.
158's down drops the constraint and re-adds it NOT VALID, matching the state 157 leaves (the same pattern as 000121/000122).
Tested. The migration test asserts validated() is false after 157.
The Go changes
A detached settlement still replays.readDetachedSettleTarget serves a plan-less row only if it is already settled, so an identical repeat request still replays after the plan is deleted. Anything else is the original 409.
The chain check is stricter.lockSettleChainTail now refuses any failed tail that isn't settled itself, whatever its no_submission value, because retry accepts that tail too.
The doc fix names the migration without a stale number.
My first run of this gate overlapped the machine's Go-cache clear and failed with "package … is not in std". I re-ran it on a clean cache; the results above are from that run.
Reviewer: claude-qa-ui-3, a non-author with no author transcript. Scope: the fix round 1e902905..bcacaa8f (3 commits, linear), plus how it interacts with the rest of the PR.
Blocking
A chain ending in a no_submission failed retry can never be settled, so its managed plan can never be deleted.f464387 made any unsettled failed tail refuse the chain (lockSettleChainTail: retryable := tail.status == StatusFailed && !settled). The reason is sound: a no_submission failed tail doesn't block the managed delete, and retryPurchase has no check for detached rows, so after a settle plus a delete the tail could be retried and buy with no plan. But checkSettleTarget still refuses to settle a no_submission row ("proven never submitted and needs no settlement"). So for head (failed, unknown outcome) → tail (failed, no_submission):
settling the head gives 409, "retry … is failed and may still buy or be retried; let it finish or settle it first";
settling the tail gives 409, "execution is proven never submitted and needs no settlement";
DeletePurchasePlan gives managed plan still has active or unsettled purchases.
The 409 advises an action the endpoint refuses. The only way out is to retry the tail, which may buy, and that defeats the point of the settle. This chain shape is ordinary: a retry of an unknown-outcome row that fails before submission. I reproduced it with a reviewer-only test (TestReview_NoSubmissionTailDeadEnd, real Postgres, not pushed); its log lines are the three errors above. The PR's TestSettleRefusesChainWhoseTailIsFailedNoSubmission pins the refusal but not the way out.
Smallest fix I can see: allow settling a no_submission failed row; settling it only stops retries. Alternatively, accept a no_submission tail in the chain walk once it's settled. Either way, add a test where the head, the tail and the delete all succeed in order.
What I attacked and what held
[3] The trigger purchase_executions_refuse_retry_of_settled. The full-row upsert never writes retry_execution_id (SavePurchaseExecutionTx leaves it out of DO UPDATE SET), so every writer, old or new, links through the single link UPDATE. I ran main's link SQL verbatim, as an old binary would. Reviewer-only tests, not pushed:
TestReview_OldBinaryLinkOnSettledRowRollsBack: refused, and the successor insert from the same transaction rolls back (no orphan row).
TestReview_OldBinaryLinkRacingSettle: with an uncommitted settle holding the row lock, the old link waits; after the commit it re-evaluates against the settled row and is refused, with the successor again rolled back.
Probe: dropping CREATE TRIGGER fails both of these and the PR's TestMigration_OutcomeSettlementRefusesRetryLink.
The trigger only fires on NULL → non-NULL links. The settle UPDATE doesn't touch retry_execution_id, so settling an already-linked chain isn't blocked.
[4] The down guard. The LOCK TABLE … ACCESS EXCLUSIVE, the EXISTS check and the drops all sit in one DO block, so no settlement can land between the check and the drop. Probe: replacing the EXISTS check with false fails TestMigration_OutcomeSettlementDownRefusesWithSettlements. A refused down leaves the version dirty at 157. By reading, settlementSchemaReady then reports not ready: settle answers 503 and the delete guard treats settled rows as live, so it fails closed, and the trigger keeps refusing links. A rollback runbook should say what an operator does with existing settlements (non-blocking).
[5] NOT VALID, then VALIDATE (000158). The new columns are nullable with no default, and the CHECK is added NOT VALID. 000158 validates it, and its down re-adds it NOT VALID. The migration test asserts convalidated false then true. settlementSchemaReady keys on 157, where the columns exist, and 158 dirty still counts as ready. That's correct. One merge-time note: the Go constant settlementMigrationVersion must be renumbered together with both files.
Replay before the detached refusal.readDetachedSettleTarget returns only a row that's already settled, so an identical repeat replays and a different one conflicts after the plan is deleted (TestSettleReplayAfterPlanDelete). It skips the lock because a written settlement never changes. That holds: the settle UPDATE requires outcome_settled_at IS NULL.
Doc fix.known_issues/resolved/35 no longer names a stale migration number. It's fine.

A failed execution carrying a no_submission proof is still accepted by retry,
so a retry chain whose tail is such a row could never be settled: the head was
refused while the tail was unsettled, and the tail was refused as needing no
settlement. Settling it is safe because nothing was submitted, and it only
stops further retries. The other refusals are unchanged: non-failed status,
rows without a plan, and a chain that may still buy.

New head bd4013463ef610ec68726128aef73f93c4e6c5b9, addressing claude-qa-ui-3's REQUEST_CHANGES at bcacaa8f.
Finding: a chain head (failed, unknown outcome) → tail (failed, no_submission) could never be settled. The head was refused while the tail was unsettled, and the tail was refused as never submitted. So the managed plan couldn't be deleted without a retry, and the 409 advised an impossible action.
Fix:bd401346 allows settling a failed no_submission row. Nothing was submitted, so settling it only stops retries: the LinkRetryExecutionAtomic WHERE clause and the purchase_executions_refuse_retry_of_settled trigger both refuse a settled row. Every other refusal is unchanged: non-failed status, no plan, and a chain that may still buy.
Tests (both failed first with ErrExecutionSettleConflict):
TestSettleFailedNoSubmissionChain is the reviewer's scenario end to end:
settling the head gives 409 while the tail is unsettled;
settling the tail succeeds, then settling the head succeeds;
the ramp ledger is identical before and after;
DeletePurchasePlan succeeds;
linking a retry on the settled tail is refused.
TestSettleFailedNoSubmissionRow settles a lone row and keeps NoSubmission.
The refusals table no longer lists failed + no_submission.
Deletion probe: re-adding the refusal fails both new tests.
Docs:checkSettleTarget's error and doc, the SettleFailedExecution doc, and the OpenAPI settle description are updated.
Verification:
go test ./internal/config/ ./internal/api/ passes;
go test -tags integration ./internal/config/ passes (whole package);
Reviewer: claude-qa-ui-3 (non-author). Scope: bcacaa8f..bd401346, one commit, linear. It fixes the blocker from my REQUEST_CHANGES at bcacaa8.
The blocker is closed.checkSettleTarget no longer refuses a failed no_submission row. The chain head (unknown outcome) → tail (failed, no_submission) now has a way out, and TestSettleFailedNoSubmissionChain runs it end to end:
The head's settle is still refused while the tail is unsettled.
The tail settles.
The head settles.
DeletePurchasePlan succeeds.
A retry link on the detached tail is refused (linked == false), so the hazard behind f464387 stays closed.
Settling a no_submission row can't mark anything bought.
The settle UPDATE writes only outcome_settled_at, outcome_settled_by and outcome_settlement. It never touches status or no_submission.
TestSettleFailedNoSubmissionRow asserts NoSubmission stays true, and the chain test asserts the ramp ledger (f.committed) is unchanged.
The only non-settle readers of the settlement columns are LinkRetryExecutionAtomic (store_postgres.go:1293, refuse the retry) and the managed-delete guard (store_postgres_managed_guard.go:145). blocksManagedDelete tests !holdsCapacity before it reads the settlement, so a never-submitted row was already non-blocking and still is.
Fail-before. In a scratch copy I restored the no_submission refusal in checkSettleTarget. That fails both TestSettleFailedNoSubmissionChain and TestSettleFailedNoSubmissionRow. The probe was reverted and the tree is clean.

The api change is OpenAPI text only, so I didn't re-run its integration suite; it was green at bcacaa8.

Reviewer: claude-as-qa-lead, a non-author. Scope: bcacaa8f..bd401346 (1 commit), checked against claude-qa-ui-3's REQUEST_CHANGES at bcacaa8f.
The blocker is closed
The chain was head (failed, unknown outcome) → tail (failed, no_submission). checkSettleTarget (store_postgres_execution_settle.go:175-181) now refuses only a non-failed status, so the tail can be settled. After that, lockSettleChainTail sees a failed but settled tail: retryable is false (:211), so the head can be settled. In blocksManagedDelete (store_postgres_managed_guard.go), neither row blocks the delete anymore: the head is failed and settled, and the tail doesn't hold capacity. TestSettleFailedNoSubmissionChain runs exactly this order:
settling the head gives 409;
settling the tail succeeds;
settling the head succeeds;
the ledger is unchanged;
DeletePurchasePlan succeeds;
linking a retry on the settled tail returns linked=false.
Settling a no_submission row can't mark anything as bought
The settle write (:101-104) sets only outcome_settled_at/by/settlement. It never writes status or no_submission, and the WHERE clause also requires outcome_settled_at IS NULL.
Every reader that decides "bought / holds capacity" keys on status + no_submission, never on settlement:
ramp_ledger_holds(status, no_submission) (000124:12-15), which drives the ledger and the retention trigger;
ladder_reconcile (store_postgres_ladder_reconcile.go:106).
Settlement is read in only three places: the delete guard, the retry-link WHERE (store_postgres.go:1293) and the chain walk (:202). All three only stop retries and deletes.
The upsert keeps no_submission sticky while the row is failed (store_postgres.go:1203-1204, old OR new).
The test asserts the committed ledger is identical before and after settling, and that NoSubmission stays true on the settled row.
What I ran (macOS, scratch worktree at the exact SHA, go1.26.10 from go.mod)
go build ./... and go vet -tags integration (config, api): pass.
Unit tests for config and api: pass.
go test -tags integration -count=1, real Postgres via testcontainers:
./internal/config/: pass, 98s;
./internal/api/: pass, 305s;
./internal/database/... (migrations): pass, 175s.
Deletion probe: I re-added the no_submission refusal in checkSettleTarget. TestSettleFailedNoSubmissionChain (:187) and TestSettleFailedNoSubmissionRow (:209) both fail with the conflict error, then pass again once the probe is reverted.
golangci-lint v2.11.4 (CI pins v2.10.1) reports one prealloc hit at store_postgres_history_page_integration_test.go:141. That file isn't in this PR, and the line is identical on main, so it's pre-existing and out of scope here.
Non-blocking (docs and audit text)
The SettleFailedExecution doc (:58-62) still says the ledger "keep[s] treating it as possibly bought". For a no_submission row the ledger treats it as not bought, both before and after settling (which is correct). Suggest: "never changes status or no_submission, so the ledger counts it exactly as before".
settlementRecord writes operator:settled_unknown_outcome for a no_submission row too, although that row's outcome is known (never submitted). It's a fixed audit string, so changing it alters replay comparison; if you change it, do it only for new settlements, or leave it with a doc note.
…ettlements
SettleFailedExecution now says it counts the row in the ledger exactly as
before, which is possibly bought unless the row was never submitted. The
settlementRecord doc notes that its fixed audit tag also covers a
never-submitted row and stays fixed so replays compare equal.

New head 9f79502f12316cf5a329a95932faf0b4f7357939: a merge-only delta on top of the head approved by qa-ui-3 and as-qa-lead (bd401346). Three commits:
2861f4d3 (doc text only), as-qa-lead's two non-blocking nits:
The SettleFailedExecution doc now says it counts the row in the ledger exactly as before: possibly bought, unless it was never submitted.
The settlementRecord doc notes that the fixed settled_unknown_outcome tag also covers a never-submitted row, and stays fixed so replays compare equal. The string itself is unchanged.
The migration tests' const version, validateVersion = 155, 156 and their version literals are updated.
The SQL comments and the known-issues record are updated. No SQL or logic changed.
9f79502f: a merge of origin/main with no conflicts, so the branch contains 000154 and the migrations run 154, 155, 156 in order.
Verification, on this merged tree (macOS, real Postgres):
TestSettlementPathsBeforeTheMigration and TestSettlementSchemaReady pass.
go test -tags integration passes for the whole of ./internal/database/postgres/migrations/ (159s), ./internal/config/ (71s) and ./internal/api/ (112s).
The config and api unit tests pass.
golangci-lint v2.10.1 on config, api and database reports 0 issues.
Merge-only delta review (non-author) against my APPROVE at bd40134. Read-only; I relied on the merged-tree runs the author posted and re-ran nothing.
2861f4d is doc only: comments in store_postgres_execution_settle.go (+5/-4).
f0b4967 renumbers 157/158 to 155/156, and only that.
With rename detection, the SQL diffs are number references only (RAISE EXCEPTION 'cannot reverse 000155 …' plus comments). settlementMigrationVersion is now 155 (store_postgres_schema_version.go), and the migration test constants are 155/156.
No 157/158 reference remains in any file the PR touches.
main's migrations stop at 000154, so 155/156 don't clash.
9f79502 merges main (b3e1b54). git show --remerge-diff is empty, so there are no hand edits in the merge. I compared the PR's own hunks in handler_purchases.go, openapi.yaml and store_postgres.go before and after it (old base ecb118e, new base b3e1b54): they are identical.
The delta holds. CI was still running when I checked; merge pinned at this SHA once it's green.
Merge-only delta against my APPROVE at bd401346. Three commits:
2861f4d3 (docs only): my two nits are addressed.
The SettleFailedExecution doc now says it never changes the status or no_submission, so the ledger counts the row exactly as before.
The fixed settled_unknown_outcome tag is documented as also covering never-submitted rows.
f0b49675 (renumber only):
000157/000158 become 000155/000156, directly after main's 000154, with no collisions or gaps.
settlementMigrationVersion = 155 (store_postgres_schema_version.go). Nothing settlement-related still names 157 or 158.
The SQL changes are only comments and the down-guard error text, and the migration test uses 155/156.
9f79502f (merge of main b3e1b545): conflict-free. In this delta the settle, delete-guard (requireManagedDeleteTx) and retry-link (LinkRetryExecutionAtomic) code is unchanged except for the doc and the constant. Main's new writers don't touch settled rows: GetDoomedNextRoots only reads pending/notified roots, and StampFirstDispatchTx only updates running rows.
Evidence: I did not re-run suites locally for this merge-only delta (per the coordinator's lock guidance, given machine load). I'm relying on:
CI at this exact head (run 42059782169): all 39 checks pass and 2 are skipped, including Integration Tests (api), (config) and (migrations, rest), Lint Code, Database migration down gate, and E2E;
claude-ui-fix-1's merged-tree runs posted on this PR;
my full local integration run at bd401346 (config, api, migrations, plus the deletion probe), which covered all the logic in this delta.
Merged at 9f79502f (approvals from qa-ui-3 and as-qa-lead at that head, CI green, 0 unresolved threads). The delta since the approved bd401346 was: two doc-only nits, the number-only migration renumber to 000155 (settlement) and 000156 (VALIDATE), per the merge-time numbering policy, and a conflict-free merge of main. The merged tree passed the settlement gate test and the full migrations, config and api integration suites. Deploy note: settle stays disabled (503) until 000155 is applied, and 000155 must not be applied in prod before the pending follow-up lands. The next migration on main must use 000157 or higher.

…HECKs, write only canceled_by (#1253)
* fix(db): contract the canceled rename: normalize, narrow the status CHECKs, stop using cancelled_by
Migration 000144 is the contract half of 000089. Under a table lock it
normalizes every legacy 'cancelled' status in purchase_executions and
ri_exchange_history, drains legacy-only actors into canceled_by, and
narrows both status CHECKs to the 000089 lists minus 'cancelled'.
The code stops reading and writing purchase_executions.cancelled_by:
reads project canceled_by, the cancel transition and SetCancelledBy
write only canceled_by, and SavePurchaseExecution writes canceled_by,
keeping an actor already on the row (the value reads saw before). The
LegacyStatusCanceled constant and every dual-spelling branch are gone.
The cancelled_by column is kept. The previous build still reads
COALESCE(canceled_by, cancelled_by) and writes cancelled_by, and it
keeps serving during a rolling deploy and after a code-only rollback,
so dropping the column in the same release would break every execution
read on it. A trigger mirrors any legacy-only actor write into
canceled_by until a follow-up migration drops the trigger and column.

* fix(config): drop the legacy canceled spelling from the history summary test
The test came in from main (#1200) and seeds executions with

status, so the seed would fail the narrowed CHECK. Seed and query only
the canonical spelling.

Only normalize 'cancelled' to 'canceled' on purchase_executions and
ri_exchange_history and narrow both status CHECKs. The mirror trigger,
the cancelled_by drain and the down backfill are cut: this release
keeps reading COALESCE(canceled_by, cancelled_by), so nothing reads
canceled_by alone yet. The row-level updated_at triggers (000128 and
000009) are disabled around the normalization so the plan-health and
retention clock is not restamped. The down only re-widens the CHECKs.
The old test is removed; the new 000158 test follows.

* test(db): cover the 000158 canceled contract migration
Seeds legacy 'cancelled' rows in both tables with a 90-day-old
updated_at, then asserts the normalization, that updated_at is
unchanged on each table (each assertion fails without its trigger
disable), that both triggers are enabled again, the narrowed CHECKs
(23514 on the legacy spelling), and that the down restores the widened
CHECK text exactly.
Also runs the write statements of the build live today (the
SavePurchaseExecutionTx upsert, SetCancelledBy, the
transitionExecutionStatus dual write and CancelAllPendingExchanges)
against the narrowed schema: no 23514, and the actor reads back via
COALESCE(canceled_by, cancelled_by). Written relative to the version
below 158, so it follows the tree as 154-157 land.

The PR removed every tolerant read of the legacy spelling, which is only
safe once 000158 has run and no older build can be rolled back to. Keep
them until the follow-up: LegacyStatusCanceled and the lists and
switches that use it, COALESCE(canceled_by, cancelled_by) in every
execution projection, and status IN ('cancelled', 'canceled') in the
cleanup SQL. Their tests (the legacy-spelling fixtures) are restored.
The PR's write changes stay: SavePurchaseExecution writes
canceled_by = COALESCE(purchase_executions.canceled_by, $17) and no
longer writes cancelled_by, and the cancel transition and
SetCancelledBy write canceled_by only.

Two tests. The projections test asserts all ten purchase_executions

UPDATE that names the legacy column in its write part (RETURNING reads
are exempt) and pins SavePurchaseExecution's
COALESCE(purchase_executions.canceled_by, $17), so a stale-copy save
cannot erase an existing actor.

CountLiveExecutionsForAccount, holdsCapacity, the ramp-step occupied
check, SavePurchaseExecution on a legacy-actor row (the actor is
carried into canceled_by and a stale save cannot erase it),
CleanupOldExecutions, and the handler's cancel-race recovery
(cancelOrRecoverExecution). The build and the migration roll out in
either order, so both orders must read correctly.
Against the original #1253 strict reads the config test fails on the
actor scan, the live count, holdsCapacity, the save and the cleanup,
and the api test fails with a 409.

resolve, ramp baseline, ramp step, ladder reconcile, submit dedupe,
the db retention test, the retention writers case), and have the

spelling. The unit tests keep their legacy fixtures, and the legacy
rows are covered at the pre-000158 schema by the new integration tests.
Also reword comments and mark the SQL constants that name the legacy
column so the misspell linter passes, and drop a stray blank line.

…n RDS az_config (#408) (#1239)
* feat(db): add generated az_config column and 12-column recommendations index (#408)
Migration 000140 adds a generated az_config column, read verbatim from
payload->'details'->>'az_config' (RDS single-az/multi-az, Azure SQL zone
redundancy, '' otherwise), and two unique indexes that include it: the
11-column natural key plus az_config (the new upsert arbiter) and the
000120 source-account key plus az_config.
The existing 11-column and 000120 source indexes are kept, so the current
upsert keeps working and this can be applied before the store switch.

* fix(purchase): carry RDS az_config in rec ID, identity key and idempotency key (#408)
Single-AZ and Multi-AZ RDS recommendations of the same class, engine,
term and payment shared one rec ID and one identity key. Read az_config
verbatim from Details (RecommendationRecord.DetailsAZConfig, pinned to
the 000140 generated column by shared vectors) and add it to
RecIdentityKey, the rec ID (appended only when set, so every other rec
keeps its ID), the purchase idempotency key and describeRec.

* fix(config): upsert recommendations on the 12-column index with az_config (#408)
Requires migration 000140.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* fix(db): drop the recommendations indexes without az_config (#408)
Migration 000141 drops the 11-column natural key and the 000120 source
index, both superseded by the 000140 indexes that add az_config. While
either exists, a collection batch carrying a Single-AZ and a Multi-AZ
RDS recommendation of the same class fails as a whole. The rollback
collapses az_config-only duplicates to the newest row and recreates both.
Apply only after the 12-column upsert is live everywhere.

* fix(deps): bump golang.org/x/net to v0.62.0 (GO-2026-6860, GO-2026-6866)
govulncheck in the Docker image build now fails on these two advisories,
both fixed in x/net v0.62.0.

* fix(recommendations): scope az_config identity to AWS RDS (#408)
Azure SQL's az_config is a subscription-wide dominant value that is empty
when the server lookup is incomplete, so keying the rec ID, identity key and
purchase fingerprint on it flipped Azure SQL IDs between collections for no
benefit. Add IdentityAZConfig, which returns the Details az_config for AWS
RDS and "" for every other rec, and use it in those three places.

* feat(db): add az_config to purchase_suppressions variant (#408)
Add a nullable az_config column and widen the per-execution UNIQUE key so
a Single-AZ and a Multi-AZ RDS suppression of one execution can coexist.
Backfill rule: NULL az_config means unknown or not applicable and is a
wildcard, so every existing row keeps suppressing both offerings, failing
safe against a double purchase. Down merges rows that differ only by
az_config (summed count, latest expiry) before restoring the 000134 key.
Apply as its own deploy step, before the code that writes the column.

* fix(suppressions): key purchase suppressions on RDS az_config (#408)
Migration 000155 lets Single-AZ and Multi-AZ RDS recs of one class
coexist, but the suppression variant lacked az_config, so buying 2x
Single-AZ wrote a suppression that also matched, and hid, the Multi-AZ
rec (an under-buy). SuppressionVariant now carries AZConfig, set for AWS
RDS recs only, and is stored in the new purchase_suppressions.az_config
column.
An empty AZConfig is a wildcard on either side: suppressions written
before migration 000156 and RDS recs without an az_config keep matching
both offerings.
Regression: TestApplySuppressions_RDSAZConfigScopesToPurchasedOffering
failed before (Multi-AZ count 3, want 5) and passes now.

* fix(recommendations): scope generated az_config to AWS RDS
The az_config column was derived for every provider while the rec ID,
identity key and fingerprint only carry it for AWS RDS. A cron collect and
a refresh overlapping on an Azure SQL rec could commit it with az_config
'none' and '', the 12-column upsert key inserted a second row and the
eviction spared it, so the rec was listed twice and could be bought twice.
The column is now '' outside provider aws with service rds or relational-db,
mirroring IdentityAZConfig. Edited in 000154 in place: it is unmerged and
000155/000156 do not reference the expression.

* fix(migrations): order both az_config expand steps before the contract
The suppression az_config migration sorted after the contract migration that
drops the 11-column recommendations key, but the contract can only run after
the release. New code on a database at the last pre-contract version failed
on purchase suppression writes and listing.
Renumber so both expands run first: 000154 recommendations az_config, 000155
purchase_suppressions az_config, 000156 contract. Update the cross-references
in migration comments and store comments, and add an integration test that
runs the new code against a database stopped just below the contract and again
after it.

* feat(config): gate az_config code on the expand migrations
New code that writes az_config failed mid-transaction on a database without
migrations 000154 and 000155. Generalise checkAzurePricingMigration into
checkSchemaVersion and add CheckAZConfigMigration, which returns the typed
ErrAZConfigMigrationNotReady naming the missing migrations.
The purchase path refuses with a 503 before it opens its transaction.
Recommendation writes and suppression listing return the same error, wrapped
with what was skipped, instead of a SQL failure.

* fix(config): gate suppression writes on the az_config expand
CreateSuppressionTx inserts az_config, so every caller (the plan step claim,
attach recommendations, CreateSuppression) failed with a raw SQL error below
migration 000155. Check the schema version at the top of CreateSuppressionTx
and return the typed ErrAZConfigMigrationNotReady, so the transaction rolls
back cleanly for all callers. The handler keeps its pre-transaction 503.

* test(purchase): migrate the Azure pricing fixture past the az_config expand
The fixture stopped at 000154, but the recommendations upsert is now gated
until the 000155 expand, so the re-collection step was refused. Migrate to
000155 and say why in the comment.

* fix(config): run the suppression-write schema check on the caller's transaction
CreateSuppressionTx queried the pool for the az_config schema version while
the caller's transaction was open, taking a second pool connection per
suppression row. Under the plan-step claim's advisory and row locks and a
pool of 3 that can exhaust the pool. Take the check through a rowQuerier
satisfied by both the pool and pgx.Tx, and run it on the tx.

* fix(db): renumber the az_config migrations to 000155-000157 after #1762
Main now has 000154_purchase_executions_first_dispatch_at. Move the
recommendations az_config expand to 000155, the purchase_suppressions expand
to 000156 and the contract to 000157, and update every reference: SQL
headers, store comments, fixtures and gate test versions. The gate error and
503 message now build the migration numbers from two constants.

* fix(api): answer the recommendations list with a 503 below the az_config expand
The list returned a generic 500 when the az_config migrations were missing.
Map ErrAZConfigMigrationNotReady to the same 503 the purchase paths return,
through one shared helper.

* fix(db): renumber the az_config migrations to 000157-000159 after #1241
Main now has 000155 and 000156 from #1241. Move the recommendations az_config
expand to 000157, the purchase_suppressions expand to 000158 and the contract
to 000159, with the gate constants, error text, fixtures and comments.

the message checks, the migration-version literals and comments move by
one.
