fix(accounts): keep a service override's other fields when one field is edited - #1788
Editing one field of an account service override in Settings cleared the override's other fields. The UI sends one field per PUT (payment, term, coverage or enabled). buildServiceOverride built a fresh row from only the request's fields, and the upsert overwrites every column. So, for example, changing Term set payment, coverage and enabled to inherit and cleared every include/exclude filter. The response was still 200 with a success toast. Cleared exclude filters widen what can be bought.
Fix
8068716d:PUT /api/accounts/{id}/service-overrides/{provider}/{service} now merges the body over the stored row, presence-aware, the same pattern as mergeServiceConfig.
A key absent from the body keeps the stored value.
An explicit null clears it to inherit.
A value replaces it.
With no stored row, only the sent fields are set, as before.
The term/payment combo check runs on the MERGED row, so an existing payment plus a newly sent term is checked as a pair.
The body's keys come from presentKeys (a malformed body is a 400), against the allowlist serviceOverrideOverlayKeys.
The OpenAPI description of the endpoint and its request schema, and the stale comment in override_transfer.go, now describe the merge.
894de652:presentKeys matches body keys case-insensitively (via bodyHasKey), as encoding/json binds them. Before, a body key "Term" was decoded but the overlay missed it. This also applies to PUT /api/config/service/..., which shares presentKeys: a differently-cased key there now counts as sent, consistent with what was decoded.
Tests
New file internal/api/handler_override_merge_test.go, written first.
Single-field PUT, per key (11 subtests). Start from an override with every field set: enabled, term, payment, coverage, ramp_schedule and all 6 include/exclude filters. Send one key and assert that key changed and every other field survives in what reaches the store.
Null clear, per key. Only that field is cleared.
Case-insensitive keys.
No stored row. Only the sent fields are set.
Combo on the merged row. A stored no-upfront payment plus a sent term of 3 is refused with 400, and nothing is saved.
Fail-before: with the new tests on the old merge behaviour, all 11 single-key subtests fail, all 11 null-clear subtests fail, and the case-insensitive and combo tests fail. Deletion probes, each failing tests:
an unconditional term guard;
dropping the copy of the stored row;
dropping a key from the allowlist.
Verification (local, macOS)
go test ./internal/api/ ./internal/config/ passes.
go test -tags integration ./internal/api/ -run Override passes.
golangci-lint v2.10.1 reports 0 issues.
Every pre-commit hook passed.
The frontend is untouched; the backend fix covers the UI's single-field PUTs.
Service-override updates now preserve stored values for omitted fields, while supplied values replace them. Send null to clear a field and inherit the global configuration.
Updates without an existing override set only the fields provided.
AWS term and payment options are validated together against the merged override before it is saved.
Bug Fixes
Concurrent partial updates no longer overwrite changes to other fields.
JSON field names are matched regardless of capitalization.
Documentation
Clarified how partial updates and null values affect service overrides, and how override imports differ from PUT requests.
presentKeys now reuses bodyHasKey, so a key spelled "Term" counts as sent,
the same way encoding/json binds it. Prepares the shared overlay for the
account service override PUT.

The Settings UI sends one field per PUT, but the handler built a fresh row
and the store upsert overwrote every column, so editing one field cleared
the rest. Overlay only the keys present in the body onto the existing row
(null clears, absent keeps), check the term/payment combo on the merged
result, and describe the semantics in the OpenAPI spec.
Closes#1775
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Account service override PUTs now preserve omitted fields, clear fields sent as null, and replace fields with supplied values. The handler validates the merged override and uses an atomic store operation to write and audit it.
The store adds a locked, audited read-merge-write operation. Tests cover merge errors and a competing writer.
Presence-aware API merge internal/api/handler_accounts.go, internal/api/handler_config.go, internal/api/handler_accounts_test.go, internal/api/handler_override_merge_test.go, internal/api/handler_present_keys_test.go, internal/api/coverage_extras_test.go
The handler distinguishes present keys from omitted keys, overlays request values on the stored row, and validates the merged term and payment. Tests cover omitted fields, explicit null, case-insensitive keys, empty lists, and invalid combinations.
Integration checks and documented semantics internal/api/handler_override_merge_integration_test.go, internal/api/openapi.yaml, internal/api/override_transfer.go
Integration tests check field preservation and concurrent partial updates. API documentation describes merge and null-clearing semantics. The transfer comment distinguishes import rows from sparse PUT requests.

Explanation
Directly linked issue #1775 requires a presence-aware merge for PUT /api/accounts/{id}/service-overrides/{provider}/{service}. Verified at head, in internal/api/handler_accounts.go: presentKeys(httpReq.Body, serviceOverrideOverlayKeys) detects sent keys. buildServiceOverride copies the stored row (*override = *existing), then overlayOverrideScalars and overlayOverrideSlices replace a field only when present[key] is true. An explicit null sets the field to nil (inherit). An absent key keeps the stored value. With no stored row, only sent fields are set. Requirement: combo check on the merged result. Verified: mergeAndValidateServiceOverride builds the merged row and runs combos.check on it before the write. Requirement: tests for single-field preservation, null clearing, and the merged combo check. The summary lists TestSaveAccountServiceOverride_SingleKeyKeepsOtherFields, _ExplicitNullClearsOnlyThatKey, and _ComboCheckedOnMergedRow in internal/api/handler_override_merge_test.go. I did not read the test bodies, so test coverage rests on the summary. The atomic read-merge-write (UpdateAccountServiceOverrideAtomic in internal/config/store_postgres_config_audit.go) runs the read under the advisory lock and FOR UPDATE, so concurrent single-field PUTs do not lose updates. This goes beyond #1775's literal text but supports the same merge requirement.
Full details: Out of Scope Changes check
Explanation
Changes outside the literal #1775 text: (1) presentKeys in internal/api/handler_config.go now matches keys case-insensitively. This helper also serves PUT /api/config/service. The change is needed so that the override merge detects a differently cased key that encoding/json already binds, and the PR description discloses the effect on the config endpoint. (2) UpdateAccountServiceOverrideAtomic, its interface entry in internal/config/interfaces.go, and the MockConfigStore method in internal/mocks/stores.go. These support the locked read-merge-write that the merge depends on. The helper extraction (lockAndReadOverride, writeOverrideAudited) keeps SaveAccountServiceOverrideAuditedTx behavior. (3) OpenAPI and override_transfer.go comment updates describe the new merge semantics. Each change connects to the override merge. No unrelated change was found in the reviewed diff. Note: the current PR description does not mention the atomic store method or the lock-based write, though the code and commit summaries include them. This is a documentation gap, not an out-of-scope change.

Cold review, which also serves as the design review. This verdict comes from code review only: a fleet resource freeze blocked the test and probe runs, which are pending the thaw.
Design: the merge semantics are right.
Presence comes from map[string]json.RawMessage (handler_config.go:369-380), and each field is gated on present[key] (handler_accounts.go:1252-1290). An absent key keeps the stored value, null clears it (every override column is nullable), and a value replaces it.
Case variants: presence is true if any case variant is present (bodyHasKey, handler_config.go:151), while the value is whatever encoding/json decoded (last key wins). Presence only gates and the value always comes from the decode, so the two agree.
The combo check runs on the merged row (handler_accounts.go:1212-1219), and a test covers it.
Creating with no stored row sets only the fields sent, so a new row gets no default excludes.
Tenant scope: requirePermission and requireAccountAccess run before the read, which is keyed on the authorized account id.
Blocking
Lost update: the merge reads the stored row outside the write's lock.
handler_accounts.go:1201 reads existing via GetAccountServiceOverride on the pool, with no transaction (store_postgres.go:4392-4404). It then merges (:1206) and runs the combo check (:1212) on that copy.
Only after that does SaveAccountServiceOverrideAuditedTx take pg_advisory_xact_lock and FOR UPDATE (store_postgres_config_audit.go:140-146), and it writes every column (:172-176).
Repro: stored {term:1, exclude_regions:[eu-west-1]}, with PUT A {"exclude_regions":["x"]} and PUT B {"term":3} running concurrently. Both merge onto the same base, and the later commit restores the other's old value. If B lands last, A's new exclusion is silently reverted with a 200, which widens what can be bought.
Fix: do the read-merge-validate-write inside the locked transaction (a store method taking a merge callback), prefetch the combo options before the transaction (as handler_config.go:498-501 does), and add a real-Postgres race test.
Non-blocking
Create Override modal (frontend/src/settings.ts:1775-1828, bulk at :1886): it sends only the fields that are set, so on a service that already has an override, omitted fields are now kept instead of cleared. That is the safe direction (it never widens), and openapi.yaml:4406 documents it.
Test gaps:
nothing covers [];
no real-store merge test (every new test mocks GetAccountServiceOverride);
the effect on PUT /api/config/service is covered only by the presentKeys unit test.
Pending the thaw
the race probe;
case-variant probes (mixed-case null and value, [], {});
fail-on-main;
deletion probes: fresh-row build, case-sensitive presence, combo check on the request, and the null-clear branch dropped;
Cold review; this also covers the design, as requested. I didn't write this change.
1. High: the merge reads the stored row outside the write transaction
The sequence in internal/api/handler_accounts.go is:
GetAccountServiceOverride reads the stored row on a pooled connection (:1201).
The merge runs over that snapshot (:1206).
The combo check runs (:1212).
Only then does the transaction open (:1223).
SaveAccountServiceOverrideAuditedTx does take pg_advisory_xact_lock and FOR UPDATE (internal/config/store_postgres_config_audit.go:139-150), but only after the merge has used the unlocked snapshot.
Scenario: PUT A {"exclude_types":["db.t3.micro"]} and PUT B {"term":3} both read R0. A writes R0 + exclude, then B writes R0 + term, which resets exclude_types to R0's value. Both return 200. The Settings page sends service saves in parallel (frontend/src/settings.ts:1886), and two admins can edit the same row.
Fix: do the read, merge and check under the lock, as the sibling endpoint already does since #1488. UpdateServiceConfigAtomic (internal/config/store_postgres.go:491, used at internal/api/handler_config.go:503-510) is the pattern: a locked FOR UPDATE read, merge, then write, with prefetchCommitmentOptions so no pooled connection is held inside the tx. For example, give SaveAccountServiceOverrideAuditedTx an apply callback, and run the merge plus the combo check (on a prefetched snapshot) inside it. Add an integration test that runs two concurrent single-field PUTs on the same override and asserts both fields survive. No test covers that today.
2. Low: the combo check misses an inherited term or payment (it predates this PR; a follow-up is fine)
handler_accounts.go:1212 checks only the override row. A {"term":3} over an override with no stored payment passes Payment="", so the check is skipped, even when the inherited global payment makes the effective pair unsupported.
3. Nit
frontend/src/settings.ts:735 and :1764 still mention applyOverrideScalars, which this PR removes.
Design assessment (the overlay semantics are sound)
Fields:config.AccountServiceOverride (internal/config/types.go:1468-1486) has 18 fields.
The 11 settings fields (Enabled, Term, Payment, Coverage, RampSchedule, and the six include/exclude lists) are each overlaid on presence (handler_accounts.go:1253-1290).
ID and CreatedAt are kept from the stored row (:1239).
AccountID, Provider and Service come from the path, and UpdatedAt is set to now.
The reflection test pins the allowlist to the request's json tags.
Absent, null, []: an absent key keeps the stored value, an explicit null clears it to inherit, and [] replaces with an empty list, as on main. None of these columns is NOT NULL.
Key-case collisions: a body with both exclude_types and Exclude_Types decodes into one field, last key wins, and presentKeys marks it present either way. Both use Unicode simple folding, so they agree. For PUT /api/config/service, only differently-cased keys change behaviour, and they're now overlaid as decoded. That endpoint's tests pass.
The combo check runs on the merged row in both the update and create paths, and returns a 400 without internal text.
Scope:requireAccountAccess (:1184) runs before the read, and the read and write use only the account in the path.
Verification at this head (scratch worktree, heavy-review-2.lock)
go build ./... and go vet pass.
Unit tests (api, config): 6437 pass, 0 fail, 1 skip.
combo checked on the request instead of the merged row;
drop case-insensitive keys;
forget the exclude_types branch;
reset CreatedAt.
A "drop the lock" probe doesn't apply, because the handler takes no lock around the merge (finding 1).
Red-before (the handler files reverted to the base): the single-key, null-clear, case-insensitive, merged-combo and presentKeys tests fail, because the stored fields come back nil.
Runtime confirmation of my CHANGES REQUESTED at 8068716. The verdict is unchanged, and the blocker is now reproduced.
The B1 lost update reproduces in 40 of 40 rounds. This is an integration probe against real Postgres. Each round resets the row to {term:1, payment:all-upfront, exclude_regions:[eu-west-1]}, then sends {"exclude_regions":["r-N"]} and {"term":3} concurrently through saveAccountServiceOverride. Both PUTs return 200 every time, and one change is lost every time. It is the read of existing at handler_accounts.go:1201, before the lock at store_postgres_config_audit.go:140-146. Please add this race test to the repo along with the atomic merge fix (the fix(config): make the service-config PUT read-merge-write atomic #1488 / UpdateServiceConfigAtomic pattern).
Everything else behaves as designed:
Case variants: last key wins and presence agrees, including EXCLUDE_REGIONS, mixed-case duplicates with null and value, and the ſ fold.
[] clears; {"enabled":null} clears only that field; {} and null are no-ops; a body of [] is a 400.
Fail-on-main: the PR's new tests fail on 6d986bc: SingleKeyKeepsOtherFields, ExplicitNullClearsOnlyThatKey, the case-insensitivity tests, ComboCheckedOnMergedRow, and the reflection guard (with a one-line compile shim).
Deletion probes: each is caught by its intended test: restore the wipe, case-sensitive presence, the combo check on the request, and the null-clear branch dropped.
Filtered runs:go test -run 'Override|ServiceConfig|PresentKeys' and the same with -tags integration (api and config) pass at head.
The PUT read the stored override on the pool, merged and checked the combo
on that copy, and only then took the advisory lock and FOR UPDATE to write
every column. Two single-field PUTs merged onto the same base and the later
commit reverted the other change (a lost exclusion widens what can be bought).
Add UpdateAccountServiceOverrideAtomic: lock, read, merge and audited write
in one transaction, sharing the lock/read and write helpers with
SaveAccountServiceOverrideAuditedTx. The handler prefetches the commitment
options before the transaction and merges and checks the combo inside it.
Refs #1775
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
New head 7480d451d5451056d05bfd5b10a4cdc085dab3c6, fixing the lost update that claude-darling and claude-qa-ui-4 found (both CHANGES REQUESTED at 8068716d; darling reproduced it 40/40 on real Postgres).
Fix (7480d451)
New store method.PostgresStore.UpdateAccountServiceOverrideAtomic(ctx, accountID, provider, service, audit, merge) runs, in ONE transaction:
the same advisory lock and FOR UPDATE read as the audited save;
merge(existing);
the audited write.
The lock-and-read and the write are shared helpers with SaveAccountServiceOverrideAuditedTx, so there is no duplicated SQL. A merge error rolls back and is returned unchanged. This is the fix(config): make the service-config PUT read-merge-write atomic #1488 / UpdateServiceConfigAtomic pattern.
Handler. The commitment options are prefetched BEFORE the transaction, so there are no pool reads while it holds the lock (Lambda pools are 3). Inside it, mergeAndValidateServiceOverride does the presence-aware merge and the term/payment combo check on the merged row, with no I/O. The pre-transaction read of the stored row is gone.
The combo 400 still surfaces.IsClientError unwraps with errors.As, and TestSaveAccountServiceOverride_ComboCheckedOnMergedRow asserts 400 through the new path.
Tests
The race test is darling's repro, TestOverrideMerge_ConcurrentSingleKeyPutsKeepBothKeys, on real Postgres, 40 rounds.
Each round resets the row to {term:1, payment:all-upfront, exclude_regions:[eu-west-1]}, then races {"exclude_regions":["r-N"]} against {"term":3}.
BOTH changes must survive.
It fails 40/40 with the handler reading and merging outside the lock, and passes with the fix.
TestOverrideMerge_SingleKeyPutKeepsOtherFieldsInStore: a one-field PUT over a full row through the real store keeps every other field.
EmptyListSetsEmptyNotNil: [] sets an empty list, distinct from null clearing it.
TestOverrideAtomic_MergeErrorAbortsUnchanged and TestOverrideAtomic_QueuesBehindCompetingWriter (internal/config).
Deletion probes, each failing tests:
dropping the advisory lock and FOR UPDATE: the race test fails, plus the audit queue tests;
wrapping the merge error: MergeErrorAbortsUnchanged fails.

Document that merge must not modify the row it receives.
The PostgreSQL implementation uses the same pointer for the pre-merge row and the merge input. If a callback changes that row and returns it, the audit compares identical snapshots and records no event. The interface comment does not state this requirement. The current handler does not trigger the failure because it copies the stored row before changing it.

Validate the effective term before the override combo check.
When a PUT sends "term": null, the merged term is nil and the check receives 0. commitmentOptsSnapshot.check returns nil for Term <= 0, so the stored override can pair the inherited global term with an override payment. Fixing this needs the global term in the merge step, which runs without I/O inside the locked transaction. This also affects the service-config PUT path. It predates this PR.

1798-1801: Trivial · Maintainability & Code Quality · Low value
Apply the store's same-key check to the mock's atomic update fallback.
The fallback saves the merged row without checking its key. PostgresStore.UpdateAccountServiceOverrideAtomic rejects a merged row whose AccountID, Provider, or Service differs from the path arguments. The current handler always sets the path key, so no present caller triggers the gap. A test that returns a mismatched merge result would pass against the mock and fail against PostgreSQL. The service-config mock already uses this check, so the change matches existing mock behavior.

Reloads the row with GetAccountServiceOverride.

Review comments at @internal/api/handler_override_merge_integration_test.go:
- Line 39: Add an end-to-end test in the real-Postgres override integration
tests that seeds a fully populated row using fullOverrideFor(f.acct.ID), sends a
null exclude_regions value through f.put, then reloads it with
GetAccountServiceOverride. Assert ExcludeRegions is cleared and every other
field still matches the seeded row.
Review comments at
@internal/config/store_postgres_config_audit_integration_test.go:
- Around line 152-154: Extend the failed-merge test after the
GetAccountServiceOverride assertion to count upsert audit events for f.account
and assert the count is zero, ensuring the merge failure leaves no audit event.
Review comments at @internal/mocks/stores.go:
- Around line 1798-1801: In the mock’s atomic update fallback, validate the
result of merge before calling SaveAccountServiceOverrideAuditedTx: reject a nil
row or one whose AccountID, Provider, or Service differs from the path
arguments. Match the key-validation behavior of
PostgresStore.UpdateAccountServiceOverrideAtomic.

Delta review against my CHANGES REQUESTED at 8068716. This verdict is from code review only. The fleet's lock priority queue held my test runs. I'll post the runtime results (the race test at head and against the reverted handler, a concurrent-first-create probe, and the deletion probes) once the queue is released. If any of them deviates, this approval is withdrawn.
B1 (lost update) is fixed:
One transaction.UpdateAccountServiceOverrideAtomic (internal/config/store_postgres_config_audit.go:157-180) runs the advisory lock, the FOR UPDATE read (lockAndReadOverride, :184-197), the merge and writeOverrideAudited in one WithTx. The handler no longer reads existing (handler_accounts.go:1200-1217).
Nothing slow under the lock. The combo options are prefetched before the transaction (:1203), and mergeAndValidateServiceOverride (:1225-1236) does no I/O.
Errors and audit. A merge error rolls back, and the audit "before" is the locked read. A returned row with a mismatched key is refused (:168). The combo 400 survives the %w wrap, because IsClientError uses errors.As.
Concurrent first create. The advisory lock is taken before the read even when no row exists, so a second creator waits and sees the first row. It can't surface a unique violation.
The tests are structured right:
The race repro is in-repo on real Postgres (handler_override_merge_integration_test.go), with 40 rounds that also assert the untouched payment survives.
There is a real-store single-key merge test.
The store tests show that a merge error aborts with no row, and that the merge queues behind a competing writer and sees its commit.
Non-blocking: the [] test (handler_override_merge_test.go, EmptyListSetsEmptyNotNil) runs on the mock, and its comment says [] "is not the same as null". The resolver treats them alike (internal/config/resolver.go:90, len(...) > 0): both inherit the baseline. That's safe; only the comment overstates the difference.
The read, merge and write now run in one transaction: internal/api/handler_accounts.go:1209-1212 passes a pure merge callback (mergeAndValidateServiceOverride, :1225) to UpdateAccountServiceOverrideAtomic (internal/config/store_postgres_config_audit.go:156), which takes the advisory lock and reads FOR UPDATE (:184-191), merges, checks the key and writes the audited upsert. The commitment options are prefetched before the transaction (:1203), so no pooled read runs inside it.
Race test, real Postgres: 20 of 20 runs pass at the head; with only the handler reverted to 8068716 it fails 5 of 5 (40 of 40 rounds lost).
Probes: 13 of 13 killed: replace instead of merge, null vs absent both ways, dropped combo check, combo checked on the request instead of the merged row (TestSaveAccountServiceOverride_ComboCheckedOnMergedRow fails), case-insensitivity, exclude_types branch, CreatedAt reset, FOR UPDATE removed, advisory lock removed, both removed, merge outside the transaction, and handler back to read-then-merge (InvalidCombo_Returns400 fails; race test 5 of 5 fail).
Suites (GOMAXPROCS=4, -p 2): build and vet pass; unit api+config 6438 pass, 0 fail; integration api+config 7855 pass, 0 fail.
Non-blocking:
internal/api/handler_accounts.go:1227: the combo check uses only the override's own term/payment, not inherited values. Predates this PR; fine as a follow-up.
frontend/src/settings.ts:735, :1764: comments still name the removed applyOverrideScalars.
The PUT used the path spelling of the account id as the lock and merge key,
so an upper-case and a lower-case first PUT could race and drop keys. It now
uses the stored account id. The spec summary and nullable fields are
corrected.

Delta review of the fix round: the case-canonical lock and merge key, plus main merged in. It is minimal and scoped because of fleet quota limits, and runs-backed.
Canonical key:handler_accounts.go:1190 sets accountID = account.ID, the stored id from requireAccountAccess. The advisory-lock key and the FOR UPDATE read in UpdateAccountServiceOverrideAtomic both use it, so every spelling of one account id maps to one lock and one row.
Provider and service were already canonical: the path parser accepts lowercase only (:1830-1834).
account_service_overrides.account_id is a UUID column (migrations/000011_cloud_accounts.up.sql:80), so no mixed-case rows can exist and no migration is needed.
Integration tests on real Postgres pass:TestOverrideMerge_ConcurrentSingleKeyPutsKeepBothKeys and TestOverrideMerge_ConcurrentFirstPutsAcrossIDSpellingsKeepBothKeys.
Mutation: dropping the canonicalization line makes the case-variant test fail ("40 of 40 rounds lost one of two concurrent first PUTs"), so the test guards the fix.
This also completes the runtime proof that my earlier approval at 7480d45 left pending: the in-repo race tests now pass on real Postgres. I read the main merge (5719905) and the openapi summary and nullable edits; neither touches this path.
Delta review of 7480d45..bbc9d18 (minimal, under quota).
5719905 merges origin/main with no hand resolution (empty remerge diff).
internal/api/handler_accounts.go:1184-1190: accountID = account.ID after requireAccountAccess (scoping.go:32-49 returns the stored account, non-nil on success), so the store's lock key (store_postgres_config_audit.go:186) and the merged row key use the canonical id for every spelling of the path id.
TestOverrideMerge_ConcurrentFirstPutsAcrossIDSpellingsKeepBothKeys (real Postgres, lower- and upper-case first PUTs raced) and TestSaveAccountServiceOverride_UsesCanonicalAccountID pass at the head (one run, GOMAXPROCS=4 -p 2).
internal/api/openapi.yaml: summary now says "Create or update"; every AccountServiceOverrideRequest property is nullable, matching the null-clears semantics described there.
Delta approvals at this SHA: claude-darling and claude-qa-ui-4.
CI green at this SHA; 0 unresolved threads; merge state CLEAN; no migration or terraform changes.
Combo re-test: origin/main e9c90b9 merged with bbc9d18 (local, macOS, throttled). Build and vet pass; unit ./internal/api/ ./internal/config/ pass; integration (-tags integration, -run 'Override|AccountService|CombinedPlan') passes for both packages.
Fail-before for the fix round: the case-spelling race test lost a PUT in 40/40 rounds and the canonical-id unit test saw the upper-case id; both pass after the fix.
Not verified against a real cloud account (none needed for this handler path).

Closes #1775
Problem
Editing one field of an account service override in Settings cleared the override's other fields. The UI sends one field per PUT (payment, term, coverage or enabled).
buildServiceOverridebuilt a fresh row from only the request's fields, and the upsert overwrites every column. So, for example, changing Term set payment, coverage and enabled to inherit and cleared every include/exclude filter. The response was still 200 with a success toast. Cleared exclude filters widen what can be bought.Fix
8068716d:PUT /api/accounts/{id}/service-overrides/{provider}/{service}now merges the body over the stored row, presence-aware, the same pattern asmergeServiceConfig.nullclears it to inherit.presentKeys(a malformed body is a 400), against the allowlistserviceOverrideOverlayKeys.override_transfer.go, now describe the merge.894de652:presentKeysmatches body keys case-insensitively (viabodyHasKey), asencoding/jsonbinds them. Before, a body key"Term"was decoded but the overlay missed it. This also applies toPUT /api/config/service/..., which sharespresentKeys: a differently-cased key there now counts as sent, consistent with what was decoded.Tests
New file
internal/api/handler_override_merge_test.go, written first.no-upfrontpayment plus a sent term of 3 is refused with 400, and nothing is saved.AccountServiceOverrideRequest's json tags must equal the allowlist and the test table, so a new field can't be silently dropped. This covers part of the audit(internal): API* → internal-request adapter field-drop hygiene (followup to #893) #19 test gap.Fail-before: with the new tests on the old merge behaviour, all 11 single-key subtests fail, all 11 null-clear subtests fail, and the case-insensitive and combo tests fail.
