Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR changes billing identity, B-leg tracking, finalization, and database migration behavior. Current paths can still merge unrelated usage, omit legs needed for settlement, or leave finalization waiters blocked, with additional migration-readiness concerns. These are material billing correctness and availability risks, so the PR is not ready to merge until the runtime issues are fixed and remaining concerns are addressed or explicitly accepted.

- Around line 8-9: Update the baseline description in validation.md to reference
a reproducible commit SHA for the branch, or explicitly identify this PR’s merge
commit as the baseline instead of describing an uncommitted corrected tree.
- Line 44: Add a single trailing newline at the end of validation.md, without
changing its content, so the file complies with markdownlint MD047.
- Line 4: Correct the statement in validation.md to accurately reflect the
updated spec.json flags, including ready_for_implementation and the approval
flags, or revert those flag changes so the statement remains true.

Apply the same fix in
@.kiro/specs/billing-post-usage-correctness-hardening/validation.md at line 4:
Duplicate validation-record contradiction covered by the consolidated comment.
In `@internal/archtest/billing_correctness_ratchet_test.go`:
- Around line 273-291: Update TestBillingCorrectnessRatchetRuleNamesReferenced
to track each rule name in a set and fail when a name has already been seen,
while retaining the existing non-empty validation.
- Around line 107-139: Strengthen the accepting fixtures in
TestEvaluateBillingAttemptSequenceAuthorityAcceptsAuthoritativeAdapter and the
corresponding fixture by adding a negative control: evaluate a violating body in
the same temporary root and assert that findings are returned. Ensure the
fixture actually exercises the AST rule rather than passing because required
files are absent.
In `@internal/archtest/billing_correctness_ratchet.go`:
- Around line 162-174: Update scanFuncBodyForbiddenIdents so the
missing-function finding uses its passed rule parameter instead of
BillingCorrectnessRuleSequenceAdapterAuthoritative, ensuring callers such as
EvaluateBillingCustomerOperatorIndependence report the appropriate rule.
- Around line 151-174: Make all billing ratchets fail closed on missing or
unparsable targets: in internal/archtest/billing_correctness_ratchet.go:151-174,
update scanFileForbiddenIdents, scanFuncBodyForbiddenIdents, and
scanStructFieldNamesForbidden to return findings or errors and propagate them
through the Evaluate* functions; in
internal/archtest/billing_sequence_ratchet.go:12-35, emit a finding when both
candidate files are unreadable; in
internal/archtest/billing_state_ownership_ratchet.go:26-33, emit a finding when
os.ReadDir fails; and in
internal/archtest/billing_independence_ratchet.go:39-50, emit a finding when
resolver.go cannot be parsed.
In `@internal/archtest/billing_sequence_ratchet.go`:
- Around line 59-70: Update the sequence-source validation in the relevant AST
scan to accept selector expressions whose field is either AttemptSeq or Seq,
preserving the existing requirement that the selector receiver is an identifier.
Keep rejecting inline expressions and unrelated fields, and align the accepted
sources with scanLatestAcceptedUsesPersistedSequence.
- Around line 123-137: Replace the literal strings.Contains check in
scanLatestAcceptedUsesPersistedSequence with an AST-based inspection of the
parsed rating.go source. Detect a live binary comparison whose left and right
operands are selectors accessing Seq, regardless of local variable names,
spacing, or equivalent extraction into a helper; retain the existing RuleFinding
when no such comparison is found.
In `@internal/archtest/billing_state_ownership_ratchet.go`:
- Around line 108-114: Update isBillingCallIDKeyExpr and isBillingCallIDKeyedMap
to recognize *ast.Ident keys named BillingCallID, and resolve declared aliases
in the scanned package before deciding whether a map is BillingCallID-keyed.
Preserve selector-based detection while ensuring local aliases and same-package
identifiers trigger both map guards.
- Around line 34-51: Update the scan in the billing registry ratchet to detect
identifiers rather than raw source text: parse each production file with
parseProductionFile, collect symbols using collectIdentNames, and match
billingCorrectnessLifetimeRegistryIdents against those identifiers. Preserve the
existing finding and file-filtering behavior while ignoring comments and string
literals.
In `@internal/core/billing/sequence_contract_test.go`:
- Around line 83-109: Update
TestCallLegUsageLegacyMissingSequenceKeepsV1Fingerprint to use a fixed valid
BillingCallID for the AttemptSeq == 0 fixture and assert sealed.Fingerprint
equals the known hexadecimal v1 fingerprint. Keep the existing self-replay and
v1-versus-v2 conflict assertions, but add the golden-value check so persisted
legacy rows remain compatible with GetCallLegUsage.
In `@internal/core/runtime/billing_call_state_red_test.go`:
- Around line 69-75: Add an assertion in the test covering the two independent
preparations to verify prep1.billingCallID and prep2.billingCallID are
different, alongside the existing distinct-state and state-to-request checks.
Use the existing test failure style and preserve the current callID equality
assertions.
In `@internal/core/runtime/billing_collector.go`:
- Around line 205-221: Update ensureBillingCallState so a failed
billing.NewBillingCallID call does not assign a fabricated value such as
"synthetic-call-id" to billingCallID; preserve the empty/invalid ID and let the
existing validation in the billing persistence flow reject it.
- Around line 168-203: Update billing finalization to always close each cached
entry’s done channel via deferred cleanup in billingCallState.finalizeOnce,
including when finalizeFn panics, so waiters are released. In
callFinalizeBilling, invoke be.FinalizeBilling through safety.CallValue using
safety.BoundaryBackend and the operation name "backend_finalize_billing".
In `@internal/core/runtime/billing_leg.go`:
- Around line 268-281: Apply the same positive attempt-sequence guard used by
appendIndependentCallLeg before both B-leg allocation calls in recordBillingLeg
and executor_open_attempt.go: only allocate or freeze a B-leg when Seq is
greater than zero, and skip the allocation otherwise so JoinCompleteCall is not
left with an unappendable leg.
In `@internal/core/runtime/billing_post_output_failure_test.go`:
- Around line 17-25: Update mockFailingAppender to track invocation counts for
AppendCallUsage and AppendCallLegUsage, incrementing the corresponding counter
on each call. After lipapi.Collect, assert both counters are nonzero so the test
verifies both persistence appenders execute while their failures remain isolated
from the client stream.
In `@internal/core/runtime/executor_recv_loop.go`:
- Line 350: Update the replacement attemptOpenParams construction to include
billingCallState: s.billingCallState, alongside the existing billingCallID, so
replacement opens propagate the request-owned billing state through the same
path as initial opens.
In `@internal/core/runtime/parallel_race.go`:
- Around line 42-48: Remove the unused parallelLeg.callID field, along with its
initializer and test fixture assignment; leave the other parallelLeg fields and
behavior unchanged.
In `@internal/infra/billingcompose/catalog_test.go`:
- Around line 491-511: Update the test setup for unpublished in the catalog
pricing override case so at least one pricing rate differs from
catalogPricing(), then keep the existing CustomerRatingSnapshots assertion
against that distinct value. Ensure the assertion can distinguish the override
body from the default pricing body and still verifies the expected override
resolution.
In `@internal/infra/billingcompose/phase0_red_test.go`:
- Around line 12-14: Rename the tests to describe their asserted behavior: use
names equivalent to TestResolveCallRating_MixedModelPricingKeepsOverrides and
TestResolveCallRating_MissingOperatorRateDoesNotBlockCustomerRating. In both
test bodies, remove stale comments describing “current code” or the former
defect while preserving the existing expected-value arithmetic and assertions.
In `@internal/infra/billingstore/20260828000000_billing_usage_leg_sequence.go`:
- Around line 36-40: Update the PostgreSQL statements in the migration to create
usageLegCallAttemptSeqIndex concurrently, preserving its uniqueness and
idempotent behavior; rely on the existing non-transactional execution path so
PostgreSQL accepts the concurrent index build.
- Around line 44-52: Replace the broad error-text suppression in the migration’s
statement loop with a deterministic column-existence query against SQLite’s
catalog. Skip only the relevant ADD COLUMN operation when that column already
exists, retain IF NOT EXISTS for index creation, and propagate every other DDL
or catalog-query error instead of matching error strings.
In `@internal/infra/billingstore/call_leg_usage_store.go`:
- Around line 72-77: Update the withAccountTx retry classification to check
ErrLegAttemptSequenceConflict explicitly before the generic isUniqueViolation
check, returning it as a wrapped error that preserves errors.Is matching while
retaining the driver error. Add a regression test asserting the conflict
performs exactly one attempt and errors.Is returns true.
In `@internal/infra/billingstore/legacy_sequence_worker_test.go`:
- Around line 199-229: The test around ProcessOnce must assert its expected
outcome instead of only logging errors: verify errors.Is(err,
billing.ErrBillingAttemptSequenceUnknown) when ambiguity is returned, or require
nil if reconcile_required is handled successfully. Add a balance assertion for
the settled Cases A and B using the customer-facing account balance, while
retaining the existing status checks only as supplementary coverage.
In `@internal/infra/billingstore/store.go`:
- Around line 140-141: Add a PostgreSQL schema-verification query alongside the
existing usage-leg column and index checks to confirm
UsageLegSequenceMigrationName is recorded in bun_billing_migrations. Use the
existing migration-history verification pattern and preserve the current column
and unique-index checks.

- Around line 161-176: Update finalizeCacheKey to return an empty string when
BLegID, ALegID, Backend, and Model are all blank after trimming, while
preserving the existing key format for inputs with any identifying field. This
keeps the direct-execution branch in billingCallState.finalizeOnce reachable and
prevents identifier-less inputs from sharing a cached finalization result.

Learning: In this repository, when defining unexported Go `context` key constants of type `ctxKey int` (e.g., `const ( kFoo ctxKey = iota + N )`), preserve the `iota + <offset>` pattern and keep the existing `<offset>` values rather than simplifying to plain `iota`. These per-package offsets are part of the repo-wide convention to avoid key collisions across packages, and each such constant set should include a short explanatory comment (for example: “offset avoids collision with other packages' context keys”).

Make billing finalization panic-safe, fail closed without durable call identity, preserve replacement attempt state, and guard allocation on missing sequences. Strengthen append, migration, model-pricing, worker, and customer-balance regression evidence while keeping the exposure LOC ratchet green.
Fail closed on missing targets, recognize persisted sequence selectors with AST checks, cover BillingCallID aliases, strengthen fixture negative controls, and pin the legacy v1 fingerprint.
