* parity-sweep: tick stepfunctions complete

* parity(ssm): fix parity, performance, and leak issues

Parity:
- Replace shared package-level mock KMS key with per-instance random
  AES-256 key (newInstanceGCM). Each InMemoryBackend now generates its
  own key so ciphertexts are not interchangeable across backend
  instances, matching AWS KMS key-isolation semantics.

Performance:
- Remove O(n) expireCommandsLocked call from SendCommand write path;
  expired-command eviction is the janitor's job (sweepExpiredCommands
  runs on a configurable interval). SendCommand is now O(1) again.
- Remove paramNamesSorted sorted-slice index and its O(n) insert on
  every PutParameter. Replace collectPathParamsSorted (binary-search)
  with collectPathParams (linear scan + sort-at-read). PutParameter
  write path drops from O(n) to O(1); GetParametersByPath is O(n log n)
  which is acceptable for an emulator. Also fixes a silent post-Restore
  bug where GetParametersByPath returned empty (sorted slice was never
  rebuilt from the snapshot).

Leaks:
- Add cleanupEmptyParamRegion: after DeleteParameter / DeleteParameters
  removes the last entry in a region, the empty parameters/history/tags
  inner maps are deleted so they don't accumulate indefinitely.

Tests:
- Update leak_test.go: TestSendCommand_PrunesExpiredCommands →
  TestJanitor_PrunesExpiredCommands; verify janitor sweeps expired
  commands and that SendCommand no longer does so.
- Add parity_fixes_test.go with table-driven tests for all four fixes:
  per-instance key isolation, self-roundtrip encryption, linear-scan
  path lookup (sort order, recursive/non-recursive, no-match), and
  region-map cleanup via single and batch delete.

* fix(iam): parity fixes — distinct error sentinels, O(1) sorted list indexes, fast policy lookup

Parity:
- Give each NoSuchEntity sentinel a distinct message suffix (user, role, policy,
  group, access key, instance profile, inline policy, SAML provider, OIDC provider,
  login profile) so callers can identify the missing resource type via .Error()
  inspection without relying on errors.Is pointer identity alone. HTTP error code
  is still "NoSuchEntity" matching AWS.
- Fix collectNamedEntityPolicies to use policyByARN map for O(1) ARN → name
  resolution instead of the previous O(n) linear scan over all policies.

Performance:
- Add sortedUserNames, sortedRoleNames, sortedPolicyNames, sortedGroupNames,
  sortedIPNames []string indexes to InMemoryBackend, maintained via binary-search
  insert/delete on every create/delete. ListUsers, ListRoles, ListPolicies,
  ListGroups, ListInstanceProfiles now paginate via pageFromSortedNames which
  resolves the base64-encoded integer marker token in O(1) and builds each page
  in O(k) (page size), eliminating the previous O(n log n) sort rebuild on every
  list call.
- rebuildIndexesLocked and Purge both rebuild sorted name indexes via
  rebuildSortedNames, keeping persistence and compaction paths consistent.

Tests:
- TestParityIAM_ErrorSentinelDistinctness: table-driven, verifies each sentinel
  has a unique .Error() string.
- TestParityIAM_ErrorSentinelUniqueness: all pairs are not-equal via errors.Is.
- TestParityIAM_ErrorSentinelWrapping: backend errors wrap the correct sentinel.
- TestParityIAM_HandlerNoSuchEntityCode: handler returns 400 + "NoSuchEntity"
  for all not-found operations.
- TestParityIAM_SimulatePrincipalPolicy: real policy evaluation (allow, deny,
  no policy, explicit deny overrides allow).
- TestParityIAM_CredentialReportColumns: all 22 AWS-required CSV columns present.
- TestParityIAM_ListPaginationSortedOrder: multi-page pagination stays sorted.
- TestParityIAM_SortedIndexMaintainedAfterDelete: index correct after deletion.

* parity(ssm): complete parity.md findings — region cleanup, MW executions, generic cleanup helper

- Add cleanupEmptyInnerMap[V any] generic helper that removes a region key
  from any two-level map when the inner map becomes empty; replaces the
  three-field cleanupEmptyParamRegion body with calls to this helper
- Wire cleanup to all delete paths: DeleteActivation, DeleteAssociation,
  DeregisterTargetFromMaintenanceWindow, DeregisterTaskFromMaintenanceWindow,
  DeleteMaintenanceWindow, DeletePatchBaseline, DeleteOpsItem, DeleteOpsMetadata,
  DeleteInventory, DeleteResourceDataSync, DeleteResourcePolicy, DeleteDocument
- Janitor sweepExpiredCommands now cleans up commands/commandInvocations maps
  after eviction so empty region buckets do not accumulate
- GetMaintenanceWindowExecution/Task/Invocation now populate StartTime, EndTime,
  StatusDetails, TaskARN, TaskType, Priority, MaxConcurrency, MaxErrors,
  InvocationID, WindowTargetID from stored window/task data
- Expand three MW execution output types with full AWS-accurate fields
- Fix handler_batch2_test to create a real window before GetMaintenanceWindowExecution
- Add TestGetMaintenanceWindowExecution_FullOutput and TestOtherMapsRegionCleanup
  table-driven tests covering new behavior (all t.Parallel)
- Zero golangci-lint issues; struct field order corrected by fieldalignment

* parity(ssm): real AWS-accurate SSM emulation — implement stubbed ops + fixes

~120 stubbed ops given real state mutation (ResourceDataSync, Inventory, Activations, maintenance windows w/ MaxConcurrency/MaxErrors/InvocationID/WindowTargetID), GetParametersByPath prefix index, param/doc/command history AWS caps, MaxResults bounds. Table-driven tests, 0 lint.

* parity(iam): real AWS-accurate IAM emulation — fix parity.md findings

Policy-eval correctness, pagination/validation fidelity, sub-ops. Table-driven tests, 0 lint.

* parity(glue): real AWS-accurate Glue emulation — implement stubbed ops

20+ empty-struct stubs given real data/state (GetBlueprintRun, GetPlan, ImportCatalogToGlue, column-statistics, schema-versions-diff, usage-profile), StopCrawler STOPPING->READY reconcile. Table-driven tests, 0 lint.

* parity-sweep: tick ssm, iam, glue

* parity(kms): fix cache staleness, lastUsage leak, perf O(n) clear

Four parity/leak/perf fixes for services/kms:

Parity: keyIDResolutionCache not invalidated on DisableKey /
ScheduleKeyDeletion. Alias→keyID entries cached before a key state
change persisted in the cache, allowing stale hits to bypass the
aliasesStore and return the old keyID. Fix: call evictAliasesFromCache
(O(aliases-for-key)) in both operations.

Performance: clearResolutionCache used sync.Map.Range+Delete (O(n)) and
was called on every alias mutation (Create/Update/Delete). Fix: change
keyIDResolutionCache to *sync.Map so clearResolutionCache swaps the
pointer in O(1); replace full-cache clears in alias mutations with
single targeted Delete calls; remove the post-sweep clearResolutionCache
call from sweepExpiredKeys since purgeKey now evicts targeted entries.

Leaks: purgeKey in the janitor deleted keys, aliases, grants, and key
material but never removed the corresponding lastUsage sync.Map entry,
causing unbounded growth. Fix: add lastUsage.Delete in purgeKey.

Tests: table-driven tests in parity_fixes_test.go covering all four
fixes; test helpers (ResolutionCacheLen, ResolutionCacheHas,
LastUsageExists) added to export_test.go.

* parity(cloudwatch): real AWS-accurate CloudWatch emulation — fix parity.md findings

Parity:
- GetMetricWidgetImage: return minimal valid 1×1 PNG (base64) instead of empty stub
- ListAlarmMuteRules: add backend method + wire handler to return stored rules
- ListManagedInsightRules: add backend method filtering ManagedRule=true; wire handler
- PutManagedInsightRules: parse ManagedRules.member.N.* and store with ManagedRule=true
- EC2/AutoScaling alarm actions: log explicit warnings instead of silent no-op

Performance:
- SweepExpiredMetrics: two-phase sweep (read-lock snapshot → out-of-lock filter → write-lock apply)
  avoids holding global write lock for full O(series×points) scan
- PutMetricData: extract storeDatum helper; move stream delivery timestamp update to a
  second, shorter write-lock acquisition outside the main metrics write section
- Extract sweepScanCandidates / sweepApplyResults / hasExpiredPoint helpers to reduce
  cognitive complexity below gocognit threshold

Leaks:
- deleteResourceTags: call t.Close() before removing from map to deregister the
  per-resource Prometheus lockmetrics entry and prevent unbounded registry growth

Tests: new parity_test.go with table-driven tests for all fixed ops

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* parity(ecs): real AWS-accurate ECS emulation — implement daemon ops, service revisions, state changes

- Implement all 12 daemon CRUD operations with full state tracking (CreateDaemon,
  DeleteDaemon, DescribeDaemon, ListDaemons, UpdateDaemon and task-def/deployment/revision ops)
- Track service revisions on CreateService and UpdateService; implement DescribeServiceRevisions
- Fix DiscoverPollEndpoint to return region-specific endpoints (was hardcoded)
- Implement SubmitTaskStateChange, SubmitContainerStateChange, SubmitAttachmentStateChanges
  with cluster/task validation instead of no-op stubs
- Fix enrichCluster O(n) task scan: cache RunningTasksCount/PendingTasksCount on Cluster
  and maintain counters at every state transition (RunTask, StopTask, startTasksOutsideLock)
- Add Backend interface methods for all new ops; add GetRegion() on InMemoryBackend
- Add region field to Handler populated from backend for regional URL generation
- 19 table-driven tests covering all new operations and counter correctness

* parity(cloudwatch): real AWS-accurate CloudWatch emulation — fix parity.md findings

findGrantByToken token index (O(1)), metric-datapoint ring buffer, alarmHistory cross-alarm cap. Table-driven tests. build+vet+test+lint green.

* parity-sweep: tick cloudwatch

* refactor(kms): split ReEncrypt into helpers to satisfy funlen lint

Extract reEncryptDecrypt (source key lookup, validation, decrypt) and
reEncryptEncrypt (dest key lookup, validation, encrypt) so ReEncrypt
itself is ~34 lines, well under the 100-line funlen limit.

No behaviour change.

* parity(kms): real AWS-accurate KMS emulation — fix parity.md findings

* parity(sts): real AWS-accurate STS emulation — fix parity.md findings

GetCallerIdentity InvalidClientTokenId (400 not 403), session TOCTOU fix, session-store sweep/leak bound. Table-driven tests. build+vet+test+lint green.

* parity-sweep: tick sts

* fix(sqs): parity/perf — region isolation, janitor skip-idle, MD5 reuse

Parity:
- lookupQueueByURL: remove O(n) URL-string fallback scan that defeated region
  isolation; always resolve via effectiveRegion(region)+name composite key so a
  wrong-region request returns not-found instead of blindly finding the queue.

Performance:
- pruneState: replace full-capacity snapshot (len(b.queues)) with a filtered
  collection that skips queues with no hasActivity flag set. A new atomic.Bool
  field on Queue is set on every SendMessage and cleared by pruneState when the
  queue becomes fully idle, so idle queues are skipped on subsequent janitor
  ticks without lock contention.
- ReceiveMessage handler: when filterMsgAttrs returns the full attribute set
  (len(returnedAttrs)==len(msg.MessageAttributes)), reuse msg.MD5OfMessageAttributes
  computed at send time instead of re-sorting and re-hashing on every receive.
  Subset requests still recompute to produce a correct scoped digest.

Tests (table-driven):
- TestLookupQueueByURL_RegionIsolation: wrong-region receive returns error
- TestLookupQueueByURL_CrossRegionURLScanEliminated: east queue invisible to west
- TestPruneState_SkipsIdleQueues: 50 idle queues, active-queue message expires
- TestPruneState_ClearsActivityFlagWhenIdle: flag cleared after full drain
- TestComputeMD5OfMessageAttributes_FullSetUsesPrecomputed: all/.*/ exact-full variants
- TestReceiveMessage_MD5Consistency: subset MD5 matches SQS wire-format spec

* parity-sweep: tick organizations

* fix(integration): STS/CloudWatchLogs/ECR runtime regressions (go-ds2ym)

DecodeAuthorizationMessage decodes any valid base64 (not just self-issued), AssumeRoleWithSAML creds/Issuer/NameQualifier, CloudWatchLogs Insights, ECR GetAuthorizationToken. Unit+lint green.

* fix(integration): correct STS DecodeAuthorizationMessage/AssumeRoleWithSAML + ECR GetAuthorizationToken

Supersede the incomplete first attempt: STS decodes any valid base64 (not only self-issued), SAML accepts non-XML base64 assertions, ECR returns stable base64(AWS:dummy-password). Unit tests realigned. CloudWatchLogs Insights still pending.

* fix(integration): CloudWatchLogs StopQuery allows stopping instant-Complete queries

gopherstack runs Insights queries synchronously, so a query is already Complete
when a client calls StopQuery — the old running-state guard rejected it. StopQuery
now transitions any non-cancelled query to Cancelled (matches TestIntegration_CloudWatchLogs_Insights).

* parity(batch): real AWS-accurate Batch emulation — fix parity.md findings

- NewInMemoryBackend(accountID, region) — ARNs now use the injected
  region/account instead of hardcoded config.DefaultRegion constants
- groupsByARN index — GetGroupByARN/UpdateGroupByARN/DeleteGroupByARN
  go from O(n) linear scan to O(1) map lookup
- Insight detection — PutTraceSegments now calls detectInsights();
  ACTIVE insights auto-open when per-service fault rate ≥ 5% over a
  60-second window and auto-close when the rate normalises
- ListRetrievedTraces — handler now returns real Segments[]
  (Document + Id + computed Duration) instead of empty arrays

* parity(dax): fix AZ-indexing, RebootNode recovery, pending-reboot, error mapping

- IncreaseReplicationFactor: guard used raw loop index i instead of
  offset j=i-existingCount, silently ignoring caller-supplied AZs
  when the cluster already had nodes
- RebootNode: empty NodeId returned ErrNodeNotFound; AWS returns
  InvalidParameterValue. Add recovery goroutine that restores node
  status to available after 1s, mirroring real DAX behaviour
- UpdateParameterGroup: did not mark dependent clusters pending-reboot
  or populate NodeIDsToReboot; now scans all clusters using the group
- writeBackendError: flattened every DynamoDB error to ValidationException;
  now maps ConditionalCheckFailed, ResourceNotFound, TransactionCanceled,
  TransactionConflict, and ProvisionedThroughputExceeded to their
  correct DAX error codes
- handleGetItem: decoded ConsistentRead from the wire but discarded it
  with _; now passes it through to the DynamoDB backend
- nameRef: O(n²) linear scan replaced with O(1) reverse map
- schemaFor: cache was never invalidated on table drop/recreate;
  now fetches live on every call for correctness

* fix(sqs): hold q.mu around computeDynamicAttributes in GetQueueAttributes

GetQueueAttributes read q.messages, q.delayedCount, and q.inFlightMessages

This caused a data race detected by -race in TestIntegration_Lambda_SQS_ESM.

* parity(pinpoint): fix handleCreateApp error mapping

Before this change, any error from Backend.CreateApp was unconditionally
mapped to HTTP 500. Other handlers (GetApp, DeleteApp, etc.) already
dispatched errors correctly. This fix brings CreateApp into line:

- ErrInvalidParameter → 400 BadRequestException
- ErrConflict         → 409 ConflictException
- ErrNotFound         → 404 NotFoundException
- other               → 500 InternalServerErrorException

Add handler_parity_test.go with table tests covering:
- CreateApp input validation returns 400 (not 500)
- GetApp/DeleteApp for nonexistent IDs return 404 with NotFoundException
- CreateApp response shape includes Id, Arn, Name, CreationDate
- GetApps reflects all created apps
- DeleteApp removes app from subsequent list

* feat(eventbridge): fix parity issues — opaque tokens, per-account quota, ListEventBuses Limit, Shutdown cancellation, tag leak

- paginate: encode next-page tokens as base64 so they are opaque to callers,
  matching real AWS behavior; parseNextToken retains a plain-integer fallback
  for tokens produced before this change
- paginateN: new generic helper that respects a caller-supplied page size (0 = default 100)
- ListEventBuses: add limit parameter to StorageBackend interface and InMemoryBackend
  so the Limit field from API requests is honored instead of always paging at 100
- CreateEventBus quota: count custom buses across all regions in b.buses to enforce
  the per-account limit (200), not per-region
- StartWorker: derive a cancellable context for scheduler and archiveJanitor goroutines;
  store the cancel func so Shutdown can terminate both workers before closing the backend
- DeleteEventBus / DeleteRule: describe the resource before deletion to obtain its ARN,
  then call clearResourceTags so the handler tags map does not grow without bound

- streams_ops.go: ListStreams sets StreamLabel from ARN (not "latest")
- streams_ops.go: add streamLabelFromARN helper
- table_ops.go: CreateTable and UpdateTable set StreamCreatedAt and pass it

* feat(audit): back RDS Data API with a real in-memory SQL engine toward LocalStack parity

The RDS Data API previously executed no SQL: ExecuteStatement returned an
empty record set and ExecuteSql always reported 0 rows updated, so the
service modelled the control plane only. This closes the #1 functional gap
versus LocalStack (which runs a real database behind the Data API).

- Add services/rdsdata/engine.go: a pure-Go (modernc.org/sqlite, no cgo)
  per-(region, resourceARN) in-memory SQL engine. Each Aurora resource gets
  an isolated shared-cache database pinned by a keep-alive connection, scoped
  by an engine-instance nonce so two backends never alias the same store.
- ExecuteStatement / BatchExecuteStatement / ExecuteSql now run statements for
  real, returning genuine records, column metadata and update counts. Anything
  the engine rejects (e.g. DML against a table that was never created) degrades
  to the historical empty-success envelope, preserving backward compatibility.
- BeginTransaction opens a matching engine transaction; Commit/Rollback finalize
  it, giving real atomic visibility for statements tagged with a transactionId.
- Restore replays the recorded statement log so table state survives a
  snapshot/restore cycle (best-effort for parameterised/trimmed statements).
- README: correct the stale "image-based only" Lambda claim — Zip packaging
  across the managed runtimes is supported and already implemented.

Adds engine_test.go (round-trip, isolation, transactions, batch, snapshot
replay, reset, lenient fallback); package coverage 89.6%. Existing unit and
integration tests are unchanged and still pass.

* feat(audit): deepen API Gateway (HTTP API routing, VTL, proxy integrations) + KMS (key lifecycle, grants, rotation) toward LocalStack parity

* test(terraform): RDS Data engine round-trip — create cluster, add data, query, destroy

Adds an `engine_roundtrip` case to TestTerraform_RDSData that provisions an
Aurora cluster via Terraform, then drives the full Data API data path against
it: CREATE TABLE, INSERT rows, and SELECT them back asserting the real
round-tripped values (long and string fields) plus column metadata. The
terraform harness tears the cluster down on cleanup, so the case covers
create-engine -> add-data -> query -> destroy end to end and exercises the new
in-memory SQL engine through the SDK + Terraform path.

* feat(audit): deepen STS (AssumeRole variants, credential issuance, caller identity) + CloudWatch (metric aggregation, alarm state machine) toward LocalStack parity

* feat(rdsdata): bind named parameters in ExecuteStatement

ExecuteStatement previously dropped bound parameters — only the batch path
threaded them — so the common Aurora Data API pattern (e.g. `WHERE id = :id`)
fell back to the empty-result envelope. The backend method now accepts variadic
SQLParameters (keeping every existing call site source-compatible) and the
handler forwards req.Parameters, so named placeholders are substituted on both
the write and read paths.

Adds a parameterised round-trip test (insert with :id/:name, then select by :id).

* feat(audit): deepen EventBridge (event-pattern matching, target delivery, scheduled rules) toward LocalStack parity

* fix(test): RDS FullLifecycle — set ApplyImmediately for the instance-class change

TestSDK_RDS_FullLifecycle modified DBInstanceClass without ApplyImmediately and
asserted the new class took effect immediately. Since RDS ModifyDBInstance was
deepened to defer instance-class changes to PendingModifiedValues (AWS-accurate
behaviour when ApplyImmediately is unset), the live class correctly stayed
unchanged and the assertion failed. The test now passes ApplyImmediately=true,
which is how a real client forces an immediate instance-class change. Pre-existing
failure on the parity-sweep base, unrelated to the rdsdata engine change;
surfaced by running CI for the first time.
