executor.execute_run() is async def but was called without await in
TranslationExecutionEngine.execute_run(). This returned a coroutine
instead of a TranslationRun, causing:
'coroutine' object has no attribute 'status'
This made every translation run fail in the background execute path.
run_translation was def (sync FastAPI handler runs in thread pool with no event
loop), but its body calls asyncio.create_task(_background_execute()) which
requires a running event loop. Changed to async def so FastAPI runs it on the
event loop directly.
Error: 'Run failed: no running event loop'
get_dashboards_page_async() no longer exists — the sync/async split was
removed and the method is now simply get_dashboards_page() (already async).
Calls in dashboard slug resolution and git helpers were using the old name.
This caused AttributeError at runtime, making all slug-based dashboard
lookups fail with 'Dashboard not found'.
SupersetClientBase was missing aclose() method. AsyncSupersetClient had it
via override, but code creating SupersetClient directly (e.g. dashboard tasks
history route) would fail with AttributeError on await client.aclose().
All test methods calling validate_target_table_schema now async def + await.
Mocked async methods (resolve_database_id, execute_and_poll) use AsyncMock
instead of MagicMock since await on MagicMock raises TypeError.
_prime_dashboard_meta_cache was sync but called async get_dashboards_summary().
Parent get_health_summary was already async def. Made child async + added awaits.
db_name and backend were initialized inside the try block but referenced
in the except handler. If an exception occurred before their assignment
(e.g. in resolve_database_id), the except block would raise:
cannot access local variable 'db_name' where it is not associated
Moved initialization before try with safe defaults.
Three sync functions called async SupersetClient methods without await:
- get_datasource_columns(): get_dataset_detail + get_database (async)
- fetch_available_datasources(): get_datasets (async)
- Route handlers: both calls missing await
Converted to async functions + added awaits. Both endpoints now return
proper data instead of coroutine errors.
Svelte 5 does not allow duplicate class: directives on the same element.
The two class:border-warning (and two class:bg-warning-light) conditions
were mutually exclusive but Svelte rejected them at compile time.
Merged into single || condition.
git_service.get_status() is async def, but was called without await,
returning a coroutine object instead of dict. The coroutine was then
used as a dict value in RepoStatusBatchResponse, causing Pydantic
ValidationError (dict type mismatch).
get_dataset_linked_dashboard_count is async (coroutine function), but was
passed to asyncio.to_thread() which expects a sync callable. This returned
a coroutine object instead of an int, causing:
'>' not supported between instances of 'coroutine' and 'int'
Fix: await the async method directly inside asyncio.wait_for().
Found 3 missing 'await' keywords causing 'coroutine object is not iterable':
- get_dashboards_summary() (line 57)
- get_dashboards_summary_page() (line 114)
- get_datasets_summary() (line 306)
All three were calling async methods in sync context — returned coroutine
objects instead of lists/dicts, causing iteration failures.
HIGH: 'bodyClass' and display logic updated — 503/504 errors now show
warning (yellow) styling and 'Could not verify' message instead of
destructive (red) 'Table not found'. Backend now returns 503 on pool
exhaustion and 504 on upstream timeout after async refactoring.
All routes (assistant, migration, datasets, git) now use AsyncSupersetClient.
_helpers.py sync->async for dashboard ref resolution.
_detail_routes.py import fixed.
Known residual: MigrationDryRunService and IdMappingService still sync.
Add L1 invariant tests for all Screen Models:
- DashboardDetailModel: test load, delete, pagination, column filter
- DashboardHubModel: test load, environment switching, selection, git actions
- DatasetDetailModel: test load, edit, delete
- DatasetsHubModel: test load, filter, pagination

BackupManager:
- Add AbortSignal.timeout(30s) to prevent infinite loading state
- Add onDestroy AbortController cleanup to prevent stale state
- Add error toasts for failure states (was missing — state hung forever)
- Import API_REQUEST_TIMEOUT from api.ts
Extract state management from inline health page into HealthCenterModel:
- HealthCenterModel.svelte.ts (new): hosts all state atoms (),
derived values (), and core actions (load, filter, delete)
- health page reduced from ~120 to ~27 lines of script — thin shell
delegating to model; only DOM/template concerns remain
- Integration test updated for model-based architecture
- HealthCenterModel.test.ts (new): model invariant tests
Extract all state management from the inline page into a dedicated
DatasetReviewModel class following the Screen Model pattern:
- DatasetReviewModel.svelte.ts (new): hosts all state atoms (),
derived values (), and core actions (load, submit, export)
- review-workspace-helpers.ts moved from routes/ to /helpers/
- useReviewSession.ts moved from routes/ to /api/dataset-review/
- DatasetReviewModel.test.ts (new): model invariant tests
- [id]/+page.svelte: reduced from ~380 to ~190 lines — thin shell
delegating to model; only navigation/DOM concerns remain inline
- Old files deleted: routes/datasets/review/{review-workspace-helpers,useReviewSession}.ts
- Updated ux test for new model-based architecture
- Add FetchOptions.signal for request cancellation (timeout or unmount)
- Propagate signal to native fetch() in fetchApi, fetchApiBlob, postApi,
requestApi, patchApi, putApi, and deleteApi
- Export API_REQUEST_TIMEOUT constant (30s default)
- Add @INVARIANT for signal propagation contract

- Fix test_session_repository assertion after store refactor
Add support for regex-based dictionary entries across the full stack:
Backend:
- DictionaryEntry model: add is_regex column (Boolean, default False)
- DictionaryEntryCRUD: validate regex on add_entry(), compile on creation
- _enforce_dictionary: match by regex pattern when is_regex=True
- dictionary_filter: support is_regex in filter/query
- metrics: include is_regex entries in metrics calculations
- Alembic migration: 20260604_add_is_regex_to_dictionary_entries
- Merge migration: 351afb8f961a (merge is_regex + composite index heads)
Frontend:
- DictionaryDetailModel: add is_regex field to DictionaryEntry interface,
EditForm, and addForm; sync edit/add form state with backend schema
Extract inline edit, bulk find-replace, and override language endpoints from
_run_routes.py into dedicated _run_edit_routes.py and _run_history_routes.py
modules to reduce module complexity below INV_7 limits.
Changes:
- _run_routes.py now only handles execution, retry, and cancel endpoints
- _run_edit_routes.py (new): inline edit, bulk find-replace, override language
- __init__.py registers the new route modules
- schemas/translate.py: add imports for extracted endpoints
BaseHTTPMiddleware (Starlette 0.50.0) uses anyio.create_task_group() internally,
creating separate asyncio tasks for dispatch vs call_next. ContextVars set in
dispatch() were not visible to outer middleware like log_requests.
Converting to raw ASGI middleware ensures trace_id is seeded in the root task
context, visible to ALL middleware layers.
Key changes:
- Replace BaseHTTPMiddleware with raw ASGI __call__(self, scope, receive, send)
- UUID v4 validation: check parsed.version == 4 explicitly instead of relying
on uuid.UUID(hex=..., version=4) which silently mutates non-v4 UUIDs
- Add @RATIONALE and @REJECTED tags per semantics-core protocol
- Update app.py comment to document the architectural decision
- Add composite index ix_translation_records_run_source_hash
for NOT EXISTS dedup subquery performance + Alembic migration
- Remove duplicate #endregion in orchestrator.py (INV_3)
- Replace hardcoded RU fallback 'Статус' with 'Status'
- Add early return guard to loadMoreRecords()
- Show records summary always when recordsTotal > 0
Backend:
- deduplicate param in GET /runs/{id}/records — NOT EXISTS subquery
with (created_at, id) tiebreaker for one row per source_hash
- source_data and source_hash added to records JSON response
- fix missing status import in _run_history_routes.py (NameError)
- fix tab/space mixup in orchestrator_aggregator.py
- remove duplicated @RELATION edges in metrics.py
- fix #region/#endregion style and @PURPOSE→@BRIEF in metrics.py
Frontend:
- RunTabContent: summary metrics bar (fetchJobMetrics) with HelpTooltips
- RunTabContent: trigger_type badge, duration, cache rate in run rows
- TranslationRunResult: deduplicate=true by default, paginated Load more
- TranslationRunResult: per-language token_count and estimated_cost
- TranslationRunResult: collapsible batch breakdown with timing
- TranslationRunResult: Bulk Replace button in header and records table
- TranslationRunResult: source_data key values shown under source text
i18n: all new keys in EN + RU (load_more_records, showing_records,
sum_*, help_sum_*, trigger_*, batch_*, duration_label, cost_label,
cache_rate, load_more_records)
