Backend:
- TranslationRun model: add cache_hits Integer column (default 0)
- TranslationRunResponse schema: add cache_hits field
- _helpers.py/_run_list_routes.py/orchestrator_aggregator.py: include
cache_hits in all run API responses
- _batch_proc.py: count pre_rows served from translation cache per
batch, return cache_hits in batch result
- executor.py: accumulate cache_hits across batches, persist to run
- Alembic migration: dabc9709 — add cache_hits column to translation_runs
Frontend:
- translationRun.svelte.ts: add cacheHits to store state, WS handler,
polling handler
- TranslationRunProgress.svelte: 5-col stats grid with purple Cache card
- TranslationRunGlobalIndicator.svelte: 5-col stats with Cache
- TranslationRunResult.svelte: 5-col detail stats with Cache card
- History page: cache_hits shown in run list row + detail panel
Visual: cache hits shown in purple alongside green/yellow/red metrics
(total/success/failed/skipped). Visible during run + in history.
Tests: backend 69/69 translate tests ✅, frontend 698/698 tests ✅,
frontend build ✅
downloadSkippedCsv and downloadFailedCsv call api.fetchApiBlob()
but it was not exposed on the api object — causing
"o.fetchApiBlob is not a function" at runtime.
Delete deprecated code that has been fully replaced by v2:
- backend: validation.py routes, validation_run_service.py
- frontend: validation.js API module, validation/ pages
Add binary-search probe endpoint POST /providers/{id}/probe-max-images
that discovers the per-request image limit by sending incrementally
more 1x1 JPEGs via the provider's own API. Result is cached in the
new max_images column on the provider config.
- LLMProviderConfig: add max_images: int | None
- LLMProvider (SQLAlchemy): add max_images column
- Migration ed28d34edde7: clean ADD COLUMN
- LLMProviderService: create/update/set_max_images
- POST /providers/{id}/probe-max-images: binary search + error parsing
- ProviderConfig.svelte: 'Detect' button in edit modal + HelpTooltip
- i18n (en/ru): 11 new keys for probe UI
Fixes:
- Move batch size, upsert strategy, include source reference
from Config tab to Target Config tab (Write Settings section)
- Fix 'Dataset #26' fallback — look up real datasource name
via API when source_table is not saved in job data
- Persist include_source_reference in save payload and
restore from job data on load (was a pre-existing gap)
QA review fixes:
- Update @BRIEF contracts for both tabs
- Fix import indentation in +page.svelte
Other: help tooltips on translate pages, flow hint on list page,
git migration manager components, dashboard hub pages,
migration settings pages
1. Remove get_config_manager() call from translate_run_websocket
(@app.websocket /ws/translate/run/{run_id}) — was not imported
and unused. Also remove unused from sqlalchemy.orm import Session.
2. Fix prop name mismatch: showBulkReplace -> showPageBulkReplace
in RunTabContent. Use () for reactive two-way binding.
3. Add ('DRAFT') for status prop in RunTabContent.
Backend:
- Add /ws/translate/run/{run_id} WebSocket endpoint in app.py
- Streams structured run status every second (total_records,
successful_records, failed_records, progressPct, batch_count, etc.)
- Auto-detects terminal states (COMPLETED, FAILED, CANCELLED) and closes
- Authenticated via JWT/API key token query param
Frontend:
- Add getTranslateRunWsUrl() URL builder in api.js
- Update translationRunStore to use WebSocket instead of log stream
- WebSocket receives structured status JSON, updates store reactively
- Falls back to polling silently if WebSocket fails
- Keep polling as fallback for insert phase
Remove loadColumnsForDatasource, searchDatasources, selectDatasource,
toggleContextColumn, toggleSourceKeyCol, updateTargetKeyCol, isVirtual
from page — all moved to ConfigTabForm.svelte.
Add on datasourceId in ConfigTabForm to auto-load columns
when parent sets datasourceId (loadJob) or user selects a datasource.
Introduce a centralized tool registry system for the assistant to manage
executable operations, permissions, and tool catalogs. This refactors
the assistant dispatch logic from a monolithic approach to a modular,
decorator-based registry.
Key changes:
- Implement `AssistantToolRegistry` to handle tool registration,
permission checks, and safe operation identification.
- Add a suite of new assistant tools: backup, commit, branch creation,
deployment, health summary, environment listing, LLM operations,
maintenance, migration, and dashboard searching.
- Refactor `_dispatch.py` and `_llm_planner.py` to utilize the new
registry for intent resolution and tool catalog building.
- Enhance the LLM planner to support more descriptive clarification
responses in Russian when intents are ambiguous.
- Update the frontend to support the new tool-based workflow, including
improved i18n labels for assistant operations and a new step-by-step
wizard for the migration page.
- Add ADR-0008 to document the architectural decision for the tool
registry.
Introduce a new API key authentication mechanism to support service-to-service
communication (e.g., Airflow, CI/CD) without browser-based JWT login.
- Add `APIKey` model and `APIKeyPrincipal` dependency for RBAC.
- Implement `require_api_key_or_jwt` dependency with environment scoping.
- Add admin CRUD endpoints for API key lifecycle management.
- Add API key management UI in System Settings.
- Update maintenance API to support explicit `environment_id` and API key auth.
- Add i18n support for API keys and connection settings.
- Include Python and Bash usage examples in the `examples/` directory.
- Update technical specifications and documentation.
Как на maintenance с шаблоном баннера — добавил чипсы-шаблоны
SQL-запросов над textarea в модалке маппинга колонок:
- information_schema — вставляет запрос к information_schema
с JOIN pg_description для получения описаний колонок
- Custom table — вставляет запрос к кастомной таблице маппинга
- Clear — очищает поле
Чипсы в стиле rounded-full с hover-эффектами, подпись
"Шаблоны:" и title-tooltip на каждой кнопке.
i18n: 6 новых ключей (sql_templates, sql_template_*).
StatsBar — title-подсказки на все кнопки-фильтры.
DatasetList — action-кнопки заменены на SVG-иконки с tooltip
(title="map_columns_tip" / "generate_docs_tip"), title на
select/deselect и пагинацию.
+page.svelte — title на refresh, bulk-панель, обе модалки
(маппинг колонок и генерация docs): source_type_tip,
database_tip, sql_query_tip, file_input_tip, llm_provider_tip
и текстовые хинты. Добавлены id на form-элементы для a11y.
i18n: 20 новых tooltip-ключей в ru/en.

Belief protocol:
- @RATIONALE/@REJECTED on 27 C4+ contracts
Closes: VALIDATION-REWORK-2026
- Split sidebar into 3 groups: Resources / Operations / System
- Added Migration section (Overview + Mappings) - was hidden in routes

- Updated tests to match new structure
- Updated i18n (en/ru) with new keys
- TranslationRunGlobalIndicator: replace fromStore + 6x with
(() => store.subscribe()) to prevent accumulating render_effect
instances via createSubscriber that caused infinite Svelte reactive flush
- translate/[id]/+page.svelte: add runComplete flag to hide progress bar
after completion without touching the store; add collapsible run detail
cards with status badge, counts, and error_message; filter invalid runs
- translationRun.js: remove stale guard (no longer needed)
- Sidebar.svelte: fix mobile overlay close on route change
- docs/adr/ADR-0007-rejected-fromStore-derived.md: document REJECTED pattern
- frontend: add to reload job data on param change after goto
- frontend: set existingJob from createJob response for immediate tabs
- frontend: suppress error toasts for schedule 404 (normal state)
- frontend: conditional ScheduleConfig mount to avoid 'new' job loading
- backend: skip preview check for jobs with direct Superset datasource
- backend: add orthogonal test for datasource+no-preview success case
- Extract _fallback_cancel_request for row lock timeout recovery in orchestrator_cancel
- Add flush lock timeout fallback in cancel_run
- Set error_message when all records fail in executor
- Track insert_failed state in scheduler and frontend store
- Migrate TranslationRunProgress from local polling to centralized store
- Fix nginx resolver for Docker variable-based proxy_pass
- Add FRONTEND_HOST_PORT env var to docker-compose
- Sidebar.svelte: defer healthStore.refresh() until feature flags confirm
health_monitor is enabled; skip entirely when disabled
- health.js: remove throw error from catch block — log and return null
instead, preventing 'Uncaught (in promise)' on expected 404
- test_report_audit_immutability.py: fix mock assertions —
audit_service uses logger.reason/reflect/explore, not logger.info
- HealthStore and Sidebar now produce zero network noise when
FEATURES__HEALTH_MONITOR=false
- Add source_hash column (SHA256 of source_text+source_data+dict_hash+config_hash) to TranslationRecord for cache dedup
- Add Alembic migration b1c2d3e4f5a6 for the new column and composite index (source_hash, status)
- Implement _compute_source_hash / _check_translation_cache in executor.py — before LLM call, check if same source+dict+config combo was already translated successfully
- Implement cache-aware routing in _process_batch: full cache hit → skip LLM, partial hit → route to LLM
- Store source_hash on all new TranslationRecord rows for future cache hits
- Strengthen dictionary prompt instructions from 'use when applicable' to 'MUST use — mandatory'
- Add _enforce_dictionary() post-processing: force-replace dictionary terms in LLM output if LLM ignored them
- Fix CRITICAL: use run.dict_snapshot_hash/config_hash (exist on TranslationRun, not TranslationJob)
- Fix MAJOR: verify cached languages cover ALL target_languages before accepting cache hit
- Fix MAJOR: prevent regex back-reference injection in dictionary enforcement (use lambda)
- Fix: add joinedload to cache lookup to avoid N+1 queries
- Fix: remove redundant single-column index (composite index is sufficient)
- Fix(frontend): parse paginated /translate/dictionaries response correctly (result.items)
