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.
- Add ondelete=CASCADE/SET NULL to all environment and translate FK constraints
- Add is_multimodal to GET /api/settings/consolidated response
- Fix toggleActive to not overwrite is_multimodal with false
- New SearchableMultiSelect component for dashboard search with multi-select
- Fix validation task page: task data unwrapping, date formatting, dashboard multi-select
- Fix infinite effect loop on dashboards page via queueMicrotask guard
- 3 new Alembic migrations (merge f0e9d8c7b6a5, translate b0c1d2e3f4a5)
Backend:
- /api/validation/ CRUD for validation tasks (policies)
- Run history with 6 filters + pagination
- Alembic migrations (provider_id, policy_id)
- 28 pytest tests
Frontend:
- /validation — task list page with status filters + CRUD
- /validation/[id] — task config (Config + History tabs)
- /validation/history — run history with metrics
- Sidebar nav entry under Operations
- i18n en/ru
Playwright (ScreenshotService):
- Removed 25s hardcoded sleeps → conditional waits
- CDP fallback to full_page screenshot
- Total timeout enforcement (120s)
- Debug screenshots → temp dir with cleanup
QA fixes:
- Debug screenshot accumulation in production (tempdir + rmtree)
- Frontend API payload field name mismatch
- History issues field reference fix
- delete_runs scoped by policy_id
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
- Added Git section (Repository Status) - was hidden in routes
- Added Tools section (Mapper, Debug, Storage, Backups) - was hidden in routes
- Moved Settings gear icon to footer (quick link to /settings)
- Moved Profile to footer (avatar + username)
- Moved Collapse button to header (always visible)
- Organized Admin with all sub-items (Users, Roles, ADFS, LLM)
- Reduced visual noise: section labels collapse independently
- Kept existing features: RBAC filtering, health badges, mobile overlay, collapse animation
- 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
- 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)
- Show full stats grid (total/success/fail/skip) + progress bar + cancel button during active run
- Compact colored banner for terminal states (completed/partial/failed/cancelled) with auto-dismiss
- Import cancelRun from translate API for functional cancel button
- fromStore() reactivity confirmed working — no store changes needed
- Hide on /translate/[id] to avoid duplication (existing behavior preserved)
- Add _normalize_timestamp_value to key column values in orchestrator.py and executor.py before SQL generation
- Fix test mocks for .options(joinedload()) chain, explicit None attrs for mock job
- Add global translation run progress indicator (TranslationRunGlobalIndicator + store)
- Fix translate page import missing translationRunStore
- All 208 translate tests pass
- Enable response_format (json_object) for all providers including Kilo/OpenRouter
- Skip reasoning_effort for Kilo/OpenRouter (returns 400 — mandatory reasoning)
- Add structured_outputs fallback: retry once without response_format if upstream
provider (e.g. StepFun) rejects it with 'structured_outputs is not supported'
- Handle model refusal field (refusal) instead of treating as empty content
- Fix None-handling guards for message/finish_reason/content fields
- Apply same fixes to both preview.py and executor.py _call_openai_compatible
- Connect orphaned TermCorrectionPopup, BulkReplaceModal, BulkCorrectionSidebar
- Removed max-w-[200px] compression on source text column → now
gets proportional space
- Scrollable containers (max-h-32 overflow-y-auto) for long text cells
- Language columns: min-w-[200px]→[250px] with whitespace-pre-wrap
- Source language badge and status columns remain narrow (w-28, w-24)
Multi-language save fix:
- MultiSelect.svelte: selected prop changed to $bindable([])
(without $bindable, bind:selected never propagated to parent component,
so target_languages always stayed as default ['en'])
Target table column mapping (INSERT enhancement):
- target_language_column — stores language code (e.g. 'ru', 'en')
- target_source_column — stores original source text
- target_source_language_column — stores detected BCP-47 source language
- SQL generator includes these columns in INSERT when configured
- Frontend: 4 input fields under 'Target Column Mapping' section
with clear labels, placeholders, and i18n hints
Backend: model, schema, service, orchestrator
Frontend: job config page, i18n en+ru
DB: 3 new columns added to production
CR1: Add needs_review, language_overridden to translation_languages migration
CR2: Add per_language_metrics to translation_metric_snapshots migration
H1: BulkFindReplaceService.preview() now uses replacement_text (not find pattern)
H2: get_run_records now includes per-language data via selectinload
H3: Preview per-language approve/reject uses correct (jobId, rowId, lang) args
H4: _compute_config_hash now includes target_languages
- Auto-detection of source language per row via LLM (US6)
- Multi-target translation — one LLM call for N languages (US1-US3)
- Language-aware storage: TranslationLanguage, per-language stats
- Multilingual dictionaries with language-pair-aware filtering (US7)
- Inline correction on any run result + submit-to-dictionary (US8)
- Context-aware dictionary: auto-capture row context, usage notes,
Jaccard similarity, priority flagging in LLM prompts (US8b)
- Configurable preview sample size 1-100, cost warning at >30
- Per-language history & metrics with MetricSnapshot preservation
- 36 files, +5022/-373, all specs GRACE-Poly v2.6 compliant
Translations:
- FR-045: new-key-only execution mode — translate only rows with unseen keys
- Compare source row keys against TranslationRecord.source_data from last succeeded run
- Baseline expired (>90 days) fallback to full mode with baseline_expired event
- run_noop early return when zero new keys (skip LLM + SQL)
Scheduler reliability:
- Stale PENDING protection: runs older than 1h auto-marked FAILED, no longer block schedule
- load_schedules() reloads active translation schedules from DB on restart
- add_translation_job/remove_translation_job register/unregister with APScheduler
- execution_mode column on translation_schedules with additive DB migration
Automation view:
- GET /settings/automation/translation-schedules endpoint
- Translation schedules displayed on Automation page below validation policies
Trace propagation:
- seed_trace_id() in all background entry points:
TaskManager._run_task/_flusher_loop, SchedulerService._trigger_backup,
websocket_endpoint, IdMappingService, all standalone scripts
Migrations:
- dictionary_entries: origin_run_id, origin_row_key, origin_user_id
- translation_schedules: execution_mode
Tests:
- 3 new test modules (22 tests): core_scheduler, executor_filter, scheduler_execution+guard
- Fix pre-existing translate test isolation (conftest.py)
- Fix test_list_runs_filter_status parameter
- Add environment_id to TranslationJob model/schema/API + DB migration
- Pass environmentId from page to TranslationPreview and fetchPreview
- Fix _fetch_sample_rows: use result_type='samples' to include virtual cols
- Add 'kilo' and 'openrouter' to supported LLM provider types
- Make response_format conditional (skip for non-OpenAI upstream providers)
- Remove source_table field from form (redundant with datasource)
- Restore datasourceSearch display from saved job on page load
- Add request/response logging for LLM API calls
Move dataset review clarification into the assistant workspace and
rework the review page into a chat-centric layout with execution rails.
Add session-scoped assistant actions for mappings, semantic fields,
and SQL preview generation. Introduce optimistic locking for dataset
review mutations, propagate session versions through API responses,
and mask imported filter values before assistant exposure.
Refresh tests, i18n, and spec artifacts to match the new workflow.
BREAKING CHANGE: dataset review mutation endpoints now require the
X-Session-Version header, and clarification is no longer handled
through ClarificationDialog-based flows
Add readiness hints, blocker summaries, and progress cues across
the dataset review workspace to clarify partial recovery and
launch gating states.
Highlight read-only preview snapshots, pending semantic review,
clarification queue status, and unresolved validation blockers to
guide the next recommended action.
Document known limitations in backend test doubles so permission,
task dispatch, and uncovered persistence branches are explicit.
