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
- 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
- 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
- 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
- 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
