- 19 tests covering:
- disableReasoning load from API (true, false, omitted, null)
- disableReasoning save to API (POST new + PUT update)
- databaseDialect save to API (populated, empty, PUT)
- datasourceSearch name lookup on job page load
(found by ID, found by string ID, not found, no ID, API error)
- uxState transitions: loading→configured, idle on job fetch
failure, idle on Promise.all entry failure
Also changed datasourceSearch lookup from fire-and-forget .then()
to awaited try/catch — guarantees name is populated before
uxState transitions to 'configured'.
When opening a saved translation job, the datasource search input was empty
because datasourceSearch was never populated from the loaded job data.
The raw datasourceId was loaded correctly, but the display name
("table_name (database · dialect)") was missing.
Added fetchDatasources lookup in loadInitialData after environmentId is set:
finds the matching datasource by ID in the list and sets datasourceSearch
to the same format used in selectDatasource().
- HIGH: disableReasoning was declared as and bound in UI but never
loaded from API (loadInitialData) nor sent in save payload. Checkbox was
decorative — value always defaulted to false and never persisted.
Backend fully supports disable_reasoning column + schema + runtime logic.
- MEDIUM: databaseDialect was loaded from API and displayed in UI but never
returned in save payload, causing unnecessary back-end re-detection on
every save.
- Documents includeSourceReference as known limitation (no backend column).
Three fields were never loaded from backend job data:
- targetLanguageColumn (job.target_language_column)
- targetSourceColumn (job.target_source_column)
- targetSourceLanguageColumn (job.target_source_language_column)
Caused empty inputs in Target Config tab after page load.
Also added missing target_source_language_column to save payload.
@RATIONALE The model's loadJob() method was incomplete — it only
loaded targetColumn but omitted the other three target mapping fields.
Save payload also omitted target_source_language_column.
Verification: browser reconfirmed — all 4 target columns pre-filled
with saved values after reload.
Following the documented pattern from 27435e4 (bug report:
docs/bug-reports/2026-06-02-svelte5-proxy-store-t-undefined.md).
$t.x references in .svelte.ts files are fragile — Svelte 5 compiler
can fail to detect the Proxy-based t store as subscribable, causing
ReferenceError: $t is not defined at runtime.
Changed 3 model files:
- DashboardDetailModel.svelte.ts — 8 $t.dashboard?.x → getT()?.dashboard?.x
- TranslateHistoryModel.svelte.ts — 4 $t.translate?.run?.x → getT()?.translate?.run?.x
- ValidationTasksListModel.svelte.ts — 2 $t.validation?.x → getT()?.validation?.x
All imports changed from { t } to { getT } (or { _, getT } for
TranslateHistoryModel which already used _() for keyed lookups).
@RATIONALE getT() returns the plain translation object directly,
bypassing the Proxy store entirely — this avoids Svelte 5's fragile
static store-detection on Proxy objects.
Verification: npm run build clean, browser renders for all 4 affected
routes with zero console errors.
Svelte 5 compiler fails to detect Proxy-based i18n store `t` as a store
in deeply nested/complex templates and in `.svelte.ts` model files,
generating `ReferenceError: $t is not defined` at runtime.
Fix: replace `$t.` references with:
- Template: `_t.` where `const _t = $derived(getT())`
- Script: `getT()?.` direct function call
Applied to:
- translate/[id]/+page.svelte (the failing page)
- TranslationJobModel.svelte.ts ($derived.by() in `tabs`)
- 12 translate components (ConfigTabForm, ScheduleConfig,
TranslationPreview, TargetTabForm, RunTabContent, BulkReplaceModal,
TranslationRunProgress, TranslationRunResult, TermCorrectionPopup,
BulkCorrectionSidebar, TranslationMetricsDashboard, CorrectionCell,
TranslationRunGlobalIndicator)
Verified all 5 tabs render correctly in browser:
Config, Preview, Target, Run, Schedule.
Build clean, 698/698 tests pass, 0 color violations.
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
