+# Task 11 report
+
+## Mapping
+
+- Source common, Case, Reference, and Question fields → exact target labels, controls, order, loaded values, conditional resolution fields, and CSS classes.
+- Source ordered text/rule/option/relation editors → presentation-owned add, remove, reorder, local IDs, limits, and accessibility names.
+- Source document editor/status rail → source tabs, keyboard focus, working-copy status, dirty indicator, version/kind rail, and deferred workflow controls.
+- Source instant preview → Content Format v1 `projectWorkingCopy` plus the shared `PublicRecordRenderer`; no gateway preview mutation or parser/renderer duplication.
+- Source edit page → registered route input adaptation for the document ID.
+- Task 10 provider seam → smallest generic provider-owned editor session (`saved`, `draft`, `status`) retained across editor tabs.
+
+## TDD evidence
+
+- RED: `corepack pnpm exec vitest run tests/features/tech-log/studio-editor-smoke.test.tsx` failed at the exact missing `document-editor-screen.tsx` import before test collection.
+- First GREEN: the same focused command passed 1 file / 5 tests.
+- Focused regression: editor smoke plus `content-format.test.ts` and `public-render.test.tsx` passed 3 files / 41 tests.
+- Scope check: `git diff --check` passed.
+
+## Files
+
+- Added the 12 Task 11 component/page files under `src/features/tech-log/presentation/studio/`.
+- Extended `studio-provider.tsx` and `use-studio.ts` only with presentation-owned editor session state.
+- Added `tests/features/tech-log/studio-editor-smoke.test.tsx`.
+
+## SHA
+
+- Base: `887f5e6eb1a5ccdf4feab0b27fae1c5823233190`.
+- Implementation: the commit containing this report, titled `feat: port TechLog Studio editors` (final SHA recorded in the Task 11 handoff).
+
+## Deferred
+
+- Save/conflict resolution, guarded navigation, validation, server preview, publish, and unpublish workflows remain deferred to Tasks 12/13. The source Save control is present but disabled until Task 12 supplies the workflow.
+- Broad app/test types, lint, build, architecture, security, visual, and full-suite gates remain deferred to integrated Task 14 by user direction.
