Description

Stacked buyer-visible TDD slice on live Draft #1406. The mail HWPX preview exposes an accessible Inkspan에서 편집 control for recognized attachments. The handoff preserves the exact opaque asset_key already authorized by the read-only preview lookup, never converts HWPX paragraphs into an editable Markdown/HTML document, never overwrites the original, and does not invent a write API.

The gap existed: #1406 could open recognized ordered paragraphs, but there was no explicit Inkspan editor handoff. Released Inkspan is still Markdown/HTML (v0.3.1 published; v0.6.0 unpublished and frozen under inkspan #118). Hangul import/edit/export remains unreleased inkspan Draft #320. Naruon has no installed Hangul document engine and no authorized document-copy/editor write contract, so this slice defines only the tested fail-closed capability/handoff boundary and stops before mutation.

Pending, failed, unavailable, and non-HWPX previews do not offer the edit control. A Markdown/HTML Inkspan adapter is rejected as silent conversion. Even a Hangul adapter without an authorized editor contract stays mutation_allowed=false and provider_write_executed=false. Malformed non-collection adapter family metadata fails closed as unavailable instead of raising. The UI shows Inkspan에서 편집 only when edit_handoff is present, the preview is recognized, and parser_family is hwpx.

This slice does not reconstruct tables/images/layout, convert binary HWP, call a model or NewsDOM, vendor inkspan #320, or change #1353/#1373/#1404/#1406 recognition/preview/mail-reachability semantics.

Fixes # (issue): continues #1406 buyer-visible mail HWPX preview; no new issue.

Review follow-up on this branch

Product conflicts

None beyond the earlier retarget resolution that kept both #1404/#1406 pending 다시 확인 and this fail-closed Inkspan handoff. Recognition/preview/mail reachability and mutation_allowed=false / provider_write_executed=false are unchanged.

Predecessor evidence does not transfer

Checks, reviews, OpenCode, Strix, CodeQL, Semgrep, Noema, Security Scan, CodeRabbit, Copilot, and any other gate results recorded against previous #1407 73208a952a2f79ccb25a7bd063a8dd4ddb69c9a3, 2b3792978c0221dff43d7b684ecf10635add5eeb, live #1406 b83a0da03b46a447f9710b5f91d245f5b1783dfa, stale #1406 304d5afa605c9121f23b9c68884d39ec3508f81e, #1404 f21811379c1cc2435eadb41bb2746b4887947d53, #1373 0fcf4d85dd70d4f2ee9dd0296fc454f764ae5326, #1353 70683266b93233dae62faec6cbd4df118be41383, or earlier stacked heads are stale for this current head. Only exact-current-head evidence counts.

Customer next action

Open the email that has the HWPX attachment. Select that file in 첨부 파일. Read the recognized ordered paragraphs. The Inkspan에서 편집 control is visible and disabled only for recognized HWPX: installed Inkspan cannot edit HWPX yet. Keep reading the recognized text or choose another file. If recognition is still pending, wait, choose another file, or use 다시 확인. Do not treat the disabled edit control as a successful edit, and do not treat a blank preview body as empty document content.

Actual HWPX editing requires a released/installed Inkspan Hangul document engine plus an authorized naruon editor/copy contract. Those are not present; inkspan Draft #320 remains frozen under inkspan #118.

  • New feature (non-breaking change which adds functionality)

📝 Walkthrough

Walkthrough

Recognized HWPX previews now carry a fail-closed Inkspan handoff. The backend preserves source identity and disables writes. The frontend displays a disabled edit control, localized fallback guidance, and readable recognized text.

Changes

HWPX Inkspan handoff

Layer / File(s) Summary
Fail-closed handoff service
AGENTS.md, backend/services/inkspan_edit_handoff.py, backend/tests/test_inkspan_edit_handoff.py, docs/doctoring/hwp-hwpx-attachment-recognition.md
The service accepts only released Hangul HWPX capability and authorized contracts. Recognized HWPX remains read-only, with no conversion, overwrite, provider write, or editable payload.
Preview and API propagation
backend/services/repository_asset_preview.py, backend/api/data.py, backend/tests/test_repository_asset_preview.py
Attachment and workspace-document previews include optional handoff data. API responses force mutation, conversion, overwrite, and provider-write flags to false.
Frontend handoff rendering
frontend/src/components/data-layout/*, frontend/src/components/MailAttachmentPreview.tsx, frontend/src/components/EmailDetail.test.tsx, frontend/src/components/MailAttachmentPreview.test.tsx, frontend/tests/e2e/*
The frontend renders a disabled Inkspan edit control with localized unavailable-capability guidance. Tests verify recognized text remains visible and internal asset identifiers are not exposed.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🔵 Low · up to b5115

The change adds an Inkspan edit affordance for HWPX previews, but the control may still appear for some previews that are not recognized HWPX, creating a misleading editing option for users. The PR is otherwise mergeable with explicit owner follow-up on that UI gating risk.

server error.

In `@docs/doctoring/hwp-hwpx-attachment-recognition.md`:
- Around line 239-241: Remove the leading issue-reference line from the
capability-probe paragraph and incorporate the references into the preceding
sentence using prose such as “PRs `#1353`, `#1373`, `#1404`, and `#1406`,” while
preserving the existing recognition and preview-contract meaning.

- Around line 53-73: Gate the edit handoff block in RepositoryAssetPreviewPanel
on edit_handoff being present, recognized being true, and preview?.parser_family
equaling "hwpx"; otherwise render nothing. Add tests covering pending HWPX
previews and recognized non-HWPX previews to verify the Inkspan control is
absent.

Please independently re-review exact current head b5115d433eb44b741674a5f3e85c466b8ebe3cd3. The three prior findings are now present in the branch: non-iterable Inkspan metadata fails closed with focused coverage, the doctoring capability-probe references are integrated into prose, and the RepositoryAssetPreviewPanel shows the handoff only for present, recognized HWPX previews. Keep this PR draft and validate current-head checks before any approval.

Current-head review request for PR #1407.

HEAD: b5115d4

The current draft includes fail-closed malformed Inkspan adapter metadata handling, hides the edit handoff for pending/non-HWPX previews, and covers those states in backend/frontend tests. The doctoring text records the stacked HWPX ownership boundary in customer-facing prose. Please review this exact draft HEAD with current Checks and provide structured findings; do not merge while it remains draft.

Exact current head b5115d433eb44b741674a5f3e85c466b8ebe3cd3: backend handoff and repository-preview tests 16 passed, 1 skipped. The current implementation treats non-collection accepted_source_families as absent and renders the Inkspan control only for recognized HWPX previews. Frontend hosted checks remain authoritative; no local frontend dependencies were installed.

PR #1407 exact current HEAD 22e4909dd13623190f61eae47baf74d70fa2b83a adds the remaining fail-closed UI boundary: the Inkspan handoff is rendered only when both the preview and handoff declare hwpx. A recognized HWPX preview carrying mismatched stale handoff metadata is covered by a regression test.

Focused verification on this HEAD: RepositoryAssetPreviewPanel Vitest 8 passed; ESLint, TypeScript, and git diff --check passed. Keep the PR Draft; please re-review this exact HEAD and rerun current-head Checks.
