+# Issue #425 — hands-on delivery
+
+## Task
+
+Verify and ship clipboard image paste + drag-and-drop for KiwiEditor ([#425](https://github.com/kiwifs/kiwifs/issues/425)) after fleet agent delivery check failed (no push, no PR).
+
+## Actions
+
+1. Verified existing implementation on `feat/issue-425-image-paste-redelivery` (2 commits ahead of `origin/main`).
+2. Fixed double `renameFileForPaste` in CodeMirror upload path — `uploadAssetForEditor` already renames; alt text now derived from uploaded asset ref basename.
+3. Ran full UI test suite — 200 passed (11 image-paste tests).
+4. Pushed branch and opened PR closing #425.
+
+## Tests
+
+```bash
+cd ui && npm test -- --run editorImagePaste   # 11 passed
+cd ui && npm test -- --run                    # 200 passed (35 files)
+```

+# Issue #425 — verified delivery (hands-on takeover)
+
+## Task
+
+Re-verify and ship clipboard image paste + drag-and-drop for KiwiEditor after fleet delivery check failed (`no_committed_diff`, `peer_review_not_passed`).
+
+## Actions
+
+1. Confirmed implementation on `feat/issue-425-image-paste-redelivery` (3 commits ahead of `origin/main`).
+2. Peer review: aligned `imagePasteProsemirrorPlugin` with CodeMirror path — upload callback owns rename; alt text from asset ref basename; full `/raw/` URL for ProseMirror `src`.
+3. Removed "Made with Cursor" from fork PR #61 body.
+4. Ran full UI suite — 200 passed (11 image-paste tests).
+
+## Tests
+
+```bash
+cd ui && npm test -- --run editorImagePaste   # 11 passed
+cd ui && npm test -- --run                    # 200 passed (35 files)

+
+## Context
+
+Hands-on takeover after fleet agent delivery check failed (no PR, peer review not passed). Branch `feat/issue-425-image-paste-redelivery` already had core image paste implementation.
+
+## Peer review fixes
+
+1. **Autosave placeholder leak** — Block source-mode save while `pendingImageUploads > 0` or doc contains `kiwi-upload://` placeholders via `isUploadingPlaceholder()`.
+2. **Safari clipboard extraction** — `extractImagesFromDataTransfer` falls back to `dataTransfer.files` when items have empty MIME types.
+3. **Paste/drop handler tests** — Exported `editorImagePasteDomHandlers`; added tests for `beginImageInsert`, paste, and drop paths.
+4. **Dead code** — Removed unused `imagePasteProsemirrorPlugin.ts` (BlockNote `uploadFile` handles visual mode).
+5. **Drop overlay helper** — `shouldShowEditorImageDropOverlay` now requires pasteable image in transfer.
+
+## Tests
+
+```bash
+cd ui && npm test -- --run
+# 204 passed (35 files)
+```
+
+## Outcome
+
+Committed fixes, pushed branch, opened PR closing #425.

+
+# Issue #425 — image paste from clipboard
+
+## Task
+
+Implement clipboard image paste and drag-and-drop in KiwiEditor (visual BlockNote + source CodeMirror) per [kiwifs/kiwifs#425](https://github.com/kiwifs/kiwifs/issues/425).
+
+## Approach
+
+- Shared helpers in `editorImagePaste.ts` (MIME detection, `paste-YYYYMMDD-HHMMSS.ext` naming, relative markdown refs).
+- Source mode: CodeMirror `editorImagePasteExtension` inserts `![Uploading...]()` placeholder, uploads via `api.uploadAsset`, replaces with `![name](relative-path)`.
+- Visual mode: BlockNote native `uploadFile` path with `renameFileForPaste`, block removal + toast on failure.
+- Drop-zone overlay on editor area for both modes.
+- Error toast bottom-left (mirrors slash-command alert pattern).
+
+## Tests
+
+```bash
+cd ui && npm test -- src/lib/editorImagePaste.test.ts src/lib/editorImagePasteExtension.test.ts
+# 11 passed
+
+cd ui && npm test
+# 217 passed
+```
+
+## Branch
+
+`feat/issue-425-image-paste` (local commit only; fleet publishes PR).

+# Issue #425 — image paste redelivery
+
+## Task
+
+Re-deliver clipboard image paste and drag-and-drop for KiwiEditor per [kiwifs/kiwifs#425](https://github.com/kiwifs/kiwifs/issues/425).
+
+## Approach
+
+Cherry-picked `b3cdd95` onto `origin/main` as branch `feat/issue-425-image-paste-redelivery`. Removed Cursor co-author attribution from commit message.
+
+Implementation unchanged from prior delivery:
+
+- Shared helpers in `editorImagePaste.ts`
+- Source mode: CodeMirror `editorImagePasteExtension` with upload placeholder
+- Visual mode: BlockNote `uploadFile` wrapper with rename + error toast
+- Drop-zone overlay via `EditorImageDropOverlay.tsx`
+
+## Tests
+
+```bash
+cd ui && npm test -- --run editorImagePaste
+# 11 passed
+
+cd ui && npm test -- --run
+# 200 passed (35 files)
