Summary

Splits View.vue, which scoria flags as god-file (over 500 lines). Code is moved as it was; behaviour does not change.

New files under src/vue/:

• useMiniEditor.ts: the mini editor's state, opening, saving, closing and arrow-key moves. It takes the View's editableData, activeSheetIndex and persistSheets.
• useRenderedTable.ts: calculating the active sheet and rendering it as an HTML table (renderedHtml). It takes resolvedSheets, activeSheetIndex, customFunctions and locale. The engine instance also moves here, still one per View.
• editorSelection.ts: while the JSON editor is open, selects a clicked cell's JSON in the editor and scrolls it into view.
• excelDownload.ts: the .xlsx download.
• sheetRows.ts: normalizeSheetData, which reads the editor JSON's rows.

The file-backed load and save (fetchSheets, persistSheets, following the file, saves that were refused) stay in View.vue.

Items to Confirm

• The look and behaviour do not change. The old (origin/main) and new demos were driven in Chromium (playwright-core) through the same steps, and the results compared.
  • Steps, for each sample:
    • load it;
    • click several cells and move with the arrow keys;
    • save a string, then a formula with a format, in the mini editor, then close it;
    • with the JSON editor open, click cells;
    • download as Excel.
  • Compared: the View's DOM; the result data the demo shows (emit("updateResult")); the textarea's selection range and scroll position; the value and check state of each input; the downloaded file's name and the contents of its sheets.
  • All snapshots identical; no console errors.
• Computed styles were also compared across the states, as in chore: View.vue の style ブロックを Tailwind に置き換える #187. The only differences were two values caught mid-transition (0.2s): the ✕ button's background on hover and an input's border on focus.
• Beyond moving code: plainCellText and isEditableTarget captured nothing, so they move to module scope.
• Not exercised: the file-backed load and save need a host runtime the demo does not have. That code was not moved here.
• yarn lint, yarn typecheck, yarn build, yarn test and yarn test:engine pass. oxlint reports nothing.

CODEX VERDICT: LGTM

• No outstanding correctness, security, compatibility, consistency, i18n, or View-state-preservation concerns.
• Read PR head 899588bdf30c00d2fd19cd459767b7ca34083672; every hunk of git diff origin/main...HEAD was reviewed.
• Verification: yarn typecheck passed; yarn test:engine passed (2,216/2,216). npx vitest run --configLoader runner could not collect because the existing vite.config.ts evaluates __dirname as undefined under this runner; no PR file changes that config.

Axis	Result
correctness and edge cases	none
security (injection / path traversal / code evaluation)	none
tests: does a test go red if the new behaviour breaks	none; the supplied Chromium probe covers the main moved flows, while malformed/empty normalization, invalid JSON/error branches, and file-backed host flows are not exercised
API / schema / wire / on-disk compatibility	none
consistency with the rest of the codebase	none
i18n lockstep (src/lang has 8 locales)	none; no locale strings or locale files changed
TIER C: View behavior preservation with state moved into composables and setup ordering	none
move fidelity: openMiniEditor, closeMiniEditor, saveMiniEditor, handleKeyboardNavigation, calculateFormulas, renderedHtml, editor-selection branch, downloadExcel, normalizeSheetData	none; compared with origin/main:src/vue/View.vue, including the requested ref substitutions
setup order and hoisting	none; useMiniEditor is after activeSheetIndex, before reads of miniEditorOpen, and persistSheets is a function declaration
reactivity of values passed in	none; download reads sheets/title at click time and selection reads the current editable JSON at click time
supplied behavior/style verification	no moved entry point is missed by the exercised happy paths; the probe does miss the edge/error/file-backed branches listed above, and the computed-style probe does not test moved logic

FINDINGS COMPLETE: I read every hunk of the diff and this is every finding I have.
