3. **Transfer Assistant wizard deleted.** "Setup & Transfer" pane renamed to "Setup". Replacement: Extension ID display + Copy button added to Diagnostics → Native host registration fieldset (always visible, not failure-gated). Sidebar entry, fieldset, modal, and ~107 lines of JS removed.
5. **Recent Activity + Search Troubleshooting moved to new Debug Tools pane.** Verified Recent Activity is search-trigger-only by reading `background.js` — `recordActivity()` is NOT called from `delete-file` handler. No audit-value split needed. New sidebar entry "Debug Tools" under System group; new `pane-debug` houses both fieldsets.
6. **options.js split — Cache & Scans + Duplicate Review paired extraction.** `options.js` 3133 → 2356 lines. New files: `options-cache.js` (161 lines, Cache & Scans block), `options-dupe-review.js` (616 lines, Dup Review + Keep Ranking incl. bottom `loadKeepRanking()` call). Script-tag order in `options.html`: cache → dupe-review → options.js (body bottom). Cross-script binding visibility (vanilla classic scripts share global declarative env): Library Issues code still in options.js reads `_configuredScanRoots` / `_cacheSkippedByRemote` / calls `rememberConfiguredScanRoots` from cache file by bare reference. Calls to `escapeHtml` / `openModal` / `closeModal` / `keepActionViewport` / `clearNativeRepairCard` / `renderNativeMessagingFailure` from extracted files all occur inside event handlers (resolved at call time, after options.js parses). Repo `git init`'d before this step; baseline commit `f8e781f` is the rollback point. Verified by `node --check` on each file and on concatenated script.
+6b. **options.js split — Library Issues extraction.** `options.js` 2356 → 1903 lines. New file: `options-library-issues.js` (453 lines) — covers `lastLibraryIssues`, `_libraryIssuesDirty`, `renderLibraryIssues`, `_closeLibraryIssues`, and the bottom IIFE that wraps `_optScanTimer` / `_setOptScanningState` / `_pollOptProgress` for optimization-scan progress polling. Block was fully self-contained (no external callers of its identifiers). Reads `_configuredScanRoots` / `_cacheSkippedByRemote` / calls `rememberConfiguredScanRoots` from `options-cache.js` — same cross-file binding pattern proven in step 6. Script-tag order in `options.html`: cache → dupe-review → library-issues → options.js. `node --check` passes on each file and on concatenation; line count of concat (3133) matches pre-split total exactly.
(Step 4 in the plan is a paired-extraction sub-task of step 6; folded into step 6 ship.)
**Pending (in execution order):**
-- **Step 6b — continue options.js split with Library Issues, Debug Tools handlers, Settings sub-tabs.** Library Issues is the next obvious ~450-line block (lines 1505–1957 in pre-split numbering, now in options.js mid-section). Reads `_configuredScanRoots` and `_cacheSkippedByRemote` from `options-cache.js` — cross-file binding already exercised, so the extraction is lower risk than the first pair.
+- **Step 6c — finish options.js split (optional).** Remaining options.js (1903 lines) still holds: settings load/save, backup/restore, recent activity, search test bench, bulk ID check, adapters, ID normalizers, part detectors, element picker, overlay previews, diagnostics, profiles, paths, and the bottom-entry IIFE. Candidates for extraction: Diagnostics (~250 lines, 1354–1603 in current options.js), Profiles (~265 lines), Adapters + ID normalizers + Part detectors as a "rules editors" file (~330 lines combined). Diminishing returns past this point — bottom IIFE + load/save core should stay in `options.js` as the entry point.
- **Step 7a — Bulk Check standalone window.** New `bulk-check.html` opened as detached `chrome.windows.create({ type: 'popup', width: 640, height: 540 })` from a "Bulk Check" launcher button in the popup. Single canonical entry path — NOT a Console sidebar tab. Window dedup via `chrome.storage.session`, last-paste persisted via `chrome.storage.local`.
- **Step 8 — Shared fixture corpus.** Top-level `D:\DEV\Project\rclone-jav\fixtures\` (neutral location, NOT inside Python or extension repo). JSON cases for query-ID extraction (extension), filename ID extraction (Python), shared normalization.
- **Step 9 — Cache contract design.** CACHE_VERSION already exists (currently 3). Add ID_RULES_VERSION concept: schema bump = force rebuild, rules bump = warn-and-mark-stale.
