 Changes:
-Create PR_26130_004-workspace-return-tool-enable-regression.
+Create PR_26130_006-preview-generator-handle-write-verification.
 Read docs/dev/PROJECT_INSTRUCTIONS.md first.
-Fix Workspace Manager V2 regression where returning from any tool leaves all workspace tools disabled/gray.
-On return from a tool, preserve the selected repo, selected game, live repo folder handle, active game binding, and enabled tool list.
-Do not treat normal return navigation as Cancel, Close, or lost file handle.
-Only disable tools when no valid opened game/toolState is active or when repo binding is actually missing.
-Add explicit log lines for return-from-tool state restoration: repo selected, game selected, source binding status, enabled tool count.
-Keep Save disabled only when no live writable file handle exists.
-Keep scope limited to Workspace Manager V2 return state and tool enablement regression.
+Fix Preview Generator V2 write verification so SVG writes are verified through the same live repo FileSystemDirectoryHandle provided by Workspace Manager V2.
+Do not treat absolute path string comparison against handle-relative path as a mismatch.
+Normalize path reporting into:
+- repo display label
+- repo root path string
+- handle root name
+- handle-relative output path
+- absolute display path
+After SVG write, verify by re-reading the handle target and logging:
+- file exists
+- file size
+- modified timestamp when available
+- content starts as SVG
+- output path
+- handle-relative path
+If Preview Generator cannot write through the Workspace Manager live repo handle, fail visibly and do not claim OK WRITE.
+Document whether the handle is passed from Workspace Manager or resolved from workspace.repo.reference/session runtime state.
+Keep scope limited to Preview Generator V2 handle/path/write verification.
 No unrelated files.
 No start_of_day changes.
 
 Validation:
 Run npm run test:workspace-v2.
-Add/update Playwright test for opening a game, launching a tool, returning to workspace, and verifying tools remain enabled.
-Add/update Playwright test that Save state remains correct after return.
+Add/update Playwright coverage for Preview Generator V2 using Workspace Manager repo handle, SVG write verification, and no false OK WRITE when handle write/read verification fails.
 Do not run full samples smoke test; document skipped reason.

 ## Playwright Impact
 
 Playwright impacted: Yes.
 
-Workspace Manager V2 Playwright now validates opening a game, launching workspace tools, returning to Workspace Manager V2, keeping workspace tools enabled, preserving repo/game/source binding, and preserving clean/dirty Save and Close button state after return.
+Workspace Manager V2 Playwright now validates Preview Generator V2 restoring the live Workspace Manager repo handle, writing `preview.svg` through that handle, logging read-back verification details, and failing without `OK WRITE` when handle read-back verification fails.
 
-Expected pass behavior: normal Return to Workspace restores the active repo, game, source binding, enabled tool count, and refreshed dirty toolState data without requiring Pick Repo Folder.
+Expected pass behavior: Preview Generator V2 writes and verifies `preview.svg` through the live repo handle, reports handle-relative and absolute display paths separately, and logs file exists/size/modified/SVG-start metadata.
 
-Expected fail behavior: tests fail if return navigation drops the live repo handle, grays out tools, enables Save without a live binding, disables Save while dirty after a valid return, or omits the return-state log lines.
+Expected fail behavior: tests fail if Preview Generator V2 falls back to session-only writes, logs a false path mismatch for absolute-vs-handle-relative paths, claims `OK WRITE` after read-back verification fails, or cannot restore the Workspace Manager V2 live repo handle.

+# PR_26130_006-preview-generator-handle-write-verification
+
+## Summary
+
+- Preview Generator V2 workspace launch now restores the live Workspace Manager V2 repo `FileSystemDirectoryHandle` instead of creating a session-backed synthetic repo writer.
+- `preview.svg` writes are verified by re-reading the live handle target before `OK WRITE` is logged.
+- Write logs now separate repo display label, repo root path string, handle root name, handle-relative output path, and absolute display path.
+- SVG write verification logs file existence, file size, modified timestamp when available, SVG-start detection, output path, and handle-relative path.
+- Absolute display paths are no longer compared directly against handle-relative paths, removing the false path mismatch warning.
+
+## Scope
+
+Changed only Preview Generator V2 live repo handle restoration/path/write verification and Workspace Manager V2 Playwright coverage for that behavior.
+
+No `start_of_day` files were modified.
+
+## Handle Source
+
+The live handle is resolved from Workspace Manager V2 runtime state, not passed through or serialized inside toolState JSON.
+
+Preview Generator V2 reads `workspace.repo.reference`, then restores the matching live repo handle from the Workspace Manager V2 repo handle cache:
+
+- Test/runtime hook: `window.__workspaceManagerV2RepoHandleCache.restore({ reference })`
+- Browser fallback: IndexedDB cache `workspace-manager-v2-repo-handles` / `repo-handles` / `active-repo-handle`
+
+`manifest.repoPath` is used for repo root path string and absolute display path reporting. It is not used as the write authority and is not compared as if it were handle-relative.
+
+If no live Workspace Manager V2 repo handle can be restored, Preview Generator V2 logs the exact restore failure and required recovery action, leaves generation disabled, and does not claim `OK WRITE`.
+
+## Validation
+
+- `node --check tools/preview-generator-v2/PreviewGeneratorV2RepoAccess.js`
+- `node --check tools/preview-generator-v2/PreviewGeneratorV2App.js`
+- `node --check tests/playwright/tools/WorkspaceManagerV2.spec.mjs`
+- `npm run test:workspace-v2`: 23 passed
+- `git diff --check`: passed
+
+Full samples smoke test was skipped because this PR is limited to Preview Generator V2 handle/path/write verification and does not modify shared sample loading, sample manifests, or broad sample runtime behavior.
+
+## Playwright Coverage
+
+Playwright impacted: Yes.
+
+Validated behavior:
+
+- Preview Generator V2 restores the Workspace Manager V2 live repo handle through `workspace.repo.reference` plus the runtime handle cache.
+- `preview.svg` writes are performed through the live handle and verified by read-back before `OK WRITE`.
+- Write logs include normalized path fields and SVG verification metadata.
+- Handle-relative output paths are not treated as mismatches against absolute display paths.
+- A forced read-back verification failure logs `FAIL`, records `Failed: 1`, and never logs `OK WRITE`.
+
+Expected fail behavior: tests fail if Preview Generator V2 silently falls back to session-only writes, logs `OK WRITE` before successful read-back verification, or resurrects the absolute-vs-handle-relative mismatch warning.
+
+## Coverage Notes
+
+Runtime JavaScript coverage from `npm run test:workspace-v2` included changed Preview Generator V2 files:
+
+- `(88%) tools/preview-generator-v2/PreviewGeneratorV2App.js - changed JS file with browser V8 coverage`
+- `(28%) tools/preview-generator-v2/PreviewGeneratorV2RepoAccess.js - advisory low coverage; cache restore branches include browser API and failure-path guards`
+
+`tests/playwright/tools/WorkspaceManagerV2.spec.mjs` is a changed test file and is not collected as browser runtime coverage.
+
+## Manual Test
+
+1. Open Workspace Manager V2.
+2. Pick the repo folder and open Asteroids.
+3. Launch Preview Generator V2 from the Workspace Manager V2 tool tiles.
+4. Generate the workspace preview.
+5. Expected: status log shows live handle restoration, write read-back verification, normalized path fields, and `OK WRITE Asteroids`.
+6. Expected: no absolute path versus handle-relative path mismatch warning appears.
+
+Out of scope: full sample smoke validation. Sample smoke remains skipped until a dedicated sample/runtime validation phase.
