reconcilePhantomCommittedReservations emitted a task:reconcile-phantom-committed-reservation audit row every maintenance tick for the same orphaned committed reservations even when zero child rows were pruned (~19k no-op writes/day). Gate the audit emission on actual pruned work; the FN-7069 contract is unchanged (committed reservation stays committed so the ID is never reused).
clearPhantomExecutorBinding unconditionally unregistered held worktree paths from activeSessionRegistry, defeating the moveTask(preserveWorktree:true) the self-healing phantom reclaim pairs it with: re-dispatch then acquired a brand-new worktree instead of reattaching (FN-7249 lost its first worktree this way). Add a preserveWorktrees option that clears only the stale in-memory executor/lock bookkeeping and leaves the session-registry path entries intact; the self-healing caller opts in. Non-self-healing callers keep the default full-clear behavior.
## Summary
Task image artifacts can now complete the full loop: agents and chat
flows can register base64 image bytes, and task details can display
those artifacts with an expandable preview instead of leaving them as
undiscoverable metadata.
This keeps binary payloads on the existing managed artifact storage
path, validates that base64 payloads are real non-empty image data, and
documents the new `dataBase64` field for engine-tool callers. The task
details artifacts gallery now treats image cards as expandable while
leaving document, audio, video, and generic artifact cards on their
existing behavior.
## Validation
- `pnpm --filter @fusion/dashboard exec vitest run
app/components/__tests__/TaskDocumentsTab.test.tsx
src/routes/__tests__/artifacts-route-integration.test.ts
--silent=passed-only --reporter=dot`
- `pnpm --filter @fusion/engine exec vitest run
src/__tests__/agent-artifact-tools.test.ts --silent=passed-only
--reporter=dot`

## Summary by CodeRabbit
* **New Features**
* Added inline base64 (`dataBase64`) support for registering image
artifacts from agent tools, including task-scoped chat registration.
* Task details now allow expanding image media artifacts in a preview
lightbox with accessible keyboard interaction.
* **Bug Fixes**
* Improved verification for media streaming by validating raw binary
responses; added HTTP 200/404 coverage for image endpoints.
* **Documentation**
* Updated `fn_artifact_register` tool documentation to include the
optional `dataBase64` parameter.
* **Tests**
* Added coverage for base64 validation/error handling and lightbox
expand/close behavior (including Escape and Tab focus trapping).

Record skill-backed workflow nodes into workflowStepResults and teach task progress surfaces to include those graph-node records without re-showing disabled optional workflow checks.
- classify image artifact support as a minor feature changeset
- reject non-image, empty, and signature-mismatched dataBase64 payloads
- trap keyboard focus in the task image lightbox
- assert media streaming with raw image bytes

Classify write-capable graph nodes before handler dispatch and let executor adapters fulfill the declared worktree requirement, keeping custom-node execution out of lifecycle decision making.
Fusion-Task-Id: FN-7224
Move completed-step replay and proven-merge finalization into workflow-owned execution paths so graph restarts continue from live task projection instead of failing stale step nodes.
