Run python tools/preview-prompt-timeline.py --bind 0.0.0.0 --port 8767 and open /workspace/. The original approved timeline remains available at /. The server exposes an explicit allowlist of concept files and pinned assets. All examples are synthetic; there are no application API calls, database access, real model downloads, or ComfyUI handoffs. Local file inspection previews an image in the browser without uploading it. Exports contain sample data only.

The sidebar opens Images, Prompt library, Tags & categories, Inspect a file, Activity, System and Design review. System includes Overview, Appearance, Sources & scans, Integrations, Auto-tagging, Maintenance, Backup & export, and Diagnostics & logs. The in-app Design review contains the feature map below.

Proposed direction

One application shell replaces separate Admin, Gallery and Metadata shells. Use the approved shared ComfyAssets theme: ComfyUI dark/light, blue primary actions, green positive roles, red negative roles and errors. Preserve all existing controls and services while making their scope clearer.

Browsing is image-led with readable thumbnails and one metadata inspector. Prompt library groups by positive; negative variants and runs share its gallery. The full selected negative appears directly beneath the positive in history. Favorites express preference independently of the existing quality rating. Collections organize projects without duplicating recipe text; saved views keep search/filter context. New capabilities are proposals, not implemented features.

Maintenance moves out of the browsing toolbar. Checks, impact preview, backups, and apply steps have separate responsibilities. Distinguish prompt text reuse from image-file duplicates, and metadata enrichment from thumbnail generation. No repeated global thumbnail-generation prompt on opening the gallery.

Send to ComfyUI

Use the same original paper-plane outline, blue accent and accessible role label on every positive/negative prompt block, including image details and the viewer. A pair action sends both. Preview destination and exact fields before applying; positive-only and negative-only actions leave the other role untouched. An explicitly empty negative means clear the target field; unknown metadata must never be interpreted as empty. Sending text neither queues execution nor replaces a workflow.

Production needs a shared host bridge with versioned payloads, origin validation, destination discovery, capability checks, disconnected-host handling, linked-input checks and acknowledgements. Preview actual target values and report success only after acknowledgement. Default to asking for a destination; never guess between multiple nodes or positive and negative encoder inputs. Verify Classic and Nodes 2.0 with both packs installed independently and together.

Implementation boundaries and test requirements

Keep Viewer.js 1.15.2 and the shared toolkit as reproducible pinned artifacts; this mock uses their actual checked-in files without modifying them. Preserve legacy routes during the transition, current node layouts/schemas, existing controllers where reusable, and all existing test/coverage gates.

The timeline needs persisted execution records to represent real runs. Saved views, collections, metadata review resolution, activity history, scheduled backups, portable JSON import, and the ComfyUI bridge need separate implementation and persistence work. Preserve source evidence and distinguish recorded from inferred metadata. Existing schema migration is automatic; old image enrichment remains an optional explicit scan. The one-time upgrade notice belongs in the new shell, with Scan and Later choices.

Implement in reviewed slices: shared application shell and inspector; reusable prompt blocks/send bridge; image workspace; grouped library/history; settings and maintenance; optional organization and workflow improvements. Write regressions first for production behavior. Retain Python, frontend unit, Chromium/Firefox/ WebKit/touch and managed Classic/Nodes 2.0 tests. Add behavior tests for shared filters, navigation state, viewer cleanup, interrupted jobs, dependency-safe maintenance, backup/restore, paired metadata and correct send destinations.

Screenshots in screenshots/ record the reviewed starting point. The approved standalone timeline in ../prompt-variant-timeline.html remains unchanged.
