Web Workbench

The web workbench is a browser UI over the same ~/.lattice data as the CLI. It reads local files directly and never requires an account.

Start the workbench

# Start the workbench (default port 14527)
ltc web
# Use a custom port
ltc web --port 8080
# Do not open a browser automatically
ltc web --no-open

The workbench serves http://localhost:14527 by default. Routes are URL-driven, so browser back and forward work and any view can be linked directly.

Four views

View	Question it answers
Global	How do projects, tasks and specs connect?
Task	What is the goal, PRD, design and progress of this task?
Project	What does this repository know and what is active?
Spec	What rule applies here, and which tasks depend on it?

Press 1–4 to switch views. Clicking a node opens the detail panel without losing your place on the canvas.

Canvas and layouts

The canvas is a graph, not a dashboard. Edges show the current relation, and the minimap keeps orientation on large graphs. Three layouts cover different reading tasks:

Force — clustered overview of the whole graph.
Sequential — layered flow for reading dependency order.
Radial — one focus node with its neighborhood around it.

Search and filters

Shortcut	Action
`⌘K` / `Ctrl+K`	Focus the sidebar search
`⌘P` / `Ctrl+P`	Open global search
`⌘F` / `Ctrl+F`	Toggle canvas search
`Esc`	Close search or the detail panel

The sidebar filters by node type, task status and spec scope. Keyword search stays local and still works when semantic retrieval is unavailable.

Detail panels

Task — PRD, design, progress and checkpoints in one place.
Spec — scope, frontmatter, body and the tasks that reference it.
Project — Git state, registered paths and project relations.

Theme and layout

Light and dark themes can follow the system or be set manually. On narrow screens the desktop sidebars become drawers, while the canvas keeps the same interactions.

Routes

Path	View
`/`	Global relation graph
`/task/:taskId`	Task view
`/project/:projectId`	Project view
`/spec/:specId`	Spec view

Deep links open the same detail panel as clicking a node.

Public demo

The live demo runs the real workbench UI with mocked data. It is a static build: no login, no backend and no network requests. Refreshing resets all writes.
