onepipeline-ui

The read API and browser view for onepipeline runs: an axum server wrapping the onepipeline SDK, plus the frontend that reads it.

The contract

docs/contract.md is the source of truth, quoted verbatim from the task that commissioned this repository. tests/contract.rs reconciles the code against it, so a route that exists in one and not the other fails the gate.

GET /healthz
GET /api/v2/runs                      # list w/ session attribution
GET /api/v2/runs/{run}                ?include_conversations=bool
GET /api/v2/runs/{run}/timeline       ?scope=run|node&node=ID
GET /api/v2/runs/{run}/conversations/{id}
GET /api/v2/runs/{run}/artifacts/{id}
GET /api/v2/events                    # SSE; fresh snapshot per connection

Every successful response carries the schema-version preamble — api_version, telemetry_schema_version (16), observed_at — with the payload flattened alongside it. Every failure carries {"error": {"code", "message"}}.

Payloads themselves come from the onepipeline SDK. Anything presentation-worthy lands there first, so the agent reading the CLI sees at least what the human in the UI sees; this crate owns the envelope, not the records.

The view

apps/dag-ui is the DAG Observatory: the browser view of the same runs, reading nothing but the contract above. It declares no schema, event name, or API path of its own — packages/dag-model holds the contract's client half, packages/telemetry-client is the only thing that speaks HTTP, and packages/dag-layout is the graph geometry. docs/dag-ui.md is its design record.

Install

Two deliverables, split by what they contain.

The read API, as the same prebuilt binary on three registries:

cargo install onepipeline-ui --locked  # from crates.io
pip install onepipeline-api-cli        # prebuilt wheel, no Rust toolchain
npm install -g onepipeline-api-cli     # prebuilt binary, no Rust toolchain

All three install one command, onepipeline-api:

onepipeline-api serve --runs-root ./runs

The view, as a static bundle on npm alone:

npm install onepipeline-ui             # the built frontend under dist/

That package installs no command — it is dist/, to be served statically.

Prebuilt archives and their .sha256 checksums are also attached to every GitHub Release.

Develop

just bootstrap        # from a clean clone
just check            # the deterministic gate, every project
just gate             # `check` plus the llmlint LLM-judge tier — the pre-push bar
just dag-ui-screens   # photograph the view at every viewport into a gallery

just --list is the full command surface. AGENTS.md is the durable instruction layer for humans and agents working here.
