Openhands Foundation

Use when building or porting an agent-chat frontend or the OpenHands Agent Canvas UI runtime — resumable dual-socket WebSocket event streams with REST-preload gating, rAF delta coalescing, id-dedup replay handling, optimistic message queues with server-echo matching, replay-safe client-action dispatch, reconnect ladders for parallel sockets, cron-preset automation schedules, browser-executed client tools with exactly-once launch ledgers, backend-split REST services with compensating import transactions, scoped query-cache invalidation, contract-fixture MSW mock fleets, desktop boot-splash launch chains, bootstrap version gates, local dev-stack launch orchestration, read-only terminal projection, rate-budgeted run-health dashboards, multi-backend selection with persisted health disable-latches, prompt-injection git controls, cookie-minted workspace file previews, host-login ACP auth probes, and manifest-owned command palettes.

OpenHands (Agent Canvas): agent-conversation UI runtime foundation

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: openhands; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@8511fff62d3084587cda1add483fe5ea9c8bfd7e.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Conversation stream kernel; Reconnect ladder; Delta batcher; Event store; Optimistic queue; Cron preset mapping; Client-tool round trip; Dev-stack orchestrator.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
