FE-814, FE-758: Petrinaut Brunch Actual Mode by kube · Pull Request #8829 · hashintel/hash

kube · 2026-06-04T21:46:26Z

🌟 What is the purpose of this PR?

Adds a first Actual Mode to Petrinaut: a read-only view of a live execution streamed by a host, instead of a simulation run inside Petrinaut.

The first host is Brunch. The demo website exposes /brunch?sse=<stream URL>, loads the Petri net definition directly from the Brunch stream, and renders the run live with a scrubbable timeline and an event log.

🔍 What does this change?

@hashintel/petrinaut-core — new transport-neutral actual-mode module: event/marking schemas, marking reconstruction from initial_state + firing effects, timeline point generation, a SimulationFrameReader adapter, and recording export/retime helpers.
@hashintel/petrinaut — third global mode Actual: ActualModeContext (host contract), a mode-routed ExecutionFrameProvider feeding both the canvas and the timeline chart, Actual Timeline and Events bottom tabs (with stream/net export), and read-only enforcement.
Redesigned timeline series selector (also used in Simulate mode): searchable multi-select dropdown, hover-to-hide actions with an undo grace period, and a "+N more" overflow chip.
apps/petrinaut-website — Brunch demo route with a reconnect-safe EventSource provider, temporary Brunch protocol schemas + auto-layout, a Vercel rewrite for /brunch, and a local SSE fixture (yarn brunch:fixture) that can also replay exported recordings.
User docs: new actual-mode.md page, registered for the in-app AI assistant; related pages updated.

⚠️ Known issues

The Brunch protocol (event names, payload shapes, endpoint layout) is experimental and owned by the demo website until standardized with the Brunch team.
Brunch nets are extension-free: no colours, stochasticity, dynamics, or parameters.
Marking reconstruction replays from the start per frame — fine at demo scale, O(n²) for very long streams (flagged with TODOs in code).
The canvas follows live updates only while the Actual Timeline tab is mounted.

🐾 Next steps

Standardize the Brunch/Petrinaut protocol and move its schemas into petrinaut-core (including SSE event ids / resume semantics instead of replay-from-start on reconnect).
Add a prefix-marking cache or incremental timeline reader to remove the O(n²) replay.
Move follow-live/scrub ownership into ExecutionFrameProvider so the canvas keeps following live updates regardless of the active bottom tab.
Parse recording definitions through sdcpnSchema so file-format defaults apply to imported recordings.
Split an ActualView out of the shared workspace (sibling of SimulateView) to remove the remaining per-mode conditionals.
Replace the temporary /brunch path check with a real router in the demo app.
Legend: hover a series to highlight its trace in the chart.

🛡 What tests cover this?

petrinaut-core: Actual-mode unit tests (recording round-trip, strict payload validation, retiming, marking/timeline reconstruction).
petrinaut: ExecutionFrameProvider adapter tests and timeline series selector interaction tests (hide/undo grace period, batch toggling, search clearing).
Existing suites across all three packages remain green.

❓ How to test this?

yarn workspace @apps/petrinaut-website dev and, in another terminal, yarn workspace @apps/petrinaut-website brunch:fixture.
Open the /brunch?sse=… URL the fixture prints.
Watch the net update live; scrub the Timeline tab, inspect the Events tab, and try Export Stream / Export Net.
Replay an export: yarn workspace @apps/petrinaut-website brunch:fixture --recording=<file>.petrinaut-actual.json.

PR Summary

Medium Risk
Large cross-package feature touching editor modes, timeline/frame plumbing, and experimental Brunch SSE protocol; read-only paths are new but marking replay is O(n²) at scale and reconnect semantics are temporary.

Overview
Introduces Actual mode: a read-only, host-fed live execution view (first integration: Brunch SSE) alongside Edit and Simulate.

petrinaut-core adds an actual-mode module—schemas, marking replay from firing effects, timeline points, a SimulationFrameReader adapter, and recording export/retime helpers—plus exports sdcpnSchema for validation.

petrinaut wires a third global mode when ActualModeContext is available: ExecutionFrameProvider routes simulation vs Actual frames to the canvas and timelines; bottom panel gains Actual Timeline and Events (stream/net export); read-only rules and mode selector enable Actual; timeline hidden-series state is lifted in editor context for a redesigned series selector shared with simulation.

petrinaut-website splits the demo into local-storage vs /brunch (Vercel rewrite), with BrunchActualModeProvider (EventSource, reconnect replay handling), temporary Brunch protocol parsing, and brunch:fixture for local SSE or recording replay.

Docs and AI assistant catalog gain actual-mode; minor version changesets for both packages.

Pull request overview

This PR introduces Actual Mode to Petrinaut (including a Brunch-backed /brunch demo route) so the UI can render and scrub through a host-provided execution stream, while also adding extension/capability gating (colors/dynamics/stochasticity/parameters) and read input arcs across both the editor and simulation core.

Changes:

Add Actual Mode context + timeline source and wire it into the editor UI (mode selector, bottom panel, timeline scrubbing).
Introduce extension settings / handle capabilities and apply them end-to-end (sanitized SDCPN snapshots, conditional UI surfaces, simulation + experiments + LSP diagnostics).
Add read input arc support across SDCPN types, parsing/clipboard, simulation semantics, editor rendering, docs, and tests.
