FE-1575: Resume one Brunch workpiece and Petrinaut document across tabs by lunelson · Pull Request #9537 · hashintel/hash

lunelson · 2026-09-04T09:54:15Z

🌟 What is the purpose of this PR?

Determine whether one canonical Brunch conversation can maintain a useful Markdown workpiece, make one meaningful change to the Petrinaut document open in the browser, and resume the same coherent conversation/workpiece/document bundle in another tab.

This joins the real browser panel to the mounted Flue conversation route introduced by the parent PR. The retained two-tab witness establishes single-fixture browser-backed viability: one honestly labelled prepared crew-reservation case gained exactly one weight-1 input arc from Dispatch crew available to Start final inspection, then reopened and continued without duplicate preparation, mutation, or identity drift.

This does not establish automatic full-net projection, capture-backed provenance, broad scenario coverage, behavioral execution, remote durability, or concurrent collaboration.

🔍 What does this change?

Adds a stable, explicitly test-authored crew-reservation fixture with distinct fixture, conversation, workpiece, and Petrinaut document identities.
Delivers prepared workpiece revision zero exactly once as a tagged, idempotent Flue system/dispatch signal and selects later genuine assistant workpiece revisions without rewriting history.
Exposes only canonical Petrinaut document read and addArc operations for this fixture, normalizes the narrow provider input exercised by the witness, and returns correlated client-tool results through the same Flue route.
Adds a runtime settled manifest that advances only when conversation, workpiece, mutation result, and document state form one observable coherent bundle; stale or partial state remains visible and cannot replace the prior settled bundle.
Adds a labelled fixture selector and status banner, automatic local document persistence, same-fixture second-tab recovery, focused failure tests, user documentation, a Petrinaut changeset, and retained browser evidence.

🏗️ Agent notes

Mission contract

Imperative: Determine whether one canonical Brunch conversation can maintain a useful Markdown workpiece and drive a meaningful browser-side Petrinaut change without reviving a comprehensive typed domain IR. The visible advance is: Brunch edits the net being viewed from the conversation, and the work survives closing the tab.

Throughline: Stable prepared-fixture selector → distinct fixture/document/conversation identities → idempotent tagged revision-zero dispatch → canonical Flue history hydration → latest eligible Markdown workpiece recovery → one realistic confirming turn → fixture-scoped canonical document read and addArc request → browser validation/execution → original call-id result through the same Flue route → coherent settled manifest → second-tab reopen and real follow-up in the same conversation.

Proof: The corrected production-browser witness records one prepared source, one model-produced revision, one canonical weight-1 input arc, one unique correlated successful mutation result, matching settled identities/hashes in Tab B, and a completed non-mutating follow-up without duplicate preparation or mutation. Focused tests cover preparation idempotency, append-only workpiece selection, tool scoping, call/result correlation, no-op and rejected mutations, mismatch refusal, and content-addressed fallback to the prior coherent document. The proof is limited to this prepared local fixture.

Constraints: Flue remains the canonical conversation log; Markdown remains the semantic workpiece; Petrinaut owns schemas, validation, mutation, and document state; fixture, conversation, workpiece, and document identities stay distinct; the browser uses the parent PR's mounted /agents/chat/:instanceId transport; construction tools remain unavailable to unrelated conversations; no second event log, comprehensive process ontology, graph database, workflow engine, explicit Save flow, or remote durability claim is introduced.

Fog-line: The narrow shallow addArc carrier succeeded, including provider string-to-number normalization, but broader nested provider schemas remain unproved. The witness found message id plus SHA-256 sufficient for this fixture's workpiece revision and found localStorage mirroring sufficient for this same-browser two-tab path; neither result proves broader revision storage, concurrent editing, or cross-store transactions.

Stop or reorient: Stop if preparation hides authorship, identities collapse, traffic bypasses the mounted Flue route, transcript prose replaces the workpiece as construction input, parser acceptance substitutes for semantic correspondence, call ids or document targeting are lost, partial state advances the settled manifest, stale Tab B state is silently selected, fixture-only mutations leak to ordinary conversations, or the work widens into later provenance/projection/deployment missions.

Deferred: Mission 7 owns capture-backed visible why/provenance and broken-link refusal. Mission 9 owns repeatable automatic projection and broader nested provider-schema classes. Remote replacement durability remains with Mission 8. Concurrent editing, cross-store commit machinery, and promotion of this prepared fixture re-enter only under observed strain or a named later consumer.

Implementation record

The accepted witness used the production dev processes behind yarn dev:brunch, a fresh Playwright context, the mounted Flue route, a real configured provider credential, and ?brunch-fixture=crew-reservation-v1.
Canonical conversation: conv_01M1NV5WZETMYEGGMFXNYDSTRS.
Correlated mutation call: toolu_01BQukCZTAhJ64VNE7oC1CWG.
The provider emitted arc weight "1"; only the fixture's canonical Petrinaut tool input is normalized to numeric 1. No broader nested-input repair is claimed.
The first browser witness is retained as immutable history but superseded for acceptance because its assistant workpiece mislabelled authorship and its correlation artifact omitted parsed canonical input. The r2 witness corrects both issues.
Cold-reader semantic adjudication and the product-manager demo remain human-reserved acceptance gates. No persona suite replaced them.

⚠️ Known issues

Mission closure still requires the cold-reader adjudication and product-manager demo listed above.
The proof is local-only. Mission 8 stopped before remote deployment, so remote replacement durability is not claimed.
The corrected r2 witness supersedes the first retained witness for acceptance.
App-wide lint retains pre-existing warning-only findings; this PR introduces no lint errors.

🐾 Next steps

Mission 7: make every consequential element in the demo net resolve to exact conversation evidence or visibly refuse.
Mission 9: broaden this viable mutation seam into repeatable, traceable projection of one meaningful region.

🛡 What tests cover this?

Core workpiece parsing, provenance, hashing, and latest-eligible revision selection.
Prepared-signal idempotency and built-agent read/mutation/continuation integration.
SDCPN fixture-only tool advertisement and canonical schema derivation.
AI SDK transport projection, input normalization, deterministic submission keys, and client-tool history correlation.
Petrinaut mutation application, rejected inputs, duplicate/no-op handling, and exact document structure.
Website fixture preparation, bundle resolution, stale/partial-state refusal, settled-manifest advancement, history hydration, and second-tab identity continuity.
The affected Brunch, transport, plugin, Petrinaut, and website builds, type checks, and lint checks passed on 2026-09-04.

❓ How to test this?

Run yarn dev:brunch.
Open http://127.0.0.1:4915/?brunch-fixture=crew-reservation-v1.
Confirm the fixture is visibly labelled test-authored/prepared and the target input arc is absent.
Tell Brunch that final inspection uses the single dispatch crew and sign-off releases it.
Wait for the coherent bundle to settle; confirm exactly one weight-1 input arc now connects Dispatch crew available to Start final inspection.
Open the same URL in a second tab and confirm the fixture, conversation, workpiece, document, and settled-manifest identities match.
Submit a non-mutating follow-up in Tab B and confirm Brunch replies in the same conversation without another prepared source or addArc call.

📹 Demo

The corrected witness includes Tab A before/after and Tab B screenshots, canonical Flue snapshots, document definitions, settled manifests, correlation artifacts, workpieces, and checksums.

…nsport Prepare one honestly labelled crew-reservation fixture whose starting workpiece enters canonical Flue history exactly once as a tagged system dispatch signal with idempotent retry, scope the read/`addArc` client tools to that fixture, settle a runtime manifest only after conversation, workpiece, and document state are observable, and surface a visible refusal when the mounted Brunch route is absent. The fixture rides Mission 5's landed browser `ChatTransport`: the panel transport keeps the conversation tracker and accepts fixture-scoped client tool names as an option, the history hook keeps the live observation and additionally exposes the observed snapshot with its offset, and AI SDK user sends carry a deterministic idempotency key. The real two-tab witness remains blocked on the configured Anthropic credential; the blocker and handoff are recorded in the FE-1575 evidence note. No persona testing was run.

PR Summary

Medium Risk
Changes span canonical workpiece selection, client-tool correlation, and browser settlement state, but scope is a local prepared fixture with extensive tests rather than global conversation behavior.

Overview
Mission 6 wires a labelled crew-reservation demo so one Flue conversation can keep a Markdown runbook-ir workpiece, apply a single browser addArc mutation, and reopen the same conversation/workpiece/document bundle in another tab.

Shared workpiece logic moves into @hashintel/brunch-agent/workpiece and app recoverRunbookWorkpiece (hashes, prepared vs model authorship). Runbook eval code delegates to that selector instead of duplicating IR parsing. Fixture-scoped client tools (getLatestNetDefinition, addArc) join the Flue client-tool allowlist for this mode only.

The Petrinaut local-storage demo gains preparation via an idempotent tagged dispatch signal, a runtime settled manifest (refuses partial or uncorrelated mutations), content-addressed document snapshots, configurable brunch panel transport, and UI to select and status the fixture. Transport/history paths add idempotency keys and fixture-aware client-tool projection.

Petrinaut / petrinaut-core patch reports duplicate AI mutations as no-ops (applied: false) so resume paths can tell real changes from idempotent retries. Hermetic and website tests cover preparation deduplication, settlement refusal, and cross-tab continuity; MISSION.md is recut to Mission 6.

Fixture query param is dropped

High Severity

Fixture mode is gated on a raw brunch-fixture query that the index route’s validateSharedExampleSearch contract does not own. Any Petrinaut search write replaces the URL with contract keys only, so the param disappears and the session drops fixture tools and the stable conversation id.

Fixture catalog omits docs reader

Medium Severity

The fixture replaces the browser client-tool catalog with only getLatestNetDefinition and addArc. The SDCPN plugin still mounts readPetrinautDoc as a client-awaiting tool, so a docs read cannot be executed or returned through the Flue route and the turn stalls.
