Fixes #13492

Clause-②: no
Metadata-protocol: none

What changed

An assistant answer now renders its text and its charts in the order the stream produced them. A chart the model drew before writing its analysis shows first, so an open-ended analysis in the console's assistant panel puts its chart on the first screen (the acceptance objectstack-ai/cloud#3072 sets). Before, mapMessages joined every text part into one content and lifted every data-chart part into one trailing charts[], and ChatbotEnhanced rendered the whole text first, so the chart always landed below every paragraph.

• mapMessages.ts: extractCharts now records, on each chart, where it arrived among the text parts: textOffset = the length of the text that extractText joined before it. Tool, step and reasoning parts add nothing. Only when content IS that join; a legacy string content is not built from the parts, so its charts carry no offset.
• ChatbotEnhanced.tsx: a new optional ChatChart.textOffset. layoutAnswer splits content at the offsets into text runs and chart runs; each text run renders through its own MessageResponse (so long-answer folding and record links work in every run), and each chart run through the same chart markup as before, now in AnswerCharts. The streaming caret rides the last text run, where it sat before. Charts render in the same tree position whether or not prose has arrived, so a chart drawn before the first word keeps its mounted node when the text streams in.
• Backward-compatible: content and charts keep their shape. A chart with no textOffset (a host-built message, the legacy string-content shape) or one past the end of the text trails all of it, which is exactly the old layout; a message with no charts renders the same DOM as before. textOffset is a placement key and never reaches the chart schema handed to SchemaRenderer.

The card's acceptance, item by item

Acceptance	Pinned by
parts data-chart, text: the chart renders before the text	data-chart then text: the chart renders before the analysis
parts text, data-chart, text: the three in that order	text, data-chart, text: the three render in that order
a re-hydrated stored message keeps the order	useObjectChat.chartOrderRehydrate-13492.test.tsx (API mode, stored message with parts through the hook and into the bubble) and re-mapping a restored message (same parts) yields the same placement
long-answer folding (objectui#13032) does not regress	objectui#13032 does not regress: the long analysis after a chart still folds once the stream ends, plus the unchanged chatAnswerLayout-13032.test.tsx
record links (objectui#13037) do not regress	objectui#13037 does not regress: a record link in the text after a chart opens through the host opener, plus the unchanged chatRecordLink-13037.test.tsx
staging re-test with 「帮我分析一下客户」	NOT MEASURED: staging reaches this through cloud's objectui pin; re-run after the pin moves past this merge

New files: mapMessages.chartOrder-13492.test.ts (6 tests), ChatbotEnhanced.chartOrder-13492.test.tsx (7, one a CONTROL for the old layout), useObjectChat.chartOrderRehydrate-13492.test.tsx (2). mapMessages.test.ts gains the textOffset in the one test that pins a chart's exact shape.

Verification (local, head cb0af96)

All runs from the repo root under the shared verify lock.

• pnpm exec vitest run --maxWorkers=2 packages/plugin-chatbot/: Test Files 82 passed (82), Tests 787 passed (787).
• The 54 test files in packages/app-shell/src and apps/console/src that import @object-ui/plugin-chatbot (resolved to its src by the root config's alias): Test Files 54 passed (54), Tests 582 passed (582).
• pnpm turbo run type-check --filter=@object-ui/plugin-chatbot (builds the dependency closure, then tsc --noEmit && tsc -p tsconfig.test.json): exit 0 after one fix to the new re-hydrate test (it now hands the hook's messages through toRuntimeMessages, as hosts do).
• eslint --no-inline-config on the six touched source and test files: 0 errors; the 11 warnings are all on lines this PR does not touch.
• node scripts/check-changeset-presence.mjs and node scripts/check-changeset-no-major.mjs: pass. pnpm check:new-line-citations: 0 new citations. check:vi-mock-specifiers, check:vi-mock-inherit, check:vi-mock-override-shape, check:test-path-roots, check:control-bytes, check:ui-root-lookups, check:unreferenced-sources: all exit 0.
• Reverse verification, both through ablation-replace.mjs with the fix committed and restore proven (blob equals HEAD, git diff HEAD empty):
  • renderer: layoutAnswer ignores textOffset (every chart trails the text) ⇒ 6 of the 9 render and re-hydrate tests turn red; the record-link test, the old-layout CONTROL and the mapper tests stay green, as they should.
  • mapper: the textOffset spread deleted ⇒ 13 tests red across the four files, including the existing exact-shape test; the legacy no-offset test stays green.
• NOT MEASURED locally, left to CI: the sharded full pnpm test, repo-wide pnpm lint, builds and the remaining check:* gates.

Acceptance notes

• No reload path in this repository restores a chart today, so on reload the chart is missing, not misplaced. The server keeps a conversation as Vercel ModelMessages (IAIConversationService.addMessage in @objectstack/spec's contracts/ai-service.ts), which have no data parts. On the way back, app-shell's hydratedMessagesToChatMessages builds content and tool invocations only, and sanitizeChatMessagesForCache writes text and tool parts only. Read from code, not measured on staging; outside this card's file surface (packages/plugin-chatbot/src/**). A stored message that does carry its data-chart parts keeps its order (pinned above). Whether cloud's visualize_data result carries enough to re-derive the chart on reload is a cloud-side reading this session cannot reach.

• In an answer that interleaves text and charts, each text run folds on its own (a run taller than two viewport heights folds; a short intro above the chart does not). An answer with no chart, or with its charts after all the text, is one run and folds exactly as before.

• Docs: neither packages/plugin-chatbot/README.md nor content/docs/plugins/plugin-chatbot.mdx describes where charts render, so nothing there went stale; textOffset is documented on the ChatChart type.

• Adds no product-specific widget, dialog, hook or string (see AGENTS.md › Product-neutral renderer)

Reviewer of record: session_01XWGTsmqrtrt1Zqh1ioWqsT (seat 4). Implemented-by: session_01VWbYRWtBm3f8J2T8HAt97o on claude/project-thread-49319q. Card objectui#13492 (p1), claim 6393183623, report 6393359237.

1. Shape: draft, base main, Fixes #13492. Seven files (+548 −55), all under packages/plugin-chatbot/src/** plus one changeset, inside the claim.
2. Card against diff:
   • Mapper: extractCharts now counts the text parts it walks past and stamps each chart with textOffset. That count matches extractText's join('') exactly, so an offset is an index into content. It is set only when content is built from the parts (anchored: typeof msg.content !== 'string'); a legacy string content gets no offset.
   • Render: layoutAnswer splits content at the offsets. It clamps offsets to [0, content.length], uses a stable sort, merges charts at the same offset into one block, and drops whitespace-only slices. A chart with no offset trails all the text, which is the old layout byte for byte, so a host that builds ChatMessage itself is unaffected.
   • Backward compatibility: content and charts keep their shapes; textOffset is optional and never reaches the <chart> schema. The claim's backward-compatibility line holds.
   • Non-regression: the streaming cursor rides the last text run. RecordLinkContext wraps every run (chat: a record link in an assistant answer opens that record inside the console (today every link is an external-link dialog and a new tab) #13037). Each run is its own MessageResponse, so a long answer folds per run once streaming ends (chat: an assistant answer in the side panel — headings at chat size, wide tables fit the narrow panel, long answers fold, the scroll-to-bottom button never covers text #13032); both are pinned in ChatbotEnhanced.chartOrder-13492. The tool-call placeholder branch is reachable only when there is no visible prose, as before.
   • The card's 验收: chart then text renders the chart first, and text / chart / text keeps that order (render and mapper pins). The re-hydrate pin runs a stored API-mode message with parts through useObjectChat into the bubble. Ablations (renderer ignores the offset; mapper drops it) turned 6 and 13 tests red respectively.
3. Gates on this head: 33 check-runs success and 3 skipped (coverage jobs, dependabot). mergeable_state: behind only because main moved; the merge queue rebuilds on current main. Locally: plugin-chatbot 82 files / 787 tests, and the 54 app-shell + console files importing it (582 tests), are green. Type-check and eslint pass (0 errors).
4. Accepted deviations: none.
5. Out of scope:
   • Charts after a reload, filed separately. The dev read that no objectui reload path restores a chart at all. The server persists ModelMessage with no data parts; app-shell's hydratedMessagesToChatMessages and the chat cache sanitizer keep only text and tool parts. So after a reload the chart is missing, not misplaced. The card's re-hydrate line is met for messages that keep their parts.
   • Staging re-test: NOT MEASURED. It runs after cloud's pin moves past this merge, on cloud#3072.
6. Landing: not governed. Changeset: @object-ui/plugin-chatbot patch, Clause-② no / Metadata-protocol none; it matches the diff. The maintainer's standing landing word was given in this seat's project thread at 2026-10-25T01:48Z, so the seat lands it.
