fix(testkit): #339 follow-ups — model the real chat.send contract, read the active history entry - #523
Conversation
… read the active history entry
nextChatSend parsed chat.send input as {content: string}, so a send carrying
content parts (attachments) or the legacy text field threw a raw ZodError. It
now parses the contract shape (text?, content?: string | ChatContentPart[]) and
returns the whole frame, so callers narrow to what they care about.
panelSessionId scanned the whole persisted history for the first panel route,
disagreeing with currentHref, which reads entries[index]. After a session switch
it resolved a stale session, so panelDraft/untilPanelDraft read the wrong
session's draft. It now reads the active entry.

📝 WalkthroughWalkthroughThe PR exports the shared chat input schema, updates RPC wire parsing to preserve structured fields, and adds end-to-end tests for grabbed-element attachments and session-specific draft persistence. ChangesChat and panel end-to-end behavior
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR corrects chat-send handling for attachment content and session-history selection, with the reported checks passing. It is mergeable with explicit owner awareness that the panel-session-switch integration test still needs follow-up on its browser page creation pattern. Possibly related PRs

- The new regression test exercises only the content-parts branch. Removing this newly added legacy
textbranch would leave the suite green, even though handling text-only sends is one of the contract mismatches this change fixes. Add a wire-watcher regression that sends viatextand asserts the returned frame.

… share the real chat.send schema Copilot review on #523 flagged two weakenings. chat-send-parts reached past the UI into the composer's hidden sr-only file input, so it stayed green even with the accessible control broken. It now clicks the "Add attachment" button and answers the file chooser, asserting the button is enabled first. rpc-wire re-declared a looser copy of the chat.send input schema: it accepted an empty string, an empty parts array, more than 16 parts, and a frame carrying neither text nor content. It now parses against the contract's own ChatSendInput, which is exported for it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Follow-up to #514. Two reviewer findings on code that PR introduced, both real, both now covered by a regression test that fails without the fix.
1.
nextChatSendmis-modelled thechat.sendcontractpackages/extension-testkit/src/rpc-wire.tsparsedz.object({content: z.string()}). The actual contract (packages/contract/src/contract.ts:30-34) is:contentis optional and may be an array of content parts, with a legacytextalternative. So the helper threw on any send usingtext, and on any send carrying attachment parts — a path #513 (grabs as attachments) made reachable. It was green only because every existing caller happens to send a plain string.Before the fix,
chat-send-parts.it.test.tsdrives a real grab attachment through the composer and gets:Fix: model the full contract in the returned frame, reusing the real
ChatContentPartSchemafrom@conciv/protocol/chat-typesrather than a hand-copied shape, with the exported type derived viaz.inferso it cannot drift from the schema.Seven of the ten call sites read only
.transport; a string-only helper would still have had to parse content and would still have thrown on an attachment send for reasons unrelated to what those tests assert. The threecomposer-rich-inputsites that do read.contentkeep their strict assertion (toBe('helloん')) — the frame value is nowstring | ChatContentPart[] | undefined, so if the composer ever stopped sending plain string content those fail loudly rather than passing.2.
panelSessionIdread the wrong history entrypackages/embed/tests/e2e/helpers/navigation.tsreturned the first panel route anywhere in history instead of the active entry atpersisted.index, so it disagreed withcurrentHref. After a session switch it resolves a stale session, andpanelDraft/untilPanelDraftthen read the wrong session's draft.panel-session-switch.it.test.tsboots two harness sessions, drafts in the first, switches via the session picker, and asserts the helper reports the session the panel is actually on:Fix: read
entries[persisted.index], matchingcurrentHrefsemantics.This flaw was inherited — the pre-#339 code scanned the same way — but #514 rewrote that function and carried it forward. No existing test depended on the scan:
draft-selection,reload-continuity,composer-rich-inputandnative-widgetall pass unchanged, because each only ever has one panel entry in history, which is why it stayed invisible.Evidence
Both fixes revert-checked: with only the source hunks reverse-applied and the tests untouched, each new test fails again with the output above.
Gates: full serial embed suite (101), extension-testkit, apps/conciv, recorder, tanstack — all green. Whole-repo typecheck 96/96 against current
main. Lint 101/101, format clean,fallow auditzero introduced. 3x serial green over both new files and every dependent suite.Note
The image-attachment path can't be driven end to end from the embed suite:
createFakeHarnesshardcodesimageInput: falseand neitherbootCoreKitnorbootEmbedKitexposes an override, so the composer never installs the image adapter. This test uses a grab document attachment, which reaches the same array-content wire shape. A text-only attachment would not have reproduced it, becausecontentFromPartsinpackages/client/src/chat-connection.tscollapses all-text parts back into a string. Covering image parts in an IT would needimageInputthreaded through the fake harness — not done here.🤖 Generated with Claude Code
