fix(server): imported Claude Code sessions resume on their first follow-up - #15376
abderbejaoui wants to merge 3 commits into
Conversation
…ow-up An imported Claude Code session is written as a provider thread with a strong native ref, no conversation head and no provider turns. `openQuery` only resumed when one of those existed or this session instance had already opened the native thread, so the first follow-up reopened the session with a fixed `sessionId` and the CLI rejected it: "Session ID ... is already in use". `resumeThread` is how the orchestrator re-attaches a provider thread that already carries a native id. When the thread has never been bound by a provider session of ours (`providerSessionId === null`, the shape both import paths write), record its native id as adopted and let `openQuery` resume it. Threads this adapter minted keep their provider session id, so a retry after a failed first create still creates the session.

The first version keyed the resume decision on `providerSessionId === null` at `resumeThread`, but the orchestrator binds a provider session to the provider thread when it starts the run, before the turn-start service ever reaches the adapter, so the guard could not fire in production. Both import paths now stamp `nativeMetadata.nativeThreadOrigin = "imported"` on the provider thread they write, and `ClaudeAdapterV2.openQuery` reads it from the turn's provider thread next to the existing resume signals. The provenance is persisted with the row, so it survives idle release and a failed first follow-up, and threads this adapter minted carry no origin and keep creating their session.

…lier Rows written before the import origin existed carry no marker, so their first Claude follow-up still reopened the session with a fixed id. Both already-imported paths of AgentSessionImporter now load the thread's provider threads and stamp `nativeThreadOrigin: "imported"` on the row for the imported session when it is missing; rows that already carry it are left alone.

If the
orchestration_eventsinsert for the origin stamp fails before commit,stampImportedOriginOrWarnlogs the error and returns success. For anAlreadyImportedthread, the importer has already incrementedimportedCountand does not incrementskippedCount. When this is the only import outcome,WelcomeWizardmarks the project imported and skips it on same-session retries. The missing marker can leave Claude’s first follow-up, when no other resume signal applies, on the fixed-sessionIdpath instead of resuming the native thread. Report the stamp failure as incomplete so the project remains retryable.🤖 Prompt for AI Agents

At de8d700, the origin backfill runs through Is reimport an intentional requirement for those existing threads, or should direct continuation repair them?

Problem
Every imported Claude Code session fails on its first follow-up with
Session ID <id> is already in use, whether it came through the welcome wizard or a per-session import. The import writes the provider thread with a strongnativeThreadRef,nativeConversationHeadRef: nulland no provider turns. InClaudeAdapterV2.openQuery,shouldResumeis true only when a conversation head exists, this session instance already opened the native thread, orproviderTurnOrdinal > 1. None of those hold for the imported thread's first turn, somakeClaudeQueryOptionssendssessionIdinstead ofresumeand the CLI rejects the id it already owns.provider_resume_fallbacknever fires because the ClauderesumeThreadsucceeds; the failure comes later, at query open.Reported in #15243 with the CLI repro and logs; confirmed by triage on
mainatce90eec1f.Change
Both import paths now record where the native thread came from.
AgentSessionImporterand the orchestrator'simportedNativeThreadbranch stampnativeMetadata.nativeThreadOrigin = "imported"on the provider thread they write, next to the existingitemIdentityVersionmarker thatProviderTurnStartServicealready reads from the same object.ClaudeAdapterV2.openQuerytreats a provider thread carrying that origin as resumable alongside the three existing signals, so the first follow-up opens withresume: <session id>.Rows imported before this change carry no marker, so both already-imported paths of
AgentSessionImporter(the scanner'sAlreadyImportedoutcome and an existingv1_importthread) backfill it: they load the thread's provider threads and write oneprovider-thread.updatedevent stamping the origin when it is missing. The provenance lives on the persisted provider thread row, so it survives idle release and a failed first follow-up, and the orchestrator's run-start binding (providerSessionId,status, run ordinals) leaves it untouched. Threads this adapter minted carry no origin and keep taking thesessionIdpath, which is the failed-create retry the comment aboveopenedNativeThreadsprotects. Codex is unaffected: it resumes any native ref already.Triage named two directions. Honoring the stored
resumeCursorwould need the runtime row plumbed from persistence throughProviderTurnStartServiceinto the adapter, and recording a conversation head would driveresumeSessionAt, which needs a message id the import does not have. Stamping the origin the import already knows is smaller than either and keeps the adapter decision local.Review history: the first commit keyed the decision on
providerSessionId === nullatresumeThread. CodeRabbit pointed out that the orchestrator binds a provider session to the thread at run start, before the adapter is reached, so that guard could not fire in production; the second commit replaces it with the persisted origin.Scope and approval
Bug fix for the triaged issue #15243. Triage confirmed the failure on current
main, traced both code paths, and namedshouldResumeinClaudeAdapterV2.openQueryas the fix area. One underlying problem; the change touches the provider-thread contract (one optional metadata field), the two import paths, the Claude adapter, and their tests.Verification
