Isolate transcript state per SDK context.
sendMessage() runs in an AsyncLocalStorage context, but getProject() returns one process-wide Project. When session B calls switchSession(), the global signal clears that singleton's sessionFile. If B then resolves its file while session A is still processing, A's later recordTranscript() still reads session A from its context but Project.appendEntry() uses B's cached file. Records can therefore be written to the wrong session file, and resuming a session can miss those records.
Make the Project transcript state context-scoped, including sessionFile and pendingEntries. The single process-wide pointerSessionId listener cannot provide isolation for overlapping SDK turns.

Thanks — I checked the mechanism and the finding is correct, so let me be precise about what it does and does not mean for this PR.
What it is not is something this PR introduces. The hazard comes from one process-wide
So the change fixes the sequential case, which is broken today in a way that silently empties a resumed conversation, and it does not claim to make overlapping turns safe. Context-scoping I have added this to the PR's known limitations so it is not lost. One note on the suggested direction, in case it saves someone time later: The trivial comment on the test is applied in 9413d0c: the first session's own records are now asserted, not just the absence of the second session's. |

Verified on head 9413d0c. I ran the focused test file (2 pass) and the negative control against main's sessionStorage.ts (the first test fails, the second session's transcript is empty), so the test is red-first.
The mechanism is correct:
switchSessionwrites state before emitting (src/bootstrap/state.ts:541-554), so the listener re-resolves against the new id.- v2 calls
switchSessionwith the id it already has before every turn (src/entrypoints/sdk/v2.ts:365). The same-id guard is what keeps those turns from dropping buffered entries. regenerateSessionId()does not emit the signal, but its call sites are covered: the clear path resets the pointer explicitly (src/commands/clear/conversation.ts:220), and the query path callsswitchSessionimmediately after (src/entrypoints/sdk/query.ts:674-678), which the listener follows.- Dropping
pendingEntrieson a real switch matches whatresetSessionFilePointeralready did on the CLI paths (src/utils/sessionStorage.ts:2217), so no behavior change there.
Of CodeRabbit's two comments: the retention assertion it asked for is in this head, and the major one is the overlapping-turn hazard the Notes already scope out (pre-existing: one process-wide Project with context-scoped session ids).
One robustness gap in the test wiring:
sessionSwitchRegistered is set once and never cleared, but resetStateForTests() clears the signal's listeners (src/bootstrap/state.ts:1044). Test files share one bun process, so any test that creates the Project singleton and later calls resetStateForTests() leaves this module believing it is registered while its listener is gone. Pointer-following then silently stops, and the sessionSwitch tests will fail confusingly in a full-suite run. resetProjectForTesting() re-reads pointerSessionId but cannot revive the listener. onSessionSwitch returns an unsubscribe function: resetProjectForTesting() could call it, clear the flag, and let the next getProject() re-register. A stale unsubscribe on a cleared signal is a no-op, so that also heals the resetStateForTests() case.
|
Thank you for verifying it to that depth — the The robustness gap is real and fixed in 262d801, the way you described: I added a test for that order rather than only the fix, since the failure it prevents appears in a full-suite run and nowhere else: create the Project, clear the signal under Preflight re-run at this head: One thing I should flag myself: CI has not run on this PR at all — only CodeRabbit has reported. #2252 got the full matrix, so I assume this one is waiting on a maintainer to approve workflows for a fork. Happy to do anything that helps there. |
Project.sessionFile is resolved once and cached for the life of the process. Every CLI path that changes the active session resets it by hand straight afterwards - sessionRestore.ts, /clear and print.ts all call resetSessionFilePointer right after switchSession, and its own docstring says that is when to call it. The v2 SDK cannot: unstable_v2_createSession hands back a session object and the switch happens inside sendMessage, leaving the embedder no moment to hook. So a second session created in one process went on writing into the FIRST session's file. Its records carried their own sessionId, so nothing looked wrong until something tried to resume it - resolveSessionFilePath found no file, the resume came back with zero prior messages, and the conversation was gone. Measured in an embedder: one project directory, one .jsonl, and inside it three sessions' records - 3979, 917 and 348 - while two of the three had no file of their own. An interrupt resumed the newest and silently started from nothing. Subscribing to the existing onSessionSwitch signal resets the pointer only on a real change, because v2 calls switchSession before every turn with the id it already has and resetting each time would drop buffered entries and re-resolve the same path for nothing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Review follow-up. The test showed that the second session's records do not leak into the first session's file, but not that the first session still holds its own - so a change that dropped them both would have passed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Review follow-up. resetStateForTests() calls sessionSwitched.clear(), which drops every listener at once. Remembering only "I am subscribed" left this module believing it still followed switches while its listener was gone, and since test files share one bun process that silently stopped pointer-following for every test afterwards - failing the switch tests in a full-suite run and nowhere else. onSessionSwitch returns an unsubscribe function, so resetProjectForTesting now gives the subscription up and forgets it, and the next getProject() registers afresh. A stale unsubscribe against an already-cleared signal is a no-op, which heals the resetStateForTests() case as well as its own. The added test reproduces that order: create the Project, clear the signal, let the file's own setup run again, then check a second session still gets its own transcript. With the unsubscribe neutralised it is the only test that fails. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Restore the original session project directory.
If the active session has a non-null project directory before this test, switchSession(originalSessionId, null) changes its transcript path for later tests. Save getSessionProjectDir() in setup and pass the saved value during cleanup. As per path instructions, review tests for “isolation of global/env/config state.”

Cover pending entries across a same-ID switch.
The test flushes before the second switch, so it cannot detect a listener that calls resetSessionFile() on every switch and clears pending entries. Add a buffered non-user/non-assistant entry before the same-ID switch, then materialize the file and assert that the entry is present.
This is essential regression coverage for the changed session-routing behavior.

Invalidate the cached pointer when the project directory changes.
switchSession() updates the project directory even when the session ID stays the same. The session-storage listener checks only the ID, so a same-ID switch can retain Project.sessionFile from the old directory. The SDK query path can perform this switch without calling resetSessionFilePointer().
Track the project directory or resolved transcript path with pointerSessionId. Retain the pointer only when both values match. Preserve pending entries when handing off to a different directory; resetSessionFile() clears them.

Update the session-storage listener’s pointer-retention check to compare the
project directory or resolved transcript path as well as sessionId, retaining
Project.sessionFile only when both match. When the directory changes, invalidate
the cached pointer without clearing pending entries; avoid using
resetSessionFile() for this handoff.

Preserve buffered entries for the outgoing session before resetting the pointer.
recordAttributionSnapshot can run before the first user or assistant message. appendEntry then stores the snapshot in pendingEntries. A switch to a different session calls resetSessionFile(), which clears that buffer. If the original session later returns, its first user or assistant message materializes a file without the discarded entries.
Flush buffered entries to the outgoing session before clearing them, or retain buffers keyed by session. Do not carry them into the new session.

Review comment at @src/utils/sessionStorage.ts around lines 811 - 816:
Update the session-switch flow around `pointerSessionId` and
`project?.resetSessionFile()` to preserve any `pendingEntries` for the outgoing
session before resetting the file pointer. Ensure those buffered entries are
associated only with the outgoing session and are not carried into the new
session.

Summary
sessionStoragenow subscribes to the existingonSessionSwitchsignal and resets the cached session-file pointer when the active session actually changes.Project.sessionFileis resolved once and cached for the life of the process. Every CLI path that changes the active session resets it by hand straight afterwards —sessionRestore.ts,/clearandprint.tsall callresetSessionFilePointerright afterswitchSession, and its docstring says that is when to call it. The v2 SDK cannot:unstable_v2_createSessionhands back a session object and the switch happens insidesendMessage, leaving an embedder no moment to hook. A second session created in one process therefore went on writing into the first session's file.Impact
sessionId, so nothing looked wrong until something tried to resume the newer session:resolveSessionFilePathfound no file for it, the resume came back with zero prior messages, and the conversation was gone. Measured in an embedder: one project directory, one.jsonl, and inside it three sessions' records — 3979, 917 and 348 — while two of the three had no file of their own. An interrupt resumed the newest and silently started from nothing.getProject(), and uses the already-exportedonSessionSwitchhook, so no new plumbing. It resets only on a real change, because v2 callsswitchSessionbefore every turn with the id it already has and resetting each time would drop buffered entries and re-resolve the same path for nothing.resetProjectForTestingre-reads the session the pointer belongs to, since the listener outlives the singleton it resets and cannot be unsubscribed from there. The CLI paths that already callresetSessionFilePointerkeep working — the extra reset is a no-op once the pointer has moved.Testing
I ran the required local preflight, with one documented exception below.

Every segment of the suite passes on its own, and all segments together take about nine minutes, so the stalled runs consumed roughly 27x the suite's entire work without completing. I did not isolate the file: the stall occurs wherebun testwrites only to stdout, which is block-buffered when redirected, so the last visible output is unrelated to where execution stopped. Happy to open this as a separate issue with the measurements.The steps inside

It is flaky — running thesrc/servicessegment three times on cleanmainwith no changes, it passed twice and failed on the third run; in isolation it passes 3/3.

follow-up work or known limitations: this fixes where records are written. It does not change
resolveSessionFilePath's behaviour for transcripts already interleaved by the old code; such a file keeps every session's records, and only the session whose id the file is named for resolves to it.It also does not make OVERLAPPING turns safe, raised in review and confirmed: one process-wide
ProjectcachessessionFilewhile session ids are context-scoped, so a turn still in flight in another context can append through a pointer the newer session resolved. Before this change the pointer never moved at all, which is the bug fixed here and loses a whole transcript; after it, the remaining exposure is interleaving between concurrent v2 sessions. MakingProject's transcript state context-scoped is the real fix and belongs in its own PR with its own concurrency tests.Summary by CodeRabbit
