PR #32122 real dev verification
main: d91915db9e; PR: 4354cad0fd28c602716ada962dacf309b0009a9f

Runtime setup:
git worktree add ../main github/main; vp i
main dev runner: serverPort=16733 webPort=8693 baseDir=/home/user/main/.t3
PR exact head checkout; vp i
PR dev runner: serverPort=13773 webPort=5733 baseDir=/home/user/t3code/.t3
Only one dev server ran at a time; main stopped by its captured process group.

Real history:
Created /home/user/import-verification as a git repo and added it through the web client.
Sent a Codex gpt-6.1-sol turn through the web composer; observed: import verification ready.
Created an unused session through real codex app-server initialize, thread/start, thread/name/set, with no turn/start.
Codex persisted the empty session as session_meta only; no fabricated transcript records.

main welcome import:
Selected import-verification; clicked Import threads and start.
Observed: Some history was not imported / 1 thread could not be imported.

Reimport retained a single imported thread. AlreadyImported outcomes count in importedCount by design.
Opened imported conversation in the web client; asked it to recall its prior sentence.
Codex gpt-6.1-sol replied: import verification ready.
Then created 99 more actual unused Codex sessions through app-server (99 session_meta records).
All 100 unused sessions were newer than the resumed real conversation.
Welcome scan displayed 101 sessions; import returned importedCount=1, skippedCount=0.
