One-time startup migration that scans ~/.rowboat/runs/*.jsonl and converts
each legacy run into the new event-sourced runtime, so existing chats and
agent history are visible and continuable after the runtime rewrite.
Mapping (a run is one whole conversation; turn boundaries are user messages):
- copilot_chat run -> 1 session (sessionId = original runId) + one turn per
user message (turn ids <runId>-tNNN).
- every other run -> a single standalone turn whose id IS the original runId,
so live-note (lastRunId) and background-task (runs.log)
history views resolve it via sessions:getTurn with no
renderer change.
- code_session runs are skipped (Code mode still uses the old runtime).
- convert.ts: pure convertRun(); synthesizes a reduceTurn/reduceSession-legal
event log (exact request refs, permission replay, denials -> runtime isError
results, reasoning parts preserved) and validates via the reducers before
returning.
- migrate.ts: defensive IO runner. Successful runs are moved to runs-archive/
(that move is the idempotency guard); failures are left in place (still
served by the runs:fetch fallback) and retried next launch. Per-run
try/catch never blocks boot. Writes config/runs-migration.json.
- main.ts: runs before sessions.initialize() and logs an [runs-migration]
summary (N turns across M sessions, skipped/failed counts).
- Tests: 13 cases over 4 real (redacted) run fixtures — conversion, session
chaining, deny->error, reasoning preservation, transcript fidelity,
archive-on-success, skip, quarantine, idempotency, and read-back through the
real FSTurnRepo/FSSessionRepo.
Dry-run on real data: 19 runs -> 3 sessions + 21 turns, 0 failures.
