Records stored only a run's token/turn totals, so an arm's turn cost —
the dominant driver of cache-read tokens — could not be diagnosed from
the store. Retain the ordered transcript of tool invocations (the exact
shell commands, MCP calls, and built-in tools the run made) on every
scored record, absent only for a hung run that produced no transcript.
The canonical TranscriptEntry shape lives on the record (result.ts); the
isolation audit's ToolUse now aliases it so the persisted and audited
shapes cannot drift.
Thread every benchmark layer to run one (arm, task, trial) cell end to
end: provision and seed a throwaway repository, run the agent under the
active arm bounded by a turn cap and a wall-clock backstop, audit the
transcript, capture and score the post-run state, append the sample, and
delete the repository.
- runner.ts: runCell orchestration behind the BenchHost and AgentDriver
seams, so the flow is unit-tested with fakes while the live wiring is
validated by a smoke run; turn-cap and wall-clock failures are tagged
confused-versus-hung, and a leaked transcript is flagged invalid.
- audit.ts: the post-run transcript audit plus the shared
foreignToolReason predicate both isolation enforcement points consume.
- task.ts: the runnable BenchTask wrapper and one sample single-mutation
task exercising the full path.
- snapshot.ts: captureRepoState, the seed's read-back counterpart, in the
RepoState shape the checker diffs against.
- host.ts / sdk-driver.ts: the live BenchHost and the Claude Agent SDK
driver (an optional peer, loaded via dynamic import) for real runs.
- runner.smoke.test.ts: the live tracer-bullet tier, skipping cleanly
when no host or SDK is configured.
