Full-harness benchmark — campaign analysis

Real agents.py up Builder/Adversary loop pair + watchdog through the 3-phase calculator to SEQUENCE-COMPLETE. Both loops on Sonnet. Tokens summed from each loop's session transcript; commits = work-repo commit count; LOC = non-blank calc/*.py lines (code + tests). 30 successful runs of 33 total.

Efficiency ratios — min / median / max (successful runs)

tokens/sec excludes runs flagged LIMIT (a usage-limit pause inflates duration without adding tokens, so it would understate the true rate); tokens/LOC and tokens/commit are unaffected and include all successful runs.

Stats over successful runs. LIMIT = the run hit a usage-limit pause (duration/tok-sec distorted, token total fine). Repos kept under the run root for analysis.
