Three tasks. July 2, 2026 weighted to 10.3x leverage across 32.0 human-equivalent hours in 187 Claude-minutes. Supervisory leverage closed at 61.9x. A smaller, infrastructure-heavy day: a structured-output benchmark across several candidate models that surfaced three live bugs, overnight kernel-panic incident recovery, and synthesis-pipeline parallelization and decoupling.

Task Log
| # | Task | Human Est. | Claude | Sup. | Factor | Sup. Factor |
|---|---|---|---|---|---|---|
| 1 | Built and ran a structured-output benchmark across several candidate models (via an internal inference service); found live bugs in inference-auth, forced tool-choice temperature handling, and a cost-accounting cache path | 10.0h | 30m | 8m | 20.0x | 75.0x |
| 2 | Diagnosed an overnight kernel panic (watchdog timeout from out-of-memory conditions during parallel synthesis) and safely restarted an interrupted 14-package academic-curriculum synthesis batch: offloaded models to shared NLI/embedding servers, fixed runtime-mode and directory-path configuration, cleaned up orphaned jobs, and added a serial orchestrator with memory watchdog, checkpoint/resume, and archive backup | 8.0h | 47m | 3m | 10.2x | 160.0x |
| 3 | Synthesis-pipeline work: dual-run six-way parallelization, decoupled the job-orchestration service from the inference engine (directory-path config fix across 11 scripts, plus test and completeness-gate fixes), and drafted an isolation-architecture plan for the platform | 14.0h | 110m | 20m | 7.6x | 42.0x |

Analysis
The day's leverage distribution matters more than the headline figure. The 20.0x ceiling came from Built and ran a structured-output benchmark across several candidate models (via an internal inference service); found live bugs in inference-auth, forced...; the 7.6x floor was Synthesis-pipeline work: dual-run six-way parallelization, decoupled the job-orchestration service from the inference engine (directory-path config fix across.... Tasks at the top of the distribution share a shape: tightly-scoped specifications, clear success criteria, and minimal integration ambiguity. The AI doesn't need to discover anything new; it executes against an explicit target.
Tasks at the bottom run differently. They're either bounded by review-heavy work where every step gets verified, or they involve ambiguity that demands several rounds of trial and adjustment. The factor is real and informative, not a failure mode.
The lower task count and the weight of debugging and incident recovery pulled the day's leverage down; recovery and pipeline decoupling are iterative and verification-heavy, the classic lower-leverage shape.
The supervisory leverage figure (61.9x today) tracks something orthogonal to wall-clock leverage. It's the ratio of human-equivalent output to human prompt-writing time. It stays high even on lower-leverage days because supervisory minutes scale with task count, not with the human-hour estimate; a 20-minute task and a 4-hour task can both be specified in two minutes of human prompt-writing.
Across the 3 tasks, the day produced roughly 0.8 weeks of senior-engineer-equivalent throughput in 3.1 hours of model wall-clock. That ratio is the practical answer to the question of how much output a single operator can move per day when the model handles the execution and the operator handles the direction.
