    "Replaced the live vibe-coding hourly row with coding-agent-requests-intensive, an explicitly qualified per-human-request activity.",
    "Adopted 150 Wh per request from 170,000 Wh divided by 1,138 typed human prompts in Hausfather's modeled intensive Claude Code workload; automatic model and subagent calls represented in the logs remain inside that denominator.",
    "Applied the existing inferred AI water scenario to the new row: 150 mL direct and 900 mL broader water per request, with broader water including direct water.",
    "Removed the historical 30 Wh laptop increment and coding-device preset selection; omitted device, network, external tool execution, training, and embodied energy remain unquantified.",
    "Changed the Gen Z vibe-coder starter from one coding-agent hour to 15 illustrative agentic tasks, counted as 15 human coding-agent requests without claiming verified completed outcomes, while preserving all other quantities and device selections.",
    "Added optional activity displayQualifier and shortLabel fields, the requests unit, the operational-coding-request boundary, and an optional display_qualifier CSV column.",
    "Preserved Couch as historical provenance and credited Ippolito separately for the discovery trail and action/depth framework; neither supplies the adopted 150 Wh coefficient.",
    "Preserved all immutable v0.1.0 through v0.4.1 exports and release history."
