Experiment Ledger
This page is designed to grow weekly. It records source changes, protocol revisions, and future documented runs without overwriting older context.
"capabilities, safety evaluations"
2026-07-06
Initial protocol set published
Published the core method plus six experiment protocols: prompt sensitivity, long-context stress, tool-use boundaries, citation grounding, safety boundaries, and vision reading.
2026-07-06
Primary-source baseline recorded
Source map anchored to Anthropic model docs, context-window docs, evaluation guidance, citations, tool use, vision, prompt-injection guidance, transparency hub, system cards, and Responsible Scaling Policy.
Next update
Weekly extension slot
Add new rows when Anthropic changes model availability, context limits, safety/system-card summaries, citation behavior, tool versions, or when a protocol gains a documented run.
Ledger Rules
Add a row when an experiment protocol changes, a primary source changes, a model release changes the relevant behavior surface, or a protocol gains a documented result. Do not rewrite old entries to make them look current.
A result row must include the model ID, access surface, run date, fixture hash or fixture description, prompt version, source state, scorer, and raw-output location. If those fields are absent, the row should be labeled as a protocol note.
