Prediction hash

Fixes a prediction before the page it belongs to goes live. The file is plain text with a date in its name; its sha256 goes into predictions/HASHES.txt; both land in one commit. From then on the hash shows whether the text changed. The gate check aieo.prediction-hashes fails a deploy when a listed file is missing or changed, or when a prediction file is not listed.

Inputs

• The page the prediction belongs to, and its URL.
• The prediction: what is measured, how (engines, queries, runs, what counts as a hit), the reading date, and the result that refutes it.

Steps

1. Copy the templates without overwriting:

   mkdir -p predictions
   cp -n "${CLAUDE_PLUGIN_ROOT}/templates/predictions/HASHES.txt" "${CLAUDE_PLUGIN_ROOT}/templates/predictions/README.md" predictions/
