-- Placeholder migration for adding a similarity_cache table
-- Decision: Keep SQL commented out so CI does not accidentally modify databases.

/*
-- Example (commented out):
CREATE TABLE similarity_cache (
    id SERIAL PRIMARY KEY,
    key TEXT NOT NULL,
    vector FLOAT8[] NOT NULL,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT now()
);
*/

-- No executable SQL in this file. Intentionally left as a safe no-op.
