Anticipate failure modes

For each severe vectors and similarity failure on the internal FAQ semantic search, define stop condition, safe state, owner, and lasting prevention. Rollback only works if prior prompts, indexes, and models remain available. “Send to a human” needs queue capacity and context—not just a button name.

Run one tabletop on the internal FAQ semantic search for vectors and similarity: inject a defect, verify detection, contain, recover, and keep the blameless trace.

After the tabletop, store the injected vectors and similarity defect for the internal FAQ semantic search as a regression fixture. If the same failure later reaches users silently, your detection story was aspirational. Detection without a fixture tends to rot for vectors and similarity.

Also pin one numeric memory from this vectors and similarity chapter: cos(a,b)=(a·b)/(||a|| ||b||)=(1×2+2×4)/(√5×√20)=10/10=1 That number is not decoration; it is a template for how claims about vectors and similarity on the internal FAQ semantic search should look in design docs.

People confuse vectors and similarity with neighboring buzzwords when debugging the internal FAQ semantic search. Before changing prompts, ask whether the broken stage was evidence gathering, the vectors and similarity judgment itself, validation, or the product action. Fixing the wrong stage creates folklore (“we tried vectors and similarity and it failed”) that blocks the next team on the internal FAQ semantic search.

Write a five-line artifact for this page: goal, inputs, check, owner, stop rule. Invent one fluent failure that the check would catch. Keep details specific to vectors and similarity rather than generic AI advice.
