What's this about?
SELF-INDEX detects retrieval failures, revises only implicated document keys and validates the change. A query simulator also proposes information needs not present in the optimisation set.
What exactly is an index key?
It is a representation that makes a document discoverable for certain queries. Changing keys can surface hidden knowledge, but synthetic queries may optimise for imagined rather than real demand.

- Static indexes age as user needs change.
- Selective revision may be cheaper than rebuilding everything.
- Autonomous optimisation needs safeguards against relevance regressions.
