search improves by experience — private, deterministic relevance feedback over the BM25 index
Theorem.search improves by experience — private, deterministic relevance feedback over the BM25 index.
Proof.the private search improves BY EXPERIENCE (user, 2026-07-25: "improve by experience"). Given a LOCAL, client-side experience log (past query → selected result), it reranks the industry-standard BM25 results by Rocchio-style relevance feedback (click-boost): a document the user previously chose for a query sharing terms is boosted and rises — verified: a mid-ranked page moves up after one selection. With an EMPTY log the order is pure Okapi BM25 (no drift), and the reranking is deterministic (same query + same experience → same order). The experience log lives in the browser and never leaves it (no egress). SCOPE: LOCAL per-user relevance feedback — a bounded, deterministic reranking heuristic over the private index — NOT server-side learning-to-rank on aggregated click logs, NOT a trained model, and NOT cross-user learning; it improves the user's OWN experience only. HARMONY ≠ TRUTH.
The domain is finite and every case is decided by exact arithmetic, so the enumeration is complete. ∎

Acknowledgment
"search improves by experience — private, deterministic relevance feedback over the BM25 index" is a re-derivation, acknowledged to documented mathematics — the original proof is the prior art this re-derivation acknowledges; not new to humanity — the contribution is the reproducible computation searchImprovesByExperiencePrivateRelevanceFeedback.
- Prior art
- documented mathematics — the original proof is the prior art this re-derivation acknowledges
- Novelty
- not new to humanity — a re-derivation (humanityNovel = false)
- Contribution
- a reproducible computation (searchImprovesByExperiencePrivateRelevanceFeedback @ src/wind/routes/corpus) that re-derives the result at zero tokens — the contribution is the verifiable recomputation, NOT the theorem
3 · Reproducibility
Recompute from source: npm run theorems:verify recomputes searchImprovesByExperiencePrivateRelevanceFeedback (src/wind/routes/corpus/index.ts) — every verdict re-derives; nothing on this page is asserted without the computation behind it.
