Candidate IDs, +probabilities, resolved models, and request counts were checked for every record. +All three 80-candidate queries made exactly two batched calls. Live vector, FTS, +hybrid, empty-FTS, and multivector integration checks also passed in both modes. +No correctness fixes were needed. + +The subsequent batch-ordering simplification passed all 124 automated tests and +a fresh four-query live check (original query indices 0, 1, 2, and 8; 292 candidate +pairs). Unbatched/batched calls were 292/8, including exactly two calls for the +80-candidate case.

Counts above exclude other +queries completed before stopping. The high unbatched p95 is retained as observed; +it is not attributed to a specific cause. A complete 2,000-query paired benchmark +is still needed before making a general performance or quality claim. Exact values +and configuration are in [the subset test report](typesafe_subset_test.json). + +The historical GooAQ results motivated this patch: the earlier custom adapter +reported 186 ms median / 387 ms p95; native unbatched scoring at concurrency 32 +reported 805 ms / 1,193 ms for 2,000 queries and 136,586 candidate pairs using +`jev-1.13.0`.

See the +[research results](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/results/README.md) +and [earlier adapter](https://github.com/lancedb/research/blob/412a522/reranking/jev_reranker.py). + +## Run the paired benchmark + +Use the exact `candidates.json` from the research benchmark cache. It is a JSON +array of records with `query`, expected `answer`, ordered `vector` and `fts` ID +lists, and a `documents` mapping from string IDs to text. Distinct IDs may have +identical text. To prepare candidates without scoring models, use the research +branch's [benchmark](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/compare_jev.py) +with `--models none`; its default corpus and query counts reproduce the protocol. + +After bootstrapping this checkout's Python development environment, run from +`python/` (set `TYPESAFE_API_KEY` or pass `--api-key-file`): + +```sh +uv run --extra tests --with typesafe-sdk==0.7.1 benchmarks/bench_typesafe.py \ + --candidates /path/to/research/reranking/.benchmark-cache/candidates.json \ + --model jev-1.13.0 --max-concurrency 32 \ + --cache /tmp/typesafe-batching-fresh \ + --output /tmp/typesafe-batching-results.json +``` + +Both modes use the same installed SDK, model, prompt, candidates, and concurrency. +They score each query's candidate union once, alternating which mode runs first. +Timings include native reranking and SDK retries, exclude retrieval, and report +median/p95 milliseconds.

Persistent OAuth token cache and session lifecycle APIs. +//! +//! By default, OAuth sessions are kept in process memory only (see +//! [`OAuthHeaderProvider`](crate::remote::OAuthHeaderProvider)). Short-lived +//! processes such as CLI tools, notebooks, or scripts would otherwise have to +//! run a full interactive browser or device flow on every start. Configuring +//! [`TokenCacheOptions`] on an [`OAuthConfig`](crate::remote::OAuthConfig) opts +//! in to an explicit, hardened, on-disk cache that stores only the refresh +//! token plus non-secret metadata, so a second process can silently refresh +//! instead of re-prompting. +//! +//! Security properties: +//! +//! - Opt-in only; callers that do not configure a cache stay memory-only. +//! - Only refresh tokens are persisted. Access tokens never touch disk, so +//! there are no local expiry decisions to get wrong when clocks move. +//! - No client secret is ever stored. +//! - The cache directory is private (`0700`) and each record is `0600`, +//! owner-checked, and symlink-rejected on Unix; records are replaced +//! atomically via `rename` so a crash can never leave a torn file. +//! - Cache filenames are SHA-256 hashes of the canonical issuer, client, +//! scope, resource, audience, flow, and client-auth identity. No secret appears +//! in a filename. +//! - Refresh-token rotation is serialized across processes with a per-key +//! advisory file lock (`flock` on Unix, `LockFileEx` on Windows). The +//! operating system releases these locks when a process dies, so a crash +//! cannot leave a stale lock behind. +//! +//! Use [`OAuthSession`] to explicitly `login`, inspect `status`, or `logout` +//! without issuing a database request. +//! +//! # Example +//! +//! ``` +//! use lancedb::remote::{OAuthConfig, OAuthFlow, TokenCacheOptions}; +//! +//! # async fn example() -> Result<(), Box> { +//! let config = OAuthConfig { +//! issuer_url: "https://issuer.example.com".to_string(), +//! client_id: "my-app".to_string(), +//! client_secret: None, +//! scopes: vec!["openid".to_string()], +//! flow: OAuthFlow::DeviceCode, +//! client_auth_method: None, +//! refresh_buffer_secs: None, +//! resource: Some("https://api.example.com".to_string()), +//! audience: None, +//! token_cache: Some( +//!
