Reference pages for Search cassette, synced at build time from
[papercomputeco/search-cassette](https://github.com/papercomputeco/search-cassette). Each page is owned by
that repo, so a behavior change and its documentation land in the same
pull request there.

- [Search cassette](/docs/search/introduction/) — Semantic span search over the tapes read model, with the embedding pass that keeps it current.
- [API reference](/docs/search/api/) — The span search endpoint, the MCP tool over the same operation, the result shape, and status codes.
- [Embedding](/docs/search/embedding/) — The embed pass that keeps the span projection searchable — how it selects work, how it handles failure, and the metrics it exposes.
- [Deploying](/docs/search/deploying/) — The image, its configuration, the embedding providers it supports, and the database objects a deployment must provision.
- [Development](/docs/search/development/) — Build and test from a checkout, how the module relates to tapes, and what the test suite pins.
