1//! # orbok-workers
2//!
3//! Synchronous pipeline workers for M5/M6: pull queued jobs from the
4//! catalog and execute them in dependency order.
5//!
6//! **Worker chain (per file):**
7//! ```text
8//! [Scan queues Extract]
9//!   → ExtractionWorker  (extract + cache + record)
10//!   → ChunkAndIndexWorker (chunk + FTS index + chunk_locations)
11//! ```
12//!
13//! Failure isolation: one file's failure never stops the whole run
14//! (RFC-004 §16, RFC-005 §13). Workers update the relevant catalog
15//! records with the error category.
