//! Zoo Code detection: document fingerprints for rewritten ui_messages.json arrays.

//!

//! ui_messages.json has no version field. Fixed source f780647 taskMessages.ts

//! parses the whole file as a JSON array. Use document-level format

//! [`super::versions::ZOO_FORMAT_VERSION`], without unknown-version dispatch.

//!

//! Detection rules (V17 rejects unrecognized shapes):

//! - The first 64 KiB, after UTF-8 BOM removal, must start with a JSON array.

//! - Missing say/type fingerprint is UnknownFormat.

//! - Empty content is Pending and is probed again next round.

//! - A matching fingerprint is Supported with the registered document format;

//!   basis is KnownVersion. Scanning checks the complete documented ask/say set,

//!   rejecting undocumented kinds and skipping known nonusage messages.

/// Detection window: first 64 KiB, without parsing the entire file.

/// Detect one task ui_messages.json file.

/// A matching fingerprint selects the fixed document format with KnownVersion.

// Transient read failure (lock/timeout/disappearance) is Pending for the next probe.

// Fingerprint: say/type markers; consolidateTokenUsage/consolidateApiRequests

// consume type="say" messages.
