Struct FileChangedPayload 

pub struct FileChangedPayload {
    pub session_id: String,
    pub transcript_path: String,
    pub cwd: String,
    pub prompt_id: Option<String>,
    pub hook_event_name: String,
    pub file_path: String,
    pub event: String,
}

The payload captured from Claude Code 2.1.223’s FileChanged event.

Unlike the MCP input DTOs, this deliberately does NOT deny_unknown_fields: those parse untrusted client input, this parses a platform payload that gains fields between Claude Code releases. Rejecting one would stop the freshness updates with no signal.

Fields

session_id: String

transcript_path: String

cwd: String

prompt_id: Option<String>

Absent when the watcher fires outside a prompt turn.

hook_event_name: String

file_path: String

Absolute, and echoed back in the exact spelling mati handed to watchPaths — Claude Code does not canonicalize it. Resolve symlinks on both sides before comparing it to a repo root.

event: String

chokidar event: add, change, or unlink.

Implementations

impl FileChangedPayload

pub fn drives_reparse(&self) -> bool

Whether this event should drive a reparse.

add and change only. unlink is deliberately ignored: it would set the FileDeleted staleness signal and pin the record at the Tombstone tier, and apply_reparse_staleness only saturates upward — so a save that lands as delete-then-create would suppress that file’s context injection for good. Real deletions are still caught by mati init and mati repair, and the read gate stats the file live before honouring the signal (hooks::decide::evaluate).
