Struct Store 

pub struct Store {
    pub keys: Vec<(String, i64)>,
    pub files: Vec<PathBuf>,
    pub had_error: bool,
}

One supported agent tool. An adapter knows where the tool keeps its session files on disk and how to parse one file into a Session.

Adding support for a new tool means implementing this trait in a new module and registering it in all(). PRs for new adapters are the main way this project grows. A store that holds many sessions in one place (e.g. a SQLite database) rather than one file per session. Returned by Adapter::store when the file-per-session model does not fit; the indexer then enumerates sessions from keys (re-parsing only changed ones) instead of discover/parse.

Fields

keys: Vec<(String, i64)>

(stable key, change-token) for every session, cheap to compute without a full parse. The change-token (e.g. the session’s updated-time in ms) drives incremental re-indexing; the key identifies the session for Adapter::parse_key. The key doubles as the session’s stored path.

files: Vec<PathBuf>

The backing files (the database), for scan size accounting.

had_error: bool

True if a backing store existed but could not be read this run (locked, half-written, permissions). The indexer then skips deletion reconciliation, so a transient read failure cannot archive the whole corpus off an incomplete key set.
