Struct RunRow 

pub struct RunRow {
    pub session_id: String,
    pub started_at: DateTime<Utc>,
    pub provider: String,
    pub model: String,
    pub title: Option<String>,
    pub workspace: PathBuf,
    pub run: u32,
    pub stats: RunStats,
}

One finished run, with enough of its session to be identifiable.

Fields

session_id: String

started_at: DateTime<Utc>

When the session started. A resumed session’s later runs share it; the transcript records no per-run stamp, and inventing one from file mtime would be a guess dressed as a measurement.

provider: String

model: String

title: Option<String>

workspace: PathBuf

Where the session was rooted.

Recorded in every transcript header since the store existed, and read into the corpus only on 2026-08-31. It is what separates populations this loop had been pooling: a morning-briefing run out of ~/.mecha/work/morning, a front-door run, a smoke test in /tmp and a feature test in the source checkout have different normal behaviour, and a harness change measured across the mixture is measured against an average of four different jobs. On the day it was added the store held 389 runs across eight workspaces, only 12% of them in the mecha checkout.

Retroactive on purpose, and it is why no new marker was invented: the field was already on disk in all 490 sessions, so the separation cost nothing and covers all of history rather than starting from now.

run: u32

Which run within the session, 1-based. A resumed session has several.

stats: RunStats
