Module sqlite 

SqliteRunTraceStore — SQLite-backed RunTraceStore using [rusqlite-isle], sharing the same database FILE as crate::store::run::SqliteRunStore (~/.mse/store/run.sqlite by default) in its own run_trace table. Sharing the file keeps “one Run’s persistence” a single artifact on disk; each store still owns its own confined Connection (its own AsyncIsle thread), so both connections set busy_timeout to ride out each other’s short write transactions.

Schema

CREATE TABLE IF NOT EXISTS run_trace (
  run_id       TEXT NOT NULL,
  seq          INTEGER NOT NULL,   -- per-run, 1-based, monotonic
  ts_ms        INTEGER NOT NULL,
  kind         TEXT NOT NULL,      -- namespaced open set
  step_ref     TEXT,
  attempt      INTEGER,
  payload_json TEXT NOT NULL,
  PRIMARY KEY (run_id, seq)
);

seq assignment and retention pruning run inside one transaction per append, so concurrent appenders to the same Run cannot collide on a seq or over-prune. Filtering (kind prefix / step_ref / attempt) is applied in Rust over the per-Run rows (bounded by the retention ceiling) — the query axes are too dynamic to be worth SQL-side predicates at this scale.
