Pins, via new tests in hydrator.test.ts: - AC1: every hydrator CLI spawn passes { stdin: 'ignore', stderr: 'pipe' } - AC2: a per-step timeout aborts with the offending step named, demoting nothing - AC3: per-step timing logs (stable label + elapsed ms) via an injected clock - AC4: workspace-scoped pane list (--workspace ) and workspace id on the seam - AC5: per-tick candidate cap (default 50) with pane/dependency check preserved Adds hydrator.fixtures.ts: recording exec seam + 60-pane / 25-item worst-case fixtures for the implementation children. Red phase: 9 fail as expected (waiting for WL-0MUY1CXSV008F8TZ, WL-0MUY1CYCB003DTKO, WL-0MUY1CYV6008BQWX); 33 pass.
