regression CASCADE: 29 jobs newly red at 63d1d0de90d3 (auto-filed by twatch)

• Type: regression cascade (auto-filed by Track T watcher, host plexus). Untriaged. 29 jobs went red in ONE sweep — treat as ONE root cause until triage proves otherwise; do NOT fan out per-job tickets.
• Found: 2026-08-15T14:48:16Z
• Root-cause suspects in the red set: none of the known root jobs — likely a broken build or harness event

Repro (start with a suspect, or any listed job)

Cascade stub: one signal for one event. Track T agent (face 2) or the owning dev track triages the root; individual tickets only for whatever remains red after the root is fixed.

Log

• 2026-08-15 — auto-closed by the plexus watcher: cascade@63d1d0de90d3 passes at f68d60cebf50 (tier native); it was red at 63d1d0de90d3. Reopening is by a fresh NEW-RED stub, since a second red is a second finding with its own range.
