regression CASCADE: 13 jobs newly red in 6f085e162..e5cd18e4b (1 commits) — auto-filed by twatch
- Type: regression cascade (auto-filed by Track T watcher, host borg). Untriaged. 13 jobs went red in ONE sweep — treat as ONE root cause until triage proves otherwise; do NOT fan out per-job tickets.
- Found: 2026-09-13T14:57:05Z
- Root-cause suspects in the red set: none of the known root jobs (
fpc-bootstrap,selfhost-fixedpoint). That is the ONLY heuristic applied here — it does not imply a harness event, and nothing in this filing looked at the build, the box or the range. See the Range section below for commits worth checking.
Range
bad e5cd18e4b220, last good 6f085e16261e, 1 commit(s) in range (1 of them buildable). No idle bisect will happen — the watcher skips cascades deliberately (one synthetic key matches no job), so this range is narrowed by hand or not at all.
Buildable commits in the range, newest first:
e5cd18e4b220fix(N): a dynamic receiver's attribute no longer binds to another class's offset
Repro (start with a suspect, or any listed job)
tools/testmgr.py --tier full --job '<job>' at e5cd18e4b220306c1b9d1e3c9308371f7969a533
(The sha above is the right one to REPRODUCE at — the jobs really are red there — even when the Range section says it cannot be the CAUSE. Reproducing and blaming are different questions and this line answers the first.)
Newly red jobs
Each job's own recorded failure REASON is printed under its name. When the reasons and the Range section disagree, the reasons win. The range is computed from what CHANGED, not from what the job can SEE — a missing guest loader, an absent dev package or a job that has never once passed on this box all produce a red that no commit in the range caused.

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
- 2026-09-14 — auto-closed by the borg watcher:
cascade@e5cd18e4b220passes at 4e3414d4d18e (tier full); it was red at e5cd18e4b220. Reopening is by a fresh NEW-RED stub, since a second red is a second finding with its own range.
