run 2026-10-07 02:00 UTC against staging · 12 failure modes · halted by a stop condition
disk fill 95% crossed its stop condition (write errors above 5% on ledger-db); the run halted there and the modes after it were not reached

Suggested remediation
02 · Memory Pressure 90% degraded
- Set memory limits with headroom over the working set, and shed load before the limit. — from: observed “swap thrash”
03 · Disk Fill 95% failed
- Alert on volume usage well before it is full, and on write errors, not only on crashes. — from: observed “write errors”
- Cap what fills the volume — log rotation, retention limits, a quota — so usage falls back without a person. — from: no recovery inside the injection window
record: evidence/ledger-staging/2026-10-07. What was injected, what was observed and what broke, dated. This run has no sealed record. Every failed or degraded row links to its written report — impact and remediation — which the record carries too.
