LOTUS_E2EE_INVESTIGATION.md: per-KE capture runbook (console signatures, synapse
log greps + SQL against the documented LXC deployment, the KE-1⇒KE-2 causality
decision tree, ranked remediations incl. what a crypto-store reset wipes; SDK
finding: stable 41.6.0 has no OTK fix over our RC pin). Client: capture-only
console ring buffer (cryptoDiagLog, KE-signature-matched, max 200) + a Crypto
Diagnostics card in Developer Tools with a download-report button. ClientRoot
installs the capture hook at module load and mounts useSessionSync (cross-tab
sessions, prior commit).
