Front door: request bodies capped at 1 MiB, headers within 5 s, body within 15 s, no response deadlines (SSE stays open). Validated live: 413 over the cap, stalled body cut at 15 s, signed ping and an SSE stream unaffected. svos-front-inventory also serves the previous release's hashed assets credential-free from that release's static dir, hash-checked. Backup check: reads the logs of vzdump tasks PVE records as OK and reports ERROR lines; an fs-freeze/thaw error is an application-consistency failure, new verdict DEGRADED (exit 4), wired into the alert wrapper. nh3-pve-2 added to the node and namespace lists (its job results were never read). The svos drill task is acknowledged by UPID; BACKUP_IGNORE_ACKS=1 counts it (positive control: exit 4).
svos-dev: the service worker fetches its hash-pinned INVENTORY with credentials omitted. Exactly those files plus /sw.js are now served before basic_auth (GET/HEAD, exact files). The list is generated from the release's sw.js by svos-front-inventory, which hash-checks each file and validates before reload. Gated static routes follow the web/README hosting contract: missing assets 404 instead of index.html, other document requests get index.html, everything else 404, unversioned files no-cache. acceptance-matrix.sh: 35/35 live; 16 FAIL against the previous config (positive control). git added to the nh3-svos playbook (kernel's remote check). Live backup drill: quiesced backup ~1-2 s outage; a refused freeze does NOT abort vzdump (unfrozen backup, job reported successful); both images restore-mounted read-only and verified.
