Improve SDP backup/recovery, Maintenance, logging and cloud operation.
Add owned checkpoint locks, recovery-aware retention, preserved database switches,
bounded cleanup and coordinated AWS/Azure snapshots. Fix service-user password
initialization, edge staging, standby promotion state parsing, proxy cache setup,
typed depot verification and historical-server configuration/error handling.
Remove unused OTP programs; keep Windows removed, server.locks cleanup and the
journal-count condition unchanged. Add no global shell strict modes.
Update operational documentation and add reproducible mkdirs.sh/mkdirs.cfg
container assurance. Validate Ubuntu 26.04 and UBI 8.10/9.8/10.2 across both Python
runtimes: 44 stages; 428 offline tests per runtime/OS, zero offline skips;
19 deployed-archive comparisons per combination. Three six-node topology runs
pass all 30 recovery/failure scenarios. P4D 2023.1 through 2026.1 on UBI 8/9
pass all 14 cells and 98 scenarios. Static, documentation and provenance checks
pass. Containers do not certify every fleet kernel, patch build or integration.
