Outcome A, qualified. Not B and not C. It does not degrade: 5 of 5 restarts of 12.3 on an 11.6 datadir, readback passed every time, mariadb_upgrade_info unchanged, the entrypoint line never escalated past [Note]. It also never heals - the engine answers 'Major version upgrade detected from 11.6.2-MariaDB to 12.3.3-MariaDB. Check required!' on every start and will forever. The trade R-459 was expected to produce is not real. Converting properly SUCCEEDS across the multi-major jump, takes 7 seconds, backs up the system database unasked - and putting 11.6 back afterwards STILL starts and serves the data. So the operator is being handed a cheap correction, not a choice between a correct engine and a reversible one. The exit-code polarity was measured rather than read: 0 means the upgrade IS needed, 1 means it is not. Assuming either the flag name or the polarity would have inverted the headline. And run without credentials the same command returns a confident-looking FATAL ERROR that is an auth failure. R-464: after converting and going back, the entrypoint prints 'MariaDB upgrade not required' on a state the same engine calls an unsupported downgrade. The obvious cheap instrument for R-459 would have been to grep for that line, and it would have reported fine for the broken case. R-463: the PostgreSQL analogue, deliberately NOT measured here. 11 templates, 8 on postgres:16-alpine, register grep for pg_upgrade returns zero. The two engines fail in OPPOSITE directions - MariaDB skips quietly, Postgres refuses to start - so that one cannot hide; it presents as eight apps down at once. No template changed. Teardown all three layers, hub checked rather than asserted, local-lvm 30.53 percent before and after.
