The SHA-256 integrity check introduced in migration 0007 blocks saves
when a character's savedata blob is imported from another server instance,
because the stored hash in the target DB no longer matches the new blob.
Adding DisableSaveIntegrityCheck (default: false) lets server operators
bypass the check to unblock cross-server save transfers. A warning is
logged each time the check is skipped so the flag's use is auditable.
Documents the per-character SQL alternative in CHANGELOG:
UPDATE characters SET savedata_hash = NULL WHERE id = <id>
Closes#183.
Only the database password is truly mandatory to get started, but
config.example.json was 267 lines with 90+ options. Newcomers faced a
wall of settings with no indication of what matters.
Add registerDefaults() with all sane defaults via Viper so a minimal
config (just DB credentials) produces a fully working server. Gameplay
multipliers default to 1.0 instead of Go's zero value 0.0, which
previously zeroed out all quest rewards for minimal configs. Uses
dot-notation defaults for GameplayOptions/DebugOptions so users can
override individual fields without losing other defaults.
- Shrink config.example.json from 267 to 10 lines
- Rename full original to config.reference.json as documentation
- Simplify wizard buildDefaultConfig() from ~220 to ~12 lines
- Fix latent bug: SaveDumps default used wrong key DevModeOptions
- Add tests: minimal config, backward compat, single-field override
- Update release workflow, README, CONTRIBUTING, docker/README
