# Known dead ends and prohibited shortcuts

## Do not repeat

- Do not write only a module `.0` row: `__configinfo` then references stale
  bytes and activation fails.
- Do not use random, zeroed, copied-from-unrelated, or guessed HashVersion
  service atoms. A controlled random test produced a licensing/crypto error.
- Do not write `Config` or `ConfigCAS` directly, even in tests.
- Do not use a suffix such as `.0` as proof of “object module”.
- Do not infer an object name from a GUI tree label, table suffix, or an
  approximate Russian name.
- Do not overwrite all saved-state rows when adding a delta: preserve user
  work in other objects and every map entry.
- Do not treat an open Configurator screen as SQL evidence.

## Open questions

- The generation algorithm and ownership of the 32-byte `__configinfo`
  service atom are unknown. Preservation is proven for the studied flow;
  generation is not.
- Multi-part storage streams need a dedicated row-layout codec.
- The extension protocol must be reproduced on another object class and a
  second platform build before being declared generally supported.
- Configurator’s in-memory dirty-state implementation is inferred from
  behaviour, not decoded from platform source. Only the reload guidance is
  operationally relied upon.
