+# `__configinfo`: file map and service atom
+
+## Proven map
+
+The decoded `E__configinfo` text contains logical file-name pairs:
+
+```text
+"<object-guid>.0",<base64 of 20-byte SHA-1>
+```
+
+The Base64 value is the SHA-1 of the complete raw `BinaryData` stream for that
+logical file. Updating a module without replacing this map value produces the
+Configurator error “Ошибка хеш-версии файла конфигурации”.
+
+The map rewrite is deterministic and losslessly round-trip proven for the
+studied extension form module.
+
+## Service atom: current status
+
+The root block also contains three observed binary atoms: two 48-byte values
+and a 32-byte value. The 32-byte value changed across manual saves, including
+when the module bytes returned exactly to a previous SHA-1. A random mutation
+of its variable part triggered a platform licensing/crypto error.
+
+Therefore:
+
+- preserve all service atoms byte-for-byte during the proven incremental
+  protocol;
+- do not synthesise, randomise, zero, or “recalculate” them;
+- do not claim their reverse codec is known;
+- record new observations in an experiment file before changing this rule.
+
+The `test2` map-update experiment activated successfully while preserving the
+existing service atom. This is activation evidence for preservation, not for
+generation.
