# SQL protocol knowledge base for 1C configuration storage

This directory is the durable, evidence-first record for the 1C SQL adapter.
It complements [the general format specification](../1c-sql-format-spec.md).
Do not put all observations into one chronological note: add a fact to the
document for its layer, object type, codec, operation, or experiment.

## Non-negotiable runtime rule

The adapter works **only through SQL**. It may decode and encode only what was
observed in the target database and proven by round-trip checks. It must never
invent a metadata object, physical path, BSL fragment, form element, join,
codec, or cryptographic value. Unknown or ambiguous work returns an explicit
unsupported/protocol-incomplete result.

The Configurator remains a human-operated consumer of the saved-state overlay.
The adapter does not start it, automate it, or claim to change its in-memory
state.

## Maintenance rule

After every material protocol investigation, record all three outcomes:

1. proven direction and the exact evidence;
2. failed direction and why it failed;
3. remaining unknowns and the next safe experiment.

Keep raw payloads and credentials out of git. Reference private learning
artifacts by opaque ID or SHA-1 only.
