ADR 0005: Canonical financial naming#

Context#

Source abbreviations are unstable and often hide financial meaning or units.

Expose versioned English snake_case names with explicit price, count, volume, value, date, timestamp, identifier, currency, and unit semantics.

Preserving source names and publishing aliases were considered.

Downstream data is provider-independent; version 1.0 requires user code changes.

Legacy aliases, silent float coercion, and null-to-zero conversion are rejected.

Semantic changes require a canonical schema version and data-dictionary update.
