0004 — get_session transparent resolution

ADR-0004 — `get_session()` transparent local/SiS resolution

Status: accepted Date: 2026-05-31

Context

SiS apps run in Snowflake and use get_active_session(). Local dev requires a connections.toml-backed session. App code should not contain environment branches.

Decision

get_session(config?) resolves transparently: - SiS (default): get_active_session() - Local (PINKY_LOCAL=1): LocalSessionConfig backed by the connection in connections.toml

App code never changes — only the resolution layer switches via the env var. Local data is populated by pinky dump (from pinky-tools).

Consequences

Identical app code runs locally and in SiS. Local dev requires no mock session or fake Snowflake connection — a real connection via connections.toml is used.
