Module runtime_config 

Runtime configuration snapshot and small env parsing helpers.

This is intentionally a narrow data surface first: it makes effective FERRUM_* overrides visible in health and bench artifacts while the hot-path env reads are migrated to typed config structs.

Structs

RuntimeConfigEntry

One effective config value in a runtime snapshot.

RuntimeConfigSnapshot

Stable snapshot of non-default runtime configuration visible to the process.

Enums

EnvTriState

Tri-state env override used by paths that distinguish unset from forced off.

RuntimeConfigEffect

Impact classes used by config snapshots and artifact diffs.

RuntimeConfigSource

Source of an effective config value.

Functions

active_runtime_snapshot

The installed runtime snapshot, or an empty snapshot when none was installed (unit tests that do not exercise runtime knobs see defaults).

install_runtime_snapshot

Install the process-wide runtime snapshot resolved at the composition root.
