 *
 *                            off (default): no outcome feedback events are
 *                              captured and no hypothesis mining runs. Zero
 *                              behavior change.
 *                            shadow: capture one idempotent append-only
 *                              feedback event per explicit owner action, mine
 *                              neutral trade-off hypotheses for the exact
 *                              recipient + intent + fingerprint, and emit
 *                              aggregate telemetry only. No question, ranking,
 *                              intent, premise, memory, newborn-stamp, or push
 *                              writes.
 *                            on: reserved for a later phase (IND-438) that
 *                              turns a grounded hypothesis into a user-facing
 *                              question. This slice treats "on" exactly like
 *                              "shadow" for capture + mining; it never emits
 *                              questions.
 *
 * All reads go through this module — do not read this variable via
 * `process.env` elsewhere. Values are read on every call (no caching) so tests
 * and long-lived processes observe changes.
