#!/usr/bin/env bash
# sync-wallet-fixture.sh — copy the wallet fixture to the canonical runtime slot.
#
# Purpose:
#   After a successful overlay install, ensures the canonical wallet fixture is
#   present in the checkout's runtime dir. Non-zero exit is informational (no
#   fixture source found); the install already succeeded, so the overlay is fresh.
#
# Inputs (flags / env):
#   --target <checkout>     (default $PWD)
#   --slot-id <id>          (env FARMSLOT_SLOT_ID, SLOT_ID — farmslot sync source)
#   --cdp-port <port>       (env CDP_PORT — extension fixture seeding port)
#
# Outputs:
#   Copies wallet-fixture.json to <target>/<RECIPE_RUNTIME_DIR>/wallet-fixture.json
#   when a source is found. Exit 0 always (non-zero only when no source found;
#   callers treat this as informational).
#
# OS-glue only: file copy and farmslot delegation; decision logic lives in
# src/commands/fixtures.ts.
