# sf-from-source — run SF directly from this source checkout via bun.
#
# Purpose: every local commit in this repo (e.g. the #4251 fix) is live
# immediately without reinstalling the bun-packaged sf-run. Subagents can
# spawn sf by pointing SF_BIN_PATH at this script instead of dist/loader.js.
#
# Contract:
#   - Executable shim spawn() / exec() can launch directly.
#   - Exports SF_BIN_PATH before handing off to loader.ts so loader.ts's
#     `SF_BIN_PATH ||= process.argv[1]` branch preserves the shim path
#     instead of clobbering it with the .ts loader path (which is not
#     directly executable by child_process.spawn).
#
# Requirements: bun on PATH, node_modules populated (`bun install` once).
