# sf-from-source — run SF directly from this source checkout via node.
#
# Purpose: every local commit in this repo is live immediately without
# rebuilding dist/. Subagents can spawn sf by pointing SF_BIN_PATH at
# this script instead of dist/loader.js.
#
# Why node, not bun:
#   - bun doesn't ship node:sqlite (sf-db.ts falls back to filesystem-
#     derivation degraded mode under bun).
#   - bun's native-addon loader doesn't inherit the system library
#     search path under Nix (libz.so.1 not found for forge_engine.node).
#   - node 22.5+ has node:sqlite built-in; node 24 supports
#     --experimental-strip-types so .ts runs directly.
#   - The src/resources/extensions/sf/tests/resolve-ts.mjs loader hook
#     already handles .js → .ts import-specifier remapping for runtime
#     resolution.
#
# 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: node >= 22.5 on PATH (24+ recommended for strip-types),
# node_modules populated.
