# RULE R9: after a Ghidra save-shutdown, verify a recent edit actually persisted to disk.
# Read-only re-opens the SAVED project and checks the function/symbol name at <addr>.
# Run AFTER tools/ghidra_mcp_stop.sh (the server must be stopped — a read-only open needs
# the .rep lock free). Exit 0 = PASS (persisted), non-zero = FAIL / not verified.
#
# Example (after a phase's last edit was renaming 0x80018730 to LzssDecodeSector):
#   tools/ghidra_mcp_stop.sh && tools/ghidra_mcp_verify.sh 0x80018730 LzssDecodeSector
