# issue 26811: does Codex replace a symlinked shadow config.toml? codex-cli 0.163.0, Linux x64
# shadow/config.toml -> shared/config.toml, CODEX_HOME=shadow
codex mcp add demo -- echo hi                    -> "Added global MCP server 'demo'."; shadow/config.toml still a symlink; edit landed in shared/config.toml
codex features enable agent_message_board        -> "Enabled feature ..."; shadow/config.toml still a symlink
app-server config/value/write (model=gpt-5.1)    -> status ok; shadow/config.toml still a symlink; edit landed in shared/config.toml
app-server config/batchWrite (effort=high)       -> status ok; shadow/config.toml still a symlink; edit landed in shared/config.toml
Result: the config.toml symptom did not reproduce on this Codex version.
