openclaw - 💡(How to fix) Fix doctor --fix strips renamed config keys and disables the plugin instead of migrating

Severity: medium — silent loss of operator configuration during an upgrade repair.

Version: 2026.5.18.

Summary: After upgrading, a config had plugins.entries.codex.config.codexDynamicToolsProfile (valid in the prior version). 2026.5.18 renamed this key to codexDynamicToolsLoading (enum searchable|direct). openclaw doctor --fix resolved the "additional properties" validation error by deleting the key and setting the plugin enabled: false — rather than migrating the renamed key. This silently disabled the codex plugin, which in turn unregistered the codex agent harness that scheduled jobs depend on (MissingAgentHarnessError: Requested agent harness "codex" is not registered).

Reproduction:

1. On a pre-2026.5.18 config with codex.config.codexDynamicToolsProfile set, upgrade to 2026.5.18.
2. Run openclaw doctor --fix.
3. Observe codex.config stripped and codex.enabled set to false.

Expected: doctor --fix should migrate renamed keys where the mapping is known (codexDynamicToolsProfile → codexDynamicToolsLoading), or at minimum report the removal and preserve enabled rather than silently disabling a plugin other components depend on.

Workaround: re-enable the plugin and set codexDynamicToolsLoading: searchable.
