Failed to update setting: invalid inline diff mode '{value}'

Error message

Failed to update setting: invalid inline diff mode '{value}'. Expected: full, summary, or off.

What it means

Settings update validation for the inline-diff key (inline_diffs/inline_diff/diffs): the normalized value is neither full, summary, nor off. Controls how diffs render in the transcript; invalid values are rejected rather than defaulted.
