no-mistakes(document): Docs already covered the persona refactor thoroughly; fixed one inaccuracy: ABSENT vs UNREADABLE persona states were conflated in AGENTS.md and docs/configuration.md omitted the UNREADABLE case entirely, so both now describe it as its own distinct repair failure matching bin/fm-session-start.sh's actual behavior.

 Swap the voice by editing tracked `persona.md` directly, or by dropping a local, gitignored `config/persona.md` in this home; when present, the local file fully replaces the tracked default rather than merging with it, mirroring `config/crew-harness`'s override pattern.
 `bin/fm-session-start.sh` resolves and prints the active persona's full contents unconditionally, every session, labeled by source (tracked default vs local override), so the voice is always in force with no per-reply trigger to load it.
 An absent persona (both tracked `persona.md` and `config/persona.md` missing) is reported distinctly from an `ABSENT` context-digest file: unlike `data/captain.md` or `data/learnings.md`, there is no built-in-defaults fallback, so it signals the tracked file needs repair.
