Two new things working together:
1. Migration 0005 adds chapters.body_md_tts (nullable). Narrate path
prefers it over body_md when present — that's the annotated-for-
audiobook variant. Falls back to body_md if not set.
2. New Forge::narrate_prep pass: author (or House) annotates prose
with [breath] / [pause:Xs] / [scene] beat markers AND occasional
humanizing narrator stumbles (em-dash repetition, self-correction,
hesitation — sparingly, 1-3 per chapter). Apart from stumbles, the
prose is verbatim. Author voice threads through.
3. New CLI: 'skald prepare-narration --chapter <uuid> [--author slug]
[--overwrite]'. Records as generation_runs row kind=narrate_prep.
4. skald narrate now routes by voice.source — kokoro_* voices hit
KOKORO_URL (Apache 2.0 stack, audiobook-tuned with the v0.2 render-
and-stitch server), everything else hits F5_TTS_URL (voice-cloning
path). Voice DB row carries source as the dispatch key.
Why no new tag for narrator stumbles: em-dash repetition and self-
correction are just prose patterns Kokoro reads correctly because of
its punctuation cues. No new server-side machinery.
