Behavior fixes surfaced by the prompt-guide validation campaign (Tier 1+2
of the upstream bug list; Tier 3 tracked in #2107). Split out from the
doc-only updates, which follow in a separate PR.
- BGM level: default bed volume under narration was 0.8 linear (~-2 dB,
~16 dB too hot vs voice). Now 0.12 (~-18 dB) via shared
bgmDefaultVolume() in media-use bgm.mjs + assemble-index fallbacks in
faceless-explainer / pr-to-video / product-launch-video. Explicit
volume still wins; silent-film 0.9 and music-to-video unchanged.
Adds bgm.test.mjs (3 cases); bgm.md reference updated to match.
- Caption accent: semanticColors() ranked accents purely by chroma, so a
preserved status red (#dc2626) outranked the brand accent and captions
highlighted in error-red. Status-keyed colors now excluded via shared
STATUS_ROLE_KEY regex consumed by both tokens.mjs and build-frame.mjs
(all three skill copies kept in sync).
- Voice threading: workflow SKILL.md Step 3.1 blocks now instruct
choosing the narration voice from the user's ask and passing
--voice <id>; previously "a male voice" was silently ignored and the
default (Marcia/am_michael) always won.
- fetch-pr shipping version: MERGED PRs get best-effort shipped_version
+ version_source in pr.json (first release published at/after merge,
else default-branch package.json marked unreleased); ingest surfaces
it as a 'Shipped in:' brief line; story-design.md forbids inventing
versions when absent.
