v0.27.1

Fixed

• Autoplugs fire on manually-posted tweets. Marking a tweet sent now enrolls it into autoplug tracking (via a platform publication record), the same way API/scheduler posts are — so engagement-threshold autoplugs fire on manual posts, including quote tweets (which the X API can't post and so always go through mark-sent). Previously a manual post only wrote local frontmatter and never enrolled, silently zeroing the quote-tweet → newsletter funnel.
• Skill npm bundle synced to 0.16.3. The npm-bundled skill copy lagged at 0.16.0 even though 0.27.0 documented 0.16.3.

Changed

• Author's Voice plugin is now a pure proxy. Removed the engine config key, AV_ENGINE env var, and per-request version injection; the Author's Voice API now owns the v1/v2 default (AV_DEFAULT_ENGINE).
