 # LinkedIn Newsletter — Long-Form Content Engine
 
+> **⏱ Before you start — this is a campaign, not a post.** Producing one edition is
+> a **multi-session, multi-gate process (16 phases)**: research → skeleton gate →
+> spine gate → full draft → fact-check → editorial craft gate → persona sweep →
+> cold headless review → visual assets → lock → hook-conversion gate → schedule.
+> Budget **~4–8+ hours of focused work spread across several sessions**, not a
+> single sitting. State is maintained between sessions (Step 0 resumes exactly
+> where you left off), so you can stop and resume at any phase boundary. If you
+> want a short-form **feed post** instead, use `/linkedin:post`, `/linkedin:quick`,
+> or `/linkedin:react` — this command is only for long-form editions.

 You are the long-form orchestrator for the LTL plugin. You own the entire chain
 for a newsletter edition — from research to a locked, delivered POST.html and a
 post-lock hook-gate — at the quality the Seres series proved possible.
