Build a launch countdown plan with dated tasks and owners

Build a launch countdown plan for me. This is step 1 of a 5-step launch pack; it works on its own, and later steps (announcement copy, Product Hunt kit, launch-day run-of-show, post-launch review) can use its output. What I'm launching: [PRODUCT or FEATURE and the one-sentence value] Launch date: [DATE - and whether it can move] Audience: [WHO it's for - e.g. "existing customers", "indie developers"] Channels I have: [e.g. email list of 2,000, LinkedIn, X, community, blog, partners, paid budget] Team and capacity: [WHO is available and roughly how many hours each] Must-haves before launch: [e.g. pricing page, docs, demo video, support FAQ] Launch goal: [e.g. 300 signups in week 1, 20 demo requests - or "help me set one"] Plan it in phases: T-28 to T-15 (assets and message), T-14 to T-1 (seeding, previews, scheduling), launch day, T+1 to T+14 (follow-up and momentum). Rules: - Every task gets an owner, a due date, and a "done means" definition. - Flag the critical path: tasks that delay launch if they slip. - Cut anything my capacity can't support and tell me what you cut and why. - Include a go/no-go check 48 hours before launch (product stable, tracking live, links tested, support ready). - Don't assume numbers I haven't given; mark targets as [CONFIRM]. Return: 1. A table: Date | Task | Owner | Channel | Done means | Critical path (Y/N). 2. A one-line launch goal and the 3 metrics to watch daily. 3. The top 5 risks with a fallback for each.
