Stacks

35 stacks.
Each one tells you what to skip.

Every stack leads with the situation it solves, lists what was considered and explicitly rejected, sets the kill condition that signals it's time to move on, and points to the next stack you graduate to. Opinions baked in — no generic catalogues.
