What this is A companion to the full technical map: every one of the 365 categories tagged Small, Medium, or Large by typical engineering effort to deliver a usable first version — from a few days (Small) through a few weeks (Medium) to several months (Large). Use it to spot quick wins, triage a backlog, or sanity-check a roadmap before committing.
What it is not A precise estimate. Costs shift with your stack, team, and existing foundation. A category tagged Large may be small for you if you already have the primitives; a Small may be large if it conflicts with your architecture. Treat the badges as relative weights, not promises.
How to read it Grouped by 10 rings — concentric layers from Ring 0 (special needs, applies to everything) through Ring 8 (frontier tech, watch but do not build yet). Within each ring, every category carries its cost badge. Filter by cost level, search by name or number, and use the theme toggle for light or dark reading.
How to use it In a planning session, filter to Small only to find the quick wins; filter to Large only to see what needs a dedicated team or a phased approach. Combine with the main map: pick the categories that matter, then use the cost badges here to sequence them.
