Deploying checked three things — the name is free, the server row exists, the directory isn't taken. Nothing asked whether the box could carry the thing, so a 2 GB app landed on a 1 GB VPS at full speed and the first sign of trouble was the OOM killer. Every piece was already here and unconnected: templates describe what they cost (`requirements: memory / storage`), servers report what they have (Server.total_memory / total_disk) and what they are using (the newest ServerMetrics sample). This is the join, answering in the shape a person asks it — does it fit, will it be tight, or can't we tell? Advisory on purpose. It reports; it never refuses. An estimate is an estimate, real usage depends on configuration and traffic, so the operator keeps the final say and "tight" is a sentence to read rather than a wall to argue with. A full server still returns valid:true, and a test asserts that so this cannot quietly become a gate. Three judgements worth stating: - The reserve is a floor-and-fraction pair (10% of the box, at least 256 MB RAM / 2 GB disk). A bare percentage is wrong at both ends: 10% of 1 GB is nothing, 10% of 64 GB is more than most apps need. - `unknown` outranks `ok`. No recent sample, or a template that declares nothing, says so — a confident wrong answer is worse than no answer. - Free memory comes from psutil's `available`, not `free`: cache and buffers are reclaimable, and counting them as used calls every healthy Linux box full. Catalog coverage goes from 52/106 to 106/106. The 54 estimates are each app's typical idle-to-light-use footprint, taken from the project's own documented minimum where it publishes one and rounded to the values the existing 52 already use — sonarqube 4 GB because that is its documented heap floor, immich 4 GB for the ML models, prometheus 20 GB because retention dominates, traefik 256 MB. Surfaced two ways: a capacity block alongside (never inside) `errors` on validate-install, and a read-only GET the deploy drawer can poll while the operator is still choosing a target, so the answer updates as they switch servers instead of waiting for a submit.
