📖What it means

The one piece of code that knows how to talk to a particular vendor. Everything vendor-specific lives there and nowhere else, which is what makes a provider swappable instead of woven through the estate. Since 2026-09-27 (cost-center #172) every adapter keeps the one adapter contract -- work out the model, get a call-only sign-in from the sign-in door, make the call, name a refusal, prove itself, and renew only in the keeper -- and no adapter reads a sign-in or a key for itself. Image, voice and video are reached through adapters too.

📖Easily confused with

[{"term": "Model", "distinction": "The adapter is the plumbing; the model is what answers through it."}, {"term": "Shim", "distinction": "An adapter faces OUTWARD to a vendor; a shim faces inward between our own parts."}]

📖Also called
