jschoubben 3a9b47918d ADR 0050 (proposed) — model access is vendor-agnostic; amend 14-model-access
Turn the completed vendor-agnostic analysis into HQ design. The model-access
provision stays one vendor-blind interface (extends 0024/0027); the
vendor-specific lifecycle moves into a per-vendor adapter keyed by the licence's
`vendor` field, mirroring registrar-scoped public-dns providers (0044), named at
the consumer's real coupling per 0040.

The crux is the sealing-vs-central-rotation carve-out: for refreshable-grant
vendors only, the manager node holds the refresh token encrypted at rest (a
bounded, declared exception), access tokens sealed per holder, refresh stripped
on delivery. Static-key vendors keep full sealing.

Amend 03-DESIGN/01-to-be/14-model-access.md with the adapter generalisation as a
proposed section (prose + diagram, no code); regenerate the decision index.

03-DESIGN / 01-to-be

The mesh being built toward. Every statement here traces to a record in 02-DECISIONS/; nothing arrives by drafting.

A document here describes an intention. What currently runs is in 00-as-is/, and the two are never merged — when something ships, the as-is document is written and this one's status becomes implemented.

Not yet written

  • The remaining six contexts. ADR 0006 settles the list at seven; connectivity is the first written in full (08) and the other six do not exist yet. The work breakdown says in what order they are needed.
  • Domain grouping outside the core. Not needed. ADR 0009 is superseded by ADR 0009: there is no domain module to group into, so there is no domain list to settle. Relationships are edges, and grouping is a tag and a query.
