jschoubben dea46c3c6c Correct what the coverage document said about actions
I wrote that a module cannot declare an action. It could — the parser
accepted one, and the refusal only came on the machine. The claim was
wrong in the direction that matters: it read as "the design prevents
this", when what prevented it was a check at the far end that nobody
would connect back to the manifest.

Health checks are still the gap most worth closing, but the shape of the
answer is different from what I wrote. An action is not available to a
module at all, so a health check needs a way to say ask this and expect
that without saying run this — closer to a listens entry than to an
action.

Also records the finding itself, because it is a recurring shape here
and not a one-off: a rule enforced only at the far end is enforced and
unusable.

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 ADR 0009 is superseded by ADR 0009: there is no domain module to group into, so there is no domain list to settle.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.
