mesh/merge-gate head 79a3396340a7 merged into trunk 454a3db69a1e — pass: builds build-agent, mesh-controller → ace, g14, novox, shanks; no bus step; every …
A controller older than optional requirements reads `requires` as names, and Inventory.Catalogue
stops at the first manifest it cannot read: the long form stored inside `requires` would have left
a rollback below this controller composing no machine. Stored, `requires` stays plain and the
optional names sit in `optional-requires`, a key an older controller sets aside, leaving out only
the module carrying it. A refusal of a hard requirement now names a module that wants it hard.
Making every soft dependency a provision made it hard: a mesh without influxdb could not assign
grafana, and one with influxdb in its catalogue would install it for grafana. A requirement may now
be written {"name": ..., "optional": true}. It resolves as a hard one when a provider is assigned or
reachable, and is otherwise absent: never refused, nothing installed for it. Its binding, credential
and only-when-bound files are left out, its ${bound:...|default:...} placeholders take their
defaults, the module check refuses one that could render empty, and plan and node list it unbound.
