Designs 51, 32: the windows wake on the node-engine seat's manifest-reads-changed (ADR 0618), and every build stays readable by every counted node-engine (ADR 0624) #513

ADR 0618 and ADR 0624 are accepted (ADR 0624 supersedes ADR 0623); designs 51 and 32 cited 0618 as "to be decided".

Design 51: the old seat name's window and the old-form window wake on mesh.seat.node-engine.event.manifest-reads-changed and read each node's stated capabilities with the node-engine seat's manifest-reads (ADR 0618 §3-§4), never a watch of the node-engine's have state; distribution and the builder declare the verb in invokes and are granted the event. Every build keeps each reference form a counted node-engine states, away nodes included until retired, a node that states nothing counting as the baseline; the oldest kept form is the build key's single reference; a node is held from a build only when it reads none of its forms (ADR 0624 §1-§3), never by a module's name (ADR 0601 §4), so an away node with an old node-engine still gets every build, the node-engine's own included.
Design 32: the rename window wakes on the same event; the next delivered stays only for a build applied after a node's return, which ADR 0618 does not cover; mesh-config's grant named.
Tests: a grants-part row (only the three modules subscribe to the event), builder cases for present and away nodes, holder and rename cases with no delivered and no timer.

Review record: review by architectural domain (playbook 01), security and upgrade, round 1 at f47744a (two musts, two notes), answered at 48fa0a5 and checked by the lead; the ADR 0624 commit (cac55dc) read by the lead against the accepted record. go test ./... passes.

Designs 51, 32: cite ADR 0618 for the windows' wake and the reference form f47744a8b6

ADR 0618 is accepted: the node-engine seat's manifest-reads verb and its
manifest-reads-changed event wake the old seat name's, the old-form and
the rename windows, and the builder writes a new form only once every
present node-engine states it. The next delivered stays only for the
rename window's case the record does not cover.

Designs 51, 32: name the manifest-reads grant and who holds the old-form window 48fa0a5a48

The upgrade and security review asked that each window's caller be
granted the event through its invokes, that an away node be held by the
assigner rather than the old-form window, and that a node-engine not yet
serving manifest-reads keep a window open by name.

Design 51: keep the node-engine's own build readable by away nodes (ADR 0623)

Under ADR 0618 alone a node away with an old node-engine would be held
from the node-engine's own build in the new form and could never update
itself. ADR 0623 keeps every counted node-engine's form in those builds
and moves them to a node that reads any one of them.

Design 51: follow ADR 0624, every build keeps each counted node-engine's form

mesh/delivery merged: source.main moved to novox/hq@273d608d9faa

Details

mesh/check being carried to cac55dc2543a on 273d608d9faa | from 6cd965b3cdf6

ADR 0624 supersedes ADR 0623, which could find the node-engine's own
builds only by the module's name. Every build now keeps each form a
counted node-engine states, the oldest in the single reference, and a
node is held only when it reads none of them.
