jschoubben c098518cc8 Design 25: the grants part asks the bus module for every binding at its start
A binding was written only on the bus module's live created event, so one
event the grants part never heard lost the binding for good (issue 1966):
a registry holder lacked three entries the bus held, and its publishes
were never said published. The operator chose to ask the bus module: at
every start and on a re-ask the grants part takes a first view from the
seat mesh-broker's list, whose entries now carry their binding, and
composes the bindings from it; a binding the bus no longer lists is kept
and said, never removed by a first view.

The same change puts design 25 in playbook 02's shape: section 12.2 to
12.6 move, unchanged and numbered, into the part of milestone bus-state,
so the main file falls from 104 KB to about 71 KB.

03-DESIGN

The authoritative specification. Implementation is built against what is written here.

Two layers

Folder What it is
00-as-is/ The mesh that exists today. Shipped behaviour, described as it is — including behaviour nobody would choose again.
01-to-be/ The mesh being built toward. Every statement traceable to a decision record in the knowledge base (ADR 0290).

They are never mixed. A statement about the future does not belong in an as-is document, and an as-is document is never edited to describe an intention.

When a to-be design ships, it does not move. Its as-is counterpart is written or updated, the to-be document's status becomes implemented, and both stand — one describing what runs, the other recording what was intended. Deleting the intention loses the reasoning, which is the expensive half.

Frontmatter

Every design document (not the READMEs) carries:

---
layer: as-is | to-be
status: designed | in-progress | implemented | abandoned
code: []                 # owning code repo(s), from 00-META/repos.md
updated: YYYY-MM-DD      # date of the last status change, not of text edits
decisions: []            # the decision records this document rests on, each "ADR NNNN"
---

For an as-is document, status: implemented is the normal state — it describes something that runs — and code: names where that implementation lives.

Status changes when implementation state changes, never because design text was edited. An implemented claim must be defensible from the owning repository's main branch, not from intent. If it cannot be checked, it is in-progress.

Cross-cutting views are generated from this frontmatter by the hq-status skill and never written to disk.

What belongs here

Functional analysis, architectural description, and specification — prose and diagrams only, no code. A manifest field may be named; a manifest may not be pasted. A document enters the to-be layer only after the decision behind it is recorded in the knowledge base and the research that produced it is closed.

Subfolders are encouraged where a layer grows enough to need them.
