jschoubben 84bb85d037 Design 39 bus-and-switch: the licence manager keeps its data on the bus and switches on its own usage
The operator, 2026-11-11: the licence manager itself moves every consumer off a
licence at 99 % of its session or weekly window to the licence with the most
room, configurable, with its Postgres database replaced by bus state and tools
for all it keeps and does. That night a session meant to switch missed the
readings, so no session does it any more. The new milestone part writes every
line it builds (kept data, the one carry-over of today's rows, the vault move
of ADR 0550 §3, bindings and holdings as events, the switch, its warning and
condition, the tools, adding a licence), and names the three questions no
record settles; the main file is put in the shape a builder reads whole.

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.
