jschoubben 8f75606167 Designs 25, 51: follow review round 1 of the registry milestone
Design 25 counts seven first-view tools, the indexer's graph granted to the
assigner alone (ADR 0631); the bus module's process wakes on its own decided
and acts on a warrant once (ADR 0259 §6, ADR 0620 §2) instead of a timer, and
the tools watch their request key; §12.7 carries the rows, and its first-view
row, split by an earlier edit, is one row again. Design 51's incoming store
asks the objects template's most, 8 GiB, with no lifetime; the holder drops an
idle transfer itself (ADR 0611 §3).

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.
