jschoubben de7358a2c5 Design 47 takes in round 1 of the review by architectural domain
The reviewers found the amendment left the stores to grow without a bound,
the waits without an owner's tools or events, a rollback that would send nodes
back to old builds, a newer indexer that could never be wanted, events any
account could forge, and the node-engine reading every node's placements. The
design now chooses, each with its reason: a default record retention and caps
with fill conditions, a revision removed when no record pins it and it is not
current, waits held and released by each step's own part with their events,
the build module's wait ending on the agreed toolchain, the old keys kept
written until a named milestone H for a rollback, the running indexer making
the newer indexer's entry, rule changes named by the running checker from
outside the sandbox, and subjects and grants that let each part say only its
own. The review verb leaves milestone G for issue 1782, and the watcher's
definition goes back to main, since it contradicted an approved instruction.

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.
