jschoubben 36d342f176 What a module must be able to say, measured against 127 that exist
Every manifest in the system being replaced was read and every key
counted, then set against what the new one can express. Three findings
worth more than the table.

**The most-used key was already covered and I expected a gap.**
Depending on another module — 65 manifests, the commonest thing any of
them says — is a requirement naming a module, which already means that
module rather than anything providing the name.

**The largest real gap is tool servers: 56 modules, over half.** A
module can already run one; what is missing is anything saying it offers
tools. That is plausibly a provision rather than new vocabulary, which
would need nothing added — not yet decided, and recorded as undecided.

**The gap most worth closing is health, at seven modules.** The mesh
knows a container is running, which is not whether it answers, and this
project has paid for that distinction twice. An action with a verify is
exactly the right shape and may not arrive over the link, so a module
cannot declare one.

Two things are missing deliberately and say so: stage hooks, because the
link may not carry an action and a module needing setup ships a program;
and flavours, retired in favour of claims.

Config merging is missing and should stay missing. A mechanism that
understands TOML gets asked for YAML, then INI, which is how the thing
being replaced became unholdable.

Also records what the survey found that is not about coverage: manifests
that had stopped matching what was actually brokered, one fact derived
in two places giving two answers, and a live listing returning
credentials in plaintext.

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 record in 02-DECISIONS/.

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: []            # 02-DECISIONS/ records this document rests on
---

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 02-DECISIONS/ and the research that produced it is closed.

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