0049: a public name is provisioned like any capability — a module requires public-dns and contributes its host; a neutral interface answered by registrar-scoped providers (cloudflare-dns, route53-dns) that create/remove the record pointing the name at the mesh's public ingress. Pairs with route (the proxy) and a public cert (the proxy's ACME). 0050: answers the firewall question. The firewall is NOT a provider like the proxy — it is a machine's own filter, derived by the host as the sum of what its modules declare they listen on, with 'from' the whole of public-vs-internal. Enforced both ways, unknown keys refused — closing 04-ISSUES/003. A public service is exposed through the proxy (listens from:mesh + requires route), not by opening its own port.

02-DECISIONS
Architecture decision records — the "why" trail behind the rules in
00-META and the specifications in 03-DESIGN.
Numbered 02 because a decision precedes the design it authorises. Research concludes,
the decision is recorded here, and only then is the design written. Following the folder
numbers walks the process in the order it happens.
One file per decision, numbered, never deleted. A superseded record has its status: changed
and gains a pointer to what replaced it — its text is never edited. The reasoning that was
rejected is the expensive half to rediscover.
The records run in the order the decisions were taken, oldest first.
Every decision is a record. There is no ledger and no index file — if a decision is worth
recording it is worth a record, and if it is not worth a record it is not recorded
(ADR 0026). A "decision" small enough to be one line is
almost always a rule, and a rule belongs in
00-META/how-we-build.md, where it is enforced and keeps the
incident that earned it.

Body
# N. Title in plain language
## Context what was true, with evidence
## Considered Options numbered, each with why it was rejected
## Decision what was decided
## Consequences what follows, including what got harder
## References commits, pull requests, knowledge-base entries, prior art
State evidence, not assertion. "Zero of 124 modules declare brain as a dependency"
outranks "the dependency rule is not followed".
Reconstructed records
Records 0001–0014 were written on 2026-08-23, after the decisions they describe. Records 0015 onward were taken as records. Those
decisions were taken in implementation rather than in a document; the records state what was
decided and the evidence it was decided from, and each carries reconstructed: true and says
so in its first lines.
A reconstructed record is not a transcript. Where the deliberation is not recoverable, the options section states what the alternatives were and why the chosen one won on the evidence available — not a discussion that did not happen. Where a date is not establishable it says so rather than guessing.
Index
The index is generated, not maintained — run the hq-status skill, which reads the
frontmatter of every record. A hand-written index drifts from the folder it describes, and
this one had already done so after a single addition.
