The consolidation left a sparse sequence -- 1, 4, 6, 7, 9, 10, 12, 15, 16, 18, 19, 25, 34, 35, 36, 37, 40, 42, 44, 45, 48, 49, 58 -- where the gaps were only the archaeology of what used to be there. Renumbered contiguously. Renames run in ascending order, so every target number is already free and no two files ever collide. The reference rewrite is one simultaneous pass rather than a sequence of replacements. Numbers moved into slots other numbers were vacating -- the node host went 37 to 16 while the lab went 16 to 9 -- so replacing one at a time would have cascaded and silently pointed things at the wrong record. Seven plain-text references survived the merges as prose rather than links, naming records that no longer existed: the enrolment token, the link boundary, what a declaration is, reachability, the repository structure. Each mapped to the consolidated record that now holds it. Verified rather than assumed: every [ADR NNNN](path) link now has matching text and target, checked across the whole repository, and the checker passes. Frontmatter `consolidates:` lists dropped -- they named records that are gone, and each consolidated record already says in prose what it absorbed.

# 002 — A mesh that runs locally
|
|
|
|
- **Initiated by:** jochen, 2026-08-22
|
|
- **Areas touched:** `install.d/`, `hal/meshware`, `hal/coordinator`, `hal/brain`,
|
|
`hal/developer` (`dev_up`), `hal/sdk` (env generation, feature handlers, artifact
|
|
manager), `test/pipeline/`, `test/dev-mesh/`, the provisioning path in
|
|
`modules/postgres/`.
|
|
|
|
## Summary
|
|
|
|
Phase 0 of [`03-DESIGN/00-work-breakdown.md`](../../03-DESIGN/01-to-be/00-work-breakdown.md) requires
|
|
a mesh that comes up in containers, runs its own pipeline, and reproduces known faults on
|
|
demand. Nothing else in the decomposition starts until it exists, because every fault the
|
|
decomposition addresses was found in production — there was nowhere else to find it.
|
|
|
|
This effort establishes what already runs in a container, what is welded to the host, and
|
|
what it would take to close the gap. It does **not** choose an approach: the central
|
|
question — how a containerised node executes a module service, when a module service is
|
|
defined today as a systemd unit shelling to `docker compose` in `/services/` — is not
|
|
answered by ADR 0008 and is recorded below rather than decided.
|
|
|
|
## What was established
|
|
|
|
- The two existing container harnesses are **neither of them a mesh**, and one of them has
|
|
not been able to build since 2026-06-04.
|
|
- Node identity is already portable — a single environment variable, no host handshake.
|
|
- Four concrete host couplings block a containerised node, all with known locations.
|
|
- All three Phase 0 fixtures are reproducible; one of them is documented in the knowledge
|
|
base with an open root cause and is the cheapest place to start.
|
|

Detail and evidence in [`analysis.md`](analysis.md).

|
## Questions — all settled 2026-08-22
|
|
|
|
**Phase 0 is a development environment**, not a fixture rig — it is what the host-borrowing
|
|
dev tooling becomes.
|
|
|
|
**The trigger is a real source-forge container**, because the webhook relay is part of what
|
|
is under test.
|
|
|
|
**A node is a system container**, promotable to a virtual machine per node. This answered
|
|
the question the effort was stuck on, and dissolved it rather than solving it: against a
|
|
real node with a real init, the four host couplings catalogued in `analysis.md` §3 are not
|
|
couplings — they are how a node works. They were obstacles only to a node modelled as an
|
|
application container.
|
|
|
|
Consequently [`003-service-supervision`](../003-service-supervision/) **no longer blocks
|
|
Phase 0**. It remains a live architecture question, on its own timeline.
|
|
|
|
The remaining questions in `analysis.md` — what replaces host paths in a container, and how
|
|
faithful the lab must be — are answered in the design: nothing replaces them, because the
|
|
paths are real; and the divergences are enumerated rather than discovered.
