jschoubben f05e4a0dce Follow papa-hq's research convention; the mesh links nothing
Research efforts move from status.md to 00-overview.md with active /
graduated / abandoned, matching papa-hq so the two repositories read the
same way. Playbooks, skills, README and the ledger follow.

Reverses yesterday's withdrawal of the symlink note in GENESIS. The note
was right and the withdrawal was wrong: the intent is that the mesh
creates no symlinks at all, so a founding document listing "symlinks, not
copies" as a design principle does point the opposite way from where this
is going, and that is a contradiction rather than a stale detail.

ADR 0018 records the position, proposed. ADR 0011 stays as it is — it is
the historical decision and the incident behind it is why anyone believes
either record — and is superseded in intent, not edited. Its one
editorial line, which called the wider reading false, is corrected to
state what is actually true: centralising who may link narrowed the
incident class without closing it, because a link the installer makes
resolves exactly like one made by hand.

The argument that kept linking was staleness. ADR 0004 removed it: every
managed file is already derived and reconciled, so a copy is the natural
form and a pointer into source is the shape the mesh's own model forbids
everywhere else. What is not settled, and is marked open, is how
staleness gets detected — which is the decision that makes or breaks it.

Raw Blame History

Decision ledger

Every decision, in the order it was taken. Append-only — a decision that stops being true is marked superseded and left in place, because the reasoning that was rejected is the expensive half to rediscover.

An entry here is a record, not the reasoning. Anything architecturally significant carries its full context, options and consequences in an ADR; anything still being worked out lives in 01-RESEARCH. This file is the index that makes both findable, and the place small decisions live that never warrant a document of their own.

Columns. Decided is who made the call. Where points at the reasoning. A decision with no pointer is one small enough that this line is the whole record.


2026-08-22 — decomposition

# Decision Decided Where
1 The mesh brokers capabilities; nodes host; agents think. Eight bounded contexts replace 33 platform modules. jochen ADR 0015
2 Nodes and agents decouple — a node holds no licence; an agent holds credentials and delivery follows its bindings and modality. jochen ADR 0015
3 noxflow dissolves; hal/work inherits tasks and workflows. jochen ADR 0015
4 Third-party modules leave this repository — they run on the mesh, not of it. jochen ADR 0015
5 Documentation lives inside the code repository under hq/. jochen Superseded by #27

2026-08-22 — the lab

# Decision Decided Where
6 Phase 0 is a development environment, not a fixture rig — it is what the host-borrowing dev tooling becomes. jochen 002
7 The delivery trigger is a real forge inside the lab, not a synthetic event — the webhook relay is part of what is under test. jochen 002
8 A lab node is a system container, promotable to a virtual machine. jochen Superseded by #10
9 Adoption is a legacy path and is out of scope. Bringing nodes into being is the lab runner's job instead. jochen design
10 A lab node is a virtual machine running the real install. Supersedes #8: the scale argument for system containers was invented rather than required, and a virtual machine dissolves the fidelity question instead of answering it. jochen ADR 0016
11 The environment is called the lab. jochen —
12 The lab is driven by incus — for virtual machines, snapshots and bridges through one interface, and because it also runs system containers if a scale run is ever needed. jochen ADR 0016
13 The simulated public segment uses TEST-NET-3 (203.0.113.0/24). Not cosmetic: an RFC1918 public segment makes the hub test as unreachable and the mesh silently never forms. — ADR 0016, 004
14 The lab issues its own certificates, keeping production's two-authority split rather than collapsing it. jochen ADR 0016

2026-08-22 — what the lab is for

# Decision Decided Where
15 The module is what is under test; the mesh is the harness. The loop is: change a module, run it end to end, get a verdict. jochen design
16 Nothing new drives delivery. A lab mesh has its own coordinator; the pipeline that runs is the real one. A second delivery path would be blind to exactly the faults worth catching. jochen design
17 A test runner is a legitimate component used by the coordinator — lab lifecycle and assertion execution. The line is the pipeline: a runner that decides what to build is a fork of the coordinator. jochen design
18 The runner has two callers — the coordinator, and a person developing the mesh — so it needs both a run-to-verdict verb and a leave-it-standing verb. jochen design
19 A module carries its own assertions, stated once, in the verification stage the coordinator already dispatches. Running them where failing is free is what makes writing them worth doing. jochen design
20 A test declares the mesh it needs; size ranges from one node upward, chosen by the question rather than by what the mesh happens to have. jochen design
21 The real topology is one test among many, not the baseline. Anything only testable there is a gap in the vocabulary. jochen design

2026-08-22 — working agreements

# Decision Decided Where
22 Never install packages by hand. A package is declared in the module manifest and arrives the way every other package does. jochen —
23 Never open a pull request unprompted. A permissions list saying it is allowed is not a request. jochen —
24 Every merge is a human checkpoint, without exception. jochen 02-DESIGN/01-to-be/00-work-breakdown.md
25 Work in an isolated worktree, never a shared checkout. jochen how-we-build §2
26 Decisions are recorded here, thoroughly, as they are taken. jochen this file
27 HQ is its own repository, hal-hq. Supersedes #5: the original objection was to a fourth knowledge system, which indexing answers rather than location. Cadence, reviewers, and a scope wider than one repository all argue for separation. jochen README
28 This repository is public. Written for a reader who is not its author and has no access to the mesh it describes. No routable addresses, real domains, hosting providers, node names, absolute paths, or operational detail useful only to an attacker. Supersedes the previous rule that research may name instances. jochen README

2026-08-23 — how this repository works

# Decision Decided Where
29 Design splits into two layers that are never mixed — 00-as-is describes the mesh that exists, 01-to-be the one being built toward. A design that ships does not move; its as-is counterpart is written and both stand. jochen 02-DESIGN/README
30 The as-is layer is written from the implementation and the operational record, not from intent, and records shipped behaviour nobody would choose again. An as-is layer that keeps only the good decisions is a brochure. jochen 02-DESIGN/00-as-is/README
31 HQ is the source of the mesh constitution. The governed page injected into design sessions is derived from how-we-build.md and never edited directly. Same one-source-many-surfaces argument as #27. jochen playbook 05
32 Every workflow is a playbook in 00-GENESIS/process/, wrapped by a thin skill that defers to it. Agents operate through the playbooks and not outside them. jochen process/00-overview
33 Issues get a front door, 04-ISSUES — design-level and governance faults only. Operational lessons stay in the knowledge base, which is indexed on symptoms. This repository is not a second copy of it. jochen 04-ISSUES/README
34 Decision records are a chronological ledger. Fourteen decisions already taken in implementation were back-filled as records 0001–0014, each marked reconstructed and carrying its evidence; the two existing records renumbered to 0015 and 0016. jochen adr/README
35 Status lives in frontmatter. No central status files; cross-cutting views are generated on demand. This file is a ledger of decisions as taken — an index, and the home of decisions too small to warrant a record — and explicitly not a status board. jochen process/00-overview
36 The ADR index is generated, not maintained. The hand-written one had already drifted after a single addition. jochen adr/README
37 Modules outside the platform core are grouped by domain, not by single function, extending #1. The principle is settled; the domain list deliberately is not. jochen ADR 0017
38 The mesh creates no symlinks at all — not by hand, and not by the installer. Centralising who may link narrowed the incident class without closing it, and a derived file is a copy by nature. The position is settled; the staleness mechanism is not. jochen ADR 0018
39 Research efforts follow the 00-overview.md convention, with active / graduated / abandoned in frontmatter — the same shape papa-hq uses, so the two repositories read alike. jochen 01-RESEARCH/README

Observations

Things established by measurement that no decision has yet answered now live in 04-ISSUES, one numbered folder each, so they can be diagnosed, owned and closed rather than accumulating in a table nobody can resolve.

Issue What it means
001 A failed package install does not fail the job. The first thing the lab was asked to install demonstrated the exact fault the lab exists to catch.
002 A declared package can fail purely because the node's index is old, and today that failure is silent.
003 A manifest can appear to restrict a port and restrict nothing.
004 Every certificate experiment on a real node consumes production issuance quota.
005 The repository's only end-to-end pipeline test has been silently dead since 2026-06-04.
006 This repository is not indexed into the knowledge base — the claim that holds up decision 27.

Deliberately not decided

Recorded so they are not mistaken for oversights.

Question Status
Which supervision model the mesh adopts — keep the host init system, drop the redundant per-module layer, containerise the daemons, or write a supervisor. Open. Options costed in 003. No longer gates the lab.
Whether the lab verdict is a workflow guard or an advisory check on the pull request. Open, and deliberately trivial — a policy detail, changeable in an afternoon, not an architectural choice.
hal/scheduler — infrastructure or part of hal/work. Open, from ADR 0015.
Which context owns the executor. Open, from ADR 0015.
Catalogue destination — one repository or many. Open, from ADR 0015. Phase 4.
What hal/sdk keeps after extraction. Open, from ADR 0015. Phase 3.
Where human agent modality is recorded — which user, on which node, a human agent acts as. Open, from ADR 0015. Required by the model; not yet stored.
