0036 (accepted): a node is a managed machine, and disconnection is a situation. The open question posed a class distinction — full nodes and lesser presences. There is none. Reachability is state, not kind, which promotes the host's local store from a component to a requirement: it is what makes disconnection ordinary rather than exceptional. The reduced contract the question reached for is real but it is capability, and that belongs in the profile. 0037 (accepted): the host applies, it does not decide. Measured rather than argued — the absorption is smaller than the machinery that already applies state, and eight of ten adapters carry no dependency to move. The two that do open a Postgres connection to the control plane, which inside tier 0 is the one thing the tier rule exists to forbid. So each concern splits: deciding needs every other node and stays in tier 2; applying needs root and locality and goes to tier 0. The host carries ONE concern, of which the six are instances. 0038 (proposed): a node joins by linking first. The operator's two-modes proposal, adopted as intent and corrected as structure. Two modes is two code paths where the first runs once per mesh and rots — and the mesh already has that fault in its worst form, as three hand-run shell scripts. Instead: one behaviour, two sources of declaration. The first node is not a different kind of node, it is a node whose mesh is not up yet, and its specialness is temporary and self-erasing. 0038 also shrinks the migration 0037 called expensive: a joining node never needs mesh-wide state, because the hard part of the overlay is only needed to compute the WHOLE mesh. It needs one peer. The rest arrives. Left open and said so: what may be pushed over the link and how a joining node proves it is entitled to join, and whether one host can raise the substrate alone.
01-RESEARCH
Investigations that have not yet hardened into design.
Structure
Each effort lives in NNN-descriptive-name/ and must contain 00-overview.md, carrying its
state in YAML frontmatter and a prose summary below it:
---
status: active | graduated | abandoned
initiated: YYYY-MM-DD
touches: [] # design docs, subsystems or areas the effort bears on
became: [] # required when status is terminal — what it turned into
---
The prose says what is being investigated, why, and what it touches. It does not restate the status — status lives in one place, and two places is one too many.
Further documents in the same folder hold the work itself: notes, evidence, option analyses, draft designs.
Lifecycle
| status | Meaning |
|---|---|
active |
Investigation in progress. |
graduated |
Checked against 00-META, decided in 02-DECISIONS/, and specified in 03-DESIGN — see became:. |
abandoned |
Stopped or superseded. Nothing is deleted. |
An effort graduates by producing a decision record and a 03-DESIGN entry. It is abandoned
in place — never deleted. What was rejected, and why, is the more expensive half to
rediscover.
Starting and closing efforts is playbook territory:
00-META/process/01-research.md and
02-graduation.md.
Rules
- Markdown only. Do not skip or reuse a sequence number.
- Evidence, not assertion. An effort that measured nothing has not finished.
- Research describes real observations but never identifies the mesh it observed. The shape of a finding survives anonymisation intact.
