jschoubben 902739acb6 Research 011 — the module graph
The proposal to split modules into provisioning services and applications was
worked through and abandoned, for a reason worth keeping: it cannot be filed
consistently. A git forge is consumed as a service and operated through a web
interface; an analytics service grants tracking identity and is a dashboard.

The operator's correction is the sharper form — what runs on the machine is a
supervised container, not something a user started. That is a fact about HOW a
thing runs, not about what kind of thing it is. So it is a facet, and 0002
survives: everything is a module.

What the catalogue is missing is not a taxonomy but a graph. Grouping asserts
relationships; a graph records them. Five declarations, of which two exist:
requires/provides a resource (yes), requires/excludes another module (no),
requires a node capability (no). Plus interface modules that carry no
implementation, with adapters providing them.

Recorded because it matters: this is a package manager's model, and pacman
already has all of it — depends, conflicts, and provides as virtual packages,
which is exactly the interface/adapter idea. Arriving there independently is
evidence for the shape. It is also a warning about what not to reimplement.

Working position on capabilities, to be tested: intrinsic ones (hardware,
architecture, network position) are detected and never installed, and a module
requiring one it lacks is impossible rather than unresolved. Provided ones (a
display server, a container runtime) are not a separate kind of thing — they are
modules that provide a capability, so "may the mesh install a capability" is not
policy, it is dependency resolution. Issue 007 then bears directly: an installed
package is not a capability.

Also captured: the operator's assessment that the machinery around a module —
scheduled tasks, hooks, migrations, config and env — is worth keeping, seeds are
not, and the integration is wrong enough to need a major refactor. Research 005
found supporting evidence from another direction, that the densest apparent
coupling in the catalogue is manifest boilerplate churn.

The first open question is the one that decides whether this is progress: what
does the graph DELETE? If modules gain declarations and lose nothing, it is
motion.

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.
