Two layers. The **node** table maps each knowledge-system attribute to the methods that produce it, split by track; the **edge** table below maps each cross-domain relationship to the [[Context Mapping]] pattern that resolves it. Methods listed here already have notes in the vault; the upward `[[Attribute]]` links on each method note are not yet wired — that work is deferred. "—" marks a track where no method-layer answer applies (typically a tool-layer concern).
| Attribute | Personal methods | Collective methods |
|---|---|---|
| [[Discoverability]] | [[Zettelkästen]], [[PARA method]], [[Build a Second Brain]], [[Single source of truth]] | [[Experts Hub]], [[Expertise Radar]], [[Single source of truth]] |
| [[Maintainability]] | [[CODE method]] (Distill step) | [[Single source of truth]], [[Decision log]] |
| [[Connectivity]] (intra-domain) | [[Zettelkästen]], [[Build a Second Brain]] | [[Expertise Radar]] |
| [[Interoperability]] (inter-domain) | — | [[Context Mapping]] - [[Published Language]], [[Open Host Service]], [[Shared Kernel]], [[Anti-corruption Layer]] |
| [[Survivability]] | [[File over app]], [[Local-first]] | [[File over app]], [[Local-first]] |
| [[Securability]] | — | mostly tool-layer |
| [[Ownership clarity]] | — | [[RACI]] |
| [[Agent-readiness]] | [[Schema-on-read]] | [[Schema-on-read]], [[Decision record]], [[FAIR principles]] |
| [[Captureability]] | [[CODE method]] (Capture step), [[Zettelkästen]] (fleeting notes) | [[Decision record]], [[Post-mortem]] |
| [[Tacit-externalisability]] | weak — [[Lesson interview]] | [[Decision record]], [[Decision log]], [[Post-mortem]], [[Mentorship]], [[Experts Hub]], [[Lesson interview]] |
^table
## Between domains — relationship → pattern
The inter-domain edges that the [[Interoperability]] row stands for: given a cross-domain relationship, which [[Context Mapping]] pattern resolves it - gated by the owning domain's Core / Supporting / Generic class.
| Edge-property | Pattern |
|---|---|
| [[Common demand]] | [[Shared Kernel]] - centralise into a common domain, co-owned |
| [[Broadcast supply]] | [[Open Host Service]] + [[Published Language]] - publish one standard interface |
| [[Directed dependency]] | [[Customer-Supplier]] - a committed supply agreement (or [[Conformist]] with no leverage) |
| [[Model mismatch]] | [[Anti-corruption Layer]] - a translation buffer (watch the duplication cost) |
| [[No real coupling]] | [[Separate Ways]] - a deliberate non-integration |
| [[Unbounded tangle]] | [[Big Ball of Mud]] - wall it off, don't extend |
