Intent
outcome
Let reviewers group related Specs without introducing a second truth-bearing artifact.
Model
Pack line 18 · specs/model/pack-aggregate.sdp.md:18
An authored aggregate that groups related Specs for ideation and review while stating no system truth of its own.
framing line 19 · specs/model/pack-aggregate.sdp.md:19
A plain descriptive note explaining why a Pack exists; it is not Spec intent.
membership line 20 · specs/model/pack-aggregate.sdp.md:20
A declared manifest reference that derives a belongsTo edge; a Spec may belong to many Packs.
modelRefs line 21 · specs/model/pack-aggregate.sdp.md:21
References from a Pack to standalone model Specs that carry shared vocabulary.
priority order line 22 · specs/model/pack-aggregate.sdp.md:22
The authored member order of a Pack whose manifest states order: priority, read as its owner's advisory preference among its members; it confers nothing and sequences nothing.
refinement line 23 · specs/model/pack-aggregate.sdp.md:23
A truth-bearing parent-child relation, distinct from the cross-cutting Pack aggregate.

Decisions

  • Packs group review context without becoming truth

    A Pack declares membership and framing while stating no system truth; Specs may belong to many Packs.

  • A roadmap states advisory priority in the graph

    A roadmap is a Pack whose manifest states order: priority; its members' authored order is the corpus's advisory priority, first entry first. order is an optional manifest field whose one lawful value is priority, and a Pack without it keeps the reading order every Pack has. Priority is preference among bodies of work and nothing more: it carries no date, no dependency, no status and no gate, and no check, recipe or page treats a place on a roadmap as permission, obligation or sequence. Everything a roadmap shows about an entry, what it still needs and what holds it, is read from the graph each time. A corpus may keep several roadmaps, and a Spec may be listed on any number of them.
