Matrix Workflow
An evidence-driven development workflow with Prim and Arch orchestration, inspired by [Comet](https://github.com/rpamis/comet). Matrix can work with its own capabilities or conditionally invoke a verified cohort of [Matt Pocock's agent skills](https://github.com/mattpocock/skills) without giving up lifecycle ownership.

Why Matrix
[Matt Pocock's skills](https://github.com/mattpocock/skills) provide focused capabilities such as `/grilling`, `/tdd`, and `/code-review`. Using independent tools without a lifecycle owner leads to common problems:
- No process memory: You grill, then implement, but there's no record of what was decided
- Phase confusion: Did we finish design? Are we in build? Hard to tell after context loss
- Silent scope creep: Requirements change mid-build without returning to design
- Missing evidence: "Looks done" without verification proof
Matrix solves this with one deterministic state machine, explicit phases, guard conditions, and artifact tracking — inspired by [Comet](https://github.com/rpamis/comet)'s phase-based approach. Skills can assist a phase, but Matrix always owns the lifecycle.
What It Does
Matrix provides two capability-orchestration modes over two centrally defined workflow profiles:
full: open → design → build → verify → archive
hotfix/tweak lightweight: open ─────────→ build → verify → archive
Prim: Matrix performs p
