Phase 4 — Maturity (Status)

Unit type: Phase Unit ID: phase-4 Status: ⏳ Placeholder — sub-programmes sized after Phase 3 measurement Last updated: 2026-09-22 Plan: phase-4-plan.md Sketch: phase-4-sketch.md

Current state

Decomposed from the epic on 2026-09-22. This phase is not sized and cannot be until Phase 3’s P3.6.1–P3.6.3 benchmark, load-test, and cost-model outputs exist.

Blockers

Blocker Detail
Phase 3 exit gate Hard dependency
Sub-programme sizing Depends on Phase 3 measurement data that does not exist yet

Non-goal (not a blocker — a standing decision)

P4.7 (multi-region) is explicitly not built, reviewed annually. Recorded here so it is never mistaken for “not started yet.”

Next steps

  1. Wait for Phase 3 exit gate and its measurement outputs.
  2. At P3.6.4, size and expand this phase’s sub-programmes.
