[EPIC C5] Reusable and operated product platform #8
Description
Outcome
Proven reusable components or dependable operated services with versioned composition contracts.
Placement and activation
Master roadmap: #2. C5 activates by a second actual consumer or a specific hosted/service need. Select the library path, service path or both; each has its own dependencies.
Canonical numbering is C0–C6. Local source/review evidence is a prerequisite only for the selected path; whole optional epics are not universal release gates.
Child work
- #40 — Reusable engine extraction when two consumers prove it
- #41 — Consumer-tested APIs, SDKs and adapters
- #42 — Hosted persistence/governance only if state must persist
- #43 — Identity/admin only for actual governed accounts/instances
- #44 — Service infrastructure only when a service exists
- #45 — Reliability appropriate to the deployed service/installation
- #46 — Shared tooling, contracts, compatible versions and developer docs
Paths
A local reusable library can complete #40, #41 and #46 without accounts, a database or hosted SRE. A service can be deployed without first extracting the engine. Add #42 / #43 only if that service uses persistent data or identities. An installation's health/recovery can use its own runbook instead of a cloud stack.
Completion evidence
Record deliverable, source/score/software versions, exact-head checks, deployment identity where relevant, limits and artist decisions. Planning completion never establishes runtime or artistic acceptance.
