Map Content Lifecycle
Downloaded, verified, staged and active remain separate population truths.
Trace immutable source/build/quality evidence through entitlement, signed manifests, resumable delivery, atomic activation and last-known-good rollback.
Authority by layer
Know which component owns the state—and what it must never infer.
Every layer exposes an authoritative responsibility and an explicit non-authority boundary.
SAAS-04
Release control
OwnsQuality, compatibility, entitlement, manifest and rollout decision
Must not inferPublished is not downloaded or active
CDN/object path
Delivery
OwnsChunk integrity and durable package transfer
Must not inferComplete download is not verified compatibility
FW-05
Vehicle activation
OwnsVerified staging, atomic active pointer and last known good
Must not inferCloud cannot claim activation without device evidence
End-to-end operating flow
State advances through evidence—not optimistic UI.
Each transition names both the action and the identity or version evidence that makes it reproducible.
- 01
Build
Create immutable territory/layer package with full source lineage.
source/build/package IDs · reproducibility - 02
Qualify
Pass mandatory quality, compatibility, security and program approval gates.
check evidence · approver · release fingerprint - 03
Resolve manifest
Match vehicle, runtime, territory, entitlement and cohort revisions.
signed manifest · policy · dependencies - 04
Stage and activate
Download resumably, verify, stage and swap atomically.

Converge or roll back
Measure declared population states and restore last known good on failed health.

Contract families
Interfaces that a production program must own.
Release
Immutable package, lineage, quality and compatibility evidence.
Manifest
Vehicle/program/territory entitlement, dependencies and signature.
Device lifecycle
Downloaded, verified, staged, active, health and rollback states.
Population
Explicit denominators, cohorts, convergence and rollout decision.
Designed degradation
Failure states stay truthful and useful.
Invalid signature/integrity
Quarantine package and preserve the current active set.
Incompatible runtime/storage
Do not stage or activate; report exact preflight reason.
Power/network interruption
Resume download or boot the previous active set without partial activation.
Post-activation health fails
Move to rollback-pending and restore verified last known good.
Security & privacy controls
Privilege follows the narrowest useful boundary.
- ✓Signed manifests and packages with trusted key lifecycle
- ✓Anti-rollback and explicit entitlement/territory
- ✓Separate software, content and configuration identities
- ✓Atomic activation with protected last-known-good state
- ✓No production CDN/activation claim in public reference
Release evidence
A green demo is not a production acceptance case.

Independently scopeable products
Compose the system without collapsing product ownership.
Each product can be bought and operated independently while sharing identity, context and lifecycle contracts.

Turn the Map Content Lifecycle reference into your program architecture.
Confirm target products, vehicle and cloud boundaries, source systems, contract versions, deployment, validation and lifecycle ownership.
