+# Service Readiness
+
+`phase-memory` remains local-first, but it now exposes service-readiness
+contracts that can be used by an embedded runtime, a lightweight service, or
+external adapters.
+
+## Service Contracts
+
+`phase_memory.service.service_contracts()` returns the first service contract
+catalog:
+
+- `profile.plan`
+- `graph.import`
+- `graph.lifecycle.plan`
+- `lifecycle.apply`
+- `graph.activation.plan`
+- `package.compile`
+- `audit.query`
+- `health.check`
+
+These contracts describe request fields and response classes. They are not a
+web framework binding.
+
+## Runtime Config
+
+`RuntimeConfig` captures:
+
+- local store path
+- adapter registry
+- policy mode
+- audit sink mode
+- package compiler mode
+- semantic index mode
+- dry-run default
+- trust-zone labels
+
+The default config is local and dependency-light.
+
+## Health
+
+`health_report` emits:
+
+- adapter classes
+- config
+- node counts
+- stale memory counts
+- pending review counts
+- config diagnostics
+
+The schema is `phase_memory.health.report.v1`.
+
+## Adapter Conformance
+
+The service module includes reusable conformance helpers for:
+
+- graph stores
+- event logs
+- context package compilers
+- policy gateways
+- audit sinks
+
+External adapters should pass these helpers before being wired into a runtime.
+
+## Kontextual Delegation
+
+The first delegation envelope keeps ownership explicit:
+
+- `phase-memory` owns phase policy, lifecycle planning, and activation
+  planning.
+- `kontextual-engine` owns durable records, permission-aware retrieval, and
+  long-lived storage.
+- Boundaries exchange JSON envelopes to avoid circular imports.
+
+## Deployment Modes
+
+Supported modes:
+
+- pure library
+- CLI over local files
+- embedded runtime
+- optional service runner
+- adapter layer over external stores

+- Service contracts cover profile planning, graph import, lifecycle planning,

+  and health check.
+- `RuntimeConfig` models local store path, adapter registry, policy mode,
+  audit sink mode, package compiler mode, semantic index mode, dry-run default,
+  and trust-zone labels.
+- Health reports expose adapter availability, config diagnostics, stale memory
+  counts, pending review counts, and store counts.
+- Adapter conformance helpers cover graph stores, event logs, context package
+  compilers, policy gateways, and audit sinks.
+- `kontextual_delegation_envelope` documents the JSON boundary that avoids
+  circular imports while preserving ownership between phase-memory and
+  `kontextual-engine`.
+- `docs/service-readiness.md` documents contracts, config, health,
+  conformance, delegation, and deployment modes.
+
+Validation:
+
+- `python3 -m pytest` -> 51 passed.
