v1.0.0 Legacy Outcome Ledger

Status: resolved for the promoted v1 stable scopeRoadmap revision: v1-r3

Every compatibility surface below has a named owner and a recorded outcome. The Core and stable React outcomes are part of the promoted v1 contract; WebMCP outcomes remain explicitly experimental.

ID	Surface	Current replacement	Required 1.x decision	Evidence still required
CA-1X-LEGACY-001	ActionRegister.registerEffect()	registerGuard() or registerObserver()	retain-1x: documented dynamic-role convenience API; effectKind remains mandatory	verify:v1-core-migration; Core type/runtime coverage
CA-1X-LEGACY-002	HandlerConfig.blocking	explicit scheduling and errorPolicy	retain-1x: exact normalization in resolveHandlerConfig() through 1.x	verify:v1-core-migration; Core parity coverage
CA-1X-LEGACY-003	generic register() role	registerGuard, registerResult, or registerObserver when a specific phase is intended	retain-1x: generic result registration as the default handler API	verify:v1-core-migration; public type snapshot
CA-1X-LEGACY-004	WebMCP beforeExecute	afterExecute	experimental remove: deprecated post-commit alias is removed outside the stable v1 promise	WebMCP/React negative type test and adapter regression
CA-1X-LEGACY-005	WebMCP errorMode: 'result'	errorMode: 'structured'	experimental remove: ambiguous alias is removed outside the stable v1 promise	webmcp-error-mode.type-safety.test.ts, package/export consumer evidence
CA-1X-WEBMCP-001	WebMCP React hook on @context-action/react/tools	@context-action/react/webmcp	experimental: isolated experimental subpath	verify:react-webmcp-isolation, package/export consumer evidence
CA-1X-LEGACY-006	internal void executor	canonical result dispatch path	remove: unused _performDispatch() is removed; dispatch() delegates to _performDispatchWithResult()	Core focused regression evidence

No row may be silently removed. A future change must state the owner and target version, update this outcome, and link immutable evidence before expanding or contracting a stable surface.
