Adapter Reliability Conformance

Every platform adapter must satisfy the same ref/action contract. The macOS adapter is the first implementation, but the tests are written against PlatformAdapter semantics so Windows UIA and Linux AT-SPI can reuse the same expectations.

The reusable command-path helper lives in tests/conformance/ref_action_contract.rs. The executable smoke harness in src/tests/conformance.rs uses it with a mock adapter; future Windows and Linux fixtures can call the same helper with real adapter-provided refs.

Required Gates

Area	Required behavior
Snapshot refs	Refs are depth-first, snapshot-scoped, and explicit snapshot IDs resolve directly
Strict resolve	A ref resolves only when identity still matches; stale refs return STALE_REF
Ambiguity	Multiple plausible matches return AMBIGUOUS_TARGET, never an arbitrary click
Actionability	Ref actions check live visibility, stability, enabled state, supported action, policy, and editability before dispatch
Wait recovery	wait --element can poll the latest session refmap when no snapshot is pinned, honors the caller timeout while resolving, and reports the last observed predicate state
Session latest scope	Commands that omit --snapshot read and write only the active session's latest refmap
Explicit snapshot scope	Passing --snapshot <id> resolves that pinned snapshot even when the caller omits the original session
Trace	--trace <path> writes JSONL diagnostics outside stdout and is best-effort unless strict
FFI parity	FFI ref actions use strict resolve and actionability checks before adapter dispatch

Adding Windows or Linux

Add adapter-specific integration fixtures, but keep expected errors and JSON shapes identical. Prefer semantic platform actions first (AXPress, UIA Invoke/Value/Selection patterns, AT-SPI actions). Coordinate input is a lower confidence fallback and must remain explicit in policy or command choice.
