+# @ethdebug/conformance
+
+Reusable ETHDebug conformance infrastructure.
+
+This package is intentionally language- and consumer-neutral. Compiler adapters
+produce ETHDebug artifacts; consumer adapters exercise debugger implementations
+against those artifacts.
+
+Current adapters:
+
+- `bugc`: in-process BUG compiler adapter.
+- `solc`: external `solc --standard-json` adapter.
+- `soldb`: external SolDB CLI adapter.
+
+The first layer checks the contract that every compiler should satisfy:
+
+- emitted programs are valid `ethdebug/format/program` objects,
+- resources and compilations are valid when present,
+- source references used by programs resolve to compilation sources.
+
+The second layer checks real debugger consumers: tests can run a debugger,
+parse its output, and assert resources, source steps, frames, or values. SolDB
+is the first consumer backend, but the runner is not tied to SolDB. The SolDB
+adapter can materialize compiler output as a SolDB-compatible debug directory
+and then drive `soldb info resources` over it. The optional Foundry adapter
+starts a local `anvil --steps-tracing` node, deploys a compiled contract with
+`cast`, sends a transaction, and scripts SolDB's interactive REPL to assert
+source-line breakpoint set/hit behavior.
+
+External adapters are opt-in in tests:
+
+```console
+ETHDEBUG_CONFORMANCE_SOLC=/path/to/solc yarn test
+ETHDEBUG_CONFORMANCE_SOLDB=/path/to/soldb yarn test
+ETHDEBUG_CONFORMANCE_ANVIL=/path/to/anvil ETHDEBUG_CONFORMANCE_CAST=/path/to/cast yarn test
+```
+
+To run the full Solidity -> SolDB resources path, set `ETHDEBUG_CONFORMANCE_SOLC`
+and `ETHDEBUG_CONFORMANCE_SOLDB`. If `anvil` and `cast` are on `PATH`, the
+SolDB breakpoint test runs as well; the executable paths can be overridden with
+`ETHDEBUG_CONFORMANCE_ANVIL` and `ETHDEBUG_CONFORMANCE_CAST`.
