revlm-plugin

The official channel data-plane plugins for Revlm (plugins v3 architecture):

• OpenAI: ChannelGroup.type == "openai_compatible", handles GET /v1/models, GET /v1/models/:id, POST /v1/chat/completions, POST /v1/responses, and POST /v1/responses/input_tokens.
• Anthropic: ChannelGroup.type == "anthropic", handles POST /v1/messages.

Each plugin is an LD_PRELOAD module that provides extern "C" revlm_handle_v1 (the single /v1 data-plane hook), plus the interposable upstream-prepare and model-catalog symbols. Non-matching ChannelGroup.type chains via dlsym(RTLD_NEXT).

Build the modules against the host core headers (a matching Revlm checkout or an installed RevlmCore package), then package each plugin with packaging/build-package.py. The script intentionally requires both artifacts, because production packages must contain backend/amd and backend/arm.

Revlm's multi-architecture container release also builds one image-local system package per image. It uses --system-target linux-amd64|linux-arm64 with the native module; that package deliberately contains only the image's own architecture and is never used as an upload artifact. The release Docker build expands it with packaging/install-system-package.py into the host's read-only REVLM_SYSTEM_PLUGIN_DIR layout.

See the package format for the ABI and lifecycle contract.
