bigtable/Same content as bigtable/AGENTS.md — this file exists so GitHub Copilot / Copilot Workspace picks up the module-scoped guidance via its own discovery path.
See AGENTS.md for the canonical instructions. In short: before editing files under bigtable/internal/transport/**, bigtable/internal/session/**, bigtable/debugview/**, bigtable/table_shim.go, or bigtable/session_*.go, read the specs under bigtable/docs/specs/ that match the layer being touched.
