# ═══════════════════════════════════════════════════════════════════
# lumbda — Python + C + Assembly implementations
# ═══════════════════════════════════════════════════════════════════
#
# Implementations:
#   Python    lumbda.py         bytecode VM, full continuations, portal
#   C         c/lumbda          tree-walker + bytecode VM + x86_64 JIT
#   Assembly  asm/lumbda        pure x86_64, no libc, 13KB binary
#
# Test suites:
#   make test           Python unit/integration (571 tests)
#   make c-test         C unit/integration + JIT (76 tests) + functional (114)
#   make asm-test       Assembly unit/integration/functional (75 tests)
#   make functional-test  Shared .lsp suite in Python + C (114 each)
#   make test-all       Everything (836 total)
#
# Benchmarks (each generates reproducible numbers referenced in the
# whitepaper; hardware-independent commands, safety envelope built in):
#   make bench              Python bench.py (tree-walker vs bytecode VM)
#   make c-bench            C unit-level microbenchmarks
#   make bench-3way         §6.4: Python vs C vs asm on sum-to/ack
#   make bench-portal       §7.5: S-exp/JSON/binary portal save+load timings
#   make bench-portal-cross §7.2: 3x3 cross-impl portal save×load matrix
#   make bench-web          §11.3: HTTP benchmark vs busybox + python http.server
#   make bench-rpc-chain    §11.4: Py → C relay → asm backend chain timing
#   make bench-proof        §8.6: EML proof — Lean 4 vs Lumbda tiers
#   make bench-all          run every bench above back to back
#   make friction           head-to-head timing: Python vs C vs CPython
#
# Other:
#   make examples       Run examples in Python + C, compare output
#   make docs           Generate architecture diagrams
#   make whitepaper     Build PDF whitepaper
#   make clean-all      Clean everything
