feat: standalone sixg-bench deployment with tiered optional packages

[Copilot]

Turns the workspace into a clone-and-run bench. Core tier has zero native dependencies; ONNX inference, Python plots, and Level-2 baseline CSVs are opt-in.

Tier model

Tier	Flag	What's added
Core	(default)	All 11 crates, 9 experiments, Validate checks
Baselines	--baselines	Level-2 CSV comparisons (Liu TSP 2018, srsRAN, NIST)
Plotting	--plotting	Python matplotlib scripts for all experiment categories
ONNX	--onnx	Real ort-backed sentence-transformer (swaps simulation stub)

New: sixg-bench CLI binary (src/bin/bench.rs)

sixg-bench list                   # experiment registry with tier labels
sixg-bench run exp_001            # run one experiment (delegates to pre-built example binary)
sixg-bench run --all              # run all 9 experiments
sixg-bench run exp_009 --json     # structured JSON output for notebooks/CI
sixg-bench validate               # all Validate impls wired directly from crate deps
sixg-bench validate --baselines   # + Level-2 baseline experiment
sixg-bench info                   # shows which tiers are compiled in

Exit code is non-zero on any failure — usable in CI pipelines.

install.sh

• Checks for cargo; installs via rustup if absent
• cargo build --release with appropriate --features based on flags
• --onnx: guides model file placement (models/all-MiniLM-L6-v2.onnx), sets SIXG_ONNX_MODEL
• --baselines: sets SIXG_BASELINES=baselines/
• --plotting: pip install -r requirements-plot.txt
• Prints summary table of active/skipped tiers

Cargo feature flags

Added to workspace Cargo.toml:

[features]
baseline-comparison = ["sixg-phy/baseline-comparison"]  # already existed in 6g-phy
onnx    = ["sixg-ai/onnx", "sixg-semantic/onnx"]        # gates real ort inference
plotting = []                                            # compile-time marker

6g-ai and 6g-semantic gain an onnx feature flag. The existing deterministic OnnxModel simulation remains the default; real ort::Session is the intended swap behind #[cfg(feature = "onnx")].

Docker

• Dockerfile — multi-stage (rust:1.79-slim builder → debian:bookworm-slim runtime), core tier
• Dockerfile.onnx — adds libonnxruntime layer
• docker-compose.yml — three services: bench, bench-baselines, bench-onnx

docker run --rm ghcr.io/j143/6g sixg-bench run --all

Python plotting (scripts/plot_*.py)

• plot_phy.py — path loss vs distance, BER vs Eb/N0
• plot_mac.py — Jain fairness index, HARQ rounds vs SNR
• plot_isac.py — DFRC Pareto frontier (CRB vs capacity, with Liu TSP 2018 overlay)
• plot_semantic.py — compression ratio vs task success, channel estimator NMSE

CI additions (.github/workflows/ci.yml)

• matrix-features — builds and tests with "", baseline-comparison, plotting (three-way matrix)
• docker-build — builds Dockerfile on every PR; pushes ghcr.io/j143/6g:latest + SHA tag on merge to main

error: consider using sort_by_key
...

Fixed in commit 603c93f:

1. crates/6g-core/src/nrf.rs — both sort_by(|a, b| b.capacity.cmp(&a.capacity)) calls replaced with sort_by_key(|b| std::cmp::Reverse(b.capacity)) as clippy suggested.

2. Dockerfile / Dockerfile.onnx — base image bumped from rust:1.79-slim to rust:1.82-slim. The is_none_or method in digital_twin.rs was stabilized in Rust 1.82, so the older image couldn't compile it. The local clippy (1.94) also explicitly prefers is_none_or over map_or(true, ...), so the code stays as-is and the Docker image is the thing that needed updating.

Fixed in commit 2cc6980. is_multiple_of on unsigned integers was stabilized in Rust 1.87 (tracking issue #128101), but the Docker image was rust:1.82-slim. Bumped both Dockerfile and Dockerfile.onnx to rust:1.87-slim — the code stays idiomatic and local clippy (1.94) also prefers is_multiple_of over the % == 0 alternative.
