nomograph/pipeline v5.4.0 Changed: - rust-cli image: Rust toolchain floor 1.93 -> 1.94. Unblocks crates whose MSRV moved to 1.94 (immediate driver: wasmtime 46 in extension). The check job runs `cargo clippy -- -D warnings`; 1.93->1.94 clippy delta canaried clean on muxr + synthesist (0 new lints). Fail-closed gate: a stray lint can only stall a bump MR, never redden main. - hygiene gate no longer forbids AGENTS.md -- the portable, committed agent-onboarding file (dunn.dev tracks it in cycle/, othala/). nomograph now matches that convention. .claude/ stays forbidden. Reaches direct-include consumers on a v5.4.0 bump (un-reds runes); bundle intra-catalog hygiene pins remain at v4.3.0 (deliberate gate baseline).
