96155eaa984c5e2bb77590cbcc5fa97943e2cae1 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 1 Jan 2026 15:12:56 +0000 Subject: [PATCH 2/2] chore: add justfile per AUTHORITY_STACK operational contract All local operations now invocable via `just `: - build, build-release: cargo build variants - test: run all unit tests - smoke-test: per ANCHOR success criteria - conformance: run valid/invalid resource constraint tests - run, check, repl: interpreter commands - demo: run fibonacci example - clean, fmt, lint: maintenance recipes - status: project overview --- justfile | 88
