• the land now type-checks sdk/: a new sdk gate, right after the site gate in orchestrator::GATES, runs npm ci, npm run build:wasm and npm run typecheck in the landing position sdk/ (hygiene::SDK_GATE_STEPS), refusing on a failed build or a type error, riding the merged-tree re-gate, skipping under --skip-tests as sdk=SKIPPED, and degrading a provably offline npm ci to sdk=SKIPPED-OFFLINE with a block of its own, so the verdict line gains sdk= after site=; the two npm gates now share run_npm_gate and supersede_offline. the land was chosen over ci/test-main.sh because only a land refuses before main moves and GitHub Actions had not run since 2026-09-19, and over the site gate step because site= would then speak for two packages. measured in a fresh lane: npm ci 1.4 s, build:wasm 17.8 s cold but 1.7 s once the site gate has built the same crate, tsc 1.0 s, the whole gate 5.05 s. proved live through the sdk row with real npm, wasm-pack and tsc: clean, red at npm run typecheck with TS2322 for a string assigned to a number in sdk/src/hex.ts, clean again once removed. ADR 0071 gains the #2080 amendment and CONTEXT.md an SDK gate entry, and workflow.md, the land-change skill and sdk/README.md say what runs and that npm test still does not. red under mutation, counts read each time: the typecheck step dropped (7 passed, 2 failed), the sdk row running the site gate (5 and 4), the sdk= field reading the site slot (7 and 2), the supersede rule reading one fixed gate (8 and 1), an offline install refused rather than degraded (7 and 2), each restored to green. a land runs the primary release loot-first, so the gate is live once those binaries are rebuilt; no migration and no format byte moves, so this owes no deploy. the workspace suite is green (4322 passed over 137 binaries, 12 ignored) (#2080) 072abcc1 · dbf3dbe6…
