Flat config with two layers. Correctness (type-checked): the headline rules for this codebase are no-floating-promises / no-misused-promises (a lost promise in the agent loop is our primary bug class), switch-exhaustiveness-check (we switch over merge-extensible unions everywhere), no-unnecessary-condition, require-await, and no-explicit-any. Style (@stylistic): 2-space, no semicolons, single quotes, trailing commas, max-len 140 — the existing house style, now enforced instead of drifting between agents. vendor/ is excluded (vendored source keeps upstream style); tests relax the rules that fight test ergonomics (non-null assertions after expects, async mock signatures, non-Error throws). Code adjusted to pass: registry disposers wrap ctx.effect's promise-returning disposer behind a sync () => void (our public API), BlockAssembler gains an invariant-checking mustGet instead of non-null assertions, lastTurnNumber uses findLast, waterfall tails return Promise.resolve instead of async-without-await arrows, and the two deliberate suppressions (non-exhaustive derivation switch, unbound execute pass-through) carry justification comments. yarn lint / yarn lint:fix added.
