/**
 * Tiny-tier-only strict delegation directive (pure prompt text), riding the
 * context stack right after the agent catalog. Static prompt sections
 * measurably move capable models to delegate broad sweeps (workhorse/cheap
 * went 2/6 → 6/6 in the 2026-08-31 probe battery) but a sub-Haiku model
 * ignored the same section (qwen3.6-27b: 0/6 with it verified on the wire); a
 * <system-reminder> sits closer to the user text, where weak models actually
 * attend. Keyed and byte-stable, so it is cache-neutral; removed when a model
 * switch leaves the tiny tier (see index.ts emitDelegationSteer).
 *
 * Sibling texts (same delegation policy, separately tuned registers):
 * DELEGATE_STRICT in system-prompt/tiers/low.ts (tiny prompt) and
 * DELEGATING_WORK in tiers/mid.ts (workhorse/cheap prompt). The shared policy
 * invariants are pinned by test/unit/delegation-prose.test.ts — when editing
 * one register, keep the siblings aligned or that test will say so.
