Sam & Claude aa2b851748 Probe: large stable prefix yields live DeepSeek cache hit (Sam & Claude)
Short prompts don't engage DeepSeek prefix caching. Inflated the immutable prefix past the cacheable threshold (~3.7k tokens, byte-stable, COLIBRI_PROBE_PREFIX_REPEAT) + a 2s commit delay (COLIBRI_PROBE_DELAY_MS). Live run on domedog: second call served 3584/3661 prompt tokens from cache (~98% hit), cache_hit_observed=true, model deepseek-v4-flash.

Records the key-free result as manifests/2026-05-26-domedog-deepseek-cache-result.json (proof gate #2 evidence) and adds it as a colibri-contracts golden test (6 pass). No key in repo; .env stays gitignored.
