D1 of post-v3.4.1 stabilisering. Path C (cache-warm sentinel + identical-tool parallel) is closed 2026-05-05 per Q3 experiment NEGATIVE result: median cache_creation_input_tokens = 163,903 across 3 fork-children at 186K parent context (CC v2.1.128, Sonnet 4.6). Master-plan thresholds: <= 1,500 POSITIVE / >= 3,500 NEGATIVE — NEGATIVE solidly. CLAUDE_CODE_FORK_SUBAGENT does not preserve cache prefix across identical-tool children at our context size. Path C migration is deferred indefinitely. Reassessment is appropriate when CC v2.2.xxx ships fork-cache-relevant features. Harness (scripts/q3-cache-prefix-experiment.mjs) and analyser (lib/stats/cache-analyzer.mjs) remain available for re-run.
