Implements Spor C of post-v3.4.0 roadmap. Zero-dep harness measures CLAUDE_CODE_FORK_SUBAGENT cache-prefix preservation across 3 fork-children with identical --allowedTools at 150-250K parent context. Harness uses --append-system-prompt-file (avoids stdin buffer cap at >200K bytes) + --exclude-dynamic-system-prompt-sections (prevents per-child cache-prefix divergence from cwd/env/git-status). Companion analyser summarizes accumulated ultraexecute-stats.jsonl: percentile wall_time (p50/p90/max), total events, ISO time range. Output: JSON via --json <path> CLI shim. Result file is gitignored (*.local.md). Master-plan thresholds (<= 1.5K positive / >= 3.5K negative) gate the v3.5.0 Path C decision.
