Description
Forensic analysis by Recca Tsai of 95 days of ~/.claude/projects/*.jsonl logs proving two silent server-side TTL regressions: March 6, 2026 (main+sub agents mixed) and April 9, 2026 (sub-agents forced 100% 5m). Findings derive from server-authored cache_creation objects (ephemeral_5m_input_tokens, ephemeral_1h_input_tokens) that cannot be falsified by the client display layer.
Key claims
- JSONL cache_creation fields cannot be falsified by the client
- Main agent TTL never affected in 95 days
- April 9 regression is role-scoped not quota-scoped
