F11 off-thesis exemption budget cap with weekly telemetry

The current prompt (line 193) says 'F11 off_thesis_explore is EXEMPT from this saturation cap per S183 decage' — meaning F11 has NO cap whatsoever. Replace the unconditional exemption with a softer cap: F11 may appear up to 5 times in RECENT_ADMITS (last 14 days). At 5+ F11 admits in 14 days, return {reject: true, reason: 'f11_explore_budget_exhausted'}. Additionally, append to genesis.js a post-cycle hook that writes a single-line audit log to hypothesis_engine/data/f11_exemption_log.jsonl with {timestamp, f11_count_14d, f11_archetypes_admitted: [...]} every time a cycle completes. This preserves S183 decage intent (explore is allowed) while preventing mode collapse INTO explore.

F11 exempt admits will be bounded at 5 per 14-day window. If the engine currently runs hot on F11 (which is the risk of an unbounded exemption), this caps it. Expected hit rate of the new cap: 1-3 reject events per month if F11 was previously absorbing the saturation pressure from F1-F9.

Inspect hypothesis_engine/data/engine.db for last 60 days of admitted hypotheses grouped by archetype_family. If F11 count over any rolling 14-day window has never exceeded 4, the cap is a no-op and a logged exemption audit alone (without the cap) is sufficient — the cap is unjustified extrapolation.

Rejected by filter_score. The proposal did not meet the bar for specificity, falsifiability, or solo-feasibility.
