The audit ledger can also report valid integrity after protected data is modified, so the PR is not safe to merge until these correctness, availability, and audit-integrity risks are addressed. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Make ledger integrity validate event content.
verify_ledger_integrity only checks prev_hash. It does not recompute curr_hash. Also, critical_smells is not part of the hashed content, and get_ledger_entries() exposes mutable nested dictionaries and lists. A caller can modify an entry, including through report.critical_smells, and verification still returns True.

Do not use /tmp/KILL as a kill-switch control.
Any local process can create this world-writable marker and make every evaluate_collection call raise PermissionError. Use a configured path in a trusted, access-controlled directory, or remove this marker source.

Enforce the documented memory and latency limits before authorization.
The gate authorizes collections above the stated KPI targets. For example, a memory_ratio of 1.50 produces VDI 10.0 and remains ready. A latency of 40.0ms produces VDI 7.5 and also remains ready.
Make memory_ratio > 1.10 and search_latency_ms > 25.0 fail is_production_ready, or revise the documented targets to define them as non-blocking advisory limits.
