08 - Hardcode Guard V5 Audit

Verdict: HARDCODE_STILL_DANGEROUS.

Live v5 reports pass=true while writer/driver directly call planner v2, builder transitively calls v2, v4 paths use old scale guard, capability proof is object existence, NULL fingerprint rows exist, authority rows are Directus-mutable, and no-bypass checks are tautologies. Fixed eligibility-affecting lists include legacy tokens/objects, readiness gates, capabilities/verifier names, signal UNION ALL/TIER1 literal, batch 1000, runaway 1000000, old scale literal true, builder CASE, and checksum NULL-to-zero. Guard is not an authority.
