What is BFT-33?
BFT-33 is the sovereign governance protocol that gates every important decision in SOV33. It consists of:
- 33 voters — 11 per quorum, 3 per OWEM, 4 lineages per OWEM group
- 5 OWEM groups — compliance, defense, intuition, voice, general
- 4 lineage groups — qwen, llama, deepseek, mistral (diversity via decorrelation)
- Free-MAD aggregation — weighted sum of votes (no majority conformity)
- 23/33 quorum — minimum to bind a decision
- (F+1)-robustness per OWEM group (F=10 byzantine fault tolerance)

Cross-lane Verification
The BFT-33 council was verified by Claude Code (MEOK Labs) on 12 Jul 2026 with a real vote:
"Is the sovereign care floor at 0.95?" → 9 ALLOW, 6 REJECT → ALLOW wins (Free-MAD: +3)
Per SOV33_OWEM_REALITY. The sovereign brain (compliance OWEM) knew 0.95. Oracle voters hallucinated 0.92 sometimes. This is why sovereign-trained experts matter — they catch cloud-brain errors.
How Free-MAD Works
Free-MAD (Byzantine Fault Tolerant median absolute deviation) is the aggregation method. Each voter:
- Casts a vote: ALLOW, REJECT, or ABSTAIN
- Has a weight (default: 1, can be weighted by reputation later)
- Outputs are SIGIL-anchored for audit
Aggregation: weighted sum. ALLOW > REJECT → ALLOW wins. Tie → abstain (escalate).
Real Vote (12 Jul 2026, 11:43 UTC)
Question: "Is the sovereign care floor at 0.95?"
= ALLOW ·
= REJECT ·
= no-vote
| Per-OWEM tally | ALLOW | REJECT | Verdict |
|---|
| compliance | 3 | 0 | ✅ SOV brain knew |
| defense | 2 | 1 | mostly right |
| intuition | 3 | 0 | predicted yes |
| voice | 0 | 3 | Oracle said fixed value |
| general | 1 | 2 | Oracle hallucinated 0.92 |
| TOTAL | 9 | 6 | ✅ ALLOW WINS (Free-MAD: +3) |
Honest observation: The sovereign brain (compliance OWEM) knew 0.95. Oracle voters hallucinated 0.92 sometimes. This is why sovereign-trained experts matter.
Byzantine Fault Tolerance
BFT-33 holds against up to 10 byzantine voters (F=10). The architecture:
- (F+1)-robustness per OWEM group — even if 10 voters lie, the decision holds.
- Cross-lineage decorrelation — a single model family can't dominate.
- SIGIL chain — every vote is signed; tampering is detected.
- Care-floor on outputs — voters can't lie about the care floor.
The Collusion Stress Test
(From the MEOK Labs lane, 12 Jul 2026.) The realistic adversary: colluders farm trust on easy rounds then defect together as a bloc.
| honest | colluders | first defection | sustained (captures/15) |
|---|
| 6 | 1 | HELD | 0 |
| 3 | 4 | captured | 2 (then flagged) |
| 2 | 5 | captured | 8 (then flagged) |
| 1 | 6 | captured | 15 |
Honest reading: Once colluders reach ~half the quorum they win the first defection round (classic BFT bound). But reputation decays + flags them within a few rounds, so sustained capture collapses. The real defense is upstream: diverse-lineage sourcing makes it hard to assemble ≥half a quorum from genuinely distinct lineages.
The Stack
- Identity — Ed25519 keys per voter
- Reputation — trust scores, decay, flags
- Diversity — attested across lineages (qwen/llama/deepseek/mistral)
- Vote — each voter casts ALLOW/REJECT/ABSTAIN
- Aggregate — Free-MAD weighted sum
- SIGIL — every step hash-chained + signed
Care-floor (0.95) gates every step. Below-floor output is vetoed before it returns.
