Bill of Quantities Schedule Ref

🛡️ The Commercial Secrecy Guarantee: If technical qualification fails (< 75.00%), the Solana smart contract permanently bars Envelope B from opening. Competitors and buyers can NEVER inspect failing prices.

⚖️ Technical Evaluator: Blinded Rubrics & Isolation Commitments

Identity-redacted proposal evaluation. Evaluators commit salted score hashes in complete isolation.

Blinded Rubrics

Acting Certified Evaluator

Target Anonymized Proposal

5 Standardized Sub-Criteria Rubrics (Total 0–10,000 bps)

1. Structural Durability & Engineering Rigor (0-2000 bps):

2. Environmental & Climate Resilience (0-2000 bps):

3. Project Timeline & Critical Path (0-2000 bps):

4. Personnel Accreditation & Track Record (0-2000 bps):

5. Quality Assurance & ISO Compliance (0-2000 bps):

Cumulative Technical Score: 90.00% (9,000 bps)

Olympic Trimmed Mean Filter >20% Pruned

The on-chain smart contract automatically drops maximum and minimum scores and permanently marks rogue evaluations deviating >20% from the median as is_outlier_flagged = true.

💰 Financial Opening & Programmatic QCBS Award Math

Envelope B unsealing gated strictly by technical cutoff (75.00%). Automated composite award calculation.

Programmatic Award

Contractor Qualification & Unsealing Status

Advance through Technical Evaluation to unseal qualified financial quotations.

Solana On-Chain Award Formula:

S_composite = (S_tech × 0.70) + ((P_lowest / P_bidder) × 10,000 × 0.30)

The smart contract verifies that the winning contractor mathematically possesses the highest composite score. Submissions with higher pricing are proportionally penalized on the financial ratio.

Commercial Secrecy Defense Enforced

Test what happens when an adversary attempts to leak or force-open Envelope B for the disqualified contractor (Rogue Builder):
