cross-lang-sync

name: cross-lang-sync description: Audit Python/Rust constitutional constant synchronization across BIZRA modules. Detects drift in IHSAN, SNR, ADL Gini, Harberger, and related thresholds between core/integration/constants.py and canonical Rust sources.

Cross-Language Constant Synchronization Audit

You are the Cross-Language Sync Auditor for the BIZRA ecosystem. Your mission is to detect and report drift between the Python and Rust implementations of constitutional thresholds.

Canonical Sources

Constants to Audit

Tier 1 — Constitutional (MUST match exactly)

• IHSAN_THRESHOLD — Python: 0.95, Rust: must be 0.95
• SNR_THRESHOLD — Python: 0.85, Rust: must be 0.85
• ADL_GINI_THRESHOLD — Python: 0.35, Rust: must be 0.35
• ADL_HARBERGER_TAX_RATE — Python: 0.05, Rust: must be 0.05
• MIN_CONFIDENCE — Python: 0.80, Rust: must be 0.80 (promoted from test-local 2026-04-15)
• MAX_HARM_SCORE — Python: 0.30, Rust: must be 0.30 (promoted from test-local 2026-04-15)

Tier 2 — Operational (should match)

• STRICT_IHSAN_THRESHOLD — Python: 0.99
• SNR_THRESHOLD_T0_ELITE — Python: 0.98
• SNR_THRESHOLD_T1_HIGH — Python: 0.95
• CONFIDENCE_HIGH / CONFIDENCE_MEDIUM / CONFIDENCE_LOW
• GENESIS_CUTOFF_HOURS — Python: 72

Tier 3 — Structural (verify alignment)

• Ihsan dimension weights (8 dimensions summing to 1.0)
• Four Pillars thresholds
• PAT minting thresholds

Audit Protocol

1. Run the audit script (if available):

   python3 .claude/skills/cross-lang-sync/audit_constants.py
   

2. Manual cross-reference — Read both canonical files and compare:

   • grep -n "IHSAN_THRESHOLD\|SNR_THRESHOLD\|ADL_GINI\|HARBERGER" core/integration/constants.py
   • grep -rn "IHSAN_THRESHOLD\|SNR_THRESHOLD\|ADL_GINI\|HARBERGER" bizra-omega/bizra-core/src/ bizra-omega/bizra-resourcepool/src/

3. Check for rogue definitions — constants defined outside canonical files:

   • grep -rn "IHSAN_THRESHOLD\s*=" core/ --include="*.py" | grep -v constants.py
   • grep -rn "IHSAN_THRESHOLD\|SNR_THRESHOLD" bizra-omega/ --include="*.rs" | grep -v "use crate\|pub const\|lib.rs\|omega.rs"

4. Proofspace sweep — the ProofSpace runtime is the primary enforcement consumer; audit must verify no hardcoded copies:

   • grep -nE "MAX_HARM_SCORE|MIN_CONFIDENCE|ADL_GINI_MAX|IHSAN_THRESHOLD|SNR_FLOOR|SNR_MINIMUM|SNR_THRESHOLD" bizra-omega/bizra-proofspace/src/*.rs bizra-omega/bizra-proofspace/benches/*.rs
   • Every pub const or const in these files must either re-export from bizra_core::* / bizra_core::omega::* or fail the audit.

5. Full workspace sweep — catch constants in crates not explicitly listed above:

   • grep -rnE "^[[:space:]]*(pub )?const (IHSAN_THRESHOLD|ADL_GINI_MAX|MAX_HARM_SCORE|MIN_CONFIDENCE|SNR_THRESHOLD|SNR_FLOOR|SNR_MINIMUM|HARBERGER_TAX_RATE)[[:space:]]*:[[:space:]]*(f64|u32|Decimal)[[:space:]]*=[[:space:]]*[0-9]" bizra-omega/ --include="*.rs" | grep -v "bizra-core/src/" | grep -v "bizra-resourcepool/src/" | grep -v "bizra-node0/"
   • Any match is a rogue hardcode and fails the audit.

Output Format

## Cross-Language Sync Audit Report

### Status: [ALIGNED | DRIFT DETECTED]

### Tier 1 — Constitutional Constants
| Constant | Python | Rust | Status |
|----------|--------|------|--------|
| IHSAN_THRESHOLD | 0.95 | 0.95 | ALIGNED |
| SNR_THRESHOLD | 0.85 | 0.85 | ALIGNED |
| ADL_GINI_THRESHOLD | 0.35 | 0.35 | ALIGNED |

### Drift Details
- *(example)* If a mismatch is detected, list it here with
  `Constant: Python=X (file:line), Rust=Y (file:line)` and recommended fix.

### Rogue Definitions
[List any constants defined outside canonical files]

### Recommendations
[Specific file:line fixes needed]

Known Drift (as of 2026-04-15)

None. All Tier 1 constitutional constants are ALIGNED across Python and Rust. All downstream Rust consumers re-export from bizra_core or use the canonical bizra_resourcepool Harberger definition — verified by full workspace sweep (step 5).

Audit must include bizra-proofspace (runtime + benches) in addition to bizra-core and bizra-tests — this is the primary ProofSpace enforcement path and the highest-severity drift surface in the repo.

History:

• Phase 56: ADL_GINI_THRESHOLD drifted Python=0.35 vs Rust=0.40 — RESOLVED (Rust now 0.35).
• 2026-04-15: MIN_CONFIDENCE and MAX_HARM_SCORE promoted from test-local (proof_pyramid_e2e.rs) to canonical in both constants.py and bizra-core/src/lib.rs. Test file now re-exports via bizra_core::{MIN_CONFIDENCE, MAX_HARM_SCORE}.
• 2026-04-15: IHSAN_THRESHOLD in proof_pyramid_e2e.rs was hardcoded 0.95; patched to re-export bizra_core::IHSAN_THRESHOLD — drift-risk surface closed.
• 2026-04-15 (correction): Initial canon-promotion missed bizra-proofspace runtime copies at src/lib.rs:40-46, src/fate_proof.rs:49-55, src/receipt_chain.rs:399-401, and benches/proof_pyramid_bench.rs:154-157. All four sites now re-export from bizra_core::*. cargo test -p bizra-proofspace --lib → 42/42 pass. Audit protocol updated to sweep proofspace explicitly.
• 2026-04-15 (final): SNR_FLOOR in fate_proof.rs:61 was last hardcoded Tier-1 constant — patched to bizra_core::SNR_THRESHOLD. Audit protocol widened to cover full Tier-1 set (SNR_FLOOR, SNR_MINIMUM, SNR_THRESHOLD) and codified workspace-wide sweep as step 5.
• 2026-04-16 (receipt correction): ADL_HARBERGER_TAX_RATE was always present in Rust at bizra-resourcepool/src/lib.rs:72 as HARBERGER_TAX_RATE; the real gap was the skill's canonical-source list, not the codebase. Canonical Rust sources now include bizra-resourcepool so the audit protocol can prove its own Tier-1 set honestly.

When to Run

• After any change to core/integration/constants.py
• After any change to bizra-omega/bizra-core/src/lib.rs or omega.rs
• Before any release (part of quality gates)
• On demand via /cross-lang-sync
