6.4 4-Minute Calibration Scrimmages & Zero-Knowledge Bridge

chinwag scrimmage start --duration 4m

⏳ Coming Soon (v0.2.0 · CHWG-PUB-114 · 🔒 Next Up — Core Engine): The optional Friday Syndicate Cup & PhantomVault sponsor bridge (chinwag ext install vault over the 20-byte WorkToPlayCounterBridgeV1 zero-knowledge counter firewall) is queued for v0.2.0 (Chinwag Reflex-1 p10: 2026-11-27 · p50: 2026-12-04 · p90: 2026-12-11). Track live status via /api/reality-matrix and the Chinwag Public Roadmap.

Great engineering teams need a lightweight, high-energy way to unwind at the end of a sprint while sharpening how humans and AI agents spot edge cases under time pressure.

Every Friday (or at the close of a sprint milestone), squads running The Chinwag Way can launch a 4-Minute Captionizm Calibration Scrimmage (and compete in the optional Friday Syndicate Cup).

# Launch a 4-minute Friday team calibration scrimmage in your terminal or workbench
chinwag scrimmage start --mode captionizm --duration 4m

How a 4-Minute Calibration Scrimmage Works

1. The Prompt (60 seconds): The squad is presented with a real (sanitized) architectural plot twist · a subtle concurrency race, a cursed CSS layout failure, or an absurd legacy edge case.
2. Paired Synthesis (90 seconds): Each human developer pairs with one of their configured AI agent seats (<SEAT>#<INSTANCE>) to craft the sharpest, most technically deadpan diagnosis or caption (Captionizm).
3. Blind Peer & Cross-Model Vote (60 seconds): Submissions are anonymized (BLAKE3 commitment reveal) and scored simultaneously by the squad and an adversarial cross-model judge panel.
4. Instant Payout (30 seconds): Winners earn bonus MO-GRPO Chips (◈) on the sprint leaderboard, and the winning architectural takeaway is optionally retained as a permanent team memory or tombstone.

The 20-Byte Zero-Knowledge Counter Bridge (WorkToPlayCounterBridgeV1)

For teams that connect their Chinwag workspace to PhantomVault (via the optional chinwag ext install vault extension) for Friday Syndicate Cup tournaments, Chinwag enforces a strict hardware-grade cryptographic firewall between your corporate source code and external game/scrimmage state (INV-ZK-BRIDGE-20B-01).

The only data allowed to cross from your engineering repository into the scrimmage arena is a fixed 20-byte (160-bit) zero-knowledge counter struct (WorkToPlayCounterBridgeV1) containing aggregate numeric counters and zero strings, zero file paths, zero commit hashes, and zero customer metadata:

#[repr(C, packed)]
pub struct WorkToPlayCounterBridgeV1 {
    pub epoch_week_u16: u16,          // Bytes 0..2:   ISO week counter
    pub settled_chips_u32: u32,       // Bytes 2..6:   Aggregate settled MO-GRPO Chips (◈)
    pub survival_bps_u16: u16,        // Bytes 6..8:   7-day SURV score in basis points (0..10000)
    pub clean_handoffs_u16: u16,      // Bytes 8..10:  Verified .cwcard.png handoff count
    pub tribunals_passed_u16: u16,    // Bytes 10..12: 176/176 UI + 64/64 Copy gates passed
    pub blind_team_tag_u64: u64,      // Bytes 12..20: Keyed BLAKE3-64 blinded squad tag
} // Total wire size: exactly 20 bytes (0 bytes of source code, identifiers, or PII)
