TAS-093: Rust-only article acceptance gate v2

[AtlantisPleb]

Summary

Strengthen the acceptance surface so the final article claim cannot turn green unless the full Rust-only Percepta closure prerequisites are actually present.

Problem

The existing acceptance and article-parity artifacts do not encode the stricter Rust-only prerequisites needed for the full article claim.

Hypothesis

A strengthened acceptance gate that requires Rust-only sources, profile completeness, parameter-ABI closure, direct model-weight proof receipts, Hungarian and hard-Sudoku reproducers, multi-million-step throughput floors, and cross-machine validation will make the final claim auditable instead of interpretive.

Target Surfaces

• psionic-eval
• psionic-research
• psionic-serve
• scripts/

Initial Scope

• Define acceptance gate v2 for the Rust-only article path.
• Add negative checks for each missing prerequisite.
• Bind the gate to the article reproduction harness and closeout audit.

Benchmark / Tests

• Gate checker tests.
• Negative tests for each missing prerequisite artifact.
• Green-only-when-complete acceptance tests.

Claim Discipline

This is the main anti-hand-wave control surface. The gate should stay red unless every required Rust-only article prerequisite is actually committed and reproducible.

Done When

• Acceptance gate v2 exists and is machine-checkable.
• The gate fails on every missing prerequisite individually.
• The gate only turns green when the whole Rust-only article path is present.

[AtlantisPleb]

Landed on main in 9e629f1 (Add Rust-only article acceptance gate v2).

What shipped:

• psionic-eval now publishes the machine-legible TassadarRustOnlyArticleAcceptanceGateV2Report schema for the Rust-only article prerequisite gate.
• psionic-serve now owns the canonical gate builder and committed report at fixtures/tassadar/reports/tassadar_rust_only_article_acceptance_gate_v2.json, plus the public checker scripts/check-tassadar-rust-only-article-acceptance-v2.sh and example cargo run -p psionic-serve --example tassadar_rust_only_article_acceptance_gate_v2.
• psionic-research now commits the operator summary at fixtures/tassadar/reports/tassadar_rust_only_article_acceptance_summary.json.
• The one-command reproduction harness is now bound to the same gate as a ninth required green component, and the runbook plus TAS docs now cite the gate explicitly.

Validation run:

• cargo test -p psionic-eval rust_only_article_acceptance_gate -- --nocapture
• cargo run -p psionic-serve --example tassadar_rust_only_article_acceptance_gate_v2
• cargo run -p psionic-research --example tassadar_rust_only_article_acceptance_summary
• cargo test -p psionic-serve rust_only_article_acceptance_gate_v2 -- --nocapture
• cargo test -p psionic-research rust_only_article_acceptance_summary -- --nocapture
• ./scripts/check-tassadar-rust-only-article-acceptance-v2.sh
• ./scripts/check-tassadar-rust-only-article-reproduction.sh
• cargo test -p psionic-serve rust_only_article_reproduction -- --nocapture
