TAS-184: Clean-room weight causality and interpreter ownership gate

[AtlantisPleb]

Summary

• prove that admitted interpreter behavior comes from Transformer forward-pass
  computation and turn that into one ownership verdict

Roadmap Position

• Phase: Phase 7. Close single-run posture, state discipline, and weight ownership
• Sequence: article-gap closure after TAS-156A
• Owned-route boundary: any canonical article route referenced here means the psionic-transformer-based route established by TAS-156A / TAS-160, not a reintroduced mixed implementation spread across model or runtime crates.
• Claim posture: necessary for article-equivalent closure, but not sufficient by itself to widen public capability claims

Description

• build the interpreter-in-weights conformance matrix over the declared article
  breadth envelope
• audit the canonical route for:
  • forward-pass sufficiency
  • route purity
  • hidden host-side execution substitution
  • no external oracle dependence
  • preprocessing shortcuts that collapse the real compute
  • route drift
  • no runtime-owned control flow
  • helper-module or import mediation that changes where the work lives
  • cache or retrieval layers that silently own the decisive step
  • no cache-owned control flow
  • cache-ownership exclusion
  • artifact-lineage-to-behavior closure
  • weight perturbation sensitivity
  • causal scrubbing and intervention behavior:
    • zeroed or randomized weight subsets
    • clamped attention heads
    • removed layers
  • computation-locality characterization:
    • localized
    • modular
    • or diffuse
• publish one computation mapping report that states:
  • where the program representation lives
  • where state lives
  • how control flow is realized
  • whether those mappings remain stable across runs
• widen direct no-tool proof from demos to the declared generic suite
• combine all of that into one interpreter-ownership gate

Why This Matters

• correct outputs alone do not prove article-equivalent ownership in the
  weights

Primary Surfaces

• psionic-transformer (canonical owned article-route base for this issue)
• psionic-models
• psionic-runtime
• psionic-eval
• psionic-research
• psionic-provider

Validation

• conformance matrix
• clean-room causality audit
• generic direct-proof suite
• weight perturbation report
• causal scrubbing / intervention report
• computation mapping report
• locality / modularity characterization report
• ownership gate checker

Claim Discipline

• Keep machine-legible boundaries explicit; partial progress must not be presented as full article equivalence.
• Preserve typed refusal, fallback, blocked, and suppressed posture where closure is still incomplete.
• Keep public language bounded to the declared article envelope rather than implying generic arbitrary-program closure from a partial green result.

Done When

• one interpreter-ownership gate exists and is green

[AtlantisPleb]

Implemented TAS-184 and pushed it to main in 134519b.

What landed:

• added the canonical TAS-184 interpreter-ownership gate report in psionic-eval, including generic direct-proof review, breadth conformance, route-purity audit, computation mapping, perturbation sensitivity, and the top-level ownership verdict
• added the eval example, research summary/example, provider receipt projection, and the dedicated checker script
• updated the blocker matrix, acceptance gate, downstream TAS reports/summaries, and the related docs/audit so the frontier now advances to TAS-184A
• regenerated the committed TAS artifacts under fixtures/tassadar/reports/ and the affected runtime bundles
• tightened the provider receipt test to validate against the committed report instead of re-proving the full ownership gate on every run

Validation:

• cargo test -p psionic-eval article_interpreter_ownership_gate --no-run
• cargo test -p psionic-provider article_interpreter_ownership_gate_receipt_projects_report -- --nocapture
• cargo test -p psionic-research article_interpreter_ownership_gate_summary -- --nocapture
• bash scripts/check-tassadar-article-equivalence-acceptance-gate.sh
• direct jq gate checks on the committed TAS-184 ownership report and summary

Issue is ready to close; remaining frontier is TAS-184A.
