Gnosis Morph Bench

Live window into the Zer0pa lab. Benchmark methods are useful now, with live Indus replay blockers kept visible.

What This Is

Morph-Bench is a Gnosis benchmark-method lane: neutral route scoring, null metrics, stability battery, deterministic replay, and explicit Indus replay blockers.

gnosis-morph-bench is the benchmark-first methods lane of the Gnosis extraction program. It owns neutral route scoring, permutation-null metrics, a five-mode stability battery, deterministic replay, and SHA-256 reference-freeze helpers — without owning Indus or cuneiform scientific verdicts. Domain corpora connect through admitted adapters; the Indus Phase 4 v1 adapter is the first in-scope family.

Headline metric (repo-custody, clone-reproducible): 37 passed pytest in a clean Python 3.11 venv + byte-equality cross-environment smoke (macOS 3.11.15 ↔ Linux/RunPod 3.11.13) + 0/6 forbidden-monorepo-pattern lint hits + 9/9 ADAPTER_CONTRACT_v1 MUST-clause coverage. Evidence path: artifacts/blind_clone/ and tests/. Live Indus Phase 4 measured values (NMI 0.5793, Sigma 5.65, Jaccard 0.4351, Replay 3/3) are source-authority citations only — see docs/PROMOTION_READINESS.md trust boundary.

Honest blocker: Live Indus Phase 4 reproduction is blocked on admitted Phase 3c manifest access (Blocked-1); heavy-data release policy for image-bearing assets is open (Blocked-3). The synthetic smoke is what runs end-to-end today. See ## Readiness below and docs/PROMOTION_READINESS.md.

Repo Identity

Readiness

Honest Blocker

Live Indus Phase 4 reproduction is blocked on admitted Phase 3c manifest access, and heavy-data image-bearing release policy remains open.

What We Prove

• The neutral benchmark contract (BenchmarkManifest) round-trips cleanly through load_manifest / evaluate_route / freeze_reference / deterministic_replay / leave_fraction_out / the four added stability modes.
• The Indus Phase 4 v1 adapter satisfies every MUST clause of docs/family/ADAPTER_CONTRACT_v1.md, enforced by tests/test_adapter_contract_coverage.py.
• The forbidden-pattern lint catches the hidden-import / path-coupling patterns named by the adapter contract, self-tested via a positive control in tests/test_forbidden_patterns.py.
• The smoke and replay outputs are byte-identical across macOS and Linux at the documented Python 3.11 floor — verified end-to-end through fresh-clone install, see artifacts/blind_clone/.

What We Don't Claim

• That the live Indus Phase 4 measured values have been reproduced from repo custody. They have not. Live rerun is blocked on admitted Phase 3c manifest access (Blocked-1). Those values are source-authority citations, not Morph-Bench-proven values.
• That the synthetic smoke path constitutes proof of any live finding.
• That the heavy-data image-bearing asset release is unblocked. It is not; Blocked-3 (heavy-data release policy) remains open. See ## Readiness and docs/PROMOTION_READINESS.md.
• That the cuneiform benchmark family is in scope for the v1 adapter contract. It is explicitly deferred to a separate future contract once the first real Indus replay lands.
• That this repo carries any descriptor, kernel, image-preprocessing, or domain-verdict ownership. Those belong to other Gnosis lanes.

Upcoming Workstreams

Open work across four categories. "Useful now, improving continuously" — every item here is surfaced honestly, not an apology.

Operations / External Dependency

• Blocked-1 — Phase 3c manifest admission: live Indus Phase 4 rerun from repo custody cannot proceed without an admitted Phase 3c feature manifest JSON with SHA-256. Owner-gated. When clear: produces artifacts/replay/indus_phase4_live_<date>.json.
• Blocked-3 — Heavy-data release policy: image-bearing benchmark payloads cannot enter the repo until the release boundary is written (which asset classes, under what terms, storage location and size bound). Owner-gated. When clear: produces DATA_POLICY.md §Image-Bearing Release appendix.

Active Engineering

• Cuneiform benchmark family adapter: deferred to a separate future contract per current scope decision; no active engineering until Blocked-1 live rerun lands and the v1 adapter is validated against a second source family.
• Smoke byte-reference re-freeze: local housekeeping only; re-run smoke and commit the new byte-reference when convenient. Not a promotion gate.

Research-Deferred — Investigation Underway

(none currently — all research surface is defined by the v1 adapter contract and the 5-mode stability battery)

Zero-Base Scientific Thinking — GPD Research and Planning Pending

(none currently — the Phase 04 cuneiform contract is the next planned GPD unit; not yet initiated)
