# Gate evidence pack — G1–G5 *Assembled 2026-08-19 at engine `8e0af26`. This pack leads with what it does NOT prove, on purpose: the recurring failure mode across this build was a selected number becoming the headline, and every instance was caught only by looking. A pack that names its limits first cannot be read as overclaiming — and it is the version that survives a bank's security review rather than merely passing ours. Numbers reproduce from the committed gold + the local corpus (mirrored to the private bucket).* ## Bounds and honest limitations (read first) - **G3 real-event volume is DEFERRED to real-customer data (project decision, 2026-08-19).** 438 real delegation events against a 2,000 target; the normalized-dataset target (≥10,000) is met at 18,450. The 2,000 was always a proxy for corpus richness bought from ourselves; the flywheel (customer-exported bundles, never background telemetry) supplies real volume once a design partner runs the loop. "Deferred to real-customer data", not "not met". The 25%-non-code G3 amendment is parked with it. - **Customer-domain *enforcement* is now shown on three frameworks (A3); customer-domain *observe-sampling* is ADK-only.** customer-service + financial-advisor were observed/scored on ADK; **CrewAI and LangGraph are additionally enforced live on a customer-domain (travel-booking) workload** — real delegation, a held `payments.transfer` denied live, offline-verifiable, no divergence (`docs/A3-FRAMEWORKS.md`). Bound that remains: those two are *configured* crews/graphs, not scraped third-party apps (crewAI-examples target an old API; LangGraph apps are heterogeneous) — a real third-party customer-domain app on a non-ADK framework is a design-partner activity. G1/G5 *derivation-quality* numbers remain ADK-observed. - **The G1 hold-out over-provision metric rests on 13 clean rows.** The express hold-out has 43 rows but only 13 survive the truncated/degenerate exclusion; the unused-scope and over-provision figures are computed on those 13. Small sample. - **The finance-advisory pack was curated from the very traces it is scored on.** financial-advisor shows 100% curated because we wrote its pack from its own tool set — that is onboarding, not a blind test. The honest out-of-sample curation number is customer-service (0% → 100% after curation) and the day-0 coverage on datasets the catalog never saw (§G5, and the BFCL/hermes/ToolACE out-of-sample numbers). - **No live payment denial.** Enforce is proven live single-agent and across a chain, but the specific "a booking agent's `process_payment` is denied live" run was not done (21-agent app, low marginal value). The deriver holding `process_payment` until `--grant payments.transfer` is pinned offline (`tests/test_onboarding.py`), not shown live. - **L3 (the LLM proposer) was never built.** Its trigger — a domain whose day-0 path cannot produce a confident curated grant — was never met: on the two customer domains measured, L2 (catalog + curation) resolved everything. The architectural finding (templates are a code-agent artifact; the catalog generalises) is settled; L3 stays deferred until a real gap appears. - **All sampling is Haiku-class** except the two live Sonnet enforce runs. Ceilings derived from Haiku over-exploration may be looser than a frontier model needs (a small frontier calibration slice is planned). - **The onboarding wall-clock was measured by the builder, not a naive operator.** The ≤1h / ~minutes figure (G4/G5) inherits expert bias: I knew the vocabulary and the tools. A genuinely naive onboarding — the true G4 number — is a design-partner activity that solo work cannot manufacture. The judgement points are real; the *time* is a floor, not a representative user's. ## Summary | Gate | Criterion (short) | Status | Headline (see bounds above) | |---|---|---|---| | G1 | Derivation works on real tasks | **MET** (on 13 clean hold-out rows) | benign-deny 0.0, unused 5.8%, escalation 0 | | G2 | Protects real projects (enforce) | **MET** (ADK customer-domain; live) | 21/21: 0 benign blocks; over-reach 8,783/8,783; injection 0 widened; live single + chain; Haiku ≡ Sonnet | | G3 | Data flywheel / volume | **DEFERRED** (real events, project decision) / MET (datasets) | 438 real events (target parked) · 18,450 / 10,000 dataset rows | | G4 | Production grade | **NEAR-COMPLETE** | packaged onboarding ≤1h MET; SDK/CLI + runbook + internal review done; graph-UI + service-mode outstanding | | G5 | Day-0 story | **MET** (out-of-sample) | held-out app: safe day-0, 100% curated in minutes | ## G1 — derivation works Hold-out (project-level, express held out; **13 clean rows**), chain scoring: **benign-deny 0.0 · unused-scope 5.8% · over-provision 3 · escalation 0** (thresholds ≤2% / ≤20% / esc 0). `python -m attenu_derive.eval.g1 --holdout express --check` ## G2 — protects real projects - **Enforce (offline, 21 projects incl. 2 ADK customer-domain):** 0 benign blocks; 32 role-violation over-reaches correctly blocked. `python -m attenu_derive.eval.enforce --all` - **Adversarial over-reach:** 8,783 / 8,783 = **100%**, scope-class 100%, 0 misses. `python -m attenu_derive.eval.adversarial --all` - **Task-string injection:** 43,128 poisoned variants, **0 widened, 0 escalations** (24 correctly narrower). `python -m attenu_derive.eval.injection --all` - **Live, single agent (Haiku + Sonnet):** a real customer-service agent denied mid-run on a held scope; denial contract observed; ledger anchored. `docs/LIVE-ENFORCE.md`. - **Live, delegation chain (Haiku):** analyst `{web.fetch}` ⊂ coordinator, denied `web.search` mid-chain; ledger anchored across the chain. `docs/LIVE-ENFORCE.md` (chain section). - **Structural, not model-dependent:** Haiku ≡ Sonnet — enforcement does not inherit the model's judgment. (Bound: both are ADK.) ## G3 — data flywheel - Real corpus: **438 delegation events / 599 rows / 21 projects × 4 frameworks**. The ≥2,000 real-event target is **DEFERRED to real-customer data** (project decision, 2026-08-19): 2,000 bought from ourselves was a proxy; real volume arrives via the flywheel — **customer-initiated evidence-bundle export, never background telemetry** (the custody story is the thing a bank buys). The 25%-non-code amendment is parked with it. - Normalized datasets: **18,450 rows** (BFCL + hermes + ToolACE; target ≥ 10,000 — MET). - Versioned corpus + eval harness gate every release in CI (G1 + adversarial + injection gates + corpus lint). MET. ## G4 — production grade - **Onboard in ≤ 1 hour:** MET — travel-concierge to 100% curated in minutes following `docs/ONBOARDING.md`. - Threat model, denial contract, strike policy, ledger anchoring (ADR-14): filed and tested. - **Packaging (Phase A1):** installable wheel + `attenu` CLI (`onboard`/`coverage`/`verify`) — installs into a clean env with no source tree; onboarding re-measured **through the packaged path** at ~1s (`docs/OPS-RUNBOOK.md`). - **Internal security review** vs the 5 threat-model invariants: all pass, 2 trust-boundary concerns with mitigations + Phase-B/C actions, labelled internal (`docs/SECURITY-REVIEW.md`). External review is Phase C. - **Perf:** `Deriver.propose` p50 0.038 ms / p95 0.074 ms / max 0.178 ms over real events (budget <50 ms); model path N/A (L3 never built). - **Ledger contract for the console (2026-08-19, slice 1 / Plan A):** held ≠ denied is now ON the ledger (`disposition` on every deny, in the model-facing denial, across all 12 adapters); products have an identity before a key (`attenu init` → `.attenu/product.json`, per-process boot id, assigned chain ids); the spool sink carries the ingest idempotency key; inside a product the anchor is signed with a **product-local Ed25519 key** and verified with the public key only (`attenu verify --pubkey`) — the HMAC test signer survives only outside a product and is labelled `attenu-anchor-TEST`. Repro: shim `python tests/test_core_v02.py`, `python tests/test_sinks_identity.py`, `python tests/test_adapters_contract.py`; engine `python -m pytest -q tests/test_disposition.py tests/test_product.py tests/test_run_adk_enforce.py tests/test_cli.py`. - **Delegation-graph UI and service mode** live in the optional Attenu console (https://attenu.io): the graph with denials by disposition and the verified mark (integrity · monotonicity · containment against the product's public key), evidence download, and Decisions. The open engine needs none of it; `attenu demo` produces a real anchored ledger with no model and no key. - **Control with integrity (2026-08-19, slice 2):** every change to what a product may do (grants, declared tools, policy) is a **signed config revision** — hashed, parent-chained, verified before a runner applies it, refused beyond the product's **ceiling** and on conflict (last-known-good stays); the cloud's revisions are signed by the Attenu signer the engine trusts offline; `attenu config` / `attenu ceiling`; the console shows "what I decided and what changed" with diffs and signatures. **Custody options:** product-local Ed25519 key (default) or **KMS** (`attenu init --anchor kms`; ES256; the key never leaves the HSM; auditors verify with `ECDSAP256Verifier`, no cloud SDK) — stub-tested until an AWS account exists. **Out-of-band anchoring** (`AnchorScheduler`) for long-running apps. **Evidence report** (`attenu report`, the console's Report button): a printable page rendered from the bundle + verification — the three checks, the anchor key, the chain as tree + table, denials in plain words, how to re-verify. **Demo depth:** `attenu demo --scenario fanout` (9 agents / 18 tools / every disposition / a strike revocation) and the real 21-agent travel-concierge run live as a 3-level chain. Two real bugs found by the richer app and fixed RED→GREEN (ADK transfer-back treated as a delegation; the enforce runner's sub-agent requests lacking their own descendants). G4: what remains for "production grade" is a hosted deployment and the slice-3 surface. ## G5 — day-0 story A brand-new app held out of all training (travel-concierge) gets **safe** derivation from the shipped kit alone: all payment tools withheld, unknowns fail-closed, reads granted heuristically — shadow-ready with zero unintended-payment risk. Curation then takes it to 100% with money tools held pending an operator grant. `docs/ONBOARDING.md`; `tests/test_onboarding.py`. Out-of-sample catalog coverage on public datasets the catalog never saw is the corroborating number (BFCL/hermes/ToolACE, `catalog.coverage`). **Operating cost (measured, A2c):** across the 3 onboarded apps, **23 tools, 7 (30%) required an operator judgement call**, 70% mechanical scaffold confirmations. The judgement calls are front-loaded on the tier-2 tools a bank *wants* a human deciding (payments, mail held `requires_grant`), so the curation burden scales with an app's **distinct sensitive tools, not its traffic**, and day-0 is safe before any of it. Pinned ≤50% by a test (`tests/test_onboarding.py`). ## Reproduce everything `python -m pytest -q` runs the full suite including the **injection + adversarial CI gates** and the **corpus lint** (schema-drift guard). `python -m attenu_derive.corpus.lint` → 0 violations.
