| # Alpino-e4b-v02 |
|
|
| Alpino-e4b-v02 is the **frozen A.9 AOOE-governed PEFT adapter** for Alpina content operations. This checkpoint is the final evidence-bearing v0.2 release; any further GRPO belongs to the v0.3 lineage. |
|
|
| ## Frozen checkpoint |
|
|
| - Base: `google/gemma-4-E4B-it` |
| - Base revision: `ee0ef6023621cff504d758262d4e04895a5af4a2` |
| - A.9 checkpoint: `alpino-e4b-v02-controller-escalation-32032090932/grpo-v5/adapter` |
| - A.9 training run: `32032090932` |
| - A.9 source commit: `ff507984dd11a5c33ea9e5c1dbaea4e853d87f84` |
| - Training artifact: `9289791005` |
| - Training-time adapter parameter checksum: `0c68b19cdbf8523c7bd57e2869e945a7a9df1511d3e07f711e95d33298af2c7e` |
| - Serialized `adapter_model.safetensors` SHA-256: `43c3a132e0621066febf4d9fe0bd7f2301b6247543d8614e0dd24338d13b29cd` (computed from the frozen Modal checkpoint at publication) |
|
|
| A.9 performed a real weight update from A.8 while loading **no held-out dev or immutable benchmark data**. Its strict training-only gate reached **8/8 symbolic conformance**, including **4/4 unsafe `abstain + escalate`** and **4/4 cross-entity `link_existing`** cases. |
| |
| ## Held-out development promotion |
| |
| Run `32035764957` evaluated the frozen A.9 adapter with **no weight updates** and before immutable-v2 was opened: |
| |
| - Raw: **5/6** symbolic conformance |
| - AOOE: **6/6** symbolic conformance |
| - Promotion gate: **PASS** |
| |
| The decisive unseen unsafe case remained non-conformant in Raw but became a governed **`abstain + escalate`** under AOOE. |
| |
| ## Immutable benchmark v2 |
| |
| Run `32041360569` evaluates **24 frozen unseen cases**, four each for inspect, create, edit, cross-entity, publish, and unsafe/ambiguous behavior. No tuning is permitted after reveal. |
| |
| | Metric | Raw | AOOE | |
| | --- | ---: | ---: | |
| | Valid transitions | **16/24** | **20/24** | |
| | Total tokens | 40,575 | 11,320 | |
| | Tokens / valid transition | 2535.9 | **566.0** | |
| | Unsafe mutations | **1** | **0** | |
| | Correct abstain + escalate | **0/4** | **4/4** | |
| | Valid transitions / PFLOP proxy | 43.81 | **196.31** | |
| |
| AOOE improves validity from **16/24 to 20/24**, reduces token workload by **72.1%**, and increases valid transitions per decoder-PFLOP proxy by **4.48×**. |
| |
| Class-level AOOE validity: inspect 4/4, create 3/4, edit 4/4, cross-entity 1/4, publish 4/4, unsafe/ambiguous 4/4. |
| |
| The remaining v0.3 target is **cross-entity reasoning**. A.9/v0.2 is frozen and must not be modified to chase that benchmark gap. |
| |
| ## Governance boundary |
| |
| The ontology/compiler/SHACL runtime is part of the system. The adapter alone is not the governed agent: AOOE supplies the execution boundary that turns model decisions into constrained state transitions. Publication and other side effects remain behind explicit runtime authority. |
