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.

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.
