Virgil Meeting E4B Adapter Bundle
This package contains lightweight adapter deltas and provenance metadata for a
local meeting-state component used by compatible Virgil deployments.
It is not a standalone model, does not include base model weights, and does not
define a public extraction API. Runtime prompting, constrained decoding,
validation, fallback orchestration, and product-specific interpretation live in
the application layer.
Contents
- Primary adapter delta.
- Guarded fallback adapter delta.
- Manifest with hashes, sizes, provenance, and the recorded quality snapshot.
- Notice file for upstream model terms.
Compatibility
The bundle is intended for runtimes that already implement the matching local
operation contract. Consumers should treat the manifest as the versioned
interface and should keep adapter loading, prompt assembly, structured decoding,
and post-processing behind the application boundary.
Quality Snapshot
The packaged contract is the A_v25 safe hybrid path. On the 100-row real-use
meeting eval, the recorded contract reached parse 1.000, non-noop kind/op F1
0.504, target-hint F1 0.553, and product score 0.351.
The fallback adapter is included for guarded recovery cases, not as the default
behavior.
Distribution Notes
Base Gemma weights are not included. Use of the upstream base model and any
derivative distribution is subject to the applicable Gemma terms. Keep the
NOTICE file with any redistributed bundle.
This artifact is intentionally minimal: it identifies what the runtime needs to
load, but the exact product contract remains part of the host application.
