## Prior state

Miyazaki had closed one company, but it was unresolved whether its repairs were reusable capability or a one-off chain.

## Failure or pressure

A second closure cannot prove generalization if it still requires packet-specific Machine source change.

## Observations

- Second-company outbound Reality was observed at 08:52 JST.
- The 08:55 Context reported zero Human decisions, looks, manual actions, and Human-carried cross-lane messages.
- Direct Sales Production remained CURRENT on the existing repaired head.
- A CSD-specific Machine replay commit was still required.

## Hypotheses

- Miyazaki repairs created reusable capability with materially lower closure cost.
- Full Objective Runtime generalization is not yet proven.

## Interventions

- Repeated the P1 frozen path for a second company while retaining the existing repaired Product head.

## Outcomes

- Capability reuse and closure-cost reduction are grounded: **PARTIAL_COMPOUNDING**.

## Unknowns

- Whether a third company closes without packet-specific Machine source change remains unknown.
- Exact Miyazaki Human lane-hop and artifact-shuttle counts remain unknown.

## Next verification

- Observe whether a third company can close without packet-specific Machine source change.

## Why it matters

This keeps reusable capability visible without rewriting the required CSD-specific replay into proof that Objective Runtime generalizes to arbitrary packets.
