# Phase 137: Closure And Cross-Runtime Audit - Discussion Log

> **Audit trail only.** Do not use as input to planning, research, or execution agents.
> Decisions are captured in CONTEXT.md.

**Date:** 2026-04-11
**Phase:** 137-closure-and-cross-runtime-audit
**Areas discussed:** closure report shape, closure semantics, final verification scope

## Closure Report Shape

| Option | Description | Selected |
|--------|-------------|----------|
| one aggregate audit surface over the existing runtime probes | preserves one shared closure report | ✓ |
| separate ad hoc summaries in multiple docs only | too diffuse for milestone evidence | |

**User's choice:** Auto-selected recommended closure surface.

---

## Closure Semantics

| Option | Description | Selected |
|--------|-------------|----------|
| close the milestone with honest open gaps named explicitly | matches the milestone goal | ✓ |
| block closure until all runtimes are fully equivalent | stricter than the milestone contract | |

**User's choice:** Auto-selected recommended closure policy.

---

## Verification Scope

| Option | Description | Selected |
|--------|-------------|----------|
| rerun targeted service/doc slices plus the new closure audit | enough evidence for the milestone | ✓ |
| rerun the entire repository test suite | too noisy for this bounded closure phase | |

**User's choice:** Auto-selected recommended verification scope.

## the agent's Discretion

- exact audit field names
- exact wording for equivalent versus degraded surfaces

## Deferred Ideas

- live-app parity proof beyond bounded bootstrap receipts
- post-closure next-milestone selection
