## What changed
Add `ContextProfile` to `codex-guardian-context` and route synchronous and asynchronous Guardian transcript rendering through it. Move default limits, retention, formatting, and async chunked eviction into the shared crate while preserving the distinct retention policies and host-managed full/delta cursors.
Carry transcript truncation observations through `RenderedTranscript` into context composition, and derive async image collection flags from the resolved profile.
## Testing
Add a profile regression test covering distinct sync/async retention priorities, original entry numbering, omission notes, and async truncation observations. Adapt existing transcript tests to the updated input API.

## Why
Reasoning configuration changes need to retain their position and trusted provenance when model history is persisted and replayed. Client-injected history must not be able to forge these controls.
## What changed
- Add a typed `configuration_update` response item carrying reasoning effort, including custom model-defined values.
- Persist harness-authored updates with provenance and preserve them across history reconstruction, thread resume, raw response notifications, and agent forks.
- Exclude untrusted configuration updates from model history, strip client-supplied provenance metadata, and reject configuration updates supplied as turn input.
- Export the new item through the JSON and TypeScript app-server schemas and classify it in telemetry and persistence metrics.
## Testing
- Cover serialization, provenance persistence, history filtering and rollback, resume reconstruction, and injection attempts before and after restart.

## What changed
- Add typed context sections for root-conversation evidence, trusted user answers, and conversation transcripts to `codex-guardian-context`.
- Use the shared section registry when building core Guardian prompts and asynchronous Guardian V2 scoring context.
- Preserve source-role labeling while delivering authorization evidence as user-role context, and fail closed when context collection fails.
## Testing
- Cover shared section ordering and role preservation for synchronous and asynchronous targets.
- Verify trusted user answers appear exactly once as user-role input in Guardian V2 approval flows.

## What changed
- Add a reusable transcript contributor for synchronous and asynchronous Guardian context, with borrowed conversation history and request-specific configuration.
- Preserve conversation order and role or tool attribution while applying separate per-entry limits for messages, ordinary tools, and Node REPL-backed outputs.
- Make tool calls, tool outputs, and reasoning independently configurable, and expose transcript collection without requiring section composition.
- Register the transcript contributor in a process-wide default registry that retains no request state.
## Testing
- Add unit coverage for role and tool attribution, optional evidence sources, orphaned and named tool outputs, registry reuse, and request-specific entry limits.
