## What changed
- Allow `features.guardianv2` to remain a boolean toggle or specify classifier instructions, the review threshold, reasoning effort, and action and instruction token limits.
- Add transcript controls for included sources, per-entry and total token budgets, and the number of recent non-user entries.
- Validate configured ranges and relationships, expose them in the generated config schema, and apply the resolved settings throughout Guardian v2 classification and approval review.
## Testing
- Cover boolean compatibility, configuration parsing and boundaries, config-manager rejection, and the resulting classifier request and approval decision.

## What changed
- Replace the single byte limit with token-derived per-entry and separate message and tool transcript budgets.
- Preserve the first and latest user messages, then fill the remaining budgets with recent user, assistant, and tool context while limiting retained non-user entries.
- Truncate oversized entries in the middle without splitting UTF-8 characters, and report the approximate omitted token count.
- Exclude reasoning from the default transcript sources while retaining support when it is explicitly configured.
## Testing
- Cover oversized message and tool-result truncation, user-message retention, separate tool budgeting, configured reasoning, and the resulting Guardian sampling request.

## What changed
- Represent Guardian sampling input as an ordered list of text entries.
- Send each transcript entry and approval-request delimiter as a separate input
content item while preserving the existing transcript byte limit.
## Testing
- Update transcript and sampler tests to verify entry boundaries, multi-item
request serialization, and bounded transcript behavior.

## What changed
- Add a configurable renderer that converts conversation messages, agent
messages, tool calls and outputs, and reasoning into a numbered plaintext
transcript.
- Keep only relevant readable content, including manual-approval developer
messages, while omitting media payloads, encrypted content, and unsupported
response items.
- Limit transcripts to the most recent 320 KiB without splitting UTF-8
characters.
## Testing
- Cover source selection, content filtering, tool-name correlation, and bounded
UTF-8 truncation with unit tests.
