## What changed
Apply the 512-token approval reason cap in `guardian-context` when composing synchronous full and delta reviews, before request budget enforcement. Remove truncation from the requesting host and preserve exact action JSON.
## Testing
Extend the planned-action budget test to cover long approval reasons in both synchronous presentations, verifying that optional tool descriptions can be omitted without changing action arguments.

## Why
Contextual fragments and extension-owned world-state sections currently return strings, limiting them to text content.
## What changed
- Return `ContentItem` from fragment bodies and rendering, preserving classification and attribution. Apply text markers only to `InputText`; pass other content through unchanged.
- Allow extension prompt and world-state contributions to carry typed content, and preserve media in context-window hints.
- Hash non-text world-state fragments by their serialized content and role while retaining the existing text hashing behavior.
- Add shared content-to-tool-output conversion that preserves image references, image detail, and audio.
## Testing
Add coverage for typed world-state hashing and preservation of image content and attribution. Expand code-mode output tests to cover input text, output text, file-backed and inline images, and audio.

## What changed
Introduce `TranscriptRecord` and `PreparedTranscript` to retain attributed transcript text through preparation and composition. Cache rendered content, byte counts, and token estimates, refreshing them when text or framing changes.
Keep JSON records structured during budget recovery so truncation replaces only `text`, preserving metadata, field order, and framing without reparsing serialized JSON. Preserve whole-entry truncation for line transcripts and update synchronous and asynchronous consumers to use the preparation API.
## Testing
Expand coverage for cached estimates and delivery with escaped text, Unicode, and large payloads; metadata and framing preservation during recovery; and stable asynchronous history prefixes in both line and JSON formats.

## What changed
Represent host-verified tool metadata as `TrustedTool` in `codex-guardian-context` and collect it through an async-only context section. Route Guardian v2 sampling through that section while preserving separate developer-message delivery and the 512-token rendering budget. Omit tool metadata from debug output.
## Testing
Move the rendering-budget test into the shared crate, extend registry coverage for async-only collection and debug redaction, and narrow the scoped approval test to messages tagged `guardian.trusted_tool`.

## Why
Guardian authorization reviews need host-verified `request_user_input` answers to
remain aligned with thread history across compaction, resume, and rollback.
## What changed
- Record verified question-and-answer pairs in retained thread context when
`GuardianThreadContext` is enabled, and source both local and delegated Guardian
review evidence from that context.
- Preserve complete answer records within the evidence budget. Mark authorization
context incomplete when records are unavailable or oversized, and defer cached
fast approvals in that case.
- Keep the existing runtime-only answer path for threads that do not enable the
thread-owned context.
## Testing
- Cover answer retention through compaction and resume, removal after rollback,
source-call eviction, oversized answers, delegated review evidence, and legacy
behavior.

## 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.

## What changed
- Add the `codex-guardian-context` crate for assembling structured context shared by synchronous Guardian review and asynchronous scoring.
- Preserve transcript entry roles and original byte counts, and let section contributors declare shared or consumer-specific scope.
- Collect applicable sections in registration order, skip optional sections, and fail the collection when required evidence is missing.
- Provide UTF-8-safe prefix/suffix truncation with approximate omitted-token accounting.
## Testing
- Cover scoped registry collection, ordering, optional sections, required-evidence failures, truncation markers, and UTF-8 boundaries.
