## What changed
- Retain captured root conversation sources until synchronous preparation applies request limits. Keep asynchronous snapshots limited to the bounded messages.
- Move approval-reason truncation and tool-description escaping and truncation from composition into preparation.
- Extract synchronous image preparation and admission into `guardian-context`, preserving the prompt token cap and model context-window checks.

## What changed
Collect original retained instructions, assistant context, and verified answers before applying synchronous request limits in `guardian-context` preparation. Carry original record sizes through collection, preserving whole-record omission notices, source ordering, and host assistant-context framing.
Apply retained transcript source size checks during synchronous transcript preparation as well.
## Testing
Extend regression assertions for synchronous/asynchronous retained-context parity and equivalent verified-answer omissions when oversized records are filtered during preparation.

## What changed
Represent collected fragments with `RetainedInstructionItem`, preserving their content, semantic kind, and source. Assign retention policy when composing context: user instructions, host notices, and framing remain required, while assistant context remains optional at commentary priority.
GitOrigin-RevId: 0080f3abd0d763bd402e78da0ac1b0fa0cd7678d
## Why
Ordinary user replies can depend on preceding assistant messages. Losing those messages during compaction can leave Guardian without the context needed to interpret a reply's scope.
## What changed
- Retain original assistant messages, including commentary, with their recorded order across checkpoints and resume. Exclude compaction output from this evidence.
- Include assistant context in local and delegated reviews as untrusted context, with separate storage limits and lower budget priority than user instructions.
- Prefer assistant context preceding ordinary replies when selecting bounded root evidence, and report unavailable context without inferring what a reply refers to.
- Preserve inherited context scope and remove assistant evidence beyond rollback boundaries, including during rollout migration.
## Testing
Extend coverage for compaction and resume, checkpoint migration, queued-input ordering and rollback, role labeling, and evidence budgets that preserve user restrictions while dropping assistant context.
GitOrigin-RevId: 886189b0be29ffc3d324b56f5d0b673d6b8d84da
## Why
A delegated task can omit restrictions from the sender's user messages. Guardian needs that context when reviewing actions in the receiving thread.
## What changed
- When thread-owned Guardian context is enabled, capture up to three recent local user messages when a `send_message_to_thread` delivery from `codex_app` or `codex_tui` is accepted.
- Provide a bounded snapshot to synchronous and asynchronous reviewers, with explicit notices for unavailable evidence and a reminder that historical context does not transfer permission. Keep the snapshot out of the worker prompt.
- Retain snapshots with their deliveries across replay, compaction, and rollback, and strip them from forked agent history.
## Testing
Add coverage for reviewer-only visibility, missing sender provenance, context-budget preservation, checkpoint replay and rollback, fork isolation, and input serialization that rejects harness metadata.

## What changed
Move completed REPL response rendering into `codex-guardian-context` and register a synchronous-only `NodeReplEvidence` section. Core supplies a borrowed view of its evidence snapshot and retains responsibility for capture, storage eviction, and the delivery cursor.
Preserve the existing text and multimodal layouts, rendering bounds, omission markers, image ordering, and deduplication. Exclude evidence payloads from the rendered section's debug output.
## Testing
Adapt the existing evidence tests to exercise the shared renderer. Extend registry coverage to verify synchronous-only inclusion, rendered content, and omission of evidence payloads from debug output.
GitOrigin-RevId: eb181870558a7f2f77270dee7c17d36700f3e148
## What changed
Move bounded transcript image collection into `codex-guardian-context` and expose it through an optional `TranscriptImages` section. Update the async scorer to consume this section, preserving source filtering, image detail, omission accounting, and the existing limits of four images and 8 MiB of image URL data.
## Testing
Add coverage for source order, tool-output filtering, disabled image collection, oldest-image eviction, oversized images, and omitted-byte accounting.

## What changed
Move trusted skill rendering into `codex-guardian-context` as `TrustedSkills` and collect it through an async-only context section. Pass the collected section to the sampler, preserving the separate developer message and bounded JSON rendering. Omit skill paths from `Debug` output, exposing only their count.
## Testing
Move rendering tests alongside the shared type, covering multiple paths and escaped UTF-8 within the size budget. Extend registry tests to cover async-only inclusion, omission for empty input, section ordering, and path redaction in debug output.
GitOrigin-RevId: c0778067f19d31e693ca954aee1a7d7be8f9739a
## 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`.
GitOrigin-RevId: ee7cb4e9b9ceced70438cb58060d1a2973e1dc6a
## What changed
Move prior-review rendering and developer-message construction into `codex_guardian_context`, and route async scorer evidence through a dedicated `PreviousReviews` context section.
Validate a maximum of eight review fragments and a per-fragment byte budget equivalent to 1,000 approximate tokens. Reject oversized evidence without rewriting or dropping records, and fail closed when validation fails. Preserve authorization-version filtering and the existing developer-role delivery. Keep review contents out of debug output.
## Testing
Add coverage for count and UTF-8 byte-size boundaries, preservation of accepted fragments, async-only section delivery, and omission of review contents from debug output.
GitOrigin-RevId: 05e9f53a6405f490b2424b2491a834cd90ab24f0
## What changed
Represent denied read paths and globs with `PermissionContext` and render them through a sync-only section in `codex-guardian-context`. Keep policy resolution in the host and preserve the existing permission warning in Guardian review prompts.
## Testing
Extend registry tests to verify permission sections appear only for synchronous reviews. Extend the session reuse test to check that resolved denied paths and globs appear in both the initial review request and the next review's delta.
GitOrigin-RevId: a966a14b367f1eedb5a577f7ed74a869559ae646
## What changed
- Replace `ComposedContext` with ordered `ContextSection` values that retain section identities through transcript selection and rendering.
- Add a shared `PlannedAction` section and renderer for core synchronous approval prompts and the Guardian V2 asynchronous scorer, preserving full, delta, terminal-input, and network-request framing.
- Keep action JSON and retry reasons out of `PlannedAction` debug output.
## Testing
Update registry and transcript tests to assert section identities and source roles. Extend registry coverage to verify planned-action collection for both consumers and omission of action JSON and reasons from debug output.
