## Validation Override

- Package size: 8 slides for this task only.
- This exceeds the current ordinary production default of 5 slides and does not change that default.
- Validation goals:
  - Confirm callback is the child session's final action after all allowed writes/checks/handoff work.
  - Observe whether child context still has margin after an 8-slide package.
  - Provide a compression-safe parent continuation surface after callback.
- User confirmation received in parent thread: production-stage default is no per-image human review; this 8-slide validation is accepted and promoted to the ordinary production-light package rule.
- Observed production metrics from user: 174K tokens, 67% context, 38m37s elapsed.
- Default ordinary production-light package size is now up to 8 slides.
- Parent verification after callback:
  - Child handoff exists and reports `complete`.
  - Expected brief, prompt, and image files exist for S-38 through S-45.
  - Exact `sNN-v1-review.md` targets are absent.
  - `slides/slides.md` recorded all eight rows as generated, then the parent promoted them to `production-pass / 8-slide validation accepted` after user rule clarification.
  - Child thread tail shows no project file writes or checks after the callback/final child response.

## Expected Versions

- S-38: expected `s38-v1` if files are unchanged.
- S-39: expected `s39-v1` if files are unchanged.
- S-40: expected `s40-v1` if files are unchanged.
- S-41: expected `s41-v1` if files are unchanged.
- S-42: expected `s42-v1` if files are unchanged.
- S-43: expected `s43-v1` if files are unchanged.
- S-44: expected `s44-v1` if files are unchanged.
- S-45: expected `s45-v1` if files are unchanged.

The child session must scan each target slide folder before writing. These expected versions are not authority.

## Callback Final-Action Rule

- The child must complete all allowed project writes, `slides/slides.md` updates, narrow required checks, and `child-session-handoff.md` before callback.
- The callback is the final child action.
- After a successful callback, the child must not write, verify, inspect, or update project files.
- The handoff should say `Callback: ready-to-send-as-final-action`; the parent callback itself is the sent receipt.

## Stop Conditions

- Any target path already exists for the resolved version.
- Required visual-system or reference files cannot be read.
- The active generation path cannot load a required visible-context image reference for an identity-relevant slide.
- The child cannot use `gpt-image-2` Advisor / host-native workflow.
- Tooling tries to call MiniMax MCP, CCPE, GPT V2, web search, or external vision/review services.
- The child reports `blocked`, `failed`, or `warning`.
- The child finishes cleanly; parent must pause for user visual confirmation before changing package-size defaults.
