## Completed Slides

| Slide | Version | Worker id | Status | Image SHA256 |
| --- | --- | --- | --- | --- |
| S-16 | `s16-v3` | `019ef9c2-58c3-7000-a799-1b3f321f988a` | complete | `FD496F13C2C376EEE09B6D3792F8C4B83A38ED8A09D5E88B0B4EC8EB5D8F66E8` |

## Version Resolution

- Resolved version from folder scan: `s16-v3`.
- Existing files at preflight included `s16-v1-image.png`, `s16-v2-brief.md`, `s16-v2-prompt.md`, and `s16-v2-image.png`.
- Preflight found no existing `s16-v3-*` files.

## Completion Gate

- Session collision check: pass. `session-09/` did not exist before creation.
- Session folder shape: pass. Created `session-09/packets/` and `session-09/returns/`.
- Append-only / no overwrite: pass. `s16-v3` targets were absent before writing.
- Child-owned brief before worker launch: pass. `projects/2026-06-23-在路上/slides/s16/s16-v3-brief.md`.
- Child-owned packet before worker launch: pass. `projects/2026-06-23-在路上/tasks/2026-06-24-character-consistency/session-09/packets/s16-v3-slide-agent-packet.md`.
- Worker output files present: pass. Prompt, image, and return exist.
- Review suppression: pass. `projects/2026-06-23-在路上/slides/s16/s16-v3-review.md` is absent.
- Worker ownership: pass. Exactly one worker was launched for `S-16/s16-v3`.
- Duplicate worker: none observed in this child session.
- Worker-written file boundary: pass. Worker return lists only prompt/image/return as written files and states brief/packet were read-only inputs.
- Reference handling: pass. Worker return records Image 1 / Image 2 / Image 3 were visible in worker context before generation.
- Character handling: pass. Character identity image references were intentionally not used because this is a distant landscape-led shot and the traveler should be too small for identity detail.
- External service boundary: pass. No Minimax MCP, CCPE, GPT V2, or external review/vision service was called.

## Prompt / Generation Evidence

- `gpt-image-2` mode check result: `mode=B-or-C`; `recommendation=host-or-advisor`; `garden_mode_enabled=false`; `has_api_key=false`; `model=gpt-image-2`; `env_flag_value=(unset)`.
- Effective generation path: Mode B host-native `image_gen`.
- Garden/API expected: no.
- Host-generated source path: `C:\Users\wangq\.codex\generated_images\019ef9c2-58c3-7000-a799-1b3f321f988a\ig_06f101a7d5bda671016a3bd84678148191b4006b0c80a4b060.png`.
- Copied project image path: `projects/2026-06-23-在路上/slides/s16/s16-v3-image.png`.
- Image dimensions: `1672x941`.
- Image size: `2611631` bytes.
- Image SHA256: `FD496F13C2C376EEE09B6D3792F8C4B83A38ED8A09D5E88B0B4EC8EB5D8F66E8`.

## Reference Roles

- Image 1: `projects/2026-06-23-在路上/visual-system/style/style-anchor-board-v1.png` as accepted style calibration board; Module A is the positive style direction.
- Image 2: `projects/2026-06-23-在路上/slides/s15/s15-v2-image.png` as negative contrast against repeating S-15 composition/person-scale relation.
- Image 3: `projects/2026-06-23-在路上/slides/s16/s16-v2-image.png` as negative contrast against failed S-16 v2.
- Character reference images: not loaded by design; the traveler is an extremely small coordinate and identity detail should not drive the shot.

## Review Mode / Result

- Review mode: none / intentionally suppressed.
- Review result: skipped by task rule.
- Review file absence confirmed: `projects/2026-06-23-在路上/slides/s16/s16-v3-review.md` does not exist.

## Agent Lifecycle

- Worker id: `019ef9c2-58c3-7000-a799-1b3f321f988a`.
- Lifecycle: one-shot, terminal / closed after return.
- Worker must not be continued or reused for repair, retry, or another slide.

## Context Usage

- Child-session context usage: not visible to this child session.
- Parent/user observation field: pending external observation if needed.

## Problems / Repairs Needed

- None at workflow completion-gate level.
- Visual acceptance remains a parent/user decision because review is disabled and no external vision/review tool was authorized.

## Parent Summary

`session-09` completed R6 Phase 1 for `S-16/s16-v3`. The session used append-only output, child-owned brief/packet before worker launch, exactly one internal one-shot worker, host-native `gpt-image-2` Advisor generation, no review file, and no duplicate worker. The image hash is `FD496F13C2C376EEE09B6D3792F8C4B83A38ED8A09D5E88B0B4EC8EB5D8F66E8`.

## Parent Inspection Recommendation

Parent should wake from the callback, read this handoff first, then inspect `s16-v3-image.png` for visual acceptance against the repair requirement. Detailed prompt/return inspection is only needed if the parent wants to audit the image-generation trace or if the user rejects the visual result.

## Callback Status

- Callback required: yes.
- Callback target: `019ef9b5-cc39-7a42-91b1-f9b0852dc95e`.
- Callback should be sent only after this file exists.
