## Status

The third session / SubAgent workflow test is complete.

R3 accepted results:

- `S-33` -> `slides/s33/s33-v2-image.png`
- `S-06` -> `slides/s06/s06-v2-image.png`

R3 mechanism result:

- Clean child session: `019ef876-c5b2-7202-b204-774cb5fb95fd`
- `Agent S-33`: `019ef87a-3aa1-75a2-a97c-de8f57e234e1`
- `Agent S-06`: `019ef886-8797-7243-9427-d45065fcfc47`
- Both slide agents were distinct one-shot internal workers.
- Review files were intentionally absent.
- Prompts recorded `gpt-image-2` Advisor mode plus style and character references.
- User accepted both images.

The user will manually commit the current documentation updates. R4 should start in a new clean session after that commit.

## Rules Updated Before R4

Read these first in the new session:

```text
AGENTS.md
docs/workflows/slide-task-orchestration.md
docs/workflows/slide-task-templates.md
projects/2026-06-23-在路上/project.md
projects/2026-06-23-在路上/execution-plan.md
projects/2026-06-23-在路上/slides/slides.md
```

Key runtime rules:

- `子会话` / `session`: clean user-visible Codex child thread, created with `create_thread`; do not use forked inherited-context threads by default.
- `Agent` / `SubAgent`: internal one-shot worker owned by the child session.
- One slide Agent handles exactly one slide/version, writes one return, then becomes terminal / closed.
- Closed Agents must not be continued or reused.
- Main session production default: dispatch, wait, read short handoff, continue. Do not audit prompt / return / ledger / image details when the child reports complete with completion gate pass.
- Waiting rule: first wait 10 minutes; if incomplete, poll every 1 minute; stop routine waiting at 15 minutes total and inspect/report timeout.
- Child-session completion gate is mandatory.
- Instruction / visual review is optional and should run only when the task asks for review.
- `无 review` means no `sNN-vN-review.md`; return and handoff still record that review was intentionally suppressed.

## Completion Gate Expected From Child Session

The child session must verify and summarize:

- each target slide version was resolved by scanning existing `slides/sNN/sNN-v*-*` files;
- no target file was overwritten;
- expected brief, packet, prompt, image, and return files exist for each slide;
- review files are present or absent according to the task rule;
- each slide/version has exactly one owning Agent;
- each Agent is terminal / closed after return;
- visible-context image references were loaded when required, or generation blocked before text-only identity-critical output;
- generated project image paths and hashes are recorded when available;
- handoff includes a compact parent summary.

If any item fails, return `blocked`, `failed`, or `warning` and name what the main session should inspect.

## Slide Inventory

### Project-Confirmed Complete / Keep

Total: 11.

| Group | Shots | Notes |
| --- | --- | --- |
| Core / anchor trial | `S-01`, `S-10`, `S-46`, `S-47`, `S-51` | Accepted five-shot visual trial. `阶段五-核心单镜.md` only expands `S-10`, `S-46`, and `S-51`; `S-01` and `S-47` were included by the anchor-test package. |
| Character-consistency intake | `S-05`, `S-14`, `S-21`, `S-25`, `S-33` | These are the five shots from `阶段五-人物一致性单镜.md`. `S-05` has an overwrite workflow defect but has prompt/review/reference evidence. `S-14` image is accepted but has historical duplicate-Agent mechanism defect. `S-21`, `S-25`, and `S-33` are accepted. |
| Temporary no-single-shot-skeleton test | `S-06` | Accepted in R3 as `s06-v2`; clean `session-04` continuation and mechanism pass. |

### Generated Before But Must Be Redone

These have broad-run `v1` images but no reliable brief/prompt/review trace. They cannot prove use of the style master or active references. Keep the existing `v1` files as historical evidence only; formal production should create the next append-only version.

```text
S-02, S-03, S-04, S-07, S-08, S-09,
S-11, S-12, S-13, S-15, S-16, S-17,
S-18, S-19, S-20, S-22, S-23, S-24,
S-26, S-27, S-28, S-29, S-30, S-31,
S-32, S-34
```

Total: 26.

### Not Started

These have no slide artifacts yet.

```text
S-35, S-36, S-37, S-38, S-39, S-40,
S-41, S-42, S-43, S-44, S-45,
S-48, S-49, S-50
```

Total: 14.

## Recommended R4 Scope

Use:

```text
S-02
S-03
S-04
```

Expected new versions:

```text
s02-v2
s03-v2
s04-v2
```

Reasoning:

- They are the first unfinished consecutive shots after accepted `S-01`.
- They start real production from the beginning rather than only testing isolated character shots.
- They exercise three useful cases in one child session:
  - `S-02`: distant small traveler / environment-led human shot.
  - `S-03`: body / prop detail shot.
  - `S-04`: landscape-led no-face road shot.
- All three already have broad-run `v1` images, so append-only version handling is tested.

Recommended task settings unless user changes them:

```text
running mode: prompt and generate
review: none
completion gate: required
main-session audit: none unless child handoff reports warning / blocked / failed
child-session capacity: 3 slides
```

## R4 Test Goals

R4 should simulate formal production rather than another audit-heavy mechanism test.

Main-session expectations:

- create one clean child session;
- send the R4 packet for `S-02`, `S-03`, and `S-04`;
- wait 10 minutes before checking;
- if incomplete, poll every 1 minute up to 15 minutes total;
- when the child reports `complete` with `completion_gate: pass`, continue without opening detailed prompt / return / ledger / image files;
- only inspect details if the child returns `blocked`, `failed`, `warning`, missing completion evidence, duplicate worker, artifact collision, or user-requested audit.

Child-session expectations:

- handle all 3 assigned slides sequentially;
- resolve versions by scanning existing files;
- write one brief and one packet per slide;
- launch exactly one internal one-shot Agent per slide;
- ensure each Agent closes after return;
- write prompt and image for each slide;
- write no review files unless the task explicitly changes review mode;
- run the completion gate;
- return a compact handoff usable by the main session.

## After R4

If R4 succeeds, production does not need to remain limited to only three total shots. The next step can either:

- continue in additional 3-shot child sessions, or
- move to a broader user-approved production scope while preserving child-session completion gates and one-shot slide Agents.

The next natural unfinished sequence after R4 would be:

```text
S-07
S-08
S-09
```

because `S-05` and `S-06` are already in the keep set.

## Non-Goals For R4

- Do not invoke CCPE.
- Do not ask GPT V2 for final prompts.
- Do not call Minimax MCP or external vision/review tools unless the user explicitly changes the task.
- Do not reuse or continue R3 `Agent S-33` or `Agent S-06`.
- Do not backfill old broad-run `v1` images as if they had original prompt traces.
- Do not overwrite existing slide artifacts.
