## Timeline

- 2026-06-24: Task initialized from handoff and user instruction.
- 2026-06-24: Mode recorded as `prompt and generate`, but current generation scope limited to `s05`.
- 2026-06-24: Started reusable `session-01` child-session agent `019ef77d-552b-7343-abe4-88921b35d7ea` for incremental `s05 -> s21 -> s14` testing.
- 2026-06-24: Child session wrote `s05` brief and packet.
- 2026-06-24: Started single-slide `s05` slide-agent `019ef781-1ff1-7073-80b0-3cf688104cdb`.
- 2026-06-24: Slide-agent wrote `s05-v1-prompt.md`, `s05-v1-image.png`, and `s05-v1-review.md`.
- 2026-06-24: Main session reconciled an interrupted return mismatch: the return initially claimed generation was blocked, but file/hash evidence showed the slide-agent image had already been generated and copied.
- 2026-06-24: Main session also loaded the same primary reference and produced an alternate reference-check candidate under `.codex/generated_images`; the alternate was not copied into the project.
- 2026-06-24: User identified a workflow defect: the `s05` rerun overwrote an existing broad-run `s05-v1-image.png` candidate. That prior candidate had no matching brief/prompt and is now treated as superseded historical evidence, not as recoverable task output.
- 2026-06-24: Workflow reset before `s21`: update docs and local task records first; do not reuse old child-session id; next slide execution must resolve a new unused slide version and must not overwrite existing artifacts.
- 2026-06-24: Started new `session-02` child-session agent `019ef7ca-413a-7662-9633-7fb126b7ef35` for `s21` only. It must start `Agent S-21` itself or record `runtime fallback required`.
- 2026-06-24: `session-02` resolved `s21-v2`, wrote child-session plan, `s21-v2-brief.md`, `s21-v2-slide-agent-packet.md`, and child-session handoff. It could not start a separate `Agent S-21` because no subagent/spawn tool was exposed inside the child runtime, so it recorded `runtime fallback required` and stopped before prompt/image generation.
- 2026-06-24: Started Codex thread-level child test `session-03` in local project thread `019ef7d2-1a7f-7a90-8c04-0098239dfe0f`. This restart must scan existing `s21-v*-*` artifacts and append a new version, expected to be after `s21-v2`.
- 2026-06-24: `session-03` resolved `s21-v3`, wrote child plan, `s21-v3-brief.md`, and `s21-v3-slide-agent-packet.md`, then started a separate thread-level `Agent S-21` thread `019ef7d6-3ff6-7213-b68c-fd646e39f1d2`.
- 2026-06-24: `Agent S-21` wrote `s21-v3-prompt.md`, generated/copied `s21-v3-image.png`, and wrote `session-03/returns/s21-v3-slide-agent-return.md`. No `s21-v3-review.md` was written.
- 2026-06-24: `session-03` wrote `child-session-handoff.md`; parent task now pauses for user visual confirmation before any `s14` / `s25` continuation.
- 2026-06-24: User visually accepted `s21-v3-image.png`.
- 2026-06-24: Parent authorized continuation for `s14` and `s25` in the same child thread `019ef7d2-1a7f-7a90-8c04-0098239dfe0f`. The child must start two separate one-shot slide workers, `Agent S-14` and `Agent S-25`; it must not reuse or continue `Agent S-21`.
- 2026-06-24: `session-03` continuation wrote `child-session-continuation-s14-s25-plan.md`, `s14-v2-brief.md`, `s25-v2-brief.md`, and packets for `s14-v2` / `s25-v2`.
- 2026-06-24: Child handoff records `Agent S-14` thread `019ef803-95d7-7411-8d3c-c7f2f68a32e7` and `Agent S-25` thread `019ef803-e757-7041-8f4a-fc9dfce23bbd`; both are separate from `Agent S-21`.
- 2026-06-24: Parent inspection found an additional duplicate `Agent S-14` thread `019ef803-328a-7e40-a0b0-0333c6b5fc6c` from the same child thread, using the same `s14-v2` packet and targets. This means step 2 did not satisfy the exact three-agent expectation cleanly.
- 2026-06-24: `s14-v2-prompt.md`, `s14-v2-image.png`, and `s14-v2-slide-agent-return.md` exist, but S-14 provenance is mixed: the child handoff names `019ef803-95d7-7411-8d3c-c7f2f68a32e7`, while the return/image source path records generated-image folder `019ef803-328a-7e40-a0b0-0333c6b5fc6c`.
- 2026-06-24: `s25-v2-prompt.md`, `s25-v2-image.png`, and `s25-v2-slide-agent-return.md` exist from `Agent S-25` `019ef803-e757-7041-8f4a-fc9dfce23bbd`.
- 2026-06-24: No `s14-v2-review.md` or `s25-v2-review.md` was written; review suppression behaved correctly.
- 2026-06-24: User visually accepted both `s14-v2-image.png` and `s25-v2-image.png`. This test is complete. Quality-route issues are considered repaired; the duplicate-worker defect became the target of the next carrier / worker mechanism test.
- 2026-06-24: Runtime vocabulary / default carrier rule was updated: `session` means a clean user-visible Codex child thread; `Agent` / `SubAgent` means an internal one-shot worker. Forked or inherited-context threads are not the default production carrier.
- 2026-06-24: An inherited-context S-33 attempt was paused before slide dispatch and wrote no project output; `session-04` was restarted as a clean child session.
- 2026-06-24: Started clean `session-04` child thread `019ef876-c5b2-7202-b204-774cb5fb95fd` for S-33, with review disabled and append-only output versioning.
- 2026-06-24: `session-04` resolved `s33-v2`, wrote `child-session-plan.md`, `worker-launch-ledger.md`, `s33-v2-brief.md`, and `s33-v2-slide-agent-packet.md`, then started internal `Agent S-33` `019ef87a-3aa1-75a2-a97c-de8f57e234e1`.
- 2026-06-24: `Agent S-33` wrote `s33-v2-prompt.md`, generated/copied `s33-v2-image.png`, and wrote `session-04/returns/s33-v2-slide-agent-return.md`. No `s33-v2-review.md` was written. User confirmed S-33 flow checks passed and accepted the image.
- 2026-06-24: Continued the same clean child thread `019ef876-c5b2-7202-b204-774cb5fb95fd` for S-06, with review disabled and no single-shot skeleton support.
- 2026-06-24: `session-04` continuation resolved `s06-v2`, wrote `child-session-continuation-s06-plan.md`, updated `worker-launch-ledger.md`, wrote `s06-v2-brief.md` and `s06-v2-slide-agent-packet.md`, then started internal `Agent S-06` `019ef886-8797-7243-9427-d45065fcfc47`.
- 2026-06-24: `Agent S-06` wrote `s06-v2-prompt.md`, generated/copied `s06-v2-image.png`, and wrote `session-04/returns/s06-v2-slide-agent-return.md`. No `s06-v2-review.md` was written. User confirmed second-step flow checks passed and accepted the image.
- 2026-06-24: `session-04` closed as a mechanism pass for this scope: one clean child session, two distinct internal one-shot slide workers, append-only versions, no review files, and no duplicate worker observed.
- 2026-06-24: Started R4 `session-05` clean child thread `019ef8cf-4ab1-7b41-877b-979dc25b0a76` for first package `S-02`; parent waited by workflow and read only compact handoff/status. User reported S-02 work time as 13m55s and child context as about 107K tokens.
- 2026-06-24: `session-05` produced `s02-v2-image.png`; user accepted the image. Review was disabled and no `s02-v2-review.md` exists.
- 2026-06-24: Continued the same `session-05` child thread for second package `S-03` and `S-04`; parent waited by workflow and avoided image/prompt review.
- 2026-06-24: `session-05` produced `s03-v2-image.png` and `s04-v2-image.png`; user accepted both images. Review was disabled and no `s03-v2-review.md` or `s04-v2-review.md` exists.
- 2026-06-24: User observed total `session-05` child context around 132K tokens after the second package; context usage is acceptable enough that brief ownership, not context pressure, became the primary mechanism concern.
- 2026-06-24: R4 mechanism check found that `s02-v2-brief.md`, `s03-v2-brief.md`, and `s04-v2-brief.md` were generated by the slide Agents, not by the visible child session before worker launch. Evidence: each slide return lists the brief and packet under worker-written files.
- 2026-06-24: R4 second-package handoff records a `S-04/s04-v2` sequencing warning: `Agent S-04` launched before the visible child session separately wrote and confirmed `s04-v2-brief.md` and `s04-v2-packet.md`. No collision, overwrite, duplicate worker, review file, or extra slide work was observed.

## Child Session Results

- `session-01` child-session agent: `019ef77d-552b-7343-abe4-88921b35d7ea` (deprecated / do not reuse).
- `session-01` child-session output: `s05` brief and packet only; main session started the `s05` slide-agent, so child-session-owned slide-agent launch was not validated.
- `session-02` child-session agent: `019ef7ca-413a-7662-9633-7fb126b7ef35`.
- `session-02` result for `s21`: runtime fallback required; no `Agent S-21` id; no prompt/image/return written.
- `session-03` child thread: `019ef7d2-1a7f-7a90-8c04-0098239dfe0f`; completed thread-level child mechanism test for `s21-v3`.
- `session-03` slide-agent thread: `019ef7d6-3ff6-7213-b68c-fd646e39f1d2`; generated `s21-v3` and returned successfully.
- `session-03` continuation handoff: `session-03/child-session-continuation-s14-s25-handoff.md`; records `Agent S-14` `019ef803-95d7-7411-8d3c-c7f2f68a32e7` and `Agent S-25` `019ef803-e757-7041-8f4a-fc9dfce23bbd`.
- Parent-observed duplicate worker: `Agent S-14` `019ef803-328a-7e40-a0b0-0333c6b5fc6c`; duplicate launch/provenance defect for `s14-v2`.
- `session-04` child thread: `019ef876-c5b2-7202-b204-774cb5fb95fd`; completed clean child-session mechanism test for `s33-v2` and `s06-v2`.
- `session-04` `Agent S-33`: `019ef87a-3aa1-75a2-a97c-de8f57e234e1`; generated `s33-v2` and returned successfully.
- `session-04` `Agent S-06`: `019ef886-8797-7243-9427-d45065fcfc47`; generated `s06-v2` and returned successfully.
- `session-04` result: same clean child thread continued from S-33 to S-06, but S-06 used a distinct one-shot internal worker and did not reuse `Agent S-33`.
- `session-05` child thread: `019ef8cf-4ab1-7b41-877b-979dc25b0a76`; completed R4 visual production for `s02-v2`, `s03-v2`, and `s04-v2`, but not a clean mechanism pass.
- `session-05` `Agent S-02`: `019ef8d1-188a-70c3-8a7c-4e915144a276`; worker-generated brief/packet/prompt/return, then visible child session handled host-reference generation. User accepted image.
- `session-05` `Agent S-03`: `019ef8e2-5229-72a3-93c9-16e46a87d3bf`; worker-generated brief/packet/prompt/return, then visible child session handled host-reference generation. User accepted image.
- `session-05` `Agent S-04`: `019ef8ec-8032-7de0-a8b8-0d40d456fbaa`; generated `s04-v2`, user accepted image, but child handoff records a sequencing warning around worker launch before visible-child brief/packet prewrite confirmation.

## Slide Status Summary

| Slide | Status | Notes |
| --- | --- | --- |
| `s05` | generated / local review complete, with overwrite defect recorded | `s05-v1-image.png` now points to the reference-capable rerun. Earlier broad-run `v1` candidate was overwritten during the defective workflow. Do not repeat this pattern. |
| `s02` | accepted / R4 complete | `s02-v2` image accepted by user. No review file. Mechanism note: `Agent S-02` wrote brief/packet; visible child session completed host-native generation after worker reference-attachment blocker. |
| `s03` | accepted / R4 complete | `s03-v2` image accepted by user. No review file. Mechanism note: `Agent S-03` wrote brief/packet; visible child session completed host-native generation after worker reference-attachment blocker. |
| `s04` | accepted / R4 sequencing warning | `s04-v2` image accepted by user. No review file. Mechanism warning: `Agent S-04` launched before visible-child brief/packet prewrite confirmation; no collision, overwrite, duplicate worker, or extra slide work observed. |
| `s06` | accepted / mechanism pass | `s06-v2` prompt/image/return exist from clean `session-04` continuation with `Agent S-06` `019ef886-8797-7243-9427-d45065fcfc47`, no review file. Prompt records `gpt-image-2` Advisor, style module A, and visible back/walking character refs. User accepted the image. |
| `s21` | generated / user accepted | `session-02` remains fallback evidence only. Codex thread-level child `019ef7d2-1a7f-7a90-8c04-0098239dfe0f` resolved `s21-v3`, started separate `Agent S-21` thread `019ef7d6-3ff6-7213-b68c-fd646e39f1d2`, wrote prompt/image/return, and correctly suppressed review. User accepted the image. |
| `s14` | accepted / mechanism defect | `s14-v2` prompt/image/return exist, no review file. Prompt records `gpt-image-2` Advisor, visible character refs, and style B. User accepted the image. Mechanism is not clean: duplicate `Agent S-14` threads `019ef803-95d7-7411-8d3c-c7f2f68a32e7` and `019ef803-328a-7e40-a0b0-0333c6b5fc6c` targeted the same v2 files; return/image source belongs to the duplicate thread folder while child handoff records the other S-14 id. |
| `s25` | accepted | `s25-v2` prompt/image/return exist from `Agent S-25` `019ef803-e757-7041-8f4a-fc9dfce23bbd`, no review file. Prompt records `gpt-image-2` Advisor, visible character refs, and style A adapted for dust/detail. User accepted the image. |
| `s33` | accepted / mechanism pass | `s33-v2` prompt/image/return exist from clean `session-04` with `Agent S-33` `019ef87a-3aa1-75a2-a97c-de8f57e234e1`, no review file. Prompt records `gpt-image-2` Advisor, A/D-adjacent style calibration, and visible side/front/master character refs. User accepted the image. |

## Open Decisions

- Duplicate-worker prevention remains a historical defect from `session-03`, but `session-04` did not reproduce it in a two-step sequential continuation.
- R4 formal-run produced visually accepted S-02/S-03/S-04 outputs but exposed a brief-ownership mechanism issue. Decide whether visible child sessions must write and confirm `sNN-vN-brief.md` and `sNN-vN-packet.md` before launching slide Agents, especially when no GPT skeleton expansion exists.
- Child-session launch rule is closed for this repo default: use clean user-visible Codex child/session threads for brief/orchestration work, continue the same thread only inside the approved scope, and use internal SubAgent / one-shot slide workers for each slide.
