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 That prior candidate had no matching brief/prompt and is now treated as superseded historical evidence, not as recoverable task output.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.
