Execution Plan

Current Medium Branch

  • Branch: MV shot-image production for later video assembly.
  • Format: 16:9 horizontal.
  • Production mode: image assets first; video generation/editing remains manual or semi-manual until explicitly automated.
  • Prompt ownership: Codex owns final image prompts; GPT intake is source specification, not final prompt.

Current Execution Focus

Prepare the execution base, not the full MV.

Immediate focus:

  1. Build and validate the character anchor board.
  2. Build and validate the style anchor board.
  3. Use both anchors in a small visual test package.
  4. Only after tests pass, expand into broader shot production.

Materialization Targets

Target Required Output Status
Character anchor board Main 16:9 board on shallow gray-white background accepted v2
Character transparent slices Front full body, side full body, back full body, walking side, walking back accepted v2-from-anchor set
Character labels Short identity, clothing, prop, and boundary labels pending
Style anchor board 16:9 dark-gray board with A/B/C/D samples accepted
C style retest Dark muddy puddle / broken star reflection sample accepted
Shot test package S-01, S-10, S-46, S-47, S-51 accepted

Small-Batch Strategy

Do not generate all 51 shots first.

Round 1 uses five shots because they test the system's biggest risks:

Shot Why It Is In Round 1 Anchor
S-01 Opening landscape: proves world-before-person and main A composition. A
S-10 Steel canyon: proves city pressure without tech/UI drift. B
S-46 Muddy starlight: proves the soul image and C repair. C
S-47 Night road fire: proves restrained near-fire transition after C. D
S-51 Final wide: proves distant fire, no victory, no gathering, person remains small. D

Round 1 success means these are true:

  • The traveler stays recognizable without becoming a portrait subject.
  • A/B/C/D feel like one MV, not four unrelated styles.
  • C is no longer sunrise/pretty reflection and has clear muddy starlight.
  • D is warm but not camping, gathering, or victory.
  • The output can support later prompt batching without rewriting the visual system.

Current Round

  • Round: R2 five-shot trial preparation.
  • R0 completed: intake cleaned; project execution files initialized.
  • R1 completed so far: v2 main character anchor accepted; identity lock approved for slice generation; five transparent slice candidates generated and rejected due identity drift from v2.
  • R1 completed: v2 main character anchor accepted; v2-from-anchor transparent slice set accepted.
  • R1 completed: C style retest accepted as style-anchor-c-repair-v1.png.
  • R1 completed: common style anchor board accepted as style-anchor-board-v1.png.
  • R2 completed: S-01 generated once and accepted by user.
  • R2 completed: user waived intermediate prompt review for S-10; S-10 generated once and accepted by user.
  • R2 completed: S-46 generated once and accepted by user.
  • R2 completed: S-47 generated once and accepted by user.
  • R2 completed: S-51 generated once and accepted by user.
  • R2 completed: five-shot visual trial generated and accepted by user.
  • R3 character-consistency workflow test completed: s21-v3, s14-v2, and s25-v2 generated through the Advisor / visible-reference path and accepted by user. Quality route is usable; duplicate Agent S-14 remains a historical mechanism defect from this run.
  • R3 third-round workflow test completed: session-04 generated s33-v2 and s06-v2 through a clean user-visible child session plus internal one-shot SubAgents. Both images were accepted by user; review files were absent as requested; no duplicate-worker defect was observed in this two-slide scope.
  • R4 completed visually with mechanism warnings: clean child session 019ef8cf-4ab1-7b41-877b-979dc25b0a76 generated s02-v2, s03-v2, and s04-v2; user accepted all three images and review files were absent as requested. Mechanism is not a clean pass because brief/packet files were written by slide Agents rather than prewritten by the visible child session; S-04 also has a worker-launch sequencing warning.
  • R5 brief-ownership test completed: clean child session 019ef907-16b7-7a43-9924-227892aa62d3 generated accepted s07-v2, s08-v3, and s09-v2 with child-owned brief/packet before worker launch for successful outputs. s08-v2 remains incomplete transport-failure evidence and was retried append-only as s08-v3.
  • Package-size trials completed through a user-authorized 4-slide package. session-07 produced accepted s11-v2, s12-v2, and s13-v2 with observed context 157K and elapsed time 30m5s. session-08 mechanically completed s15-v2 through s18-v2, but s16-v2 failed visual acceptance because it did not achieve 横向大远景,路从画面一侧切向远方,人物极小 and was too similar to s15.

Active Batch

Polling-based process trial is complete. Broad generation waits for the next user decision after R6 notification/wakeup test design.

No single-shot gate is active. The five-shot visual trial is accepted. The character-consistency workflow test is visually accepted for S-21, S-14, S-25, S-33, S-06, S-07, S-08, S-09, S-11, S-12, and S-13. R4 images for S-02, S-03, and S-04 are visually accepted but remain a mechanism-warning run because child-session brief ownership did not match the desired boundary. R5 successful outputs passed the child-owned brief/packet rule. S-16/s16-v2 is not visually accepted and should be redone later as append-only repair.

Open Decisions

Decision Default
Character source face Current stage does not use the real face; use a 50-year-old traveler based on the defined character system.
Character board size 16:9 page, shallow gray-white background.
Character board scope MVP can start with front/side/back full body plus half-body state; full version should add walking side/back and prop breakdowns.
Style board scope MVP one-page A/B/C/D board; C should be marked as repaired / accepted.
Full shot production Wait for next user decision after R6 notification/wakeup test. Current default route: per-shot brief/prompt trace restored, visible character shots use actual references, child sessions may handle up to 3 slides by default unless explicitly overridden, clean user-visible child sessions for orchestration, visible child writes brief/packet before worker launch, internal one-shot SubAgents for slide work, one slide/version has exactly one owning worker, and child sessions perform the completion gate before handoff.

Next Decision

R6 notification/wakeup test:

  • Replace polling with a notification/wakeup mechanism if the current Codex tools support it: the main session sends the task and exits, then the child session completion activates or wakes the main session.
  • Do not simulate notification by hidden parent polling. If no real activation/wakeup tool exists, report that as a mechanism blocker.
  • Use R6 to redo S-16 as append-only s16-v3 or the next unused version.
  • Required S-16 visual correction: horizontal extreme wide shot; road cuts from one side of the frame toward the distance; traveler is extremely small; result must clearly differ from S-15.
  • Keep the quality route: gpt-image-2 Advisor prompt/spec, active style master, active character registry when needed, and visible reference images loaded before generation.
  • Keep the brief ownership rule: the visible child session writes and confirms sNN-vN-brief.md and the slide-agent packet before launching a one-shot slide worker.
  • Keep append-only retry behavior: incomplete outputs such as s08-v2 remain historical evidence and retries use the next unused version.
  • Keep the duplicate-worker guard: one successful slide/version must have exactly one owning worker and one prompt/image/return target set.
  • Keep main-session production behavior lightweight: read child handoff by default after notification/wakeup, and inspect details only on warning/blocked/failed.
