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; orchestration still needs duplicate-worker prevention.

Active Batch

Broad generation trial is paused after self-audit.

No single-shot gate is active. The five-shot visual trial is accepted. The character-consistency workflow test is also visually accepted, but broad production should not scale until the orchestration fixes below are applied.

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	Paused until broad-run orchestration is repaired: per-shot brief/prompt trace is restored, visible character shots use actual references, identity-heavy child sessions are capped at 2 slides, and one slide/version cannot launch duplicate slide agents.

Next Decision

Repair the orchestration rules before the next production batch:

• For this project, assign at most 2 visible-character / identity-heavy slides per child session. Keep the generic workflow default at 3 for broader/non-expensive slide work.
• Start brief/orchestration work as user-visible Codex child/session threads and record their thread ids.
• Inside a child session, start one internal SubAgent / one-shot slide worker per slide; do not create long-lived reusable slide agents.
• Add a duplicate-worker guard: one slide/version must have exactly one owning worker and one prompt/image/return target set.
• Keep the quality route from this test: gpt-image-2 Advisor prompt/spec, active style master, active character registry, and visible reference images loaded before generation.
