# 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.
## Active Batch
No multi-shot prompt batch is active yet.
No single-shot gate is active. The five-shot visual trial is accepted.
## 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 | Deferred until anchor tests are accepted. |
## Next Decision
Decide the lightweight broad-production flow for the remaining non-generated shots, including whether to skip per-shot review and generate missing shots in sequence.
