Targeted repair
Regeneration is the most expensive way to fix a small mistake.
It costs the render, it costs the review of everything it touched, and it introduces new variance in shots that were already right. Repair is narrow on purpose.
01 / Inside the workflow
The blast radius problem
In most generation workflows the smallest thing you can change is the thing you generated. If the episode was generated as an episode, the smallest fix is an episode. One wrong hand in one shot costs the whole run, and the new run is not identical to the old one, so shots that were fine come back different and have to be reviewed again.
That is the blast radius, and it is why correction costs compound. Tosheo attacks it by making the unit of generation, the unit of review, and the unit of repair the same small thing.

Versioning that keeps the relationship
A repair is not a replacement that erases its predecessor. Tosheo keeps the original, the repair, the reason, the approval and which deliverable ended up carrying which version.
This matters for three separate reasons, and only one of them is creative.
- Creative
- You can go back. A repair that made things worse is reversible because the accepted original still exists.
- Rights and provenance
- The delivery manifest has to state how the delivered version was made. If the repair used a different provider or a different reference, that is part of the record.
- Economic
- Generations and repair attempts per accepted shot is a cost metric. You cannot manage it if repairs overwrite their own history.
Shot 04 is right in every way except that Kabir's hand is malformed for eleven frames as he reaches toward the keepsake.
- Wrong unit
- A region, across part of one shot
- Repaired
- That region, with the same references and treatment
- Untouched
- Shots 01 to 03 and 05 onward, all still accepted
- Untouched
- The Hindi voice track for this scene
- Recorded
- Original, repair, reason, approver, final deliverable
The episode does not re-render. The neighbouring shots do not need re-review. The audio is not re-timed. The cost of the fix is close to the cost of the thing that was wrong, which is the only sane relationship between the two.

Repair without collateral change
A repair that fixes the hand and changes the lighting has not succeeded. Repair success without collateral change is tracked as its own production-quality metric for exactly this reason.
Keeping a repair narrow is why the locked treatment from provider routing matters. Reproducing the conditions of the original generation - same provider, same parameters, same references, same canon version - is what makes a narrow repair possible at all.
Questions
Before you bring it into production
Can I replace one shot without remaking the episode?
That is the core design goal of this system, and it is the single capability that most distinguishes a production system from a generation tool. The shot is the unit of generation, review and repair, so replacing one leaves its neighbours and their approvals in place.
Will a repair look different from the shots around it?
It should not, and that is measurable rather than a matter of hope. A repair reproduces the provider, parameters, references and canon version of the original, and repair success without collateral change is one of the metrics we track. Where a repair does not match, it is rejected like any other unacceptable result.
What happens to the original when a repair is accepted?
It is kept. The delivered version is the repair, but the original, the reason for the repair and the approval chain remain part of the production record and the delivery manifest.
Do repairs count against my authorized budget?
Repairs needed because a provider failed or returned an unusable result are a Tosheo cost. Repairs that come from a change of mind are a scope change and are estimated like any other scope change. The distinction is recorded, not argued about at invoice time.
Can a subtitle or one language track be repaired on its own?
Yes. A subtitle, an audio segment, or one market variant are all repairable units. A pronunciation problem in one track does not touch the master or the other tracks, which is the practical benefit of treating languages as tracks rather than separate projects.
