Policy dates and changes

Policies change, and the date on the page is the first thing to check. Many state a last-updated or effective date; this register keeps that date beside the day it was read. From 1 source page, read 2026-09-25; no maker pays to be listed.

Fig. 1 The stages are the order this primer reads a policy in; the quotes below are examples from the register.

Policies change, and the date on the page is the first thing to check. Many state a last-updated or effective date; this register keeps that date beside the day it was read.

Several texts say that continued use after a change means acceptance, and that notice may only be given for material changes. For a production, a rule can change mid-season.

When a label here changes, the statement keeps its identifier and takes the new value, so a citation to the old reading still resolves.

The dates in this register range from pages last updated in 2024 to pages changed in September 2026. A date far in the past is not a sign of neglect on its own; it can mean the rules have simply not needed to change. What matters is reading the current page before relying on a quote, and noting the date you read it.

2The making side of the policy

Policy wording in “Policy dates and changes” meets production here; SceneMixer's pages describe its side like this:

It is a property of the character, written once in the voice description, and it covers every line they speak. What changes line by line — mood, pace, a word under stress — goes in the delivery note in brackets at the start of that line.

Character consistency in AI short drama means one character keeps the same face, the same wardrobe and props, and the same art direction across the dozens to hundreds of shots in a series.
