3.1Modifier and Assets Delivered that do not match the Leg A turn

The mistake

Modifier or Assets Delivered misdescribes the milestone's Leg A turn: deferred_asset or revision on Leg A turn 1, none as a modifier, a bare extension for a filename, or a deferred file no row lists. Only the last fails the task.

Do this instead

Set each modifier from what its Leg A turn does to delivered work, and list each file handed over at that turn by full filename, never the deliverable.

Example 7Visual Learning · 4 Leg A turns

What is wrongMilestone 9, the deferred_asset row for Leg A turn 2, reads Assets Delivered: .html, the deliverable's extension. The file that turn hands over, bourgery_legend_pages.pdf, is on no milestone.

Leg A turn 1 asks for deltoid_plate_study.html from eighteen images. Leg A turn 2 hands over bourgery_legend_pages.pdf, the one deferred file.

Where it shows

Milestone 9Leg A turn2assets delivered.html
The Bourgery keys come from the delivered legend pages
Every one reads Assets Delivered: .html, the deliverable's own extension.

What it should have been

Milestone 9Leg A turn2assets deliveredbourgery_legend_pages.pdf
The files their own Leg A turn hands over, or empty: never the deliverable.

How it breaks the standardThe .html on those rows is the extension of deltoid_plate_study.html, the deliverable, not a file the user hands over. The file Leg A turn 2 hands over, bourgery_legend_pages.pdf, sits on no row, so a user simulator replaying them has no record of when it arrives. A deferred file missing from Assets Delivered fails the task.

The rule it breaksQC spec · Milestones - Continuation Criteria & Assets Also fails where a deferred asset was handed over during the conversation but is absent from assets_delivered

Example 8Small Business & Personal Docs · 3 Leg A turns

What is wrongMilestones 7 and 8, on Leg A turn 1, read deferred_asset and revision, with Assets Delivered: .mp4. Leg A turn 1 is always opening, and handbook.mp4 comes with it.

Leg A turn 1 attaches index.html, Vantol.pdf and handbook.mp4 together, and asks Model A to reconcile “a festival message and a runtime record” and complete the runtime section.

Where it shows

Milestone 7Leg A turn1modifierdeferred_assetassets delivered.mp4

Milestone 8Leg A turn1modifierrevisionassets delivered.mp4

The opening prompt. handbook.mp4, the only .mp4 in the inputs, is in the folder from the start.

What it should have been

Milestone 7Leg A turn1modifieropeningassets deliveredindex.html, Vantol.pdf, handbook.mp4
Milestone 8Leg A turn1modifieropeningassets deliveredindex.html, Vantol.pdf, handbook.mp4

How it breaks the standardLeg A turn 1 asks for milestone 7's work, and handbook.mp4 is in the folder before Model A starts, so nothing is deferred. Milestone 8's corrections fall within the response to that same turn, and a revision changes work delivered at an earlier Leg A turn. A bare .mp4 names no file.

The rule it breaksGuidelines · 6.3 Modifiers opening: The first turn and any later turn that adds a new requirement without touching work already delivered. Leg A turn 1 is always opening.

Example 9Creative & Media · 4 Leg A turns

What is wrongMilestones 1 and 4 read Modifier: none, which is not one of the four modifiers. Both should read opening.

Leg A has four turns. Leg A turn 1 asks for the walkthrough; Leg A turn 4 asks for every check, in order, in the reply, and touches no file.

Where it shows

Milestone 1Leg A turn1modifiernone
What the library actually contains is read from the screenshots rather than assumed from a generic folder copy.
Milestone 4Leg A turn4modifiernone
Every point at which the user is told to stop is gathered into one place, in order, with what passing and failing look like.

What it should have been

Milestone 1Leg A turn1modifieropening
Milestone 4Leg A turn4modifieropening

How it breaks the standardThe value none is not one of the four modifiers. Leg A turn 1 is always opening, and Leg A turn 4 asks for a list in the reply, changing neither walkthrough, so it is opening too. A wrong modifier costs points.

The rule it breaksGuidelines · 6.1 What a Milestone is Made of? One of the four in section 6.3. This turn is the milestone's Leg A turn.

Catch it in your own task

Read Modifier and Assets Delivered beside the Leg A prompts: Leg A turn 1 is opening, and each deferred file sits on the Leg A turn that hands it over.

Where the correct guidance is written

Section titles as they print, so you can search for them in the document.

Guidelines · 6.1 What a Milestone is Made of?

Modifier: What this turn does to work that already exists. One of the four in section 6.3. Assets delivered: Files handed over at this turn, or empty.

This turn is the milestone's Leg A turn.

Guidelines · 6.3 Modifiers

opening: The first turn and any later turn that adds a new requirement without touching work already delivered. revision: Something already delivered changes.

Leg A turn 1 is always opening.

QC spec · Milestones - Continuation Criteria & Assets

Also fails where a deferred asset was handed over during the conversation but is absent from assets_delivered, or is listed but missing from input_files/.
Why it matters

Both fields describe a Leg A turn: the modifier says what it did to work Model A had already delivered, and Assets Delivered lists the files the user handed over with it. You steer Model B by them in Leg B, and a user simulator replaying the milestones reads them to know what each turn changes and what arrives when. A wrong label misdescribes the task: a revision that revises nothing, a deferred file that was in scope from turn 1, a file handed over at a later turn that no row lists, so a replay has no record of it to hand over. Most of these cost points. The last one fails the task outright, because the QC spec requires Assets Delivered to list every deferred file.
