Agent Manual Studio workflows

Workflow 1: Create a manual package
Entry condition: the loopback server is running and the loopback origin /builder/ is open.
Step 1: Review the fixed public sample chapter catalog.
Step 2: Enter a title from 3 to 80 characters.
Step 3: Enter an audience from 5 to 120 characters.
Step 4: Enter positioning from 10 to 240 characters.
Step 5: Submit Package Create.
Completion condition: the server returns HTTP 201, writes package.json, manual_package.md, and review_queue.json under output/packages/{id}/, and the browser opens /packages/{id}/.
Failure behavior: invalid values stay in the form; the server returns a bounded Korean error; no partial package directory is reused.
Next step: inspect chapters and export Markdown or JSON.

Workflow 2: Review a sample card
Entry condition: the loopback origin /review/ loads the fixed three-card public sample deck plus any local rating state.
Step 1: Choose Reveal Answer on a card.
Step 2: Read the sample answer.
Step 3: Choose Again, Hard, Good, or Easy.
Completion condition: output/runtime/review_state.json is atomically replaced and the queue shows the next due date.
Failure behavior: controls are re-enabled, the error is announced, and the prior local state remains.
Next step: review another due card or leave the screen.

Workflow 3: Export a package
Entry condition: a package detail route exists on the loopback origin.
Step 1: Choose Markdown Export or JSON Export.
Completion condition: the same local package file is returned with an attachment filename based on the validated package ID.
Failure behavior: unknown IDs return 404; invalid IDs or formats return 400; no arbitrary file path can be requested.

Workflow 4: Inspect the public preview
Entry condition: /preview/ is open without authentication on the public or loopback origin.
Pointer and keyboard path: hover or focus the motion stage to play; leave or blur to reset.
Touch path: choose Play Preview; choose Reset to return to step one.
Reduced-motion path: the button advances one static step at a time and no automatic motion runs.
Completion condition: the viewer understands input, package generation, and review queue without seeing customer, account, or payment data.
