SUC-CCM-03 · Screen: SCR-CCM.04 (Media Upload Dialog — parameterized: image)

ReturnUrl context

Current returnUrl: /author-course/
Fallback: / when returnUrl is empty.
Propagation: all state-toggle links carry returnUrl. Save → returnUrl. Cancel → returnUrl + &sub_cancelled=1.

Sub-flow context

SUC-CCM-03 · Invoked by (Backoffice Portal): UC-CCM.01 (Author Course Content), step 6 — «include» entry from the "Add Content → Image" action on the Content Editor.
Precondition: user has edit rights on the course; the selected Content Item has no content linked yet.
Success: image saved and bound to the lesson → Course Editor updates the lesson structure to show the new image (UC-CCM.01 step 7).
Cancel after upload (AF 5A): the uploaded file is deleted; the lesson item remains empty as before.
Reuse from the asset library is not part of this dialog — it is handled at SCR-CCM.26 "From Library" tab before entering this SUC.

Screen spec: SCR-CCM.04 (image case)

• Regions: Context header · Upload area · Resource metadata · Dialog actions
• context_header: read-only · default from param.context_header · data_ref: course name + lesson path
• file_input: required · visible when upload_state == idle · accept: JPG, PNG, WebP (SS-CCM.02) · max size TBD (design phase)
• upload_progress: visible when upload_state == uploading · range 0–100
• resource_title: required · min length 1 · default = original filename · visible when upload_state == complete · data_ref: CourseDraftResource.title
• resource_description: optional · visible when complete · data_ref: CourseDraftResource.description
• duration_estimate is defined on this shared screen but scoped to resource_type == video only — not shown for the image case
• "Require completion tracking" toggle: called out in SUC-CCM-03 main flow step 4 (not a numbered SCR-CCM.04 field) — controls whether the Content Player records completion for this item (AR#3, SS-PLY.06)
• AR#1: format + size validated 2-stage — client-side pre-check (AF 2A) then server-side on receive (SS-CCM.02)
• AR#2: no separate modal alert — errors shown inline within the dialog (NFR-06)
• AR#3: Save is atomic across storage write + CourseDraftResource row + CourseDraftItem link; any failure rolls back all three (SS-CCM.07)
• AR#5: WCAG-AA — file input label association, accessible progress bar, inline error association, full keyboard navigation
• Open issues: OI-30 (format whitelist confirmed as JPG/PNG/WebP; max size still TBD — deferred), OI-31 (automatic image resize/optimization — deferred to design phase), OI-32 (EXIF metadata stripping for privacy — deferred to design phase)
