Activity editor workflow handoff

30-slice activity editor workflow handoff for page layout, workflow navigation, form sections, AI draft boundaries, source-material safety, readiness review, save gating, and privacy guard.

Workflow source
editor.tsWorkflow steps, anchors, and privacy boundaries are owned by the activity editor domain.
Step count
5 stepsThe workflow keeps the teacher editor to five scan-friendly sections.
Workflow order
frame -> ai-draft -> content -> source-materials -> reviewRoute navigation and form sections use one stable step order.
Create page surface
Create pageThe public create page receives the prepared workflow view from the activity editor domain.
Edit page surface
Create/edit formThe same workflow sections are reused when an owned activity is reopened for editing.
Workflow nav
Shared step navThe workflow navigation uses the same step ids, section anchors, labels, and descriptions as the form.
Form section surface
ActivityCreateFormThe activity form renders prepared sections rather than rebuilding step copy locally.
Side preview surface
Template + preview asideThe side panel keeps template entry context, input-shape help, and live preview beside the editor.
Frame section
Configurar la actividadThe frame step establishes title, template mode, and starter example context.
Primary fields
ActivityEditorPrimaryFieldsPrimary fields keep the selected template legible before scaffold, AI, or structured content edits.
Template handoff
ActivityEditorTemplateHandoffViewTemplate readiness evidence remains available as a hidden semantic handoff inside the frame step.
Scaffold panel
Template scaffoldThe scaffold panel loads reusable classroom examples into the same editor contract.
AI draft step
Crear un borrador a partir del contenidoThe AI draft step keeps optional generation inside the normal activity editor.
AI source state
ActivityEditorAiDraftPanelViewAI draft state comes from the prepared panel view, including safe source readiness and warnings.
AI source sync
Source material syncThe sync action turns attached material references into safe source notes without reading file bytes.
Content section
Editar el contenido reutilizableThe content section owns reusable classroom fields before any template renders them.
Details fields
ActivityEditorDetailsFieldsDetails fields capture title, description, subject, grade, difficulty, language, visibility, and learning goal.
Structured content fields
ActivityEditorStructuredContentFieldsStructured content fields capture vocabulary, questions, pairs, groups, source summary, and teacher notes.
Source materials section
Attach source materialsThe source-material section keeps teacher files attached for provenance and later extraction.
Material picker
Source material pickerThe source-material picker stays owner-scoped and passes only safe material references into the editor.
Review section
Revisar antes de guardarThe review step keeps readiness checks adjacent to the final save action.
Readiness panel
Template readinessThe readiness panel confirms which templates are playable before the teacher saves.
Save action footerThe sticky save footer remains the only persistence action for the activity editor.
Auth gate
Teacher sign-in requiredUnauthenticated teachers can inspect the editor but must sign in before saving.
Input contract
CreateActivityInputAll save and AI application paths continue through the shared CreateActivityInput contract.
Readiness contract
TemplateRemixPlanReadiness review uses the same template-remix diagnosis that powers scaffold and compatibility views.
AI editor boundary
Draft fills editor onlyAI drafts can fill the editor for teacher review but cannot save or publish by themselves.
Source privacy boundary
Private materials hiddenAttached materials stay private provenance and are not exposed to student payloads by the editor workflow.
Publish boundary
Save before publishPublishing remains a later assignment step after the activity is reviewed and saved.
Privacy guard
Private classroom text hiddenThe workflow handoff exposes structure, counts, section names, and boundaries without prompts, answers, teacher notes, raw input, file ids, or storage keys.

Paso 2

Crear un borrador a partir del contenido

Paste lesson notes, sync safe source materials, or generate a teacher-reviewable draft.

AI draft boundary handoff

30-slice AI draft boundary handoff for authenticated generation, safe source provenance, editor review, no-persistence behavior, draft coverage, and privacy guards.

Source panel
AI draft panelThe visible AI source panel is the teacher review surface before generation.
Generation gate
BlockedThe current source, auth state, and pending state decide whether the generate action is ready.
Auth boundary
Authenticated actionGeneration still goes through the authenticated activity draft server function before any editor fields are changed.
Server function
generateActivityDraftThe client calls one server function instead of persisting activity rows directly.
Input schema
generateActivityDraftInputSchemaDraft requests are validated by the shared generateActivityDraft input schema.
Número de elementos
5 itemsRequested item count is bounded before it reaches the draft service.
Objetivo del borrador
Actividad equilibradaThe selected draft focus is sent with the request and displayed as generation provenance.
Template
CuestionarioThe selected primary template is preserved in the draft request and result boundary.
Source sanitization
Sanitized sourceTeacher source notes are normalized and material-note payloads are sanitized before prompting.
Safe sources
0 safe sourcesOnly safe material kind and filename provenance can be included in the AI prompt.
Omitted sources
0 omitted sourcesUnsafe, duplicate, or incomplete material notes are counted but their payloads stay hidden.
File-byte guard
Bytes omittedAttached classroom file bytes are not read by this draft generation boundary.
Storage-key guard
Storage hiddenStorage keys, URLs, path segments, query tokens, and permission metadata stay out of draft requests and handoff values.
Provider
Awaiting draftProvider provenance distinguishes Workers AI output from deterministic fallback drafts.
Model
@cf/meta/llama-3.2-3b-instructModel provenance is shown without raw provider output.
Fallback path
Fallback availableMissing credentials, invalid JSON, or partial output fall back to deterministic local drafting before editor review.
JSON boundary
Schema enforcedProvider output must parse into the expected draft shape or fall back to the local generator.
Local completion
No noticePartial provider drafts may be completed locally so required classroom structures stay present.
Input contract
CreateActivityInputAI output is converted into the same CreateActivityInput contract the editor saves.
Review mode
editor-reviewDraft application mode remains editor review, never direct persistence.
Persistence
not-persistedGenerated drafts remain not persisted until the teacher saves the activity.
Teacher review
RequiredTeachers must inspect generated content, answers, explanations, and readiness before saving.
Editor application
PendingOnly reviewable draft results with the expected review state may be applied to editor fields.
Save boundary
Teacher saves laterThe draft only fills editor fields; saving remains an explicit teacher action.
Publish boundary
Publish laterAssignment links are never published by generation; teachers publish later after saving.
Coverage
PendingCoverage summarizes generated questions, pairs, groups, vocabulary, and notes without showing draft text.
Template readiness
PendingReady and locked template counts come from deterministic readiness, not AI-only claims.
Quiz choices
PendingQuiz choice readiness is summarized without exposing prompts, choices, or answers.
Generation notice
No noticeFallback or local-completion notices are summarized without raw provider errors.
Privacy guard
Private data omittedThis handoff omits source text, draft text, prompts, choices, answers, teacher notes, file ids, storage keys, file bytes, omitted note payloads, and raw provider output.

Source material picker handoff

30-slice source-material picker contract for owner scope, load state, attachment limits, attach/remove controls, upload entry, metadata summaries, AI extraction readiness, and private file guards.

Owner scope
Current teacherThe picker only works with classroom files owned by the current teacher.
Storage load gate
Sign-in requiredThe load gate keeps classroom file queries behind the signed-in teacher workspace.
Picker status
Signed outPicker status resolves from sign-in, loading, error, empty, and available states before controls render.
Selected count
0Selected count is normalized, deduplicated by source-material key, and capped before reaching the editor.
Available count
0Available count reflects the owner-scoped classroom files returned to this picker view.
Visible available limit
Bounded listThe available-file list is intentionally bounded so large source libraries do not overload the editor picker.
Attachment limit
Up to 12 filesThe attachment limit keeps ActivityContent source-material references bounded inside the editor.
Limit gate
Within limitThe limit gate disables new attachment actions once the activity reaches the source-material cap.
Attached summary
0The attached summary reports extraction-capability families without exposing teacher filenames or file ids.
Attached items
0Attached item count is derived from normalized ActivityContent source-material references.
Available items
0Available item rows remain teacher-only file choices and are never copied into student runtime payloads.
Selected state
0Selected-state count marks available rows that are already attached to the current draft.
Attach actions
0Attach actions add source-material references to the draft without reading file bytes or publishing anything.
Disabled attach actions
0Disabled attach actions are caused by already-selected materials or the activity-level attachment cap.
Remove action
Reference-only changeRemove actions detach a source-material reference from the activity draft without deleting the uploaded file.
Upload entry
Upload filesThe upload entry sends teachers to the source-material library instead of creating files inside the activity editor.
Loading state
InactiveThe loading state describes the pending owner-scoped file query before file rows render.
Error state
InactiveThe error state keeps file-loading failure visible without leaking provider errors or storage details.
Empty state
InactiveThe empty state tells teachers that no owner-scoped classroom files are available yet.
Signed-out state
ActiveThe signed-out state blocks file loading and directs teachers to sign in before attaching classroom materials.
Material-kind metadata
Kind and basenameMaterial-kind metadata drives audio, worksheet, spreadsheet, and reference-only summaries.
Content-type metadata
Normalized content typeContent-type metadata is normalized for material classification instead of being trusted as private file content.
Size metadata
Rounded sizeSize metadata is rounded into display-only summaries and does not imply file-byte reads.
Source-material reference
ActivityContent.sourceMaterialsAttached items write compact references into ActivityContent.sourceMaterials.
AI extraction readiness
0The picker summarizes attached audio, worksheet, and spreadsheet capabilities for later teacher-reviewed AI extraction.
Student payload guard
Runtime file list hiddenStudent assignment payloads receive sanitized runtime prompts and choices, not the teacher's source-material list.
File-id guard
File ids hiddenFile ids remain out of the semantic handoff even though attach/remove actions use them internally.
Filename display boundary
Teacher-only basenameTeacher-visible basenames may appear in picker rows, but the handoff itself reports only counts and boundaries.
Storage-key guard
Storage hiddenStorage keys, URLs, query tokens, and permission metadata stay server-side and out of picker semantics.
Privacy guard
Private data hiddenThe handoff hides file bytes, file ids, storage keys, permission metadata, student payload file references, and raw private filenames.
