Learning Objectives controls objective generation and is independent of teaching purpose. Quiz Blueprint and Question Generation can vary by Support Learning, Assess Understanding, or Gamify Learning. Coverage, question-history summary, and validation prompts have separate categories because they perform different tasks.
+Quiz Blueprint decides what should be generated: the fixed coverage budget, question-type allocation, objective and subpoint coverage, Bloom levels, difficulty, and rationale. Question Generation writes the actual stem, answer, distractors, feedback, or other type-specific content for one approved Blueprint allocation. They can share the same teaching-purpose strategy, but their locked task responsibilities are different.
+
+## Editable and locked instructions
+
+The **Editable course instructions** box stores course-specific teaching context and reusable preferences. **Locked CREATE instructions** shows the workflow responsibility that CREATE always applies. Runtime guardrails summarize additional constraints such as output schemas, delivery compatibility, evidence retrieval, and question-history memory. Locked instructions are read-only so a course override cannot break saved-data contracts or make an unsupported package.
+
+The panel shows the real course-level layer used by the workflow. Current objectives, evidence excerpts, Blueprint rows, history, counts, and output schemas are inserted dynamically when a request runs, so they are summarized rather than displayed as one stale prompt in settings.
+
## Course prompts versus one-time instructions
A course prompt defines repeatable behavior for future operations in that course. Instruction boxes in Learning Objectives, AI Blueprint, regeneration, and question generation apply only to the current request. Put stable terminology, audience assumptions, and course-wide constraints in a course prompt; put a one-off focus or exception in the local instruction box.
## Validate before saving
-Validation checks required placeholders, length, grounding guidance, duplication guidance, and risky instructions. A warning does not always block saving, but missing required structure can prevent the prompt from supplying data the workflow needs.
+Validation checks required placeholders, length, grounding guidance, duplication guidance, and risky instructions. It reviews the editable course layer together with the locked CREATE instructions and runtime context, so it should not report missing objectives, evidence, question schemas, or counts that CREATE injects automatically. An unchanged system default is recognized as valid without asking the AI reviewer to invent improvements.
+
+When AI review identifies a meaningful, fixable issue, the validation result includes **Apply Changes**. This replaces only the text in the editable draft; it does not save or activate the prompt. Review the revised text, run **Validate** again, and then select **Save Course Prompt** if the result matches your intent.
Do not remove placeholders simply because their raw names look technical. They are replaced with the current objectives, materials, history, or requested total when an operation runs.

Generation is a draft, not approval. Check every objective against the intended curriculum and the source material.
+## Understand the generation log
+
+The **Live generation log** explains what CREATE is doing before model text appears. It first resolves generation settings, reads the assigned material chunks, builds a source inventory, groups related sections into instructional clusters, and cleans document noise into a teaching-focused digest. The log reports safe aggregate results such as section, chunk, cluster, and topic counts; it does not display course source text or private model reasoning.
+
+When drafting starts, the same log adds a **Live model draft** section. After the draft returns, CREATE checks whether the required source sections are covered and may run a targeted repair pass before saving the objectives. A long preparation stage does not by itself mean generation is stuck, but an error event in the log identifies the stage that needs attention.
+
## Add existing or manual objectives
Paste existing objectives into the generation instructions when you want the model to preserve or refine a provided set. Use **Add Manually** when wording must be stored exactly as entered. Manual entry is also useful when a required objective is not stated explicitly in the uploaded material.
+When objectives already exist, select **Add New** to open the complete manual editor. Enter the objective text, optionally select Remember, Understand, Apply, Analyze, Evaluate, or Create, and add, edit, or remove custom subpoints before saving.

+Generated objectives already include source references and generation metadata, so they do not show a separate Enrich action. A manually added objective can be enriched from assigned materials; enrichment adds relevant metadata and references without replacing an instructor-entered Bloom level or instructor-entered subpoints.
+
+Use the **AI Enrich** action beside a manually created objective when only that LO should be enriched. Enrichment keeps the objective wording and manual Bloom/subpoints.
