generate-matrix

The Matriz de Alcance y Secuencia is the backbone of curricular traceability. Without it, content generation operates blind — authors cannot guarantee coverage, reviewers cannot verify alignment, and orphaned destrezas slip through to production. Build the matrix first; everything downstream depends on it.

Purpose

Generate a curriculum alignment matrix that maps every MinEduc destreza to editorial units, indicadores de logro, and taxonomy levels. The matrix serves as the single source of truth for the entire editorial pipeline — unit generation, teacher guides, rubrics, and digital resources all read from it.

Procedure

1. Read the MinEduc curriculum destrezas for the target asignatura and grado from references/priming-rag/rag-curriculo-ecuatoriano.md and references/ontology/destreza-reference-schema.md, because the official DZ format and asignatura codes define valid identifiers.
2. Extract every destreza and its associated indicadores de logro. Tag each with its DZ code (DZ-<ASIG>-<ANO>-<ID>), because downstream traceability requires unique identifiers from the start.
3. Map each destreza to a taxonomy level (Bloom + Marzano) using references/taxonomy-mapping.md, because taxonomy alignment drives the cognitive progression within and across units.
4. Group destrezas into unit sequences following complexity progression (lower-order destrezas earlier, higher-order later), because Sweller's cognitive load theory requires scaffolded introduction of concepts.
5. Assign inserciones curriculares transversales (ODS, INS-SE, INS-SI, etc.) to units ensuring at least 1 per unit, because MinEduc requires cross-cutting themes in every unit.
6. Generate the JSON matrix following the schema in the Output Format section.
7. Run coverage verification: count destrezas in matrix vs. destrezas in source curriculum. The delta should be zero — every destreza appears at least once.
8. Tag every entry with an evidence tag ([METODOLOGIA], [INFERENCIA], [SUPUESTO]), because the quality gate G1 requires traceable claims.

Inputs

Outputs

Acceptance Criteria

• 100% destreza coverage — zero orphaned destrezas (delta = 0 between source and matrix)
• Every entry has a valid DZ-<ASIG>-<ANO>-<ID> code
• Every destreza maps to at least one indicador de logro
• Taxonomy levels assigned to every destreza (both Bloom and Marzano)
• At least 1 insercion curricular transversal per unit
• JSON validates against the schema (no null required fields, valid enum values)
• Evidence tags present on 100% of entries; if >30% are [SUPUESTO], include warning banner

Error Handling

• Missing asignatura or grado: Prompt the user — these are required to identify the correct destreza set. Do not guess.
• Destrezas source unavailable: Fall back to rag-curriculo-ecuatoriano.md for known asignaturas. If the asignatura is not in scope (outside EGB Media 5-7), report the limitation and stop.
• Coverage < 100%: Do not mark as complete. List orphaned destrezas explicitly and suggest which units could absorb them.
• >30% entries tagged [SUPUESTO]: Add banner "ALTO CONTENIDO INFERIDO — Requiere validacion con fuentes primarias del MinEduc" at the top of the output.

Anti-Patterns

• Inventing destrezas: Never create destrezas not present in the MinEduc source, because phantom destrezas create false coverage and misalign the entire downstream pipeline.
• Leaving coverage gaps "for later": A partial matrix propagates gaps into units, guides, and rubrics. If a destreza cannot be mapped, flag it explicitly rather than omitting it silently.
• Flat sequencing: Dumping all destrezas into units without cognitive progression defeats the scaffolding purpose. Lower-order skills (Recordar, Comprender) should precede higher-order ones (Analizar, Crear) within and across units.
• Skipping evidence tags: Untagged entries cannot pass Gate G1. Tag everything, even obvious mappings.
