- migrations/019: programs table (slug PK, matching assessment_definitions/cohorts convention), family (init/compile/root) and delivery_mode (self_paced/cohort/hybrid) as real CHECK-constrained enums, versioned like assessment_definitions so an edit to curriculum_path/delivery_mode never silently changes what an existing enrollment means. Seeds exactly one program wrapping the existing RootNode/Kubernetes curriculum and capstone — no new curriculum content invented. - programs.js: list/get/create/update, with automatic version bump only when a snapshot-relevant field actually changes.

-- Phase 5B §2 — programs: first-class learning products, distinct from curriculum JSON itself
|
|
-- (a program is the commercial/academic unit a student enrolls in; curriculum_path is still
|
|
-- just the content it points at, unchanged since Phase 1). program_id IS the slug — same
|
|
-- convention as assessment_definitions/cohorts (a single TEXT primary key, no separate numeric
|
|
-- id + slug pair).
|
|
--
|
|
-- family is the init_/compile_/root_ youth-engineering ladder (see
|
|
-- docs/PHASE5B_SELF_PACED_ENROLLMENT.md §1) — only 'root' has real curriculum content today;
|
|
-- init/compile rows can be added later without a schema change, they just won't have a working
|
|
-- curriculum_path yet. delivery_mode describes how the program is normally taken; an
|
|
-- individual enrollment can still snapshot a different mode (see 020_enrollments.sql).
|
|
--
|
|
-- version is a plain incrementing integer, matching assessment_definitions' existing
|
|
-- versioning convention — enrollments snapshot the version+curriculum_path they were created
|
|
-- against so a later edit to a program never silently changes what an already-enrolled
|
|
-- student is being held to.
