PHASE6B_ROOT_CURRICULUM_EXPANSION.md — the phase summary: what was
authored per course, the is_required extension, the capstone unlock
fix, verified scenario coverage before/after (44 -> 88 of 98, 89.8%,
by direct query not estimate), and honest known limitations/Phase 6C
recommendations.
ROOT_CAPSTONE_READINESS.md — the readiness module and the server-side
unlock fix in full detail, including why the module's completion and
the real assessment's unlock gate are deliberately independent systems.
Updated ROOT_CURRICULUM_INVENTORY.md (Phase 6B coverage numbers),
ROOT_PROGRAM_ARCHITECTURE.md (ROOT 08/09 PARTIAL, new module lists per
course), COURSE_CONTENT_MODEL.md (is_required completion rule, a new
content-versioning section per this phase's own requirement),
COURSE_AUTHORING_STANDARD.md (classifying near-duplicate/advanced
scenarios), ENGINEERING_SOP.md (new Phase 6B section),
REMOTE_AND_SELF_PACED_ARCHITECTURE.md (cross-reference), and
platform/README.md (e2e-phase6b.js, the Phase 6B rehearsal, isolation-
per-suite regression guidance).

New tables (courses, course_modules, module_activities,
activity_completions) layered over the existing scenario/assessment/
achievement systems — a lab activity references an existing scenario_id,
an assessment/capstone activity references an existing
assessment_definition_id, neither duplicated. Long-form lesson prose
lives in git-tracked Markdown (content/root/), split into shared vs.
instructor-only sections by a '## Instructor Notes' heading convention
(content.js) rather than a second file or a CMS.
course-progress.js derives completion from EXISTING sources only:
auto_scenario reads the progress table, auto_assessment reads
achievements by assessment_definition_id, manual_marker is the one
genuinely new piece of state (for lesson-only activities with nothing
else to derive completion from). Prerequisite locking treats a
zero-content (PLANNED) prerequisite as vacuously satisfied, so an
honestly-unbuilt course never permanently locks everything after it.
Found by testing: computing a level's prerequisite lock and stripping
its working totals in the same map iteration made the result depend on
iteration order. Fixed with two explicit passes.
