Pre-PR review fixes for the new architecture-spine skill:
- Adopt the shared canonical memlog (#2462); drop the vendored copy and the
status-flag lifecycle in favor of `event` entries
- Wire epic-altitude inheritance: parent-spine load+bind, Inherited Invariants
template section, epic-scoped run folder, parent-contradiction lens; state
that per-story detail is deferred to bmad-create-story
- Add the Update intent; honor a forwarded-activation handoff from the
deprecated bmad-create-architecture shim
- Rename modes to Coaching path / Fast path (suite-consistent with prd/brief)
and sequence the offer as an activation step
- Fix the brownfield project-context.md default path ({output_folder} no-op)
- lint_spine: line-exact frontmatter, fence-blanking (AD-in-fence + accurate
line numbers), map-form key_deps, AD-0 fix; soften template-token severity;
add 8 tests
- Carve the Reviewer Gate to references/ to stay under the SKILL.md token budget
- Template: entities-only ERD, scale-down guidance, softened seed framing;
gitignore .memlog.md
