Captures the lean-build redesign work: goal, session journal, Athanor
usage research from dirigent and spacecraft, and the implementation
and review reports.
Research tree on using the orbit code-graph CLI for review in Rust
projects: the Python/Django field guide recorded as phase 0, orbit 0.133
capabilities on spacecraft and dirigent, fit with Spire's review stage,
and tested review recipes (changed definitions, blast radius, blindness
preflight). Includes the orbit-skill goal and the Igor session journal.
Igor now has a Development Cycle section with six stages, review decision
tree, Athanor queuing rules, and separation principle. Athanor, implementation,
research, and research-tree skills all reference their cycle stage. Fixed
remaining Athanor metaphor inversions in the plugin design spec.
