The implementation skill now states the lean loop: attack the plan
against the code before building, build phases in blocks with a cheap
gate between them, test and review once per phase, one fix pass, stop.
Harness mechanics, model observations and the run-log template move to
references with dated, sourced claims.
The Athanor becomes a build furnace pinned to claude-opus-5-5: one phase
per turn, no planning, no plan attack, no self-review. It no longer
preloads superpowers; those skills stay available as tools.
