README: install, configure (.env + workspaces/), the workflow, run inside Pi, the
three-level test commands, layout, references.
docs/workflow-editing.md: how to edit workflow.yaml (add/reorder/merge/skip phases,
advance kinds, prerequisite predicates, decision_min_phase derivation, artifacts_out
+ teardown) -- referencing spec §5.3. Emphasizes no mirrored constants (the F2 point).
docs/testing.md: the honest L0/L1/L2 split in plain language -- what each covers and
does NOT. States the headline plainly: the skill->LLM->gate loop has NO automated
regression coverage (L2 only, pre-release). Documents the fake-Pi follow-up as the
gap-closer. Security note on keys (.env gitignored, never logged, rotate leaked keys).
