refs #216 Architect drift review over 68317ec..6e22c98 (two items, both fixed here; code and ledger verified drift-clean): - The authoring guide's 'Register and run' transcript still showed the pre-regime world (2 cells, regime-less family ids) directly under the worked example this cycle made two-regime / 4-cell. The transcript now shows the -r1 family-id suffix, per-cell regime fields (ordinal 0 serialize-skipped, the established byte-stability pattern), the four cells, per-regime generalization entries, and a prose paragraph tying the 4 cells to the validate count (regimes compared, never pooled). - The fresh glossary entry declared 'Avoid: stop regime' while this very cycle ships 'stop regimes' in its hint strings and guide prose — an Avoid line the codebase itself violates records intent, not reality. 'stop regime' is dropped from Avoid ('risk section' stays: it wrongly suggests a section rather than an axis list). What holds (architect): content-id parity untouched (probe is read-only, canonical bytes unchanged); the validate cell product mirrors the exec cross-product exactly; all six spec acceptance criteria shipped. Regression: cargo test --workspace 62 result groups / 0 failures; clippy -D warnings clean; cargo doc 0 warnings (all at 6e22c98; this commit is docs-only).
