R280 verification transcript

R280_catalog | catalog_rows | expected_22
             |     22       | t

R280_targets | distinct_target_functions | all_resolvable
             |     20                    | t

all_resolvable=true — both new target_functions resolve in pg_proc.public. The [[feedback-dot-catalog-target-functions-fn-names-only]] rule (fn names only, no table names) is upheld.

SSOT alignment

Python dot_commands.DOT_COMMANDS (22 governed + 8 external) ↔ SQL runtime/280 INSERT (22 rows) ↔ Live dot_iu_command_catalog (22 rows) ↔ pg_proc.public (all target fns resolvable). All four layers locked.

Operator runbook coverage (OPERATOR_RUNBOOK.md)

1. Cheat sheet — 12 product-factory DOT → fn mapping
2. End-to-end recipe — open composer gate → compose template → mark → generate instance → record lineage → close gate
3. Validation + inspection — list active templates, list lineage, validate / render
4. Rollback recipes — soft un-register, erase lineage, migration rollback with REFUSED guard
5. Healthcheck integration — refresh iu_three_axis_envelope after compose
6. Event emission rehearsal — dry-run pattern
7. SSOT pointers — every relevant file
