fix(workplans): adopt ADR-007 derived identifiers

Records absent from central carried random pre-ADR-007 identifiers minted by
the retired local hub, which C-06 refused as stale references. Deriving from
the canonical record id takes no identity from anything.

+# Module: `problem_stress.flat_any_open`
+
+| | |
+|---|---|
+| **aspect** | `problem_stress` |
+| **role** | End of round: if **any** Problem unclaimed → **each** seat +1 Stress |
+| **status** | measured → reject as sole pressure (H1-A); keep for A/B |
+| **legacy** | H1-A half of `h1-problem-stress` |
+| **measurement** | [RPT-0004](../../../../reports/260808-clay-borg-h1-measured.md) |
+
+**Compose with:** any `end_condition`, `problem_deal`, `attack_relief`.  
+**Conflicts with:** other `problem_stress.*` modules (one per aspect).
+
+Known result: flat tax → solve-rate collapse at 3p+ under greedy (when used alone or with H1-B).
