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.

+# SCN_02 re-tuned for mechanical distinctness
+
+**Date:** 2026-08-09  
+**Source:** GROUND-RPT-0006 / ADHOC-2026-08-08-T02

+clay-borg measured SCN_01 and SCN_02 as identical on suit and value at
+every priority (only titles differed). That was not intentional.
+
+## Change (SCN_02 only; titles kept)
+
+| priority | was | now | title (unchanged) |
+|---------:|-----|-----|-------------------|
+| 0 Surface | Repair | Repair | Shared Task Left Undone |
+| 1 | Clarify | **Change** | Different Standards |
+| 2 | Boundary | **Clarify** | Invisible Workload |
+| 3 | Repair | **Boundary** | Resentment Never Raised |
+| 4 | Change | **Repair** | No Ownership Routine |
+
+Point values **unchanged** (2/2/2/3/3). Thresholds unchanged.
+
+## 2p suit multiset (Surface + H1–2)
+
+| board | suits |
+|-------|--------|
+| SCN_01 | Repair, Clarify, Boundary |
+| SCN_02 | Repair, **Change**, Clarify |
+| SCN_03 | Boundary, Clarify, Repair |
+| SCN_04 | Repair, Clarify, Repair (harder) |
+
+SCN_02 is no longer a twin of SCN_01. Panels may treat four scenarios as
+four mechanical boards again (within suit/value space).
+
+Fiction note: “Different Standards” as **Change** reads as revising the
+shared standard; “Resentment” as **Boundary** as needing a limit — light
+theme stretch, acceptable for r0 playtest.
