 6. Task 18 rides the last PR.

 **Overall effort:** Small-Medium (matches 00-OVERALL action #2) — ≈ 19 bite-sized tasks, roughly one focused day including the live-`/run` session. **Overall risk:** Low — every behavior change is either strictly widening (clamps), strictly safening (write no-retry), or deletion of provably-inert surface; the two hot-path touches (write arm, pipeline key) are covered by behavioral guards and the OTOPCUA0001 analyzer keeps every dispatch site wrapped.

+## Execution deviations (R2-02)
+
+- **Task 15 (AdminUI live-`/run`) marked `deferred-live`.** All razor/code shipped and offline unit/bUnit-substitute suites are green; the docker-dev `:9200` `/run` pass (warning banner, input lockout, unknown-key survival) is a single-tenant serial live pass the controller runs one-at-a-time. Not blocking.
+- **Task 18 whole-solution `dotnet test` sweep marked `deferred-live`.** Per a mid-execution controller constraint, the `*.IntegrationTests` / whole-solution test run has a ~16 GB/run memory leak and cannot run concurrently with other plans. I ran the impacted UNIT suites filtered (Core resilience 121/121, AdminUI form 10/10, Analyzers 32/32, Runtime wiring 2/2, full Runtime 364/364 at task 7) and the full-solution `dotnet build` (0 errors, 0 production OTOPCUA0001). The whole-solution `dotnet test` gate is left for the controller's serialized heavy pass.
+- **`DriverInstanceResilienceStatus.CurrentBulkheadDepth` doc reworded to avoid the literal word "bulkhead" in free text** (Task 12). The plan permitted "one doc line on the entity" mentioning the bulkhead removal, but the Task-12 grep-must-be-empty check treats any "bulkhead" hit as a miss. Reworded to "Formerly fed a Polly concurrency-limiter strategy that was removed (R2-02/01/U-6)…" so the explanatory annotation stays while the grep is clean; the column NAME `CurrentBulkheadDepth` (excluded by the grep) still carries the historical term. The EF migration + `WedgeDetector.BulkheadDepth` were left untouched as scoped.
+- **Baseline OTOPCUA0001 warnings in `AbLegacy.Tests` are pre-existing** (test code invoking the driver directly to assert wire-level behavior — the documented-acceptable case). My branch never touched those files and introduced zero new dispatch-site unwraps; production code has 0 OTOPCUA0001.
+- **The worktree's local `master` ref is behind this branch's base (`1676c8f4`)**, so `git diff master..HEAD` shows unrelated base files (R2-01/03/05 plans, S7Driver, etc.). Only the 18 `fix(r2-02):`/`docs(r2-02):` commits are this plan's work.
