+## EXP-0038 — Target Resolution V1 Diagnostic
+
+Status: Experimental; linkage boundary successful, normalization incomplete
+
+Date: 2026-08-20
+
+Forensics on failed Target Resolution V0 found a definite prompt defect: its
+illustrative value `"observation ID or null"` placed both alternatives inside
+a JSON string. V0 also sent only `format: "json"`, which enforced JSON syntax
+but not field types. This isolated diagnostic changed only the linkage/output
+boundary. It contains no rejection derivation or normative semantics.
+
+Ollama 0.32.6 accepted a true JSON Schema object in `format`. TR1-V1 removed
+target selection from the model output entirely and deterministically linked
+the self-contained candidate to itself. TR2-V1 through TR4-V1 used a closed
+allowed-ID list, an enum of those IDs plus JSON null, typed positive and null
+examples, recursive strict validation, and one fixed paired prompt. Linkage and
+normalization were persisted separately.
+
+| Case | Strategy / ID source | Target | Normalized target | Verdict |
+| --- | --- | --- | --- | --- |
+| TR1-V1 | self-contained / deterministic | `obs_1` | `Mit Dr. Schlummer arbeiten wir nicht weiter.` retained negation instead of a positive action meaning | FAIL |
+| TR2-V1 | paired / LLM | `obs_1` | `externe Lösung weiterverfolgen` | PASS |
+| TR3-V1 | paired / LLM | `obs_1` | `reale Anlage zur Diskussion` lost `Druckversuch` purpose and the `nutzen` action | FAIL |
+| TR4-V1 | paired / LLM | `obs_1` | `Versuch in der realen Anlage durchführen`; Technikum excluded | PASS |
+
+Result: two PASS, zero PARTIAL, two FAIL. All four responses passed their true
+JSON Schemas. Every resulting target was `obs_1`; wrong-target and
+unresolved-target counts were zero. The string `"null"` recurrence count was
+zero, and there were zero structural validation failures. TR1 preserved the
+collaboration, person, and continuation wording but failed positive-action
+normalization by retaining negation. TR3 had one material scope loss. TR4
+preserved real-plant scope and isolated the Technikum alternative. No
+normative leakage occurred.
+
+Configuration: exactly four `qwen3.5:9B` calls, temperature 0,
+`think=false`, `num_ctx=16384`, `num_predict=1024`, no retries, voting, or
+prompt tuning. Aggregate runner time was 4.557 seconds.
+
+Conclusion: the V0 string-null failure was primarily a linkage/output-boundary
+failure rather than evidence that observation-ID linkage is semantically
+impossible. True typed schemas, closed ID lists, and deterministic self-linkage
+eliminated every structural and target-ID failure. The experiment still fails
+its complete acceptance criterion because target normalization is not reliably
+positive or scope-preserving. These results justify separating linkage from
+normalization, but not deriving rejection or integrating a new pipeline.
+
+Artifacts are preserved under
