+# Run 6 — `if007_scratch_merged_108`: if-007's full 108-task evaluation
+
+The evolved interface `evol/qwen_syn30v15_128k_scratch/if-007` (from Run 2),
+run with Prime Agent on `simular-qwen-3p8-27b-evolving-agents` over all 108
+tasks: 93 held-out (`heldout_93/`) plus the 15 val tasks the evolution used as
+fitness (`val_15/`, taken from the evolution eval cache). **One directory per
+task, the episode the row counts**, plus `scores.csv` (score, source run,
+harness, replaced score and reason per task), `MANIFEST.json`, and the
+interface code (`shadow_interface_if-007/`).
+

+Run 3 (bare) 47.526.
+
+### Which episode each task counts
+
+- Held-out: the latest completed run of `full_minus_val_93` → `remaining_41`
+  → `ce_rerun_4` → `499_rerun_1`. The last two re-measure 042 067 094 106,
+  whose episodes were cut by infrastructure (a `Connection error` while the
+  LiteLLM proxy was resized, then a `499 Client Closed Request` on 042).
+- Five tasks count a re-run instead of the original episode:
+  - **043 063 080 086** — the original ended on a reply that hit the 32k
+    output cap with no tool call (`stopReason=length`), which Prime's loop
+    treats as a finished episode, so the task was scored mid-thought (0.0625,
+    0, 0, 0). Re-run with `SHADOW_EVOL_LENGTH_CONTINUATIONS=3`: the harness
+    resumes the same session after such a reply. Only 043 actually resumed
+    (twice); 063, 080 and 086 did not truncate on the re-run.
+    New scores 0.6875, 0.7, 0.657, 0.1.
+  - **066** — the original ended on `422 No valid tool call after 6
+    attempts` (0); plain re-run, 1.0.
+
+### Caveats
+
+- **Harness difference.** The four length-continuation re-runs used a harness
+  the seed and bare rows did not. Compare with seed on the strict row.
+- **n = 1 per task.** Re-running one variant moves a task by ~0.19 on average
+  in this namespace; single-task differences are not findings.
+- The length truncation is task-driven, not specific to if-007: 043
+  truncates under seed and bare too.
+- Recordings omitted. Redaction: 412 `NAME=value` credentials replaced with
+  `<REDACTED>`; the wider pre-upload scan found no credential shape.
