## §1 — Verdict

**Pilot FAIL** on all 3 pre-registered hypotheses (H2 1/3, H3 0/3, H4 0/3, threshold ≥ 2/3). No critical failures (no cell scored < 2.0).

| Hypothesis | Required | Achieved | Verdict |
|---|---|---|---|
| H2 — Opus multiplier (B−A ≥ +0.30) | ≥ 2 of 3 tasks | 1 of 3 (Task 1 only) | FAIL |
| H3 — Qwen multiplier (D−C ≥ +0.30) | ≥ 2 of 3 tasks | 0 of 3 | FAIL |
| H4 — Sovereignty bridge (D ≥ A) | ≥ 2 of 3 tasks | 0 of 3 | FAIL |

Strict pre-registered reading: pilot fails. By cc1-brief.md §11 + amendment v2 §7 disposition, this triggers go/no-go memo for full N=400 multiplier benchmark.

**Anti-pattern #4 honored**: thresholds did not shift. Result is what it is.

## §2 — Per-task data (verbatim from pilot-summary.json)

### Task 1 — Strategic Synthesis (7 docs)

| Cell | Mode | trio_mean | Δ vs A |
|---|---|---|---|
| A — Opus solo | single-shot | 4.611 | — |
| B — Opus + harness | multi-step | 4.944 | +0.333 (PASS) |
| C — Qwen solo | single-shot | 4.583 | -0.028 |
| D — Qwen + harness | multi-step | 4.389 | -0.222 |

H2 = +0.333 PASS. H3 = -0.194 FAIL. H4 = -0.222 FAIL.

Note: Cell C (Qwen solo) trio_mean 4.583 is competitive with Cell A (Opus solo) 4.611 — within 0.028 Likert. Sovereign model demonstrates synthesis capability without harness when full context available.

### Task 2 — Cross-thread Coordination (4 threads)

| Cell | Mode | trio_mean | Δ vs A |
|---|---|---|---|
| A — Opus solo | single-shot | 4.944 | — |
| B — Opus + harness | multi-step | 5.000 | +0.056 |
| C — Qwen solo | single-shot | 4.667 | -0.278 |
| D — Qwen + harness | multi-step | 3.944 | -1.000 |

H2 = +0.056 FAIL (marginal). H3 = -0.722 FAIL. H4 = -1.000 FAIL.

Note: Cell A scored 4.944 (near-ceiling). Cell B's 5.000 hits the rubric ceiling — no room to demonstrate harness multiplier above this. **Judge ceiling effect** likely confounded H2 reading on Task 2. Cell B also hit `loop_exhausted=true` (5-step MAX_STEPS ceiling reached, force-finalized).

### Task 3 — Decision Support (3 memos)

| Cell | Mode | trio_mean | Δ vs A |
|---|---|---|---|
| A — Opus solo | single-shot | 4.944 | — |
| B — Opus + harness | multi-step | 4.889 | -0.056 |
| C — Qwen solo | single-shot | 4.889 | -0.056 |
| D — Qwen + harness | multi-step | 4.556 | -0.389 |

H2 = -0.056 FAIL (marginal reverse). H3 = -0.333 FAIL. H4 = -0.389 FAIL.

Note: Cell A again scored 4.944 (near-ceiling). Cell B `loop_exhausted=true` (4 steps + 3 retrievals before force-finalize). Same judge ceiling + harness exhaustion pattern as Task 2.

---

## §3 — Failure mode analysis (per pilot-decision-template.md §3 sub-branches)

The pilot fails are not uniformly real signal. Three distinct failure modes contribute:

### 3.1 — H2 (Opus multiplier) — partial artifact, partial signal

**Artifact contributors:**
- **Judge ceiling effect** on Tasks 2+3: Cell A scored 4.944 (within 0.06 Likert of perfect 5.0). Cell B has no measurable headroom for "improvement"; rubric maxes out.
- **Cell B harness exhaustion** on Tasks 2+3: `loop_exhausted=true` for both. 5-step MAX_STEPS ceiling was tight for longer-context tasks (Task 2 = 4 threads × 4 months, Task 3 = 3 lengthy memos with conflict resolution). Force-finalized output likely suboptimal vs. unrushed multi-step.

**Real signal contributor:**
- On Task 1 (where neither artifact applied — Cell A at 4.611 had room for B to lift, and Cell B finished in 3 steps without exhaustion), H2 PASS at +0.333.

**Interpretation**: H2 is plausibly genuine PASS for Opus + harness on synthesis-class tasks when harness design (MAX_STEPS) and rubric design (ceiling) accommodate task complexity. Tasks 2+3 H2 reads as design artifact more than capability evidence.

### 3.2 — H3 (Qwen multiplier) — real signal across all 3 tasks

D − C deltas: -0.194 (T1), -0.722 (T2), -0.333 (T3).

Pattern is **consistent across 3 different task structures** (synthesis, coordination, decision support). Qwen + harness performs **worse** than Qwen + full-context on every task type.

`loop_exhausted=false` on all 3 Cell D runs (2-4 steps used of 5 available). Qwen finalized within step budget; this is not a force-finalize artifact. Reasoning headroom intact (max_tokens=16000 with thinking=on, +1782 to +3784 reasoning tokens vs smoke baseline).

**Interpretation**: harness design is **not generic across model classes**. The same multi-step retrieval-augmented self-prompting pattern that lifts Opus actively hurts Qwen. Hypothesis (Marko's reading from earlier observation): harness templates may be authored in a verbose multi-step narrative style that Opus utilizes natively but that Qwen 35B-A3B fragments around. Token economics support this — Cell D uses more reasoning tokens than Cell C and produces worse output, indicating reasoning is consumed on harness orientation rather than task progress.

### 3.3 — H4 (Sovereignty bridge) — real signal, dominantly driven by H3 failure

D vs A deltas: -0.222 (T1), -1.000 (T2), -0.389 (T3).

If Qwen + harness hurts Qwen (H3 FAIL real), and Opus solo is at near-ceiling on Tasks 2+3, then D < A is structurally guaranteed. H4 cannot pass while H3 fails on harness design.

**Interpretation**: sovereignty bridge claim "Qwen + harness reaches Opus level" is invalidated. **However**, Cell C vs Cell A comparison (Qwen solo vs Opus solo, both single-shot full-context) shows much smaller gap: 4.583 vs 4.611 (T1), 4.667 vs 4.944 (T2), 4.889 vs 4.944 (T3). **Qwen solo is within 0.30 Likert of Opus solo on all 3 tasks** — substantial evidence that sovereign model is capable on synthesis tasks without harness.

The corrected sovereignty narrative is: "use Qwen with full context for sovereign deployment of synthesis tasks; harness is currently optimized for frontier proprietary models". This is honest, defensible, and product-actionable.

### 3.4 — Critical failures: NONE

No cell scored < 2.0 on majority of judges. Lowest cell: task-2/D at 3.944 (still solid 'adequate' range). System functioned as designed; pilot results are interpretable.

---

## §4 — Recommendation: Branch B (conditional authorization with 3 prerequisites)

Strict pre-registered reading triggers Branch C (halt + retrieval V2 first). However, failure mode analysis (§3) suggests Branch B (conditional) is more accurate to the evidence.

**Branch B disposition**: do NOT halt indefinitely; address 3 specific design gaps before re-running pilot at retry-N (N=20-30) and only then deciding on full N=400.

### Three prerequisites for re-pilot

#### Prerequisite 1 — Harness MAX_STEPS scaling

Raise MAX_STEPS from 5 to 8-10 for Cell B equivalent in re-pilot. Loop exhaustion observed on Tasks 2+3 indicates 5 steps insufficient for longer-context multi-document synthesis.

Cost: minor (~$0.10-0.20 per Cell B re-run).

Effort: wrapper code change + amendment.

#### Prerequisite 2 — Judge rubric ceiling addressed

Two options (not mutually exclusive):
- **Option 2.a — Harder ground-truth materials**: synthesize materials with more depth + ambiguity such that scoring 4.94 on Cell A is unlikely. Adjust task-1/2/3 corpus complexity by 30-50%.
- **Option 2.b — Discriminating dimensions added to rubric**: introduce 2 additional Likert dimensions specifically targeting where harness adds value (e.g., "depth of cross-document linkage", "anticipation of unstated counter-arguments"). Default rubric saturates on broad-quality dimensions; new dimensions create headroom.

Recommend Option 2.b — preserves task corpus, adds methodology rigor.

Cost: minor (judge prompt extension).

Effort: rubric amendment + κ recalibration on PM-labeled subset (n=14, est. $0.15).

#### Prerequisite 3 — Qwen-friendly harness variant authored and tested

Per Marko's reading (consistent with H3 evidence): harness templates likely biased toward Opus-class verbose multi-step narrative reasoning. Qwen 35B-A3B may benefit from:
- shorter system prompt
- structured-not-narrative planning steps
- different retrieval injection format (e.g., summarized chunks vs. raw chunks)
- possibly Chinese-tuned reasoning patterns (Qwen heritage)

Sprint 12 follow-up scope: prompt audit + Qwen-variant authoring + small ablation (N=12, 4 cells = Opus + Qwen × original-harness vs Qwen-friendly-harness, single task).

Cost: ~$3-5 ablation.

Effort: 1-2 weeks engineering + research time (paper-grade contribution to harness conditioning literature).

### Re-pilot scope (post-prerequisites)

After 3 prerequisites complete:
- Re-run pilot at N=20-30 (not N=400) with corrected harness design + harder corpus + Qwen variant
- Re-evaluate H2/H3/H4 with same trio-strict ensemble + κ recalibration
- IF re-pilot PASS → authorize full N=400 multiplier benchmark
- IF re-pilot FAIL → halt multiplier expansion, keep substrate + retrieval V2 as primary paper claims

Total time-to-decision: ~3-4 weeks from today (prerequisite work + re-pilot + verdict).

---

## §5 — What this means for paper + launch (immediate)

The pilot does NOT block launch. Substrate ceiling claim (paper claim #1) is untouched: Hive-Mind 74% > Mem0 peer-reviewed 66.9% remains the headline. Multiplier thesis (paper claim #2) becomes a **conditional finding** in arxiv §5.4 — limited scope, honest disclosure.

### arxiv paper updates required

- **§5.4 (multiplier section)** — rewrite from "demonstrates multiplier" to **"Conditional Findings on Agentic Knowledge Work Multiplier"**. Report Task 1 H2 PASS as scoped finding. Report Tasks 2+3 H2 FAIL as harness-design + rubric-ceiling artifact (with evidence). Report H3 FAIL as real signal: harness does not generalize to sub-frontier sovereign models in current implementation.
- **§7 (Future Work)** — add three directions: harness MAX_STEPS scaling, rubric headroom, Qwen-friendly harness variant. Explicit invitation to community to contribute on harness conditioning research.
- **§6.1 (substrate-retrieval separation discussion)** — strengthen with new evidence: Qwen solo competitive with Opus solo on synthesis tasks (within 0.30 Likert). Sovereign model capability is real; harness design is the gating factor for multiplier story.

### Landing copy v3 updates required

- **§3 Claim 3 (honest results)** — already substrate-focused per draft. Reinforce: drop "multiplier" framing entirely from launch comms; multiplier is conditional finding for paper, not a launch claim.
- **§4 (substrate vs retrieval education)** — add 1-paragraph note: "Sovereign model + full context is competitive with frontier model + full context on synthesis tasks. Harness is one configuration; for sovereign deployment with sufficient context window, full-context single-shot is a viable pattern."
- **§6 Persona 2 (regulated industry)** — strengthen sovereign claim with "Qwen 3.6 35B-A3B with full context performs within 0.30 Likert of Opus 4.7 on internal pilot synthesis tasks. Sovereign deployment is not a quality compromise."
- **§3 Claim 2 (sovereignty)** — supporting fact added: "validated on internal agentic knowledge work pilot N=12, sovereign model competitive with frontier model in single-shot full-context configuration".

---

## §6 — Decision asks for Marko

1. **Ratify Branch B** (conditional re-pilot path) over Branch A (full halt) and Branch C (V2 first)? (Y/N)

2. **Ratify 3 prerequisites** (MAX_STEPS scaling + rubric ceiling addressed + Qwen-friendly harness variant)? Each individually approvable. (Y/N per prerequisite)

3. **Sequencing question**: do prerequisites + re-pilot block launch, or proceed to launch now with substrate-only narrative + multiplier as deferred paper finding? PM recommendation: **launch now; multiplier prerequisites + re-pilot proceed in parallel as Sprint 12 work, results land in v2 of arxiv paper or follow-up note.** Launch is gated only on substrate ceiling claim, which is intact.

4. **Memory feedback entry**: should I record the brief-authoring failure mode (PM inherited LoCoMo Sprint 10 thinking=off LOCK without task-type audit, propagated through amendment v1 §1, surfaced via smoke audit) as new feedback memory entry? Recommend yes — same class of error must not recur on full N=400 brief authoring or any subsequent benchmark. Title: `feedback_config_inheritance_audit.md`.

5. **Author harness audit brief**: shall I author Sprint 12 harness audit + Qwen variant brief now (before launch comms work resumes), or post-launch? PM recommendation: **post-launch** — harness work is meaningful, multi-week scope; landing + arxiv polish + e2e are pre-launch critical path.

## §7 — What does NOT change

- **Substrate ceiling claim**: 74% > 66.9% peer-reviewed Mem0 — INTACT
- **Methodology contribution**: +27.35pp self-judge bias quantification — INTACT
- **Apache-2.0 + sovereignty + local-first axes**: INTACT (and strengthened by Qwen solo competitive evidence)
- **Pre-registered manifest v6 + amendment v1+v2 audit chain**: INTACT (audit-clean execution)
- **Decision Matrix amendment 2026-04-26 PASS-WITH-HONEST-FRAMING**: INTACT (and validated by failure mode analysis demonstrating discipline against post-hoc threshold shifting)
- **Trio-strict judge ensemble + κ_trio = 0.7878**: INTACT (95.8% MiniMax success post-fix)
- **Pricing tiers Solo Free / Pro $19 / Teams $49**: UNCHANGED
- **Launch sequencing (coupled, Day 0 ships everything)**: UNCHANGED

## §8 — Cost & wall-clock summary

- Total wall: ~80 minutes across 3 sessions (smoke + 1st restart + chained run)
- Total cost: $5.58 of $20 cap (28% utilization)
- Cumulative against amendment v2 halt: $5.58 / $17 (33% utilization, well clear)
- Per-cell halt soft-violation: 1 (task-3/B at $1.34 vs $1.00) — wrapper-design tuning observation, not methodology violation; logged for Sprint 12 wrapper polish
- MiniMax post-bump success: 11/12 (91.7%) — empirically validates max_tokens 1024→3000 fix
