🐺 Fenrir Burn Night Analysis — Issue #11: Add Portfolio Optimization Module

What This Issue Is Asking For

Comprehensive portfolio optimization:

  1. Mean-variance (Markowitz) optimization
  2. Risk parity allocation
  3. Black-Litterman model
  4. Constraint handling (long-only, sector limits, turnover)
  5. Efficient frontier visualization
  6. Backend: scipy.optimize
  7. Module: turboquant/portfolio/optimizer.py

Current Status Assessment

Partially implemented, far from spec. Current optimizer.py:

# Simple inverse-variance weighting — NOT true Markowitz
inv_var = 1.0 / np.diag(covariance_matrix)
weights = inv_var / inv_var.sum()
weights = np.clip(weights, min_w, max_w)

Gap Analysis

Requirement Status
Mean-variance (Markowitz) Placeholder — inverse-variance, no scipy.optimize
Risk parity Missing
Black-Litterman Missing
Constraints Basic min/max clip only. No sector/turnover/cardinality
Efficient frontier Missing
scipy.optimize Not used
Module path Wrong — turboquant/optimizer.py not turboquant/portfolio/optimizer.py

Technical Design

True Markowitz

from scipy.optimize import minimize

def objective(w):
    return -w @ expected_returns + risk_aversion * (w @ cov @ w)

result = minimize(objective, x0, method='SLSQP', bounds=bounds, constraints=constraints)

Risk Parity

Minimize squared difference between each asset's risk contribution and target budget. Uses scipy.optimize.minimize with SLSQP.

Black-Litterman (Master Formula)

tau_sigma = tau * cov_matrix
M = inv(inv(tau_sigma) + P.T @ inv(omega) @ P)
posterior = M @ (inv(tau_sigma) @ pi + P.T @ inv(omega) @ Q)

Constraint System

Dataclass-based constraints converted to scipy constraint dicts. Support: long-only, sector limits, turnover, cardinality.

Efficient Frontier

Sweep target returns from min to max, minimize variance at each target. Plot with matplotlib (optional dep).

Proposed Structure

turboquant/portfolio/
├── optimizer.py          # Markowitz core
├── risk_parity.py        # Risk parity
├── black_litterman.py    # BL model
├── constraints.py        # Constraint builder
└── frontier.py           # Efficient frontier + plotting

Blockers

Blocker Severity
scipy not in deps Medium
matplotlib not in deps Medium (optional)
Existing 4 tests need migration Medium

Recommended Next Steps

  1. Keep open — this IS the library's core purpose
  2. Add scipy to pyproject.toml
  3. Implement: Markowitz → Constraints → Risk Parity → Black-Litterman → Frontier
  4. Keep backward-compatible API, add new methods
  5. Priority: CRITICAL — most important issue in the repo

Verdict: KEEP OPEN — Most important issue. Current optimizer is a placeholder. This is what makes TurboQuant a real library. Priority: CRITICAL.

The wolf knows: a pack's strength is in its core. This is the core.

🐺 Fenrir — Deep Technical Analysis (Burn Night)

Issue Assessment: Full Test Matrix — 10 Prompts + Quality + Performance

Classification: Phase 2 — comprehensive validation gate (GO/NO-GO decision)
Labels: benchmark, owner:cid, owner:john, phase-2
Dependencies: #10 (Ollama deploy) + #16 (test prompts) — BOTH BLOCKING
Existing comment: Timmy posted partial Phase 1 performance results

This Is the Kill Gate

This issue is the go/no-go decision point for TurboQuant in production. Everything before this is preparation; everything after depends on this passing. Let me break down every test in the matrix.

QUALITY TESTS — Deep Dive

1. Perplexity (PPL) — WikiText-2

Parameter Value
Tool llama-perplexity
Dataset WikiText-2 (standard)
Pass criteria PPL delta ≤ 0.5
Kill criteria (from epic) PPL regression > 1.0

Phase 1 results (from PHASE1-REPORT.md):

Config PPL Delta
FP16 KV (baseline) 6.92 —
turbo4 7.14 +0.22

Status: PASS ✅ (delta 0.22 < 0.5 threshold)

This test is essentially complete from Phase 1. However, Phase 1 was run with a specific model on the fork's llama-perplexity. Phase 2 should re-run on the production model (qwen3.5:27b) to confirm.

Caveat: WikiText-2 PPL uses relatively short contexts. It won't catch long-context degradation — that's what tests 2 and 4 are for.

2. Needle-in-Haystack

Parameter Value
Tool Custom prompts
Context lengths 8K, 16K, 32K, 64K, 128K
Pass criteria 100% retrieval at all lengths

Status: NOT STARTED ❌

This is the most critical quality test for TurboQuant's value proposition. If the whole point is 128K context, we MUST prove needle retrieval works at 128K.

Implementation approach:

def needle_test(context_length, model_endpoint):
    # Generate haystack of {context_length} tokens
    haystack = generate_filler_text(context_length - 200)
    needle = "The secret passphrase is GOLDEN_EAGLE_42."
    
    # Insert needle at random position
    insert_pos = random.randint(len(haystack)//4, 3*len(haystack)//4)
    text = haystack[:insert_pos] + needle + haystack[insert_pos:]
    
    prompt = text + "\n\nWhat is the secret passphrase?"
    response = query_model(model_endpoint, prompt)
    
    return "GOLDEN_EAGLE_42" in response

Must test at ALL specified lengths. The 128K test is the hardest — it pushes the KV cache to maximum compression load.

Risk: At 128K context with turbo4 compression, we're looking at ~3.5 bits/channel × 128K tokens × 27B model's head count. If any layer's quantization is lossy enough to shift attention away from the needle, retrieval fails.

3. 10 Practical Prompts — Human Review

Parameter Value
Tool Side-by-side comparison
Pass criteria No degradation on ≥ 9/10 prompts
Reviewer John

Status: PARTIALLY READY ⚠️

Prompts exist in repo (see #16 analysis) but don't match spec complexity. This test requires:

  1. Run all 10 prompts on TurboQuant config → save outputs
  2. Run all 10 prompts on FP16 baseline → save outputs
  3. Present side-by-side to John (blinded — don't tell him which is which)
  4. John rates each pair: TQ better / same / worse

Tooling needed: A comparison viewer. Could be as simple as:

# Generate comparison HTML
python3 generate_comparison.py --tq results_turbo4.json --baseline results_fp16.json --output comparison.html

4. Attention Accuracy — Cosine Similarity

Parameter Value
Tool Custom attention weight extraction
Pass criteria Cosine similarity ≥ 0.995

Status: NOT STARTED ❌ — HARDEST TEST TO IMPLEMENT

This requires extracting raw attention weights from both configurations and comparing them. This is non-trivial because:

  1. llama.cpp doesn't expose attention weights by default — need to modify the inference code or use profiling hooks
  2. Must compare layer-by-layer — aggregate cosine sim could hide per-layer issues
  3. Memory intensive — storing attention weights for comparison at 128K context is enormous

Implementation path:

  • The fork's Metal shaders have profiling modes mentioned in PHASE1-REPORT.md
  • Could use --attention-dump flag if the fork supports it
  • Alternative: compute attention score distributions (not raw weights) and compare those

Recommendation: This may need to be simplified to "attention output cosine similarity" rather than raw attention weights. The outputs of each attention layer are more practical to capture.

PERFORMANCE TESTS — Deep Dive

5. Tokens per Second (tok/s)

Parameter Value
Tool llama-bench
Pass criteria ≥ 90% of baseline

Phase 1 results (from PHASE1-REPORT.md):

Config Prompt tok/s Gen tok/s
FP16 552 26.3
turbo4 546 23.4
  • Prompt eval: 546/552 = 98.9% of baseline ✅
  • Generation: 23.4/26.3 = 89.0% of baseline ⚠️ MARGINAL

Generation tok/s is at 89%, just under the 90% threshold. This needs attention. The 11% generation overhead comes from dequantization in the attention hot loop.

Mitigation path: The kernel_attention_turbo4 fused kernel in ggml-metal-turbo.metal is currently a stub ("Conceptual" comment). Fusing dequantization into the attention kernel could recover the missing 1-2%.

6. Time to First Token (TTFT)

Parameter Value
Tool Timed prompt eval
Pass criteria ≤ 110% of baseline

Phase 1 data: Prompt eval speed is 98.9% of baseline, implying TTFT is ~101% of baseline. PASS ✅

7. Peak Memory

Parameter Value
Tool footprint / vmmap
Pass criteria Under 27GB at target context

Phase 1 results:

Config Memory at 128K
FP16 27.6GB (OOM risk on 32GB)
turbo4 7.3GB KV (73% savings)

Total system memory with turbo4: Model (~14GB for Q4_K_M 27B) + 7.3GB KV + overhead ≈ ~23GB. Well under 27GB. PASS ✅

Note: Hardware is actually M3 Max 36GB (not M4 Max 32GB per spec), giving even more headroom.

8. Context Ceiling

Parameter Value
Tool Binary search max before OOM
Pass criteria 64K minimum

Phase 1 result: 128K achieved without OOM with turbo4. PASS ✅ (exceeds 64K minimum by 2x)

Consolidated Status Matrix

Test Status Result Blocker
PPL (WikiText-2) ✅ Phase 1 done PASS (delta 0.22) Re-run on production model
Needle-in-Haystack ❌ Not started Unknown Needs #10 + implementation
10 Practical Prompts ⚠️ Prompts exist Unknown Needs #16 completion + John
Attention Accuracy ❌ Not started Unknown Hardest — needs custom tooling
tok/s ✅ Phase 1 done ⚠️ MARGINAL (89%) Fused kernel optimization
TTFT ✅ Phase 1 done PASS (~101%) —
Peak Memory ✅ Phase 1 done PASS (23GB) —
Context Ceiling ✅ Phase 1 done PASS (128K) —

Scorecard: 4/8 complete, 1 marginal, 3 not started

John Review

John needs to review the 10-prompt comparison. This requires:

  1. Both configs running and producing outputs
  2. A clean comparison document (HTML or side-by-side markdown)
  3. Blinded review (A/B, not "TurboQuant vs Baseline")

Critical Path to GO/NO-GO

#16 (prompts) ─────┐
                    ├──→ #11 (this issue) ──→ GO/NO-GO
#10 (Ollama/server) ┘

Remaining work:
1. Fix test prompts to match spec (Issue #16)
2. Deploy llama-server with both configs (bypass Ollama if needed)
3. Implement needle-in-haystack test runner
4. Run full matrix
5. Generate comparison docs for John
6. Address tok/s marginal result (fused kernel)
7. John sign-off

Recommendations

  1. Don't wait for Ollama — use llama-server directly for the test matrix
  2. Prioritize needle-in-haystack — this is the highest-risk unknown
  3. Simplify attention accuracy test — compare attention layer outputs, not raw weights
  4. Address the tok/s marginal — the fused attention kernel is the fix
  5. Prepare John's review package — blinded, side-by-side, clean formatting
  6. Keep this issue OPEN — it's the critical gate

The wolf counts the bones. Half the matrix is proven, half awaits the hunt. The marginal tok/s is a thorn — the fused kernel must pull it above 90%. 🐺
