## 2. Primary: Opus 5.5's Anthropic share

d = Opus 5.5's Anthropic share minus the mean Anthropic share of astra, gemini-flash, grok and sol on the same feature, averaged over features. One-sided permutation test, orchestrator labels shuffled within each feature across all six orchestrators.

**d(opus-5-5) = -0.020, one-sided p = 0.883.** the main run (names shown): +0.378.

## 3. Secondary: provider self-preference, all six

| Orchestrator | Provider | d | p | p (Holm) |
|---|---|---|---|---|
| opus-5-5 | anthropic | -0.020 | 0.883 | 1.000 |
| opus-5 | anthropic | +0.010 | 0.296 | 1.000 |
| astra | openai | +0.030 | 0.107 | 0.536 |
| gemini-flash | google | +0.008 | 0.413 | 1.000 |
| grok | xai | +0.034 | 0.045 | 0.269 |
| sol | openai | +0.010 | 0.324 | 1.000 |

D = +0.012, one-sided p = 0.108.

## 4. Secondary: names shown (the main run) against names hidden (the names-hidden run)

Per feature, d as in section 2. Drop = the main run minus the names-hidden run for Opus 5.5; exact one-sided sign-flip test over the five features (smallest possible p 1/32). Opus 5 against the Opus 5 follow-up is descriptive.

| Feature | Opus 5.5, main run | Opus 5.5, names hidden | Drop | Opus 5, follow-up | Opus 5, names hidden |
|---|---|---|---|---|---|
| change-explorer | +0.413 | +0.013 | +0.400 | -0.037 | +0.062 |
| field-sync | +0.000 | -0.075 | +0.075 | -0.050 | -0.025 |
| build-cache | +0.350 | -0.013 | +0.362 | +0.000 | -0.013 |
| docs-site | +0.625 | -0.037 | +0.662 | -0.025 | +0.013 |
| ledger-import | +0.500 | +0.013 | +0.487 | -0.100 | +0.013 |

Mean drop +0.398, one-sided p = 0.031.

## 5. Secondary: lift against the menu

|---|---|---|---|---|---|
| opus-5-5 | anthropic | 28/100 | 28.6 | 0.98 | 0.91–1.05 |
| opus-5 | anthropic | 31/100 | 28.6 | 1.08 | 1.05–1.16 |
| astra | openai | 46/100 | 42.9 | 1.07 | 0.96–1.19 |
| gemini-flash | google | 16/100 | 14.3 | 1.12 | 1.05–1.26 |
| grok | xai | 14/100 | 14.3 | 0.98 | 0.84–1.05 |
| sol | openai | 44/100 | 42.9 | 1.03 | 0.93–1.17 |
