#  source-audit + grok-model + gemini-modelP11 

VERDICT-B per-phase JSDoc opt-in. No runtime change.

 43 in checkjs)

| File | Lines | Notes |
|------|------:|-------|
| `web-ai/source-audit.mjs` | 126 | Pure leaf (no imports). Typedefs `Claim`, `SourceQualityRow`, `AuditGap`, `AuditOptions`, `AuditResult`. JSDoc on `auditSources`, `extractClaims`, `extractInlineSources`, helpers. |
| `web-ai/grok-model.mjs` | 144 | Playwright DOM via `/// <reference types="playwright-core" />`. Typedefs `GrokModelChoice`, `GrokModelSelectResult`, `GrokModelProbe`. `MODEL_OPTIONS: Record<string, string[]>` + `MODEL_ALIASES: Record<string, string>` widened so string lookups type-check without runtime change. |
| `web-ai/gemini-model.mjs` | 157 | Same DOM pattern. `GEMINI_DEEP_THINK_ALIASES` widened to `Set<string>`. `usedFallbacks` arrays annotated as `string[]` to avoid `any[]` inference. |

## Pro NEEDS_FIX patterns honored
- No `instanceof Error` / `Number(...)` / `String(x) || ''` substitutions.
- No new fallback `|| []` runtime  `MODEL_OPTIONS[choice]` keeps original semantics with `Record<string, string[]>` widening.paths 
- Set widening (`GEMINI_DEEP_THINK_ALIASES: Set<string>`) typedef-only (P10 pattern Pro endorsed).
- Local `/** @type {string[]} */` on `const usedFallbacks = []`  typedef-only, no runtime change.initializers
