## Why The post-#160 production trace showed a complete, bounded six-claim research pass with a valid summary. Anthropic respected the array bounds but did not enforce JSON Schema `maxLength`; Mastra post-validation rejected one 1,020-character claim against the 800-character model-facing limit. ## What changed - Remove provider-unreliable string-length constraints from model-facing claim, summary, and report fields. - Keep the working max-items limits for claims and source fan-out. - Keep explicit prompt concision, synthesis token allowance, and strict Exa/Firecrawl provenance validation unchanged. No database, migration, dependency, environment, or deployment-topology changes. ## Verification - `pnpm lint` - `pnpm typecheck` - `pnpm turbo build --force` - `pnpm deadcode` - `pnpm architecture:check` - `pnpm turbo skills:build` Production QA will repeat the complete PDF lifecycle after deployment.

Why
The production trace after PR #159 proved that Anthropic native structured output was active, but query passes generated 11-23 exhaustive claims and exhausted the response budget before emitting required fields. Responses were valid JSON prefixes cut off mid-claim or before
summary.What changed
No database, migration, dependency, environment, or deployment-topology changes.
