# Verification snapshot — September 13, 2026

Original Stage 2 implementation: TypeScript/production build passed; 61 unit tests and 7 isolated browser tests passed. All 36 handlers were exercised by automated tests. Tests include revisions, validation, undo/redo, persistence, resources, PNG/PDF generation and backup restoration. Automated ZIP/PDF outputs were downloaded and parsed for dimensions and page counts.

A real Codex in-app browser discovered native tools and successfully invoked context reading, six-slide creation, layout validation, PNG/PDF export, export status, slide selection and reopening after reload. The final six-slide “AI evaluations: from demo to evidence” deck returned no mechanical layout issues and both exports completed at revision 0. This is an observed session result, not a browser/model compatibility guarantee.

Full native acceptance of every tool, exhaustive aesthetic review, real quota/eviction behavior and a controlled speed/token comparison are not complete. The original planned coding model does not independently establish the exact runtime model used. No performance claim is made. Stage 3 in BUILD-PROMPTS.md is a testing procedure viewers can execute, not a completed benchmark.

The public kit includes code/schema evidence, not browser profile data or private call-history recordings. Localhost download URLs from Amit's session are not public downloads and are intentionally not included as viewer assets.

Public-kit verification: a separate copy passed `pnpm install --frozen-lockfile`, all 61 unit tests, and `pnpm build`. Existing harmless bundler annotation/chunk-size warnings remain. Browser suites were not rerun for documentation-only packaging; source files match the tested implementation.
