The financial model inside the packs is dated September and is left as it is;
what changed is the product evidence. The banner says exactly that instead of
rewriting history, and points at the A4 sheet built from today's measurements.

Two editions of the seed pack, one financial model, and a one-page sheet for a
first meeting.
| Path | What it is |
| --- | --- |
| `aegis_investor_pack_en/` | English edition: the pack, six charts, the engine, model outputs, the A4 one-pager |
| `paquete_inversor_aegis_es/` | Spanish edition of the same, with peso amounts in parentheses |
| `one_page/` | Source of the A4 sheet: copy with tokens, the builder, the two PDFs and their checksums |
The packs share one financial engine and one `model_outputs.json`; the one-page
sheet reads the repository's measured facts and the model, never a retyped number.
## Check
```bash
cd aegis_investor_pack_en && sha256sum -c SHA256SUMS
cd ../paquete_inversor_aegis_es && sha256sum -c SHA256SUMS
cd ../one_page && python3 build.py --check
```
## Rebuild the one-pager
```bash
cd one_page && python3 build.py
```
It renders both PDFs with headless Chromium and then verifies them with poppler:
one page, A4 (595 x 842 pt), the expected text present and no unembedded font.
