Poneglyph is institutional memory for development consulting projects. Six specialized agents on Claude Opus 4.7 read scattered field evidence — scanned Hindi forms, meeting transcripts, CSV exports — catch silent commitment drift across stakeholder meetings, and draft pre-meeting briefings with every claim independently audited.

Three Opus 4.7 capabilities exercised at production quality. Scout extracts evidence from handwritten Hindi attendance forms with pixel-coordinate bounding boxes — no OCR pipeline, no fine-tuning. Archivist uses on-demand tool reads to navigate project memory the way a human consultant uses a binder, detecting silent walk-backs the project team did not acknowledge. Auditor takes the Drafter's claims and re-reads source images independently with vision, refusing to confirm anything it cannot ground — same model, two different roles, with vision, refusing to lie.

12/12 evidence extractions, 3/3 drift detection across variance runs, 89% aggregate eval pass rate across 28 test cases. Seven documented failure modes in the repo.

$200B+ flows annually from World Bank, GIZ, and UN agencies through this kind of consulting work. Built in five days. Live demo: https://poneglyph-chi.vercel.app
