Analysis methodology

After you submit a floor plan and metadata, the server runs a multi-step model pipeline and stores progress in the database; the result page polls for updates. Paid vs unpaid paths differ:

1. Validate input, create an analysis row, and atomically claim free quota if applicable.
2. Unpaid preview: run preview_scan only — area, orientation, room count, up to three short issue labels (not full extraction).
3. Paid or free first full run: vision model extracts structure (rooms, doors/windows, orientation JSON).
4. Type-specific steps: ming tang / sha, lucky positions, annotated plan, multi-floor synthesis, surrounding analysis (residential) or shop-specific analysis.
5. Paid enrichment: energy-school steps for flow geometry, structured diagnosis, optional infographic / stills / walkthrough (env flags apply).
6. Deliver an on-page printable report; annotated images are stored on the analysis record (e.g. data URLs).

Prompts and model steps are visible in admin; this page matches that configuration — we do not claim capabilities the code does not run:

• ◆San Yuan Xuan Kong, Ba Zhai, Form School — applied via step prompts and optional classical RAG chunks.
• ◆Vision for plan structure; text models return JSON contracts for the UI.
• ◆RAG: admins upload PDFs that are chunked and embedded; upload does not guarantee every analysis queries them.
• ◆Energy flow viewer: prefers pipeline coordinates; otherwise a deterministic fallback from door direction and markers.

We can: structured reference reports from your plan and form data. We cannot: replace on-site inspection; guarantee perfect AI recognition; predict personal fortune; or provide medical, legal, or investment advice.

Non-standard, low-quality, or north-less plans may mis-parse; schools of feng shui may disagree; external sha often needs physical presence.
