Directive Engine
Convert nominal ↔ as-built deltas into installer-ready directive cards (move/rotate/index), with 3D visualization and verification loops.
Problem
When something is off in the field, the hardest part is not detecting it — it’s expressing the correction in a field-executable format that’s:
Inputs (Signal)
Data format: JSON with paired nominal/as-built coordinates, part IDs, and optional constraint metadata.
Calibration
The engine aligns nominal and as-built coordinate systems using anchor point pairs. Calibration quality is measured by:
RMS > 5mm, re-check anchor pairing before proceeding. High residuals propagate to all downstream directives.
Constraints / DOF
Each part has defined degrees of freedom that limit valid corrections:
Example: Panel P-0132
Panel can only be adjusted in Z-translation and X-rotation (shimming + tilt).
Action Format (Directive Card)
The engine outputs directive cards — structured correction instructions:
DIRECTIVE: P-0132
PENDING
Action: Translate +12mm Z, Rotate -0.3° about X-axis
Frame: Part-local (or site grid)
Verify: Post-adjustment deviation < 3mm
Verification Loop
After applying directives, the system runs a verification pass:
1.8mm (tolerance: 3mm)
Artifacts
Limits + Next Steps
- Single-part directives (no multi-part dependency chains yet)
- Manual anchor pairing (auto-matching in progress)
- Browser-only (no native mobile app)
Roadmap:
- Step ordering / dependencies (anchors → part → verification)
- Confidence scoring +
NEEDS_REVIEWflags for marginal cases - Tolerance heatmaps / clustering visualization
- Optional: AR overlay as a skin, not the core logic
