# SilverSight Glossary

A living dictionary of terms used across the SilverSight core, libraries, documentation, and receipts.

**Rule:** Every entry must name the authoritative source file or module. A glossary entry without a source module is a draft; it must be promoted to a bound definition before it is used in a receipt or gate.

**Deep Wiki Compatible:** Each entry includes File:Line references, tags for categorization, and cross-references to related terms.

## Standard Terminology Crosswalk

SilverSight invents names only when necessary. When a concept already exists under a standard name, the glossary binds the SilverSight name to the standard name and explains the delta.

| SilverSight Term | Standard Terminology | Delta / Note | File:Line | Tags | See Also |
|------------------|----------------------|--------------|-----------|------|----------|
| **Sidon set** | B₂ sequence, Erdős–Sidon set | Standard combinatorial object; SilverSight uses it for deterministic strand addressing. | formal/CoreFormalism/SidonSets.lean:L1 | #mathematical #core | [Sidon label](#sidon-label) |
| **Sidon label** | Sidon-set element, B₂ address | Chosen from the canonical powers-of-2 set for 8-strand braids. | formal/CoreFormalism/InteractionGraphSidon.lean:L1 | #mathematical #core | [Sidon set](#sidon-set) |
| **Q16_16** | Fixed-point arithmetic, Q15.16 / s16.16 | Signed 32-bit fixed point with 16 integer and 16 fractional bits. | Core/SilverSight/FixedPoint.lean:L1 | #core #implementation | [Q0_16](#q0_16) |
| **BraidStorm** | Braid group representation, Artin braid | 8-strand braid action used as a compression/determinism substrate. | formal/CoreFormalism/BraidEigensolid.lean:L1 | #mathematical #core | [eigensolid](#eigensolid) |
| **eigensolid** | Fixed point, attractor | Fixed point of the crossStep operator; not a physical solid. | formal/CoreFormalism/BraidEigensolid.lean:L42 | #mathematical #core | [crossStep](#crossstep) |
| **crossStep** | Braid generator / crossing operator | One deterministic update step in the braid dynamics. | formal/CoreFormalism/BraidCross.lean:L1 | #mathematical #core | [eigensolid](#eigensolid) |
| **AVM** | Abstract/virtual machine, stack machine | SilverSight-specific instruction set and transition relation. | Core/SilverSightCore.lean:L1 | #core #implementation | [TIC](#tic) |
| **TIC** | Logical clock, event counter | Monotone counter derived from AVM transitions. | Core/SilverSightCore.lean:L1 | #core #implementation | [AVM](#avm) |

## How to Add or Update an Entry

1. Add a row to the appropriate table
2. Make the File:Line column point at the exact file and line number
3. Add relevant Tags for categorization
4. Add See Also links to related terms using #anchor format
5. Run python3 -m py_compile on any touched Python and lake build on any touched Lean
