# MWT v0.2 Symbol Migration Map

This file records canonical v0.2 symbols without rewriting historical v0.1 sources.

| Concern | v0.1 variants | v0.2 canonical |
|---|---|---|
| World primitive | `W`, `\mathbf W` | `\mathbf W` |
| Runtime root | various state tuples | `\mathfrak R_t^{MWT}` |
| WorldRef | implicit | `w_t` / `WorldRef` |
| Context | `\Gamma` | `\Gamma` |
| Governance | `\Theta` variants | `\Theta` |
| Identity | `\mathfrak I` | `\mathfrak I` |
| Query family | `\mathcal Q` | `\mathcal Q` |
| One query | `q`, `\mathfrak Q` | `\mathfrak Q` |
| Legality rules | `\Lambda` | `\Lambda` |
| Scheduler policy | `\Sigma` | `\Sigma` |
| Resolution | `\lambda` | `\lambda` |
| Merge | `\mu` | `\mu` |
| Projection | `\Pi` | `\Pi` |
| Generic certificate | many `C_*` | `\mathfrak C` envelope + typed `C^{kind}` |
| Generic event | local records | `\mathfrak E` |
| World state | `\mathfrak S_t^{MWT}` | `\mathfrak S_t` inside runtime |
| Refinement state | `R`, `\mathcal R` variants | `\mathcal F_t^{ref}` |
| Coupling state | `C`, `GCC` | `\mathcal C_t^{cpl}` / `MWT-GCC` |
| Resource state | `B`, resource records | `\mathcal B_t^{res}`; `B_t` only budget |
| Memory state | `\mathfrak M_t^W` | `\mathfrak M_t` inside runtime |

## Acronym rule

Use namespace prefixes in runtime-visible identifiers:
- `MWT-GLC` = Global Legality Calculus
- `MWT-GCC` = Global Coupling Calculus

Historical internal acronyms are preserved only in source documents.

## Migration principle

Historical v0.1 documents are immutable sources. v0.2 adapters translate their records to canonical runtime fields. Do not silently rewrite old artifacts or hashes.
