 ## OVERVIEW
-Paxman is a Python 3.11+ canonicalization library with a small CLI: takes ambiguous human input, returns what authoritative specs say it means, with full provenance. Deterministic, provenance-first. 28 capabilities (BIC, ChemicalElement, Coordinates, Country, CreditCard, Currency, Date, DOI, Domain, Email, GTIN, IBAN, IP, ISBN, ISIN, ISNI, ISSN, Language, LEI, MacAddress, Money, ORCID, Phone, SI Unit, Timezone, URL, UtcOffset, UUID) — recognition via the Recognition Kernel (ADR-0009) with legacy pipeline stages retained for unmigrated grammars. Toolchain: uv + hatchling, ruff, strict pyright, import-linter, pytest at 95% coverage.

@@ -61,6 +61,7 @@ Capability-defined intermediate representation that Grammars must produce:
 - **UtcOffset:** `UtcOffsetNotation(compact)` — `compact` is the grammar-normalized extended `+HH:MM` form (`Z` → `+00:00`); rules own range validation (`-12:00..+14:00`, `-00:00` refused)
 - **UUID:** `UUIDNotation(compact, hyphenated, urn, version)` — `compact` is the 32-hex lowercase form, `hyphenated` the `8-4-4-4-12` canonical, `urn` the `urn:uuid:` carrier, `version` the version nibble (informative, never gates)
 - **UNSPSC:** `UNSPSCNotation(digits, level, function, native_length)` — `digits` is the 8-digit zero-padded stem (6-digit class alias padded `+"00"` by the grammar; 10-digit input keeps its 8-digit stem), `level` is `"segment"` / `"family"` / `"class"` / `"commodity"` from trailing-`00` pairs (no authority lookup), `function` the 2-digit BFI suffix or `""`, `native_length` the spelled digit length (6/8/10, retained as the `native` format facet); grammar never validates membership — rules own it
+- **MinorPlanet:** `MinorPlanetNotation(designation, form, packed)` — `designation` is the syntax-normalized spelled form (unpacked lanes upper/single-space, packed lanes byte-for-byte), `form` the lane id (`provisional` | `packed` | `extended` | `survey` | `survey_packed` | `number` | `packed_number`), `packed` the spelled packed form for packed lanes else `""`; grammar never decodes — rules own coherence via `mpc_codec`
 - **Phone / URL:** capability-defined shapes for address / number / URI components
