Adds the MinorPlanet capability end to end (30th shipped capability):

  • Recognition: single kernel RegexMatcher grammar (unpacked provisional incl. retrospective A8xx/A9xx and A/ lanes, case-sensitive packed 7-char, extended _ base-62, survey unpacked + packed, parenthesized + packed numbers). Syntax-only; decode coherence lives in rules.
  • Validation: 4 provenance-backed rules (MPC DesDoc / PackedDes / HowNamed) + shared mpc pack/unpack codec owned by rules/capability. Structure-only PARSER, no registry (disclosed; bare-number ambiguity e.g. phone fragments documented in integration test).
  • Contract: default designation format + offered packed wire encoding (case-exact, re-enters through packed branch; A/ lane documents fallback to designation).
  • Wiring: bootstrap _SHIPPED, lazy _LAZY/TYPE_CHECKING/all, CLI dispatch (dash-normalized), README table metadata, docs (user page, citations, glossary, migration, research + plan).
  • Tests: capability/grammar/rules/notation/integration suites, property suite, re-entry + format-preservation + surface + exports + bootstrap rows.

Includes TN-01 review cleanup (early-return A-retrospective years in mpc_pack).

Gates verified: ruff check + format, pyright strict 0 errors, import-linter KEPT, 465 passed across CLI/minor_planet/properties/re-entry/preservation/format-seam.

Summary by CodeRabbit

  • New Features
    • Added Minor Planet designation support for unpacked, packed, survey, and numbered forms, with canonical designation output and an optional packed format.
    • Added Minor Planet support to the command-line interface and shipped capability list, bringing the total to 30.
  • Documentation
    • Added a Minor Planet capability guide and updated the capability overview, API reference, migration guide, and citations.

📝 Walkthrough

Walkthrough

This change adds MinorPlanet as a built-in capability. It recognizes minor-planet designation forms, validates their structure, supports packed output, registers the capability, and adds tests and documentation.

Merge Risk: 🔵 Low · up to aada5

Packed output for rare 19xx designations with very high cycle numbers can decode to a different year. Add the year guard before merge, since it is a small fix; the rest of the capability looks sound.

Security Architecture Review

Security architecture risk: 🔵 Low · up to aada5

Packed output can silently change some accepted designations to a different century when read back. The demonstrated impact is confined to MinorPlanet identifier integrity; no new privileged operation or cross-service access was identified.

Retained concerns

  • Medium · architecture · inferred: The new packed encoder loses century information for accepted 19xx designations that enter the extended lane and have year suffixes 00–61. For example, 1900 AA620 and 2000 AA620 both encode as _0A0000, whose decoder returns 2000 AA620. This violates the public same-entity encoding contract and permits silent identifier conflation across output and subsequent ingestion. Validation of the original designation does not contain the problem because the engine publishes formatted values after identity decisions. No sensitive downstream use was established.
Security review details

Security Blast Radius

  • inferred — The demonstrated exposure is the MinorPlanet identifier-output boundary. Caller-selected packed output can conflate distinct canonical designations. The inspected conversion path performs local string and arithmetic operations, with no credential, network, or persistent-write sink established.

Security Findings and Attack Paths

  • inferred — A caller can supply structurally accepted 1900 AA620 and request packed output, producing _0A0000. Default-contract ingestion of that spelling yields 2000 AA620. This establishes an identifier-integrity failure, not a verified authorization exploit; sensitive downstream reliance was not supplied.

Trust Boundaries and Controls

  • observed — Packed input requires a nonempty spelling that successfully decodes before normalization. The engine retains pre-format identity decisions and provenance, but these controls do not verify that the emitted encoding represents that same identity.

Hardening Proposals

  • proposed — Restrict extended encoding to its supported century and verify that any emitted pack decodes to the original canonical designation. Unsupported mappings can use the existing designation fallback rather than silently substituting identity.

- Around line 207-212: Update mpc_pack’s extended underscore-packing branch to
return None for years outside the 20xx century before encoding the year code,
allowing format_value to fall back to the designation and preserving the
original year on re-entry.

mpc_pack encoded the extended _ lane with only the 2-digit year while
mpc_unpack hardcodes the 20xx century, so 19xx designations past the
7-char cycle range (e.g. 1950 AA1000 -> _oA02TE) re-entered as 2050.
Return None so format_value falls back to the designation; 19xx cycles
within 7-char range still pack exactly (century in year letter).

comment verdict reason
coderabbitai mpc_codec.py:212 extended packing drops century for non-20xx Fix now Reproduced live: mpc_pack('1950 AA1000') -> _oA02TE -> re-enters as 2050 AA1000. Real ADR-0011/re-entry break, in-scope. Fixed + replied on thread.
sourcery-ai size-limit notice No action Informational only.

Fix: extended _ branch returns None for non-20xx years (unpack hardcodes 20xx); format_value falls back to designation (same pattern as A/ lane). 19xx small cycles still pack exactly. Docstring updated. No deferred items, no follow-up issues filed.

CI: all green at last check (ci 3.11/3.12/3.13 pass, docs build pass, CodeRabbit pass). Local gates after fix: ruff check + format pass, pyright strict 0 errors, import-linter KEPT, 469 passed (minor_planet suites + properties + re-entry + preservation + cli + format seam).

Merge state: MERGEABLE but BLOCKED — needs maintainer approval; nothing further I can clear from here.
