Research: Mirror three glossary terms into the built-in pack

Phase 0 detail lives in research/code-grounding.md. Decisions:

Rationale: neither file is generated; the parity gate requires both. Alternatives considered: pack-only plus _MISSION_ADDED_SURFACES registration (rejected: the issue and the precedent mirror into the seed).

Rationale: the glossary DRG builder keeps only active senses; draft would not resolve. Alternatives considered: draft to echo candidate (rejected for that reason).

Rationale: the schema has no dedicated field; synonyms_to_avoid is the established metadata slot. Alternatives considered: banned_synonyms (rejected: inert slot under the inert-slot baseline).

Rationale: shrink-only provenance ratchet on built-in pack files.

  • Decision: edit both files by hand and append the terms at the end.
  • Decision: status active, confidence 0.9.
  • Decision: "do not use" guidance as a definition passage plus synonyms_to_avoid.
  • Decision: pack text cites ADR ids and docs/context/ entries, never issue numbers or src/ paths.
