From c28e107dc7a12b536f8c13598749e9c68cfabae7 Mon Sep 17 00:00:00 2001 From: Shay Date: Mon, 18 May 2026 06:36:10 -0700 Subject: [PATCH] feat(adr-0048): pack-grounded surface for cold-start DEFINITION/RECALL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the surface-grounding gap isolated by ADR-0047's characterisation. Adds the ratified cognition pack as a second grounding source alongside the session vault. == chat/pack_grounding.py (new) == Loads en_core_cognition_v1's lexicon once (cached; immutable pack) and exposes: pack_grounded_surface(lemma) -> str | None Returns a deterministic, fully pack-sourced surface: "{lemma} — pack-grounded ({pack_id}): {d1}; {d2}; {d3}. No session evidence yet." Every visible atom is the lemma or a verbatim semantic_domains string from the pack. No rewording, no synthesis, no LLM. == chat/runtime.py == _stub_response gains optional pack_grounded_surface= parameter. _maybe_pack_grounded_surface routes to the pack only when all four hold: gate_source=="empty_vault", output_language=="en", intent.tag in {DEFINITION, RECALL}, and intent.subject is a pack lemma. Safety/ethics refusal still takes priority above this branch. ChatResponse and TurnEvent gain grounding_source ∈ {vault,pack,none}.
