Root cause: recalled_words was built from result.tokens (versor walk
neighbours) rather than the pack-resolved proposition slots. The walk
produces nearest-neighbour traversal artifacts; the proposition already
carries the correct subject/predicate/object from realize(). This made
ground_graph() fill <pending> obj slots with stop-word-adjacent tokens
instead of the actual answer content.
Fix — two changes, one new helper:
generate/intent_bridge.py
• build_recalled_words_from_plan(plan, proposition, walk_tokens)
Constructs the grounding tuple in priority order:
1. plan.object (ArticulationPlan — pack-resolved, already a word)
2. proposition.object_ (Proposition — versor-decoded object slot)
3. plan.predicate (descriptive predicate word, richer than walk)
4. plan.subject (subject as last-resort semantic anchor)
5. walk_tokens (result.tokens alpha-filtered — supplemental backfill)
Strips <pending>/<prior>/empty/non-alpha before deduplicating.
Returns a deduplicated tuple in that priority order.
• articulate_with_intent() gains an optional `proposition` param
(typed as object to avoid import coupling at the call site).
When provided, build_recalled_words_from_plan() is called to
replace the raw recalled_words before ground_graph() runs.
When omitted, behaviour is byte-identical to Phase 1 (backward
compatible: all existing callers and tests pass unchanged).
chat/runtime.py
• The single articulate_with_intent() call site now passes
proposition=proposition so the bridge receives the full
pack-resolved proposition for grounding. walk_tokens (the old
recalled_words) are passed through as supplemental backfill.
• No change to ChatResponse, TurnEvent, GenerationResult, or any
ADR-gated schema.
