New policy["answer_mode"] = "claim_lattice_pointer" (default "quote").
The runtime builds an evidence map with two-layer ids — pointer-id
(E1, E2, ...) shown to the model, sha256-derived evidence-id used by
the cache & run-DAG — and the model emits pointer-line prose
("Claim. [E12]") referencing them. Renderer interpolates literal
source spans at display time. Synthetic-elision-by-construction-
impossible: the model never types the quote string.
Pieces:
- aborist/qa/evidence.py (new): EvidenceObject + spotlight excerpt
(claim-token-centered window into the cited span, falls back to
leading window when no token matches).
- aborist/qa/parse_claims.py (new): pointer-line parser walks
lines, pulls [E\d+] / [E\d+,E\d+,...] tags, returns ParsedClaim
with PARSED / NO_EVIDENCE_POINTER status. Strict regex refuses
fuzzy alternatives so honest UNGROUNDED beats lax acceptance.
- aborist/qa/verify.py: verify_claim_lattice. Hard checks only —
parser succeeded, evidence_id resolves, source_role allowed, no
manual quotes (any " char violates), claim text non-empty.
Returns evidence_id_pairs (content-addressed, run-stable) for the
run-DAG. Soft signals (entailment, completeness, predicate
compatibility) stay sidecar.
- aborist/qa/dag.py: 9-stage CTI shape when evidence_map_root is
supplied — question / retrieval / evidence_map / prompt /
raw_answer / parsed_claim_lattice / verify / render /
final_label. Quote mode keeps the original 7-stage shape so
pre-G0 run_dag_root values stay valid.
- aborist/qa/query.py: per-chunk evidence-map build with role-
weighted budget AND query-relevance ordering. Within each source,
chunks are ranked by (distinct_query_tokens_present,
total_mentions, doc_order_asc) so the chunk most likely to
textually support the question gets the lowest pointer id. Without
this re-rank Hermes-3-8B lazy-anchored on doc-order-first chunks
regardless of relevance.
- aborist/qa/runner.py: same answer_mode branch for the single-doc
ask() path. No iterative repair in pointer mode (one-shot
benchmark discipline).
- aborist/store.py: verifier_method CHECK extended with
'claim_lattice'. New _rebuild_providence_cache_claim_lattice
migration preserves run_dag_root / run_dag_blob across the
rebuild — older rebuilds dropped them.
- aborist/cli.py: --answer-mode {quote,claim_lattice_pointer} on
query and ask.
- Makefile: ANSWER_MODE knob; defaults to claim_lattice_pointer for
`make query` so the testing harness exercises the new path.
Library DEFAULT_POLICY / DEFAULT_QUERY_POLICY stay "quote" so
Python callers and unit tests aren't surprised.
Prompt: one-shot worked example (Apple founders) plus strict
no-quotes / no-JSON / no-markdown / plain-prose-only rules. Without
the worked example Hermes-3-8B drops the bracket protocol on roughly
half of runs; with it, JP dinosaurs benchmark went 0/13 -> 10/11 ->
16/17 verified across the iterations that hardened the pipeline.
Tests: +48 covering parser, two-layer ids, verifier failure modes
(UNKNOWN_EVIDENCE_ID / SOURCE_ROLE_BLOCKED / MANUAL_QUOTE_VIOLATION
/ NO_EVIDENCE_POINTER / SCHEMA_INVALID), spotlight rendering with
buried-term fixture, per-chunk evidence map, query-relevance
ordering, schema migration round-trip, 9-stage DAG shape divergence.
Total 438 passed, all 7 production shards report 0 chain breaks.
Known limitation: chunk boundaries can cut wikitext mid-template, so
mwparserfromhell-backed to_base() leaves orphan </ref> tags and
leading list markers in the visible spotlight excerpts. Verifier and
CTI architecture are unaffected; the leak is cosmetic. Proper fixes
are template-aware chunking (chunker bump invalidates prior records)
or an orphan-marker post-strip in aborist/wikitext.py — both out of
G0 scope.
