trigram tokenizer 가 snippet 단위 + 단어 경계 + BM25 raw score 분포를
모두 바꿔서 unicode61 assumption 기반의 3 test 가 regression.
- wire_search_response::search_json_truncates_with_max_tokens +
search_plain_emits_truncated_hint_to_stderr: 단일 doc + 작은
max_tokens 로는 snippet 이 짧아서 budget loop 가 trip 안 함.
다중 doc fixture (5 doc) + budget 30 token 으로 hit-pop 경로
통해 truncated=true 보장.
- fetch_integration::fetch_chunk_with_context_returns_neighbors:
fixture body 의 2-char tokens (A1/A3 등) 가 trigram 비호환으로
0-hit. apples/banana/cherry/durian/elder 5-char unique words
로 갱신, query 도 cherry 로 deterministic pin.
- eval/runner::runner_per_query_snapshot_matches_fixture: trigram
token stream 으로 BM25 raw score 변동. UPDATE_SNAPSHOTS=1 로
regenerate.

- wire schema: relax effective_end.minimum 1 → 0 + expand
description to cover line-clamp + out-of-range sentinel
(panic-fix R1 emits Some(0) when line_start=1 and range is
beyond doc end — schema must accept it)
- tests: tighten first-chunk-target boundary test to assert ≤ 2
total neighbors (3-chunk doc, N=2). Strict "first chunk →
context_before empty" not assertable until chunks.ordinal
column lands (R1 #9 architectural caveat)
- store: trim contradiction in list_chunk_ids_for_doc warning
comment — drop "good enough for sequentially chunked
markdown" phrase that conflicts with "hash sort dominates"
paragraph above

Line-based slice over fmt_canonical_to_markdown output.
PDF / audio source_type → span_not_supported StructuredError.
Out-of-range line_end clamps to total; effective_end reflects
post-budget trim. invalid_input on zero / inverted bounds.

Walks CanonicalDocument blocks, serializes to markdown, applies
chars/4 budget when opts.max_tokens is set. doc_not_found
preserved through StructuredError.

Chunk mode + +-N context. doc / span modes return placeholder
errors (filled by subsequent tasks). fmt_canonical_to_markdown
helper introduced now since doc mode (Task 4) consumes it.
Errors are typed StructuredError so classify preserves
chunk_not_found / doc_not_found through the wire layer.
Adds SqliteStore::list_chunk_ids_for_doc so the facade can derive
+-N neighbors without leaking direct rusqlite usage into kebab-app.
