P10 dogfooding found that a k8s manifest with 2+ documents (e.g.
Deployment + Service in one file) fails to ingest:
UNIQUE constraint failed: chunks.chunk_id
Root cause: tier2_shared::push_chunks_with_oversize's non-oversize branch
hardcoded split_key = None. K8sManifestResourceV1Chunker calls it once per
resource; with split_key None every resource from the same document gets
the same id_hash (= base_policy_hash) → identical chunk_id. p10-3's
code_text_paragraph_v1 had the same bug (fixed in df3c5b8) but it calls
build_chunk_no_symbol directly — the push_chunks_with_oversize path was
never fixed.
Fix: push_chunks_with_oversize gains a base_split_key parameter for the
non-oversize single-chunk case. k8s chunker passes Some(resource.line_start)
so each resource gets a distinct chunk_id; dockerfile / manifest pass None
(1 chunk per file — no sibling collision, chunk_id stays stable).
Regression coverage: k8s_multi_doc_emits_one_chunk_per_resource now asserts
chunk_id distinctness; new integration test
tier2_k8s_multi_resource_yaml_ingests_without_collision ingests a real
2-document YAML end-to-end.

Spec p10-2 risks section calls out "거대 ConfigMap" but no test exercised
the line-window split branch of tier2_shared::push_chunks_with_oversize.
This adds a 256-line ConfigMap fixture (generated inline) and asserts:
- ≥2 chunks emitted (split happened),
- all chunks share symbol `ConfigMap/prod/big`,
- chunk_ids all distinct (id_for_chunk's #L{k} suffix disambiguation),
- line ranges form a contiguous partition (prev.line_end + 1 == next.line_start).
Reviewer nit #1 (PR #153 code-reviewer).

Splits multi-document YAML by ^---\s*$, requires apiVersion + kind string
fields per document, emits 1 chunk per recognized k8s resource. Symbol =
<kind>/<namespace>/<name> or <kind>/<name> (cluster-scoped). Invalid YAML
returns 0 chunks (handled by p10-3 paragraph fallback). Oversize >200 lines
splits into line-windows sharing the same symbol.
tier2_shared module hosts the oversize fallback + Chunk-construction helper
mirroring code_rust_ast_v1's Chunk shape. Task E (dockerfile) and Task F
(manifest) will reuse it.
