dot-iu-cutter v0.5 — Cut-plan Dry-run & Writer Decision · Cut-plan Artifact & Digest Evidence

doc 2 of 6 · 2026-05-19 · evidence captured from the ephemeral /tmp scratch (now shredded). Artifacts are byte-reproducible by re-running the §3/doc-1 deterministic command (no DB).

3. iu_mapping_preview — derived facts (60 rows)

iu_count: 60
level_distribution: NGUYEN_TAC=15 · KIEN_TRUC_SECTION=3 · DIEU=42   (== accepted MARK identity)
effective_status_distribution: enacted=60   (enacted_only purity 60/60)
dieu_44_in_mapping: false   (sample tail addresses: …ICX-CONST/DIEU-41, ICX-CONST/DIEU-43 —
  DIEU-44 absent; heterogeneous/non-contiguous DIEU keys intentional & reconstruction-closed)
provenance: 100% rows bound to source_document_version_id icxconst-008a06…
sample_addresses: ICX-CONST/NT-1, ICX-CONST/NT-2, ICX-CONST/NT-3, …, ICX-CONST/DIEU-41, ICX-CONST/DIEU-43
per_row_fields: { canonical_address, level, effective_status, source_span{line_start,
  line_end, span_sha256}, content_hash(=span_sha256), provenance.source_document_version_id }
note: iu_mapping carries NO title/body — those must be deterministically derived by the
  future writer from the pinned snapshot region via source_span (see doc 4 OD-W9).

4. idempotency_keys_preview + write_set_preview

idempotency_keys: 60 entries · 60 DISTINCT (OD-1 = sha256(canon(source_document_version_id,
  canonical_address, content_hash)); human/scenario labels intentionally excluded)
write_set_preview.jsonl: every row "preview": true, "persisted": false (nothing inserted);
  table tally = { manifest_envelope: 1, manifest_unit_block: 60, cut_change_set: 1 }
IMPORTANT (feeds W-track): the write_set_preview models the v0.4 ledger families
  (manifest_envelope/manifest_unit_block/cut_change_set) — NOT the production
  public.information_unit + unit_version birth model. The production-truthful row-set is
  the writer's responsibility (doc 3/4); the cut-plan PLANNER preview is the per-IU
  identity/idempotency basis, not the production write shape.

5. Determinism

two independent runs (separate out-dirs, same pinned manifest) ⇒ identical
cut_plan_digest_sha256 edcae74f… ⇒ re_run_equal=true. Also equals the prior in-test S2
value ⇒ cross-session/cross-environment determinism confirmed.
