1. Snapshot artifact exists exactly once

path: knowledge/dev/laws/dieu44-trien-khai/snapshots/constitution/constitution-normalized-17660443e0f23e99.md
pre_write_state: snapshots/constitution/ listed -> 0 items ; target -> 404
post_write_state: exists, revision=1 (single create; agent-data status=created)
duplicate_check: only ONE artifact at the checksum-addressed path; no second
  artifact, no alternate-prefix copy created
verdict: EXISTS EXACTLY ONCE

2. Path first16 matches checksum (QG3)

normalized_content_checksum: 17660443e0f23e994e1807cf8e22920951a9e70c598956dbd0e752f4f5cae80c
first16:                     17660443e0f23e99
filename:                    constitution-normalized-17660443e0f23e99.md
match: TRUE (filename prefix == first 16 hex of the region sha256)

3. Metadata checksum equals region checksum (QG7)

metadata.normalized_content_checksum: 17660443e0f23e994e1807cf8e22920951a9e70c598956dbd0e752f4f5cae80c
metadata.normalized_content_length:   17522
metadata.marker_counts:               { enacted:19, controlled_draft:1, draft:1, obsolete:1 }
recomputed_region_sha256 (sha256 of bytes strictly between BEGIN/END sentinels,
  sentinels excluded, no trailing newline):
  17660443e0f23e994e1807cf8e22920951a9e70c598956dbd0e752f4f5cae80c
recomputed_region_length:  17522
recomputed_region_markers: enacted 19 / controlled_draft 1 / draft 1 / obsolete 1
metadata_checksum == region_checksum: TRUE
metadata_length   == region_length:   TRUE
metadata_markers  == region_markers:  TRUE
region_checksum   == ratified_canonical (17660443…): TRUE

4. Normalized-content region rehash PASS

rehash_gate (CP-7): PASS
basis: cryptographic sha256 computed over the exact normalized-content region
  byte-source that was uploaded; equals metadata checksum, filename-prefix
  source, and the GPT-ratified canonical 17660443…/17522.
kb_round_trip_integrity: get_document_for_rewrite content_length = 19197 ==
  uploaded byte-source length 19197 (exact parity) ; metadata header verbatim ;
  exactly one BEGIN sentinel + one END sentinel ; region first/last lines exact
  -> persisted artifact is byte-faithful to the verified source (revision 1).
SC5_artifact_rehash_mismatch: NOT triggered
SC6_write_or_readback_failure: NOT triggered

5. No overwrite occurred (QG4)

collision_precheck: path absent (dir empty + 404) BEFORE write
write: first create -> revision 1
overwrite_attempted: FALSE ; delete_attempted: FALSE ; truncate/append: FALSE
SC1_existing_same_content: not applicable (path was absent)
SC2_existing_different_content: not applicable (path was absent)
write_once_convention: honored (single immutable checksum-addressed artifact)

6. No source seed / DML / dry-run / CUT / VERIFY executed (QG2)

source_document_insert:            FALSE
source_document_version_insert:    FALSE
dml_execution:                     FALSE

git_commit:                        FALSE
self_advance_to_E2_seed:           FALSE
only_writes_this_phase: 1 snapshot artifact (write-once) + 3 E1 reports

7. Quality-gate summary

QG1 refimpl.r1 not prose:                 PASS (doc3 rev3 canonical, KB SSOT)
QG2 no DML/seed/dry-run/CUT/VERIFY:        PASS
QG3 path includes first16 checksum:        PASS (17660443e0f23e99)
QG4 no overwrite:                          PASS (revision 1, path was absent)
QG5 marker counts 19/1/1/1:                PASS
QG6 checksum matches canonical pre-write:  PASS (17660443…)
QG7 readback region rehash == metadata:    PASS (== canonical)
QG8 report includes next recommended phase: PASS (see report doc 3)
QG9 STOP after 3 files:                    PASS (3 then STOP)

8. Statement

• Snapshot artifact exists exactly once at the checksum-addressed path; filename prefix == region sha256 first16; metadata == region rehash == ratified canonical 17660443…/17522/19·1·1·1; no overwrite/delete; no seed/DML/dry-run/CUT/VERIFY; refimpl.r1 (doc3 rev3) used.
• doc 2 of 3; STOP after 3 files → route GPT/User. Self-advance PROHIBITED (no E2 seed).
