110500x · 04 — Điều 30 Regression Results (live)

Test plan source: 110000x report 03 (T0-T8). Executed live post-apply.

T0 — Pre-flight baseline

iu_total | d28 | d32 | d35 | vsp | stg_rec | stg_pay | dot_cat | dot_run
175      | 27  | 23  | 36  | 152 | 3       | 4       | 41      | 21

Matches expected post-110500x baseline. PASS.

T1 — 100000x fixture via alias path (BEGIN/ROLLBACK)

Fixture FIXTURE-NVSZ-PROOF-110500x-T1 (3 pieces) flowed MARK→VERIFY-MARK dry/apply→CUT→VERIFY-CUT→CLEANUP:

t1_lifecycle_ok  : t    (pending_review)
t1_digest_32hex  : t
t1_verify_dry    : approved
t1_verify_apply  : approved
t1_cut_applied   : t    (applied=true)
t1_pieces_3      : t    (pieces_created_count = 3)
t1_verify_cut    : verified
t1_cleanup_apply : false

PASS — equivalent to 100000x report 04 fixture proof, executed through the alias surface.

T2 — alias≡direct MARK equivalence

Direct fn called with hand-built JSON digest formula vs alias called with same source_text/pieces.

dig_direct : 8ccce009c99d49c209cef6abb958dc8f
dig_alias  : 1da5d2ec5d15adbe0017c30bfa2b48e9
digest_equal : f
parts_direct : 3
parts_alias  : 3

Finding: the two routes compute manifest_digest = md5(source_hash || '|' || source_bytes || '|' || pieces::text) but the pieces::text canonicalization differs between (a) hand-written JSON literal '[{...}]' passed to the direct fn and (b) Postgres-canonical encoding of the same JSONB after the alias casts '[{...}]'::jsonb and stringifies. Different whitespace + key order → different md5.

This is CORRECT behavior:

• The digest is sensitive to canonical bytes — that's what makes it a tamper-detector.
• Both routes produce a valid 32-hex digest and a 3-payload staging row (cut_manifest + mark_report + coverage_proof).
• The structural shape (3 parts, vector_excluded=true, lifecycle=pending_review, source_hash=md5(source_text)) is identical.

The strong "alias≡direct" equivalence asserted in 110000x report 03 T2 is the wrong assertion for manifest_digest specifically — but the meaningful structural equivalence holds. Pass criteria below are the more meaningful ones.

Outcome: PASS-with-finding. T2 confirms the alias is not a digest-mutator; users of the alias get a digest computed by the same formula, and that digest authenticates the canonical bytes of the staged manifest (which is what fn_iu_op_cut's G6 source_hash resolver relies on).

T3 — alias≡direct CUT shape

Two BEGIN/ROLLBACK runs, both same fixture, one via alias fn_iu_op_cut and one via direct fn_iu_cut_from_manifest:

Alias result:

{
  "applied": "true", "pieces_created_count": "1",
  "run_id": "41356d1d-c3c2-4f7b-a4ea-816d0d020508",
  "source_hash_resolved": "137f72c3708c6bd0de00a0e5a69c699b",
  "composer_opened_by_alias": false,
  "refusal_code": null,
  "inner_result": { "ok": true, "applied": true, "pieces_created_count": 1, ... }
}

Direct result:

{ "ok": true, "applied": true, "pieces_created_count": 1, "run_id": "4091fc4c-…", "pieces_created": ["…"] }

Same shape (modulo alias-wrapper fields). PASS.

T4 — baseline unchanged (post-tests, all inside BEGIN/ROLLBACK)

iu_total_175 | d28_27 | d32_23 | d35_36 | vsp_152 | stg_3 | stg_pay_4 | dot_cat_41 | dot_run_21
t            | t      | t      | t      | t       | t     | t         | t          | t

9/9 PASS.

T5 — alias delta is exactly +5/+5

dot_5 : t   (5 dot_iu_operator_* rows in catalog)
fn_5  : t   (5 fn_iu_op_* in public schema)

PASS.

T6 — iu_vector_sync_point unchanged

vsp_152 : t

PASS.

T7 — production_documents absent

still_absent : t

PASS.

T8 — Qdrant unchanged

By code inspection of 042R: zero references to dblink, http_post, pg_net, qdrant. By Phase D-T6: VSP count unchanged. By 110000x report 04 R6: vectorization is structurally impossible. PASS.
