1. Dual result (both PASS-criteria branches resolved honestly)

CAPABILITY_1_CUT_PLANNER (S2/cutplan):
  result: READY_FOR_S2_COMMIT_REVIEW  (== READY_FOR_CUT_PLANNER_COMMAND_REVIEW —
          S2 is a planner, not a writer)
  evidence:
    - tests.test_cutplan_snapshot 15/15 GREEN (this session, no DB env, net-zero)
    - reproduces the accepted pinned identity (manifest digest 9d908a62…, file sha
      7d56f3ce…, candidate_count 60, Điều 44 excluded, reconstruction_ok, 60 distinct
      OD-1 idempotency keys) from the byte-exact fixture
    - fail-closed guard + determinism + stdlib import-isolation all proven by tests
    - py_compile OK; files byte-exact (cutplan 548eabc5… / test 06e871e7…)
    - the lone full-discover failure is PRE-EXISTING at ratified baseline afb7bfc
      (re-proven by moving S2 aside → still fails on dryrun.py:474); MARK was ratified
      on the targeted-suite gate (21/21, re-confirmed) with this same latent failure
  recommended_gate: R1 — ratify the targeted-suite commit gate; commit the 2 files
    as-is on the feature branch; track the security-test heuristic as a SEPARATE
    pre-existing remediation. (R2 remediate-first acceptable if GPT prefers.)

CAPABILITY_2_PRODUCTION_CUT_WRITER:
  result: BLOCKED_WITH_EXACT_IMPLEMENTATION_GAP
  exact_gap: GAP-W1 no manifest→information_unit/unit_version writer exists (cutplan is a
    planner whose preview targets the v0.4 ledger families, NOT the real schema);
    GAP-W2 manifest→IU field mapping undefined for the governed birth gate + N-2 unruled;
    GAP-W3 dot_config vocab prerequisites for ICX-CONST not confirmed/seeded;
    GAP-W4 cutter_exec/cutter_verify credential + production signing not built;
    GAP-W5 no separate production-write approval / governed VERIFY for birth model.
  gap_class: IMPLEMENTATION (schema now fully known — doc 3); not missing information.

2. Direction & answers to the macro-goal questions

direction: D (split: planner now, governed birth-gated writer next) — doc 4 §1.
S2_receives_manifest_9d908a62: YES (digest+file-sha+self-digest gated)
S2_identifies_60_candidates: YES (count gate + happy-path identity)
S2_granularity_NT/KT/DIEU: PASS-THROUGH only; N-2 IU-vs-container UNRULED (writer-design input)
S2_keeps_Dieu44/draft/obsolete_excluded: YES (mandatory flag + candidate guard + excluded-only)
S2_fixed_canonical_DIEU_addresses: YES (verbatim, dup-guarded; N-4 satisfied)
S2_output_sufficient_for_production_row_set: NO (wrong target schema — GAP-W1/W2)
S2_writer_or_planner: PLANNER (net-zero, preview-only)
S2_signing/credential/idempotency/rollback/verify: idempotency YES (OD-1);
  signing/credential/rollback/verify NONE (by design — a planner needs none)
production_information_unit: governed two-layer birth gate (L1 BEFORE field/vocab,
  L2 DEFERRED anchoring) + unit_version FK + dot_config vocab + UNIQUE(canonical_address)
  collision guard; 0 ICX-CONST rows today (clean insert)

3. Quality-gate mapping

QG1 current code/S2 state reconstructed                 : PASS (doc 1)
QG2 S2/cutplan capability reviewed from source           : PASS (doc 2)
QG3 production schema + writer gap (read-only)            : PASS (doc 3)
QG4 minimal-unblock direction chosen (A–E) + sequence     : PASS (doc 4 — Direction D)
QG5 progressed w/o production mutation (local CI run)     : PASS (15/15·21/21·128-1·py_compile;
     baseline-failure re-proven; S2 files byte-exact restored)
QG6 no invented production command / no pseudo-as-real    : PASS (only the existing S1
     contract shape referenced; production CUT WITHHELD)
QG7 commit-or-gap readiness stated clearly                : PASS (this doc §1)
QG8 STOP after upload, route GPT/User                     : PASS (this doc §5)

4. Explicit no-mutation statement

this_phase: ZERO production mutation. No CUT · no VERIFY · no DB/IU/Directus/vector write ·
  no source/version mutation · no code edit · no commit/push/merge/tag/deploy · no
  self-advance · no invented command. Local unittest runs were net-zero (no DB env).
  Only 5 KB documents created in v0.5-s2-to-cut-capability-readiness/. S2 files restored
  byte-exact (move-aside baseline proof only).
