O8C Report 01 — Precheck-live & deployed-state ratification (G0/G1)

  • macro: v0.6-o8c-real-db-rollback-proof-readiness
  • date_utc: 2026-05-21 · host: vmi3080463 (Contabo · 38.242.240.89 · Linux x86_64)
  • gate covered: G0 PRECHECK-LIVE
  • result: G0 PASS — deployed O8B state ratified as state-of-record

1. Host & path confirmation

running_on:        vmi3080463 / Contabo VPS (correct host for live-DB + deployed smoke)
active_v0.6_path:  /opt/incomex/dot/iu-cutter-v0.6            present
backup_v0.6_path:  /opt/incomex/dot/iu-cutter-v0.6.pre-o8b-20260521T053334Z  present
v0.4_skeleton:     /opt/incomex/dot/iu-cutter                present

2. Active tree == O8B deployed artifact (integrity proof)

The active tree carries DEPLOY-MANIFEST.txt — the O8B artifact manifest with an 82-entry per-file sha256 list. Verified on this host:

sha256sum -c (82 manifest entries)  ->  82 OK, 0 FAILED
artifact:        iu-cutter-v0.6-703559c.tar.gz
artifact_sha256: db3f48b663d3f1df87fd2b52d1757b6b646b688ebd71986c25ab4964e4c64738
source_commit:   703559c91b819a6ab70fffc6105776014f7a6a56  (branch main, parent 6625f76)
file_count:      82  (all 82 sha256-verified against the manifest)
built_host:      Nguyens-MacBook-Air.local (developer Mac / SSOT)

This exactly matches the O8B-retry PASS evidence (KB …/reviews/dot-iu-cutter-v0.6-o8b-reconcile-deploy-live-wiring-pass-gpt-ruling-2026-05-21.md and …/v0.6-o8b-retry-mac-reconcile-deploy-live-wiring/09-final-o8b-retry-report.md). Conclusion: the deployed Contabo v0.6 active path == O8B deployed state-of-record. O8B is ratified.

The backup …pre-o8b-20260521T053334Z is the prior O6B artifact (6625f76), retained as the rollback anchor.

3. Kill-switch OFF

cutter_agent/orchestrator/__init__.py:35  __execution_enabled__ = False
execution_enabled()                       -> False  (function, call-time)

4. v0.4 skeleton untouched

dot_repo_HEAD:        e93424b5ff7fa5e4b8406131977ce4339cd0856a  (unchanged)
v0.4 source mtimes:   all 2026-05-20 06:21 — no source file modified
caveat:               one __pycache__/*.pyc regenerated on import — bytecode
                      cache only; no v0.4 source byte changed
