IU Core MVP Sandbox — 01 Precheck Live Repo + Remote

Date: 2026-05-21 · Macro: v0.6-iu-core-mvp-sandbox-execution-hardening-rollback-drill Branch 0. Host/repo/remote precheck. No mutation in this branch.

Host

• Host = MacBook dev host Nguyens-MacBook-Air.local (Darwin 25.5.0, arm64), user nmhuyen. Correct execution environment — not VPS/Contabo.

Repo

• Path /Users/nmhuyen/iu-cutter-build/repo/iu-cutter — exists.
• Branch main. HEAD = d22e361 — matches the expected commit from the prior authoring macro. Working tree clean (no uncommitted changes at start).
• git cat-file -t d22e361 = commit — present and reachable.
• Recent log: d22e361 (iu-core authoring) ← f111d4a (O10) ← fdcf580 (O8F) ← cad989a (O8D) ← 703559c (O8A).

IU-core package present at d22e361

• sql/iu-core/ — 5 forward + 5 rollback + README.
• cutter_agent/iu_core/ — idempotency.py, tree.py, structure_ops.py.
• tests/test_iu_core_ddl.py — 33 tests (pre-macro baseline).

KB access

• agent-data KB reachable. The 11 authoring reports were read from knowledge/dev/laws/dieu44-trien-khai/v0.6-iu-core-mvp-pg-native-parent-child-structure-ops-authoring/ (reports 03, 04, 08, 10, 11). GPT session handoffs were NOT used as input.

SSH / VPS

• ~/.ssh/config alias contabo → 38.242.240.89. The brief name vmi3080463 is the VPS hostname, not an SSH alias.
• ssh contabo OK — remote hostname=vmi3080463, user root. Docker reachable; 10 containers running incl. a pg-restore-test-* candidate.

Verdict

Precheck PASS. Host correct, repo at expected d22e361, KB + VPS reachable. Proceed to sandbox discovery.
