FIX7 P0 — Dry-Run Staging Isolation Proof (2026-06-11)

• Authority: DRYRUN_NON_AUTHORITY. Machine form (byte-identical): fix7-p0-dryrun-staging-isolation-proof-2026-06-11.json = packet staging-isolation-proof.json.

Workspace /tmp/fix7p0-dryrun.<rand> created via mktemp -d on the local laptop (Darwin arm64). Isolation is PROVEN:

• is_production=false; not a production host.
• connects_to_production_pg=false, connects_to_production_directus=false, connects_to_system_issues=false, connects_to_registry_row=false.
• disposable=true; cleanup = rm -rf /tmp/fix7p0-dryrun.<rand>.
• evidence_capturable=true; all logs captured under the workspace.
• No mcp__*Incomex_VPS__* / query_pg / pg_schema / directus_* tool was invoked in the dry-run; the only KB calls were read-only fetches of governed seal/planning/canon docs.
• DR-2/DR-3/DR-4 mutations operated solely on /tmp temp files and were all rolled back.

Forbidden-surface non-mutation table: production, production PG, production Directus, registry-row, system_issues, REAL_RUN, QT001/apply, permit, activation, repoint, cutover — every one touched=false with the proof recorded in the JSON.
