19 — MCP-Readable Checkpoint Pointer

The full MCP-readable checkpoint for this macro is:

knowledge/dev/reports/architecture/checkpoint-rp-generator-parity-fix-contract-replace-ui-deploy-standby-2026-06-05.md

It contains: final status (PARTIAL), execution mode (EXECUTION, birth-free), the OOM crash incident (4 crashes, auto-recovered, no data loss, plpgsql-function fix), dual-path verification, AX-PROCESS generator fix, AX-PXT generator fix, generated contract v2, parity validation v2 (5/5 axes, 0 gap; substrate_parity false surfaced), autoscale dashboard v2 (GENERATOR_PARITY_PASS_OPERATOR_REPLACE_REQUIRED), the safe replacement decision (candidate only, no repoint), UI standby status (branch d04d8e5, blocked by git), deploy readiness guard (UI_DEPLOY_BLOCKED_BY_GIT, db_side_ready true), synthetic-axis relation, regression tests (6/6 with teeth), safety/no-fake audit (all unchanged), final verdict, exact blockers, and the next macro.
