Semantic Patch Replay Handoff

The safe sidecar replay that turns deterministic patches into runtime-prep rows.

Ali Mehdi Mukadam · co-authored with Codex · branch ali/personalization-engine-mission-2026-06-09

The Single Idea

The deterministic semantic patches now replay into separate local runtime-prep artifacts. Source rows are untouched, but the engine room has concrete packet-hardening, caveat-serviceable, source-ref-rerun, and hold files.

01 · What Changed

Replay Without Mutation

The repo now has semantic_patch_replay.py, a CLI command, and tests. The command writes new validation artifacts and does not overwrite source title rows.

Where to Continue

  1. Build packet-hardening intake from semantic_patch_replay_v1_packet_hardening.jsonl.
  2. Build caveat-service runtime fixtures from semantic_patch_replay_v1_serviceable_with_caveat.jsonl.
  3. Attach the one source-ref candidate and rerun semantic harvest.
  4. Mine the 34 hold rows across the harvest source map.
  5. Expand replay beyond the 1,000-row sample toward the full serviceable title universe.
06 · Resume Commands

Regenerate Replay

cd /srv/aina/aina-data-engine-room
.venv/bin/aina-data-engine --root /srv/aina/aina-data-engine-room semantic-patch-replay
Where to start

Start with packet-hardening intake, because the replay artifact now provides a clean local candidate file.
