 ## Session Log
 
+- **2026-04-11 Claude** `b3253f3..59331e5` (1 commit). Wired the DEV-LEDGER, added session protocol to AGENTS.md, created project-local CLAUDE.md, deleted stale `codex/port-atocore-ops-client` remote branch. No code changes, no redeploy needed.
 - **2026-04-11 Claude** `c5bad99..b3253f3` (11 commits + 1 merge). Length-aware reinforcement, project memories in pack, query-relevance memory ranking, hyphenated-identifier tokenizer, retrieval eval harness seeded, off-host backup wired end-to-end, docs synced, codex integration-pass branch merged. Harness went 0→6/6 on live Dalidou.
 - **2026-04-11 Codex (async review)** identified 2 P1s against a stale checkout. R1 was fair (extraction not automated), R2 was outdated (project memories already landed on main). Delivered the 8-day execution plan now in Active Plan.
 - **2026-04-06 Antoine** created `codex/atocore-integration-pass` with the `t420-openclaw/` workspace (merged 2026-04-11).
