Day 2 extractor eval baseline on a 20-interaction labeled set shows
0% yield / 0% recall / 0% precision. The 5 false negatives span
5 distinct miss classes, matching the pattern Codex's Day 4 hard
gate was designed to catch but arriving two days early.
No extractor code change on main. Day 1+2 artifacts committed on
working branch 'claude/extractor-eval-loop' at 7d8d599. Day 4
decision (keep rule-expanding vs prototype LLM-assisted mode) is
escalated to Antoine for ratification before Day 3 work touches
any extractor.

The ledger is the one-file source of truth for "what is currently
true" across Claude/Codex/human sessions:
- Orientation (live SHA, main tip, test count, harness state)
- Active Plan (currently Codex's 8-day extractor + harness plan
with hard gates and fail-early thresholds)
- Open Review Findings (P1/P2, status)
- Recent Decisions (bounded to last 20)
- Session Log (bounded to last 20)
- Working Rules (no parallel work, branching rule, P1 block)
Narrative docs under docs/ sometimes lag reality; the ledger does
not. Every session MUST read it at start and append a Session Log
line before ending.
AGENTS.md: added a new "Session protocol" section at the top that
points at the ledger. Applies to any agent (Claude, Codex, future).
CLAUDE.md (new, project-local): project instructions for Claude
Code in this repo. Points at DEV-LEDGER.md and AGENTS.md, spells
out the deploy workflow and the Claude/Codex working model.
