 - **Contract:** `set_rules::Rule::{EmptyMeasure, CountAll}` added (catalogue 8 rules). **relalg:** `normalize::symbolic` delegates to `set_rules::rewrite`; crepe's symbolic answers follow through `lance_graph_relalg::run`. Entry `entries/2026-10-21-d-ra-2-relalg-symbolic-repoint.md`.

+- **Added:** `set_rules::Rule::{EmptyMeasure, CountAll}` (catalogue 8 rules); test `experiment_e_no_universe_refuses_the_range_rules`; entry `2026-10-21-d-ra-2-relalg-symbolic-repoint.md`. Also the #1651 board closeout (D-CMR-6 Shipped, PR_ARC #1651).
+- **Locked:** `lance_graph_relalg::normalize::symbolic` decides through `set_rules::rewrite` under `Semantics::exact(n_rows)` and answers only a constant; `Min`/`Max` answer `None` only when their `Count` folds to 0. crepe's symbolic answers follow through `relalg::run`; crepe's join-body rewrites stay. `Count(∅)`/`Sum(∅) → 0` refuses `_sym` sums; `Count(All) → N` refuses no universe, bags, IEEE.
+- **Deferred / open:** `Min`/`Max` stay outside `set_rules::Measure` (empty answer is `None`).
+- **Confidence:** measured. set_rules 25, relalg 26 unchanged, crepe-plan-probe 46 unchanged (re-run on the rebased head incl. #1653), contract lib 1,547; disable runs show relalg's answers depend on the contract rules; each new guard red when removed; Codex's #1654 finding (range no-universe negative control) fixed with a test.

 # 2026-10-21 — D-RA-2: relalg's symbolic answers repointed onto `contract::set_rules` (crepe through relalg)
 
-**Status:** TEST-PINNED, in PR (branch `claude/eager-albattani-iufugq`). **Basis:** six-decisions §2 ("D-CMR-6 publishes the catalogue → repoint crepe"); D-RA-2 option A; claim EXO-50 `session_013z2e1YXkm6o6HNrDn5BPWA/019`.

 - **What was duplicated:** `lance_graph_relalg::normalize::symbolic` decided `Count(∅) = 0`, `Sum(∅) = 0`, `Min/Max(∅) = None` and `Count(All) = n` by matching `Rel::Empty` / `Rel::All` locally — single-table measure identities outside the contract.
 - **Contract (`set_rules`, two rules added):** `EmptyMeasure` (`Count(∅) → 0`, `Sum(∅) → 0`; refuses `_sym` sums, whose empty sum is a sentinel) and `CountAll` (`Count(All) → N`; refuses no universe, bag, IEEE). The catalogue has 8 rules.
