Record Cut 5 landed: the commit profile is collapsed

TypedCommitStore, its const, its validator and the parameter are gone, with
nothing of the profile shape kept. The Mind receipt digest was proven unmoved
by running the pinning test at the base commit in a detached worktree, not by
a value captured from the new code.

Three corrections stand: ruling 20's uniqueness-ordering half had no named
test until this cut added one; the Deletes table's line anchors were stale by
26 lines, so later cuts should re-anchor before trusting a line number here;
and the subtraction estimate missed the test rewrite the Keeps list implied.

+    validation-before-replay, so the uniqueness-ordering half of S6 was
+    unpinned. Cut 5 added a test for it rather than leaving half the invariant
+    on trust.
+11. **The Deletes table's line anchors were stale by 26 lines**, written against
+    `5fb4eb22`. Matching was done by content. Later cuts should re-anchor before
+    trusting a line number in this map.
+12. **The subtraction estimate was −46/+8; the actual is +172/−122.** The
+    owner-side collapse matched; the overshoot is the test rewrite the ledger
+    never priced, because the Keeps list demanded three rules stay pinned while
+    the tests that pinned them died with the abstraction. Carrying cost still
+    falls: one struct, one const, one fn, one parameter and five arguments gone.

 **Soul's second pass corrected Self's record.** Self had written that a
 mutation reported a verdict it never earned. The committed script already threw
 on a missing anchor, the affected mutation existed only in a working copy, and
