fix: resolve B-0357 ID collision#2263
Conversation
Two items had id: B-0357. The Z3 tautology replacement (this session) keeps B-0357. The semiring-parameterized weight item becomes B-0367. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

This change adds B-0367 as a new file but leaves docs/backlog/P1/B-0357-first-class-uncertainty-semiring-parameterized-weight.md in place, so the same backlog item now exists twice with identical content/title under different IDs. Because backlog automation enumerates every docs/backlog/P*/B-*.md file, this creates duplicate planning entries and still leaves the original B-0357 collision unresolved against B-0357-replace-tautology-z3-agenda-proofs-with-real-verification.md.
Useful? React with 👍 / 👎.
Rename semiring item to B-0367 to avoid duplicate IDs.
