Conversation
Map duplicated logic across Rust, TypeScript, and Flutter, and classify what should stay dual-maintained versus what should merge. Links existing plans instead of restating them. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>
A cleanup is only allowed to land if characterization tests pin the old paths first, then scripts/consolidation-measure.py shows production lines in scope went down. Policy-splits (same shape, different CommitOpts) are called out so they cannot hide a behavior change. Co-authored-by: joepmeindertsma <joepmeindertsma@gmail.com>

scripts/consolidation-measure.py --self-test)Summary
Adds a duplication audit and a consolidation contract: a change that claims to remove a copy is not done until behavior is pinned on the old code and production lines in the declared scope go down.
planning/duplication-and-consolidation.md— map of copiesplanning/consolidation-contract.md— kind (delete-duplicate / policy-split / bind-twins / extract), required sequence, gatesscripts/consolidation-measure.py— numeric gate (production non-blank must drop; largest file and public items must not grow). Tests and generated files are excluded. Unchanged scope fails on purpose.Highest-leverage copies from the audit: three commit-ingest paths, Loro merge written twice,
protocol.rs↔ws-v2.ts, ontology URLs in three places, datatype tags at different times, search/blobs in the server crate, 9883 vs 9885.
