Dedupe

Produce a proof-rich duplicate report for a bounded collection. Keep discovery, grouping, canonical selection, mutation, and verification separate so unique information cannot disappear silently.

Runtime composition

Apply these owners for every dedupe task. Load their current instructions instead of copying their procedures here.

1. Load always-current-datetime and acquire its clock anchor before a user-facing reply. Query runtime time again only when freshness, age, redirects, file times, or a newest-item tie-breaker affects the decision.
2. Load starting-point. Fix the requested result, bounded inputs, authority, required evidence, unknowns, and forbidden outcomes.
3. Load outcome-bounded-work. Treat adapter steps as candidate routes unless a step protects identity, safety, authorization, reproducibility, or proof.
4. Load logic-audit. Audit identity rules, normalization, similarity thresholds, non-transitive pairs, conflicts, canonical tie-breakers, nulls, missing values, links, and edge cases before mutation and completion.

Stop with contract-unavailable: <skill-name> if a required owner cannot load. Never replace an unavailable owner with remembered text.
