1. API 1.1 (Stream C): canonical model universe, comparability-grouped leaderboards, deployments & cost, intelligence surfaces, admin workbenches

   …

   Existing routes (additive, v1 shapes kept): /models canonical universe + include=artifacts, family_id join, canonical licence
   matching, families/licenses/trust facets, /models/{slug} accepts artifacts and reports redirected_from; EntityDetail adds family,
   artifacts, deployments, identity, licence, openness, version_history, grouped benchmarks and runs in <= 4 connection groups; /stats
   adds organizations_total, artifacts, model_families, change_events_live_24h and counter definitions; /changes, /changes/daily
   ("Today in AI 2.0" with group_key folding), /timeline, entity timelines and /diff default to is_backfill=false on occurred_at
   (include_backfill, date_field restore v1); /benchmarks exposes family/variant/metric/direction/groups/trust_mix and resolves aliases;
   /compare groups benchmark dimensions by (benchmark, metric, config_key) with comparability, diff_only and mode; /prices adds
   family/org/modality filters and sort=cheapest_frontier; /prices/index becomes the AI Price Index; /providers adds distributions,
   30-day churn, organizations_covered, features_supported; /search compiler v2 (compiled/sort/residual/unrecognised, org verified
   against aliases, guarded casts, FTS fallback when pgvector is absent); /methodology, /trending?kind=.
   
   New routes: /benchmarks/{slug}/leaderboard, /benchmarks/{slug}/frontier, /benchmarks/matrix, /models/{a}/diff/{b}, /deployments,
   /cost, /cost/context, /frontier, /pareto, /pulse, /open, /find-a-model, /run-locally, /hardware/{slug}/fit, /families,
   /families/{slug}, /graph/explore, /time-machine, /claims/{id}, /entities/{slug}/claims, /entities/{slug}/provenance/{property},
   /licenses, /licenses/{key}; admin: /admin/quality, /admin/entity-resolution (GET + POST decisions via merge_entities mode= when
   available), /admin/anomalies, /admin/extractions/{snapshot_id}, /admin/quarantine (501 until services.canonical ships),
   /admin/audit, /admin/runs/{run_id}/rollback, /admin/cache/flush?after_run=1.
   
   Services: frontier.py (comparability groups, one-row-per-model leaderboards, frontier model set, leader_at), finder.py, pareto.py,
   cost.py, hardware_fit.py (architecture-aware KV cache, observed artifact sizes, multi-GPU), search.py v2, stats.py definitions.
   
   Security/perf: rate_limit("admin") before require_admin, failed-auth limiter 10/min/IP, x-forwarded-for only with AIA_TRUST_PROXY,
   set_limit GUC leak removed, weak ETag + Cache-Control + 304 on public GETs, admin audit log on every admin call. EXPLAIN ANALYZE on the
   production copy: every read path < 20 ms, no index migration needed.
   
   Docs: docs/API.md rewritten as the 1.1 contract (changelog, 1.1 additions, semantics changes, deprecations: none).
   Tests: tests/test_api_v11.py (contract) and tests/test_api_services.py (pareto, cost, compiler, hardware fit); 44 API tests pass.
