Merged with admin on local + CI evidence: `tests/unit/i18n-catalogs-no-duplicate-keys.test.ts` red on the tip (59 catalogs) → `pass 3 / fail 0` here; **API Route Typecheck passes on this PR** (it fails on every PR based on the current tip because of the duplicated `ERROR_TYPE_CONTRACT` import this removes); CodeQL, semgrep, Vitest fast-path, Docs gates, Change Classification pass. The remaining red checks (Fast Quality Gates, Merge integrity, Unit Tests fast-path 1/2/4) are the same inherited tip reds every PR on release/v3.8.51 shows right now — #13747 sweeps them. Both removed lines were byte-identical duplicates; nothing parsed or typed changes.
Search stats and recent searches stop surfacing ghost rows: NULL and `-` providers are always hidden, and, behind the new `SEARCH_STATS_HIDE_DELETED_CONNECTIONS` flag (default off), traffic of a keyed provider whose connection was deleted is hidden too. Totals use the same guard as the per-provider rows, so they always agree.
Maintainer rework before merge (kept the idea, no default behavior change):
- Keyless providers from the search registry (`duckduckgo-free`, `searxng-search`, anonymous `context7`) and providers served through a credential fallback (`perplexity-search` on a `perplexity` key) stay visible in both modes — the original filter dropped them because they have no `provider_connections` row.
- Tests use real registry ids and cover flag off (historical stats) and flag on, including the analytics route; #13281's changelog fragment restored.
Validated first on the combined board of all 38 PRs of this batch (10 merged as-is, 28 after the maintainer rework) on top of release/v3.8.51 c0f92ec: typecheck:core, check:open-sse-typecheck and check:dashboard-typecheck clean; ESLint clean on every changed file; file-size (rebaselined for the combined growth), complexity, cognitive-complexity, changelog-integrity, docs-counts, docs-sync, migration-numbering and i18n new-key gates green; 735 focused node:test cases with the only batch-caused failure (a flag-count assertion) fixed. Then re-validated alone on the fresh release tip right before this merge: ESLint on the changed files, typecheck:core, check:open-sse-typecheck, the file-size/complexity/changelog gates and this PR's own tests.
Thanks @maxmad64bis!
`error_type` becomes a versioned vocabulary: a failure the classifier cannot place is stored as `unknown` instead of NULL, and any stored value outside the vocabulary reads back as `unclassified` in the breakdown.
Maintainer rework before merge (kept the idea, no default behavior change):
- `PROVIDER_ERROR_TYPES` is `as const`, so `ErrorTypeContract` is a real union and the classifier functions return the narrowed type.
- The constants moved above the JSDoc that documents `getErrorTypeBreakdown`; the vocabulary SQL is built on first use so an import cycle cannot read it before it exists.
- Legacy NULL rows keep landing in the `pre_migration`/`unclassified` bucket without vanishing or double counting, and the log export / BigQuery row pass both NULL and `"unknown"` through unchanged — both covered by tests. Duplicate assertions removed; every seeded row is cleaned up in `finally`.

Validado numa worktree combinada com a onda de persistência desta leva sobre `release/v3.8.51`: check-file-size e check-changelog-integrity OK, typecheck:core limpo, check-api-typecheck OK (289), 70 testes focados no runner Node e 1 no vitest, todos verdes.
"Zeros continuam zeros, latências ausentes continuam ausentes, falhas pré-coluna ganham o próprio balde" — a distinção entre ausência e zero é o miolo aqui. Um install novo mostrando 0ms como se tivesse medido é pior que mostrar nada, porque parece dado.
**Uma mudança minha na sua branch: a migration foi renumerada de 174 para 175.** A `174_server_tool_executions.sql` entrou no #12867, mergeado horas antes desta leva, então `174_call_logs_provider_stats_indexes.sql` colidia. Renomeei o arquivo e ajustei o rótulo do teste ("migration 174 creates..." → 175). Confirmei que não sobrou prefixo duplicado em `src/lib/db/migrations/` e revalidei o `call-logs-provider-stats`: 4/4.
Os dois índices compostos são a parte que paga a longo prazo — rollup por provider parando de varrer a tabela.
Validado no worktree combinado: mesmos gates + testes focados verdes. Extensão opt-in bem desenhada sobre #10909 (dimensão de uso real via call_logs). CI vermelho é o base-red já rastreado em #9985.
Merged — validated together with a batch of related maxmad64bis PRs in one combined worktree (typecheck:core clean, complexity/cognitive-complexity/file-size/changelog gates green, focused tests passing). Thanks for the contribution!
