Full core restore and SolrCloud collection backup/restore cycles are integration-tested on Solr 8.11.4/9.11.0/10.1.0 using local filesystem repositories and shared SolrCloud storage. See [backup and restore docs](backup-restore.md). |
 | Replication | `replication(command, params)`, `replicationFile(params)`; exported command-specific parameter and response models | V1 ReplicationHandler commands for index version, details, file list, leader/follower control (fetchindex/abortfetch across Solr 8/9/10), core backup/restore/status/delete, and raw file-content streaming. Integration coverage includes core backup/restore cycles on Solr 8.11.4/9.11.0/10.1.0. A disposable two-core leader/follower fetch using `fetchindex` and follower query read-back passed the full standalone/security matrix on Solr 8.11.4 / 9.11.0 / 10.1.0 (CI #640). Abort and polling lifecycle behavior remains unit-only. See Issue #95 and [replication docs](replication.md). |
 | Streaming Expressions | `stream()` | Sends `expr` with `wt=json` and parses the complete JSON response through the shared transport. It is not an incremental tuple-stream parser: no chunk-boundary protocol or memory-bound/backpressure guarantee is claimed. SolrCloud search is integration-tested on pinned Solr 8.11.4/9.11.0/10.1.0; unit tests cover JSON parsing, caller cancellation during body consumption, and cleanup after body-stream errors. See [Streaming Expressions](streaming.md) and Issue #93. |
-| Export | `export()`, `exportStream()`; exported `SolrExportParams`, `SolrExportSort`, and `SolrExportFieldType` | Export requests require typed `fl` and `sort` parameters, support repeated filter queries, structured or raw sort expressions, batch sizing, JSON/JavaBin writers, and an explicit custom-parameter escape hatch. The raw Response preserves backpressure-aware streaming; `exportStream()` exposes its byte body directly. Sort fields must be single-valued docValues fields (int, long, float, double, or string); field lists additionally support date and boolean and may be multi-valued. Solr 10.1 `includeStoredFields` support is exposed but requires version-specific verification. Existing raw Export response tests pass on pinned Solr 8.11.4/9.11.0/10.1.0; typed parameter serialization and streamed chunk consumption have unit coverage.

 ## Interpreting unverified operations
 
-An exposed action or parameter is not runtime-certified merely because it has a TypeScript model or serialization test. The API coverage page records the current triage of deferred and intentionally out-of-scope gaps. In particular, destructive Core Admin actions and cluster-wide Collections policy mutations remain unverified until isolated runtime evidence is added; SPLITSHARD/MIGRATE require the opt-in workflow in [#232](https://github.com/vsimko/node-solr-lambda/issues/232). Export `includeStoredFields` and ReplicationHandler abort/async lifecycle have focused verification issues [#258](https://github.com/vsimko/node-solr-lambda/issues/258) and [#259](https://github.com/vsimko/node-solr-lambda/issues/259).
