Beyond the catalog

Extension API documents all 11 native FQ commands, FFKV storage administration, Bloom/Cuckoo filters, Count-Min Sketch, Top-K, t-digest and additional JSON arithmetic. Container command roots are not counted as extra catalog entries.

Reading command pages

• “Upstream since” is a Redis/module version, never an ffkv release. Complexity and metadata flags are upstream reference data, not ffkv benchmarks.
• Syntax follows the canonical catalog with explicit command-name typo fixes. The empty FT.AGGREGATE grammar is filled from implementation and BDD sources.
• BDD examples are JSON argument vectors extracted safely from actual feature docstrings, including actual Scenario Outline rows. Fixture tokens and base64 payloads remain explicitly identified.
• Listed scenarios are source coverage, not a test execution claim by the docs build. Error assertions are retained as errors. Setup and multi-connection order remain in the named feature.
• Need a running-server view? Use COMMAND INFO, COMMAND DOCS, COMMAND LIST and COMMAND COUNT.

Generation is offline and requires only Node: npm --prefix apps/docs run generate. Sources are src/command_catalog.json, src/command_metadata.json, the Rust extension registries and tests/bdd/features.
