Fuaran.Compute.ColumnOps 0.42.0

Fuaran server-driven interactivity — the transport-agnostic core for the third client tier (HTMX / LiveView / Blazor-Server-shaped): the closure-free DomPatch + ClientEffect wire vocabularies the generic JS shim applies, the TreeOp→DomPatch lowering, the per-connection driver, and the IFuaranLiveChannel transport seam. Keep the Elmish update loop on the server; ship ~nothing to the browser. No platform-SDK dependency. Apache-2.0 licensed.

Fuaran server-driven backend 2 — one bidirectional WebSocket channel over ASP.NET. The lower-latency transport for measured high-frequency interaction (per-keystroke, drag, live cursors). A first-class second backend whose structural identity to the SSE backend (differing only in channel + endpoint glue) is the architectural-integrity check that IFuaranLiveChannel is genuinely transport-neutral. No platform-SDK dependency. Apache-2.0 licensed.

Fuaran server-driven backend 1 (v1 default) — SSE-push + POST-receive over ASP.NET. The thin transport glue around the Fuaran.UI.ServerDriven core: an SSE IFuaranLiveChannel, the POST inbound parser, the connection registry, and the GET-stream / POST-event endpoint wiring (mapFuaranLive). Default because SSE+POST rides natively through proxies/CDNs/WAFs, gets per-event HTTP governance for free, and maps reconnect 1:1 onto the journal via Last-Event-ID. No platform-SDK dependency (the SSE framing is self-contained). Apache-2.0 licensed.

Fuaran.UI.Program — the UI adapter for the domain-generic bounded program core: the UI witness (the UI tier's action union, node tree, binding store, tree-ops and client effects seen through the core's witness contract), the pre-0.6.0 names as aliases over it, and the UI transport loop (the bounded driver, its channel glue and the client runtime). Fable-clean. Released with the Fuaran.UI tier, in its version line, and built against the core's released packages (its previous package id, retired in fuaran#2022, last released 0.7.1 beside the core). Apache-2.0 licensed.

Fuaran.Compute.Conformance — the law families over the dataframe layer, beside the Fuaran.Core.Conformance kit they extend: transform parity against the DataFrame reference evaluator, the columnar op-algebra and op-stream (ColumnOps), incremental evaluation (evalFrom and the IncrementalDelta equivalence family), params and slot params, the static output-schema walk, the pinned evaluation clock, and aggregate-versus-GroupBy parity. The families ship in module DataFrameConformance; the pre-split Conformance.* spellings forward to them (marked for removal in Phase 258). FSharp.Core only, Fable-clean.
