Crate nmp_threading 

nmp-threading — reply-convention-agnostic timeline grouping.

Owns the kind-agnostic Grouper that collapses reply chains into Twitter-style stacked-module blocks, plus the trait surface (ParentResolver) and value types (ThreadPointer, ModulePolicy, TimelineBlock, GroupDelta) consumed by per-NIP wrapper view modules. It also owns the generic e-tag threading projection family (nmp.threading.graph.*) for consumers that need a reactive read model over a caller-supplied event scope. Depends only on substrate crates — no kind numbers, no app nouns.

• nmp-nip01::Nip10ModularTimelineView wraps this for NIP-10 kind:1.

See docs/decisions/0072-runtime-capability-and-shell-boundary.md and docs/architecture/crate-boundaries.md for the sibling-crate packaging rule.

Modules

block

TimelineBlock — the grouper’s output unit. A timeline payload is a Vec<TimelineBlock>; each block renders either as one standalone event card or as a Twitter-style stacked module with a connecting vertical line.

etag

Kind-blind resolver for marked/positional e tag reply/root grammar.

grouper

Grouper<R> — kind-agnostic timeline grouping. Given a stream of KernelEvents and a ParentResolver, emits a Vec<TimelineBlock> where reply chains collapse into Twitter-style modules.

ownership

Compiled ownership descriptor for crate-ownership reports.

pointer

ThreadPointer — what a reply / comment is anchored to.

policy

ModulePolicy — knobs for the grouping algorithm. Spec carries one per view instance so the same crate can serve different threading styles (tight modules vs. longer ancestor chains) without an algorithmic fork.

projection

Reactive threading graph projection.

resolver

ParentResolver — per-NIP plug for the kind-agnostic crate::Grouper.

runtime

Host wiring for the nmp.threading.graph.* read model family.

wire

Typed FlatBuffers wire codec for threading graph snapshots.
