Completes the M11 arc with the consumer side. pmacs has no GUI
toolkit, so per the design note's testability strategy the
deliverable is the bounded testable glue, not a GPU renderer.
- src/semantic_client.rs (crdt-gated): headless SemanticClient
composing the BufferMirror rope replica (M10.10) with a tile-based
SemanticModel that reconstructs styling/decorations from the full +
dirty-segment deltas (M11.4). Emits FrontendEvent::Viewport;
read-back accessors (text / effective_style_at /
decoration_kinds_at / tile ranges). The M11.4 contract (segments
carry every current item intersecting their range) makes tiles
self-contained → incremental apply is per-tile replacement with
edge-clipping, no cross-span surgery. 7 unit tests.
- tests/m11_5_semantic_acceptance.rs: (a) reconstruction-equivalence
— incrementally-driven client asserted byte-for-byte identical to
a fresh full projection across a scripted viewport/edit/selection
sequence incl. a viewport jump (golden discipline, no snapshot
crate); (b) end-to-end — a real daemon routes StyleSpans/
Decorations to a semantic session (after it declares a Viewport)
and never to a grid session, CellDelta vice versa, validating the
M11.2 per-session projection through the socket.
Lib (1404 crdt / 1242 non-crdt) + integration green on both feature
flavors; clippy -D warnings clean on both.
M11 arc complete (M11.1–M11.5). Inline/Block/Fold/ResourceOffer
remain honest stubs pending their source features.
