Arc 4 stage 1 (docs/theme-faces-framing.md, revision 4). Faces are
theme entries under the reserved ui/ui.* namespace -- zero new Lua
API. Theme::face() resolves with the dotted-prefix walk but never
falls back to default_style; each face applies owns-surface within
its stage-1 component mask, identical on both frontends.
Substrate: two monotonic theme mutation counters (syntax/face) with
transactional set/merge/clear/default (parse before locking, commit
all-or-nothing, bump from the prior value); the StyleGate and the
minimap summary key on the counters -- fixing the pre-existing bug
where a mid-session pmacs.theme.set never re-shipped StyleSpans --
with the summary gaining payload-equality suppression that still
advances its key on computation.
Wire: InstanceMessage::ThemeFacts appended after CompletionPopup
(postcard discriminants are ordinal; a byte pin guards placement),
PROTOCOL_VERSION 15 -> 16, daemon-gated >= 16, one authoritative
table per attachment (None-seeded baselines), TUI silent-drop arm.
Grid: paint_frame resolves ui.modeline / ui.statusline /
ui.minibuffer(.candidate) / ui.gutter / ui.selection faces;
SearchView and DiagnosticView take the theme handle through the real
attachment paths (EditorCore injection, install_diag threading); the
canonical severity color resolves ui.diag.* with the Default ->
built-in policy that keeps the minimap presence encoding sound.
GPU: exact-name face table applied per draw with the Q#TH5 Default
mapping (plain text / window bg, reverse swap), local/peer wash
split, candidate-dropdown glyph site, and the status-band
shaping-cache invalidation without which a diag-face recolor with
constant counts kept stale counter colors.
Tests: 18-test acceptance suite (grid, wire, daemon gate, atomicity,
monotonicity, late join), 7 GPU headless tests incl. decoded vertex
colors, units for the face walk / transactional commits / producer
caches; protocol pins for v16 + the CompletionPopup byte pin.
Bites vs 3cbb9de (scripts/bite): semantic_render.rs (8 runtime test
failures), editor.rs (5 runtime), daemon.rs (v15 gate, runtime);
lua_bindings/mod.rs, pmacs-gpu/main.rs, search.rs, diag.rs, and
highlight.rs bite as compile failures (weaker evidence, disclosed).

New InstanceMessage::FileStyleSummary { buffer_id, generation, lines:
Vec<Style> }: a coarse whole-file styling summary for a Zed/VSCode-
style minimap, resolving the design note's Open Q#2. One dominant
Style per source line (by byte count across the producer's current
spans); the frontend maps minimap rows to one or more lines.
Producer scoped_file_summary reuses scoped_style_spans with a whole-
buffer synthetic viewport, so policy A's authority pick (tree-sitter
for grammar-backed languages, LSP semantic tokens otherwise) is
inherited automatically — no separate styling path. file_style_summary_msg
is keyed on the buffer's CRDT generation: an idle buffer at the same
generation pays nothing (the whole-file summary is the expensive bit
on large files, so re-emit only after edits). First frame for a
buffer always emits; the existing first-frame test updated to expect
3 messages (StyleSpans + Decorations + FileStyleSummary).
Per-line dominant style is the v1 representation. Future refinements
(fixed-N bands; whole-file RLE style runs) are recorded in the design
note as straightforward extensions if a real frontend prefers them.
Structural gating same as the other semantic families: the daemon
only constructs a SemanticRenderState for sessions that negotiated
semantic_render, so non-semantic sessions never receive it. Grid TUI
adds the variant to its ignore list. Round-trip fixture covers it.

scoped_inline_adornments (free fn, mirrors scoped_style_spans) reads
the inlay-hint store via for_uri and maps each InlayHint to an
InlineAdornment { at, AtOffset, Text{padded label, default style} },
clipped to the declared viewport (anchor in [vis_start, vis_end)).
Step 0 established inlay columns are already byte offsets by the time
they reach the store (inbound_converted rewrites the Position-shaped
InlayHint.position), so line_col_to_byte is exact with no per-server
encoding — unlike semantic-token styling.
inline_adornments_msg does the suppression: the InlineAdornments wire
variant has no generation/full/segments, so this is M11.2-level only
(whole-set re-send on any change, nothing when byte-identical, and
never an empty frame when there is nothing to say — no spam).
Tests: clip-to-viewport + padding + AtOffset, suppress-then-resync,
no-emit-without-hints; the old never-emitted invariant is split into
block_adornments_and_fold_state_still_never_emitted (Block/Fold are
still unwired) plus inline_adornments_not_emitted_without_hints.
assert_semantic_only now admits InlineAdornments.
Step 5 (folded): docs/semantic-frontend-protocol.md moves StyleSpans
(policy A) + InlineAdornments out of "declared, not wired", and adds
two deferred Open questions — per-byte tree-sitter/LSP blend, and
multiple-servers-one-URI.

The spec the M11 arc (M11.1–M11.5) implements; all five CHANGELOG
entries reference it. Status header updated from "post-v1.0 design
draft, no code" to an implementation map against the arc, so the
landed doc is not self-contradictory. Design body unchanged; the
"Open questions" remain open by design.
