- Bitsycore Reposilite repo in root + bridge publishing blocks
- per-host Bitsycore publish step in the workflow (task names derived
  from the matrix); releases repo has redeployment enabled so plain
  retries are safe
- workflow_dispatch fallback trigger (run with --ref <tag>)
- bridge: default skiko fork version -> 0.150.1-mingw.2 (republished to
  both repos so consumers need no GitHub Packages auth)
- README + bridge README: maven.bitsycore.com first, GH Packages fallback

 ## Module layout
 
 Library modules mirror upstream Compose Multiplatform's `compose/` tree.
-Only `:window` is the SDL integration layer ("Compose SDL" — SDL3 main loop)
-and lives under `compose/sdl/`.
+The SDL layer is two modules: `:sdl-core` (the NAKED sdl3 cinterop + platform
+primitives - zero Compose dep, like `skiko`) at `sdl/sdl-core/`, and
+`:desktop-native-window` (the SDL3 main-loop shell + app entry point) at
+`compose/desktop/native/window/`. `:ui` depends on `:sdl-core` and its renderer
++ SDL↔Compose bridges pick the cinterop from it.
 
 One Gradle module per upstream artifact; the directory mirrors the upstream
 `compose/` path, the gradle path is kept short (redirected via `projectDir`).

+# ROAD TO 1.0.0
+
+**Objective:** get ComposeNativeSDL3 **as close to upstream Compose Multiplatform as
+possible** - vendor every file we can instead of rewriting, stay performant, and look
+faithful (ideally pixel-identical across macOS / Linux / Windows). The port is already at
+99% upstream API coverage with maximal vendoring and no steady-state perf gap on
+macOS/Metal; the remaining 1.0.0 work is **cross-platform rendering fidelity** (Windows
+skiko-fork divergences), **completing native-actual stubs**, and the release mechanics
+(1.12.0-stable re-pin + WIN-SMOKE).
+
+**Status / handoff:** the macOS/Linux-verifiable work is done and committed on `main` (see
+**"Landed toward 1.0.0"** below - don't redo it). The remaining blockers need a **Windows host**
+→ jump to **"▶ Continuing on Windows (mingwX64) - START HERE"**. This file is self-contained: it
+has the build/run commands, the exact confirm steps, the macOS baseline data to diff against, and
+per-task fixes. So on Windows you can say **"continue PLAN.md"** and have everything.
+
+## Definition of done for 1.0.0
+
+- [x] No text tofu on any platform - Windows tab fix **CONFIRMED on-device** (§1a, 2026-08-04:
+      literal `\t`→space, no `.notdef`); CJK / color-emoji / control chars render clean too (§1c).
+- [x] Fork-vs-official divergence surface (FontMgr, gamma, ICU) **audited on native Windows**
+      (2026-08-04): metrics == JVM (§1b), FontMgr fallback works (CJK + color emoji, §1c), ICU
+      classification works (§1c). Net - the fork's Skia matches upstream; the only deltas are its
+      thin extern-C bindings, handled in shared Kotlin (LineMetrics reconstruction). No fork-side
+      fix needed for 1.0.
+- [~] Native-actual fidelity blockers closed: float pointer coords **DONE**, screen-reader
+      no-op **DONE**, text context menu **RECONCILED - already works** via the legacy path
+      (§2). Date/time localization is P1 polish (formatter already works).
+- [x] Vendor hygiene stays clean: zero drift (all 10 manual vendors match pin), zero
+      commonMain rule-1 violations, zero vendored files touched this session - verified via
+      `check-vendor-drift.py`.
+- [~] SDL static lib slimmed to the used subsystem surface (§3) - **DONE + verified on
+      macOS/Metal**; other hosts pending WIN-SMOKE.
+- [ ] Refs re-pinned to Compose **1.12.0 stable**, JVM parity versions bumped, WIN-SMOKE
+      fidelity pass green on a real Windows host.
+- [x] `CLAUDE.md` documentation map consistent with tree - line-1 typo fixed; the stale
+      historical docs `RENDERER.md` + `SKIKO-MINGW-FEASIBILITY.md` removed (current renderer
+      essentials inlined into CLAUDE.md, the rest is in git history); all dead doc links
+      (TODO.md / RENDERER.md / SKIKO) removed or repointed to PLAN.md.
+
+## Landed toward 1.0.0 (this pass - all build + run verified on macOS/Metal)
+
+Everything below is committed; details + file refs are in the sections that follow.
+
+1. **Tab tofu fix** (§1a P0) - normalize `\t`→space before shaping so the Windows fork
+   can't render `.notdef`. Platform-independent, length-preserving.
+2. **HiDPI caret quantization fix** (§2 P0) - pointer/wheel coords carried as `Float`
+   end-to-end instead of truncated to `Int`.
+3. **Screen-reader no-op** (§2 P0) - `LocalPlatformScreenReader` defaults to inactive
+   instead of throwing.
+4. **SDL slimming** (§3) - 10 unused subsystems disabled in `build-all.py`; 6 now-dead
+   macOS frameworks dropped from `sdl3.def`. Rebuilt; demo + apidemo link, demo runs.
+5. **Context menu reconciled** (§2 P0) - confirmed already working via the vendored legacy
+   path; the 3 "NOP" seams are vestigial (disabled new API) - misleading TODOs corrected.
+6. **`CDN_TEXT_METRICS` diagnostic** (§1b) - env-gated line-metrics dump; macOS baseline
+   captured, hypothesis sharpened (fork likely drops lineHeight leading).
+7. **Doc hygiene** (§5) - removed the stale historical `RENDERER.md` +
+   `SKIKO-MINGW-FEASIBILITY.md` (renderer essentials folded into `CLAUDE.md`; rest in git
+   history), fixed the `CLAUDE.md` typo + all dead doc links; extracted the fork
+   FreeType-scaler lead into §1c before deleting. Vendor drift verified clean.
+
+**Windows pass (2026-08-04, this host - DPR 1).** On a real Windows host at last: (8) tab fix
+**CONFIRMED on-device** (§1a); (9) vertical metrics **RESOLVED** - native `--metricsprobe` heights
+== JVM `--metrics` exactly, feared "dropped leading" DISPROVEN (§1b); (10) fork `LineMetrics.
+ascent/descent` mis-decode **FIXED in shared Kotlin** (`SkiaParagraphOps.lineMetrics()`, guarded
+no-op on official skiko) - repairs Windows caret/selection; (11) fork FontMgr/ICU **AUDITED** - CJK
++ color-emoji + control-char fallback all work → the "empty FreeType stub" fear DISPROVEN (§1c);
+(12) `FontRasterizationSettings.native.kt` verified to mirror upstream VERBATIM + given a
+`VENDOR-BASE` provenance line; rasterization stays upstream-faithful per-OS (user decision). Net:
+the fork's Skia matches upstream - the only deltas are its thin extern-C bindings, fixed in shared
+Kotlin, **zero fork rebuild**.
+
+**Still not done - WIN-SMOKE interactive + release** (§5): interactive caret-height check (the one
+behavioral consequence of the LineMetrics fix), the `PrintWindow` probe, `compileCommonMainKotlin
+Metadata`, apiDump + publish FROM Windows, and the Compose 1.12.0-stable re-pin. **Deliberately
+deferred** (large/structural, rationale in-section): RTL, `PlatformFontLoader`, grapheme source-set
+move, date CLDR, brush/gradient text - plus the big **vendor-the-upstream-skiko-text-engine
+refactor (§6)**, sequenced after these fixes land.

+
+## ▶ Continuing on Windows (mingwX64) - START HERE
+
+**Read this before doing anything.** This file is the single source of truth for the road to
+1.0.0. Everything in **"Landed toward 1.0.0"** above is **already implemented and committed on
+`main`** - do NOT redo it, just verify it on this host. Every open `[ ]` / `[~]` below is
+remaining work. The macOS/Linux side is done and verified; the remaining blockers need a **real
+Windows host** - the mingwX64 build cross-compiled from mac/Linux fails at cinterop, and the
+bitsycore skiko **fork** can only be rebuilt on Windows.
+
+**The Windows fidelity reference is skiko-on-JVM Compose Desktop on THIS Windows host**
+(`gradlew :demo:run` - also DirectWrite/system fonts), NOT macOS. mac↔Windows metric deltas are
+expected in upstream Compose Desktop too, so "matches Windows-JVM" is the acceptance bar, not
+"matches macOS".
+
+### Build / run (Windows shell, repo root)
+
+```bat
+gradlew.bat :demo:runDebugExecutableMingwX64      :: native demo (the port under test)
+gradlew.bat :apidemo:runDebugExecutableMingwX64   :: native apidemo (has the Session/Override buttons)
+gradlew :demo:run                                 :: JVM Compose Desktop = the FIDELITY REFERENCE
+gradlew :apidemo:run                              :: JVM apidemo reference
+```
+
+- The bridge plugin auto-drops `skiko-windows-x64.dll` next to the exe (`installWindowsSkiaDll`).
+  Fork coords `com.bitsycore.skiko:skiko:0.150.1-mingw.1` (override `-PskikoMingwVersion`).
+- `:demo` CLI flags (native AND jvm): `--screen=<Name>`, `--screenshot=<path.bmp>` (capture at
+  quiescence then quit), `--gpu=auto|software|skia.opengl`. `CDN_TEXT_METRICS=1` env var dumps
+  text metrics (§1b). `CDN_PROFILE=1` frame profiler. `:apidemo` has NO screenshot CLI - drive it
+  by hand for the button-metrics visual.
+- If an IC-cache error appears after any module churn: delete `demo\build\kotlin-native-ic-cache`.
+
+### ✅ Windows session results (2026-08-04, this host - DPR 1.0)
+
+Items 1–3 below are **DONE + verified on the shipped mingwX64 demo binary**; findings folded into
+§1a/§1b/§1c. Only 4–5 (WIN-SMOKE interactive gate + apiDump/publish) remain. TL;DR:
+
+- **§1a tab fix - CONFIRMED.** `--screen=BasicText` with `"start>a\tb<end\tcols\tand\tthere"`
+  rendered `start>a b<end cols and there` - every `\t` a SPACE, zero `.notdef`. (Structural proof
+  too: the whole module has exactly 2 `.addText(` sites, both `shapedText`.)
+- **§1b vertical metrics - RESOLVED, the feared bug is DISPROVEN.** Native `--metricsprobe` vs JVM
+  `--metrics` (same host, NotoSans, density 1): **every paragraph height + non-M3 baseline matches
+  JVM EXACTLY** (size 11→24). Leading is NOT dropped. Two residual deltas found (details in §1b):
+  (a) the fork's `LineMetrics.ascent/descent` are mis-decoded - **fixed in Kotlin** this session;
+  (b) M3 baseline drifts ≤0.77px (halfLeading, a shared-engine omission on ALL platforms, sub-pixel).
+- **§1c FontMgr/ICU - the "empty FreeType stub" fear is DISPROVEN.** Native render of CJK
+  (你好世界 日本語 한국어) + **full-COLOR emoji** (😀🎉🚀❤) + control chars (nbsp/zwsp/en-dash) = zero
+  tofu. Color emoji + CJK fallback prove `FontMgr.default` is a real DirectWrite-backed system
+  manager, not an empty custom FreeType one. Remaining §1c work is doc-only (capture `args.gn`).
+
+Reference commands actually used (both probes print `metrics:` lines; native runs a real window):
+```bat
+demo\build\bin\mingwX64\debugExecutable\demo.exe --metricsprobe    :: native/fork metrics
+gradlew :demo:run --args="--metrics"                               :: JVM/upstream metrics
+set CDN_TEXT_METRICS=1 && ...demo.exe --screen=Buttons             :: raw per-paragraph dump
+```
+(The JVM leg's screenshot flag is `--screenshot-all=<dir>`, not the native `--screenshot=<file>`.)
+
+### Ordered Windows work (do top-to-bottom; full detail in the numbered sections below)
+
+1. **[§1a] Confirm the tab fix - ✅ DONE** (see session results above). Rendered a literal-tab
+   string on the fork; all `\t`→space, no tofu. The `SkiaParagraphEngine.shapedText` normalization
+   holds; no bypass path exists (2 `.addText(` sites, both `shapedText`).
+
+2. **[§1b] Confirm/resolve vertical metrics - ✅ RESOLVED (feared bug DISPROVEN).** Used the
+   `--metricsprobe` (native) vs `--metrics` (JVM) pair, NOT the screenshot diff (the JVM leg has no
+   `--screenshot=<file>`; it dumps the same `metrics:` table). Every paragraph HEIGHT matches JVM
+   exactly (leading applied identically) → correct-by-reference. Only a ≤0.77px M3-baseline drift
+   remains (halfLeading, all platforms). Separately fixed the fork's broken `LineMetrics.ascent/
+   descent` in Kotlin. Full data in §1b.
+
+3. **[§1c] Audit the fork FontMgr / gamma / ICU - ✅ AUDITED (fallback WORKS).** CJK + color emoji +
+   control chars all render with zero tofu on the fork → `FontMgr.default` is a real system
+   (DirectWrite) manager with working glyph fallback, NOT an empty FreeType stub. Remaining: capture
+   the fork's REAL `args.gn` (`SK_GAMMA_*`, ICU packaging, freetype-vs-dwrite) into the fork repo so
+   drift is auditable (doc-only, not a code blocker).
+
+4. **[§5] WIN-SMOKE gate** (pre-ship): (1) the §1b metrics dump, (2) tab/control-char render clean,
+   (3) the Windows-only `PrintWindow` probe (`scripts/probe/`), (4) `gradlew
+   :<module>:compileCommonMainKotlinMetadata` (only the Windows job compiles common metadata).
+
+5. **[§5] apiDump + publish FROM Windows** (host-specific; only the Windows job carries the full
+   mingwX64 variant table). Then, when Compose **1.12.0 stable** ships, do the re-pin + version
+   bump. Release runbook: [TOOLING.md](TOOLING.md).
+
+---
+
+## 1. Cross-platform FIDELITY (headline)
+
+All Windows divergences live **below Kotlin** - the mingw source set reuses
+`src/skikoRendererMain/kotlin` byte-for-byte (`compose/ui/ui/build.gradle.kts:102-113`),
+the only mingw-unique file is `PlatformGpu.mingw.kt` (13 lines, GPU only). So every
+divergence is in the **fork's Skia binary**, in **`FontMgr.default`'s per-OS impl**, or in
+the **GPU backend**. The fork is external (`bitsycore/skiko`,
+`com.bitsycore.skiko:skiko:0.150.1-mingw.1`) and its GN args are **not verifiable from this
+tree** - recovering them is a prerequisite for several fixes below.
+
+**Fidelity reference for Windows is skiko-on-JVM Compose Desktop on Windows** (also
+DirectWrite), NOT macOS/Linux. macOS↔Windows metric deltas partly exist in upstream
+Compose Desktop too (per-platform font backends). Reframe V-items as "match JVM-Windows"
+acceptance tests, not "bugs vs macOS".
+
+### 1a. Windows tab-character tofu - HIGH CONFIDENCE (root cause traced)
+
+Kotlin sets `ParagraphStyle.replaceTabCharacters = true`
+(`compose/ui/ui-text/src/skikoRendererMain/kotlin/.../renderer/skia/SkiaParagraphEngine.kt:234-236`,
+exact mirror of upstream `ParagraphBuilder.skiko.kt:625`, CMP-6589). Works on
+macOS/Linux (official skiko honors the flag → `U+0009` replaced by space before shaping).
+On Windows the same call runs against the fork's flat extern-C DLL, which evidently does
+**not** wire the setter → raw `\t` reaches HarfBuzz → NotoSans has no tab glyph → `.notdef`
+box. Font fallback is a **red herring**: no font has a tab glyph, only tab→space
+replacement cures it.
+
+- [x] **P0** Confirm - ✅ DONE (Windows 2026-08-04): rendered a literal-tab string on the fork
+      (`--screen=BasicText`); every `\t` shows a SPACE, no `.notdef`. The fork renders everything
+      else clean too, so tab→space was the only gap. Structural backstop: the module has exactly 2
+      `.addText(` sites, both `shapedText` - no raw tab can reach skiko.
+- [x] **P0** Fix (ship now, author project code): in
+      `.../SkiaParagraphEngine.kt`, feed skiko a normalized copy - added
+      `private val shapedText = if (text.indexOf('\t') >= 0) text.replace('\t', ' ') else text`,
+      used at `addText` (no-span path) and via `shapedText.substring(segStart, segEnd)`
+      (span path); `text` kept for ALL length/index queries (`getRectsForRange`,
+      `getCursorRect`, `wordBoundary`, `lineMetrics`, span cut-points). Length-preserving so
+      every offset consumer stays correct; this is exactly what Skia's flag does internally →
+      upstream-faithful; makes behavior platform-independent (no fork rebuild needed).
+      Kept `replaceTabCharacters = true` (harmless/redundant elsewhere).
+      **DONE** - compiles clean on macosArm64. Windows tofu render still needs on-device
+      confirmation (WIN-SMOKE §5).
+- [ ] **P2** Long-term true fix (fork, out of tree): wire
+      `ParagraphStyle::setReplaceTabCharacters` through the fork's extern-C surface,
+      rebuild/republish `skiko-windows-x64.dll`, bump `-PskikoMingwVersion`. Do this *in
+      addition to* the Kotlin fix, not instead - it keeps the port thin. Can't be verified
+      in-tree.
+
+### 1b. macOS-vs-Windows vertical text metrics - ✅ RESOLVED (Windows 2026-08-04): heights match JVM, feared bug DISPROVEN
+
+**WINDOWS RESULT (2026-08-04).** All targets render through the SAME Skia, so metrics are expected
+to be similar - and they are. Native `--metricsprobe` (fork) vs JVM `--metrics` (upstream skiko) on
+this host (NotoSans, density 1) print IDENTICAL paragraph heights and non-M3 baselines for every
+size 11→24 (`cell`/`one`/`three`/`oneM3`/`threeM3`, `base1`/`base3` all match). The fork does NOT
+drop lineHeight leading - the hypothesis below is disproven. Two small deltas remained, both
+handled in SHARED Kotlin (no fork rebuild, keeping fork-reliance minimal):
+
+  1. **Fork `LineMetrics.ascent/descent` mis-decode → FIXED in Kotlin (this session).**
+     `CDN_TEXT_METRICS` showed the fork's per-line `ascent`/`descent` constant (18.837/5.163)
+     regardless of `fontPx`, while `baseline`/`height`/`width` are correct (mac scales them:
+     37.674@30px). This is the fork's flat extern-C LineMetrics binding, NOT a Skia difference.
+     Lines stack contiguously so true ascent = `baseline - lineTop`; `SkiaParagraphOps.lineMetrics()`
+     now rebuilds ascent/descent from the reliable baseline+height when they're internally
+     inconsistent (guard `|ascent-(baseline-lineTop)|>0.5` = no-op on official skiko). Repairs caret
+     height / getLineTop/Bottom / vertical hit-test on Windows. **Behavioral caret check → WIN-SMOKE.**
+  2. **M3 baseline drift ≤0.77px (halfLeading) - SHARED-engine omission, all platforms.** `base1M3`
+     differs native-vs-JVM by ≤0.77px in the 11→24 sweep (size 14 → 0.28px, sub-pixel), 2.19px in
+     the contrived `boundary 24/25` case. Root cause is NOT the fork: `SkiaParagraphEngine` maps
+     `LineHeightStyle.trim`→HeightMode but never wires `halfLeading`/`LineHeightStyle.Alignment`, so
+     macOS-native drifts from JVM by the same amount (parity tolerated it as sub-pixel). Fixable in
+     shared Kotlin (`textStyle.halfLeading` from the alignment); deferred pending a cross-platform
+     parity re-check (can't run mac parity from a Windows host).
+
+Native-fork metricsprobe vs JVM `--metrics` (this host) - identical except `base?M3`:
+```
+size=14 lh=20 cell=19 one=19 three=59 base1=14.898 base3=54.898 oneM3=20 threeM3=60 base1M3: 15.682 fork / 15.398 jvm
+size=24 lh=30 cell=33 one=33 three=93 base1=25.968 base3=85.968 oneM3=30 threeM3=90 base1M3: 23.546 fork / 24.312 jvm
+boundary 24/25 m3=25  base: 19.622 fork / 21.812 jvm
+```
+
+The vertical-layout code path is **identical** on all targets. The lineHeight/HeightMode
+path is a byte-faithful port of upstream and is NOT the cause: m3 `labelLarge` has
+lineHeight 20sp > fontSize 14sp with `LineHeightStyle.Default.trim == Both` →
+`HeightMode.DISABLE_ALL`, which collapses the single-line box to `fontAscent + fontDescent`
+of the font itself (`SkiaParagraphEngine.kt:244-249`, matches upstream
+`ParagraphBuilder.skiko.kt:631-646`). So box height is driven entirely by the font's
+reported ascent/descent.
+
+Root cause: **`FontMgr.default` resolves to a different Skia font scaler per build** for
+the *same* `font/NotoSans.ttf` bytes (`SkiaFonts.kt:38,44,50`) - CoreText on macOS,
+fontconfig/FreeType on Linux, DirectWrite (or FreeType, unverified) in the fork on Windows.
+Different backends select different metric tables (hhea `ascender/descender` vs OS/2
+`sTypoAscender/Descender` vs `usWinAscent/Descent`) and honor the OS/2 `USE_TYPO_METRICS`
+fs_selection bit differently. NotoSans is the textbook case (large top-heavy ascent).
+`SkiaParagraphEngine.kt:147-148` read `-defaultFont.metrics.ascent`/`.descent`;
+`:150-169 lineMetrics()` forwards skiko's numbers verbatim; `SkiaParagraph.native.kt:116,148-153`
+consume them. Contributors V2 (hinting Normal on Windows grid-fits vertically, CoreText
+ignores it) and V3 (subpixel/edging) are secondary and per-scaler.
+
+**Hypothesis, not confirmed:** whether Windows-native actually *diverges from
+Windows-JVM*. If it matches JVM-Windows it's correct-by-reference (not a bug), and the
+macOS↔Windows delta is expected upstream behavior.
+
+- [x] **P0** Confirm FIRST - ✅ RESOLVED (Windows 2026-08-04; heights == JVM, see WINDOWS RESULT
+      above). Diagnostic **LANDED**: `SkiaParagraphEngine.kt` dumps
+      `defaultFont.metrics.{ascent,descent,leading}`, `paragraph.height`,
+      `lineMetrics[0].{ascent,descent,baseline,height}`, `familyName` + `fontPx` per built
+      paragraph when `CDN_TEXT_METRICS=1` (mirrors the `CDN_PROFILE` env-flag convention).
+      Run `CDN_TEXT_METRICS=1 <app> --screen=Buttons` (native) and the JVM parity app on the
+      SAME host, diff the lines. macOS baseline captured (see below). **REMAINING (Windows
+      host):** compare Windows-native vs **skiko-JVM-Windows**. Expectation: `fontPx` +
+      lineHeight + heightMode identical, `metrics.ascent` differs by scaler.
+      **Acceptance test:** Windows-native == skiko-JVM-Windows (→ correct-by-reference, not a
+      bug); if they differ, it's a fork scaler fix (next item).
+
+      **macOS baseline captured (`--screen=Buttons`, DPR 2):** for the fontPx=30 button
+      labels ("Filled Button" / "OutlinedButton" / "TextButton"): font metrics
+      `ascent=-32.07 descent=8.79 leading=0` (font box = **40.86px**), but the line box is
+      `line0[ascent=37.67 descent=10.33 height=48.0]`, `paraHeight=48`. So macOS DOES apply
+      the lineHeight leading (48 > 40.86) and distributes it **asymmetrically - ~5.6px above,
+      ~1.5px below** → exactly the "extra space on top of the text" the report describes.
+      **SHARPENED HYPOTHESIS:** this is NOT a mac bug - it's correct lineHeight distribution.
+      The likely Windows story is the MIRROR of §1a: the fork's flat extern-C surface doesn't
+      wire the `ParagraphStyle` height/strut path, so Windows renders **tight to the font box
+      (~41px, no leading)** = the "fitted to text" look. **Sharpened WIN-SMOKE check:** for the
+      SAME label, compare `paraHeight` + `line0.height`. If macOS/JVM = 48 but Windows-native
+      ≈ 41, the fork drops lineHeight leading (fork fix: wire `heightMode`/strut, like
+      `replaceTabCharacters`); a Kotlin fallback is a manual `StrutStyle`. If Windows-native
+      == Windows-JVM, it's correct-by-reference.
+
+      **macOS baseline raw lines** (`CDN_TEXT_METRICS=1 demo --screen=Buttons`, DPR 2) - diff
+      Windows-native + Windows-JVM against these; the fontPx=30 rows are the cleanest signal:
+      ```
+      text='Filled Button'  fontPx=30.0  ascent=-32.070007 descent=8.789978 leading=0.0  paraHeight=48.0  line0[ascent=37.674 descent=10.326 baseline=37.674 height=48.0]
+      text='OutlinedButton' fontPx=30.0  ascent=-32.070007 descent=8.789978 leading=0.0  paraHeight=48.0  line0[ascent=37.674 descent=10.326 baseline=37.674 height=48.0]
+      text='TextButton'     fontPx=30.0  ascent=-32.070007 descent=8.789978 leading=0.0  paraHeight=48.0  line0[ascent=37.674 descent=10.326 baseline=37.674 height=48.0]
+      text='Outlined'       fontPx=28.0  ascent=-29.932007 descent=8.203980 leading=0.0  paraHeight=40.0  line0[ascent=31.395 descent=8.605  baseline=31.364 height=40.0]
+      ```
+      (family='Noto Sans' on all.) Expectation if correct: `fontPx`, `paraHeight`, `line0.height`
+      match JVM-Windows exactly; the raw `ascent`/`descent` may differ from these macOS numbers
+      because the Windows scaler is FreeType (§1c), but the LINE BOX must still match JVM-Windows.
+- [x] **P1** ~~If Windows-native != Windows-JVM: fix in the fork~~ - **N/A (2026-08-04):** heights
+      MATCH JVM-Windows exactly, so no fork scaler/FontMgr change is needed for vertical metrics.
+      The `makeFromData` typefaces already get the same metric-table selection as skiko-JVM-Windows.
+      The one residual (M3 halfLeading) is a shared-Kotlin fix, not a fork one.
+- [ ] **P2** (Optional, STRONGER than upstream) If cross-platform pixel-identity is
+      wanted over matching each host's stock Compose Desktop: build a single
+      FreeType/`SkFontMgr_Custom_Empty`-backed `SkFontMgr` used on ALL native targets for
+      the bundled fonts, so NotoSans yields identical ascent/descent everywhere.
+      Intentional departure from per-platform upstream behavior - decide deliberately.
+- [ ] **DO NOT** "fix" by injecting a default `LineHeightStyle` or clamping ascent in
+      `SkiaParagraphEngine.kt` - that desyncs from upstream `DISABLE_ALL` and masks, not
+      resolves, the metric divergence.
+
+### 1c. Other fork-vs-official divergences
+
+- [x] **P1** ~~`FontMgr.default` may be an empty/stub manager on the fork~~ - **DISPROVEN
+      (Windows 2026-08-04).** Native render of CJK (你好世界 日本語 한국어) + **full-COLOR emoji**
+      (😀🎉🚀❤) + control chars = zero tofu. Color emoji + CJK fallback are impossible with an empty
+      custom FreeType manager, so the fork's `FontMgr.default` IS a real DirectWrite-backed system
+      manager with working glyph enumeration/fallback. No fork change needed. `SkiaFonts.kt` wiring
+      stays as-is.
+- [x] **P1** `FontMgrWithFallback` - ANALYZED + fallback now VERIFIED on Windows. The port
+      does `setDefaultFontManager(fontMgr)` [system] + `setAssetFontManager(provider)`
+      [bundled] (`SkiaFonts.kt:49-52`). This is **functionally equivalent** for missing-glyph
+      fallback on macOS/Linux/Windows-JVM: skiko's shaper tries the asset provider (bundled
+      Noto + aliases) first, then the default/system manager for CJK/emoji fallback, which
+      resolves because the system FontMgr has those fonts. Rewriting to
+      `setDefaultFontManager(FontMgrWithFallback(provider))` risks a macOS fallback
+      regression with no observable gain, and I can't visually verify CJK/emoji fallback on
+      this host. **The real gap was thought to be Windows-fork-only** (fork `FontMgr.default`
+      empty stub → no system fallback) - but that's **DISPROVEN (2026-08-04):** CJK + color-emoji
+      fallback works on native Windows too (item above). So the setDefault/setAsset wiring is fine
+      on ALL targets. **Decision:** leave the Kotlin as-is; nothing to fix in the fork here. Re-open
+      only if a CJK/emoji fallback bug is actually observed.
+- [x] **P2** ~~ICU/unicode data packaged differently in the fork~~ - **VERIFIED OK (2026-08-04).**
+      Rendered U+00A0 (nbsp → visible space), U+200B (zwsp → zero-width/collapsed), en-dash, and
+      U+0009 (tab, pre-replacement) on native Windows: all classified/handled correctly, no tofu.
+      The force-exported `uloc_*_skiko` symbols do their job; skunicode classification works. (This
+      is also why HarfBuzz shaping + skparagraph bidi work at all - ICU data is present via
+      icudtl.dat.)
+- [~] **P2** Text gamma/AA edges: a Skia **build-time constant**
+      (`SK_GAMMA_EXPONENT`/`SK_GAMMA_CONTRAST`/`SK_GAMMA_APPLY_TO_A8`), NOT a GL-vs-Metal
+      runtime difference. **Note (2026-08-04):** native Windows text AA looked clean in the render
+      (no visible AA anomaly), so no fork gamma fix is pursued for 1.0. Still worth capturing the
+      fork's values in the fork repo (see the args.gn item below). **Kotlin-side rasterization
+      settled:** the `RASTER_EDGING/HINTING/SUBPIXEL` in `SkiaParagraphEngine` come from
+      `FontRasterizationSettings.PlatformDefault`, which was verified (2026-08-04) to reproduce
+      upstream Compose Desktop's per-OS defaults VERBATIM (Win/mac=Normal hinting, Linux=Slight).
+      **User decision:** keep the upstream-faithful per-OS behavior (match each platform's stock
+      CMP), NOT a forced uniform cross-platform look. So there is no SDL_TTF-era gamma hack left to
+      strip - Skia is configured exactly as upstream does it.
+- [x] **GL-vs-Metal AA/gamma/color-space - RULED OUT as a primary cause.** Both bridges
+      create the surface `colorSpace = null` (`SkiaGLBridge.kt:68-74`,
+      `SkiaMetalBridge.kt:133-139`) - identical un-color-managed legacy blending. Only
+      deltas are cosmetic-correct: `RGBA_8888`/`BOTTOM_LEFT` (GL) vs `BGRA_8888`/`TOP_LEFT`
+      (Metal) - channel order + Y-flip, matched to buffers. Windows uses OpenGL
+      (`PlatformGpu.kt:20`), same backend as Linux, so GL-vs-Metal can't explain a
+      Windows-vs-Linux gap at all. Deprioritized - no action.
+- [~] **P1** The fork's Skia build config (GN args). **Lead extracted from git history**
+      (the old `SKIKO-MINGW-FEASIBILITY.md`, deleted as stale - its build recipe lives in
+      `git show bdb5c64d^:SKIKO-MINGW-FEASIBILITY.md`): the fork's Route-1a recipe builds Skia
+      with **`skia_use_freetype`**, i.e. the Windows text scaler is **FreeType**, not
+      DirectWrite and not macOS CoreText - a concrete reason the SAME NotoSans bytes yield
+      different ascent/descent on Windows (different metric-table selection) AND why fork
+      `FontMgr.default` may not enumerate Windows system fonts for glyph fallback (FreeType
+      has no system fontmgr without fontconfig). **CAVEAT:** that's the *recommended recipe*,
+      not a verified dump of the shipped `0.150.1-mingw.1` GN args. **REMAINING:** whoever
+      rebuilds the fork should capture the real `args.gn` (`SK_GAMMA_*`, ICU packaging,
+      freetype-vs-dwrite) alongside the fork sources so drift is auditable - NOT as a doc in
+      this repo (kept lean); a comment in the fork repo or `build-sdl.properties`-style pin.
+
+---
+
+## 2. VENDORING & upstream-fidelity debt
+
+Vendor hygiene is **release-ready**: `check-vendor-drift.py` reports all 10 manual vendors
+match pin `v1.12.0-beta03+dev4483`; zero commonMain rule-1 violations (the 3 authored
+`androidx.compose.*` files in commonMain are all provenance-tracked Rule-3 vendors). The
+macosMain DIAGNOSTIC GAP families (`ui/ui` 12, `foundation` 23: `CoreTextField.macos.kt`,
+`SelectionManager.macos.kt`, `PlatformClipboard.macos.kt`, …) are **correctly excluded**
+(AppKit/NSView; the port uses SDL) - keep them in gaps. **Do not spend 1.0.0 effort
+re-vendoring.** The debt is **completing native-actual stubs**.
+
+### P0 - blocks fidelity/correctness
+
+- [~] **P0** Text context menu (right-click copy/paste/select-all) - **RECONCILED: already
+      works, no reimplementation.** Static trace confirmed the menu is wired end-to-end
+      through the vendored LEGACY path: text-level `ContextMenuArea` (`ContextMenu.native.kt`)
+      → `CommonContextMenuArea` (`vendor/common/.../text/CommonContextMenuArea.kt`) → (native
+      `ComposeFoundationFlags.isNewContextMenuEnabled = false`, so the legacy branch) →
+      `contextmenu.ContextMenuArea` → `contextMenuGestures`/`onRightClickDown`
+      (`isSecondaryPressed`) → `ContextMenuPopup` → `Popup.native.kt` (hosted by
+      `LocalPopupHost` at the app root). Items are real: `TextFieldSelectionManager` /
+      `SelectionManager.contextMenuBuilder` emit Cut/Copy/Paste/SelectAll with real actions.
+      SDL right-click → `PointerButton.Secondary` (`SDL3EventMapper.kt`) →
+      `isSecondaryPressed` (`PointerEventBridge`). The three "NOP" seams belong to the
+      DISABLED *new* context-menu API and are unreachable - **DONE:** their misleading
+      `TODO(CMP-7819)` comments corrected to say so, in all three files.
+      **REMAINING:** an interactive right-click smoke check (no headless driver here - fold
+      into manual/WIN-SMOKE). Known limitation, not a breakage: Paste enablement is
+      plain-text-only (`ClipboardPasteState.hasClip = hasText`, see P2 below).
+- [ ] **P1** DatePicker/TimePicker localization - VERIFIED current state:
+      `material3/.../internal/PlatformDateFormat.native.kt` is a real kotlinx-datetime
+      formatter that DOES honor CLDR patterns/skeletons (renders "Jul 29, 2026" /
+      "July 2026" correctly - the agent's "always yyyy-MM-dd" finding was stale). Genuine
+      remaining gaps, all narrower than a correctness blocker: field NAMES English-only
+      (`:29 weekdayNames`, `:147-154 MONTH_NAMES/ABBR` - no CLDR data bundled), `:27
+      firstDayOfWeek=1` fixed Sunday, `:67 is24HourFormat()=true` fixed, `:46 parse()`
+      ISO-8601-only. Upstream `darwinMain` uses `NSDateFormatter` (not portable). **Fix
+      (author):** bundle a CLDR subset or K/N i18n lib for localized names + locale-aware
+      first-day/24h; also unblocks `CalendarLocale.native.kt:20` (fixed `"en"`). Ships
+      readable English dates today - polish, not a P0 gate.
+- [x] **P0** Float pointer coordinates - `SDL3EventMapper.kt` `.toInt()`-truncated SDL's
+      Float `mb.x`/`mb.y`/`mm.x`/`mm.y` and the wheel `mouse_x/y` before the DPR multiply in
+      `ComposeWindow.kt`. On 2× displays a click at logical 100.9 → physical 200 not ~201,
+      quantizing the caret to 2px steps near glyph edges. **DONE:** widened
+      `LegacyPointerEvent.x/y` and `AppEvent.MouseWheel.x/y` to `Float`, dropped the
+      `.toInt()` at the three mapper construction sites, and removed the now-redundant
+      `.toFloat()` at the two `ComposeWindow` read sites. Consumers fully contained (verified
+      by grep). Builds + runs clean on macosArm64.
+
+### P1 - quality / parity
+
+- [ ] **P1** RTL text unsupported - `ui-text/.../SkiaParagraph.native.kt:112`
+      `textDirection = ResolvedTextDirection.Ltr` fixed field; `getParagraphDirection()`
+      (`:202`) always Ltr. Bidi run direction (`:204`) does read box direction (partial
+      machinery). Root cause: `text/intl/Locale.native.kt isRtl()` unimplemented. Fix
+      (author) tied to P1.2 engine.
+- [ ] **P1** `PlatformFontLoader` NOP - `ui-text/.../font/FontFamilyResolver.native.kt`
+      `SdlPlatformFontLoader.loadBlocking`/`awaitLoad` NOP;
+      `PlatformFontFamilyTypefaceAdapter.resolve` returns `Immutable(Unit)`. Raw androidx
+      `Font(bytes)`/`ResourceFont` don't load (compose-resources `Font()` works). Upstream
+      `SkiaFontLoader.skiko.kt` is the vendorable reference. This is the long-deferred P3.2
+      font resolver - **high-risk L**, parity harness wouldn't exercise it. Scope
+      deliberately for 1.0.0 (accept-and-document vs attempt). **NOW ALSO GATES §6** - the
+      2026-08-04 spike found the verbatim engine-vendor routes font resolution through this NOP, so
+      implementing this loader (so `SkiaFonts`' icon/variable-axis model rides upstream's seam) and
+      the §6 engine-vendor are ONE effort. Do them together, with macOS/Linux verification.
+- [ ] **P1** `CharHelpers.skiko.kt` grapheme-break logic - the ONE cheap selective-vendor
+      win from the hand-rolled text engine. Fixes `findPrecedingBreak`/`findFollowingBreak`
+      splitting emoji/combining marks in `StringHelpers.native.kt:31` +
+      `CharHelpers.native.kt:14`. (Giving `:foundation` a `skikoRenderer` source set would
+      unblock this + `DragAndDropSource.skiko` - L-effort structural move, per §13a.)
+- [~] **P1** `Serif`/`Cursive` generic families - RE-SCOPED after reading `SkiaFonts.kt`.
+      They do NOT silently collapse to sans: `baseTypeface()` routes `generic:serif` /
+      `generic:cursive` through `resolveGeneric()` → `fontMgr.matchFamilyStyle()` over a
+      per-OS candidate list (`genericFamilyAliases`: Times/Noto Serif/… on each host), only
+      falling back to the bundled default if NONE is installed. So serif/cursive already
+      render as a real serif/cursive wherever the OS ships one (all three target OSes do).
+      The only true gap is **cross-platform pixel-identity** / a host with no serif installed,
+      which needs a BUNDLED Noto Serif - an app-level opt-in (buildSrc `downloadNotoFonts` +
+      data.kres size cost), not a library correctness bug. **Decision:** leave library
+      resolution as-is; offer bundled-serif as an opt-in later if an app needs it.
+- [x] **P1** Document the hand-rolled text engine as an **accepted architectural
+      deviation** - **DONE:** rationale header added to the top of
+      `ui-text/compose-fork.txt` (the exact place someone would go to "fill" the gaps),
+      explaining the reduced local engine, the flat-source-set reason, and that RTL /
+      stroke-DrawStyle / grapheme reductions are tracked here (§2), not fixed by vendoring.
+      Also reflected in `SkiaParagraphEngine.kt`'s header and CLAUDE.md's renderer summary.
+
+### P1/P2 - reduced-coverage + accessibility
+
+- [ ] **P1** Text paint path handles only `SolidColor`
+      (`SkiaParagraph.native.kt:253-256`) - no brush/gradient text fill, `drawStyle`
+      (stroke), or non-`SrcOver` blendMode. Part of the reduced style coverage; extend on
+      the local engine.
+- [ ] **P1** `SkiaParagraphEngine.kt:150-164` span segmentation drops partial `SpanStyle`
+      overlaps (keeps only fully-covering `start<=segStart && end>=segEnd`). Documented
+      divergence (`b63-upstream-text-mingw.md`) - widen to true interval segmentation.
+- [~] **P1** Accessibility absent - `ComposeOwner.kt:~340` builds a `semanticsOwner` never
+      traversed to any OS a11y API; `SemanticsRegion.native.kt intersect()/difference()`
+      hardcode `false`. Not vendorable (NSAccessibility/UIA/AT-SPI). **Decision for 1.0.0:
+      out of scope for desktop.** The full a11y pipeline stays P2/out.
+      - [x] **P0** No-op `PlatformScreenReader` - `CompositionLocals.native.kt`
+        `LocalPlatformScreenReader` default no longer throws (`error(...)`); it returns an
+        `InactivePlatformScreenReader` (`isActive = false`) so a11y-gated vendored code
+        degrades to "no reader present" instead of crashing. **DONE** - builds + runs clean.
+- [ ] **P2** `SkiaFonts.kt` fidelity: `resolveCache` unbounded (font-cache half of P3.4
+      deferred); variation key passes `null` density (`:65,78`) so density-dependent `opsz`
+      in sp resolves wrong. `NamedFont.equals/hashCode` axis identity reportedly fixed -
+      re-verify.
+
+### P2 - cosmetic / edge
+
+- [ ] **P2** `BlendMode.Multiply` renders wrong - opaque cyan×yellow reads back blue;
+      likely Metal premultiply in graphics-layer flatten, not the `toSkia()` map. Isolate on
+      the Skia draw path.
+- [ ] **P2** Drag-OUT of window NOP - `ui/.../draganddrop/Sdl3DragAndDropOwner.kt:39`
+      `requestDragAndDropTransfer`; `DragAndDropSource.native.kt:36` no drag-shadow. SDL3
+      has no portable start-drag → needs NSDraggingSession/DoDragDrop/XDND per-OS.
+      Drop-INTO works. Accepted 1.0 gap (SDL platform limit) - document.
+- [ ] **P2** `NativeStringDelegate.native.kt:17` `toUpper/toLowerCase` ignore `locale`
+      (Turkish i). Upstream `darwin` unvendorable (NSString).
+- [ ] **P2** Prefetch scheduler NOP - `platform/PrefetchLocals.native.kt:18`, lazy lists
+      skip ahead-of-time composition (scroll-in jank).
+- [ ] **P2** `ClipboardPasteState.hasClip` aliased to `hasText`
+      (`TextFieldSelectionState.native.kt:43`) - image-only clipboard undetected.
+- [ ] **P2** `ComposeOwner.kt` gaps: `autofill`/`autofillManager` null (`:324`),
+      `hapticFeedBack` NOP (`:279`), deprecated `clipboardManager` NOP (`:287`, real
+      `LocalClipboard` works), `textToolbar` stub (`:311`, touch-gated). No multi-monitor
+      enumeration (`SDL_GetDisplays` unused). Most match upstream desktop - verify, then
+      leave or fill.
+- [x] **P2** `installGlobals()` → `registerGenericFonts()`: VERIFIED not a hot-path cost -
+      `registerGenericFonts()` already early-returns on a `fRegistered` flag
+      (`GenericFonts.kt:20-26`), so the per-event call is a single boolean check, not a
+      re-register. Original premise inaccurate; no change needed. (Minor residue: the
+      `ImeBridge.onSessionActiveChange` lambda is reassigned per event - negligible, left
+      as-is since it repoints per active window.)
+
+---
+
+## 3. SDL slimming
+
+Static lib built from source per host (`scripts/build-sdl/build-all.py`, ref
+`release-3.4.12`); linked into the exe via `sdl3.def` (`staticLibraries=libSDL3.a`). Today
+only tests/examples + Windows D3D12/GPU are off (`build-all.py:311-319`). `SDL_Init` uses
+**`SDL_INIT_VIDEO` only** (`SDL3Backend.kt:49`).
+
+**USED (keep ON):** Video/window, Events, Clipboard, Dialog (file open/save - no cheaper
+substitute; Linux uses portal/zenity, keep deps), OpenGL + Metal contexts, Render (2D CPU-
+raster blit path: `SkiaSurfaceBridge` uploads to `SDL_Texture` + `SDL_RenderPresent`),
+Filesystem, Cursor, Locale, System theme, Text input/IME, OpenURL, timing/hints.
+
+**UNUSED (disable - zero references, no transitive need):** Audio, Joystick (→disables
+Gamepad), Haptic, HIDAPI, Sensor, Power, Camera, GPU API, Offscreen video driver, virtual
+joystick.
+
+- [x] **P1** Added to `build-all.py` shared `vExtra`: `-DSDL_AUDIO=OFF`,
+      `-DSDL_JOYSTICK=OFF`, `-DSDL_HAPTIC=OFF`, `-DSDL_HIDAPI=OFF`, `-DSDL_SENSOR=OFF`,
+      `-DSDL_POWER=OFF`, `-DSDL_CAMERA=OFF`, `-DSDL_GPU=OFF`, `-DSDL_OFFSCREEN=OFF`,
+      `-DSDL_VIRTUAL_JOYSTICK=OFF`. Promoted `-DSDL_GPU=OFF` from the Windows-only branch to
+      the shared list; kept the per-host `-DSDL_RENDER_D3D12=OFF` (Windows). (Skipped
+      `-DSDL_DISABLE_INSTALL_DOCS` - not a real SDL3 option; the build's `cmake --install`
+      is relied upon.) All ten confirmed zero-reference by grep before disabling.
+- [~] **P1** After the flag change, rebuild + run apps to confirm no regression.
+      **DONE on macOS/Metal:** `build-all.py` rebuilt libSDL3.a clean with the new flags;
+      `:demo` links + runs to a settled screenshot (TextField screen, no visual regression);
+      `:apidemo` links clean too. **PENDING:** both apps on Linux + Windows hosts (fold into
+      WIN-SMOKE §5). If audio/gamepad is ever needed by a consumer app, re-enable the flag
+      and rebuild the static lib (build-time only).
+- [x] **P2** Prune now-unreferenced macOS frameworks from `sdl3.def`. **DONE:** verified
+      against the regenerated `libs/SDL3/lib/pkgconfig/sdl3.pc` `Libs:` line (source of
+      truth), which after slimming no longer references `CoreAudio`, `AudioToolbox`,
+      `AVFoundation`, `GameController`, `ForceFeedback`, or weak `CoreHaptics` - removed all
+      six from `linkerOpts.osx` (kept `CoreMedia`, which the `.pc` still lists). Demo relinks
+      clean. (Left Linux `linkerOpts` alone - those `-l` entries serve Skia/GL/X11, not the
+      disabled SDL subsystems.)
+- [ ] **P2** (higher-risk, flag-don't-apply) Render-driver pruning to software-only. Only
+      the CPU-raster fallback uses `SDL_Render`; GL/Metal go direct. But
+      `SDL_CreateRenderer(window, null)` (`SDL3Backend.kt:117`) lets SDL pick the first
+      driver - with only software present it picks software (fine) but couples the fallback
+      to that assumption. **Conservative: leave render drivers alone.**
+
+**Do NOT** add `-DSDL_DISABLE_INSTALL` - the build relies on `cmake --install`
+(`build-all.py:342`) to stage `libSDL3.a` + headers. `SDL_DYNAMIC_API` auto-disables for
+static builds (no flag needed). **Risk:** a future consumer app needing SDL audio/gamepad
+requires a static-lib rebuild (build-time, not a code change).
+
+---
+
+## 4. Performance
+
+Prior PLAN Phases 0–3 landed; §12 measurement showed **no steady-state perf gap on
+macOS/Metal**. Remaining perf question (if any) is Windows-GL or heavy-interaction
+specific. Retained-layer engine is byte-for-byte upstream - not the gap.
+
+- [ ] **P2** WON'T-FIX confirmed, keep as-is (don't relitigate): P0.4 per-frame full-surface
+      clear + P0.6 per-frame Metal drawable reacquire (`CAMetalDrawable` single-use per
+      frame, matches upstream `MetalRedrawer`).
+- [ ] **P2** P2.2 upstream `GlobalSnapshotManager` invalidation-driven scheduling -
+      deferred; coalescing half done by P1.3; full manager is skiko-windowing-coupled
+      (an explicit renderer non-goal - skiko-windowing-coupled). Leave deferred unless a
+      Windows-GL perf gap surfaces.
+- [ ] **P2** `SkiaImageCache` font-cache half of P3.4 - evicted typefaces stay referenced by
+      live paragraphs + `TypefaceFontProvider` (no clean unregister) so eviction frees no
+      memory. Native-resource lifecycle backstop is the periodic `GC.collect()` nudge (top-
+      level `Paragraph` a live `Text` holds has no Compose dispose seam). Accept for 1.0 or
+      add a provider-unregister path.
+- [ ] **P2** P4.1 second-renderer manual-vendor reversal (restore upstream RenderNode
+      shadows via `SkiaGraphicsContext.setLightingInfo` + relocate
+      `prepareTransformationMatrix`; deltas D2–D6). Buys vendoring cleanliness at
+      shadow-lighting/hit-test regression risk (current `NativeShadowCanvas` shadows render,
+      draw=0.08ms). Low ROI - deferred, needs full verify-mac + parity.
+- [ ] **P2** Profile the shipped **Windows-GL** binary (`CDN_PROFILE=1`) under heavy
+      interaction before ship (present phase is vsync-capped by display refresh - profile on
+      the target monitor). Only open perf unknown.
+
+---
+
+## 5. API coverage / release mechanics
+
+API coverage vs upstream is **99%** (8665/8751 decls via `compose-coverage.py`). Misses are
+AppKit/UIKit/web host actuals (N/A), `ImageComposeScene`/`renderComposeScene` (test util),
+and the `ui-text.platform` font layer (= P3.2 font resolver). The 1076 "extra" decls are
+umbrella-repo modules the tool can't compare + version skew, not invented surface.
+
+- [ ] **P0** Re-pin refs to Compose **1.12.0 stable** when it ships (currently
+      `v1.12.0-beta03+dev4483` - no clean beta03 tag on Maven). Bump both
+      `scripts/compose-fork/compose.properties` refs, re-sync (`scripts/compose-fork/sync.sh`),
+      let the build surface breakage.
+- [ ] **P0** Bump `vComposeJvmVersion` in `:demo` / `:apidemo` / `:material-symbols` (JVM
+      parity leg currently forced to beta02 by documented skew - native leads).
+- [ ] **P1** Run `check-vendor-drift.py` after the ref bump - re-stamp `VENDOR-BASE` on the
+      10 manual vendors, hand-reconcile any that actually changed base..pin.
+- [~] **P0** WIN-SMOKE fidelity pass (Windows host only, pre-ship gate): the Mac runbook
+      cannot cover the shipped mingwX64 binary. Assert: (1) NotoSans `FontMetrics` dump
+      native-vs-JVM-Windows (§1b acceptance) - **✅ DONE 2026-08-04 (`--metricsprobe`==`--metrics`)**;
+      (2) `\t`/control-char render clean (§1a) - **✅ DONE**; (3) the Windows-only `PrintWindow`
+      probe - pending (interactive); (4) the common-metadata publish job - compile gate now
+      **✅ GREEN (2026-08-04, see the fix below)**; the actual publish + downstream-consume smoke
+      still owed. Remaining: (3) `PrintWindow` probe + the interactive caret-height check for the
+      §1b LineMetrics fix.
+- [ ] **P0** apiDump is **host-specific** - do NOT commit macOS dumps. Only the **Windows
+      publish job compiles common metadata** (owns the root KotlinMultiplatform publications
+      - the only host declaring every target, so only its `.module` files carry the full
+      variant table; macOS-published roots left v0.1.15 without mingwX64 variants). Test
+      `gradlew :<module>:compileCommonMainKotlinMetadata` before tagging; publish from
+      Windows.
+- [x] **P0** **FIXED (2026-08-04) - common-metadata compile is now GREEN** (`compileCommonMainKotlin
+      Metadata` across all modules → BUILD SUCCESSFUL). Was RED, blocking the Windows publish.
+      Running `:material3:compileCommonMainKotlinMetadata` (or the aggregate) had failed at
+      `:foundation:compileNativeMainKotlinMetadata` (pulled in via `:foundation:allMetadataJar`):
+      `Scrollbar.skiko.kt` + `v2/Scrollbar.skiko.kt` - `Declaration annotated with
+      '@OptionalExpectation' can only be used in common module sources`
+      (`OPTIONAL_DECLARATION_USAGE_IN_NON_COMMON_SOURCE`). **Root cause:** upstream keeps these
+      `.skiko.kt` files in `skikoMain`, which INCLUDES the JVM-desktop target, so `@JvmName`/
+      `@JvmStatic`/`@file:JvmName` resolve; the port vendors them into **native-only `nativeMain`**
+      (no JVM target under it), so those JVM annotations are orphaned and the *metadata* compile
+      rejects them (per-target compile tolerates them - that's why the APPS build fine, but the
+      publish's `allMetadataJar` recompiles nativeMain metadata and dies). `:ui` and below pass;
+      `:foundation` is the first break. **Blast radius:** 14 vendored native files use `@Jvm*`
+      (`grep -rE "@file:JvmName|@JvmName|@JvmStatic" .../src/vendor/native .../src/nativeMain`); 11
+      are in the GITIGNORED, sync-regenerated `src/vendor/native/` tree, so per-file edits DON'T
+      survive a re-sync. **Fix (build/sync-level, not per-file):** either (a) a `sync.sh`
+      post-step that injects `@file:Suppress("OPTIONAL_DECLARATION_USAGE_IN_NON_COMMON_SOURCE")`
+      (or strips `@Jvm*`, which are no-ops with no JVM library target) into vendored native files -
+      there's precedent: `components-resources/…/ResourceState.blocking.kt` already carries that
+      suppress; or (b) a KGP-level relaxation of the native metadata compilation. Needs a real
+      publish + downstream-consume verification after. Dedicated effort - likely THE reason the
+      Windows metadata publish never went green.
+      **FIX APPLIED (2026-08-04):** the root turned out narrower - sync.py ALREADY injects the K2
+      `@file:Suppress("OPTIONAL_DECLARATION_USAGE_IN_NON_COMMON_SOURCE", "LESS_VISIBLE_TYPE_ACCESS_IN_INLINE")`
+      into every `src/vendor/` .kt (`sync.py:313`), so the regenerated tree was fine. The only gap
+      was the two COMMITTED manual vendors in `src/nativeMain` that sync doesn't regenerate:
+      `foundation/…/Scrollbar.skiko.kt` + `v2/Scrollbar.skiko.kt`. Added the identical `@file:Suppress`
+      to both (provenance comment updated; `check-vendor-drift` still clean). Full
+      `compileCommonMainKotlinMetadata` now green. **Remaining before publish:** run the actual
+      publish + a downstream-consume smoke (the compile gate is necessary, not proof the `.module`
+      variant table is complete).
+- [ ] **P1** Version bump to `1.0.0` across published coords once the above are green.
+- [x] **P0** Doc-hygiene blocker: `CLAUDE.md` documentation map referenced `RENDERER.md`,
+      `SKIKO-MINGW-FEASIBILITY.md`, and `TODO.md`. **DONE:** removed `RENDERER.md` +
+      `SKIKO-MINGW-FEASIBILITY.md` (stale/historical - current renderer essentials inlined in
+      CLAUDE.md's doc map, the rest recoverable from git history); fixed the `CLAUDE.md`
+      line-1 `ean` typo; dropped the `TODO.md` link (never committed) → its content is PLAN.md
+      §2. `git grep` confirms no remaining links to any deleted doc.

+
+## 6. Vendor the upstream skiko text engine (next major refactor - approved 2026-08-04)
+
+**Goal:** honour "VENDOR ALL WE CAN". Delete the hand-rolled reduced text engine
+(`SkiaParagraph.native.kt` + `NativeParagraphOps` seam + `SkiaParagraphEngine.kt` +
+`FontRasterizationSettings.native.kt` port) and vendor upstream's skiko text subsystem VERBATIM.
+
+**Why it was hand-rolled (the REAL reason, not SDL_TTF):** `Paragraph` is `expect sealed interface`
+(`vendor/common/…/Paragraph.kt:56`) whose `actual` sits in the **skiko-FREE `nativeMain`**, so a
+sealed implementer can't touch skiko → the hand seam. `nativeMain` is skiko-free because it's the
+shared parent of the **official-skiko** (mac/linux, `libs.skiko`) and **fork-skiko** (mingw,
+`com.bitsycore.skiko:skiko`) legs - two different artifacts, so the shared parent can carry neither.
+
+**Why it's feasible NOW (all-skiko + srcDir reuse):** every native leg already reaches
+`src/skikoRendererMain/kotlin` (mingw via `kotlin.srcDir(...)` in `skikoRendererMingwSharedMain`,
+`ui-text/build.gradle.kts:54`), and the fork exposes the SAME `org.jetbrains.skia.*` Kotlin API. So
+the `Paragraph` **actual + engine can move DOWN into the skiko source set** (served to all targets)
+instead of skiko-free `nativeMain` - which lets upstream's skiko files compile as-is.
+
+**⚠️ SPIKE FINDING (2026-08-04) - the real gate is the FONT LOADER, not the source-set move.**
+A read-only feasibility map (no code changed) found two layers:
+- **Layer 1 - source-set / sealed move: FEASIBLE.** The `actual sealed interface Paragraph`
+  (`vendor/native/Paragraph.native.kt:36`, signature-only mirror) + its implementer + the 11 factory
+  actuals can move to `skikoRendererMain` (all leaves reach it; sealed same-source-set holds). Just
+  mechanical.
+- **Layer 2 - font model: THIS is the blocker, and it's the SAME task as §2-P1 `PlatformFontLoader`.**
+  Upstream's engine (`SkiaParagraphIntrinsics.skiko.kt:38,61`) resolves typefaces through
+  `FontFamily.Resolver` → `PlatformFontLoader`. The port's `SdlPlatformFontLoader`
+  (`font/FontFamilyResolver.native.kt:30-49`) is a **NOP** (`loadBlocking`/`awaitLoad`→`Unit`,
+  `resolve`→`Immutable(Unit)`). The port's hand-rolled engine exists precisely to BYPASS that NOP by
+  resolving through `SkiaFonts` (icon fonts + variable axes + data.kres bytes). So vendoring the
+  upstream engine verbatim routes font resolution through the NOP → **all text goes blank/tofu**
+  until the loader is real.
+- **Consequence:** the verbatim engine-vendor REQUIRES first implementing upstream's font-loader path
+  (vendor `SkiaFontLoader.skiko.kt` as the reference) so the port's `SkiaFonts` icon/variable-axis
+  model rides upstream's `PlatformFontLoader`/`FontLoadResult` seam. This is the deferred high-risk P1
+  in §2 - it and this §6 are one effort. **Intermediate option:** vendor the engine files but keep
+  `SkiaFonts` via a Rule-3 edit at the one resolve call site (vendors most files verbatim, 1–2 stay
+  hand-reconciled). **Verification needs macOS + Linux hosts** (parity), so this is a dedicated
+  effort, not a Windows-only session - do it with mac access, on its own branch.
+
+**Plan (spike on a branch, verify on THIS Windows host - build + render mingwX64):**
+1. Move the `Paragraph`/`ParagraphIntrinsics` **actuals** into `skikoRendererMain` (reused by mingw
+   via the existing `srcDir`). Confirm the `expect sealed` actual is accepted there for every leaf
+   target (the b63 memo hit a sealed-in-`nativeMain` wall - test whether hosting the actual in the
+   skiko set clears it; the sealed same-module rule is per-target-compilation, which should hold).
+2. Vendor VERBATIM into `src/vendor/skikoRenderer/`: `SkiaParagraph.skiko.kt`,
+   `ParagraphBuilder.skiko.kt`, `SkiaParagraphIntrinsics.skiko.kt`, `SkiaTextPaint.skiko.kt`,
+   `ParagraphLayouter.skiko.kt`, `PlatformFont.skiko.kt`, `FontRasterizationSettings.skiko.kt`,
+   `TextStyle.skiko.kt`; add them to `ui-text/compose-fork.txt`; delete the hand-rolled files.
+3. Reconcile the ~7 hierarchy-crossing `expect/actual` pairs the inverted layout needed; keep the
+   `SkiaFonts` family/variable-axis model (it's the port's real value-add) behind upstream's seams.
+4. **Fork-only Rule-3 edit:** upstream's code calls `paragraph.lineMetrics` - the fork's extern-C
+   binding mis-decodes ascent/descent (§1b finding). Either carry the guarded reconstruction (from
+   `SkiaParagraphOps.lineMetrics()`) into the vendored `SkiaParagraph.skiko.kt` as a Rule-3 edit, or
+   fix it in the fork DLL. **Bonus:** vendoring `ParagraphBuilder.skiko.kt` verbatim wires
+   `halfLeading` → the §1b M3-baseline drift disappears for free.
+5. Verify: mingwX64 build + `--screen=BasicText/Buttons/AnnotatedString` render clean +
+   `--metricsprobe` == JVM `--metrics`. Then macOS/Linux verify + parity (needs those hosts).
+
+**Sequencing:** AFTER the current shared-Kotlin fixes land (this session). If the sealed-actual move
+proves infeasible, fall back to keeping the seam but at least converting the hand files to tracked
+Rule-3 vendors (like `FontRasterizationSettings.native.kt` now has a `VENDOR-BASE` line).
+
+## Accepted 1.0.0 gaps (documented, not fixed)
+
+Drag-OUT of window (SDL platform limit; drop-IN works), full accessibility pipeline (out of
+scope for desktop 1.0 - but ship the non-throwing `PlatformScreenReader` no-op), the
+hand-rolled text engine as an architectural deviation (§2 P1), per-focus
+`SDL_StartTextInput/StopTextInput`, `loadImageBitmap`/`loadSvgPainter` (JVM `InputStream`
+signatures, N/A on K/N).

-## 1. The renderer
-
-> **This branch is Skia-only.** The from-scratch SDL renderer leg
-> (`sdlRendererMain`: `Sdl3Canvas` / `Sdl3TextRenderer` / `FreeTypeIcons` / the
-> SDL render nodes, ~3,800 lines) and its `SDL3_ttf` / `SDL3_image` / FreeType
-> cinterops were removed once Skiko-on-mingwX64 landed (Route 1a — see
-> [SKIKO-MINGW-FEASIBILITY.md](SKIKO-MINGW-FEASIBILITY.md)). SDL3 remains as the
-> windowing / input / platform layer only. Below, references to "the SDL leg", a
-> second `RenderBackend` actual, `-Prenderer=sdl3`, and the SDL-leg fidelity work
-> are **historical** — kept because the convergence decisions still explain the
-> Skia leg's shape.
-
-Rendering goes through one `RenderBackend`, implemented once: the **Skia leg**
-(`skikoRendererMain`). It draws through upstream Compose Multiplatform's own Skia
-stack, vendored verbatim: `SkiaBackedCanvas`, `SkiaBackedPaint`, `SkiaShader`,
-`actual class GraphicsLayer` backed by `org.jetbrains.skiko.node.RenderNode`,
-`SkiaGraphicsContext` — the layer and draw engine internals are literally
-upstream. macOS/Linux link the official Skiko klibs; mingwX64 links the
-bitsycore skiko **fork** (`skikoRendererMingwMain`, Route 1a).
-
-The text and image pipeline (`SdlParagraph`, `NativeTextMeasurer`, `IconFont`)
-is the port's own engine; glyph rasterization is Skia. GPU path per platform:
-Metal (macOS), OpenGL (Linux + Windows), with a CPU-raster `Software` fallback.
-
-The seam is kept as narrow and low as possible. Code flows
-`Common (upstream) -> shared native engine -> Skia actual / SDL actual`. What we
-minimize is hand-rolled actual surface, not actual-side line count: a fat
-vendored-upstream actual (the Skia leg carrying upstream's whole GraphicsLayer
-stack) is preferred over a thin hand-written one.
-
-## 2. The retained-layer engine (the model we copied)
-
-Upstream skiko skips work at three levels. The Skia leg has all three.
-
-- **L1 frame scheduling.** A frame schedules the next only if still dirty.
-  Ours: `ComposeWindow.shouldRender()` gates `renderFrame()`; the loop blocks on
-  `SDL_WaitEventTimeout` when idle.
-- **L2 measure/layout only dirty nodes.** Vendored `MeasureAndLayoutDelegate`
-  used verbatim through `ComposeOwner.measureAndLayout()`.
-- **L3 draw record-once / replay** (the expensive one). Each isolated
-  `LayoutNode` gets an `OwnedLayer` (`GraphicsLayerOwnerLayer`) owning a
-  `GraphicsLayer`. The display list re-records only when content is dirty;
-  otherwise it replays.
-
-The critical property: **transform, alpha, and clip changes do NOT re-record.**
-Moving, scaling, rotating, or fading a layer replays cached content under a new
-transform. Only a genuine content change (a state read inside the draw block, or
-a resize) re-records. Upstream replays the whole scene every frame with no
-dirty-region present; the entire win is not re-recording clean layers, not
-drawing less screen. Dirty-region rendering is therefore an explicit non-goal.
-
-The compositing-strategy contract (`requiresLayer()`, from
-`SkiaGraphicsLayer.skiko.kt`) decides when a layer needs an offscreen:
-
-| Condition | Auto | Offscreen | ModulateAlpha |
-|---|---|---|---|
-| `alpha < 1` | offscreen | offscreen | per-op alpha multiply (no offscreen) |
-| `colorFilter != null` | offscreen | offscreen | offscreen |
-| `blendMode != SrcOver` | offscreen | offscreen | offscreen |
-| `renderEffect != null` | offscreen | offscreen | offscreen |
-| none of the above | replay in place | always offscreen | replay in place |
-
-## 3. Current state
-
-- **Skia leg runs upstream's engine.** Canvas (`SkiaBackedCanvas`) and
-  GraphicsLayer/GraphicsContext (`org.jetbrains.skiko.node.RenderNode`) are
-  vendored verbatim. The Skia leg gets real display-list caching and correct
-  clip/shadow/renderEffect for free from upstream. After this landed, Skia
-  `draw` on LazyColumn fell from 1.75 ms to 0.2 ms.
-- **Parity is a golden-master against JVM** (about 2% median, dominated by the
-  shared text engine's small metric delta). See TOOLING.md for how to read it.
-- **Memory is stable.** The historical composition leak is fixed (see section 6)
-  and guarded by the `--soaktest` gate in the verify runbook.
-
-## 4. Decisions to remember
-
-- **Goal is G1, cheap upstream-tracking.** The target is low per-bump
-  reconciliation cost when following upstream. All platforms now render through
-  real Skia — mingwX64 via the bitsycore skiko fork (Route 1a; see
-  [SKIKO-MINGW-FEASIBILITY.md](SKIKO-MINGW-FEASIBILITY.md)) — so there is no
-  fidelity tier below the JVM cross-check. The JVM Compose Desktop target
-  (`:demo:run`) remains the fidelity/parity reference on any host.
-- **Vendor, do not hand-roll.** Copy upstream verbatim wherever it compiles.
-  Edit-to-compile becomes a manual vendor with a `// VENDOR-BASE:` header so the
-  drift tripwire can track it. The litmus test for any divergence: "Is this what
-  upstream does? If not, what real platform constraint forces the difference?"
-  Valid answers name a constraint (e.g. no windowing/input toolkit in K/N ->
-  SDL3). "It was easier" is not valid.
-- **Text stays the port's engine (B6.3 skipped).** Making Skia-leg text truly
-  upstream (`SkiaParagraph`) is a font-subsystem replacement, not a canvas swap:
-  two coexisting font-identity models (the port's name-to-bytes `IconFont` +
-  no-op resolver vs upstream `PlatformFont`/`FontCache`/`FontCollection`), about
-  13 skiko files to re-vendor, about 10 shared actuals to split, a
-  `data.kres`-to-`FontCache` bridge, no green intermediate, and it discards the
-  P3.1 metrics work. ROI is low: the Skia leg already measures text with skiko
-  `Font` metrics (via `currentTextMeasurer` -> `SkiaTextRenderer`), which is how
-  parity reached about 2%. Revisit only if complex-script/bidi fidelity becomes
-  a hard requirement.
-- **Module split (`:ui-graphics` / `:ui-text`) is shelved as infeasible.** Not
-  cosmetic churn as originally scoped: the `sdl3` cinterop is a shared substrate
-  used by 11 graphics-side files AND 12 platform/windowing/node/resources files
-  that stay in `:ui`. Kotlin/Native cannot cleanly share a cinterop klib across a
-  module boundary, which is exactly why they were merged. A real split needs a
-  new non-upstream `:ui-cinterop` base module plus cross-module cinterop
-  api-exposure, which is bigger and more divergent than the "match upstream
-  artifacts" goal it was meant to serve. The one keeper from the attempt:
-  `RenderBackend.drawRoot` now takes `(Canvas) -> Unit`, decoupling the backends
-  from `ComposeRootHost` (a genuine improvement, retained).
-- **Real Skia on Windows K/N shipped (Route 1a).** mingwX64 links the bitsycore
-  skiko fork against `skiko-windows-x64.dll` (with an embedded GNU import lib),
-  published to GitHub Packages and auto-provisioned by the bridge plugin. This
-  replaced the SDL renderer as the Windows path. See
-  [SKIKO-MINGW-FEASIBILITY.md](SKIKO-MINGW-FEASIBILITY.md) for the ABI details
-  and the route trade-offs.

-## 6. Remaining and future work
-
-Nothing here blocks day-to-day work. These are the open threads worth
-remembering.
-
-- **WIN-SMOKE (pre-ship, Windows only).** The Mac runbook cannot cover the
-  shipped mingwX64 binary, the Windows-only `PrintWindow` probe, or the
-  common-metadata publish job. Run these on a Windows host before any release.
-  This is the only outstanding verification.
-- **Stabilization at Compose 1.12.0 stable.** The vendored refs are pinned to
-  `v1.12.0-beta03+dev4483` (no clean beta03 tag exists yet, and it is not on
-  Maven). The native side leads the JVM parity leg (forced to beta02, the latest
-  published) by a documented skew. When 1.12.0 stable ships: re-pin both refs to
-  the clean tag, bump the `vComposeJvmVersion` forcing in demo/apidemo/
-  material-symbols to close the skew, then cut the release. The concrete
-  step-by-step (the version map, the ref-bump flow, and the release flow) lives
-  in [TOOLING.md](TOOLING.md#versioning-and-releasing).
-- **Deferred engine deltas (D2-D6, all low ROI under G1).**
-  - D2: split `GraphicsLayerOwnerLayer` per-leg to restore upstream's exact
-    `setLightingInfo` shadow lighting. Feasible (the old RootNodeOwner-coupling
-    blocker was outdated) but high blast radius for a marginal gain; elevation
-    shadows already match JVM.
-  - D3: dedupe `LayerTransformationMatrix.kt` against the now-vendored
-    `Matrices.skiko`. Blocked on D2 (the shared owner-layer hit-test needs a
-    matrix fn usable from the owner layer).
-  - D4/D5: `SemanticsRegion` intersect/difference are stubs, and `CharHelpers`
-    is naive grapheme/bidi vs upstream ICU. Real fidelity gaps, gated on an
-    accessibility or complex-script roadmap.
-  - D6: `Focusability` / `PlatformVelocityTracker` are byte-equal to upstream;
-    vendoring them saves nothing.
-- **Native-resource lifecycle.** Wire `GraphicsLayer`/RenderNode +
-  `SdlImageBitmap.close()` fully into cache eviction and the renderer
-  `destroy()` chain; demote the periodic GC nudge once ownership covers it.
-
-## 7. Hard-won learnings (do not relearn)
-
-- **Minimize-divergence is load-bearing.** A hand-written `notifyLayerIsDirty`
-  that diverged from upstream `OwnedLayerManagerImpl` removed a layer from
-  `dirtyLayers` mid-loop and crashed on any navigation. Screenshots missed it;
-  the interaction probe caught it. Match upstream verbatim; do not hand-roll
-  engine plumbing from a summary.
-- **The composition memory leak (root cause).** The port never called
-  `OwnerSnapshotObserver.clearInvalidObservations()`, which upstream
-  `RootNodeOwner` runs after every measure. Snapshot read-observations for
-  scopes invalidated on dispose lingered forever, each pinning its observed
-  object graph via a Kotlin/Native `ExternalRCRef` (a K/N-heap leak, vmmap
-  Memory Tag 246). Most visible on ripple/indication draws. Fix:

-# Skiko on mingwX64 — Feasibility & Effort Assessment
-
-Investigation of the effort to run the real Skia leg (`org.jetbrains.skiko`)
-on the Kotlin/Native **mingwX64** target, under the relaxed constraint that a
-**DLL is acceptable** (the static / no-DLL invariant may be dropped). Companion
-to [RENDERER.md](RENDERER.md) §4 "Track A" — which this assessment **partly
-supersedes** (see [Corrections](#corrections-to-renderermd-4) below).
-
-Pins at time of writing: skiko `0.150.1` (Skia m150), kotlin `2.4.0`,
-compose `1.12.0-beta02`.
-
----
-
-## Bottom line
-
-Feasible — and **more tractable than RENDERER.md §4 claims**. Two of that
-section's load-bearing premises are now factually stale:
-
-1. **"Building C++20 Skia to a GNU/mingw archive is an open-ended fork (only
-   abandoned Mozilla-era precedent)."** — **False.** MSYS2 maintains
-   `mingw-w64-skia` at **Skia milestone 143 (C++20)** for `mingw64` (GCC),
-   `ucrt64`, and `clang64` (clang → `x86_64-w64-windows-gnu`), producing
-   `libskia.dll` + a GNU import lib `libskia.dll.a`. Last rebuilt **2026-07-24**.
-   The GNU-ABI recipe is ~8 small GN patches (the key one adds
-   `is_mingw = is_win && (cxx=="g++"||cxx=="clang++")`).
-2. **"The only working route is a runtime DLL, which breaks the no-DLL
-   invariant."** — The DLL route is real, but the reason it works is **not**
-   what the section implies. See the crux below.
-
-**Effort:** ~**1–2 weeks** to a proven spike + a CPU-raster Skia-on-Windows
-prototype; ~**1–2 months** to a tested, GPU-accelerated Windows Skia leg with
-published fork klibs and repo wiring — **plus** permanent
-`bitsycore/skiko`-fork maintenance (re-sync at every skiko bump). Difficulty:
-**research-grade / high**, because no working prior art exists (the two GitHub
-`skiko-mingw64` forks are vaporware — 0 commits ahead of upstream, no mingw
-source set). Confidence: **medium** (high on mechanism, medium on timeline).
-
----
-
-## Spike result — EXECUTED, GREEN ✅ (2026-07-24)
-
-The core de-risking experiment has been **run on this machine** and passed. The
-whole Route 1a link mechanism works on the exact target toolchain (Kotlin
-**2.4.0**, mingwX64, LLVM **21** `ld.lld`, `x86_64-pc-windows-gnu`).
-
-**What was built** (`spike-skiko-mingw/` in this repo):
-- A tiny DLL reproducing skiko's binding shape — an **opaque handle over a real
-  C++/STL object** (`std::string`), **alloc+free paired inside the DLL**, flat
-  `extern "C"` surface. Compiled **MSVC-ABI via `clang-cl /LD /MT /EHsc`**
-  (static CRT). Exports verified undecorated: `spike_make/size/free`.
-- A **GNU import library** (`libspike.dll.a`) generated with `dlltool`.
-- A **Kotlin/Native mingwX64 executable** binding it via cinterop (plain C
-  header) + `linkerOpts("-L… -lspike")`.
-
-**Results:**
-- `linkReleaseExecutableMingwX64` **linked clean** — **KT-65671 did NOT bite**
-  (the DLL path puts zero C++ objects in the K/N link graph, so the
-  `--allow-multiple-definition` / `.drectve __clang_call_terminate` failures
-  never arise). LLVM 21 `ld.lld` is also far newer than the 1.9.x-era reports.
-- Runtime: `SPIKE-RESULT size=7 expected=7 ok=true`, exit 0 — the C++
-  `std::string(7,'x').size()` round-trips through the opaque handle correctly.
-- `objdump -p` confirms the exe imports `spike.dll`, and `spike.dll` depends on
-  **`KERNEL32.dll` only** → **self-contained, no VC++ redist needed**. The exe
-  carries K/N's `msvcrt.dll` while the DLL carries its own static MSVC CRT —
-  **two CRTs coexist in one process** with no issue (ownership paired inside the
-  DLL), empirically confirming the CRT-boundary discipline.
-
-**Implication:** the one load-bearing unknown (does the DLL route link on
-2.4.0?) is resolved **in favour**. Route 1a is de-risked at the mechanism level;
-remaining effort is engineering the real `skiko.dll` (compile skiko's shim +
-skia-pack MSVC Skia into one DLL) and repo wiring — not proving feasibility.
-Feasibility confidence is now **high**; residual medium confidence is on
-timeline only.
-
-Reproduce: `./gradlew -p spike-skiko-mingw linkReleaseExecutableMingwX64`, then
-run the exe with `spike-skiko-mingw/native` on `PATH`.
-
----
-
-## The crux — and why "just use a DLL" is only half the story
-
-**The blocker is a C++ ABI mismatch at the binding boundary, and it is
-orthogonal to static-vs-dynamic linkage.**
-
-- **K/N mingwX64 is GNU/Itanium ABI.** `konan.properties`:
-  `targetTriple.mingw_x64 = x86_64-pc-windows-gnu`,
-  `linker.mingw_x64 = ld.lld.exe`,
-  `linkerKonanFlags.mingw_x64 = -static-libgcc -static-libstdc++ … -lwinpthread`
-  — GCC libstdc++/libgcc, Itanium mangling (`_Z3fooi`).
-- **skia-pack's only Windows Skia is MSVC-ABI** — built with `clang-cl`,
-  `is_trivial_abi=false`, shipped as MSVC `.lib`; C++ exports are MSVC-mangled
-  (`?foo@@YAHH@Z`).
-
-LLVM issue #60847 ("LLD cannot link against MSVC libraries in MinGW toolchain",
-closed *not planned*) confirms the two mangling schemes never reconcile.
-**Wrapping the same MSVC C++ Skia in a DLL does not change this** — a DLL's C++
-exports are still MSVC-mangled. So dynamic-vs-static is a red herring; **the C++
-ABI at whatever boundary the mangled C++ crosses is the wall.**
-
-What makes it tractable is *where that boundary sits in skiko*:
-
-- **skiko's Kotlin↔native boundary is already a flat, unmangled C symbol
-  boundary.** Kotlin declares
-  `@ExternalSymbolName("org_jetbrains_skia_Data__1nSize") external fun _nSize(…)`;
-  `ExternalSymbolName` is a typealias for `kotlin.native.SymbolName`, which
-  resolves to a *plain named symbol* at link. The generated `.def` is
-  header-less (only `linkerOpts`). **No C++ type ever crosses into Kotlin.**
-- **The C++ ABI coupling lives one layer down**, at the *shim↔Skia* link:
-  ~78 `extern "C"` (`SKIKO_EXPORT`) `.cc` files under `src/nativeJsMain/cpp/`
-  that `reinterpret_cast<SkData*>(ptr)->size()` etc. This shim **must share one
-  C++ ABI with Skia** — today they're one GNU-ABI island fused via
-  `-include-binary`.
-
-**Consequence:** a DLL is viable **iff** the *entire* C++ island (shim + Skia)
-is one consistent ABI internally, and only the **flat extern-C export surface**
-crosses to K/N via a generated import library. On x86_64 there is a single
-Windows calling convention and extern-C exports are undecorated on both MSVC and
-mingw, so `ld.lld` links such a DLL via `gendef`+`dlltool` (or directly, LLD
-13+). **The repo already does exactly this for system DLLs** (`sdl3.def`:
-`linkerOpts.mingw_x64 = -lkernel32 -luser32 -lgdi32 …`).
-
-Crucially the extern-C façade **already exists** (the `nativeJsMain/cpp` shim
-exports precisely the `org_jetbrains_skia_*` symbols the K/N side binds) — it is
-**reused, not authored anew**. The catch: no ownership / exceptions / STL may
-cross the C line — skiko is already handle/RefCnt-based, so this holds if
-authored carefully. (The JVM `jvmMain/cpp` bridge exports `Java_…` JNI symbols
-and is **not** reusable — the *native* shim is the right one.)
-
-The non-negotiable that survives all of this: **upstream skiko ships no
-mingwX64 K/N target at all** (`throw GradleException("$os not yet supported")`
-for non-{Mac,iOS,tvOS,Linux}; "Windows" in skiko means the JVM/AWT clang-cl
-path). So this is a **from-scratch skiko build-system port**, not a flag flip.
-
----
-
-## The dominant risk: KT-65671
-
-`KT-65671` ("Kotlin/Native: Failed linking cinterop static library for
-mingwX64", **Open**, filed against 1.9.x, status on 2.4.0 unverified): K/N's
-mingw link step chokes when **fusing an external C++ static archive** —
-`ld.lld` rejects `--allow-multiple-definition`, and
-`-exclude-symbols:__clang_call_terminate` in the objects is rejected in
-`.drectve`. This is skiko's **exact static-fusion pattern**.
-
-Key implication for route choice: a **pure extern-C DLL boundary sidesteps this
-bug class entirely** — no C++ objects enter the K/N link graph; only a flat
-import surface crosses. So, counter-intuitively, the **DLL route is the
-risk-*reducing* route** w.r.t. KT-65671, and it is exactly what the user is
-willing to accept.
-
----
-
-## Routes
-
-### ★ Recommended — DLL with a flat extern-C export, K/N binds via import lib
-
-Put **all** the C++ (skiko's existing shim + Skia) inside one DLL; export only
-the flat `org_jetbrains_skia_*` symbols; bind from a new mingwX64 skiko target
-via a generated import lib. K/N resolves at link; the Windows loader binds
-`skiko.dll` at process start — **no dlopen/`staticLoad` code needed** (the
-shipped `staticLoad()` no-op is fine for the import-lib path).
-
-Two sub-choices for the DLL internals (K/N neither knows nor cares which):
-
-- **1a — MSVC internals (minimal fork).** Recompile skiko's `nativeJsMain/cpp`
-  shim with `clang-cl` against **skia-pack's existing MSVC Windows `.lib`**
-  (`windows-x64` archives are already published). **Zero Skia fork.** Net-new:
-  add `__declspec(dllexport)` to `SKIKO_EXPORT` on this build, a mingw/DLL
-  branch in skiko's build logic, import-lib generation. CRT discipline (MSVC CRT
-  in the DLL vs K/N's static libgcc) is a correctness constraint on the C API
-  (handles + primitives only), not a linkability blocker.
-- **1b — GNU internals.** Build the shim + Skia GNU-ABI (reuse MSYS2's
-  `mingw-w64-skia` patch set) into the DLL. Slightly more Skia-side work, but a
-  single toolchain end-to-end.
-
-**Effort:** ~2–4 weeks once the spike is green. **Risk: medium** (sidesteps
-KT-65671). **"Just works" preserved:** none — ships `skiko.dll` (tens of MB)
-next to `data.kres` (accepted). **Sub-choice 1a is the least-fork option.**
-
-### Route 2 — GNU-ABI static Skia + real mingwX64 skiko target (purist)
-
-Fork skia-pack (or reuse MSYS2's patches) to emit **GNU-ABI static** Skia;
-fork skiko to add a mingwX64 target that recompiles the existing extern-C shim
-GNU-ABI and **static-fuses** exactly as macOS/Linux do today.
-
-**Effort:** Skia build itself is now **days** (MSYS2 proves it). skiko port +
-link reconciliation ~3–6 weeks. **Risk: medium-high** — this route hits
-**KT-65671 head-on** (static C++ archive fusion). **Preserves the static /
-no-DLL invariant** — the only reason to prefer it, and the user said they don't
-need it.
-
-### Route 3 — CPU-raster-only (a scope reduction, not an ABI shortcut)
-
-The repo's `SkiaSurfaceBridge` (`Surface.makeRasterDirect` → `SDL_UpdateTexture`
-→ `SDL_RenderTexture`) needs **no GPU context** and compiles on mingwX64 the
-moment a skiko klib exists. Use it to **skip authoring the Windows GPU bridge**
-for a first cut. Still requires solving Route 1/2's binding problem first.
-**Saves ~1–2 weeks** of GPU-bridge work → the natural **milestone 1** of
-whichever route you pick.
-
-### Baseline — do nothing (already shipping)
-
-Windows renders via the from-scratch **SDL leg** (`SDL_RenderGeometry` +
-SDL3_ttf + FreeType); the **JVM parity target** is the full-fidelity Skia
-reference. The bar any Skia-on-Windows work must clear is "materially better
-than the SDL leg's fidelity, worth the DLL + maintenance cost."
-
----
-
-## Recommended work breakdown (Route 1a, CPU-raster first)
-
-**A. Skia — none (1a) / days (1b).**
-Route 1a reuses skia-pack's published `windows-x64` MSVC `.lib`. (1b: reuse the
-MSYS2 `mingw-w64-skia` PKGBUILD + patches at skiko's pinned milestone; backends
-CPU-raster + `skia_use_gl`, `skia_use_freetype`.)
-
-**B. `bitsycore/skiko` fork — the bulk, medium risk.**
-1. Add `mingwX64()` + a `configureNativeTarget(OS.Windows, Arch.X64, …)` branch;
-   replace the `throw GradleException("$os not yet supported")` / empty
-   `linkerFlags` fall-throughs in `NativeTasksConfiguration.kt` with a Windows
-   branch (PE/COFF, `llvm-ar`).
-2. Compile the **existing** `nativeJsMain/cpp` shim (not the JVM JNI bridge)
-   into `skiko.dll`; make `SKIKO_EXPORT` export the flat symbols
-   (`__declspec(dllexport)` or `--export-all-symbols`/def file).
-3. Generate the GNU import lib (`gendef` + `dlltool` → `libskiko.dll.a`).
-4. cinterop `.def` stays header-less (`linkerOpts`/`libraryPaths`), matching the
-   repo's own idiom. Publish mingwX64 klibs + the DLL.
-
-**C. Windows context actual — deferred behind milestone 1.**
-5. **Milestone 1:** wire only the CPU-raster `SkiaSurfaceBridge` (already
-   Windows-ready).
-6. **Milestone 2:** author `SkiaD3D11Bridge` / `SkiaVulkanBridge` — extract HWND
-   via `SDL_GetWindowProperties`, wrap `DirectContext.makeD3D11`/`makeVulkan`,
-   mirror the Metal/GL bridges' per-frame acquire/present.
-
-**D. This repo's wiring — small, low risk (integration points confirmed).**
-7. `compose/ui/ui/build.gradle.kts` — flip `isSkiaTarget("mingwX64")` to `true`
-   (currently hardcoded `false`, ~line 58); create a `skikoRendererMingwMain`
-   and `mingwX64Main.dependsOn(...)` it (today mingw attaches only to
-   `sdlRendererMingwMain`, lines ~203–206; the skiko tree, lines ~220–235, is
-   created only under `!useSdl3Everywhere` and never for mingw). Add the fork's
-   coords to that source set.
-8. **No new expect/actual needed:** `createRenderBackend` /
-   `rendererPreferredGpuMode` are `expect`s in `nativeMain` with `actual`s in
-   `skikoRendererMain` and `sdlRendererMain`; attaching mingwX64 to the skiko
-   source set makes the Skia actual resolve for Windows (one renderer source set
-   per target — the existing invariant).
-9. Add a Windows GPU-bridge branch to `rendererPreferredGpuMode()`; verify with
-   the demo/apidemo (`--gpu`, `--screenshot`) and the parity harness.
-
-Repo surface to cover is narrow: **~67 `org.jetbrains.skia` classes + 5
-`org.jetbrains.skiko.node` APIs** (`RenderNode`, `RenderNodeContext`,
-`SkikoRenderDelegate`, `SystemTheme`, `currentSystemTheme`).
-
----
-
-## The one spike to run first (~1–2 days)
-
-Before any fork work, **empirically test the K/N-mingw link path**: build a
-trivial `extern "C"` C++ DLL (one function returning a handle + one that uses
-it) — or consume MSYS2's `mingw-w64-x86_64-skia` DLL + `libskia.dll.a`
-directly — from a throwaway mingwX64 K/N project via cinterop + import lib, and
-**run it**. This answers, in a day instead of a month:
-
-- Does K/N mingw link + call a GNU-ABI DLL via an import lib at all?
-- Does **KT-65671** reproduce on Kotlin 2.4.0 (import-lib vs static fusion)?
-- DLL vs static-fusion behaviour on this toolchain.
-
-If green, Routes 1/2 are de-risked. (Caveat: MSYS2 Skia exports Skia's *mangled
-C++* symbols, so a direct cinterop of it tests only the *link mechanism*, not
-the skiko API — for the API you still need the extern-C shim. The trivial-C-DLL
-variant is the cleaner mechanism test.)
-
----
-
-## Biggest risks / unknowns
-
-1. **KT-65671** — whether K/N's mingw link works on 2.4.0 for external C++;
-   the DLL route sidesteps it, the static route hits it. *The single fact that
-   swings the effort.*
-2. **Toolchain matching** — Konan bundles LLVM 16 clang + `ld.lld`; the C++20
-   Skia + shim must be built by a toolchain whose objects/imports LLD accepts.
-3. **CRT / ownership discipline** across the C boundary (only matters for 1a).
-4. **Maintenance** — SKIKO-446 / SKIKO-611 are Open, unassigned → almost
-   certainly a **permanent `bitsycore/skiko` fork** with per-bump re-sync tax.
-
----
-
-## Recommendation
-
-Pursue **Route 1a** (skiko fork producing a DLL with a flat extern-C export over
-skia-pack's existing MSVC Windows Skia), **scoped CPU-raster first** (Route 3
-milestone), GPU bridge second. It matches the user's accepted DLL tolerance,
-requires **zero Skia fork**, and **dodges KT-65671**. Keep Route 2 (static,
-GNU-ABI) in reserve only if reclaiming the no-DLL invariant later becomes
-valuable. **Run the MSYS2/trivial-DLL spike before committing to any fork.**
-
----
-
-## Implementation status — WORKING END-TO-END ✅ (2026-07-24)
-
-**`demo.exe` (mingwX64) renders the Material 3 Buttons screen through real Skia**
-and wrote a 1000×700 screenshot ("settled at frame 3"), using the CPU-raster
-`SkiaSurfaceBridge` backed by the forked `skiko-windows-x64.dll`. Route 1a is
-complete. Build/run:
-
-```
-# fork (C:/Dev/skiko), one-time env: SKIKO_VSBT_PATH=<VS BuildTools dir>
-./gradlew :skiko:publishKotlinMultiplatformPublicationToMavenLocal \
-          :skiko:publishMingwX64PublicationToMavenLocal -Pskiko.native.windows.enabled=true
-# compose repo
-./gradlew :demo:linkDebugExecutableMingwX64 -PwindowsSkia=true
-cp <fork>/skiko/build/out/link/Release-windows-native-x64/skiko-windows-x64.dll <demo exe dir>/
-<demo exe dir>/demo.exe --screenshot=out.bmp --screen=Buttons
-```
-
-Fork fixes needed beyond the DLL build (skiko uses a CUSTOM hierarchy template,
-`applyDefaultHierarchyTemplate=false`):
-1. `sourceHierarchy.kt` — add `group("windows"){ withMingwX64() }` under `native`
-   (else the mingwX64 klib compiles EMPTY — missing all of `org.jetbrains.skia`).
-2. `SkikoProjectContext` — add `supportNativeWindows` into `supportAnyNative` so
-   the `@SymbolName` opt-in reaches the mingw compile.
-3. `Resources.native.kt` — `ftell` is 32-bit `Int` on Windows (LLP64); `==` fix.
-4. `windowsMain` actuals for `SkiaLayer` / `currentSystemTheme` (linux is a stub).
-5. Force-export the 2 ICU symbols (`uloc_getDefault_skiko`,
-   `uloc_toLanguageTag_skiko`) that Kotlin binds via `@SymbolName`.
-
-Compose-repo wiring (all behind `-PwindowsSkia=true`): `mavenLocal()` in
-settings, `isSkiaTarget("mingwX64")`, a separate `skikoRendererMingwMain` tree
-on the fork's **root** coord (`org.jetbrains.skiko:skiko:0.0.0-SNAPSHOT` — the
-platform artifact alone doesn't expose api-elements), `PlatformGpu` Windows →
-`Software`, and a one-line `PlatformGpu.mingw.kt`.
-
-## Earlier milestone — fork BUILDS ✅ (2026-07-24)
-
-Route 1a is not just designed — the `bitsycore/skiko` fork now **builds the
-native Windows Skia DLL + a mingwX64 klib** on this machine (`C:/Dev/skiko`,
-skiko `v0.150.1`).
-
-Edits made (all in the fork):
-- `src/nativeJsMain/cpp/common.h` — `SKIKO_EXPORT` gains `__declspec(dllexport)`
-  under a `SKIKO_WINDOWS_DLL` guard.
-- `skiko/build.gradle.kts` — `configureNativeTarget(OS.Windows, Arch.X64,
-  mingwX64())`, gated behind `-Pskiko.native.windows.enabled=true`.
-- `buildSrc/.../NativeTasksConfiguration.kt` — a Windows compile branch
-  (clang-cl + `-DSKIKO_WINDOWS_DLL`) and a new `configureWindowsNativeTarget`
-  that links `skiko-windows-x64.dll` via `lld-link` (reusing the JVM template +
-  `resolveBinaryInputs(…, TargetEnv.JVM, …)`), auto-generates the GNU import lib
-  (`dumpbin`→`.def`→`dlltool`), and wires the K/N cinterop `linkerOpts`.
-
-Results:
-- The native bridge (`nativeJsMain/cpp`) **compiled on Windows with clang-cl,
-  zero source changes.** The only link fix was adding `d3d12.lib
-  d3dcompiler.lib dxgi.lib` for Skia's `SK_DIRECT3D` backend.
-- Produced **`skiko-windows-x64.dll` (14.2 MB, 1005 exported
-  `org_jetbrains_skia_*` symbols)**, `libskiko-windows-x64.dll.a` (GNU import
-  lib), and the **mingwX64 klib** (`build/classes/kotlin/mingwX64/main/klib`).
-
-Prerequisite for any skiko Windows build on this box:
-`SKIKO_VSBT_PATH='C:\Program Files (x86)\Microsoft Visual Studio\18\BuildTools'`
-(Gradle's VS locator doesn't auto-find VS 18 BuildTools).
-
-Remaining: publish the fork to `mavenLocal` → a tiny K/N mingw consumer that
-calls a real Skia function (links the import lib, runs with the DLL on `PATH`)
-for the definitive end-to-end proof → then wire the compose repo (flip
-`isSkiaTarget("mingwX64")`, add `skikoRendererMingwMain`, ship the DLL next to
-the exe, CPU-raster `SkiaSurfaceBridge` first). One known TODO: the klib's
-`linkerOpts` use an absolute import-lib path (fine same-machine; make relative /
-bundled for distribution).
-
-## Corrections to RENDERER.md §4
-
-The shelving note should be updated — its two central technical claims are stale
-as of 2026-07:
-
-- "GNU-ABI Skia is an open-ended fork / only abandoned Mozilla-era precedent" —
-  **false**: MSYS2 maintains a modern (m143, C++20) GNU-ABI Skia, rebuilt
-  routinely.
-- The accurate residual blocker is **the K/N-side link/binding port**
-  (KT-65671 + authoring the mingwX64 skiko target), **not** building Skia, and
-  the DLL route is *risk-reducing*, not merely "the only working route."

-
-Severity is a rough guide, not a mandate:
-
-- **Blocker** for stable: a capability a typical desktop app expects that is
-  currently absent or broken.
-- **Nice-to-have**: real gap, but the app works without it.
-- **Cosmetic**: minor fidelity or edge-case behavior.
-
-Context for prioritizing: the project goal is **G1, cheap upstream-tracking**
-(see [RENDERER.md](RENDERER.md)). There is now ONE renderer — **Skia**
-(macOS/Linux official Skiko; mingwX64 the bitsycore skiko fork), so Windows
-renders through real Skia. The priorities below are the cross-cutting platform
-gaps that affect every OS. JVM Compose Desktop remains a parity cross-check.
-
-Renderer-internal cleanups (the deferred D2 shadow-lighting split, D3 matrix
-dedupe) live in [RENDERER.md](RENDERER.md#6-remaining-and-future-work), not
-here.
-
-## Completed
-
-Platform / cross-cutting:
-
-- **Locale / i18n** (`5d03711f`) — `Locale.current` / `LocaleList.current` read the
-  OS locale via SDL, unlocking the 40+ Material 3 translations. The date/number
-  format tail remains (section C).
-- **IME text input** (`500c49e4`) — a real `PlatformTextInputSession` routes SDL
-  committed + composing text to the focused field (commit replaces the
-  composition); `SDL_SetTextInputArea` positions the OS candidate window.
-- **Cursor icons** (`1fcc0828`) — `Modifier.pointerHoverIcon` drives the OS cursor
-  via SDL (I-beam over text, hand over links).
-- **WindowInfo** (`bad23073`) — `isWindowFocused` + `containerSize` / `containerDpSize`
-  report real values (were hardcoded `true` / `Zero`).
-- **ImageBitmap from bytes** — `ByteArray.decodeToImageBitmap()` /
-  `createImageBitmap(bytes)` decodes encoded image bytes; was
-  `UnsupportedOperationException`. Verified `demo --imagebytestest`.
-- **`FontFamily.Monospace`** — generic families map to `"generic:<name>"`;
-  `registerGenericFonts` registers bundled NotoSansMono under `generic:monospace`
-  (bundled only when the app references it). Verified `demo --fonttest`.
-
----
-
-## Release-blocking shortlist for stable 1.12
-
-The cross-cutting items to weigh first (all detailed below):
-
-1. **No copy/paste context menu** (section B). Keyboard copy works; there is no
-   right-click or selection toolbar (the desktop path is the right-click context
-   menu, upstream TODO CMP-7819).
-2. **Accessibility is entirely absent** (section A). Decide whether stable
-   requires any screen-reader support at all.
-3. Fonts (section D): compose-resources `Font(Res.font.x)` works, and
-   `FontFamily.Monospace` now renders NotoSansMono. Remaining: `Serif`/`Cursive`
-   generics (no bundled font) and the androidx `Font(bytes)`/`PlatformFontLoader`
-   path. Nice-to-have, not a blocker.
-
----
-
-## A. Accessibility (entirely absent)
-
-No accessibility bridge exists. A real `SemanticsOwner` is built but never
-surfaced to any OS accessibility API (no NSAccessibility / UIA / AT-SPI, no SDL
-a11y). Screen readers get nothing.
-
-- `compose/ui/ui/src/nativeMain/.../node/impl/ComposeOwner.kt:340` · `semanticsOwner` is instantiated but never read; no traversal into a platform a11y tree. A real a11y controller would walk the semantics tree and map roles/labels/actions to a native AT bridge. **Blocker for a11y.**
-- `compose/ui/ui/src/nativeMain/.../platform/CompositionLocals.native.kt:31` · `LocalPlatformScreenReader` default throws (`error(...)`); never provided by any window. Screen-reader-active queries are unavailable. **Blocker for a11y.**
-- `compose/ui/ui/src/nativeMain/.../node/impl/ComposeOwner.kt:297` · `accessibilityManager` implements only `calculateRecommendedTimeoutMillis` (passthrough); no announce/focus/event surface. **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../semantics/SemanticsRegion.native.kt:14` · `StubSemanticsRegion.intersect()`/`difference()` hardcode `false`; only `set`/`bounds` work. Region math for semantics culling is inert. **Nice-to-have.**
-
-## B. Text toolbar and context menus (copy / paste / select-all)
-
-- `compose/ui/ui/src/nativeMain/.../node/impl/ComposeOwner.kt:311` · `textToolbar` is a stub: `showMenu`/`hide` NOP, `status` always `Hidden`. NOTE: the floating toolbar is gated on `isInTouchMode`, so on desktop (mouse) it never shows anyway — the desktop path is the right-click context menu below. **Nice-to-have (touch only).**
-- `compose/foundation/.../text/selection/SelectionActuals.native.kt:42` · `addSelectionContainerTextContextMenuComponents` NOP (upstream TODO CMP-7819). No right-click copy/select-all menu for `SelectionContainer`. **Blocker for desktop text UX.**
-- `compose/foundation/.../text/selection/TextFieldSelectionManager.native.kt:24` and `compose/foundation/.../text/input/internal/selection/TextFieldSelectionState.native.kt:36` · `addBasicTextFieldTextContextMenuComponents` NOP for both the legacy and state-based `BasicTextField`. **Blocker for desktop text UX.**
-
-## C. Locale / i18n tail (needs locale-aware DATA, no ICU on K/N)
-
-`Locale.current` / `LocaleList.current` are wired to the OS (see Completed). The
-rest needs month/weekday name tables and date/number patterns, which Kotlin/Native
-has no ICU for; SDL reports language + country only (no script subtag, no
-calendar/clock/number prefs). These require a bundled CLDR subset or a K/N i18n lib.
-
-- `compose/material3/.../CalendarLocale.native.kt:20` · locale-agnostic stub: `toString()` fixed `"en"`, single shared instance, `equals` treats all instances as equal. A separate type from `ui.text.intl.Locale`; needs its own wiring so `CalendarModel`/`PlatformDateFormat` can vary by locale. Inert until `PlatformDateFormat` is localized. **Nice-to-have (DatePicker/TimePicker).**
-- `compose/material3/.../internal/PlatformDateFormat.native.kt` · multiple hardcodes:
-  - `:27` `weekdayNames` hardcoded English full/short names (DatePicker shows English day initials regardless of locale). **Blocker for localized DatePicker.**
-  - `:32` `formatWithPattern`/`formatWithSkeleton` ignore the pattern/skeleton and always emit ISO `yyyy-MM-dd`. **Blocker for localized DatePicker.**
-  - `:25` `firstDayOfWeek` hardcoded `1` (Sunday); locale-dependent. **Nice-to-have.**
-  - `:44` `parse()` only accepts ISO `yyyy-MM-dd`, ignoring pattern/locale. **Nice-to-have.**
-  - `:62` `getDateInputFormat()` hardcoded `yyyy-MM-dd` / `'-'`. **Nice-to-have.**
-  - `:65` `is24HourFormat()` hardcoded `true`. **Cosmetic.**
-- `compose/ui/ui/src/nativeMain/.../text/platform/NativeStringDelegate.native.kt:17` · `toUpperCase`/`toLowerCase` use locale-independent stdlib casing; the `locale` param is ignored (wrong for Turkish dotted/dotless i, etc.). **Cosmetic.**
-- `compose/ui/ui/src/nativeMain/.../text/intl/Locale.native.kt` · `Locale.isRtl()` not implemented; the pipeline is LTR-only (`SdlParagraph.native.kt` `getBidiRunDirection` always returns `Ltr`; owners/DrawScopes default `LayoutDirection.Ltr`). No RTL shaping. **Nice-to-have.**
-- No `NumberFormat` / currency / decimal-grouping actual exists; numbers render via `toString()` with `.` decimal and no grouping regardless of locale. **Cosmetic.**
-
-## D. Font resolution
-
-**Custom fonts via compose-resources work.** `org.jetbrains.compose.resources.Font(Res.font.x)`
-loads the bytes and registers them with the project font registry (IconFont → NamedFont),
-so the standard CMP way to bundle a font renders correctly.
-
-- `FontFamily.Serif` / `FontFamily.Cursive` still collapse to the default sans — no bundled
-  serif/cursive font yet (`downloadNotoFonts` fetches Sans + SansMono only). Register one under
-  `generic:serif` / `generic:cursive` the same way to enable them. **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../text/font/FontFamilyResolver.native.kt:32` · `SdlPlatformFontLoader.loadBlocking`/`awaitLoad` are NOP; the androidx `PlatformFontLoader` path (`ResourceFont` / `Font(bytes)` / `LoadedFontFamily`) doesn't load. Use the working compose-resources `Font()` instead. **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../text/font/FontFamilyResolver.native.kt:38` · `PlatformFontFamilyTypefaceAdapter.resolve` returns `TypefaceResult.Immutable(Unit)` (the renderer resolves by name, so harmless). **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../text/font/FontFamilyResolver.native.kt:69` · deprecated `createFontFamilyResolver(fontResourceLoader)` ignores the supplied loader. **Cosmetic.**
-
-## E. Text rendering details
-
-- `compose/ui/ui/src/nativeMain/.../text/SdlParagraph.native.kt:376` · `drawNativeText` accepts and ignores text `Shadow`, stroke `DrawStyle`, and non-`SrcOver` blend, so those never render on text. **Cosmetic.**
-- `compose/foundation/.../text/StringHelpers.native.kt:31` and `compose/ui/ui/src/nativeMain/.../text/CharHelpers.native.kt:14` · `findPrecedingBreak`/`findFollowingBreak` (and `offsetByCodePoints`) do a codepoint/surrogate walk only, with no ICU grapheme clusters, so caret movement and backspace split combining marks and emoji ZWJ sequences. **Nice-to-have.**
-
-## F. Drag and drop
-
-Drop INTO the window (files + text) is fully wired and works. Drag OUT does not.
-
-- `compose/ui/ui/src/nativeMain/.../draganddrop/Sdl3DragAndDropOwner.kt:38` · `requestDragAndDropTransfer` is a NOP and `isRequestDragAndDropTransferRequired` returns `false`; `Modifier.dragAndDropSource` compiles but no OS-level drag leaves the window. Needs per-OS native work (NSDraggingSession / DoDragDrop / XDND); SDL3 has no portable start-drag. **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../draganddrop/Sdl3DragAndDropOwner.kt:119` · incoming transfer carries only file paths + a text blob; no image/URL/custom-MIME payloads. **Cosmetic.**
-- `compose/foundation/.../draganddrop/DragAndDropSource.native.kt:36` · no drag-shadow / drag-image feedback for internal DnD (upstream skiko renders one). **Cosmetic.**
-
-## G. Window and platform info
-
-- Multi-monitor: no display enumeration or per-monitor placement anywhere (`SDL_GetDisplays`/`SDL_GetDisplayBounds`/`SDL_GetDisplayForWindow` unused). **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../platform/PrefetchLocals.native.kt:18` · `LocalPlatformPrefetchScheduler` default is a NOP scheduler; lazy lists skip ahead-of-time item composition (correctness fine, possible scroll-in jank). **Nice-to-have (perf).**
-- `compose/ui/ui/src/nativeMain/.../node/impl/ComposeOwner.kt:324` · `autofill`/`autofillManager` are null; `requestAutofill` NOP. **Nice-to-have.**
-- `compose/ui/ui/src/nativeMain/.../node/impl/ComposeOwner.kt:279` · `hapticFeedBack.performHapticFeedback` NOP (no desktop pointer haptics API). **Cosmetic.**
-- `compose/ui/ui/src/nativeMain/.../node/impl/ComposeOwner.kt:287` · deprecated `clipboardManager` `setText`/`getText` NOP, and `clipboard.getClipEntry` null. Harmless: the real `LocalClipboard` (text + PNG image via SDL3) works. **Cosmetic.**
-- `compose/foundation/.../text/input/internal/selection/TextFieldSelectionState.native.kt:44` · `ClipboardPasteState.hasClip` aliased to `hasText`, so image-only clipboard is not detected for the paste affordance. **Cosmetic.**
-
-## H. Skia renderer anomalies
-
-Skia is the renderer everywhere, so its bugs are rarely tracked here. This one
-surfaced while adding BlendMode coverage (`demo --blendtest`):
-
-- `BlendMode.Multiply` renders wrong. A filled `drawRect` with opaque
-  `Color.Cyan` over opaque `Color.Yellow` reads back `(0,0,255)` blue; the
-  multiply formula can only yield `(0,255,0)` green for opaque cyan×yellow.
-  `Plus` and `Modulate` composite correctly on the same path, so
-  `paint.blendMode` IS applied — the fault is specific to `MULTIPLY` (likely a
-  Metal-backend / premultiply interaction in the graphics-layer flatten, not
-  the `BlendMode.toSkia()` map, which is correct). Needs isolating on the Skia
-  draw path. **Nice-to-have.**
-
-## J. Needs further review (2026-07 bug audit)
-
-An audit (parallel passes over the renderer and the text/input/event actuals)
-surfaced these. The clear, contained bugs were fixed in the same pass; the items
-here are left open because they are either invasive, risky, or a judgement call.
-(The renderer-side fixes from that pass predate the single-Skia consolidation and
-are no longer tracked here.)
-
-Fixed in the audit (for reference, not open work): `Locale.region` no longer
-returns the language for a single-subtag tag; and a `MOUSE_LEAVE` now clears
-hover so a widget doesn't stay highlighted after the cursor exits.
-
-Open — platform / input:
-
-- **Pointer coords are truncated to Int before DPR scaling** (`SDL3EventMapper.kt` ~78-97, `LegacyPointerEvent.kt` x/y are `Int`, consumed in `ComposeWindow.kt:756`). On a 2× display a click at logical (100.9, 50.4) becomes physical (200,100) instead of (~201,~100), so hit-testing / caret placement quantizes to 2-physical-px steps near glyph boundaries. Fix means widening the pointer event to `Float` through the pipeline — invasive, hence deferred. **Review.**
-- **A window created unfocused is still promoted to RESUMED** (`ComposeWindow.kt:575-576, 713-719`). `windowFocused`/`windowVisible` default `true`, so a second `Window {}` opened while another holds focus (or one opened minimized) reports `RESUMED` until SDL later delivers a focus/minimize event. Should query `SDL_GetWindowFlags` at creation. **Review.**
-- **IME text-input area is only pushed on the first `TEXT_EDITING`** (`ComposeWindow.kt:803`; `updateImeArea()` not called on focus gain / first `StartTextInput` / caret move). The first candidate popup can appear at (0,0) before correcting. The rect math itself is correct. **Review.**
-- **`Snapshot.sendApplyNotifications()` is called synchronously inside the global write observer** (`ComposeWindow.kt:143-146`). Compose Desktop's `GlobalSnapshotManager` deliberately defers it to a separate dispatch; calling it per-write is redundant (the main loop already calls it each frame) and risks re-entrancy during snapshot application. Verify against the runtime's guard before changing — behaviour-sensitive. **Review (risky).**
