Why: Codex stop-time review #3 flagged "Type 0 component handling is
incomplete". The earlier C1 fix (orchestrator-plan-classify helper +
isMobileFullScreen heuristic) covered the orchestrator path, but four
more places still bucketed narrow widths (≤480 / ≤500) as mobile and
mishandled component-shaped plans.
What:
- agent-tool-executor.ts: replace `width<=500 ? 375 : 1200` bucket on
setGenerationCanvasWidth with the inserted node's actual width — a
400-wide profile card now estimates text against 400, not 375.
- design-type-presets.ts: add 'component' to DesignType union with
width=400, height=0, and a single-section default. detectDesignType
matches "X card / X badge / X chip / ..." prompts BEFORE the mobile
/ dashboard check, so the parse-failure fallback returns a 400px
component instead of a 1200px landing-page for "design a profile
card". Disqualified when prompt also names a screen / page.
- orchestrator-prompt-optimizer.ts: 3 spots — platform selection now
uses preset.type==='mobile-screen' (component groups with webapp,
not mobile, since it has no status bar / bottom nav); compact
prompt rules and subtask hint get a component branch ("Use width=400
height=0, exactly 1 subtask, no chrome"); fallback height map gives
components a single 200px region instead of 800.
- orchestrator-planning.ts: buildFallbackHeights treats narrow +
auto-height plans as component-shape and emits 200px sections,
preventing the prior "812 / 1 = 812-tall card" output.
2 new tests pin: (a) "design a clean profile card" → 400×0 single
"Component" subtask with 200px region; (b) "design a card screen page"
must NOT shortcut to component (screen/page disqualifier holds).
The pre-commit hook runs `bun run format` (prettier via oxfmt) on
every staged commit; without a prettierignore entry the hook keeps
reformatting the upstream-original Cargo.toml / Cargo.toml.orig
files inside vendor/skia-safe-op/{skia-bindings,skia-safe}/ to use
2-space indent + flow-style author arrays — drift against the
crates.io tarball form that we want to preserve so the diff against
upstream rust-skia stays minimal and auditable.
Same treatment vendor/agent/ and vendor/jian/ already get.
Updates the rust-multiplatform + rust-release workflows for the
post-C-hard.2 reality where the wasm32-unknown-unknown bundle IS
runtime-loadable locally but the CI side still needs more
automation before it can publish a release artifact.
rust-multiplatform.yml:
- add `vendor/skia-safe-op/**` to push + pull_request path
filters so changes inside the fork actually trigger CI
- rename the wasm-web job → "wasm32-unknown-unknown / openpencil-
shell-web (compile guard)" to make explicit that this is the
--no-default-features --features web stub-mount baseline, not
the real render bundle
- drop the artifact upload from this job: the stub .wasm has no
skia and would mislead downstream consumers
rust-release.yml:
- delete the standalone `wasm` job for now and update the comment
to a DEFERRED block listing the 6 CI-side automation steps
still missing (brew emscripten install, EMSDK env var,
.wasm.a → .a symlink hack, wasm-bindgen + wasm-opt, browser
smoke). Re-add the job once the pipeline lands
- update the workflow header copy so it stops claiming to build
the WASM bundle alongside desktop binaries
- drop `wasm` from the release-draft `needs:` list
This is an explicit deferral, NOT a silent drop — every removed
piece is annotated with the work item it is waiting on.
Step 1b §3.2 P0.5B Run path, sub-phase C-hard CI follow-up.
Lights up the Phase A WebShell on the C-hard pipeline (vendor/skia-
safe-op + crates/wasm-libc-shim, wired in the previous two commits)
so `cargo build --target wasm32-unknown-unknown --features skia`
followed by `wasm-bindgen --target web` produces a browser-loadable
ES module with 0 env.* imports.
What's added:
- WebBackend (src/backend/mod.rs): impl RenderBackend over a
skia-safe raster N32_PREMUL surface; presents each frame to the
host <canvas> via image_snapshot → read_pixels → ImageData →
put_image_data. end_frame surfaces present errors via
last_present_error / take_present_error so a stale failure does
not leak into a subsequent successful frame
- skia_wasm.rs: thin make_raster_surface helper so swapping in a
GPU GrContext (Phase A round 2) is a self-contained change
- mount(canvas_id) entry: locates the host <canvas>, builds a
WebBackend, paints the Phase A red-rect demo synchronously,
propagates any present error as a JsValue exception
- smoke/step-1b.html: manual smoke harness that mounts the shell
and surfaces a structured diagnostic (with regression-mode
LinkError messaging + rebuild instructions) if loading fails
- extern crate wasm_libc_shim as _; in lib.rs to keep the shim's
no_mangle symbols from being dead-code-eliminated
- .gitignore for wasm-bindgen pkg/ output
Cargo.toml feature wiring:
- default = ["web"] keeps the kickoff §1.2 wasm32-clean compile
guard CI green (stub mount, no skia)
- skia = ["dep:skia-safe", "wasm-libc-shim"] opts into the real
WebBackend + raster paint loop; the shim dep is target-gated
so only wasm32-unknown-unknown actually pulls it in
- wasm-bindgen = "=0.2.117" pinned (last release that compiles
on Rust 1.85; bump alongside the toolchain in a future commit)
Verified end-to-end:
- `cargo build … --features skia --release` green
- `wasm-bindgen --target web` produces ../pkg/*.{js,_bg.wasm}
- WebAssembly.Module.imports() returns 22 imports, all from
./openpencil_shell_web_bg.js; 0 env.* imports
- post `wasm-opt -Oz`: 1542 KiB raw / 599 KiB gzip — within
spec §6 ceiling (≤ 1024 KiB gzip)
- the kickoff §1.2 wasm32-clean compile guard still passes
(`cargo check … --no-default-features --features web`)
Browser-side manual smoke (Phase E) is still TODO; the bundle is
structurally LinkError-free but a human still needs to confirm the
red rect actually paints in Safari / Chrome / Firefox before the
sub-phase can be marked complete.
Step 1b §3.2 P0.5B Run path, sub-phase C-hard.2.
Provides the libc / libcxx / libm symbols that the wasm32-unknown-
unknown skia static archive (built via vendor/skia-safe-op) imports
at link time but wasm-bindgen does not synthesize. With this crate
linked in, the post-bindgen bundle has 0 env.* imports and is
runtime-loadable as a vanilla browser ES module.
Categories implemented (~83 symbols, dedup against the actual
import list):
- allocator: malloc / free / calloc / realloc / malloc_usable_size
via dlmalloc-rs + a 16-byte size header per allocation so the
GlobalAlloc::dealloc layout contract is preserved on free and
realloc copies min(old_size, new_size) on grow
- libm: asinh / acosh / atanh / nextafterf / remainder via libm
- libc string: memchr / wmemchr / strcmp / strcpy / strtoull
hand-rolled byte-wise
- libc stdio: snprintf / vsnprintf / vfprintf as C-side variadic
stubs (stdio_stub.c, compiled by cc) that route into a Rust
extern wasm_libc_shim_stdio_panic before returning, so any
actual invocation surfaces a named panic via console_error_
panic_hook instead of a silent empty success
- libc misc: abort (panics with diagnostic) + __errno_location
(single-mut-static — single-threaded wasm only)
- C++ ABI: __cxa_atexit (no-op), __cxa_guard_acquire / release,
__cxa_pure_virtual (panics)
- operator new / delete: _Znwm / _Znam / _ZdlPv* / _ZdaPv*
forwarding to malloc / free; _Znwm(0) routes through
malloc(1) per C++ standard (operator new must return a
non-null pointer)
- threads: sem_init / sem_destroy / sem_post / sem_wait no-op
- libcxx string / locale / iostream / shared_weak_count /
to_string: ~23 panic stubs via the libcxx_stub! macro that
panic with the symbol name; these are linker-pulled by
templated code that the skia raster + custom_empty fontmgr
pipeline does not exercise at runtime, so a panic = regression
signal
Build-time gating:
- active only on wasm32-unknown-unknown via cfg(all(target_arch
= "wasm32", target_os = "unknown")); native builds link an
empty crate so the symbols do not collide with the host libc
- compile_error! on target_feature = "atomics" because the
static-mut errno + non-atomic __cxa guard impls would race
under wasm threads — the path forward is real TLS errno +
atomic guard variables in a follow-up sub-phase
Step 1b §3.2 P0.5B Run path, sub-phase C-hard.2.
Wires the workspace at vendor/skia-safe-op (committed in the previous
commit) via [patch.crates-io] so every consumer of skia-safe /
skia-bindings — both the wasm32-unknown-unknown shell-web bundle and
the macOS / Linux / Windows shell-native desktop binary — resolves
through the fork on every target.
[patch.crates-io] is workspace-global, NOT target-scoped; cargo does
not natively support per-target patches, so this is the accepted
blast radius. The fork is byte-identical to upstream rust-skia 0.97.0
except for the new `wasm_unknown` platform module + its single new
dispatch arm; native builds resolve to the same upstream platform
modules they did before. Verified `cargo check -p
openpencil-shell-native` builds through the fork unchanged.
Trade-off: upstream rust-skia patches no longer flow until we
re-vendor; Cargo.lock records `path` sources for skia-bindings /
skia-safe rather than `registry+...`. The full rationale block is
inline in Cargo.toml.
The Cargo.lock delta also pins js-sys 0.3.97 → 0.3.94 / web-sys
0.3.97 → 0.3.94 — this is the transitive consequence of pinning
wasm-bindgen = "=0.2.117" on shell-web (last 0.2.x release that
compiles on the workspace's Rust 1.85 toolchain; 0.2.120+ requires
1.86). Documented in shell-web/Cargo.toml.
Step 1b §3.2 P0.5B Run path, sub-phase C-hard.1.
Vendors rust-skia 0.97.0 (from crates.io tarballs) into
vendor/skia-safe-op/{skia-bindings,skia-safe} and adds a single new
platform module — build_support/platform/wasm_unknown.rs — that
recompiles Skia C++ directly into the wasm32-unknown-unknown ABI:
- reuses emsdk's libc / libcxx headers via -isystem
- drops C++ exceptions + RTTI (-fno-exceptions -fno-rtti) so the
resulting .o files do not import emscripten's exception runtime
- forces clang's target via --target=wasm32-unknown-unknown
- sets CC_/CXX_/AR_wasm32_unknown_unknown so the cc-crate FFI shim
also picks up emsdk's bundled clang (host clang lacks wasm32)
- on every gn_args invocation overwrites skia/bin/activate-emsdk
with a no-op python stub so Skia's GN does not try to bootstrap
a parallel emsdk install (we use emsdk's clang directly)
Why a fork: wasm-bindgen --target=web on wasm32-unknown-emscripten
emits emscripten library glue, not a browser-loadable ES module,
which is incompatible with our distribution model. Compiling Skia
to wasm32-unknown-unknown unblocks the browser ES module path; the
remaining libc/libcxx/libm gap is filled by crates/wasm-libc-shim
in a follow-up commit.
The Skia C++ source tree under skia-bindings/skia/ (~770 MB, 30k+
files) is gitignored — it is fetched at build time by
binary_cache::download. Only the Rust source from the upstream
0.97.0 crate tarballs and the new wasm_unknown platform module are
committed here.
Step 1b §3.2 P0.5B Run path, sub-phase C-hard.1.
Codex P0 mini-gate Round 3 BLOCK fix: P0.2 plan calls for
tools/fetch-skia-artifact.sh, and Phase A CI step invokes it before
measuring bundle size — but the script did not exist in the OP repo.
Phase A cannot start without it.
Variant A (GitHub release asset) selected per probe notes §3.1
"Artifact Distribution Strategy": <1 MB gzip, free hosting, no extra
git-lfs setup overhead.
Behavior:
exit 0 artifact present and SHA matches OR no release pinned yet
(Phase E will publish; dev loop uses skia-bindings from-source)
exit 1 artifact present but SHA mismatched, or fetch failed after
a download attempt
Phase E will overwrite RELEASE_TAG / RELEASE_FILE / EXPECTED_SHA256
constants with the published release asset metadata. Until then dev
builds run skia-bindings from source (no fetch needed).
Smoke run: `bash tools/fetch-skia-artifact.sh` →
"no release tag pinned yet — Phase E will publish; dev builds use
skia-bindings from-source path" + exit 0.
Codex P0 mini-gate Round 2 finding (Q5) fix: gesture_re_export.rs tests
set the new W3C fields (KeyEvent.is_composing, FocusEvent.related_node_
id_hint, WheelEvent.delta_z + WheelEvent.mode mutability) but only
asserted the structural compile-time identity, not value readback.
Strengthened to assert every W3C field reads back what was written so
cross-crate type identity AND field-level binary compat are both verified
through the OP re-export path:
- key_event_is_re_exported_from_jian_with_all_w3c_fields: 7-field assert
- focus_event_is_re_exported_from_jian_with_all_w3c_fields: 3-field assert
- wheel_event_is_re_exported_from_jian_with_w3c_fields: defaults +
mutate-and-assert mode + delta_z + delta.x/y
cargo test -p openpencil-shell-core --test gesture_re_export → 6/6 PASS.
Why: MiniMax-M2.7 keeps emitting path nodes named "Search Icon Path" /
"Time Icon Path" / "Heart Icon Stroke" (3 words ending in noise word).
The legacy resolver normalised to "searchiconpath" (15 chars), prefix
fallback found "search" (6/15 = 40% < 50% threshold) → rejected →
fallback to lucide:circle → user-visible "circle bug" across categories,
filter chips, and search bar leading icons. Skill update alone (telling
models to use icon_font) doesn't fix the trained-pattern leftover —
Codex flagged this as a still-unfixed failure mode.
What: extractIconKeyword() tokenises on camelCase / space / dash /
underscore boundaries and drops { icon, logo, symbol, glyph, path,
shape, stroke, fill, svg, graphic, image }. Surviving tokens are
concatenated for direct dictionary lookup. Pure-noise names ("Icon
Path", "Symbol") return early without writing the misleading circle
placeholder. time / deliverytime / rider aliases added (kept in sync
across icon-dictionary.ts and server icon.ts NAME_ALIASES per existing
comment). 11 new tests cover multi-word resolution and pure-noise
no-op; 21 prior regression cases (descriptive geometry untouched,
single-word camelCase / kebab / snake all resolve, "Brand Logo"
placeholder behaviour preserved) still green.
Why: MiniMax-M2.7 food-app run rendered Header with white fill on cream
page bg, and used iconFontName=shopping-bag for Cart tab. Two skill-side
issues: icon-catalog.md was self-contradictory ("use path nodes" vs
"use icon_font"), and layout.md had no rule for inner-section bg.
What:
- icon-catalog.md rewritten as "ALWAYS USE icon_font, NEVER path NODES"
with role→name map (Cart→shopping-cart not shopping-bag, Pizza→pizza,
Sushi→fish via alias, etc) and food-category icon list appended.
- layout.md adds: interior section wrappers (Header, Search Section,
Categories Section) MUST have fill:[] (transparent / inherit page bg);
only opt into a fill when the section is intentionally a card with
its own surface tone.
Why: "Design a profile card" through MiniMax-M2.7 produced a 375×803 mobile
screen with auto-injected status bar, because the planner skill listed
"profiles" as a Type 2 single-task screen and the orchestrator's
isMobileScreen heuristic ran on width≤480 alone.
What: design-type.md + decomposition.md add Type 0 (single component:
card / badge / chip / modal) with width=400 height=0 1 subtask no chrome.
isMobileFullScreen helper extracted to orchestrator-plan-classify.ts and
required by both orchestrator.ts and orchestrator-sub-agent.ts so the
two paths can't drift on what "mobile" means (Codex review caught this
when only orchestrator.ts had the new check).
Verified with same MiniMax + same prompt: 400×320 component, 8 nodes,
firstChildRole=card, no status-bar.
The merge of origin/v0.8.0 brought in Kayshen's 504f1874 / ef4f9f67
which delete src/event.rs + src/event/mod.rs (re-affirming v19.4 drop).
Local 6af3a7d7 had wired `pub mod event` into both shell-core and
shell-native lib.rs to keep those files alive — now the source files
are gone and the `pub mod event` declarations point at nothing.
Drop the dangling declarations:
- crates/openpencil-shell-core/src/lib.rs: remove `pub mod event;`
- crates/openpencil-shell-native/src/lib.rs: remove `pub mod event;`
+ the `pub use event::JianPointerMapper;` re-export
Verify: cargo check --workspace --tests + cargo test -p shell-core
-p shell-native both green; format:check + tsc + vitest 4223/4223 pass.
This finalizes the same direction Kayshen's commit message describes
("shell-core exposes Jian gesture types directly without an OP-side
wrapper") — confirmed with user before merging.
Step 1a v19.4 commit f9dd4b56 deleted ShellEvent + JianPointerMapper, but
the merge in 46f77eab (cf61bcc1 ↔ origin/v0.8.0) inadvertently re-added
src/event/mod.rs and tests/event_mapping.rs from the inbound side.
src/event/mod.rs is dead source — lib.rs no longer declares
`pub mod event` and no consumer imports JianPointerMapper. The test file
imports a symbol lib.rs no longer re-exports, so
`cargo test -p openpencil-shell-native --no-run` fails compile.
Step 1b Phase 0 must start from a green baseline; deleting both files
restores it.
cargo test -p openpencil-shell-native --no-run → all integration tests
compile clean.
Picks up the keyboard/IME/focus event additions + W3C wheel deltaMode
landed in jian commit d5d358e. shell-core re-exports of the new types
land in the next commit; this commit only moves the pointer + Cargo.lock.
cargo test -p openpencil-shell-core --test gesture_re_export → 6/6 PASS
against the pinned submodule.
ab-corpus rerun (gpt-5.5, ab-v3, 52 prompts × 2 arms): obvious-T M3
59.6% -> 91.5% (+31.9pp); composite-T 0% -> 40% (+40pp). Lift on top
of d5d1a8cd (Rank 1 schema coerce), 9e90cffe (Rank 2 prompt fail watch),
e34d9238 (Rank 3 vision toggle).
Builder fallback minima:
- chart-pie/line/bars-v1: values [1] -> [30,25,20,15,10] / [10,15,12,20,18]
so chart-pie-slice (>=4) and chart-line-dot (>=7) corpus minima are met
- toolbar-v1: fallback items include a divider_after entry so toolbar-divider
role emits even when the model passes only icons
- avatar-group-v1: entry-coerce items with 5 placeholder initials so the
builder always emits avatar-group-{item,initial,overflow,overflow-count}
- combobox/data-table-row/share-row-v1: fallback arrays grown to 3 items
matching the corpus shape minimums
Optional-content discipline (codex stop-time round 2):
- user-card-v1: name field fuzzy-coerce (required field, real fix for the
"Element tool insert failed: I(null,...)" handler bug); the optional role
text stays conditional, never invented. content empty-string was tried
but rejected (empty text nodes still consume flex gap).
- image-placeholder-v1: label stays conditional for the same reason.
Prompt:
- elements.md fail-watch table extended with 5 components (chart legend,
skeleton, inline-action, share-row, combobox) so models routing to
batch_design at least know the role names.
Multi-page vision validation (codex stop-time round 1):
- design-validation.ts: countNodesInActivePage + buildNodeTreeDump now
read getActivePageChildren(activePageId) instead of DEFAULT_FRAME_ID,
so the size-gate and the LLM's tree dump both reflect the page the user
is actually editing rather than the default page. Was a latent bug
surfaced when VALIDATION_ENABLED flipped to true in e34d9238.
Tests: 4223/4223 pass; format:check + tsc clean. 12 files changed.
Toggle VALIDATION_ENABLED from false to true so the post-generation
vision LLM validation loop runs. The loop itself was fully built in
design-validation.ts long ago — only ai-runtime-config:109 was holding
it at runtime.
Add VALIDATION_NODE_COUNT_THRESHOLD=30 size-gate so atomic single-tool
outputs (one badge, one chart) skip the +30-90s vision round-trip.
Composite multi-section briefs (full-page mockups, dashboards) easily
clear the threshold and benefit from the screenshot -> vision LLM ->
safe-fix -> re-screenshot rounds.
Pre-validation heuristics (ms-cheap tree walks) still run regardless
of size.
Plumbing was already done before this commit:
- design-screenshot.ts captureRegion() shipped in Phase 1.5
- design-validation.ts MAX_VALIDATION_ROUNDS=3 loop fully implemented
- validate.ts has 4 vision provider paths (Anthropic Agent SDK,
Codex CLI, OpenCode SDK, Gemini CLI)
This commit only flips the flag and adds the size-gate heuristic.
Tests: 4223/4223 pass; format:check + tsc clean.
Predicted KPI lift: M3 composite +5-10pp (speculative). Vision
catches what schema-coerce + role-hint can't — mis-positioned sibling
sections, missing component spacing, color-contrast issues. Gating by
node count keeps user-perceived latency contained to designs that
actually need it.
Out-of-scope for this commit (followups if needed):
- ab-corpus glm/minimax/deepseek client image_url part injection
(lets the eval harness exercise vision for KPI verification)
- builtin Zig agent-native runtime image part support (only matters
if the embedded provider becomes the default)
ab-v8 obvious-T 40 fails matched "missing required role(s)" — model
went batch_design fallback rather than the matching add_*_v1 tool, and
forgot the role names the validator checks. Surface the top 12
fail-mode component-to-tool mappings + their explicit role names at
the top of elements.md (was previously buried 400 lines down in the
keyword section).
Components covered: modal-shell, avatar-group, metric-comparison,
image-placeholder, tag, toolbar, callout, profile-header, inbox-message,
drawer-shell, cookie-banner, user-card.
Even if the model still insists on batch_design (no v1 fits), the
explicit role list helps it emit the correct role strings on each
child node.
Tests: 84/84 pen-ai-skills pass; format:check + tsc clean; skill
budget under 2400 tokens unchanged.
Predicted KPI lift: M3 obvious-T +3-5pp on top of Rank 1's +6pp.
Recovers ~1/3 of the 40 missing-role fails on stronger models
(deepseek/gpt-5.5); weaker models (kimi/minimax) still need the
vision-feedback loop in Rank 3.
The merge of origin/v0.8.0 (commit 19582fc) resurrected the 4 ShellEvent
files that b133ebc0 / f9dd4b56 declared dropped — the same modify-vs-delete
artifact 50c9c3de cleaned up after 6fbee16a. Per user direction keep the
files: declare the event modules in both lib.rs + re-export JianPointerMapper
at shell-native crate root so the existing tests resolve.
Tests: event_shape 3/3, event_mapping 15/15, workspace cargo check + test
green, format:check / tsc / vitest (4204) all pass.
Also ignore xhs-images/ + .baoyu-skills/ in .prettierignore (local tutorial
scratch dirs; oxfmt was scanning markdown inside).
Codex stop-hook caught README:505 still mentioned the v19.4-removed
ShellEvent + JianPointerMapper translation layer. Updated to reflect:
- shell-core re-exports jian_core::gesture::* directly (events consistent
with Jian per v19.4)
- spec v19.5 FROZEN
- full multi-OS CI matrix (now incl Windows aarch64 cross, macOS x86_64
cross from Apple Silicon, Linux aarch64 cross)
- OP visual model + chrome Rust-only constraint deferred to Step 1c+
spec §1.2 acceptance #7 calls for cargo build --examples --workspace 三 OS
PASS in CI. Previously cargo build --workspace + cargo clippy --all-targets
were considered equivalent (clippy with --all-targets compiles examples),
but Phase B+C Gate codex review CONCERN-C1 said the explicit step should
be in the workflow for unambiguous acceptance trace.
Adds cargo build --examples --workspace --target <target> --release
between cargo build --workspace and cargo test on host runners. Skipped on
cross-arch check_only matrix (cross examples build is out of scope; test
runners cover real arch builds).
Per user 2026-05-05 directive: OP render engine + event types stay
consistent with Jian. The OP-specific ShellEvent enum + JianPointerMapper
translation layer (Phase B Task 3 commit f2169d00) was over-designed —
OP-side abstraction provides no value over directly consuming
jian_core::gesture::PointerEvent.
Deleted:
- crates/openpencil-shell-core/src/event.rs (ShellEvent enum + 9 subtypes)
- crates/openpencil-shell-core/tests/event_shape.rs (3 unit tests)
- crates/openpencil-shell-native/src/event/mod.rs (JianPointerMapper)
- crates/openpencil-shell-native/tests/event_mapping.rs (15 unit tests)
Added:
- shell-core lib.rs re-exports jian_core::gesture::{PointerEvent,
PointerKind, PointerPhase, MouseButtons, Modifiers, PointerId} so
consumer code can import Jian event types via the OP shell crate.
OP visual model differentiation (single-page + infinite canvas
recommended, multi-page also supported, no routing, cross-page event
linkage when multi-page) lives at canvas viewport layer (Step 1c+),
not at event type abstraction.
spec v19.3 → v19.4 mini-patch (separate commit in openpencil-docs)
documents the simplification.
Phase B Task 3 implementation per spec v19 §5.1 + §5.1.1 (FROZEN
2026-05-04):
shell-core:
- New `event` module declaring `ShellEvent` (6 variants per spec §5.1)
+ sub-types `PointerId / TouchId / TouchPhase / TouchForce /
MouseButton / ElementState / ScrollDelta / Modifiers / KeyCode /
WindowEventKind`. Pure OP types — no winit / Jian / GL — so the
enum is wasm32-clean and visible on iOS / Android (spec §11.3).
- TouchForce::Calibrated mirrors winit::Force 1:1 (spec §11.3
invariant) so Step 1f mobile mapper compiles without API break.
- Newtype id fields are `pub` so shell-native can construct them across
crates (spec round 3 BLOCK-R3-4 fix).
shell-native:
- New `event` module (cfg-gated desktop only) housing
`JianPointerMapper` — stateful diff over the per-PointerId
`MouseButtons` snapshot. Diff runs on Down / Up / Move (spec round 3
CONCERN-R3-1 fix); Hover / Move emits a trailing `PointerMove`.
- Touch branch maps Down/Move/Up/Cancel → Started/Moved/Ended/Cancelled;
Touch Hover returns `Vec::new()` (touches never hover).
- Mouse / Pen / Stylus / Trackpad share the same diff branch.
- Degraded inputs (no button transition + no Move emission) return
`Vec::new()` instead of synthesising a `ShellEvent::Other` variant
(spec round 4 CONCERN-R4-1 fix; the enum stays at exactly 6 variants).
Tests:
- 15 new unit tests in shell-native/tests/event_mapping.rs covering
the 4 Touch phases, mouse Hover, LEFT Down/Up pair, multi-button
press/release during Move, Pen/Stylus/Trackpad routing, two
degraded-empty paths, and modifiers propagation (CMD → meta).
- 3 new shape tests in shell-core/tests/event_shape.rs proving the
6-variant invariant + TouchForce::Calibrated field shape +
`pub`-field newtype constructibility.
Verified:
- `cargo test -p openpencil-shell-core -p openpencil-shell-native`
green (36 tests total across both crates).
- `cargo check --target wasm32-unknown-unknown -p openpencil-shell-core`
green; shell-web on wasm32 still compiles with the new module pulled

Hosted Ubuntu runner has libegl1-mesa-dev installed but no X display, so
`eglInitialize` fails with 'EGL is not initialized, or could not be

xvfb gives EGL_DEFAULT_DISPLAY a real X11 connection so eglInitialize
succeeds; LIBGL_ALWAYS_SOFTWARE + llvmpipe + MESA_GL_VERSION_OVERRIDE
forces Mesa software pipe (no GPU on runner). Together these unblock
the EGL pbuffer GPU smoke + chrome+stub composition tests on Linux CI.
Spec v19 §11 invariant 1 requires shell-native to compile on iOS / Android
cargo check, with the `GlContextProvider` trait (invariant 2) importable on
every non-wasm target. Previously the desktop GL stack (glutin / winit /
skia-safe) was referenced unconditionally in src/, so mobile cargo check
broke the moment the Cargo.toml target-gated those deps to macOS / Linux /
Windows.
This change cfg-gates the desktop-only modules and items so the mobile
cargo check builds only the cross-platform surface:
- src/lib.rs: gate `backend` + `canvas_view_stub` modules and their
re-exports to desktop OS targets; add `EaglProvider` / `AndroidEglProvider`
re-exports under `target_os = "ios"` / `"android"`. `GlContextProvider`,
`ProviderError`, `ProviderResult` stay always-on (per §11 invariant 2).
- src/context/mod.rs: split into a cross-platform trait surface +
per-platform provider re-exports; gate `shared` (depends on `skia_safe` +
`winit`) to desktop only.
- src/context/provider.rs: cfg-gate `GlutinProvider` struct + impls + the
`pick_display_api` helper to desktop OS only; localize `CString` /
`NonZeroU32` imports inside fn bodies; gate `from_error` to desktop to
silence dead_code on mobile (the only caller is `GlutinProvider`).
- Cargo.toml: split deps into a cross-platform `cfg(not(wasm32))` block
(jian-core + glow + raw-window-handle, all required by the trait
signature on every non-wasm target) and a desktop-only block (skia-safe,
glutin, glutin-winit, winit, scopeguard, jian-skia, jian-host-desktop).
Merges the previously duplicate desktop `[target...]` table headers that
cargo rejected.
- ci: rust-multiplatform.yml mobile-check job now runs cargo check on
shell-native too (per the comment update there).

Codex flagged: when the convert pass runs BEFORE
normalizeTreeLayout (required to preserve child x/y offsets — see
2fa66bc1), accepting \`layout === undefined\` as a vertical signal
mis-classifies layout-less horizontal rows. A model that emits
two equal-height images side by side without an explicit \`layout\`
field intends a horizontal row; \`inferLayout\` (which normalize
later runs) often agrees. The earlier converter saw the absent
keyword as "vertical-shaped" and flipped the row to absolute,
collapsing both images to (0,0).
Tightened the gate to require explicit \`layout: 'vertical'\`. A
hero that omits the keyword is now an acceptable miss — the
convert pass leaves it for normalize to classify, after which
nothing else fires the layered-detection rule (normalize would
have stripped the children's x/y by then anyway, so even running
convert again post-normalize wouldn't help). The cost is a small
miss rate on extremely sloppy hero outputs; the benefit is no
false positives on legit horizontal rows.
New regression test: layout-less frame with two side-by-side
height-200 images stays untouched. Verified by reverting the
gate to also accept \`undefined\` — the new test correctly fails
("expected false to be true"). All 8 tests pass with the
tightened gate.
Codex flagged: \`normalizeTreeLayout\` strips \`x\` / \`y\` from
non-overlay children of any vertical / horizontal layout container
as a stale-coordinate cleanup. The new
\`convertStackedOverlayToAbsolute\` post-pass was wired in AFTER
normalize, so when a sub-agent emitted an intentional content
offset on a layered hero — e.g.
hero { layout: 'vertical', height: 200, children: [
image { full bg },
overlay { full bg gradient },
content { x: 16, y: 80 } ← inset above the gradient
]}
normalize would delete the \`x: 16, y: 80\` first, then convert
would flip layout to 'none' on a hero whose children have no
positions to honor. The content frame ends up at (0,0) overlapping
the bg image instead of where the model placed it.
Move convert to run BEFORE normalize. After convert, the
container's layout is 'none' so normalize sees an absolute-
positioning container and leaves the children's x/y untouched.
The function is a no-op when no layered pattern matches, so
running it earlier doesn't add cost on the common path.
New test asserts: convert + normalize (in that order) preserves
content's x=16, y=80 through the chain. Verified by reversing the
order in the test — assertion correctly fails with
"expected undefined to be 16", proving the regression coverage
actually exercises the bug condition.
M2.7 food-app run shipped a hero whose content piled into the next
section. Live doc inspection showed:
hero-image-container { width: 'fill_container', height: 200,
layout: 'vertical' }
├─ hero-image { width: 'fill_container', height: 200 }
├─ hero-overlay { width: 'fill_container', height: 200 } // gradient
└─ hero-content { width: 'fill_container', height: 'fit_content' }
├─ "Hungry?" title
└─ search-bar (48 tall)
The model intended the image + overlay to LAYER on top of each
other as bg+gradient with content floating on top. With
\`layout: 'vertical'\` the layout engine instead stacked them
sequentially: 200 + 200 + ~80 = 480, far past the 200 declared
height. No clipContent on the container, so the overflow rendered
into the NEXT sibling section — the user's screenshot showed
"Hungry?" search and category icons piled over the "Near You"
restaurant cards.
\`convertStackedOverlayToAbsolute\` post-pass detects the pattern
conservatively:
- frame, layout='vertical' (or undefined → infers vertical)
- numeric fixed height H
- >= 2 children of types image / rectangle / frame whose height
is exactly H or 'fill_container'
The repair: switch \`layout\` to 'none' so the layout engine
respects each child's own x/y (defaulting to 0/0 = layered) — the
image lands at (0,0), the overlay layers on top, and the content
frame floats on top. Children with explicit positions stay
respected.
Wired into \`design-canvas-ops.ts::applyPostStreamingTreeHeuristics\`
right after \`expandOverflowingFixedHeightCards\` so both layered
and overflowing-fixed-height fixes run together.
6 tests cover: hero pattern conversion, fill_container variant,
plain content stacks left alone (only one bg-like child), no
fixed height left alone, horizontal-layout side-by-side rows
left alone, nested heroes detected.
MiniMax M2.7 food-app run failed because the model emitted its full
subtask design wrapped in a single JSON array literal:
[
{ "id": "filterChips-root", "_parent": null, "type": "frame", … },
{ "id": "chip-1", "_parent": "filterChips-root", … },
…
]
The previous \`looksLikeJsonl\` gate only checked
\`startsWith('{')\` so this fell through to the DSL parser, which
tried to read \`[\` / \`{\` / \`}\` each on its own line as DSL
operations. Every line was rejected, the subtask returned empty,
the orchestrator retried with minimal skills, that timed out too,
and the user got a single-frame placeholder with one section
instead of the full screen.
Extended the gate to accept \`[\` as the leading character. The
shape signature stays the same (\`_parent\` or PenNode \`type\`
key inside the first 800 chars) — the bracket check just
disambiguates from real DSL. \`parseJsonlToTree\` already handles
both shapes via brace-counting (it scans for \`{...}\` blocks and
ignores surrounding \`[\`, \`]\`, and \`,\`), so the apply path
needed no changes.
Exported \`looksLikeJsonl\` for direct unit testing. 6 new tests
cover: pure JSONL match, JSON-array match (the M2.7 case),
array with leading whitespace, DSL-style assignment lines reject,
empty/non-bracketed reject, and bracketed-but-no-PenNode-keys
reject (so we don't reroute legit non-design array operations).
Verified by temporarily reverting the gate to just \`{\`: the two
new array tests correctly fail.
Phase B Task 3 implementation per spec v19 §5.1 + §5.1.1 (FROZEN
2026-05-04):
shell-core:
- New `event` module declaring `ShellEvent` (6 variants per spec §5.1)
+ sub-types `PointerId / TouchId / TouchPhase / TouchForce /
MouseButton / ElementState / ScrollDelta / Modifiers / KeyCode /
WindowEventKind`. Pure OP types — no winit / Jian / GL — so the
enum is wasm32-clean and visible on iOS / Android (spec §11.3).
- TouchForce::Calibrated mirrors winit::Force 1:1 (spec §11.3
invariant) so Step 1f mobile mapper compiles without API break.
- Newtype id fields are `pub` so shell-native can construct them across
crates (spec round 3 BLOCK-R3-4 fix).
shell-native:
- New `event` module (cfg-gated desktop only) housing
`JianPointerMapper` — stateful diff over the per-PointerId
`MouseButtons` snapshot. Diff runs on Down / Up / Move (spec round 3
CONCERN-R3-1 fix); Hover / Move emits a trailing `PointerMove`.
- Touch branch maps Down/Move/Up/Cancel → Started/Moved/Ended/Cancelled;
Touch Hover returns `Vec::new()` (touches never hover).
- Mouse / Pen / Stylus / Trackpad share the same diff branch.
- Degraded inputs (no button transition + no Move emission) return
`Vec::new()` instead of synthesising a `ShellEvent::Other` variant
(spec round 4 CONCERN-R4-1 fix; the enum stays at exactly 6 variants).
Tests:
- 15 new unit tests in shell-native/tests/event_mapping.rs covering
the 4 Touch phases, mouse Hover, LEFT Down/Up pair, multi-button
press/release during Move, Pen/Stylus/Trackpad routing, two
degraded-empty paths, and modifiers propagation (CMD → meta).
- 3 new shape tests in shell-core/tests/event_shape.rs proving the
6-variant invariant + TouchForce::Calibrated field shape +
`pub`-field newtype constructibility.
Verified:
- `cargo test -p openpencil-shell-core -p openpencil-shell-native`
green (36 tests total across both crates).
- `cargo check --target wasm32-unknown-unknown -p openpencil-shell-core`
green; shell-web on wasm32 still compiles with the new module pulled
through.
- `cargo check --target aarch64-apple-ios -p openpencil-shell-native`
