The preview JPEGs (~2.4 MiB, already compressed so gzip passed them
straight through) leave the wasm data segment: a platform-free asset
registry in op-editor-core tracks per-route Absent/Pending/Ready/Failed
with single-flight and install-once semantics, the browser half fetches
over ArrayBuffer XHR with managed-mode headers and a slot-wrapped
callback so no synchronous failure can strand a route in Pending, and
paint sites fall back to the existing placeholder when bytes are not
(yet) there. Native keeps include_bytes verbatim. The staging script
copies the asset dirs into pkg/assets/ — under /pkg/ because the hub
frontend owns /assets/ — and the gate, CI workflow, and web image all
run it and assert the layout. Bundle: 7.13 → 5.10 MiB gzip, so the
tripwire returns to 6 MiB (85% occupancy); the sdk bundle keeps its own
8 MiB pending a real measurement.
Also closes the final review test gaps: the owner-session fixture now
returns a must-use lane guard (a dropped receiver made the saturated
lane read as Disconnected, not Full) and seeds the daemon's baseline
document so the hash check exercises the real path, and the closed
write barrier has a direct multi-page active-page regression test.
The idle-heartbeat test failed deterministically on linux (not the
timing flake it was first read as): TCP_KEEPIDLE/TCP_KEEPINTVL have
whole-second granularity there, so the test config's 50ms heartbeat
truncated to zero and setsockopt returned EINVAL on both ends of the
handshake — a real runtime bug for any sub-second heartbeat config,
fixed by clamping only the kernel keepalive cadence to >= 1s.
The 6 MiB gzip tripwire was set when the bundle measured ~4.5 MiB;
feature growth since (collab, prompt center, templates) added ~4.5 MiB
of embedded product assets, ~2 MiB of it pre-compressed JPEG that gzip
passes through. Reset the tripwire to 8 MiB and document that it is a
regression guard, not a budget, with the asset-split TODO that brings
the bundle back down.
47 commits from the align branch merged onto the force-updated remote
base (which had replayed an earlier snapshot of the same work plus new
overlay/pointer features and CI fixes). Conflict resolution: kept the
newer align side for the generation pipeline (orchestrator, mcp, skills,
design tools), kept the base side for the chat-panel test semantics and
graceful overlay teardown, fused both in sub_agent_session (design-turn
thinking policy + graceful epoch finish), and dropped the files each
side had deleted (legacy concurrent/dashboard paths, retired TS skills).
Deduped two identical replayed hunks (export.rs, chat_session_tests.rs).
Known issue carried over: provider_probe_host::landed_connected_outcome_
without_models_is_failure fails on a host with a live provider config
(env-sensitive test, both sides byte-identical there; green on CI).
Built-in design generation now runs as an agentic MCP tool-loop (reusing the
agent-rs BuiltInProvider), gated behind OPENPENCIL_DESIGN_AGENT_LOOP / the
Settings experimental toggle; the orchestrator stays the default.
- design-agent system prompt + in-process design toolset (parity-locked with
the MCP surface) + flag-gated Intent::Design routing
- spawn_agents execution as sequential sub-loops + live creation-mode badges
(per-agent glow + 'N/M designing...' header)
- new MCP tools: get_guidelines, ToolSearch, get_screenshot, get_editor_state,
export_nodes, spawn_agents; style-guide local audit
- #27 AI panel restyle: rounded tool cards + green check-rings, gray user
bubbles, model-pill bottom toolbar, header, empty-state pills, the
PARALLEL AGENTS (agent_team_size) 1x-6x chip dropdown
- multi-chat tabs: ChatSessions model (Deref-to-active) + tab row UI
(switch / close / + / Cmd+T) with each run bound to its tab
Large checkpoint commit spanning the working tree (Rust shell crates).
The WASM bundle build (#56) and op-web-sdk bundle workflows install binaryen
via apt, which on the ubuntu runner is v108 (2022) — too old for rustc 1.94's
wasm feature set. It lacks the --enable-bulk-memory-opt flag (the original
'Unknown option' failure) AND cannot validate the memory.copy/fill opcodes
rustc now emits, so wasm-opt rejects the bundle with 'all used features should
be allowed'. Download a pinned binaryen version_123 release (matches the local
dev toolchain) and prepend it to PATH. Verified locally: the full
check-wasm-bundle.sh pipeline passes with binaryen 123 against a fresh
rustc-1.94 wasm build.
Plan 1 of the web embedding SDK (TS-retirement Phase 2): a wasm Viewer that
parses a .op document, renders it read-only via CanvasKit by reusing
op-editor-ui's canvas_viewport, supports pan/zoom navigation, exposes
read-only JSON snapshots, and exports SVG. Type-gen reuses jian-ops-schema's
ts-rs export.
Additive: new crate plus surgical cold pub exposures (CanvasViewport::from_scene
in op-editor-ui; pub mod canvaskit + pub init_backend in op-host-web). No TS
deleted. 17 tests; wasm 2.2 MiB gzip (0 env.* imports); clippy -D warnings clean.
