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).

# tools/check-wasm-bundle.sh — Step 1b §6 + §7.1 local bundle gate.
|
|
#
|
|
# What this script enforces (matches the CanvasKit production bundle gate
|
|
# and the env.* import count guard):
|
|
# 1. Required local tools are available: cargo, wasm-bindgen, wasm-opt,
|
|
# node, and gzip. CanvasKit needs no EMSDK / skia-safe / libc shim.
|
|
# 2. cargo build → wasm-bindgen → wasm-opt -Oz pipeline produces the
|
|
# served crates/op-host-web/pkg/op_host_web_bg.wasm. `wasm-opt` is invoked
|
|
# with the core WebAssembly features emitted by current rustc.
|
|
# 3. Post-bindgen bundle has 0 env.* imports
|
|
# (i.e. all imports come from `./op_host_web_bg.js`,
|
|
# the wasm-bindgen JS shim). Any env.* import = LinkError at
|
|
# load time → regression → fail.
|
|
# 4. Post wasm-opt -Oz gzip size ≤ STEP1B_SHELL_WASM_GZIP_LIMIT_BYTES
|
|
# (default 6 291 456 bytes = 6 MiB for the full CanvasKit app logic).
|
|
#
|
|
# This script is the local counterpart to
|
|
# `.github/workflows/wasm-bundle-build.yml`; keep the two recipes aligned.
|
|
#
|
|
# Exit semantics:
|
|
# 0 all four checks PASS.
|
|
# 1 any check FAILED — message names which one.
|
|
# 2 prerequisite missing (cargo / wasm-bindgen / wasm-opt / node / gzip).
