#10223	fix(gc): trace large arrays by allocation bounds	#10215
#10234	fix(ui): macOS button and label padding	#10159
#10235	fix: preserve loop lexical TDZ and retained closure cells	#10051

#10239	fix: resolve awaited Worker path helpers and return unions	#10236
#10240	fix(macos): emit app bundles for local UI builds	#10078

Train commit:

• fix(compile): fix(macos): emit app bundles for local UI builds #10240's emit_sandbox_sidecar takes exe_path but only the macOS arm uses it, so its PR CI failed -D warnings (cargo check -p perry --bins) on Linux with unused variable: exe_path. The non-macOS arm now consumes it.

Validation (macOS, release, one target pool; per-PR CI attributed for the full gap/gc-stress/cargo-test tiers):

• Per-PR CI vs main's baseline logs: identical failing steps/tests/gap sets for every PR, except fix(macos): emit app bundles for local UI builds #10240's Linux warning (fixed above) and a SIGSEGV in its debug perry-runtime --lib run — fix(macos): emit app bundles for local UI builds #10240 changes no runtime code, and the local runtime suite is clean. fix(http): preserve listen arguments in dynamic server dispatch #10238's run turns test_gap_gc_http2_pending_event_callback_rooting green.
• scripts/run_lint_gates.sh: 80/83, the same three steps that fail on main. Raw-handle (bare + --no-raise-vs), runtime-root holders (full + self-test), shape census, store-site inventory, test registration pass; check_thread_locals.py reports only main's regex/perex_owner.rs.
• cargo test --release: perry-codegen 2031 passed; perry-hir pass; perry-runtime 3796 passed + main's release-only heap_generation::a_free_or_move_outside_every_scope_is_caught_in_debug_builds (includes the new large_array_slots and restore_coverage tests); perry-ext-http 89 passed; perry --bin perry 1113 passed; perry-ui-macos incl. native_widget_padding.
• Integration: loop_lexical_tdz, issue_10236_worker_path_await_helper, issue_9744_static_worker_helpers, issue_6185_thread_worker_closure_guards, issue_worker_threads_cross_thread_delivery, macos_app_bundle; scripts/test-loop-lexical-tdz.mjs oracle pass.
• Root dominance (shadow lowering corpus, CI flags incl. --seeded-violations 40 and --unrooted-allocas): pass.
• Gap filters tdz, lexical, loop, closure: pass.

📝 Walkthrough

Walkthrough

The pull request updates worker resolution, lexical TDZ allocation, HTTP listen parsing, garbage-collection tracing diagnostics, macOS application bundles, native widget padding, release metadata, documentation, and regression coverage.

Changes

Worker path resolution

Layer / File(s)	Summary
Worker helper analysis crates/perry-hir/src/dynamic_import/*	Worker helpers now support awaited values, conditional returns, URL candidates, and async functions while retaining validation limits.
Worker compilation and dispatch crates/perry/src/commands/compile/*, crates/perry-codegen/src/expr/*	Compilation resolves multiple worker candidates and generated code dispatches by runtime filename or URL.
Worker regression coverage crates/perry/tests/issue_10236_worker_path_await_helper.rs	Integration tests cover valid candidates, missing candidates, runtime selection, opaque calls, and recursion.

Lexical TDZ allocation

Layer / File(s)	Summary
TDZ lowering and code generation crates/perry-hir/src/lower/*, crates/perry-codegen/src/stmt/*	Nested forward-captured bindings receive fresh block-entry cells, including switch, loop, hoisted-function, and copied finally paths.
TDZ regression coverage crates/perry-hir/tests/*, scripts/test-loop-lexical-tdz.mjs, test-files/*	Tests cover HIR allocation, retained closures, switch fallthrough, exceptions, GC modes, and optimization levels.

HTTP listen parsing

Layer / File(s)	Summary
Shared listen parsing and dispatch crates/perry-ext-http/src/server/*	HTTP, HTTPS, HTTP/2, and Bun server paths now share parsed listen values instead of fabricated managed-array storage. Tests cover borrowed values and shifted arrays.

Garbage collection

Layer / File(s)	Summary
Array tracing and restore diagnostics crates/perry-runtime/src/array/*, crates/perry-runtime/src/gc/*	Large-array tracing uses physical allocation bounds. Restore diagnostics now report separate input and traversal counters. Regression tests cover both paths.

macOS bundles and widgets

Layer / File(s)	Summary
Application bundles crates/perry/src/commands/compile/*, crates/perry/src/commands/run/*, crates/perry/src/commands/{attest.rs,sidecar.rs,sandbox_profile.rs}	macOS UI builds create signed .app bundles with resources, metadata, and external sidecars. perry run launches the bundle executable.
Native widget padding crates/perry-ui-macos/src/*, crates/perry-ui-macos/tests/*	Buttons, text labels, and attributed-text labels support native padding with intrinsic-size, rendering, and drag-and-drop tests.

Release and documentation updates

Layer / File(s)	Summary
Release metadata and documentation Cargo.toml, CLAUDE.md, .github/workflows/test.yml, docs/src/ui/*, changelog.d/*	The workspace version, CI checks, UI documentation, and changelog fragments were updated.
