Issues

• Release binaries are built before the version-bump commit: v3.12.0's tish reports 3.11.0 and pins tishlang_runtime 3.11.0

• AOT rust-native backend diverges on reassigned captured params — stale by-value reads, closure writes fail to compile

• Memory-issue audit: unbounded growth across shape registry, JIT, runtime streams and sessions (tracking)

• No cycle collector, and the VM mints a per-call-frame scope↔closure cycle for any body-level named function

• [native/gba] #682 residual: top-level statement temporaries still scale run()'s frame — statics engaged (615) yet a real game holds 20.5 KB; pre-#682 emission = 29.9 KB

• [native] possible #484 follow-up: "expected number" abort in large httpServe handler after await fetch (dune-server Hypery /oauth/token)

• [native/gba] A void-returning fn can never be promoted: fn_sig_all_i32 demands : i32 in the return, so 107 of 256 fns in a real game stay boxed

• [native/gba] E0425: a boxed closure cannot WRITE an outer module 'export let' — the cell is not captured for assignments

• [native/gba] #655 guard trip is uncatchable at typed call sites: 'expected number' panic fires before the pending RangeError is checked

• [native/gba] readonly (#672) is unusable on array natives: declaring one forces typed-extern dispatch, which an i32[] parameter cannot satisfy

• [native/gba] #663 follow-up: an array forwarded to a cargo: native is still boxed — let a declare fn assert its parameter is read-only

• [native/gba] Passing a typed module array to a native de-optimises EVERY read of it (3.8x), not just the call site

• tish build --target js emits a duplicate top-level alias when an exported name is also defined locally in another module
