Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: ⚪ Minimal · up to The PR is merge-ready after normal checks; the only remaining issue is a minor GC-root audit rationale naming the wrong resolver symbol, which affects maintenance accuracy only and has no user-facing or production impact.

at crates/perry-ext-events/src/lib.rs:1301-1306 and 1418-1424 so event-name
conversion occurs inside the js_async_hooks_provider_run_catching scope. Retain
and root the original event value in the call state, then resolve it in the
provider thunk before dispatch; preserve invalid-name handling and add parity
coverage for executionAsyncId() and AsyncLocalStorage.

Its GC roots are stack slots addressed via x19, and x19 is established as `mov x19, sp` immediately after the fixed prologue and before the dynamic `sub sp, sp, xN`, with no realignment — so x19 holds exactly the body SP the fp chain already reconstructs (`fp - fp_to_sp_offset`). Before this, any x19 root flipped the whole-image `chain_walkable` flag false (it required EVERY root to be fp/sp), which globally disabled the fast x29-chain root walk and forced every GC onto the platform unwinder. In cli.js just 63 of 72,812 functions use an x19 base, yet they disabled the correct fast walker for all of them; the unwinder then mis-resolved compiled-JS stack-slot roots and live young objects were swept (0xff-poison-receiver SIGSEGV / `(number).get is not a function`). Make `chain_walkable` accept x19 and resolve an x19 root like an SP root, gated per frame by `x19_is_body_sp` (confirms the `mov x19, sp` prologue shape); a frame that does not match still fails closed to the unwinder. Any other base register still disables the chain walk.
