id: investigate: world-VM Wasm portability audit — what of the worlds runtime runs inside a Worker #2057
Description
Source: the Cloudflare Workers fit investigation (on #2044) open question 1. Audit pkgs/id's world execution (sandboxed Roc/Wasm programs in shared journaled worlds) against the Workers Wasm reality: Wasm supported (SIMD yes, threading NO, WASI experimental), 128 MB memory, CPU-time limits. Which world programs and VM features port to an isolate, which need a native-node fallback, and what the hosted edition may therefore promise app authors.
Program: Drew's 2026-10-28 directive (full text: hatch-personal memory/topics/id-program-2026-10-28.md). Parent epic: #2056.
Working pattern: parallel investigations, then the named synthesis issue merges them into a full design. Route guidance: Workhorse by default; Specialist/Summit for synthesis and ramification-heavy work. A result that says "done" is not the endpoint — the orchestrator reviews it and may commission another round. Deliverables: a markdown design/investigation doc (mermaid/SVG diagrams welcome) linked from this issue, plus follow-up issues for anything buildable. Build a proof of concept where the design calls for one, but do NOT build the permanent feature on top of an unreviewed PoC.
Acceptance criteria
- A written portability audit exists mapping pkgs/id world-VM features against Workers Wasm limits (no threading, WASI experimental, 128 MB, CPU-time caps)
- Each world program/feature is classified: ports to an isolate, needs native-node fallback, or is excluded from the hosted edition's promises
- The resulting promise list for app authors is stated explicitly

Intake review
Part of the ID platform expansion program (parent epic #2056; source: the Cloudflare Workers fit investigation on #2044, open question 1). Filed by Drew 2026-10-28; not resolved by any merged PR. Suggested approach: audit the worlds runtime feature-by-feature against the documented Workers limits in the issue body and record the classification on this issue. Risk: an un-audited feature silently becoming a hosted-edition promise.

Top priority — ID program wave-1. Drew directed this be picked up in the next runs (2026-10-29): enqueued directly as triage task 3359 in repo-health-code-pilot at queue priority 20 (only breakage-class work at priority 10 outranks it). Wave-1 is the ungated investigations and designs; syntheses and PoCs stay gated on their named inputs. Investigation route: Workhorse.

Queued: repo-health-code-pilot task 3927 (2026-10-30), wave-2 follow-on. The 2026-10-29 triage verified this issue and recorded 'write the investigation' as the next step; this task is that write — investigation doc PR under doc/, follow-up issues for buildable pieces, close with the doc link. Ordered by Drew ('queue unrun').

Investigation write — world-VM Wasm portability (#2057)
Task 3359's 2026-10-29 audit is now the wave-pattern doc at
doc/2026-10-30T19-36-00Z_investigation_world_vm_wasm_portability/(PR #2817, merged), re-verified against current main: fuel/memory/manifest machinery and example worlds confirmed; #2271 and #2046 open as scoped. One drift corrected: the tree pinswasmtime = "=48.0.7", not 43 — the host-replaceable framing is unaffected.PoC #2271 remains the only open buildable from this issue; nothing new filed.
