Combined replacement for the two split Dependabot PRs (#1, #2). The crates re-export types from each other and must move in lockstep; bumping only one produces 'mismatched types' between wasmtime::Error and wasmtime_internal_core::error::error::Error. Source changes required by v45: - wasmtime::Error no longer implements std::error::Error, so the anyhow::Context trait no longer applies to Result<_, wasmtime::Error>. Switch to wasmtime's own error::Context trait, which provides the same .context() method on those Results. - Config::async_support is deprecated and a no-op in v45 (async support is always enabled when the component-model feature is on). Drop the call.

The shipped wit/nexum-runtime/identity.wit defines sign() as
personal_sign — host MUST prepend the EIP-191 prefix
('\x19Ethereum Signed Message:\n<len>') before hashing. docs/01
described it as 'sign raw bytes' which is a transaction-signing
footgun (a raw signer can be tricked into signing EIP-155 / EIP-712
payloads disguised as plain bytes) AND diverges from the WIT — two
compliant hosts implementing different specs produce mutually
unverifiable signatures.
Align docs/01 to the WIT. Note that raw-bytes signing, gated by an
explicit capability, is on the 0.3 roadmap.
Resolves PR #6 finding #1.

…lities) (#6) * docs: add 0.1 to 0.2 migration guide * wit: rename web3:runtime to nexum:runtime, unify error model, add identity/clock/random/http/query-module * chore: rename crate nxm-engine to nexum-engine; bump to 0.2.0 * build: update justfile and CI for nexum-runtime + nexum-engine rename * docs: rename to nexum:runtime, unify error model, mark non-server platforms as planned * runtime: update engine + example to 0.2 WIT - Engine main.rs targets world `shepherd` (formerly `shepherd-module`), generates against nexum:runtime@0.2.0 + shepherd:cow@0.2.0. - Replaces per-domain error records (JsonRpcError, MsgError, StoreError, ApiError, bare String) with unified HostError + HostErrorKind across every host impl. - Adds Identity host stub (was missing in 0.1 despite being doc'd). - Adds chain::request_batch stub that falls back to per-call dispatch. - Renames feed_get/feed_set -> read_feed/write_feed. - Drops separate cow + order interfaces, replaced by single cow_api with request and submit_order. - Block ts in test event is now ms (1_700_000_000_000) per types.wit documented unit. - Example module targets event-module world, matches Event::Tick instead of Event::Timer, returns HostError from init/on_event. * example: drop empty-name guard from init The guard was inconsistent: missing 'name' key silently defaulted to 'unknown' and returned Ok, but an explicit empty string returned Err — and both paths logged a success-shaped 'name=...' line BEFORE the guard ran. The example is a hello-world; a config-validation guard belongs in a real module, not a starter. Drop it. Resolves PR #6 finding #9. * ci: add wit deps sync check Both wit/nexum-runtime/ and wit/shepherd-cow/deps/nexum-runtime/ are committed to the tree; the latter is regenerated by 'just sync-wit'. Without a CI guard, a contributor can edit one without the other and the divergence only surfaces at runtime (interface-mismatch on module instantiation) — not at build time. The new job re-runs the same copy that 'just sync-wit' does, then fails if the deps tree differs from the freshly-copied canonical. Resolves PR #6 finding #8. * docs/01: align identity::sign to personal_sign semantics The shipped wit/nexum-runtime/identity.wit defines sign() as personal_sign — host MUST prepend the EIP-191 prefix ('\x19Ethereum Signed Message:\n<len>') before hashing. docs/01 described it as 'sign raw bytes' which is a transaction-signing footgun (a raw signer can be tricked into signing EIP-155 / EIP-712 payloads disguised as plain bytes) AND diverges from the WIT — two compliant hosts implementing different specs produce mutually unverifiable signatures. Align docs/01 to the WIT. Note that raw-bytes signing, gated by an explicit capability, is on the 0.3 roadmap. Resolves PR #6 finding #1. * docs: align chain::request-batch and http WIT snippets to shipped types Both snippets in the migration guide and docs/01 showed list<tuple<string, string>> shapes that don't match the shipped WIT. Adopters who copy the doc snippets get wit-bindgen type errors against the real interfaces. - chain::request-batch now uses the nominal record rpc-request and variant rpc-result (matching wit/nexum-runtime/chain.wit). - http now uses the nominal record header and adds the timeout-ms field (matching wit/nexum-runtime/http.wit), plus *.domain wildcard syntax in the allowlist example and the docstring on how non-2xx surfaces. Resolves PR #6 findings #2 and #3. * docs: defer typed config-value variant to 0.3 The shipped wit/nexum-runtime/types.wit ships 0.1's stringly-typed `type config = list<tuple<string, string>>`, but five doc locations plus the migration TL;DR promised a typed `config-value` variant for 0.2 (string/integer/boolean/list). Per architectural triage, defer the typed variant to 0.3 alongside the manifest parser work — the typing story lands as one coherent feature. Updates: docs/00, docs/01, docs/02 (two places), docs/08, migration guide TL;DR row + 'Typed config' subsection. Resolves PR #6 finding #4. * docs/migration: replace cargo-nexum vapor with real commands §9 verification checklist referenced 'cargo nexum check' and 'cargo nexum run --mock'; §11 promised 'cargo nexum migrate --from 0.1' as shipping with 0.2. None of these exist — there is no cargo-nexum crate in the workspace. Rewrite §9 to use real `cargo` + `just` invocations. Drop the §11 codemod promise; the sed cheat sheet in §8 already does the mechanical work. Add a clear 'no cargo-nexum toolchain in 0.2; coming in 0.3' note so adopters set the right expectation. Resolves PR #6 finding #7. * wit+engine: import clock/random/http in event-module; add host impls The new 0.2 capability interfaces (clock, random, http) shipped as standalone WIT files but were not imported by any world, so modules built against event-module / shepherd could not 'use' them. Their existence was advertised in the migration guide but was structurally unreachable. - event-module.wit: add 'import clock', 'import random', 'import http' (grouped as ambient host services after the six core primitives). shepherd world inherits via 'include event-module'. query-module remains intentionally sandboxed (no caps, no chain, no network). - Engine: add host impls for clock (SystemTime + monotonic_baseline: Instant), random (getrandom 0.4 fill), http (returns Unsupported for 0.2; real fetch is 0.3 — allowlist enforcement lands with #6). - Cargo.toml: add getrandom 0.4, plus serde 1 + toml 1 (for #6). Resolves PR #6 finding #5. * engine: minimal nexum.toml manifest parser with [capabilities] enforcement Per architectural triage, ship minimal manifest enforcement in 0.2 and defer optional-capability trap stubs to 0.3. The migration guide §3 promised four mechanisms; this commit lands the two security-critical ones (required-capability check + http allowlist enforcement) plus the deprecation warning, and explicitly defers per-import trap stubs. Manifest schema (parsed in crates/nexum-engine/src/manifest.rs): [module] name, version, component (sha256; parsed, not yet verified) [capabilities] required (validated against KNOWN_CAPABILITIES; engine rejects unknown names) optional (parsed + logged; trap-stub fallback is 0.3) [capabilities.http] allow (exact host or *.suffix wildcard) [config] TOML scalars flattened to strings (typed variant on 0.3 roadmap) CLI: nexum-engine <component.wasm> [<nexum.toml>]. If the second arg is omitted, the engine looks for nexum.toml next to the .wasm. If neither exists, it emits the deprecation warning and proceeds with empty config and empty allowlist (= effectively denies all HTTP). http::fetch now performs the per-module allowlist check (host extracted via a stdlib URL parser, exact or *.suffix match). Allowlist denial returns HostError { kind: Denied }; real network fetch is still 0.3. Includes unit tests for extract_host and host_allowed. Resolves PR #6 finding #6. * style: cargo fmt (nightly) CI rustfmt (nightly) collapses several multi-line signatures that the hand-formatted code had as multi-line. * rename WIT package nexum:runtime -> nexum:host (resolve engine/runtime naming overload) The 0.2 release shipped two similarly-named things — `nexum-engine` (the Rust crate hosting WASM components) and `nexum:runtime` (the WIT package). Both contain 'runtime' or a synonym, but they're at different layers: engine = implementation, runtime = contract. Worse, README.md described the engine crate as 'Host runtime — wasmtime-based component loader' — explicitly calling the *engine* 'runtime' while a sibling directory was literally named `nexum-runtime`. The word 'runtime' overwhelmingly means 'the thing that runs code' in programming usage; putting it on the contract side inverted the convention. Rename the WIT package to `nexum:host` — the host-imports surface a guest sees. Distinction becomes self-documenting: engine (nexum-engine) = a concrete implementation host (nexum:host) = the WIT contract every engine implements Touchpoints: - wit/nexum-runtime/ -> wit/nexum-host/ (12 files renamed via mv) - wit/shepherd-cow/deps/nexum-runtime/ -> wit/shepherd-cow/deps/nexum-host/ (regenerated by 'just sync-wit'; also covered by CI guard) - Every 'package nexum:runtime@0.2.0' -> 'package nexum:host@0.2.0' (12 files) - Every 'use nexum:runtime/...' -> 'use nexum:host/...' (shepherd-cow WIT) - Every 'nexum::runtime::...' -> 'nexum::host::...' (engine + example Rust) - justfile sync-wit paths - .github/workflows/ci.yml wit-deps-sync paths - All design docs (00..08), migration guide - README.md + docs/00 add an explicit 'Engine vs. host' callout so the distinction is directly apparent to a new reader. - A few stray 'host runtime' prose mentions in docs/05 and docs/07 changed to 'host engine' for consistency. Migration guide updated so a 0.1 -> 0.2 reader never encounters the mid-development 'nexum:runtime' name — the new package is `nexum:host` end-to-end. Build + run smoke clean; nightly rustfmt clean. * wit: drop deps/ vendoring; list both packages explicitly in bindgen The 0.2 release vendored a copy of wit/nexum-host/ under wit/shepherd-cow/deps/nexum-host/ because the engine's bindgen target (shepherd:cow/shepherd) imports from nexum:host via 'include', and wit-parser's default cross-package resolution looks at <pkg>/deps/. Maintained by 'just sync-wit' + a CI guard to catch drift. That whole pipeline was treating the symptom rather than the cause. Both bindgen macros (wasmtime::component::bindgen! and wit_bindgen::generate!) accept 'path' as an array of dirs, each holding one package. Listing both packages explicitly resolves the cross-package reference natively with no vendored copy. Changes: - crates/nexum-engine/src/main.rs: bindgen path is now ["../../wit/nexum-host", "../../wit/shepherd-cow"]; world fully qualified as "shepherd:cow/shepherd". - modules/example/src/lib.rs: world fully qualified as "nexum:host/event-module". Path stays single (the example doesn't import shepherd:cow). - wit/shepherd-cow/deps/ deleted entirely (12 files). - justfile: sync-wit recipe removed; build-runtime renamed to build-engine (clearer; matches the engine vs host vocabulary established earlier); check + run no longer depend on sync-wit. - .github/workflows/ci.yml: wit-deps-sync job removed (nothing to sync, nothing to drift). - docs/migration/0.1-to-0.2.md: checklist item about vendored deps rewritten to point at the new bindgen pattern. Result: 1 source of truth per WIT package, zero ceremony to keep them aligned, ~360 fewer lines of vendored bytes in the repo.
