Summary by CodeRabbit

  • New Features
    • Deployment generation now supports dekit, creating a dekit.yaml alongside the Mise configuration. Generated instructions include commands to start, attach to, and stop scenario tasks, plus open the OpenObserve interface.
    • Dekit tasks start services in dependency order and wait for health checks before dependent services run.
    • WASI Runner now supports passing WebGPU options to its runtime.
  • Bug Fixes
    • Updated WebAssembly exception handling for newer Clang versions.
    • Updated the WebAssembly runtime and related components, including security fixes.
    • Runner names that do not meet the required naming format are now rejected with a clear error.

📝 Walkthrough

Walkthrough

The CLI adds dekit deployment output with generated task dependencies and readiness checks. The change also updates platform-specific mise rules, Wasmtime dependencies, WASI WebGPU state, WebAssembly compatibility code, and generated documentation.

Changes

Dekit deployment output

Layer / File(s) Summary
Build dekit task configuration
utilities/cli/src/deployment_types/*, utilities/cli/src/lib.rs, utilities/cli/src/error.rs
Adds dekit task generation, shared YAML serialization, scenario-specific collector names, and RFC 1123 runner-name validation.
Wire dekit into CLI generation
utilities/cli/src/input.rs, utilities/cli/src/lib.rs, utilities/cli/HELP.md, utilities/cli/tests/*
Adds the dekit output type, generates mise.toml with dekit.yaml, renders dekit instructions, and tests the generated output.
Update generated verification outputs
verification/local/output/*, verification/published/output/*
Adds dekit configurations and usage instructions. Generated mise tasks use scenario-specific OpenObserve container names.

Platform and runtime maintenance

Layer / File(s) Summary
Remove platform mise OS scopes
.mise/config.*.toml, config/conftest/policy/mise/mise.rego, config/semgrep/mise-config.yaml, CHECKS.md
Removes OS restrictions from selected tool entries. Policy and Semgrep checks reject OS-scoped entries in platform-specific mise files.
Upgrade Wasmtime and runner state
Cargo.toml, config/deny.toml, config/osv-scanner.toml, services/ws-wasi-runner/*
Updates Wasmtime-related dependencies, removes matching advisory ignores, and stores default WebGPU options in HostState.
Adjust WebAssembly code generation
services/ws-modules/zig-except1/src/exceptions.cpp, utilities/int-gen/src/zig.rs, utilities/int-gen/src/zig.in/client_deinit_body.zig
Adds the Clang 22 exception tag definition and scopes Zig method rewriting to Client.deinit, which now uses a no-op body.
Update repository guidance
AGENTS.md, README.md, config/semgrep/no-task-name-mentions.yaml
Updates review, coverage, dependency, install-link, generated-output, and Semgrep exclusion guidance.

Merge Risk: 🔵 Low · up to 88ed5

The deployment changes appear mergeable, but the coverage guidance should be corrected so contributors know that the changed-branch target is not currently enforced.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 88ed5

The new orchestration retains scenario-scoped collector names and loopback-only collector exposure. No new exploitable security boundary bypass was established. Failed or concurrent regeneration can nevertheless leave mismatched startup and cleanup configurations, and external runtime behavior remains partly unverified.

Retained concerns

  • Low · reliability · inferred: Mise and Dekit configurations are replaced sequentially without a shared commit or rollback. If regeneration changes the scenario and the later write fails, reusing the output directory can combine new startup commands with a stale scenario-specific Docker stop target. Concurrent generation can produce the same mismatch. Successful generation resolves and validates runners, and write failures propagate to callers; the concern requires reuse after failure or overlapping writers. Direct writes already existed, but the new delegated task graph adds a cross-file cleanup-ownership invariant.
Security review details

Security Blast Radius

  • inferred — The evidenced deployment authority is local process execution and Docker operations using the invoking user's permissions. Cleanup targets openobserve-{cluster_name}, not the bare repository collector name. This is scenario-name scoping on one Docker daemon, not a demonstrated tenant or privilege-isolation boundary.

Trust Boundaries and Controls

  • observed — The runner-name path rejects option-like names such as --help before they can become Mise task arguments. Reserved task names and duplicate identities are also rejected. Collector creation and Dekit cleanup use the same scenario-name helper.
  • inferred — No repository-local guest-controlled setter for the new WebGPU options was identified. Default construction and borrowing preserve the observed per-store ownership pattern, but unavailable upstream option semantics prevent a complete assessment of effective device authority.

Resilience and Maintainability Implications

  • inferred — Explicit Docker cleanup addresses a client exiting before forwarding an interrupt, and scenario-specific naming narrows accidental cleanup reach. It does not establish recovery after supervisor termination or distinguish simultaneous invocations sharing a cluster name. The fixed collector port remains a shared-host contention constraint.

Hardening Proposals

  • proposed — Publish the credential and paired task configurations as one versioned generation, or otherwise reject mixed generations and serialize writers. This would preserve startup-to-cleanup ownership when regeneration is interrupted; it is a containment improvement, not evidence of an exploitable vulnerability.

41-41: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Hard-coded task names duplicate the mise.rs task names.

dekit.rs uses the literals "openobserve", "ws-server" and "open-o2". Each must match a task that generate_mise_deployment inserts. A rename on one side leaves dekit up calling mise run <name> for a missing task. A test covers the current names, so drift is caught at test time.

Share these names as pub(crate) constants in mise.rs, as is already done for COLLECTOR_CONTAINER. This is optional.

Also applies to: 51-51, 53-53, 67-68
