The browser example harnesses alias @openzeppelin/miden-multisig-client and @openzeppelin/guardian-client to packages//dist/index.js, so they run the built package rather than src. dist/ is gitignored, so a build produced on another protocol line survives every branch switch and keeps being served until something rebuilds it. The MASM baked into that dist then meets a different @miden-sdk/miden-sdk WASM assembler and fails at account creation with a bare "Failed to compile account component: invalid syntax". A foreign branch can likewise leave an out-of-range @miden-sdk/miden-sdk installed that the workspace's own lockfile does not pin. Neither condition is visible to any source-level check.

Add scripts/preflight-browser-smoke.sh, which reports, fixes, then re-verifies both: installed @miden-sdk/miden-sdk against each workspace's lockfile pin rather than its package.json range, which a caret hides, and packages/*/dist older than its src. --check reports without writing. Rebuilds run clean before build because export names differ across protocol lines, so tsc alone leaves orphaned files from the previous build.

Wire it into the smoke-test-ts-multisig-sdk quick start and its workflow-matrix environment block, and into the guardian-validation-matrix browser command set. Add a Stale Build Output section recording the symptom, the MASM dialect markers that identify it, and an instruction not to report it as an SDK or contract bug until the preflight passes.

Also correct the Testing Deployed SDKs claim that npm run dev smokes the workspace source. It smokes the workspace build output.

Summary by CodeRabbit

  • New Tools

    • Added a browser validation preflight that detects missing, stale, or mismatched SDK builds.
    • Added automatic remediation to reinstall dependencies, rebuild packages, and clear browser build caches when needed.
    • Added a check-only mode for reporting issues without modifying files.
  • Documentation

    • Updated browser testing and validation guidance with the required preflight step.
    • Added troubleshooting instructions for stale build artifacts and dependency mismatches, improving reliability after branch changes.

The browser example harnesses alias @openzeppelin/miden-multisig-client and
@openzeppelin/guardian-client to packages/<name>/dist/index.js, so they run the
built package rather than src. dist/ is gitignored, so a build produced on
another protocol line survives every branch switch and keeps being served until
something rebuilds it. The MASM baked into that dist then meets a different
@miden-sdk/miden-sdk WASM assembler and fails at account creation with a bare
"Failed to compile account component: invalid syntax". A foreign branch can
likewise leave an out-of-range @miden-sdk/miden-sdk installed that the
workspace's own lockfile does not pin. Neither condition is visible to any
source-level check.

Add scripts/preflight-browser-smoke.sh, which reports, fixes, then re-verifies
both: installed @miden-sdk/miden-sdk against each workspace's lockfile pin
rather than its package.json range, which a caret hides, and packages/*/dist
older than its src. --check reports without writing. Rebuilds run clean before
build because export names differ across protocol lines, so tsc alone leaves

Browser smoke preflight

Layer / File(s) Summary
Preflight scan and status handling
scripts/preflight-browser-smoke.sh
Adds checks for SDK version drift, missing packages, and stale or missing dist output.
Preflight remediation and rescan
scripts/preflight-browser-smoke.sh
Adds workspace reinstalls, clean package builds, Vite cache removal, and post-fix validation.
Smoke-test usage and troubleshooting
.agents/skills/smoke-test-ts-multisig-sdk/SKILL.md
Documents built-package resolution, required preflight execution, stale builds, dependency drift, MASM diagnostics, and cache clearing.
Validation command integration
.agents/skills/guardian-validation-matrix/references/command-matrix.md, .agents/skills/smoke-test-ts-multisig-sdk/references/workflow-matrix.md
Runs the preflight before browser builds, SDK tests, typechecking, and application builds.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 51fe2

The preflight can mutate the workspace after a mistyped option and can report success when the SDK version is not verifiable, allowing stale or incompatible browser builds to proceed undetected. Merge should wait until these validation and safety issues are fixed.

Poem

A rabbit checks the builds at dawn,
Finds stale paths and moves them on.
SDKs align, caches clear,
Browser smoke runs bright and clear.
Hop, test, and ship with cheer!

- Around line 57-59: Update the fenced diagnostic block containing “Failed to
compile account component: invalid syntax” to specify text as its language
identifier, preserving the existing output content.

In `@scripts/preflight-browser-smoke.sh`:
- Around line 26-27: Update the argument parsing around CHECK_ONLY in
preflight-browser-smoke.sh to reject any option other than --check, including
extra arguments, before performing drift scanning or fix-mode actions. Preserve
--check as report-only mode and the no-argument invocation as fix mode.
- Around line 107-120: Update the SDK validation flow around declared_sdk,
installed_sdk, and locked_sdk so an empty locked_sdk result is treated as an
unresolved lockfile error rather than a clean workspace. Record the workspace in
the existing drift/error tracking and ensure the script exits nonzero; retain
the current mismatch handling for non-empty pins, but do not recommend npm ci as
the repair for a missing lockfile pin.

It reports, fixes, then re-verifies two things source-level checks cannot see: a workspace whose installed `@miden-sdk/miden-sdk` does not match its own lockfile pin, and a `packages/*/dist` older than its `src`. Use `--check` to report without writing. See Stale Build Output below for why this class of failure is silent.
