fix(test): preserve coverage across native and Vitest loaders

[prekshivyas]

Coverage counts native CommonJS and Vitest calls against the same original TypeScript locations. The existing V8 collector can merge incompatible generated offsets and lose executed native calls. This prevents the protected E2E controller prerequisite for #12376 from meeting its unchanged coverage floor despite passing its behavioral tests.

Instrument original source before either loader transforms it, share counters across loaders, and merge only matching counter maps. Preserve reporting, shard transport, coverage floors, and uncovered code. Extract the existing native compiler/cache so instrumentation can be prepared before test timers without evaluating application code. Added dependencies are development-only.

The review repair addresses:

• Provider loading: externalize the TypeScript CommonJS collector in the root configuration as well as the project configuration. Exercise the real root/project configuration, shard merging, and conflicting maps.
• Source selection: match include and exclude patterns independently against relative and absolute paths, reject node_modules, and retain external-file and changed-file selection rules. Remove substring matching that incorrectly included excluded paths.
• Test isolation: restore the reservation fixture's isolated HOME before each of its eight existing cases. Install the warm-cache instrumenter guard before importing the loader and verify its cache remains empty.
• Lifecycle fixtures: distinguish exited zombies from live gateway processes and close the synthetic listener before exiting. Replace same-size model files atomically so filesystem-identity tests cannot depend on timestamp granularity. Production lifecycle behavior, existing assertions, deadlines, and cleanup requirements are unchanged.

Validation evidence for the repair:

• Focused regressions: 53 cases pass, covering 32 source-coverage, 13 loader, and eight reservation cases. Root-provider loading also has an observed failing reproduction followed by a 23-case passing run.
• Gateway fixture: 20 repeated lifecycle trials pass; final process-state handling passes 12 cases, all seven growth regressions, 18 repository checks, lint, and formatting. The preceding full run passed this gateway fixture.
• Model identity fixture: reuse the exact previously validated repair, with 68 file tests, 300 repetitions, and an omitted-replacement negative control.
• Full normal npm run check passed for the exact 16-file proposal on canonical main bced57c: all-file pre-commit hooks, full CLI/plugin suites, repository checks, growth checks and unchanged coverage floors. All 79 inputs (including incorporated main changes relative to the isolated snapshot) remained unchanged. CLI coverage: 85.74% lines, 84.04% statements, 87.82% functions, 78.26% branches. Plugin: 96.66%, 95.91%, 99.53%, 89.31%, respectively. Successful hooks suppress individual test totals, so no new case count is inferred.

The latest two-file repair shares each coverage fixture's existing test deadline across subprocesses and reports subprocess errors directly. No timeout was increased. The E2E host fixture now imports the same canonical gateway endpoint function directly, avoiding an unrelated lifecycle import graph before listener identity checks; ownership and executable assertions remain intact.

Validation for this repair: all 32 coverage tests and six real subprocess deadline probes pass; 190 combined host/gateway/growth tests, all 18 repository checks, lint, and formatting pass. A controlled diagnostic passed all 134 host cases with each import path, reducing the first identity case from 3.55 seconds to 27 milliseconds. This supports the import repair but is not a claim that the CI timeout was reproduced locally. The full check above covers the preceding exact 16-file proposal; these bounded repairs have focused validation and normal commit/publication hooks.

The prior candidate e2784a5 completed all scheduled feedback: core CI had one underlying failure (the first mocked listener identity case exceeded its existing 5-second deadline); the other 11 CLI shards passed. Managed activation passed on Docker (28 turns, three agents, 13 cleanup actions) and rootless Podman (19 turns, three agents, nine cleanup actions), with no build commands or cleanup failures. Docker exercised external images; that Docker-only path was unrun on Podman. CodeRabbit's remaining fixture deadline finding is addressed by this repair and awaits independent review.

Current candidate 39164ed5501f12260326d2d63a8937aecb428408 has green core CI, including all 12 CLI shards and the merged coverage gate. All nine specialists and the no-blockers gate in the full Advisor review passed. Actual CodeRabbit review completed; the reviewer withdrew both deadline findings and resolved the current thread and the older thread. All four actionable review threads are resolved by CodeRabbit. Optional performance and diagnostic suggestions remain documented.

Managed validation passed on Docker (28 turns, three agents, 13 cleanup actions) and rootless Podman (19 turns, three agents, nine cleanup actions), with no build commands or cleanup failures. Docker exercised external-image onboarding, identity-drift refusal, rebuild, and destruction; that Docker-only path was unrun on Podman. Public restarts and native OpenClaw approval passed.

The previous candidate 39164ed5501f12260326d2d63a8937aecb428408 completed full E2E run 37590927253, including four attempts on that unchanged head and base bced57c38baef60e74e0142378a74ae8a7b7ff73. The final attempt had 78 successful jobs, one executed leaf failure (OpenClaw provider switching), one aggregate failure, and 16 skipped jobs. Its targeted Hermes GPU compatibility job passed all ten runtime assertions and teardown. The OpenClaw leaf ran before merged #12720, whose focused 12-phase, six-cleanup validation passed separately. The approved Launchable opt-out remains a skip, not a passing test. Earlier attempt failures are retained in the run history; the final attempt does not waive them for a different head.

The preceding candidate d9dd577460faa972fc2c7feaadc30f749b822b94 completed managed validation: Docker and rootless Podman both passed. Its core CI remained red. In attempt 2, 11 of 12 CLI shards passed; shard 8 produced no output after starting the pinned Pi search-tool apt-get update and was cancelled at the existing 30-minute job limit. The coverage test never ran in that shard. This log identifies the stalled step, not its underlying network or lock cause. The earlier shard 6 deadline failure cleared on attempt 2. No green-core claim is made for d9dd577.

Previous candidate c315c921f2359597670b33296fc6a7e5a2d4a7ad is a signed, GitHub-verified merge of d9dd577 with main bdac003d725b5a21f3c8ce61ba39ebbf6d3c3ff7, incorporating merged #12720 and #12760. It bounds the existing pinned search-tool package-index update to three 120-second attempts with 20-second transport timeouts, and the pinned install to 180 seconds. Package versions, binary assertions, coverage floors, test deadlines, and the 30-minute shard limit are unchanged. Local checks passed: 18 repository checks, YAML and Bash syntax, a retry/fail-closed apt command probe, CLI build and typecheck, the normal signed commit hooks, and the normal pre-push publication gate. Eight focused source-coverage cases fail on local macOS with identical results on both d9dd577 and the current-main integration; they are not claimed to pass. Gate-true core CI run 37676044587 then failed in CLI shard 9 because the workflow contract fixture still expected one unbounded apt-get update call and exit 86. The new action retries three times and exits 1 after its final error. Other substantive shards passed except shard 7, which was cancelled during apt setup. Human review requested this contract test update and another exact-head CI and Advisor pass.

Current candidate 3b52b9ae4bf127bc327389fd4b944eedb5a84052 updates only that fixture: it verifies three bounded, identical update attempts, both retry notices, the final fail-closed error, and no install after update exhaustion. The separate Advisor runtime case still expects its single update call and original exit status. Focused integration tests pass (55 cases), selected repository checks pass (18), lint and formatting pass, and the normal npm run validate:pr and pre-push gates pass. The commit is signed and GitHub-verified.

Gate-true core CI run 37696446245 passed on its second attempt at the unchanged head. The first attempt's sole originating failure was a 5,022.84 ms timeout against an existing 5,000 ms limit in an unchanged route-reservation test in shard 6; the other 11 CLI shards, including the repaired contract test in shard 9, passed. A user-authorized targeted rerun of only shard 6 (plus GitHub-required dependencies) passed, as did merged CLI coverage and the final required checks gate. No test deadline or coverage floor changed.

Managed-image validation passed both Pi architectures, direct managed startup, and Docker and rootless Podman all-agent activation. Self-hosted PR qualification passed, including the generic NVIDIA GPU llama.cpp test. CodeRabbit's exact-head review found no actionable inline issue; its argument-order suggestion is a non-blocking nitpick. The exact-head Advisor run passed with all nine specialists clear, zero findings, and a successful no-blockers gate; its receipt is published. All required checks pass. Human review approval remains required; the PR is not approved or merged. This prerequisite does not establish that the protected controller or original #12376 full E2E passes.

Merge Risk: 🔵 Low · up to 3b52b

This change adds bounded APT retries and tests that cover them. The remaining risk is that coverage tests which chain several subprocesses could time out intermittently on slow CI runners. That is a minor reliability issue and is safe to follow up after merge.

138-172: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

The "warm disk cache" test does not prove that the cache was hit.

This test patches Module._load only after require(SOURCE_REQUIRE_HOOK) and the source-coverage.cts require have run. The test then requires the probe and asserts its counters. There are two problems:

• If the compiler or coverage helper loads @babel/core or istanbul-lib-instrument eagerly, the guard never sees that load.
• If the helper loads those modules lazily through a captured require, the load may not go through the patched Module._load at call time.

In both cases the test can pass while instrumentation runs on a cold path. Install the guard before requiring the hook and the helper. Or assert directly that require.cache contains no instrumenter entries after the probe loads.

Proposed fix

 const script = `
+const Module = require("node:module"), load = Module._load;
+Module._load = function(request, ...args) {
+  if (request === "@babel/core" || request === "istanbul-lib-instrument") throw new Error("Warm native cache attempted instrumentation");
+  return load.call(this, request, ...args);
+};
 require(${JSON.stringify(SOURCE_REQUIRE_HOOK)});
 const coverage = require(...);
 coverage.enableSourceCoverage({...});
-const Module = require("node:module"), load = Module._load;
-Module._load = function(request, ...args) { ... };
 const probe = require(${JSON.stringify(filename)});
+if (Object.keys(require.cache).some((k) => /[\\/](@babel[\\/]core|istanbul-lib-instrument)[\\/]/.test(k))) throw new Error("Instrumenter loaded");

@coderabbitai full review

Please review current head 39164ed. The prior full review completed; automatic review of this new commit was skipped because this remains a draft.

For the remaining finding in review comment 4203911405, each fixture now shares its existing test deadline across all child processes. Every child is capped by both its original timeout and the remaining shared budget, and subprocess errors fail explicitly. Outer deadlines and assertions are preserved. The CI listener-identity timeout is addressed by importing the same canonical endpoint function directly instead of the broad re-export module; ownership and executable checks remain unchanged.

Validation: 32 coverage tests plus six subprocess deadline probes; 190 combined host/gateway/growth tests; all 18 repository checks, lint, and formatting. Normal signed commit hooks, publication validation, and CLI typecheck passed. New CI is running; the prior candidate's Docker and Podman activation both passed. Full E2E remains a separate requirement.

44-53: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Make the isAlive state check more portable and consistent.

ps -p <pid> -o stat= is POSIX-compatible, so the call is acceptable. Two details need attention.

• The knownState regex accepts W, Z, X, and x (Line 50). The return regex (Line 53) accepts W but not Z, X, or x. A state of W therefore counts as alive. The comment on Line 52 mentions only zombies. Align the two sets, or remove W if it is not intended.
• If ps fails to spawn, for example when the binary is missing or the 5-second timeout fires, result.status is null. The assertion then fails with the generic message "could not be inspected". The message hides the cause. Include result.error in the message.

The change is low impact. The fixture works for the expected cases.

77-95: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Cache map identities per filename in mergeSourceCoverage.

readCoverageFiles calls onFileRead once for each per-test-file coverage dump. takeCoverage returns every file that the worker has loaded so far, so each dump can hold hundreds of files. For each incoming file, the current code does four things:

• It allocates map.files().
• It runs a linear includes over that array.
• It calls fileCoverageFor(filename).toJSON().
• It runs JSON.stringify on two sets of statement, function, and branch maps.

The total cost is about test files × loaded files × (map size + file count). On a full CLI coverage run, this adds a large serial CPU cost to report generation and shard merging.

Compute the identity once per filename. After that, compare only the incoming identity.

Proposed fix

   mergeSourceCoverage(map, incoming) {
+    this.sourceIdentities ??= new WeakMap();
+    let identities = this.sourceIdentities.get(map);
+    if (!identities) this.sourceIdentities.set(map, (identities = new Map()));

generateCoverage adds untested files directly with map.addFileCoverage. Those files never conflict, because they are added only when map.files() does not already contain them.

Update mergeSourceCoverage to cache each filename’s coverage-map identity per
coverage map, computing and validating the incoming identity once and comparing
it with the cached value instead of repeatedly scanning map.files() and
serializing prior coverage. Preserve the conflicting-identity error for
mismatches; files added directly by generateCoverage need no cache entry.

Reviewed exact commit c315c921f2359597670b33296fc6a7e5a2d4a7ad against base 5b0548164733ebcf56ac4a08b09ea47eb2b297de. I did not find a blocking product or security defect in the source-coverage, cache-locking, admin-approval fixture, or dependency changes. Security review: PASS across secrets, injection, authorization, network policy, container isolation, dependencies, data exposure, integrity, and workflow security. The new dependencies are development-only, the cache and stats writes retain bounded path and symlink protections, and shell inputs remain quoted or typed.

I am leaving a Comment rather than Approve because the exact head is not ready:

• CI / Pull Request / cli-test-shards (9) fails in test/automation/pull-requests/pr-workflow-contract.test.ts. The action now retries apt-get update three times and exits 1 after exhaustion, while the contract still expects the fake sudo status 86 and a single direct apt-get invocation. Update the contract to exercise the bounded retry behavior, including the three attempts and final error status or marker, then rerun CI.
• The latest PR Review Advisor receipt covers 39164ed, not this exact c315c921 head. Obtain an exact-head Advisor result after the repair.

All other visible checks are terminal; the remaining CodeRabbit threads are resolved and its current delta review has no actionable finding.

Assert the required command properties, not the complete argument order.

The exact array comparison fails if equivalent APT options change order. Keep the retry and failure-output checks. Check the timeout and Ubuntu source options without requiring an exact copy of the command’s argument order. As per path instructions: “Prefer observable outcomes through the public boundary over source-text, private-shape, or mock-call assertions.”
