Warning Review limit reached
Next review available in: 11 minutes You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR introduces hardware detection, model planning, environment generation, and optional model fetching, but the current implementation can hang during probing, mis-detect hardware on Windows or macOS, download models that were not selected, accept malformed model metadata, and write logs through a predictable temporary path. These issues can prevent setup, produce incorrect configurations, or cause unintended file writes, so the PR is not safe to merge until the major risks are addressed.

Inline comments:
In `@apps/backend/local-stack/README.md`:
- Around line 28-40: Remove the obsolete `.env.example` copy command from the
README quick-start preamble and replace that setup block with the existing `bun
run stack init` wizard flow, so `.env` is created only by the wizard without an
overwrite confirmation.
In `@apps/backend/local-stack/scripts/check.sh`:
- Around line 252-257: Update the AC-8 setup around INIT_ENV to create a private
temporary directory and place the init command log inside it instead of using
/tmp/aikami-init.out. Add an EXIT cleanup trap for that directory so the
temporary environment and log are removed on every exit path, and update the
failure tail command to use the private log path.
- Around line 266-273: Update the Docker Compose validation command in the AC-10
check to load the generated environment file by passing INIT_ENV through the
compose --env-file option. Preserve the existing COMPOSE_FILE and
COMPOSE_PROFILES handling and success/failure reporting.
In `@apps/backend/local-stack/stack/init.test.ts`:
- Around line 132-140: Update the “--yes writes the .env with the full plan
visible” test around runInit to capture process.stdout.write, then assert the
rendered plan output includes its heading and selected models, while preserving
the existing .env assertions.
- Around line 196-208: Update the recommend call in the separator test to pass
backendOverride: 'cpu', ensuring the generated plan always uses the CPU backend
regardless of detected host hardware while preserving the existing
platform-specific separator assertions.
In `@apps/backend/local-stack/stack/init.ts`:
- Around line 375-379: Update the --fetch branch in the local stack
initialization flow and the fetcher’s run interface to use the generated plan:
pass the selected manifest path, modalities, accepted licences, and all planned
plan.models manifestId values, extending run to accept multiple entry IDs or
invoking it once per planned model. Ensure fetching is limited exactly to the
planned models rather than default profiles or the full manifest.
- Around line 410-412: The --backend auto value must not reach planning because
selectBackend() and renderEnv() cannot resolve it. Update parseArgs to map auto
to undefined before constructing the stack plan, preserving explicit backend
values; in apps/backend/local-stack/README.md lines 91-94, update the documented
--backend behavior to match this handling.
In `@apps/backend/local-stack/stack/probe_executor.ts`:
- Around line 58-92: Update the timer callback in the child execution flow to
settle the timeout result immediately after killing the child, rather than
waiting for the close event. Preserve the existing settled guard in the close
handler so it returns without settling again when the timer has already resolved
the operation; keep normal exit and spawn-error handling unchanged.
In `@packages/shared/local-ai/src/lib/dependency.test.ts`:
- Around line 17-22: Update NODE_BUILTIN_PATTERNS in the dependency boundary
test to match Node built-in subpaths such as node:fs/promises and to detect
imports from bun, while preserving the existing checks for child_process, fs,
os, and path.
In `@packages/shared/local-ai/src/lib/detect.ts`:
- Around line 213-223: Update core detection in detect.ts around the platform
probe branch: use a PowerShell NumberOfLogicalProcessors probe on win32, pass -n
to the darwin sysctl invocation, and extract numeric digits before converting
the result instead of parsing the entire output line. In
packages/shared/local-ai/src/lib/detect.test.ts lines 144-190, change the darwin
fixture to “hw.ncpu: 10”, remove the win32 nproc stub, and stub the new
PowerShell probe.
In `@packages/shared/local-ai/src/lib/fixture_executor.ts`:
- Around line 56-60: Update the fixture lookup in run to compare argument
vectors structurally: require matching lengths and verify each corresponding
argument value, instead of comparing join(' ') results. Preserve the existing
command matching and fallback behavior.
In `@packages/shared/local-ai/src/lib/probe_executor.contract_suite.ts`:
- Around line 82-88: Update the readTextFile contract test to assert result.ok
before inspecting stdout, ensuring a failed read causes the test to fail rather
than skipping the newline assertion; then retain the existing endsWith('\n')
check for the successful result.
- Around line 47-112: Update the ProbeExecutor contract suite to remove POSIX
and Linux-specific assumptions: replace sh, sleep, and printf invocations with
platform-independent command fixtures, and replace the /proc/1/mem permission
test with a deterministic permission-denied fixture. Alternatively, expose and
check explicit executor capabilities so only unsupported cases are skipped;
preserve the existing result and timeout assertions for supported environments.
In `@packages/shared/local-ai/src/lib/recommend.test.ts`:
- Around line 125-360: Add tests covering RecommendOptions.tierOverride and the
metal backendOverride branch in recommend: verify tierOverride 'cpu' on a 24 GB
VRAM profile selects the CPU-tier model without a nominal-tier warning, and
verify backendOverride 'metal' on a Linux profile emits the expected warning
while setting nativeEngines to true.
In `@packages/shared/local-ai/src/lib/recommend.ts`:
- Around line 147-170: Move the containerRuntime === 'none' warning logic out of
the vendor switch so it is applied for every non-native backend, while
preserving the existing vendor-specific backend selection and NVIDIA passthrough
warning behavior. Keep the warning suppressed when a native runtime is
available.
In `@packages/shared/local-ai/src/lib/tier_table.test.ts`:
- Around line 5-48: Extend the tier_table tests with exact-threshold assertions
for tierForUsable at 4 GiB and 10 GiB, plus an assertion that one byte below 10
GiB remains in the 8gb tier. Add a usableBytesForProfile case for an NVIDIA
profile with vramMb set to 0, verifying it falls back to the
unified-memory-style RAM calculation.
In `@packages/shared/schemas/src/lib/local_ai/model_manifest.ts`:
- Around line 29-38: Update the manifest schema and parseManifest validation so
file entries require either url or all of repo, revision, and file, archive
entries require url, bytes is a non-negative integer, and sha256 is exactly 64
hexadecimal characters. Add rejection tests covering each invalid source and
integrity case while preserving valid manifest parsing.

Remove the obsolete .env.example setup step.
The preamble still tells users to run cp .env.example .env. This creates .env before stack init runs. The wizard then shows an overwrite diff and requires a second confirmation.
Replace the preamble command block with the new wizard flow. This keeps the quick start consistent with the claim that users do not need manual environment setup.

Use a private temporary log file.
/tmp/aikami-init.out is predictable. A local attacker can create a symlink at that path before the shell redirection opens it. The check can then truncate or write to the symlink target with the privileges of the user running the script.
Create the log inside the existing mktemp -d directory. Add a cleanup trap so all temporary files are removed on every exit path.

Docker Compose CLI --env-file COMPOSE_FILE environment variable interpolation precedence documentation
💡 Result:
Docker Compose uses specific precedence rules for variable interpolation when resolving values in your Compose file [1][2]. When multiple sources define the same variable, the precedence order (from highest to lowest) for interpolation is [1][2]: 1. Shell environment variables: Variables already set in your current shell session take the highest precedence [1][2]. 2. Environment file via --env-file: If you use the --env-file CLI flag, variables defined in this file take precedence over default files [1][2]. 3. Default.env file: If --env-file is not specified, Compose searches for an.env file in the project directory [1][2]. The project directory is determined by the --project-directory flag (if set), the directory of the first Compose file specified, or the current working directory (PWD) [1][2]. Note that variable interpolation refers to substituting values directly into the Compose YAML file itself [1]. This is distinct from environment variables passed into the service container's environment (e.g., using the environment or env_file attributes in the YAML), which follow a different precedence hierarchy [3][4]. Regarding COMPOSE_FILE: The COMPOSE_FILE environment variable is a pre-defined variable used to specify the path(s) to your Compose file(s) [5][6]. It is equivalent to using the -f flag [7][6]. Because it is an environment variable itself, it is subject to the same shell-level availability as other variables [7]. If flags are explicitly set on the command line (like -f), they override the value of the COMPOSE_FILE environment variable [7].

Assert the plan output.
This test only checks generated .env content. It does not verify that renderPlan() output is visible before the write.
Capture process.stdout.write and assert the plan heading and selected models. This prevents a regression that removes plan presentation while this test still passes.
As per path instructions, **/*.test.ts must only flag “missing edge cases, false-positive assertions, or improper mocking logic.”

Force the CPU backend in the separator test.
This test uses live hardware detection and calls recommend() without backendOverride. On a host with a supported GPU, the plan can select CUDA, ROCm, or another backend. The Linux assertion then incorrectly expects compose.cpu.yaml.
Pass backendOverride: 'cpu' so the test isolates separator behavior from host hardware.
Proposed fix
- const plan = recommend({ profile, modalities: ['text'], manifest });
+ const plan = recommend({
+ profile,
+ modalities: ['text'],
+ manifest,
+ backendOverride: 'cpu',
+ });As per path instructions, **/*.test.ts must only flag “missing edge cases, false-positive assertions, or improper mocking logic.”

Assert that readTextFile succeeds.
If readTextFile returns an error result, the conditional skips the assertion and the test passes. Assert result.ok before checking stdout. This prevents a failed read from satisfying the contract test.

The missing container runtime warning only fires for vendor: 'none'.
The warning at Line 164 sits inside case 'none'. On an AMD, Intel, or NVIDIA profile with containerRuntime === 'none', the plan reports a container backend and no warning. init.ts then writes a compose-based .env that cannot start. Move the check out of the switch so it applies to every non-native backend.

the containerRuntime === 'none' warning logic out of the vendor switch so it is
applied for every non-native backend, while preserving the existing
vendor-specific backend selection and NVIDIA passthrough warning behavior. Keep
the warning suppressed when a native runtime is available.

Add boundary and zero-VRAM cases.
Three behaviors that the tier logic depends on are untested:
tierForUsable(4 * GIB)andtierForUsable(10 * GIB)at the exact thresholds.tierForUsable((10 * GIB) - 1)staying at8gb.usableBytesForProfilewithgpuVendor: 'nvidia'andvramMb: 0, which must fall through to RAM sizing.

Extend the tier_table tests with exact-threshold assertions for tierForUsable at
4 GiB and 10 GiB, plus an assertion that one byte below 10 GiB remains in the
8gb tier. Add a usableBytesForProfile case for an NVIDIA profile with vramMb set
to 0, verifying it falls back to the unified-memory-style RAM calculation.

Enforce manifest source and integrity constraints. parseManifest accepts file entries without a direct url or complete repo/revision/file source, archive entries without url, negative or fractional bytes, and invalid sha256 strings. Since recommend sums bytes into totalDownloadBytes, invalid values can produce an incorrect download plan. Require either a direct URL or complete Hugging Face fields for file, require url for archive, constrain bytes to a non-negative integer and sha256 to 64 hexadecimal characters, and add rejection tests.

Pipeline Status: review
Contract: C-391 —
stack init— Hardware Detection, Modality Selection, and Model RecommendationContract Status: implemented ✅
Pipeline Stage: review (waiting for human review)
What was built
A new portable planning core
packages/shared/local-ai(@aikami/local-ai) with the ProbeExecutor seam (Bun/CLI + fixture-replay adapters, shared AC-0c contract suite), TIER_TABLE + headroom rules, manifest loader, hardware detection, and purerecommend(). TypeBox schemas inpackages/shared/schemasand derived types inpackages/shared/types(StackBackend/StackModality/HardwareProfile/StackPlan/ModelManifest). CLI wizard inapps/backend/local-stack/stack(init.ts,env_writer.tswith atomic write/diff/backup,probe_executor.ts) with full flag coverage, plan-before-write, disk guard,--json, platform-correct COMPOSE_FILE separator. Wiredbun run stack initfrom repo root, moon init task, check.sh AC-8/AC-10 hooks, README + docs quick-start rewritten to two commands.New user journey:
bun run stack init && docker compose up -d— detection in <3s, no network, graceful CPU fallback.Verification
Verdict: PASS — all 14 ACs (AC-0…AC-13) implemented and verified. Live host verification:
stack init --yes --jsonexits 0 with schema-valid HardwareProfile+StackPlan; NVIDIA GPU + docker without toolkit triggers AC-12 CPU fallback + warning; plan printed before write (AC-7);.envwritten with:separator and renders viadocker compose config(AC-10/11);--modalities text→COMPOSE_PROFILES=text(AC-5);--backend cuda→ compose.cuda.yaml (AC-2/8); re-run shows diff, decline leaves hand-edit byte-identical (AC-9);--disk-path /proc→ exit 2 with GB shortfall + next-tier suggestion (AC-6).Affected projects (docs, local-ai, local-stack, schemas, types) pass fix + typecheck. Aggregate validate() failures are confined to the pre-existing
scripts/project at base commit — untouched by this contract.Files changed
