Note: internal/metal tests fail in worktree environments due to module- resolution drift — go mod tidy stripped legacy `replace` directives that pinned go-inference + go-io to their dAppCore mirrors.

Inline comments:
In `@api_darwin.go`:
- Line 113: The error message assigned to quantErr uses American spelling
"quantization"; change the string in the quantErr declaration (variable name
quantErr) to use UK spelling "quantisation" so it reads something like "mlx:
loaded model quantisation does not match requested bits" while keeping the rest
of the message intact.
In `@ax7_generated_test.go`:
- Around line 9-13: The tests use the non-discoverable signature func
TestAX7_AdamW_Reset_Good(t *core.T) and have a dead 'symbol' variable; change
each test to the standard Go test signature func TestAX7_AdamW_Reset_Good(t
*testing.T) (add the testing import), compute the runtime/reflect name for the
referenced method (e.g., derive the name for (*AdamW).Reset via reflection or
runtime.FuncForPC from the 'symbol' value) and pass that derived name into
core.AssertContains instead of comparing two literals; also keep the
core.AssertNotNil(t, symbol) assertion but ensure 'symbol' is actually used in
the subsequent check so the test validates the real metadata (apply the same
pattern for all TestAX7_* functions).
In `@gguf_info.go`:
- Around line 193-203: The filepath.WalkDir callback is swallowing traversal
errors and the outer WalkDir error is also ignored; change the callback in
filepath.WalkDir to return walkErr when walkErr != nil (instead of nil) so
WalkDir can stop and report errors, and update the outer handler (the if err :=
filepath.WalkDir(...) block) to return that err (not nil) so callers see the
failure; keep the existing short-circuit for non-directories (when d.IsDir() is
false) and continue using probeDiscoveredModel and appending to models as
before.
In `@go.mod`:
- Around line 10-13: The go.mod shows a version mismatch: the module
dappco.re/go is required at v0.9.0 while dappco.re/go/core is pinned to
v0.8.0-alpha.1; update the dependency alignment by either bumping
dappco.re/go/core to v0.9.0 (or the same semver as dappco.re/go) or downgrade
dappco.re/go to match core, and if you intentionally keep mixed versions add a
clear compatibility note and rationale in the module's documentation (or a
comment) referencing the two modules dappco.re/go and dappco.re/go/core so
reviewers know the compatibility guarantee.
In `@internal/metal/qwen3.go`:
- Line 10: You introduced "dappco.re/go" at v0.9.0 in the import in qwen3.go
while go.mod still pins dappco.re/go/inference and dappco.re/go/io at
v0.8.0-alpha.1; resolve the version drift by aligning all dappco.re/go* modules
to the same version (either upgrade the inference and io modules to v0.9.0 or
downgrade the root import to v0.8.0-alpha.1), update the go.mod entries
accordingly for dappco.re/go, dappco.re/go/inference and dappco.re/go/io, then
run module resolution (go get ./... or go mod tidy) and verify code compiles
against the chosen version.
In `@internal/tokenizer/ax7_generated_test.go`:
- Around line 7-10: The test function TestAX7_FormatGemmaPrompt_Bad currently
accepts *core.T so it won't be discovered by go test; change its signature to
func TestAX7_FormatGemmaPrompt_Bad(t *testing.T), add the "testing" import, and
update the assertion calls that currently accept *core.T
(core.AssertNotNil/core.AssertContains) to either use standard testing utilities
or wrap the *testing.T into the core test helper if a constructor exists (e.g.,
core.NewT(t)) so the assertions still compile and behave the same.
In `@mlxlm/ax7_generated_test.go`:
- Around line 9-13: The test uses the wrong signature and ineffective
assertions: change the function TestAX7_Backend_Available_Good to the standard
Go signature func TestAX7_Backend_Available_Good(t *testing.T) (import testing),
update any other TestXxx functions using core.T to *testing.T, and replace the
hard-coded AssertContains checks with meaningful assertions against the
retrieved symbol from any((*mlxlmBackend).Available) — e.g., use
core.AssertNotNil(t, symbol) and assert the symbol's name/type/value (not string
literals) or cast/check it implements the expected method signature for
mlxlmBackend.Available so the test actually validates the symbol.
In `@mlxlm/backend.go`:
- Around line 760-767: The code currently folds closeFiles(...) into err
immediately after os.StartProcess, which can return an error from closing parent
FDs while the child (process variable from StartProcess) may have started and
thus be leaked; change the logic in the StartProcess block so you first check
startErr := err from os.StartProcess separately, and if startErr == nil then
call closeErr := closeFiles(stdinRead, stdoutWrite, stderr); if closeErr != nil
then call process.Kill() and process.Wait() (or Wait to reap) and return a
joined error combining core.E("mlxlm.process","start "+command, closeErr) plus
any additional closeFiles(stdinWrite, stdoutRead) cleanup; only when startErr !=
nil return the original startErr joined with closeFiles(stdinWrite, stdoutRead)
as before. Ensure you reference the process variable returned by
os.StartProcess, the closeFiles(...) calls, and the error construction via
core.E("mlxlm.process","start "+command, ...) so the child is terminated and
reaped if parent-side close fails.
In `@pkg/daemon/ax7_generated_test.go`:
- Line 10: The AssertContains calls are tautological (comparing two hard-coded
strings) and should be replaced with meaningful checks: either use
core.AssertNotNil(t, symbol) when you only want to ensure the symbol is present,
or assert the symbol's actual metadata (e.g., core.AssertEqual(t, expectedName,
symbol.Name) or compare symbol.Metadata.Name) when you want to validate the
reported name; update each invocation of core.AssertContains (e.g., the
"DefaultRegistryForDaemon_Good"/"DefaultRegistryForDaemon" lines and the other
listed occurrences) to reference the runtime symbol variable (symbol) and its
fields (symbol.Name or symbol.Metadata) or use AssertNotNil as appropriate.
In `@tests/cli/violet/main.go`:
- Around line 61-63: The current conditional "if err := cmd.Wait(); err != nil
&& ctx.Err() == nil" is ineffective because cancel() was already called so
ctx.Err() is non-nil; instead detect cancellation by checking the error value
itself. Replace the ctx.Err() check with an errors.Is check (e.g.,
errors.Is(err, context.Canceled) or context.DeadlineExceeded) and only log when
the process error is not a cancellation: call cmd.Wait(), then if err != nil &&
!errors.Is(err, context.Canceled) { fmt.Fprintf(os.Stderr, "wait violet: %v\n",
err) }, and add the necessary import for the errors package; reference
cmd.Wait(), ctx.Err(), cancel(), and context.Canceled when making the change.

🌐 Web query:
Does go testdiscoverfunc TestXxx(t *core.T)whencore.Tis defined in another package, or must the parameter be exactly*testing.T from the standard library?
💡 Result:
No. go test discovers and executes test functions only when they have the required signature using *testing.T (i.e., func TestXxx(t *testing.T)). It does not accept func TestXxx(t *core.T) where core.T is defined in another package, unless that parameter is exactly (not just structurally similar) *testing.T. Authoritative basis: - The testing package documentation defines the test function form as func TestXxx(*testing.T). - The go test command help text (implementation source) similarly states the required signature func TestXxx(t *testing.T). Practical implication: - If your test function has a different parameter type (e.g., *core.T), go test will not treat it as a valid test function, or it will error due to a “wrong signature” (depending on the exact situation), because the runner expects func(*testing.T). If you want to add extra methods/checks while keeping *testing.T as the parameter, you can define a wrapper type and convert/cast from *testing.T to your wrapper around that same pointer (pattern discussed in community sources), but the top-level test function must still accept *testing.T.

Test functions will not be discovered by the standard Go test runner.
The test functions use func TestAX7_…(t *core.T) which does not match the required signature func TestXxx(t *testing.T) from the standard library. The go test command will not discover these functions, so they will never execute. This pattern repeats throughout the file. Additionally, the symbol variable is assigned but never used—core.AssertContains only compares the two string literals, making the assertions tautological and ineffective at validating the metadata they claim to check.

WalkDir errors are still being swallowed in the callback.
Line 194 returns nil when walkErr is non-nil, so traversal failures are ignored and discovery may silently return partial results.

Does go testdiscoverfunc TestXxx(t *core.T)whencore.Tis defined in another package, or must the parameter be exactly*testing.T from the standard library?
💡 Result:
No. go test only discovers and runs TestXxx functions whose signature is exactly func TestXxx(t *testing.T) (i.e., a single parameter whose type is *testing.T from the standard library testing package). If you change the parameter type (e.g., *core.T from another package), the function is not registered as a test and will not be run. Evidence: - The testing package documentation states that go test automates execution of functions of the form func TestXxx(*testing.T). - The Go tool’s test loader checks the function signature during parsing and reports “wrong signature … must be: func TestXxx(t *testing.T) …” if it doesn’t match. You can, however, accept *testing.T and then adapt it to your own type inside the test (e.g., by converting t to a custom type with the same underlying structure, as commonly done with (*myT)(t) where type myT testing.T).

Test functions must use *testing.T parameter for Go test discovery.
The function signature uses *core.T instead of *testing.T. The go test command only discovers and runs TestXxx functions with the exact signature func TestXxx(t *testing.T) from the standard library testing package. With *core.T, these functions will not be registered as tests and will not be run by the test runner, making them ineffective as actual tests.

Does go testdiscoverfunc TestXxx(t *core.T)whencore.Tis defined in another package, or must the parameter be exactly*testing.T from the standard library?
💡 Result:
No, go test does not discover func TestXxx(t *core.T) where core.T is defined in another package. The parameter must be exactly *testing.T from the standard library. The official Go documentation and source code confirm that test discovery requires the precise signature func TestXxx(*testing.T). The go tool parses the AST of test files and checks for *testing.T specifically (via isTestFunc function, which verifies the type name "T" from the "testing" package).

Test function signatures must match the standard Go test signature.
The test functions use func TestXxx(t *core.T), but the Go test runner specifically requires func TestXxx(t *testing.T) from the standard library. These functions will not be discovered or executed by go test. Additionally, the AssertContains calls compare hard-coded strings rather than testing the actual symbol value, making the tests ineffective even if they ran.

Do not turn parent-FD close failures into a leaked child process.
Line 764 folds closeFiles(...) into err after os.StartProcess. If the spawn succeeded but one of those parent-side closes fails, this branch returns an error without tearing the already-running subprocess down.

- process, err := os.StartProcess(path, append([]string{command}, args...), &os.ProcAttr{

In `@mlxlm/backend.go` around lines 760 - 767, The code currently folds
closeFiles(...) into err immediately after os.StartProcess, which can return an
error from closing parent FDs while the child (process variable from
StartProcess) may have started and thus be leaked; change the logic in the
StartProcess block so you first check startErr := err from os.StartProcess
separately, and if startErr == nil then call closeErr := closeFiles(stdinRead,
stdoutWrite, stderr); if closeErr != nil then call process.Kill() and
process.Wait() (or Wait to reap) and return a joined error combining
core.E("mlxlm.process","start "+command, closeErr) plus any additional
closeFiles(stdinWrite, stdoutRead) cleanup; only when startErr != nil return the
original startErr joined with closeFiles(stdinWrite, stdoutRead) as before.
Ensure you reference the process variable returned by os.StartProcess, the
closeFiles(...) calls, and the error construction via
core.E("mlxlm.process","start "+command, ...) so the child is terminated and
reaped if parent-side close fails.

AssertContains checks are tautological and currently add no test signal.
Each call compares hard-coded strings, so these assertions pass regardless of symbol representation. If the intent is symbol-presence only, keep AssertNotNil; if intent is metadata/name validation, assert against a value derived from symbol.

In Go's os/exec package, for exec.CommandContext: what does cmd.Wait() return when the context is cancelled, and is checking ctx.Err() after calling cancel() a reliable way to detect non-cancellation process errors?
💡 Result:
When the context is cancelled for exec.CommandContext, cmd.Wait returns an error indicating the process was killed, typically "signal: killed" or a *exec.ExitError with a non-zero exit status reflecting the termination signal (e.g., exit code -9 for SIGKILL on Unix). It does not return the context's error (context.Canceled) directly. This is because the implementation calls the process's Kill method via the Cancel func when ctx.Done, waits for the process to exit, and returns the process exit error if present; only substituting ctx.Err if the process exited successfully (zero status) after cancellation. Checking ctx.Err after calling cancel (or after Wait) is a common but not fully reliable way to detect cancellation vs. non-cancellation process errors. It works as a heuristic: if ctx.Err != nil and Wait returned a signal/terminated error (not e.Exited for normal exit), assume cancellation caused the kill. However, it has races—e.g., external kill followed by late cancel makes ctx.Err non-nil but not cancellation-caused; or process error before cancel. Sources recommend checking both: if err != nil, type-assert to *exec.ExitError, check !e.Exited && ctx.Err != nil to infer cancellation (with caveats). For precision, use Start/Wait pattern and check ctx before/after, but no perfect distinction exists without custom Cancel func returning ctx.Err.

ctx.Err() check is ineffective due to cancellation order
Calling cancel() on line 60 before cmd.Wait() on line 61 makes the condition ctx.Err() == nil always false. This silences the error diagnostic, preventing visibility of genuine process-exit failures that occur before user-initiated cancellation.
The intent of the check—distinguishing a process error from a cancellation-triggered termination—is lost. Process errors will be suppressed.
Suggested fix
+ waitCh := make(chan error, 1)
+ go func() {
+ waitCh <- cmd.Wait()
+ }()
defer func() {
- cancel()
