Inline comments:
In @.github/workflows/ci_rust.yml:
- Around line 161-164: Update the CI step ordering so the Codecov coverage
upload executes before the daemon transport benchmark smoke check, preserving
the existing platform conditions and commands. Use the “Run daemon transport
benchmark smoke check” and coverage upload steps as the anchors; do not
otherwise alter the workflow.
In `@ATTRIBUTIONS-Rust.md`:
- Line 18307: Add blank lines immediately after the attribution headings “## h2
- 0.4.19” and “## hyper - 1.11.1” in ATTRIBUTIONS-Rust.md at lines 18307-18307
and 20276-20276, respectively.
In `@crates/cli/src/commands/daemon.rs`:
- Around line 273-275: Update the host validation around the unspecified-address
guard to parse the host as an IP address and reject any address where
is_unspecified() is true, covering both IPv4 0.0.0.0 and IPv6 :: while
preserving the existing daemon-target error behavior.
- Around line 146-150: Resolve the unreachable validation around DaemonCommand
by either removing the command/pass_through guard in execute or disabling
args_conflicts_with_subcommands, according to the intended CLI behavior. Ensure
the chosen configuration allows the intended --pass-through handling for daemon
subcommands without retaining dead validation.
In `@crates/cli/src/daemon/broker/server.rs`:
- Around line 2190-2192: Update the TLS accept loops around the broker listener
at crates/cli/src/daemon/broker/server.rs:2190-2192 and worker listener at
crates/cli/src/daemon/worker/runtime.rs:399-400: handle accept errors by
logging, briefly sleeping, and continuing; discard set_nodelay failures instead
of propagating them, so transient connection errors do not terminate either
loop.
- Around line 1233-1244: Prevent configured or environment provider credentials
from being injected when the destination is a client-named upstream
(`NamedUpstream::Named`), or validate such destinations against approved
provider origins before injection. Apply the same guard to the forwarding paths
in crates/cli/src/daemon/broker/server.rs at lines 1233-1244,
crates/cli/src/daemon/worker/managed.rs at lines 740-745, 547-553, and 585-598,
and the managed-worker path in crates/cli/src/daemon/worker/runtime.rs at lines
644-653; preserve credential injection for approved non-named destinations.
In `@crates/cli/src/daemon/common/address.rs`:
- Around line 49-53: Update both unspecified-address guards in
crates/cli/src/daemon/common/address.rs:49-53 and
crates/cli/src/daemon/common/address.rs:97-101 to parse the host as IpAddr and
use is_unspecified(), covering IPv4 and IPv6 wildcard addresses while preserving
the existing daemon-target and advertise-address errors.
- Around line 24-27: Preserve the explicit-port detection using http::Uri and
http::uri::Authority::port_u16 in the raw address parsing flow. Do not replace
it with Url::port(), so explicitly written default ports such as HTTP 80 and
HTTPS 443 remain accepted.
In `@crates/cli/src/daemon/common/client.rs`:
- Around line 379-395: Update retry_control to replace fixed retry_delay waits
with capped exponential backoff plus jitter, while preserving total_timeout and
attempt_timeout limits. Retain response metadata from operation and, when a 503
includes Retry-After, use that duration for the next retry, bounded by the
overall deadline. Keep immediate returns for successful and non-transient
failures, and add a zero-delay guard only if policy permits zero delays.
In `@crates/cli/src/daemon/common/routes.rs`:
- Around line 65-72: Update the provider path construction around
normalize_openai_path so Anthropic base URLs ending in /v1 are normalized too,
preventing duplicated /v1 segments while preserving existing OpenAI behavior.
Rename the helper to a provider-agnostic name such as normalize_v1_path and use
it for both provider branches; consolidate the double match self logic to avoid
cloning path_and_query twice.
In `@crates/cli/src/daemon/common/state.rs`:
- Around line 199-221: Update the async recover_worker and ready_worker handlers
to execute the complete ActiveWorkerGenerations transaction, including matches,
publish, revoke_if_matches, and restore_if_matches, inside
tokio::task::spawn_blocking and await its result. Ensure all synchronous file
I/O and lock acquisition occur within the blocking task while preserving the
existing transaction outcomes and error propagation.
In `@crates/cli/src/daemon/common/transport.rs`:
- Around line 273-282: Centralize daemon pool configuration: in
crates/cli/src/daemon/common/transport.rs lines 273-282, export pooled_builder
for worker_tls; in crates/cli/src/daemon/common/worker_tls.rs lines 242-249,
replace the duplicated builder setup with pooled_builder(); in worker_tls.rs
lines 25-27, remove the local CONNECT_TIMEOUT and MAX_IDLE_CONNECTIONS_PER_HOST
constants and reuse transport definitions; in transport.rs lines 254-271,
extract shared pooled-client connector setup into a private helper used by
pooled_client and pooled_worker_h2c_client, leaving only http2_only(true) as the
latter’s distinction.
- Around line 252-254: Correct the documentation for pooled_worker_h2c_client to
describe its production use in the cleartext_h2c worker pool and its requirement
that loopback cleartext workers support HTTP/2 prior knowledge because the
client enforces http2_only(true). Remove the claim that it exists only for
deterministic end-to-end transport tests, while leaving the implementation
unchanged.
- Line 219: Update the provider URL validation around https_or_http to reject
non-loopback http:// URLs during configuration, while continuing to allow
loopback HTTP endpoints; ensure provider credentials are never sent over
off-host cleartext connections.
In `@crates/cli/src/daemon/common/worker_tls.rs`:
- Around line 138-142: Update the advertised_host validation near the existing
empty and 0.0.0.0 check to parse the normalized value as an IpAddr, reject
IPv4/IPv6 unspecified addresses (including ::), and reject multicast or
otherwise non-concrete address forms while preserving the existing
CliError::Config response.
In `@crates/cli/src/daemon/hook/mod.rs`:
- Around line 136-151: Update hook_endpoint in the Rust daemon hook flow to
validate the daemon address through crate::daemon::common::address::daemon_url
before any credential-bearing request, rejecting remote HTTP endpoints while
preserving valid daemon URL handling. Also update readDeploymentConfig in
crates/cli/src/daemon/managed/pi_extension/index.ts: permit HTTP only when the
hostname is localhost or a loopback IP, and reject all other HTTP hosts before
sending x-nemo-relay-client-token.
In `@crates/cli/src/daemon/managed/mod.rs`:
- Around line 899-918: Refactor all_artifact_paths and the render_codex,
render_claude, and render_pi functions to share a single
artifact_paths_for(agent) source of truth. Have each renderer use its
corresponding static path slice when constructing artifacts, and derive
all_artifact_paths from those shared slices so rendered paths and validation
remain identical.
- Around line 752-754: Update toml_string so it cannot be mistaken for a general
TOML encoder: either rename it to reflect that it only quotes validated ASCII
values, or add an explicit assertion enforcing its ASCII-only precondition.
Preserve the existing callers’ output while preventing future arbitrary or
non-ASCII values from being passed silently.
In `@crates/cli/src/daemon/managed/pi_extension/index.ts`:
- Around line 320-323: Update the quit handling to resolve the existing runtime
or active lease without calling runtime(), thereby avoiding ensureReady and any
MCP relaunch before release. Preserve the existing active.lease.release()
behavior once the already-created runtime is obtained.
In `@crates/cli/src/daemon/mcp/mod.rs`:
- Around line 361-372: Update the LaunchWorker wait loop to avoid repeatedly
calling refresh_registration after each 100 ms delay, which re-runs the full
registration handshake; reuse broker-directed retry pacing like WaitForWorker or
poll a lightweight readiness/status endpoint while preserving the existing
activation timeout and launch behavior.
In `@crates/cli/src/daemon/worker/managed.rs`:
- Around line 1248-1252: Add a body-level deadline to
ObservationReceiver::finish/finish_buffered covering both receiver.recv() and
ObservationSignal::wait(), using the established response timeout configuration
where appropriate. When the deadline expires, record the observation as failed
and ensure the observation task completes so llm_call_end still runs.
In `@crates/cli/src/daemon/worker/mod.rs`:
- Around line 72-78: Update the worker TLS initialization around
WorkerTlsIdentity::generate to replace the expect on options.advertise_address
with an early return of CliError::Unauthorized when the bind address is
unspecified and no advertise address is provided; preserve the existing
generation path when the address exists.
In `@crates/cli/src/gateway/mod.rs`:
- Around line 88-95: Update the managed-client branch in the gateway match
around client_named_upstream_url so authenticated daemon traffic cannot select
an arbitrary authority before inject_provider_auth applies credentials. Disable
the named-upstream override for managed traffic, or enforce that the selected
scheme and host match the configured provider before accepting
Named(destination); preserve the existing rejection and provider.upstream_url
fallback behavior.
In `@crates/cli/src/mcp/session.rs`:
- Around line 36-47: Refactor run to compose run_without_gateway with the lease
wait, matching the existing serve_with_lease pattern instead of duplicating the
frame-processing loop. Preserve the current behavior by selecting between the
complete run_without_gateway future and lease.wait(), including the existing
lease-expiration handling.
In `@crates/cli/tests/architecture_tests.rs`:
- Around line 628-632: Update the assertion for visitor.violations to verify the
six expected rule identities, rather than only checking violations.len() >= 5:
aliased to_bytes, collect, extend_from_slice, Vec::new, Body::from_stream, and
SseEventDecoder. Preserve the fixture execution and ensure the assertion fails
if any individual rule stops firing.
- Line 142: Update the architecture visitor’s “collect” rejection to apply only
when the call is within an awaited expression, while preserving rejection of
awaited body.collect() calls in the existing fixture. Add the required
await-depth tracking to the visitor, then remove obsolete allowlist exceptions
that no longer trigger; keep unrelated iterator .collect() calls accepted.
- Around line 591-596: Update the architecture test’s monitored-module discovery
around the existing relative-path loop to derive daemon streaming modules from
the streaming type rather than hardcoding four paths. Ensure the derived set
includes registry, worker control, and hook modules when applicable, preserves
the trailing non-empty discovery assertion, and aligns allowlist keys with the
derived daemon/... relative paths.
In `@crates/cli/tests/cli_tests.rs`:
- Line 5672: Replace the unbounded Command::output calls in the daemon mcp and
daemon worker test cases with the existing wait_child_with_output helper,
preserving the current command arguments and assertions, including the
unattached worker failure check.
- Around line 5431-5444: Wrap the spawned MCP process in the existing ChildGuard
pattern so panics during the test cannot leak the process or its worker. Update
the pre-shutdown stdin and stdout operations to access the guarded child, then
add or reuse a ChildGuard release operation at the graceful-shutdown assertion
to recover ownership without changing that assertion’s behavior.
In `@crates/cli/tests/coverage/commands/daemon_tests.rs`:
- Line 26: Update each failure case in the daemon command tests to assert the
specific bind-validation error returned by execute, rather than only checking
is_err(), so connection failures cannot satisfy the test. In the worker case,
remove the redundant worker.bind assignment because command already sets the
value; keep the subcommand bind as the cause of rejection.
- Around line 26-39: Strengthen the daemon bind-contract tests by asserting the
specific error text or variant returned by execute instead of only checking
is_err(). In crates/cli/tests/coverage/commands/daemon_tests.rs:26-39, update
all three cases and remove the redundant worker.bind assignment; in
crates/cli/tests/coverage/commands/main_tests.rs:703-725, update both the server
and worker cases to match the bind-validation error.
In `@crates/cli/tests/coverage/commands/integrations_tests.rs`:
- Around line 84-87: Update both EnvScope::set calls in
crates/cli/tests/coverage/commands/integrations_tests.rs at lines 84-87 and
101-102 to also override HOME and USERPROFILE with the temporary directory, or
use the existing hermetic scope helper, so refresh_targets(None) performs
discovery without consulting the real user profile.
In `@crates/cli/tests/coverage/commands/main_tests.rs`:
- Around line 752-756: Update the test around daemon::execute to verify the
expected codex and pi artifact entries are present, rather than only checking
that the output directory is non-empty. For each generated artifact, inspect its
metadata and assert it has read-only permissions, preserving the successful
ExitCode assertion.
In `@crates/cli/tests/coverage/daemon/client_tests.rs`:
- Around line 43-48: Strengthen both tests in
crates/cli/tests/coverage/daemon/client_tests.rs:43-48 and
crates/cli/tests/coverage/daemon/client_tests.rs:237-241. For the
oversized-response test, have the mock send an oversized first frame and record
whether a second frame is requested, then assert polling stops after the limit
is exceeded. For the role-rejection test, assert the expected role-rejection
message rather than only matching the CliError::Config variant.
In `@crates/cli/tests/coverage/daemon/control_tests.rs`:
- Around line 140-150: Extend
worker_generation_grant_binds_endpoint_and_tls_root to assert that verification
fails when the TLS root is substituted and when tls_root_certificate is omitted,
while keeping the existing endpoint-substitution assertion and valid
verification coverage unchanged.
In `@crates/cli/tests/coverage/daemon/hook_tests.rs`:
- Line 43: Update capture_server’s response write to tolerate BrokenPipe and
ConnectionReset when the client abandons the connection, while preserving
failures for other I/O errors. Ensure server.join().unwrap() can complete so the
oversized-response assertion runs.
In `@crates/cli/tests/coverage/daemon/managed_tests.rs`:
- Around line 49-51: Update the version scan in the managed-tests loop to
exclude the pi/extension-v1/package.json artifact, or assert only the intended
version placeholders. Preserve validation for all other generated files and
avoid treating its fixed 1.0.0 manifest as the crate version.
In `@crates/cli/tests/coverage/daemon/mcp_tests.rs`:
- Around line 153-170: The test
remote_daemon_derives_a_concrete_non_loopback_worker_advertisement must not
panic when worker_network_hint cannot connect due to a runner without an
outbound IPv4 route. Handle the expected connection error by gating the test or
treating that error as an acceptable outcome, while preserving the existing
assertions when a hint is successfully derived.
In `@crates/cli/tests/coverage/daemon/protocol_tests.rs`:
- Around line 36-37: Update the fixture constructing the registration transcript
so initiator_nonce and responder_nonce use distinct nonce values, while
preserving the expected request and challenge relationships required by
validate_registration. Ensure both_participants_sign_the_same_transcript and
any_signed_field_mutation_invalidates_the_proof exercise independent nonce
positions.
- Around line 129-132: Update ComponentDescriptor::validate to return
ProtocolError::MissingBinaryVersion only for an empty binary_version and
ProtocolError::BinaryVersionTooLong when it exceeds MAX_BINARY_VERSION_BYTES;
add the distinct error variant and ensure validate_registration/control_error
propagate it unchanged.
In `@crates/cli/tests/coverage/daemon/registry_tests.rs`:
- Around line 396-404: Update the test
expired_launch_owner_is_transferred_idempotently to call expire_mcp_leases a
second time with the same timestamp after validating the initial transfer, then
assert that the second call returns no actions.
In `@crates/cli/tests/coverage/daemon/routes_tests.rs`:
- Around line 42-49: Extend the ProviderRoute::Anthropic.upstream_url test
coverage with a base URL lacking a trailing slash, verifying the path joins with
exactly one separator. Also add a base URL ending in /v1 and assert it is
preserved without OpenAI-style normalization.
In `@crates/cli/tests/coverage/daemon/state_tests.rs`:
- Around line 283-298: Update the too_many payload in the oversized-generation
test to assign a distinct fingerprint to each of the
MAX_ACTIVE_WORKER_GENERATIONS + 1 entries, using a seed representation wide
enough if the limit can exceed 255. Keep the route-count assertion and all other
test behavior unchanged so the fixture isolates the route-limit validation.
In `@crates/cli/tests/coverage/daemon/worker_runtime_tests.rs`:
- Around line 152-161: Update the duplicate header setup in the test to
construct the HeaderMap and add both WORKER_TOKEN_HEADER values using explicit
append calls, rather than HeaderMap::from_iter. Preserve the duplicate values
and existing test behavior.
In `@crates/cli/tests/coverage/daemon/worker_tests.rs`:
- Around line 34-42: Extend worker_network_must_match_activation_grant with
assertions covering a bind-address mismatch between options.bind and
bootstrap.bind_ip, plus a case where advertise_address is set and
validate_bootstrap checks the advertised socket. Keep the existing port-mismatch
error assertion and verify the new cases’ expected validation outcomes.
In `@crates/cli/tests/coverage/shared/config_tests.rs`:
- Around line 476-480: Update the test’s system plugin fixture and user
lifecycle state so at least one dynamic-plugin component is declared, while the
user state disables or alters that component; then assert the component remains
active. Replace the current empty-list assertion with an assertion that
distinguishes ignored user state from having no configured components, using the
existing active_dynamic_plugin_components flow.
In `@crates/cli/tests/coverage/shared/doctor_tests.rs`:
- Around line 315-325: Add a duplicate-header validation case to the ATOF header
validation tests near the existing endpoint_headers success case, declaring the
same header name in both headers and header_env and asserting the documented
rejection. Preserve the existing distinct-header success assertion and cover the
activation-time duplicate detection behavior.
- Around line 9-15: Serialize all tests that mutate process-global environment
variables by acquiring PLUGIN_CONFIG_TEST_LOCK before EnvScope::set. Apply this
in crates/cli/tests/coverage/shared/doctor_tests.rs at lines 9-15, 44, 87, 615,
and 645, and in crates/cli/tests/coverage/shared/config_tests.rs at lines
402-433 and 486, covering the PI, ROUTE_TOKEN, XDG_CONFIG_HOME, and NEMO_RELAY_*
variables.
In `@crates/cli/tests/coverage/shared/gateway_tests.rs`:
- Around line 1896-1905: Remove the duplicate assertion invoking
gateway_upstream_url_override_with_openai_key_state for
ProviderRoute::OpenAiResponses and the /backend-api/codex/responses path; keep
the equivalent coverage in chatgpt_backend_url_omits_v1_prefix.
- Around line 1926-1935: Update daemon_provider_upstream_url and the subsequent
inject_provider_auth flow so caller-selected UPSTREAM_BASE_URL_HEADER HTTPS
origins cannot receive administrator OpenAI credentials; reject such origins
when no caller provider credential is supplied, or enforce the existing
administrator origin allowlist. Add coverage confirming administrator
credentials are never sent to a caller-selected origin while preserving valid
ChatGPT override behavior.
In `@crates/cli/tests/coverage/shared/plugin_prompt_tests.rs`:
- Around line 197-207: Update the test around edit_selected_value_item so the
no-default case uses index == schema.fields.len(), allowing the reset branch to
execute without a default. Adjust the expected return value and post-state
assertions to match the documented contract for resetting when default is None,
while preserving the existing out-of-range coverage separately.
In `@crates/cli/tests/coverage/shared/plugins_lifecycle_tests.rs`:
- Around line 36-38: Update the runner invocations in the lifecycle test to pass
bare program names, such as “true” and “false”, instead of hard-coded `/usr/bin`
paths, so `Command::new` resolves them through PATH while preserving the
existing success and exit-status assertions.
In `@crates/cli/tests/managed_pi_extension_tests.mjs`:
- Line 13: Add stateful lifecycle tests in the managed Pi extension suite
covering createSharedLease ready, restart, and release transitions,
session_shutdown reason branches, and hookQueue observeOrdered ordering. Use a
fake dispatcher script to exit the MCP child, dispatch session_shutdown with
reason quit, and assert lifecycle events show no new process is started during
shutdown; prefer lifecycle and ordering assertions over shallow helper checks.
In `@docs/nemo-relay-cli/daemon.mdx`:
- Around line 430-431: Update the managed-bundle doctor documentation near
collect_managed_bundle_report to remove the claim that it checks the managed
credential environment, keeping the description consistent with
run_managed_bundle_doctor and its current diagnostics.
- Line 150: Update the table’s product name from “pi” to “Pi” while preserving
lowercase “pi” only where it appears in the literal command `nemo-relay daemon
hook pi`.
In `@justfile`:
- Line 1229: Update the daemon-transport-benchmark-smoke recipe to resolve and
use the configurable output_dir, matching the neighboring latency-benchmark
recipe’s fallback to target/benchmark-results; replace the hardcoded smoke
report directory while preserving the existing output filename.
In `@scripts/latency_benchmark/daemon_transport/Cargo.toml`:
- Around line 10-11: Add explicit CI/pre-commit commands for the detached
workspace manifest: run cargo fmt and cargo clippy --all-targets -- -D warnings
against its Cargo.toml. Keep the existing nested Cargo.lock and Rust
1.96.1-compatible configuration unchanged.
In `@scripts/latency_benchmark/daemon_transport/src/client.rs`:
- Around line 589-590: Ensure each request uses a single ordinal for both
cancellation selection and stream ID construction. Update the request flow
around run_slow_scenario and perform_request to pass the already-drawn
request_sequence ordinal into perform_request, removing the second increment;
alternatively, maintain a separate counter exclusively for stream_id.
In `@scripts/latency_benchmark/daemon_transport/src/config.rs`:
- Around line 326-329: Update TargetSpec validation around the URI scheme check
to reject plain-http targets when TargetHeader credential bindings are present,
except when the authority is loopback. Preserve HTTPS behavior and allow
loopback HTTP targets, while continuing to reject unsupported schemes.
In `@scripts/latency_benchmark/daemon_transport/src/main.rs`:
- Line 116: Update the setup flow around WorkerHarness::add_to so that an add_to
error invokes WorkerHarness::shutdown() before propagating the error. Preserve
the existing successful path and ensure shutdown performs the needed MCP
release, worker-exit wait, and proxy-task cleanup.
In `@scripts/latency_benchmark/daemon_transport/src/orchestrate.rs`:
- Around line 391-399: Update proxy_control_request and
proxy_control_request_inner to distinguish validation rejections from capture
failures: return the appropriate rejection response for non-POST requests and
disallowed paths without calling fail_capture or modifying capture state. Remove
the now-redundant ensure checks that classify these validation cases as
failures, while preserving fail_capture for genuine control-plane errors.
In `@scripts/latency_benchmark/daemon_transport/src/provider.rs`:
- Around line 182-185: Refactor the event formatting helpers so `make_event`
delegates to a new `write_event(&mut String, ...)`; use one reusable buffer when
computing `base_size` in `stream_response` instead of allocating a new event for
each measurement, while preserving identical output and length calculations for
the emitted stream body.
- Line 238: Bound the response_bytes value parsed by header_number in the
provider response handling, using an upper limit consistent with the existing
event_count validation before it reaches remaining, padding, and the "x".repeat
allocation. Preserve the existing parsing behavior for valid bounded values.
In `@scripts/latency_benchmark/daemon_transport/src/resources.rs`:
- Around line 81-82: Clarify the semantics of average_cpu_percent in the
aggregation around aggregate.cpu_samples and the Linux ps %cpu collection path:
rename the field to indicate lifetime-average CPU usage, or add explicit
documentation that it is not benchmark-window CPU usage, especially for
load-driver and externally supplied long-running PIDs. Do not present the
averaged values as in-window usage unless you replace them with Linux
/proc/<pid>/stat utime/stime deltas.
- Around line 122-125: Wrap the `ps` process await in the sampler around
`Command::new("ps")` with `tokio::time::timeout`, using the established process
timeout configuration. Handle timeout expiry like the existing spawn-failure
path so sampling returns without blocking `finish`/`update` and emits the same
diagnostic behavior.
- Line 50: Configure the interval created in the sampler flow around
tokio::time::interval with an explicit missed-tick behavior of Delay or Skip,
preventing slow update calls from triggering back-to-back sampling. Preserve the
existing one-second interval and update behavior.
In `@scripts/latency_benchmark/README.md`:
- Line 15: Update the cross-reference wording beginning at “measurements. See”
to use “refer to” instead, preserving the referenced resource and surrounding
documentation.

Inline comments:
In @.github/ci-path-filters.yml:
- Line 168: Retain crates/cli/assets/** in the rust filter of the CI path
configuration so asset-only changes trigger Rust checks, including include_str!
embedding and EXTENSION_FILES tests; do not rely on the pi filter as a
replacement.
In `@ATTRIBUTIONS-Rust.md`:
- Line 18307: In the attribution sections headed by “## h2 - 0.4.19” and the
other reported heading, insert one blank line between each heading and its
following “**Repository URL**” line to satisfy Markdown heading-spacing rules.
In `@crates/cli/src/commands/daemon.rs`:
- Around line 267-276: Update parse_daemon_address to strip surrounding IPv6
brackets from host before the unspecified-address and loopback checks, then
parse the normalized value in both IpAddr calls while preserving localhost
handling.
In `@crates/cli/src/daemon/broker/registry.rs`:
- Around line 343-347: Update the transient branch in mark_activation_failed to
transition RouteState::PassThrough { permanent: false } into a bounded retry
state instead of indefinitely preserving pass-through while references remain.
Ensure directive_for, current_directive, and after_reference_removed honor the
retry transition and eventually re-enable managed-worker enforcement, while
keeping permanent pass-through unchanged.
In `@crates/cli/src/daemon/broker/server.rs`:
- Line 1966: Move calls to revoke_active_worker_generation and
revoke_worker_generation out of Tokio async runtime threads by wrapping each
blocking operation in tokio::task::spawn_blocking, including the maintenance
task and the ReleaseAction::BeginDrain flow. Preserve the existing sequencing,
awaiting the blocking task before continuing with drain handling where required.
In `@crates/cli/src/daemon/hook/mod.rs`:
- Line 20: Update HOOK_FORWARD_TIMEOUT to align with the managed Pi client's
30-second authorization budget, or explicitly document and enforce the intended
stricter limit across the managed hook path. Ensure asynchronous
tool_conditional_execution guardrails can complete before
handle_delivery_failure is triggered, preserving the expected HookFailurePolicy
behavior.
In `@crates/cli/src/daemon/mcp/mod.rs`:
- Around line 333-342: Update the try_wait exit-handling branch around launched
and report_activation_failed to require the same launched-activation identity
check used by the timeout branch before reporting against
bootstrap.activation_id. Preserve stale child state and avoid clearing or
dropping the Child handle; only report and refresh when the exited child belongs
to the current activation.
In `@crates/cli/src/daemon/mod.rs`:
- Around line 26-28: Validate daemon listener configuration so any public bind
address, including 0.0.0.0, is rejected unless both tls_cert and tls_key are
configured. Preserve non-TLS support for non-public listeners and use the
existing daemon configuration validation or startup path.
In `@crates/cli/src/daemon/worker/managed.rs`:
- Around line 440-454: Update the llm_call error path in proxy_managed to invoke
self.sessions.finish_gateway_call(&session_id, session_finish) before
propagating the error, matching the existing failure handling in
proxy_unbuffered and the other proxy_managed branches. Preserve the current
successful result handling.
In `@crates/cli/src/daemon/worker/mod.rs`:
- Around line 73-78: Validate advertise_address before passing it to
WorkerTlsIdentity::generate, rejecting values that include a port while
accepting valid hostname and IPv4/IPv6 host forms. Ensure
worker_advertised_address receives only the host component so it appends the
local port correctly, and preserve the existing Unauthorized error path for
missing addresses.
In `@crates/cli/src/daemon/worker/runtime.rs`:
- Around line 259-283: Update wait_until_stopped to create/register the
lifecycle.notified() future before loading exiting, draining, or other state,
matching ObservationSignal::wait. Await the pre-registered notification in both
the non-draining and draining paths while preserving the existing exit,
in-flight, and deadline checks.
In `@crates/cli/tests/architecture_tests.rs`:
- Line 597: Normalize the path separators in the relative value created by
strip_prefix before it is compared with the allowlists. Update the architecture
test path handling around allows_request_body_decode and allows_sse_observation
so Windows backslashes become forward slashes, preserving the existing literal
allowlist entries and behavior on other platforms.
In `@crates/cli/tests/cli_tests.rs`:
- Line 5600: Update the MCP shutdown wait around wait_child_with_output so it
uses an explicit timeout longer than CHILD_PROCESS_TIMEOUT_SECONDS,
accommodating coverage-instrumented process teardown while preserving the
existing output collection and timeout failure behavior.
In `@crates/cli/tests/coverage/daemon/control_tests.rs`:
- Around line 70-72: Extend the WorkerBootstrap::from_directive conversion test
to assert that deadline_unix_ms and bind_ip match the directive’s input values,
alongside the existing activation and port assertions.
In `@crates/cli/tests/coverage/daemon/lifecycle_tests.rs`:
- Around line 41-48: Expand the lifecycle validation tests around
WorkerTarget::new and WorkerTarget::with_shared_client to cover empty worker IDs
and endpoints, asserting each returns LifecycleError::EmptyIdentifier. Add an
empty-token case for SensitiveString::new and assert the exact
ProtocolError::MissingSensitiveValue variant, while retaining the existing
non-empty validation.
In `@crates/cli/tests/coverage/daemon/managed_tests.rs`:
- Around line 510-518: Update the test loop around write_new_bundle and
refresh_bundle so the renamed .original file is placed outside the bundle root,
leaving only the symlink inside it; then assert that refresh_bundle returns the
expected symlink rejection rather than an unexpected-artifact error.
In `@crates/cli/tests/coverage/daemon/protocol_tests.rs`:
- Around line 63-69: Extend
capability_serialization_and_transcript_order_are_deterministic to build
HandshakeTranscript values with differently ordered capabilities and assert
their canonical_bytes() match. Add mutation checks for every canonical field,
asserting verify() rejects each changed transcript; when a mutation causes
validate() to fail before signature verification, assert the resulting error
with is_err().
In `@crates/cli/tests/coverage/daemon/worker_managed_tests.rs`:
- Around line 1362-1363: Convert the test containing
request_body_decode_required and reject_incompatible_execution_middleware to an
async #[tokio::test], then acquire PLUGIN_CONFIG_TEST_LOCK before reading the
global middleware registry and retain the guard through both assertions.
In `@crates/cli/tests/managed_pi_extension_tests.mjs`:
- Line 70: Replace the fixed 50 ms delay in the managed extension restart test
with polling of the launches file until the second launch is observed, using a
generous timeout. Ensure the test only proceeds to the restart assertion after
the observed launch count confirms the child exited and the lease was
reacquired.
- Around line 22-29: Update the temporary module source-rewrite setup in
managed_pi_extension_tests to use requireReplace for each required pattern
replacement, so a missing lifecycle rewrite fails immediately at module loading
rather than causing a delayed or misleading test failure. Preserve the existing
replacements for initialize, createSharedLease, and the exported installer, and
keep the relative configuration lookup behavior unchanged.
In `@docs/nemo-relay-cli/daemon.mdx`:
- Around line 349-351: Update the runtime test setup near the
observation-capture documentation to clear
NEMO_RELAY_DAEMON_OBSERVATION_CAPTURE_BYTES, replacing the ineffective
NEMO_RELAY_OBSERVATION_CAPTURE_BYTES cleanup so serve initializes with its
default capture bound.
In `@scripts/latency_benchmark/daemon_transport/src/client.rs`:
- Around line 885-886: Update the report construction around reconnect_count and
max_active_http2_streams so field names match their actual measurements:
connections opened during measurement and pool-wide in-flight requests,
respectively. Alternatively, remove these inaccurate values and add the
corresponding metrics to unavailable_metrics, preserving accurate reporting.
In `@scripts/latency_benchmark/daemon_transport/src/config.rs`:
- Line 335: Update the target URL validation around the existing authority check
to reject authorities containing userinfo before constructing or storing the
TargetSpec. Apply this validation unconditionally, including targets without
configured headers, so TargetRecord cannot serialize credentials from
target.url.
In `@scripts/latency_benchmark/daemon_transport/src/metadata.rs`:
- Around line 82-87: Update binary_record to stop executing the user-supplied
BinarySpec path with --version; record only the file’s size_bytes and sha256 as
required by the --binary-metadata contract. Remove the Command::new execution
and version-derived metadata while preserving the existing BinarySpec validation
and metadata output structure.
In `@scripts/latency_benchmark/daemon_transport/src/provider.rs`:
- Line 248: Remove the runtime-only event_count floor in the provider request
path and validate the minimum during matrix configuration deserialization, or
document the required minimum in the provider README. Ensure low client-supplied
matrix.events values fail as diagnosable configuration errors rather than
producing request-time 400 responses; update the event_count validation and the
matrix configuration handling accordingly.

- Line 221: Protect the unauthenticated CHALLENGE_PATH endpoint from slot
exhaustion by adding per-peer rate limiting and reserving challenge capacity for
legitimate registrations before issue_challenge allocates pending challenges.
Preserve worker bootstrap without requiring the MCP route credential unless
workers already possess it, and keep the existing challenge lifetime and 429
behavior for genuinely exhausted capacity.
- Around line 2186-2188: Update activation_endpoint_matches to preserve explicit
default ports when comparing worker endpoints: distinguish an explicitly
specified port from an omitted port and treat explicit 80 for HTTP and 443 for
HTTPS as present. Keep validate_worker_endpoint and matching behavior unchanged
for non-default or omitted ports.
In `@crates/cli/src/daemon/mcp/mod.rs`:
- Around line 317-322: Update the worker activation lifecycle around the
launched Child handle: terminate and await children when activations time out,
are superseded by a different LaunchWorker directive, or exit through
overall-timeout, UsePassThrough, and other error paths. Preserve the child on
the successful ReuseWorker path because kill_on_drop(false) is intentional;
ensure cleanup completes before replacing or returning from the activation flow.
In `@crates/cli/src/daemon/worker/managed.rs`:
- Around line 1267-1269: Update the timeout around finish_inner in the streaming
observation flow so it does not reuse RESPONSE_HEAD_TIMEOUT as the total
stream-draining deadline. Introduce or reuse a separate larger observation
timeout, or enforce an idle-between-frames limit, while preserving successful
completion and response-hint recording for streams that run longer than 60
seconds.
In `@crates/cli/tests/coverage/daemon/address_tests.rs`:
- Around line 42-69: Add assertions for worker_advertised_address with a
concrete local bind, verifying configured advertisements are rejected and no
advertisement returns local.to_string(). Extend the hostname cases to assert
rejection of hosts with labels beginning or ending in '-' and hosts exceeding
253 bytes, while preserving the existing valid hostname and IPv6 coverage.

The unauthenticated handler allocates pending challenges before registration authentication. An attacker can fill the 384 MCP or 128 worker slots for CHALLENGE_LIFETIME_MS, causing legitimate registrations to receive 429. Add per-peer rate limiting and reserve capacity for legitimate registrations. Do not require the MCP route credential for worker bootstrap unless workers have that credential before registration.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Preserve explicit default ports when matching worker endpoints.
validate_worker_endpoint accepts explicit ports 80 and 443 through http::Uri. The MCP carries NEMO_RELAY_WORKER_PORT through WorkerNetworkHint into LaunchWorker. When the worker registers https://host:443 or http://127.0.0.1:80, reqwest::Url::port() returns None, so activation_endpoint_matches can reject the endpoint. register_worker then marks the activation failed.
🐛 Proposed fix
- let (Some(host), Some(port)) = (url.host_str(), url.port()) else {
+ let (Some(host), Some(port)) = (url.host_str(), url.port_or_known_default()) else {
return false;
};📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

worker_command sets kill_on_drop(false) because a worker must remain alive after successful readiness and after make_route_ready returns. Do not kill launched on the normal ReuseWorker path.
When an activation times out or a different LaunchWorker directive replaces it, the existing Child can still own a live worker. Replacing or dropping that handle does not terminate the worker. With NEMO_RELAY_WORKER_PORT set, the worker can keep the fixed listener occupied and cause replacement workers to fail to bind, so route setup can reach ACTIVATION_POLL_MAX.
Terminate and await the previous child before replacing launched. Also clean up the pending child on the overall-timeout, UsePassThrough, and other error exits. Preserve the child on the successful ReuseWorker path.

Do not reuse the response-head timeout as the whole-stream observation deadline.
RESPONSE_HEAD_TIMEOUT is 60 s and bounds only the provider response head in dispatch_observed and dispatch_unbuffered_observed. Line 1267 applies the same 60 s to finish_inner, which drains every captured frame until the body ends. A streaming provider response that lasts longer than 60 s therefore always hits the timeout branch. llm_call_end then records response = Value::Null, otel.status_code = ERROR, and the description provider response observation timed out, and record_gateway_response_hints never runs, even though delivery to the client succeeded.
Long agent completions routinely exceed 60 s. Use a separate, larger observation deadline, or bound idle time between frames instead of total stream duration.
🐛 Proposed direction
+/// Bounds observation completion independently of the response-head deadline. Streaming provider
+/// responses can legitimately exceed the head timeout.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Cover the concrete-bind and hostname-boundary branches.
worker_advertised_address must reject configured advertisements for concrete binds and return local.to_string() when no advertisement is configured. Its hostname validation also rejects labels that start or end with - and hosts longer than 253 bytes. Add these error-path assertions to satisfy the test contract for the changed API.
