layers: close the dev_direction baseline and two domain_dependencies entries - #1694
This closes three layers baseline entries that don't belong to common-core. dev_direction now runs with an empty baseline.
dev_direction, sbx-mgr-store → node-runtime-core: two store tests built execution metadata from node-runtime-core's compiled catalog, an API-layer crate. The store checks a binding's runtime kind against the sandbox row and its environment reference against an upgrade's target, and otherwise compares whole values. So synthetic Firecracker metadata bound to synthetic sha256: references exercises the same checks, and the dev-dependency is gone.
domain_dependencies, net-common → tokio: tokio came only through the optional host-sockets feature. That feature's orig_dst module is generic Linux socket-option code for transparent proxying (IP_TRANSPARENT, IP_RECVORIGDSTADDR, SO_ORIGINAL_DST, SO_MARK, IP_FREEBIND). It moves unchanged into a new Foundation crate, pplx-space-transparent-proxy-socket. net-gateway-client already re-exported orig_dst, and now re-exports it from the new crate, so pplx_space_net_gateway_client::orig_dst keeps working.
domain_dependencies, spaced-guest-protocol → tokio: the timeout overflow check now uses std::time::Instant::now() instead of tokio::time::Instant::now(). Outside a paused test runtime they read the same clock, and the error text is unchanged.
spaced-common's model_protocol and domain_dependencies entries stay. The crate holds both the compiled spaced protos and the UDS/vsock/retry transport, so closing them means splitting it into a protocol crate and a transport crate, which is a larger change.
Feature removed: pplx-space-net-common/host-sockets, and with it the path pplx_space_net_common::orig_dst.
No metric, span, log, wire or SQL text changes.
Validation
cargo fmt --check and cargo check --workspace --all-targets pass.
Feature builds pass for node-runtime-core (host-runtime), net-common (no default features, and all features) and sbx-mgr-store (test-support).
clippy passes on the six touched crates.
ci/scripts/run-rust-checks.sh clippy and isolated-crates pass. cargo arch and ci/scripts/run-archcheck.sh against the base report no required findings.
nextest on the touched crates passes, apart from node-runtime-core's cloud-hypervisor tests, which need root.
tests-unprivileged: 12,424 passed and 41 failed. All 41 are guest-process and node-mgr privileged-path tests in crates this change doesn't touch.
Severity and risk
Severity: does not apply (structural).
Risk: low. Code that enables pplx-space-net-common/host-sockets or imports pplx_space_net_common::orig_dst stops compiling until it uses the new crate. Roll back by reverting.
AI assistance: Claude Code drafted the change and this description.
No actionable comments were generated in the recent review.
Walkthrough
The change adds a transparent proxy socket crate and redirects gateway and Linux runtime socket calls to it. The net common crate removes its host-sockets feature and orig_dst module. Guest protocol timeout validation uses std::time::Instant instead of Tokio. Storage tests construct Firecracker execution metadata directly. Workspace and architecture dependency declarations are updated.

Merge Risk: Low · up to e1488
This is mostly a mechanical crate extraction plus test fixture changes. The one behavior-adjacent change is the clock used to reject oversized readiness timeouts, which should behave the same for any realistic value. Owners should confirm that very large timeouts still return InvalidArgument and that the timeout tests pass under a paused clock.
Security architecture risk: Low · up to e1488
The socket implementations and known privileged callers are preserved, and no new security weakness was demonstrated. The main residual risk is compatibility for consumers of the removed import path; downstream and deployment coverage is incomplete.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The inspected security-relevant scope remains existing gateway transparent-proxy traffic and host-runtime pre-exec sockets. The dependency rewiring does not itself grant an OS capability or introduce a new network endpoint in the compared paths.
Trust Boundaries and Controls
observed — The moved socket implementations are byte-identical to their base versions. Transparent UDP setup still applies IP_TRANSPARENT before binding, original-destination parsing still rejects missing or invalid metadata, and pre-exec socket-option failures still propagate before descriptor handoff. These are preserved controls, not newly added protections.
Resilience and Maintainability Implications
observed — The synthetic fixtures retain assertions for runtime-kind rejection, rollback after cleanup-write failure, target-environment binding, and atomic transition to Booting. Production transaction implementations are unchanged. Upgrade rollback tests still assert restoration of previous metadata, fence release, and rejection of repeated completion; this is source-level coverage, not a reported test-run result.

Full details: Bug Fixes Name A Regression Test
Explanation
The check applies only when the PR fixes a defect in application behavior under crates/, shim/, or ui/. This PR does not fix a defect. The title, description, and objectives describe a layers baseline cleanup: - Three entries are removed from architecture-baseline.toml. - Two store tests switch from compiled-catalog metadata to synthetic fixtures. The node-runtime-core dev-dependency is removed. - The orig_dst module moves unchanged to the new pplx-space-transparent-proxy-socket crate. The host-sockets feature is removed. - Timeout validation in spaced-guest-protocol switches from tokio::time::Instant::now() to std::time::Instant::now(). The author states that the error text and behavior are unchanged. The PR calls this a dependency change, not a fix. The PR reports no metric, span, log, wire, or SQL text changes. No stated objective describes a defect repair. The check does not require a regression test for this PR, so it passes.
Full details: Weakened Safeguards Are Justified
Explanation
The diff weakens no test, lint, CI check, or repository guard without a stated reason. What the diff changes: - Baseline entries (architecture-baseline.toml, 0 added, 9 removed): Removing these entries tightens the layer rules. The [layers.dev_direction] entry, the pplx-space-net-common tokio entry, and the pplx-space-spaced-guest-protocol tokio entry are gone. The pplx-space-spaced-common entries stay, which the description explains. No allowlist entry is added. - Lints: The new pplx-space-transparent-proxy-socket manifest uses [lints] workspace = true, so it inherits workspace lints. No #[allow], #[expect], skip, or ignore attribute appears in the diff. No lint table is loosened. - CI, nextest, deny/clippy config, AGENTS/CLAUDE/CONTRIBUTING, docs/rust, .agents, and CODEOWNERS files: None of these files are in the changed-file list. - Test changes in sbx-mgr-store: One assertion is removed from runtime_upgrades/tests.rs: assert_eq!(target.environment(), Some(target_definition.reference())). The test now builds synthetic Firecracker metadata and attaches the target reference by construction. The author's stated reason is that the removed check compared a catalog target with its own definition reference, which becomes tautological with synthetic fixtures. The description gives a specific reason for the swap: the store checks runtime kind, environment reference, and whole values, and synthetic sha256: metadata exercises the same checks. A doc comment added above environments() also explains the target reference. The execution_binding.rs change removes no assertion. It replaces catalog-derived metadata with a synthetic kernel component and environment digest. - Timeout validation (validate.rs): The overflow check changes from tokio::time::Instant::now() to std::time::Instant::now(). This is not a test or guard removal. The description states the reason and that the error text is unchanged. - orig_dst move and host-sockets feature removal: This is a relocation. The module content is unchanged (R100 renames). It removes a feature flag, which is not a safeguard. Caveat: the reason for the removed runtime-upgrade assertion is fully explained in the PR comments. The description and the code doc comment give a reasonable but less direct justification for that one assertion. The check accepts the description-level reason, so this does not change the verdict.
Full details: Agent Tooling Runs No New Commands
Explanation
The check covers agent plugin manifests, SKILL.md files, command/skill files, and guideline files. PR #1694 (perplexityai/SPACE, author ac-pplx) changes none of these. The changed-file inventory has 23 entries, all Rust sources, Cargo manifests, Cargo.lock, or architecture-baseline.toml. A path search for plugin.json, plugin.yaml, SKILL.md, .claude, skills/, commands/, hooks, MCP, LSP, CLAUDE.md, AGENTS.md, and guideline files matched nothing. A search of the added diff lines for inline shell substitutions (!...) and hook, allowed-tools, mcpServers, or lspServers keys also matched nothing. The check does not apply to this diff, so it passes.
Full details: Public-Safe Content
Explanation
Checked the reviewed diff (refs/coderabbit/pre-merge-check/base..head), the PR title and the PR description against the Public-safe content criteria. - Credentials, tokens, private keys: none found in added lines. The only key-like values are synthetic sha256: digests built from repeated hex characters (for example "a".repeat(64), "b".repeat(64)) in crates/l30_storage/sbx/mgr/store/src/db/runtime_upgrades/tests.rs and crates/l30_storage/sbx/mgr/store/src/db/tests/execution_binding.rs. These are obviously fake test values, which the check allows. - Internal hostnames, URLs, or private tracker, chat, or document links: none in the diff or the description. Cargo.lock gained no new source = or URL lines. - Cloud account IDs or real ARNs: none found. - Cluster or environment names: none found. Kernel and runtime version strings in the tests (for example 6.1.155, 1.15.1) are fixture values, not production measurements. - Absolute personal-workstation paths: none. The only path strings are repository-relative crate paths. - Production logs, query output, or measurements: none. The PR description gives test pass and fail counts (12,424 passed, 41 failed). These are CI test results, not production data. - Incident details or unfixed security vulnerabilities: none. The description discusses socket options such as IP_TRANSPARENT as a code move, not as a vulnerability. The three orig_dst files are pure renames (R100) with unchanged content, so they add no new sensitive text.

@coderabbitai About keeping a kernel component in the selected-create fixture: fixed in 650bfba.
The replaced catalog metadata: on main, each catalog fixture carried exactly one component, a boot kernel in vmlinux format.
The new fixtures: both synthetic fixtures now carry a synthetic kernel component of that shape. In runtime_upgrades/tests.rs, the upgrade source and target also differ again in runtime and state-format versions, as the catalog pair did.
Mutation check: I temporarily made upsert_sandbox_execution_metadata_in_transaction drop ArtifactComponentKind::Kernel before serialising. With the new fixtures, 6 store tests fail, including selected_create_and_cleanup_intent_commit_or_roll_back_together and the runtime-upgrade bind and rollback tests. With the previous fixtures, only the existing round-trip test failed. The mutation was reverted.
For best results, initiate chat on the files or code changes.

@ac-pplx I verified that the selected-create fixture in 650bfbac includes the kernel and that the test compares the stored metadata with the fixture. This addresses my concern.

# Test economy: focused tests at the right layer
## Configuration changes: prove a contract, not the values
**Reviewer stop rule:** before retaining or modifying an existing configuration
test, require the reachable regression, independent oracle, coverage gap, and
owning layer. If the only failure is "the configured value or file layout
changed", reject the test; renaming it or wrapping it in a renderer does not fix
the gap.
@coderabbitai Here is the reasoning for the two points behind the risk rating, for the human reviewer.
Removed assertion (runtime_upgrades/tests.rs): assert_eq!(target.environment(), Some(target_definition.reference())) checked that the compiled catalog's target metadata was bound to its own definition's reference. It tested the fixture, not the store. The synthetic fixture builds the target with with_environment(target_reference), so the same assertion would be a tautology. Store coverage is now stronger than before: when the store is made to drop the kernel component, 6 tests fail, against 1 with the old fixtures (details in my previous comment).
Timeout validation (spaced/guest/protocol/src/validate.rs): the check only rejects a timeout that can't be added to "now" (checked_add overflow). It doesn't compute any deadline; callers still arm their own tokio timers.
tokio::time::Instant wraps std::time::Instant. Outside a paused test runtime, now() reads the same instant on both.
Inside a paused runtime, the two differ by the time the test has advanced, which is seconds to hours. That is negligible next to the overflow boundary.
timeout_rejects_values_that_overflow_the_runtime_clock (i64::MAX seconds) still rejects.
The validators are called from the guest execution and server crates. Their paused-clock tests pass short timeouts, nowhere near the boundary.
For best results, initiate chat on the files or code changes.

@ac-pplx The fixture explanation matches the code: the synthetic target and its reference are created together, so repeating the removed assertion would check fixture construction.
The timeout check does not create a deadline. The existing test asserts rejection of i64::MAX seconds. Different clock readings can still change the result for a duration near the overflow boundary; that test does not establish equivalence at the boundary.
The validators also have host-server call sites, in addition to the guest call sites. I did not rerun the mutation check or paused-clock tests.

# Test economy: focused tests at the right layer
## Three coverage questions
1. **What regression does this uniquely catch?** Name a concrete, reachable
regression and the independent contract or oracle that determines correctness
(not copied implementation or configured literals). Identify the coverage gap.
If an existing test already fails when that regression happens, do not write
a new one —
point at the existing test in the PR body if reviewers might wonder.
A change with no coverage gap legitimately adds **zero** tests.

# Test economy: focused tests at the right layer
## One contract clause, one test
Test the *contract* — the promise callers rely on — not the implementation's
shape. Symptoms of implementation-shaped testing:
- One test per internal branch or private helper, rather than per observable
promise. If a refactor that preserves behavior would break the test, the
test is pinning implementation.
- Asserting intermediate state that no caller can observe.
- A new test per PR iteration: when review changes the fix, rewrite the
test's *inputs*, don't accrete a second test alongside the first.
…entries
- sbx-mgr-store's tests built execution metadata from node-runtime-core's
compiled catalog, an l40_api crate. The store checks a binding's runtime
kind against the sandbox row and its environment reference against an
upgrade's target, and otherwise compares whole values, so synthetic
Firecracker metadata bound to synthetic `sha256:` references exercises the
same checks. The synthetic metadata keeps the shape the catalog's had: one
kernel component (role, version, format and a made-up `sha256:` digest),
and for the upgrade target a newer runtime, state format and kernel, so the
tests' whole-value comparisons still fail if the store drops a component.
The dev-dependency goes.
- net-common's `host-sockets` feature carried `orig_dst`, generic Linux
transparent-proxy socket options (IP_TRANSPARENT, IP_RECVORIGDSTADDR,
SO_ORIGINAL_DST, SO_MARK, IP_FREEBIND), and with it tokio. It moves
unchanged into a new Foundation crate, pplx-space-transparent-proxy-socket;
net-gateway-client keeps its `orig_dst` path as an alias of that crate.
- spaced-guest-protocol used tokio only for `tokio::time::Instant::now()` in
the timeout overflow check; std's Instant is the same clock outside a
paused test runtime.
The three baseline entries are removed. spaced-common's entries stay: closing
them means splitting the crate into a protocol crate and a transport crate.

Summary
This closes three
layersbaseline entries that don't belong to common-core.dev_directionnow runs with an empty baseline.dev_direction, sbx-mgr-store → node-runtime-core: two store tests built execution metadata from node-runtime-core's compiled catalog, an API-layer crate. The store checks a binding's runtime kind against the sandbox row and its environment reference against an upgrade's target, and otherwise compares whole values. So synthetic Firecracker metadata bound to syntheticsha256:references exercises the same checks, and the dev-dependency is gone.domain_dependencies, net-common → tokio: tokio came only through the optionalhost-socketsfeature. That feature'sorig_dstmodule is generic Linux socket-option code for transparent proxying (IP_TRANSPARENT,IP_RECVORIGDSTADDR,SO_ORIGINAL_DST,SO_MARK,IP_FREEBIND). It moves unchanged into a new Foundation crate,pplx-space-transparent-proxy-socket. net-gateway-client already re-exportedorig_dst, and now re-exports it from the new crate, sopplx_space_net_gateway_client::orig_dstkeeps working.domain_dependencies, spaced-guest-protocol → tokio: the timeout overflow check now usesstd::time::Instant::now()instead oftokio::time::Instant::now(). Outside a paused test runtime they read the same clock, and the error text is unchanged.spaced-common's
model_protocolanddomain_dependenciesentries stay. The crate holds both the compiled spaced protos and the UDS/vsock/retry transport, so closing them means splitting it into a protocol crate and a transport crate, which is a larger change.Downstream:
