From 99a8e1667f3e19fc119a15b259c132465eed2d51 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 13 Feb 2026 02:12:31 +0000 Subject: [PATCH 01/14] Fix CI test failure: add GCP WIF auth and guard cost-gating The preflight lint-upsert step runs `cargo test --workspace --lib` which triggered a panic in the credential_lifecycle live flow test. In CI (GITHUB_ACTIONS=true), the guard functions panicked on missing GCP secrets even when the test should have been skipped by cost gating. Three-part fix: 1. Guard functions (core/test/src/fermi.rs): When GUNBC_TEST_MAX_COST is explicitly set, skip tests that exceed the budget or lack secrets instead of panicking. This allows the preflight test gate (cost=S) to run without cloud credentials while preserving the CI safety net for misconfigured workflows. 2. Preflight (lib/transport/src/preflight.rs): Pass GUNBC_TEST_MAX_COST=S to the test gate step so live/integration tests are skipped during preflight. Added run_cargo_command_with_env for env var injection. 3. CI workflow (codegen_cli.rs, ci/graph.rs, render.rs): Add permissions block (id-token: write) and GCP secret env vars to the generated GitHub Actions YAML so live flow tests can authenticate via Workload Identity Federation in the full CI pipeline. Also adds structural test (mock_spec_registration.rs) to catch testgen targets with live_required secrets that have cost <= S, and 9 unit tests for the guard function behavior. https://claude.ai/code/session_014cTfu4arnDzFZCELaR26P4 --- core/ir/src/transport/ci/render.rs | 31 +++ core/test/src/fermi.rs | 223 +++++++++++++++++++++- gunbc-dag/src/bin/codegen_cli.rs | 39 +++- gunbc-dag/src/ci/graph.rs | 33 ++++ gunbc-dag/tests/mock_spec_registration.rs | 106 ++++++++++ lib/transport/src/preflight.rs | 32 +++- 6 files changed, 453 insertions(+), 11 deletions(-) diff --git a/core/ir/src/transport/ci/render.rs b/core/ir/src/transport/ci/render.rs index fb689494d62..9f1182eed51 100644 --- a/core/ir/src/transport/ci/render.rs +++ b/core/ir/src/transport/ci/render.rs @@ -107,6 +107,19 @@ pub struct RenderConfig { /// Job-level timeout in minutes.

Fix probe→observer recursion (#1): Intermediate observers are now promoted to probes unconditionally (not gated on Exact matchers). Tests are seeded from baseline DryRun, so concrete values aren't needed. This enables compositional segment testing A→B + B→C. 2. Fix extract_observers() seen/merge bug (#2): NodeExamples with only input-dependent matchers (Exact/Contains) no longer suppress valid chain-safe matchers from live_expected_outputs for the same node. Switched to merge-by-node approach using BTreeMap union. 3. Make gaps fail CI (#3): Coverage gaps now generate a failing test_observability_invariant_no_gaps test instead of just a header comment. Aligns behavior with the stated invariant. 4. Make lowering failures loud (#4): DAG lowering errors now generate a failing test_probe_observer_lowering_failed test instead of silently returning None and skipping all chain tests. 5. Seed policy fail-closed (#5/#8): Inverted seed_policy_for_type to whitelist known-safe primitive types (String, Bool, Int, etc.) and default unknown types to ExplicitSeedRequired. New types and aliases no longer silently fall into placeholder generation. 6. Additional hardening: - Add input_mocks as a probe source (#6) for DAGs seeded via entry input ports - Track weak observers (Any/IsRequest/IsResponse) in coverage reports (#5) so teams can identify low-value assertions - Promoted probes now appear in analysis results - ParamType::from(&str) panics on unknown types instead of silently defaulting to Str (#9) - Int parsing returns ParseError::InvalidInt instead of unwrap_or(0) https://claude.ai/code/session_014cTfu4arnDzFZCELaR26P4 --- core/cli/src/lib.rs | 28 ++- core/codegen/src/testgen/codegen.rs | 107 ++++++++- core/codegen/src/testgen/probe_observer.rs | 248 +++++++++++++++------ 3 files changed, 300 insertions(+), 83 deletions(-) diff --git a/core/cli/src/lib.rs b/core/cli/src/lib.rs index 8bb7b88f98a..309a6e170e0 100644 --- a/core/cli/src/lib.rs +++ b/core/cli/src/lib.rs @@ -32,9 +32,14 @@ impl ParamType { impl From<&str> for ParamType { fn from(s: &str) -> Self { match s { + "String" | "Str" => Self::Str, "Bool" => Self::Bool, "Int" => Self::Int, - _ => Self::Str, + other => panic!( + "ParamType::from(\"{}\") — unknown type; \ + use ParamType::Str, ParamType::Int, or ParamType::Bool", + other + ), } } } @@ -228,7 +233,12 @@ pub fn parse(argv: &[String], schema: &[CliParam]) -> Result { let value = match param.type_id { ParamType::Bool => Value::Bool(val == "true"), - ParamType::Int => Value::Int(val.parse::().unwrap_or(0)), + ParamType::Int => Value::Int( + val.parse::().map_err(|_| ParseError::InvalidInt { + flag: param.flag_name(), + value: val.clone(), + })?, + ), ParamType::Str => Value::Str(val.clone()), }; values.insert(param.port_name.clone(), value); @@ -407,11 +417,17 @@ mod tests { } #[test] - fn test_invalid_int_defaults_to_zero() { - // Matches generated CLI behavior: .parse().unwrap_or(0) + fn test_invalid_int_returns_error() { let schema = vec![CliParam::new("count", "Int")]; - let result = parse(&argv(&["prog", "--count", "not-a-number"]), &schema).unwrap(); - assert_eq!(result.values["count"], Value::Int(0)); + let result = parse(&argv(&["prog", "--count", "not-a-number"]), &schema); + assert!(result.is_err()); + assert_eq!( + result.unwrap_err(), + ParseError::InvalidInt { + flag: "count".to_string(), + value: "not-a-number".to_string() + } + ); } #[test] diff --git a/core/codegen/src/testgen/codegen.rs b/core/codegen/src/testgen/codegen.rs index 971db53880c..bbac1a8ce1c 100644 --- a/core/codegen/src/testgen/codegen.rs +++ b/core/codegen/src/testgen/codegen.rs @@ -48,17 +48,30 @@ enum SeedContext { RealSingleNodeRequiredInput, } +/// Determine seed policy for a type. +/// +/// This is **fail-closed**: only types on the known-safe whitelist use +/// generated placeholders.

Guard functions now treat empty-string env vars as missing secrets. GitHub Actions exports undefined secrets as "" (${{ secrets.X }} resolves to empty string when X is not configured). Previously env::var(k).is_err() returned false for "", so guards thought secrets were present. New env_is_present() helper rejects both unset and empty values. 2. Skip seed assertion for nodes with skip_node_example. The fail-closed seed policy (from PR feedback) correctly requires explicit seeds for semantic types like CloudSecretConfig, but was panicking on nodes already marked skip_node_example (e.g. bind_secret). These are known resource/boundary nodes that won't be tested in single-node Real mode, so the seed assertion is unnecessary. https://claude.ai/code/session_014cTfu4arnDzFZCELaR26P4 --- core/codegen/src/testgen/codegen.rs | 50 ++++++++++++- core/test/src/fermi.rs | 109 +++++++++++++++++++++++++++- 2 files changed, 155 insertions(+), 4 deletions(-) diff --git a/core/codegen/src/testgen/codegen.rs b/core/codegen/src/testgen/codegen.rs index bbac1a8ce1c..0fde83d0dea 100644 --- a/core/codegen/src/testgen/codegen.rs +++ b/core/codegen/src/testgen/codegen.rs @@ -2122,6 +2122,18 @@ impl<'a, T: Clone> TestGenerator<'a, T> { node: &gunbc_ir::Node, base_inputs: &BTreeMap, ) { + // Nodes explicitly marked skip_node_example are resource/boundary nodes + // that won't be tested in single-node Real mode — no seed assertion needed. + if let Some(spec) = &self.mock_spec { + if spec + .skipped_node_examples + .iter() + .any(|s| s == &node.id.0) + { + return; + } + } + let mut missing = Vec::new(); for port in &node.inputs { @@ -6183,6 +6195,8 @@ mod tests { #[test] #[should_panic(expected = "Optional input tests require explicit seeds for required semantic inputs in Real single-node mode")] fn test_optional_inputs_require_explicit_semantic_seed() { + use gunbc_test::{NodeExample, OutputMatcher}; + let mut dag: Dag<()> = Dag::new(); dag.add_node(Node::opaque( "parse", @@ -6194,9 +6208,16 @@ mod tests { (), )); + // Provide a node_example with outputs (satisfies the I/O example + // requirement) but do NOT seed the TransportResponse input — the + // seed assertion should fire. let spec = MockSpec::new("opt") .boundary("parse", "result", Value::Str("ok".into())) - .skip_node_example("parse"); + .node_example( + NodeExample::new("parse") + .input("fallback", Value::Str("fb".into())) + .output("result", OutputMatcher::non_empty()), + ); let generator = TestGenerator::new(&dag) .with_mock_spec(spec) @@ -6204,6 +6225,33 @@ mod tests { let _ = generator.generate_test_module("opt", "build_opt_graph()"); } + #[test] + fn test_skip_node_example_bypasses_seed_assertion() { + // Nodes with skip_node_example should NOT panic about missing seeds + // — they are known resource/boundary nodes that won't be tested + // in single-node Real mode. + let mut dag: Dag<()> = Dag::new(); + dag.add_node(Node::opaque( + "resolver", + vec![ + port("config", "TransportResponse"), + optional("name", "OptionalString"), + ], + vec![port("result", "String")], + (), + )); + + let spec = MockSpec::new("skip") + .boundary("resolver", "result", Value::Str("ok".into())) + .skip_node_example("resolver"); + + let generator = TestGenerator::new(&dag) + .with_mock_spec(spec) + .with_mock_spec_fn("crate::mock_spec()"); + // Should NOT panic — skip_node_example suppresses the seed check. + let _ = generator.generate_test_module("skip", "build_skip_graph()"); + } + #[test] fn test_generate_with_satisfies_matcher_uses_runtime_check() { use gunbc_test::{NodeExample, OutputMatcher}; diff --git a/core/test/src/fermi.rs b/core/test/src/fermi.rs index 8d72e70ef8f..29a04c4e924 100644 --- a/core/test/src/fermi.rs +++ b/core/test/src/fermi.rs @@ -115,6 +115,16 @@ fn cost_limit_is_explicit() -> bool { .is_some() } +/// True when an env var is set to a non-empty value. +/// +/// GitHub Actions exports undefined secrets as empty strings (`${{ secrets.X }}` +/// resolves to `""` when `X` is not configured).
