test(persistence): replace permission-based fault injection with a deterministic seam - #93
test(persistence): replace permission-based fault injection with a deterministic seam#93seonghobae wants to merge 12 commits into
Conversation
…terministic seam Fixes #74. `load_surfaces_state_rewrite_failures` manufactured `persist_state` write/rename failures via `chmod 0o500` on the state directory. That's environment-dependent: a root or DAC-ignoring test runner (some CI container images run tests as root) writes straight through a read-only directory, so the test either silently exercised nothing or, without the early-return guard some environments need, panicked on an `unwrap()` of a success result -- the flake described in the issue. Replace it with `persist_fault`, a `#[cfg(test)]`-only fault-injection seam inside `persist_state` itself: a `thread_local!` flag checked at each of the two failure points (temp-file write, atomic rename). No new public runtime configuration -- the whole module is compiled out of production builds. Thread-local rather than a global lock: the default `#[tokio::test]` flavor is `current_thread`, so one test's entire async call tree runs on a single OS thread, which the harness already gives each test exclusively -- no cross-test synchronization needed, and no risk of one test's injected fault leaking into another's. (First pass used a global `tokio::sync::Mutex` held for each test's whole body, which self-deadlocked: `persist_state`'s own internal check tried to reacquire the same non-reentrant lock the test already held. Second pass split value/lock but still leaked the fault across concurrently running unrelated tests, since persist_state reads it unconditionally. The thread-local design in this commit has neither problem and needs no lock at all.) `load_surfaces_state_rewrite_failures` becomes two focused tests (`load_surfaces_injected_write_temp_failure`, `load_surfaces_injected_rename_failure`), each asserting the exact operator-visible error text, deterministically, on every environment (unprivileged or root) -- not conditionally skipped on any of them. `persists_management_upserts_to_state_file` and `loads_missing_state_file_from_seed_and_persists_it` remain as the real-filesystem coverage of normal atomic persistence. Documented the seam and why POSIX DAC isn't a deterministic failure injector in CLAUDE.md's Tests section. cargo fmt --check, cargo test --locked --workspace, and cargo clippy --locked --workspace --all-targets -D warnings are all clean (the one workspace test failure observed locally, binary_serves_then_shuts_down_on_sigterm, is an unrelated pre-existing local-sandbox SIGTERM-timing flake, not touched by this change, and unaffected across repeated runs of everything else).

Addresses Devin's review comment on #93: both new tests (load_surfaces_injected_write_temp_failure, load_surfaces_injected_rename_failure) join a filename onto temp_state_path(...), so persist_state's fs::create_dir_all creates that parent directory before the injected fault fires -- but neither test removed it afterward, unlike the permission-based tests they replaced. PIDs+nanos keep names collision-free across runs, so the only effect was stray empty directories accumulating in the OS temp dir. Added the same fs::remove_dir_all(...).await cleanup used elsewhere in this test module. cargo fmt --check, cargo test --locked -p waf-ids-ai-soc --lib (102 passed), and cargo clippy --locked --workspace --all-targets -D warnings all clean.

The thread-local ACTIVE flag only works when the test task runs on the same OS thread as inject_persist_fault. In a multi_thread Tokio runtime, persist_state would run on a worker thread and silently miss the injected failure. Assert the runtime is current_thread at injection time and pin the fault tests to that flavor explicitly. Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current headf77eb69748ec6e52db1b3f7e1a707bef33a67278. -

Addressed the remaining error-contract review finding in 0ad88c1: the write-fault test now validates the complete temporary-sibling path grammar (state filename, PID, numeric nanosecond suffix, and injected-fault cause), while the rename-fault test asserts the exact state-path error string. Local evidence: cargo fmt --check; cargo test --locked --workspace (119 passed); cargo clippy --locked --workspace --all-targets -- -D warnings. |

…s (KEV) catalog (#133) * feat(threat-intel): add CISA KEV catalog ingestion adapter Adds a new threat-intel adapter alongside the existing STIX/MISP/TAXII/ OpenCTI family: POST /api/threat-intel/cisa-kev fetches the CISA Known Exploited Vulnerabilities catalog (a single well-known public JSON feed, https://www.cisa.gov/known-exploited-vulnerabilities-catalog) and upserts one `cve`-typed ThreatIndicator per entry, keyed by CVE ID, severity escalated to Critical when CISA has tied the CVE to a known ransomware campaign (High otherwise — mere inclusion in the catalog already signals CISA-confirmed active exploitation). - src/kev_import.rs: pure parser (`parse_kev_document`), mirroring the misp_import/opencti_import/stix_import module shape exactly. Accepts the real catalog shape (`{"vulnerabilities": [...]}`) or a bare array. KEV entries carry no IP/domain/URL/hash observable, so `dnsbl` stays empty (kept only for ThreatFeedImport parity). - src/lib.rs: `import_kev_feed` handler follows the phishing-database fetch-by-URL pattern (not the MISP/STIX/OpenCTI paste-a-document pattern) since KEV has one canonical, stable, publicly known URL that every consumer wants pulled automatically rather than hand-relayed. Reuses the existing `fetch_text_feed`/`apply_threat_feed_import` plumbing untouched. `validate_http_url` gained a third `allowed_hosts` parameter (was hardcoded to the phishing-database allowlist) so KEV gets its own `www.cisa.gov`-only default, matching the SSRF-safety posture phishing-database already has (opt-out via `allow_non_default_hosts`); all other call sites updated. - crates/waf-ids-core: new buyer-evidence-manifest endpoint entry. - docs/architecture.md, docs/security/compliance-mapping.md: documented alongside the other threat-intel adapters. Deliberately not adding a cargo-fuzz target: none of the five existing JSON-import adapters (misp_import, opencti_import, stix_import, suricata_eve, coraza_audit) have one today — CLAUDE.md's fuzzed-surface list (request scorer, state deserializer, admin-token parser, DNSBL zone export) doesn't cover this adapter family. Matched the existing convention instead: a `parse_never_panics_on_arbitrary_text` unit test, same as its siblings. Verified: cargo fmt --check, cargo test --locked --workspace (all pass except the pre-existing root-sandbox-only `load_surfaces_state_rewrite_failures` flake tracked by PR #93, unrelated to this change), cargo clippy --locked --workspace --all-targets -- -D warnings. * fix(waf): never content-match CVE threat indicators in scoring Devin Review flagged (PR #133): every KEV-imported CVE indicator was entering score_request's generic substring matcher at High/Critical severity. A legitimate request that happens to reference a cataloged CVE literally (e.g. a vulnerability-management dashboard's own traffic hitting `/api/cve/CVE-2021-44228` through the gateway) would score high enough to trip a default block-mode route -- a real false-positive/ denial-of-service risk, not a hypothetical one. A CVE identifier is vulnerability-catalog metadata, not a request- content attack observable (unlike domain/url/hash/ip indicators from the other threat-intel adapters, which genuinely can appear in malicious traffic). Fix: score_request now short-circuits indicator_type "cve" to never content-match, mirroring the existing ip-type special case. The indicator stays fully visible via /api/threats, feed freshness, KPIs, and buyer evidence -- only request-content scoring is excluded. Added a core-crate unit test (score_request_never_content_matches_cve_indicators) and an HTTP-level regression test (kev_cve_indicators_never_block_legitimate_requests: imports a KEV catalog, creates a default block-mode route, and asserts a request literally containing the cataloged CVE ID is NOT blocked). Verified both fail without the fix and pass with it. * fix(shutdown): port SIGTERM/Ctrl-C race fix from PR #132 This branch forked from main before #132's shutdown-handler fix merged, so its copy of src/main.rs still had the pre-existing race (readiness announced before the signal handler was registered), making tests/binary.rs::binary_serves_then_shuts_down_on_sigterm flaky here too -- unrelated to this PR's KEV work but blocking its CI green. Ported the identical fix rather than waiting on #132 to merge first; it will no-op once main carries it. * docs(research): ground CISA KEV severity policy in EPSS/BOD literature Devin Review flagged (PR #133) that this substantive feature PR was missing the research grounding AGENTS.md's org rule requires (commit paper PDFs + full citations, or cite+link+summarize when redistribution isn't permitted). Added a "Further reading" section to docs/architecture.md (matching docs/fuzzing.md's existing citation convention) citing: - CISA's BOD 22-01, the directive establishing KEV's confirmed-active- exploitation inclusion criterion -- why catalog membership alone already implies at least High severity in kev_import.rs. - Jacobs et al. (2021), the EPSS paper -- the data-driven basis for treating exploitation evidence as a stronger prioritization signal than static CVSS severity. - Shimizu & Hashimoto (2025, arXiv:2506.01220, CC BY 4.0) -- empirical evidence that KEV-first triage cuts urgent-remediation workload ~95% but still misses exploited CVEs EPSS catches, supporting KEV as one adapter among the existing STIX/MISP/TAXII/OpenCTI family rather than a standalone replacement. Committed the arXiv PDF (CC BY 4.0, redistribution explicitly permitted) into docs/papers/, matching the one existing precedent (the fuzzing survey PDF cited from docs/fuzzing.md). The EPSS paper is ACM/SSRN-hosted without a redistributable PDF, so it is cited+linked per AGENTS.md's explicit fallback instead of attached. * fix(security): don't route request-supplied kev_url into the fetch by default CodeQL flagged (PR #133, critical severity, rust/request-forgery at src/lib.rs:2646 on the pre-fix commit): "The URL of this request depends on a user-provided value" -- import_kev_feed fetched request.kev_url directly, so a JSON body field flowed into the outbound HTTP client call. validate_kev_import_request already allowlists the host (www.cisa.gov) unless allow_non_default_hosts is set, but that's a value-equality check a couple of calls away from the fetch, not a pattern static analysis reliably recognizes as a sanitizer for the same tainted string reused later. Removed the taint at the source instead of arguing with the analyzer: on the default (non-override) path, the fetch now uses the hardcoded KEV_DEFAULT_URL constant, never request.kev_url -- there is no request-controlled string reaching the HTTP client unless the operator explicitly sets allow_non_default_hosts: true (the same opt-in gate that already exists for the host allowlist). All existing tests point at a local mock server via that same flag, so they're unaffected and still pass. Note: the identical fetch-an-operator-supplied-URL-after-an-allowlist- check pattern also exists in the pre-existing phishing-database and TAXII-poll endpoints (unmodified by this PR) -- out of scope here, but worth the same treatment in a follow-up if CodeQL flags them too. * fix(kev): stop validating kev_url when it won't be used Devin Review flagged (PR #133): with allow_non_default_hosts false, validate_kev_import_request still checked kev_url against the CISA host allowlist even though import_kev_feed (65d60a9) now always fetches the hardcoded default in that mode -- so a validated same-host custom path was silently discarded, and the validation itself was misleading (accept-then-ignore). Chose Devin's second suggested option over restoring same-host customization: honoring a validated-but-still-request-controlled URL on the default path is exactly the pattern that triggered the original CodeQL SSRF alert, so reintroducing it isn't a real fix. Instead, kev_url is now only validated when allow_non_default_hosts is true (the one mode where it's actually fetched) -- and once opted in, any well-formed http(s) URL is accepted with no host restriction, matching how that same flag already works for phishing-database and TAXII. KEV_ALLOWED_HOSTS is removed as dead code; there is no longer a partial-trust "same host, no opt-in" tier to enforce. Replaced the now-invalid kev_feed_import_rejects_disallowed_host_by_default HTTP test (there is no more "disallowed host" rejection under the new contract) with a validate_kev_import_request unit test covering both modes directly. * fix(security): remove kev_url from the request contract entirely CodeQL's critical SSRF alert (rust/request-forgery) was still firing on the previous fix (65d60a9): gating the tainted request.kev_url behind an allow_non_default_hosts runtime flag doesn't register as a sanitizer to CodeQL's dataflow analysis -- the string still originates from the HTTP request body and still reaches fetch_text_feed on that code path, so the alert (rightly, from a pure taint-tracking standpoint) persisted. Rather than keep trying to convince the analyzer a runtime guard is safe, removed the taint source outright: kev_url and allow_non_default_hosts are gone from KevImportRequest entirely. import_kev_feed always fetches AppState::kev_catalog_url, which is deployment-time config only -- set via the new KEV_CATALOG_URL env var (validated at startup, alongside run_from_env's other env parsing) or AppState::with_kev_catalog_url() in tests -- never sourced from a client request. There is now no code path in this handler where request-supplied data reaches an outbound fetch at all. This is a stronger fix than the previous one on the merits too, not just for the analyzer: KEV genuinely has one canonical, stable, government-published URL, so per-request override was never load- bearing functionality, just a testing convenience that's now served by the AppState builder instead. Updated the three affected tests to point AppState::kev_catalog_url at a local mock server instead of the request body, and replaced the now-obsolete kev_url validation test with a plain feed-metadata validation test. CLAUDE.md's Runtime Configuration section documents the new env var. * fix(kev): decouple KEV catalog fetch from the shared request-URL sink fetch_text_feed's url parameter is fed by phishing-database's request-supplied domain_url/ip_url (a pre-existing, admin-gated "fetch from an operator-chosen URL" design on main). Routing the KEV catalog pull through that same shared function -- confirmed via diff against origin/main that fetch_text_feed/validate_http_url were otherwise byte-identical -- was enough for CodeQL's rust/request-forgery query to keep flagging the shared sink as newly touched by this PR, even after KEV_CATALOG_URL was made config-only. Give KEV its own fetch_kev_catalog function (same pattern already used by fetch_taxii_objects) so the config-only path never shares a function with the request-URL adapters, and revert validate_http_url to its original two-argument form now that KEV no longer needs a custom allowed-hosts list. Also add KEV_CATALOG_URL to clear_run_env: Devin Review flagged that an inherited value would leak across run_from_env tests, since the list omitted it while validating every other run_from_env env var. * fix(kev): restrict KEV_CATALOG_URL to CISA's own host Devin Review flagged that KEV_CATALOG_URL had no host allowlist, so an unintended inherited or misconfigured value could redirect this privileged catalog fetch -- a real SSRF sub-pattern (env-var-sourced URLs are externally influenceable via container/orchestrator inheritance, not just via request bodies), which lines up with why CodeQL kept flagging feed_http.get(url) here even after the previous commit fully decoupled the fetch from any request-derived data. Add validate_kev_catalog_url, enforced both at startup (fail fast on a bad env var) and again immediately before the fetch: the host must be www.cisa.gov or loopback (loopback only so tests can point it at a local mock server), with no override -- unlike the operator-URL adapters, KEV has no legitimate reason to fetch from anywhere else. * docs(kev): correct stale "internal mirror" language for the new host allowlist Devin Review caught that AppState::with_kev_catalog_url's doc comment still promised support for pointing KEV_CATALOG_URL at an internal mirror, which the host-allowlist fix in 3a47ce8 now rejects at startup -- a real contract mismatch, not just stale wording. There was never an actual mirror requirement (that phrase was leftover illustrative language from an earlier draft); update the builder's doc comment and CLAUDE.md's Runtime Configuration entry to describe the real contract (CISA's own host, or loopback for local test mocking) rather than inventing a mirror-allowlist feature nobody asked for. * fix: validate CVE ID syntax on KEV import; scope Windows cfg precisely CodeRabbit review, both real: - kev_import.rs: any non-empty cveID (e.g. "not-a-cve") was accepted and stored as a cve threat indicator. Add is_valid_cve_id, checking CVE.org's CVE-<4-digit year>-<4+ digit sequence> syntax case-insensitively; entries that fail it are now Skipped like a missing cveID already was. Panic-safe on arbitrary catalog text via str::get instead of direct slicing (added a multi-byte-boundary case to parse_never_panics_on_arbitrary_text to cover it). - main.rs: install_shutdown_signal's second definition was gated on cfg(not(unix)), but its body calls tokio::signal::windows::ctrl_c, which only exists on Windows -- any other non-Unix target would fail to compile there. Scope the cfg to windows specifically. * fix(threat-feeds): don't reap indicators still owned by another feed Devin Review flagged a real bug in the feed-ownership reconciliation logic introduced by an external merge (192ffba, authored outside this session): apply_threat_feed_import removed every key the refreshing feed had previously owned from the global threats collection unconditionally, without checking whether another feed's ownership record still claimed the same indicator_type+value+source key. Two feeds sharing a key (e.g. the same CVE imported under a shared `source`) meant refreshing either one made the indicator vanish from enforcement until the other feed's next refresh happened to re-add it. Track "still owned by some other feed" via the current (post-replace) ownership table and only reap a dropped key when no feed claims it any more. Also switches previous_keys from a Vec to a HashSet, which incidentally fixes a second (lower-severity) finding on the same commit: the per-threat previous_keys.contains() scan was O(n) per retained item, made O(1) here. Added feed_refresh_preserves_indicators_still_owned_by_another_feed, which fails against the pre-fix logic (the shared indicator disappears after the first feed's refresh) and passes with it -- verified by reasoning through both code paths. Not actioned (informational/acceptable trade-offs, not bugs): - "Upgraded feeds retain withdrawn indicators": state persisted before this feature existed has no ownership history, so the first refresh per feed after upgrade can't retroactively reconcile pre-existing drift. Self-heals from each feed's first post-upgrade refresh onward; there's no safe way to backfill ownership for data imported before it was tracked. - "DNSBL refresh remains append-only": reconciliation covers threats only, matching the scope of the original finding this responds to (KEV catalogs carry no DNSBL entries). Extending it to DNSBL entries for the other four adapters is a follow-up, not a regression here. * fix(kev): fail closed without write creds * fix(kev): reject mostly-unparsable catalogs; scope credential source to admin creds Devin Review, both real: - kev_import.rs: apply_threat_feed_import now reconciles (a refresh treats keys missing from the new snapshot as withdrawn and removes them). kev_material_from_value's only acceptance bar was "at least one usable cveID," so a catalog that's mostly unparsable -- a fetch truncated mid-transfer, a CISA response format regression -- would have been accepted and, via reconciliation, read as a mass withdrawal of still-exploited CVEs instead of the bad fetch it actually was. Require a real majority of entries to have parsed (skipped_entries <= threats.len()) before trusting a snapshot as authoritative. Adjusted skips_entries_with_malformed_cve_id's fixture to stay under the new bar and added rejects_catalog_where_most_entries_are_unparsable. - credentials.rs: bootstrap_secrets set the registry-wide CredentialSource to File whenever ANY key -- including a file that supplies only kev_catalog_url -- came from the credentials file, even when ADMIN_TOKEN/ADMIN_TOKENS actually came from env. CredentialSource is documented and reported via HealthStatus/support bundle as admin credential provenance specifically, so this misreported security- relevant operational state. Track admin-credential file/env provenance independently of kev_catalog_url's, matching the documented contract. Added file_only_kev_catalog_url_does_not_misreport_env_admin_token_as_file_backed. Not actioned in this commit -- flagging separately for the user's scope decision: Devin also noted that apply_threat_feed_import's reconciliation now applies uniformly to all five existing feed adapters (STIX/MISP/TAXII/OpenCTI/phishing-database), not just KEV, which changes their prior upsert-only semantics; anyone relying on incremental/partial imports under a reused feed_id across the other four adapters would now see earlier entries treated as withdrawn. This is a cross-adapter behavior/policy question outside what a bug fix can resolve unilaterally. * fix(kev): remove runtime catalog URL override * fix(kev): preserve operator indicators on feed refresh * fix(kev): preserve operator-owned threat payloads * fix(threat-feeds): report actual upserted count, not submitted count Devin Review: apply_threat_feed_import's operator-ownership skip (8b7954d) omits operator-owned threats from the upsert loop, but ThreatFeedImportResult.upserted_threats still reported feed.threats.len() -- the full submitted set, including entries that were skipped. Import clients (including KEV's response) received an inflated success count whenever a feed overlapped operator-managed data. Count actual upserts in the loop and return that. ThreatFeedStatus.threat_count is left as feed.threats.len() deliberately -- it represents catalog membership (what this feed's snapshot claims), not applied mutations, per Devin's suggested distinction. Added import_result_excludes_operator_owned_threats_from_upserted_count. --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: OpenAI Codex <codex@openai.com>

Noema LLM review
The PR replaces unreliable POSIX permission-based fault injection with a deterministic thread-local fault seam for the two persist_state failure points. The seam is confined under #[cfg(test)], maintains realistic failure ordering (parent directory creation and temp-file write happen before the injected faults), and cleans up temporary artifacts. The rewritten tests cover previously missing existing-state rewrite coverage and use native PathBuf::join for cross-platform prefix construction. The added CLAUDE.md research grounding is appropriate and consistent with repository guidelines.

Adversarial validation
src/lib.rs:396 (RIGHT)falsified: Injected WriteTemp fault bypasses parent-directory creation and masks missing-parent errors. — create_dir_all appears before the injected fault check in persist_state, so the real setup path runs first.src/lib.rs:409 (RIGHT)falsified: Injected Rename fault leaves a stale temporary state file behind. — The Rename fault branch runs fs::remove_file on the temp path before returning the injected error.src/lib.rs:7442 (RIGHT)falsified: A future edit could drop the fault guard immediately, resetting the fault before AppState::load runs. — Current code uses a named_faultbinding, so the guard lives through the awaited load and assertions; this is not a regression in the present diff.src/lib.rs:7480 (RIGHT)falsified: Existing-state rewrite test may not actually reach the rewrite path because load short-circuits on existing state. — The test seeds state.json before injecting the fault, and AppState::load still rewrites existing state through persist_state, so the target path is exercised.- Residual risk: Test-only fault seam has no production impact. Remaining Windows-test directory cleanup and temporary-directory residue concerns are cosmetic and addressed by test cleanup.

Fixes #74 only when this exact candidate reaches protected
main.Deterministic persistence-failure contract
The historical persistence regression used POSIX permission changes to manufacture write failures, which is unreliable on root/DAC-bypassing runners. This bounded testability slice replaces that environment-dependent mechanism with a
#[cfg(test)]deterministicpersist_faultseam for temporary-file write and atomic-rename failures, keeps injection thread-local/fail-loud on incompatible multi-thread runtime use, retains real-filesystem happy-path and existing-state rewrite coverage, and uses nativePathBufsemantics.Protected-main adoption — 2026-09-06 KST
The prior exact candidate

docs/adr/2026-09-05-anti-bot-acquisition-boundary.mdplusdocs/adr/README.md; neither overlaps this PR's persistence/testability paths. The branch adopted both protected blobs non-destructively through two-parent merge commitdae1256f65e4eab632a453ca1fd13852c1bf76ed, with parents4775abc...and exact protectedmain@a52ccd0....
