For where Nyx is going, see the [Roadmap](ROADMAP.md). +## [Unreleased] + +## [0.8.0] - 2026-06-01 + +The dynamic-verification release. An attack-surface map, a sandboxed dynamic verifier, a framework adapter registry that grounds both, the per-language build infrastructure that makes per-finding verification affordable at corpus scale, and the first real-corpus acceptance gates. + +The attack-surface map and chain composer turn the flat finding list into a route-to-sink graph. The dynamic verifier re-runs every Medium-or-higher finding against a payload corpus and stamps a Confirmed / PartiallyConfirmed / NotConfirmed / Inconclusive / Unsupported verdict on each. The adapter registry (130+ entries across 8 languages) covers HTTP, message-broker, scheduled-job, GraphQL, WebSocket, middleware, and migration entry points. Per-language build pools and copy-on-write workdirs hold the with-verify wall-clock to within 1.5x of a static-only scan. + +### Attack-surface map + +- **`nyx surface` subcommand.** Prints the project's entry points, datastores, external services, and dangerous local sinks as text, JSON, Graphviz `dot`, or rendered SVG. Loads the persisted `SurfaceMap` from the most recent indexed scan when available, or rebuilds inline from source. `--build` forces a full pass-1 + call-graph walk so DataStore / ExternalService / DangerousLocal nodes populate on an unscanned project. +- **Surface page in `nyx serve`.** New `SurfacePage` renders the same graph in the browser UI, with ELK layout, sidebar navigation, and a wide-canvas SVG viewer. Persists alongside the index so the frontend reloads without a rescan. +- **Chain findings.** `ChainFinding` records connect a route entry point to a downstream sink via the call graph + surface map. The composer scores `(impact × evidence)` per chain, queues the top-N for composite reverification, and wires the result into `findings.json` / SARIF / the dashboard. Chains rank above isolated findings. + +### Framework adapter registry + +`src/dynamic/framework/` ships a `FrameworkAdapter` trait with concrete adapters across 8 languages (116 entries today, growing per release). Each adapter binds a route / handler / consumer pattern to a `FrameworkBinding` so the surface map and dynamic verifier can locate entry points without re-walking the AST. + +- **HTTP routers.** Flask, Django, FastAPI, Starlette (Python); Express, Koa, NestJS, Fastify (JS/TS); Spring, Quarkus, Micronaut, Jakarta Servlet (Java); Gin, Echo, Fiber, Chi (Go); Axum, Actix, Rocket, Warp (Rust); Rails, Sinatra, Hanami (Ruby); Laravel, Symfony, CodeIgniter (PHP). +- **New `EntryKind` variants.** `ClassMethod`, `MessageHandler`, `ScheduledJob`, `GraphQLResolver`, `WebSocket`, `Middleware`, `Migration` join the existing `RouteHandler` / `Function` set so the surface map shows non-HTTP entry surfaces. +- **Message broker handlers.** Kafka, AWS SQS, Google Pub/Sub, NATS, and RabbitMQ consumers across Python, Node, Java, and Go. +- **Scheduled jobs.** Celery (Python), Sidekiq (Ruby), Quartz (Java), plain cron expression recognition. +- **GraphQL resolvers.** Apollo, Relay, gqlgen, Juniper, Graphene. +- **WebSocket handlers.** ws, Socket.IO, ActionCable, Django Channels. +- **Middleware + migrations.** Express, Laravel, Spring, Django, Rails middleware; Django, Flask, Laravel, Rails, Prisma, Sequelize migration scripts. +- **Sanitizer-aware adapter strengthening.** Every XXE, header-injection, open-redirect, SSTI, LDAP, XPath, deserialization, crypto, and data-exfiltration adapter rejects bindings when the surrounding source visibly hardens the parser (`disallow-doctype-decl`, `resolve_entities=False`, `libxml_disable_entity_loader`), routes the value through a known encoder (`LdapEncoder.filterEncode`, `escape_filter_chars`, `ldap_escape`), swaps a weak primitive for a CSPRNG (`secrets.token_bytes`, `crypto.randomBytes`, `SecureRandom`), or validates the destination host through an allowlist. Cuts adapter FPs without losing the genuinely dangerous calls. + +### Dynamic verification + +- **`nyx scan --verify`.** Every finding with `Confidence >= Medium` is re-executed inside a sandboxed harness against a curated payload corpus. The verdict (`Confirmed` / `NotConfirmed` / `Inconclusive` / `Unsupported`) lands on `Evidence.dynamic_verdict` and shows up in console output, JSON, SARIF, and the dashboard via a new `VerdictBadge` component on the finding detail page. +- **Backends.** In-process on Linux with `Standard` / `Strict` hardening (namespace unshare, chroot, RLIMIT cap, seccomp filter), in-process on macOS via `sandbox-exec` with a profile-per-policy wrap, Docker with a published image-builder catalogue, and a Firecracker trait stub for future microVM execution. The Docker backend ships native binary support for Rust and Go so harnesses no longer need to drag a toolchain into every image. +- **Language coverage.** Per-language harness emitters for Python, JS/TS, Go, Java, PHP, Ruby, Rust, C, and C++. Stub harness intercepts SQL, HTTP, Redis, and filesystem boundaries so the verdict reflects the sink, not the network. The `JSON_PARSE`, `UNAUTHORIZED_ID`, and `DATA_EXFIL` cap dispatchers are wired into every emitter that ships these caps (Python, JS, TS, Go, Java, PHP, Ruby, Rust), so the verdict pipeline closes the loop on each cap end-to-end rather than per-language piecemeal. +- **Abstract-interpretation and symex sanitizer suppression.** Symbolic execution and the interval/string abstract domain are now consulted at verdict time, so a payload that the static engine would call dangerous but symex can prove never reaches the sink lands as NotConfirmed. +- **Guard-aware verdicts.** When a known input-validation or output-sanitization middleware sits in front of a Confirmed sink (Spring `@PreAuthorize`, Express `helmet`, Nest `@UseGuards`, Django `@permission_classes`, and the per-language registry in `src/dynamic/framework/auth_markers.rs`), the verdict demotes to `ConfirmedWithKnownGuard` and the guard names land on `differential.known_guards`. Authentication-only filters do not trigger the demotion since they do not mitigate injection. +- **Repro bundles.** Every verified finding writes a hermetic bundle to `~/.cache/nyx/dynamic/repro//` with `reproduce.sh`, `expected/{verdict.json,outcome.json,trace.jsonl}`, and a `docker_pull.sh` when the toolchain is pinned in `tools/image-builder/images.toml`. `--verbose` flushes the per-step `VerifyTrace` to stderr for live triage. +- **Real-engine harness paths.** LDAP injection routes through an embedded LDAPv3 BER server, exercised from Java via JNDI `InitialDirContext` and from Python and PHP via pure-stdlib BER clients. XPath injection runs against the live parser in each language: Java `javax.xml.xpath`, PHP `DOMXPath`, JS `xpath` npm, Python `lxml`. `Cap::CRYPTO` lands a `WeakKey` probe across Python, Go, Java, PHP, and Rust that flags sub-2^16 keys produced by non-CSPRNG sources. A new `HeaderSmuggledInWire` oracle predicate catches CRLF smuggling on hand-rolled raw-socket HTTP servers (Python `http.server`, Node `net`, Rust `std::net::TcpListener`) where framework-level CRLF strip cannot intervene. +- **Differential rule v2 and partial confirmations.** A finding confirms when *any* vulnerable payload in the set fires and *every* paired benign control stays clean, replacing the strict pair-wise rule so a single missing control no longer downgrades a confirmable finding. A new `PartiallyConfirmed` verdict marks findings where the sink is reached but the exploit chain does not complete (no marker written, no callback observed), so engine work can ratchet without the tool overstating what it proved. +- **Spec derivation v2.** Every derivation strategy now runs and is scored on flow-step depth, framework binding, cross-file source resolution via `GlobalSummaries`, and payload availability; the highest-scoring candidate wins and the runner-up ranking lands in the trace so engine gaps stay visible. Cross-file seeding walks the call graph (max depth 5) until a `Source` step or framework binding is found. New `EntryKind` adapters auto-recover the entry surface from framework decorators and annotations. + +### Performance + +- **Per-language build pools.** A warm `javac` daemon compiles batched harness sources in one long-lived JVM (Track O headline, Phase 22); Node, PHP, Ruby, Go, Rust, C, and C++ reuse shared module / package / object caches; Python layers a read-only venv per `requirements_hash` with a warmed bytecode cache. Target per-finding harness build: P50 ≤ 200ms hot, ≤ 1.5s cold. Pools self-skip when a toolchain is absent so toolchain-less CI rows stay green. +- **Copy-on-write workdirs.** Per-finding workdir setup uses `clonefile` on macOS and `reflink` / `copy_file_range` on Linux instead of copying every harness file, cutting setup cost to single-digit milliseconds. +- **Cap-routed concurrency lanes.** The verifier worker pool splits into per-cap lanes (`SSRF: 8`, `DESERIALIZE: 2`, `CRYPTO: 1`, and so on) so a slow harness for one cap cannot head-of-line block fast ones. +- **Ship-gate budgets.** Gate 3 holds the with-verify / static-only wall-clock ratio at ≤ 1.5x on `benches/fixtures/`; Gate 6 holds the Java OWASP Benchmark `--verify` run at ≤ 15 min on CI / ≤ 10 min on the dev reference machine. + +### Determinism, policy, telemetry + +- **YAML policy deny list.** `src/policy.rs` is consulted before harness build. Network egress, filesystem writes outside the sandbox root, and process spawns can be denied per-rule; deny decisions land in the trace, redacted via the shared scrubber. +- **Seeded RNG.** `dynamic::rand::SpecRng` is seeded from each `HarnessSpec` hash so two runs of the same spec produce identical payloads. `scripts/check_no_unseeded_rand.sh` audits the tree for unseeded `rand` usage on every CI run. +- **`VerifyTrace` observability.** Every per-step decision (probe selection, payload mutation, oracle check, deny verdict) writes to the trace stream and the repro bundle. +- **Schema-versioned telemetry.** `events.jsonl` carries `schema_version`, `nyx_version`, `corpus_version`, `kind`, and `ts` on every envelope.

Every cap now carries at least one positive / negative / adversarial / unsupported fixture quad per supported language. +- **OWASP Benchmark v1.2 importer.** `tests/eval_corpus/owasp_gt_convert.py` converts the OWASP Java Benchmark expected-results manifest into Nyx ground truth and lands a 16k-line `owasp_benchmark_v1.2.json` for evaluation. +- **NIST SARD importer.** `tests/eval_corpus/sard_gt_convert.py` converts SARD test cases into the same format so cross-dataset recall numbers stay comparable. +- **Evaluation corpus tooling.** `tests/eval_corpus/run_full.sh` runs the Nyx benchmark, OWASP Benchmark, and NIST SARD evaluation sets and writes `tests/eval_corpus/results.json`. `tests/eval_corpus/report.py` and `tabulate.py` produce the per-cap and per-language summary used to track coverage and accuracy. +- **Real-corpus acceptance gates.** `scripts/m7_ship_gate.sh` adds Gate 6 (Java OWASP Benchmark v1.2), Gate 7 (NodeGoat + Juice Shop), and Gate 8 (RailsGoat, DVWA, DVPWA, gosec, RustSec). Each row enforces the per-`(cap, lang)` budget in `tests/eval_corpus/budget.toml` and publishes per-cap precision / recall / confirmed-rate against a committed ground truth. The corpora are not vendored; each row self-skips unless its `NYX__CORPUS` points at a checkout. +- **Per-spec cryptographic canary.** Every oracle marker is now derived from `BLAKE3(spec_hash || run_nonce)` rather than a fixed literal, so markers are unique per finding, collision-resistant against ambient harness output, and never leak to the host. A compile-time audit rejects any new ad-hoc canary. + +### Engine + +- **DB fast-fail preflight.** `Indexer::init` reads the first 16 bytes of any candidate SQLite file and rejects anything without the standard `SQLite format 3\0` magic. Stops a misnamed JSON / text file from corrupting the index path with a SQLite error halfway through migration. +- **Symbolic-execution coverage.** Symex now recognises a wider set of string operations (`substr`, `replace`, `to_lower`, `to_upper`, `trim`, `strlen`) per the value/transfer pipeline, and the abstract-interpretation framework reasons about interval and prefix/suffix string facts during the dynamic verdict pass. + +### CLI + +- **`nyx scan --verify`** (enabled by default in standard builds) and `--backend {auto,process,docker}` select the dynamic-verification harness. `--no-verify` skips verification for a single run without changing config. +- **`nyx scan --harden {standard,strict}`** picks the process-backend hardening profile. `standard` is no-new-privs plus a memory rlimit on Linux. `strict` layers namespace unshare, chroot to the workdir, and a default-deny seccomp filter on Linux, or wraps the harness with `sandbox-exec` on macOS. +- **Patch-validation CI mode.** `--baseline FILE` reads a previous scan's JSON (or a stripped `.nyx/baseline.json` written by `--baseline-write`) and diffs it against the current scan on `stable_hash`, emitting `New` / `Resolved` / `FlippedConfirmed` / `FlippedNotConfirmed` transitions. `--gate {no-new-confirmed,resolve-all-confirmed}` exits non-zero when the diff violates the policy so CI fails the build instead of merging an unreviewed regression. The stripped baseline carries only `stable_hash`, `dynamic_verdict`, `severity`, `path`, and `rule_id`, so persisting it between scans does not leak source. +- **`nyx scan --verify-all-confidence`** drops the Medium cutoff and re-verifies everything. +- **`nyx scan --unsafe-sandbox`** disables hardening (development only, never for CI). +- **`nyx verify-feedback --wrong | --right`** records a correction or confirmation for a finding's verdict in the local telemetry log. +- **`nyx scan --explain-engine`** prints the effective engine configuration and exits without scanning. +- **`nyx surface`** (described above) with `--format {text,json,dot,svg}` and `--build`. + +### Frontend + +- **Surface page** with ELK auto-layout and the shared node-style palette. +- **Verdict badge** on finding detail, plus a dynamic-verdict section that surfaces the verdict, the payload that triggered it, and a link to the repro bundle. +- **Scan compare** gains a dynamic-verdict diff column so two scans can be compared on what was confirmed versus what was downgraded. + +### License + +- **Internal license grants documentation** at `LICENSE-GRANTS.md`.

The loop node is classified against its iterable text, so a source-returning iterable (`req.getCookies()`, `req.getParameterValues("v")`, `$_GET['list']`) lands a `Source` on the loop node and the binding inherits its taint, the same rewrite JS/Python `for … of` / `for … in` already had.

Measures the no-derive +//! dispatch path (chain_step_specs miss, early-exit build/run loops, +//! Inconclusive verdict allocation, severity downgrade). +//! 8. `composite_chain_reverify_stub_confirmed` — same chain shape, stubbed +//! reverifier returning `Confirmed`. Measures the apply-verdict happy path +//! (no severity bucket change). +//! 9. `composite_chain_reverify_top_n_slice` — 5-chain slice with `top_n=3`. +//!

Anchors the +//! apply-verdict allocation cost when the telemetry stability field +//! is populated; a regression that adds per-chain work behind the +//! replay opt-in (e.g. an extra run_chain_steps call leaking out of +//! the live path into the stub layer) shows up here. +//! +//! Wall-clock budget anchors for the composite reverify path: the live +//! process backend stays under 400ms per 3-member chain, the docker +//! backend under 1500ms. Those live-run numbers are covered by the +//! `flask_eval_chain_reverify_populates_dynamic_verdict` integration +//! test in `tests/chain_emission_e2e.rs`; the microbenches here anchor +//! the dispatch + verdict-application overhead so regressions on the +//!

Java harness emitter. +//! +//! Phase 14 (Track B Java vertical) replaces the single legacy `emit` +//! body with dispatch over [`JavaShape`] — the cross product of +//! [`EntryKind`](crate::dynamic::spec::EntryKind) and a lightweight per-file shape detector that inspects +//! the entry file for servlet / Spring / Quarkus annotations, JUnit +//! markers, and `static main(String[])` signatures. +//! +//! Each shape emits a single `NyxHarness.java` that: +//! 1. Reads the payload from `NYX_PAYLOAD` / `NYX_PAYLOAD_B64`. +//! 2. Locates the entry class (default-package, derived from the entry +//! file basename) and invokes its method via the per-shape adapter. +//! 3. Catches all exceptions so the JVM exit shape stays observable. +//! +//! Sink-reachability probe: fixtures explicitly emit +//! `System.out.println("__NYX_SINK_HIT__")` before the actual sink call +//! (same pattern as Rust and Go fixtures). +//! +//! Build step: `prepare_java()` in `build_sandbox.rs` runs `javac` over +//! every `*.java` file in the workdir. Shape fixtures bundle their own +//! annotation / type stubs (e.g. a minimal `HttpServletRequest.java` +//! when the shape needs servlet plumbing) so the JDK can compile the +//! source without pulling Maven dependencies. +//! +//! Payload slot support: +//! - [`PayloadSlot::Param`] — pass payload as `String` first argument +//! (n-th positional for `Param(n)` where `n > 0`). +//! - [`PayloadSlot::EnvVar`] — set a system property before invocation. +//! - [`PayloadSlot::QueryParam`] / [`PayloadSlot::HttpBody`] — surfaced +//! to servlet / Spring / Quarkus adapters as the request body or +//! query parameter value. +//! - [`PayloadSlot::Argv`] — appended to a `String[] args` for +//! `static main` shapes. +//! - Other slots produce [`UnsupportedReason::PayloadSlotUnsupported`]. +//! +//!

Structured sink-probe channel (Phase 06 — Track C.1). +//! +//! Replaces the brittle stdout-substring matching path with a per-run JSON-line +//! channel. Each harness defines a `__nyx_probe` shim (see the per-language +//! emitter in [`crate::dynamic::lang`]) that writes one [`SinkProbe`] record +//! to the channel when the instrumented sink fires. After each sandbox run +//! the runner calls [`ProbeChannel::drain`] and the oracle (see +//! [`crate::dynamic::oracle::oracle_fired`]) evaluates a payload's +//! [`crate::dynamic::oracle::ProbePredicate`] set against the captured args. +//! +//! # Phase 08 extensions (Track C.4 + C.5) +//! +//! - [`ProbeKind`] discriminates a normal sink observation from a crash +//! intercepted by a sink-site signal handler. The handler stamps +//! `ProbeKind::Crash { signal }` onto the probe before re-raising so the +//! oracle can distinguish "the sink crashed under my payload" +//! (Confirmed) from "some unrelated setup code crashed" +//! (Inconclusive(UnrelatedCrash)). +//! - [`ProbeWitness`] carries bounded forensic data — scrubbed env, cwd, +//! payload-bytes prefix, callee, args repr — so downstream repro and +//! chain composition need only the probe file, not a live sandbox. All +//! bounding goes through [`crate::dynamic::policy`]. +//! +//! # Channel medium +//! +//! Currently file-based: one JSON record per line at +//! `/__nyx_probes.jsonl`. The path is exposed to the harness via +//! the `NYX_PROBE_PATH` env var (see [`PROBE_PATH_ENV`]).

Always responds with `200 OK\r\n\r\n` so the +//! harness perceives the call as successful — the goal is to record +//! that the call *happened*, not to faithfully emulate any real +//! origin server. +//! +//! Endpoint: `http://127.0.0.1:{port}`. +//! +//! # Side-channel recording +//! +//! In addition to the on-the-wire listener, [`HttpStub`] publishes a +//! companion log path under the [`HTTP_STUB_LOG_ENV_VAR`] env var +//! (`NYX_HTTP_LOG`). A per-language shim helper +//! (`__nyx_stub_http_record`) appends one record per attempted outbound +//! HTTP call to that file, in the same hash-prefixed detail-then-query +//! format the SQL stub uses. The host merges those records into +//! [`StubProvider::drain_events`] alongside the on-the-wire captures, so +//! a harness whose outbound call never reaches the listener (DNS-mocked, +//! network-isolated sandbox, pre-flight check) still produces an +//! event the oracle can match. +//! +//! # Drop +//! +//! Signals the accept thread to shut down and connects to itself to +//! wake the blocking `accept()`. The thread joins on its next loop +//! iteration; the listener socket is released by the OS.

Minimal in-sandbox LDAP server stub (Phase 06 — Track J.4). +//! +//! The brief calls for "a 200-line Go implementation reused across langs +//! over loopback". This module ships the same idea in Rust: a tiny TCP +//! listener that speaks a one-line text protocol — `SEARCH \n` +//! → `COUNT \nDN \nDN \n…\nEND\n` — so the per-language +//! harness shims can drive a uniform request/response loop without +//! linking a real LDAP client (jldap, python-ldap, ldap_search). +//! +//! Endpoint: `127.0.0.1:{port}` (no scheme; the harness composes +//! `ldap://` itself if it wants). +//! +//! # BER (LDAPv3) dispatch +//! +//! The accept loop peeks the first byte on each connection. When it +//! sees the universal `SEQUENCE` tag (`0x30`) — the leading byte of +//! every well-formed LDAPv3 `LDAPMessage` — it routes the +//! conversation through [`super::ldap_ber`] so a harness using a stock +//! LDAP client (`javax.naming.directory.InitialDirContext`, +//! `python-ldap`, `ldap3`, …) can talk to the stub on the LDAPv3 wire +//! protocol. The plaintext `SEARCH \n` framing remains for +//! every other first-byte value, so the existing tier-(a) harnesses +//! keep round-tripping unchanged. +//! +//! No env var gates this — the dispatch is byte-shape driven so a +//! tier-(a) shim that accidentally emits a leading `0x30` will skip +//! the BER path's failure-mode fallback (the BER decoder bails to +//! `None` on a non-LDAPv3 payload, which closes the connection without +//! corrupting state). +//! +//! # Directory state +//! +//! Three users are provisioned at startup: `alice`, `bob`, `carol`. An +//! incoming search filter is scanned with a tiny RFC 4515 subset: +//! +//! * `(uid=)` matches the user whose `uid` byte-for-byte equals +//! ``. +//! * `(uid=*)` matches every user whose `uid` matches +//! the wildcard skeleton. +//! * Bare `*` inside *any* attribute slot matches every entry. +//! * Boolean wrappers `(&(…)(…))`, `(|(…)(…))` recurse into the inner +//! clauses. +//! +//! Anything outside that subset short-circuits to "match-everything" so +//! adversarial payloads (`*)(uid=*` after the harness's quote-and-paste +//! mistake) cannot accidentally produce a 0-result false negative. +//! +//! # Recording +//! +//! Every served search appends a [`StubEvent`] keyed on `summary = +//! "SEARCH "` and `detail["entries_returned"]` so the oracle's +//! [`crate::dynamic::oracle::ProbePredicate::QueryResultCountGreaterThan`] +//! can satisfy without depending on a `ProbeKind::Ldap` write — the +//! probe path is the primary signal, the stub-event log is the +//! belt-and-braces side channel. +//! +//! # Drop +//! +//!

Per-cap stub providers (Phase 10 — Track D.3). +//! +//! A *stub* is a tiny in-process service that pretends to be the real +//! boundary a sink crosses — a SQL server, an HTTP origin, a Redis +//! cache, a writable filesystem root — so a sink that talks to that +//! boundary can fire under test without depending on a live external +//! service. Each stub exposes: +//! +//! 1. `StubProvider::start` — spin the service up. The constructor of +//! each concrete stub plays this role (e.g. [`SqlStub::start`]); the +//! trait method just hands back the kind for type-erased +//! introspection. +//! 2. [`StubProvider::endpoint`] — the connection string the harness +//! should use (a SQLite DB path, `http://127.0.0.1:port`, a +//! filesystem root, etc.). +//! 3. [`StubProvider::drain_events`] — read every event observed since +//! the last drain. The oracle's +//! [`crate::dynamic::oracle::ProbePredicate::StubEventMatches`] +//! walks these to decide whether a stub-observed effect satisfies +//! a payload's predicate set. +//! 4. `Drop` — tear the service down. The runner relies on the +//! `Arc` drop to release the listening socket / +//! delete the temp filesystem root. +//! +//! # Lifecycle +//! +//! [`StubHarness::start`] spawns exactly the stubs in `kinds` (it does +//! *not* spawn the full set — the performance invariant is that a +//! harness with `stubs_required: []` boots in under 500 ms, so a +//! verifier that needs no stubs touches none of this module). The +//! harness keeps the stubs alive for the duration of a verify run and +//! drops them on scope exit; the runner does not have to know about +//! individual stub types. +//! +//! # Wiring +//! +//! - [`crate::dynamic::spec::HarnessSpec::stubs_required`] is populated +//! at spec-derivation time from [`StubKind::for_cap`]; a SQL sink +//! pulls in [`StubKind::Sql`], an SSRF sink pulls in +//! [`StubKind::Http`], a path-traversal sink pulls in +//! [`StubKind::Filesystem`]. Stubs whose presence is purely +//! opportunistic (e.g. [`StubKind::Redis`]) are not auto-derived from +//! any cap and must be added explicitly by a caller that knows it +//! needs them. +//! - [`crate::dynamic::verify::verify_finding`] starts the required +//! stubs *after* spec derivation and *before* spawning the sandbox, +//! then injects each stub's endpoint into the sandbox env via the +//! well-known [`StubKind::env_var`] name. +//! - Stub events are drained per-payload by the verifier (after each +//! sandbox run) and passed into +//!

OWASP RailsGoat — curated vuln ground-truth manifest (Phase 29, Track R.2). +# +# RailsGoat is an intentionally-vulnerable Ruby on Rails app that maps the +# OWASP Top 10 to concrete controllers/models. Like NodeGoat / Juice Shop +# (Phase 28) it ships no machine-readable per-file vuln labels, so this +# manifest IS the authoritative source: one [[entry]] per known-vulnerable +# location, curated from the project's own tutorial walk-throughs, each with +# a `note` citing why. +# +# tests/eval_corpus/manifest_gt_convert.py turns this into the committed +# ground_truth/railsgoat.json. CI regenerates it against a fresh clone of +# the pinned tag and asserts byte-equality, and the converter HARD-ERRORS on +# any path that no longer exists in the corpus, so a RailsGoat bump that +# moves a controller fails the eval job loudly rather than silently dropping +# recall. Update `pinned_ref` + the paths together when re-pinning. +# +# `cap` is a nyx cap label (tabulate.py); it is aligned with how nyx +# classifies the sink in each file (e.g. a missing ownership check on a +# direct-object lookup surfaces as `auth`, not `unauthorized_id`), so recall +# (did nyx catch the canonical vuln) is meaningful. `path` is relative to +# the RailsGoat clone root, POSIX separators. Lang is inferred from the +# extension (.rb -> ruby).

Misconfiguration cannot brick the sandbox-exec backend. + +## How the seeds get generated + +Run `tools/sb-trace.sh` from a macOS host that has the interpreters +on `$PATH`. The script materialises each `.sb` profile with +`(allow default)` rewritten to `(deny default)`, runs each +per-language probe under `sandbox-exec`, queries +`log show --predicate 'eventMessage CONTAINS "() deny"'` for the +kernel deny records the probe triggered, converts each deny line +into the matching `(allow ...)` rule, appends it to the profile, and +re-runs the probe. The loop stops when an iteration produces no new +denies (the probe ran cleanly under the accumulated allows) or when +the kernel's per-tuple dedup window swallows every remaining record. + +The PID-targeted log query sidesteps the dedup window: each iteration's +probe runs as a new process with a fresh PID, so the kernel emits a +fresh deny record even when the operation tuple repeats. The older +`(trace "")` mechanism is silently ignored on macOS 26+ and is +no longer used. + +Output: + + tools/sb-trace/.allow (committed after hand-review) + +After a run, hand-review each `.allow` seed before committing.

The stripped baseline carries only `stable_hash`, `dynamic_verdict`, `severity`, `path`, and `rule_id`, so persisting it between scans does not leak source. +- **Repository triage in CI.** `nyx scan` now reads the same `.nyx/triage.json` file written by `nyx serve`. Terminal triage states (`false_positive`, `accepted_risk`, `suppressed`, `fixed`) are hidden from CLI output and excluded from `--fail-on` by default, while `--show-suppressed` includes them with `triage_state` / `triage_note` metadata for JSON, SARIF, and console output. - **`nyx scan --verify-all-confidence`** drops the Medium cutoff and re-verifies everything. - **`nyx scan --unsafe-sandbox`** disables hardening (development only, never for CI). - **`nyx verify-feedback --wrong | --right`** records a correction or confirmation for a finding's verdict in the local telemetry log.
