+          ## Corpus Promotion Proposal
+
+          This PR was generated automatically by the weekly corpus-promote workflow.
+          It does **not** auto-merge — a human reviewer must approve each candidate
+          before it can land in `src/dynamic/corpus.rs` (§16.4).
+
+          ### Candidates
+
+          The following payloads were discovered by the internal mutation fuzzer and
+          confirmed via `sink_hit && oracle_fired` against instrumented fixtures:
+
+          PREAMBLE
+
+          for f in $CANDIDATE_FILES; do
+            sidecar="${f}.json"
+            printf -- '- `%s`\n' "$f" >> "$body_file"
+            if [ -f "$sidecar" ]; then
+              printf '  ```json\n' >> "$body_file"
+              cat "$sidecar" >> "$body_file"
+              printf '\n  ```\n' >> "$body_file"

+          done
+
+          cat >> "$body_file" <<'CHECKLIST'
+
+          ### Review checklist
+
+          - [ ] Bytes are a genuine attack vector, not a fixture artifact
+          - [ ] Oracle marker is unique (no collision with other caps)
+          - [ ] `fixture_paths` updated in `src/dynamic/corpus.rs`
+          - [ ] `since_corpus_version` set to next version
+          - [ ] `CORPUS_VERSION` bumped and bump history updated
+
+          _Generated by corpus_promote.yml — do not auto-merge._
+          CHECKLIST

+#   * jsts     (Phase 28 / Track R.1): Gate 7 vs OWASP NodeGoat (Express, .js)

+# Runs on every PR that touches the dynamic verifier (src/dynamic/), the
+# eval-corpus harness (tests/eval_corpus/), or the gate script itself.
+#
+# Each gate enforces, against the committed ground truth:
+#   * verify wall-clock <= 15 min (CI budget; the dev reference is 10 min),
+#   * the per-(cap,lang) budget in tests/eval_corpus/budget.toml,
+#   * per-cap confirmed-rate / precision / recall — hard-gated only for caps
+#     in NYX_*_FLOOR_CAPS (empty by default → published report-only until a
+#     cap Confirms end to end), with destinations >= 40% / >= 0.85 / >= 0.40.
+#
+# No corpus is vendored.  Each is cloned at a pinned ref and cached so reruns
+# skip the clone.  Before the gate runs, the committed ground truth is
+# regenerated from its source against the fresh clone and asserted in sync,
+# and the converter hard-errors on any labelled path missing from the corpus,
+# so a corpus bump that drifts the labels fails the job loudly.

+## [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/<spec_hash>/` 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. PII and secret scrubbing runs on every persisted artefact via `src/utils/redact.rs`.
+- **`NYX_NO_TELEMETRY=1`** disables event persistence outright.
+
+### CVE corpus and ground truth
+
+- **New `Cap` corpora.** Vulnerable + patched fixtures landed for the seven new cap classes (LDAP injection, XPath injection, header injection, open redirect, SSTI, XXE, prototype pollution) plus deserialization, crypto, JSON parsing, unauthorized-id, and data exfiltration. 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_<NAME>_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 <finding_id> --wrong <reason> | --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`. Grant 1 covers Nyctos derived works. The repo stays GPL-3.0-or-later; the grants document scope of internal product licensing.
+
 ## [0.7.0] - 2026-05-11
 
 A focused release that adds seven new vulnerability classes, ships two SSA sidecars for XML and XPath parser hardening, deepens cross-file authorization for FastAPI, trims roughly a thousand auth false positives on Go DAO helpers along with the dominant Hibernate Criteria SQL cluster, and runs a performance pass on the auth extractor, SCCP, and the global summaries map. A `nyx rules list` CLI surfaces the rule registry, the web UI gets a brand-aligned visual refresh, and the CVE corpus grows across Python, PHP, JavaScript, and C.

 - **FastAPI cross-file `include_router` dependency tracking.** `auth_analysis/router_facts.rs` captures per-file router declarations (`<router> = X(deps=[…])`) and `<parent>.include_router(<child_module>.<child_var>)` edges in pass 1, persists them into `GlobalSummaries::router_facts_by_module`, and resolves them into the active file's `AuthorizationModel::cross_file_router_deps` at pass 2 entry. Transitive lifts (grandparent to parent to child) handled by iterative index walk. Module identity is the file basename without `.py`. Closes the airflow execution-API shape where a child router lives in `routes/task_instances.py` and its auth is declared on the parent in `routes/__init__.py`.
 - **FastAPI router-level `dependencies=[...]` propagation.** Module-level `router = APIRouter(dependencies=[Security(...)])` is pre-walked once per file and merged onto every `@<router>.<verb>(...)` route attached in the same file. Closes airflow execution-API routes that re-use a single `ti_id_router` declared once at module scope.
 - **FastAPI `Security(callable, scopes=[...])` recognised distinctly from `Depends(callable)`.** Scoped Security promotes the synthetic `AuthCheck` to `AuthCheckKind::Other` (route-level scope-checked authorization), not Login. New scope-tracking boolean threaded through `expand_decorator_calls` and `extract_fastapi_dependencies`.
-- **Caller-scope IPA: same-file route-handler-to-helper auth lift.** `apply_caller_scope_propagation` walks every non-route helper unit; if its in-file callers are non-empty AND every caller is itself an authorized route handler (route-level non-Login auth check) or already authorized via this same propagation, the caller's checks lift onto the helper as synthetic `is_route_level=true` `AuthCheck`s. Iterated to a small fixpoint so transitive helper chains (route to mid_helper to leaf_helper) are covered. Refuses to authorize helpers with no in-file caller, helpers called from a mix of authorized and unauthorized callers, and helpers called only from un-lifted helpers. Cross-file equivalent deferred. Closes the dominant FastAPI / Django / Flask "route authenticates via decorator/dependency, then delegates to a private helper that performs the sink" FP shape on sentry / saleor / airflow.

 - **Go DAO-helper id-scalar precision pass.** For non-route Go units, a parameter whose declared type is a bounded primitive scalar (`int64`, `uint32`, `string`, `bool`, `byte`, `rune`, `float64`, …) and whose name is id-shaped (`id`, `*Id`, `*_id`, `*ids`) is dropped from `unit.params` before ownership-check evaluation. Real Go HTTP handlers always carry a framework-request-typed param (`*http.Request`, `*gin.Context`, `echo.Context`, `*fiber.Ctx`); per-framework route extractors set `include_id_like_typed=true` so id-shaped path params survive on real routes. Mirrors the existing Python `is_python_id_like_typed_param` filter. Closes ~957 `go.auth.missing_ownership_check` findings on gitea backend DAO helpers (`func GetRunByRepoAndID(ctx, repoID, runID int64)`, `func DeleteRunner(ctx, id int64)`, the entire `models/...` layer where the ownership check sits in the calling route handler) and equivalent shapes in minio / Go ORM codebases.
 - **Bare-callee verb-name fallback gate.** `list(...)`, `filter(...)`, `update(...)`, `create_audit_entry(...)`, `update_coding_agent_state(...)` (no receiver dot at all) no longer classify as `DbMutation` / `DbCrossTenantRead` via the loose verb-name fallback. Real ORM/DB calls carry a receiver (`User.find(id)`, `Model.objects.filter`, `repo.save(x)`); a bare `list(events)` is the Python builtin and `filter(fn, xs)` is `Iterable.filter`. New helper `receiver_is_simple_chain(callee)` requires a non-chained receiver dot. The realtime / outbound / cache prefix dispatches still match by chain root.

 - Short-circuit branch condition CFG nodes now mirror `condition_vars` into `taint.uses`, so `apply_branch_predicates` interns the variable for short-circuit-decomposed validators (`if (x == null || !regex.matcher(x).matches()) throw`). Without this, the per-disjunct cond nodes built via `build_condition_chain` silently no-opped and `x` never reached `validated_must` on the surviving branch.
 - Go `goqu.L(s)` and `goqu.Lit(s)` raw-SQL literal builders modeled as `SQL_QUERY` sinks. Safe siblings (`goqu.I` identifier, `goqu.C` column, `goqu.T` table, `goqu.V` parameterised value, `goqu.SUM`, `goqu.COUNT`, …) stay unlabeled. Gin source list extended with the array-returning siblings of the existing scalar helpers: `c.QueryArray`, `c.GetQueryArray`, `c.PostFormArray`, `c.GetPostFormArray`. Closes CVE-2026-41422 (daptin: `c.QueryArray("column")` → `goqu.L(project)` with the loop variable lifted through `for _, project := range columns`). Vulnerable + patched Go corpus pair under `tests/benchmark/cve_corpus/go/CVE-2026-41422/`.
 - Go `for ident := range iter` def-use lifting. The `range_clause` child of `for_statement` is now consulted when `left`/`right` aren't direct fields of the `for` node, so taint from the iterable reaches the loop binding. Required for the daptin CVE shape above.
+- Java `enhanced_for_statement`, PHP `foreach`, and Ruby `for` def-use lifting, completing the loop forms the Go `range_clause` fix above started. The `Kind::For` def-use arm only knew the JS/Python `left`/`right` pair and Go's `range_clause`; Java carries the binding on `name` and the iterable on `value`, Ruby's `for` on `pattern`/`value`, and PHP's `foreach` keeps both as unnamed children split by the `as` keyword, so none recorded the loop variable as a define and taint on the iterable never reached the binding (`for (Cookie c : req.getCookies()) { … c.getValue() … }` lost the flow at `c`). Each form now folds onto the shared define/use path. Lifts Java OWASP Benchmark recall: path_traversal 0.21 → 0.32, sqli 0.16 → 0.28, cmdi 0.04 → 0.08.
+- Iterable-expression classification for the loop forms above. The loop node is classified against its iterable text, so a source-returning iterable (`req.getCookies()`, `req.getParameterValues("v")`, `$_GET['list']`) lands a `Source` on the loop node and the binding inherits its taint, the same rewrite JS/Python `for … of` / `for … in` already had. Subscript iterables (`$_GET['x']`, `params[:list]`) classify on their base object since sources key on the base name, not the index.
+- Java iterable-returning request accessors modeled as sources: `getParameterValues`, `getParameterMap`, `getParameterNames`, `getHeaders`, `getHeaderNames`. The `getParameter` / `getHeader` matchers are word-boundary suffix matches and never covered the plural collection variants that feed for-each loops (`for (String s : req.getParameterValues("v"))`). The dominant OWASP Benchmark vulnerable-source shape.
 - Rust format-string named-argument lifting (`format!("...{x}...")`, stable since 1.58). Identifiers captured by `{name}` / `{name:fmt-spec}` are pulled into the call's `uses` for known format-style macros: `format`, `print`/`println`, `eprint`/`eprintln`, `write`/`writeln`, `panic`, `format_args`, `assert`/`debug_assert`, `todo`, `unimplemented`, `unreachable`, plus log-crate severity macros (`info`, `warn`, `error`, `debug`, `trace`). Recursive descent through one or two layers of expression wrapping (`format!("{x}").to_owned()`, RHS chained method calls). Without this, taint stopped at the macro boundary. `let q = format!("...{x}...")` carried no `x` because the identifier lives in format-string bytes rather than as a separate AST argument node. Mirrors the Python f-string lifter.
 - Rust CVE corpus extended. CVE-2023-42456, CVE-2024-32884, CVE-2025-53549 vulnerable + patched fixtures under `tests/benchmark/cve_corpus/rust/`.
 - Java lambda shorthand recognised by `extract_param_meta`. `lambda_expression`'s `parameters` field as a bare `identifier` (`cmd -> …`) or as an `inferred_parameters` wrapper around identifiers (`(a, b) -> …`) was not matching the formal_parameter / spread_parameter kinds in `PARAM_CONFIG`, so the lambda appeared parameterless and the SSA pipeline treated its formals as closure captures. Mirrors the JS/TS arrow shorthand path.

 ### Fixed (false positives)
 
+- `cfg-unguarded-sink` parameter-only trace no longer clears a sink argument whose reaching definition is a loop binding. Once the loop variable resolves to its iterable (the def-use lifting above), a `foreach ($param as $v) { sink($v) }` element looked like a bare `sink($p)` wrapper pass-through and the structural finding was dropped. A loop element over a parameter collection is not wrapper plumbing, so the finding survives for loop-bound sink arguments; literal-keyed arrays stay suppressed through `sink_arg_uses_safe_foreach_key`. Keeps the negative case in `fp_guard_php_foreach_safe_literal_keys` firing.
 - Go `unit_has_user_input_evidence` framework-request-name allow-list narrowed for Go. `ctx`, `context`, `info`, `body`, `path`, `payload`, `dto`, `form`, `query` are no longer treated as user-input indicators on Go: in Go these are `context.Context` (cancellation/value-bag from the stdlib) or struct-pointer payload params (`info *PackageInfo`, `opts *FooOptions`), not request bindings. Go HTTP frameworks bind the request to per-framework typed params (`r *http.Request`, `c *gin.Context`, `c echo.Context`, `c *fiber.Ctx`); these arrive at the gate via `RouteHandler` kind or the type-aware param filter below. Stdlib `req` / `request` (the `*http.Request` convention) preserved. Other languages keep the broader allow-list.
 - Go param collection drops `ctx context.Context` and `ctx context.CancelFunc` parameters entirely rather than seeding their names into `unit.params`. Tree-sitter-go's `parameter_declaration` exposes `name` and `type` as named fields; descend only into `name` so type-segment identifiers don't pollute the param-name set (`info *PackageInfo` no longer contributes `PackageInfo`). Together with the allow-list narrowing above, closes ~1900 `go.auth.missing_ownership_check` findings on gitea backend helpers whose only "user-input evidence" was the ubiquitous `ctx context.Context` first param.
 - Ruby controller method visibility + filter-callback gate. Methods marked `private` (bare `private` directive, targeted `private :foo, :bar`, or `protected`) and Rails filter callback targets (`before_action`, `after_action`, `around_action`, their `prepend_*` / `append_*` / `skip_*` siblings, and the legacy `*_filter` aliases) are no longer emitted as `Function` units. Visibility tracking is class-body source-order with two directive forms (bare toggles default visibility, targeted explicitly marks named methods). Block-form filters (`before_action do … end`) carry no symbol arg and are correctly ignored. Closes mastodon / diaspora `rb.auth.missing_ownership_check` flood on `set_X` row-fetch helpers used as `before_action` callbacks.

+## Adding future grants
+
+New grants follow the same format as Grant 1. Append a new section
+(`### Grant N: <recipient name>`) below the existing entries and commit to
+the Nyx repository. Grants are append-only. Revisions land as superseding
+entries with their own date, not as edits to the original.
+
+Grants the Grantor anticipates issuing in the future include:
+
+- Commercial-license SKU grants to individual customers of Nyctos that
+  exceed the PolyForm Small Business threshold. These will be issued
+  per-customer under a separate Nyx Commercial License contract.
+- Stewardship-transition grants if the project is ever handed off (for
+  example, to a foundation). These would be a single grant to the receiving
+  entity.
+
+The Grantor reserves the right to refuse to issue any grant.
+
+---
+
+## What this file is NOT
+
+- It is not a redistribution license. Third parties cannot rely on it to use
+  Nyx outside the public GPL terms.
+- It is not a Contributor License Agreement. `CLA.md` covers contribution
+  terms separately.
+- It is not a public-facing license file. The canonical public license for
+  Nyx is `LICENSE` (GPL-3.0-or-later).

 1. **Pass 1**: parse each file via tree-sitter, build an intra-procedural CFG (petgraph), lower to pruned SSA (Cytron phi insertion over dominance frontiers), and export per-function summaries (source/sanitizer/sink caps, taint transforms, points-to, callees).
 2. **Summary merge**: union all per-file summaries into a `GlobalSummaries` map.
 3. **Pass 2**: re-analyze each file with cross-file context under bounded context sensitivity (k=1 inlining for intra-file callees, SCC fixpoint capped at 64 iterations, and summary fallback for callees above the inline body-size cap). A forward dataflow worklist propagates taint through the SSA lattice with guaranteed convergence. Call-graph SCCs iterate to fixed-point (within the cap) so mutually recursive functions get accurate summaries.

+
+## Verify findings dynamically
+
+Static analysis says a sink is reachable. Dynamic verification tries to prove it. With `--verify` (on by default), Nyx builds a small harness around each Medium-or-higher finding, runs it in a sandbox against a curated payload corpus, and stamps a verdict onto the finding.
+
+```bash
+nyx scan --verify          # build + run a harness per finding (default)
+nyx scan --no-verify       # static analysis only, for fast local loops
+```
+
+A finding is **Confirmed** only when an attacker-controlled payload fires the sink *and* a paired benign control stays clean. That differential rule, plus behavioral oracles (a template that renders `49`, a deserializer that resolves a gadget class, a redirect that leaves the origin), keeps the verifier from confirming on an echoed string. Sinks behind a recognized guard demote to `ConfirmedWithKnownGuard`; sinks reached without a completed exploit chain land as `PartiallyConfirmed`.
+
+Coverage spans 18 verifiable capability classes and 120+ registered adapters across all ten languages (Flask, Django, Express, NestJS, Spring, Rails, Laravel, Gin, Axum, and more), with per-language build pools and copy-on-write workdirs to keep the per-finding cost low. Confirmed findings write a hermetic repro bundle with a `reproduce.sh`. Runs are deterministic: every payload is seeded from the spec hash.
+
+```bash
+# CI: fail the build if a new Confirmed finding appears vs. a baseline
+nyx scan --baseline .nyx/baseline.json --gate no-new-confirmed
+```
+
+Backends: Docker (preferred, network-blocked by default) or an in-process runner with `--harden {standard,strict}`. Full matrix, oracle list, and limitations: [Dynamic verification](https://nyxscan.dev/docs/dynamic.html).

 Taint analysis is interprocedural. Persisted per-function SSA summaries carry per-return-path transforms and parameter-granularity points-to, and call-graph SCCs (including SCCs that span files) iterate to a joint fixed-point. The default `balanced` profile also runs k=1 context-sensitive inlining for intra-file callees. Symex (with cross-file and interprocedural frames) and the demand-driven backwards walk are opt-in.

+# Release checklist: 0.8.0 (dynamic verification)
+
+Maintainer-facing gate for cutting `0.8.0`. The release ships the dynamic
+verifier (Tracks J through S of `.pitboss/play/plan.md`). Sign-off requires
+every row below green, and every CI matrix row green for at least three
+consecutive runs on `master`.
+
+Legend: `[x]` verified locally on the dev reference machine, `[ ]` confirmed
+by CI (must hold for three consecutive runs before tagging).
+
+## Cross-cutting invariants
+
+- [x] `cargo check --no-default-features --features serve` green.
+- [x] `cargo check --features dynamic` green.
+- [x] `cargo nextest run --features dynamic` green: 6545 passed, 0 failed, 16 skipped.
+- [x] Determinism: every payload RNG seeds from `spec.spec_hash`; oracle canaries derive from `BLAKE3(spec_hash || run_nonce)`. `scripts/check_no_unseeded_rand.sh` audits the tree.
+- [x] Observability: each new code path emits a `VerifyTrace` event and a typed `Inconclusive` / `Unsupported` reason.
+- [x] Security: every sink-under-test routes through `src/dynamic/policy.rs` deny rules; no phase weakened the seccomp / `.sb` profile sets.
+- [ ] Performance: default `nyx scan` (no `--verify`) latency does not regress.
+
+## Ship gates (`scripts/m7_ship_gate.sh`)
+
+- [x] Gate 1: static-only scan green on `tests/benchmark/corpus`.
+- [x] Gate 2: `cargo nextest run --features dynamic` green (covers Gate 4 + Gate 5 binaries).
+- [x] Gate 3: with-verify / static-only wall-clock ratio <= 1.5x on `benches/fixtures/`.
+- [x] Gate 4: SARIF schema validation on every dynamic verdict variant.
+- [x] Gate 5: layering boundary test green.
+- [ ] Gate 6: Java OWASP Benchmark v1.2 `--verify` acceptance (wall-clock <= 15 min CI, per-cap precision >= 0.85 / recall >= 0.40, per-`(cap, lang)` budget). Self-skips without `NYX_OWASP_CORPUS`.
+- [ ] Gate 7: NodeGoat + Juice Shop acceptance. Self-skips without `NYX_NODEGOAT_CORPUS` / `NYX_JUICESHOP_CORPUS`.
+- [ ] Gate 8: RailsGoat / DVWA / DVPWA / gosec / RustSec acceptance. Self-skips without the matching `NYX_*_CORPUS`.
+
+Gates 6 through 8 run against real corpora that are not vendored into the repo.
+They are enforced in the `eval` workflow with the corpora cached on the CI
+runner. Locally they self-skip with a clear message.
+
+## CI matrix rows (must be green three runs running)
+
+`ci.yml`:
+- [ ] frontend, rustfmt, clippy-stable, cargo-deny, unused-deps, third-party-licenses
+- [ ] docs-fresh (`nyx-docgen` output committed), rustdoc
+- [ ] rust-beta-build, msrv
+- [ ] rust-stable-test-linux-without-docker, rust-stable-test-linux-with-docker (`cargo nextest run --all-features`)
+
+`dynamic.yml` (each runs `cargo nextest run --features dynamic`):
+- [ ] linux-process-only
+- [ ] linux-with-docker
+- [ ] macos
+
+`eval.yml`:
+- [ ] owasp (Gate 6)
+- [ ] jsts matrix: nodegoat, juiceshop (Gate 7)
+- [ ] polyglot matrix: railsgoat, dvwa, dvpwa, gosec, rustsec (Gate 8)
+
+## Docs and metadata
+
+- [x] `Cargo.toml` version bumped to `0.8.0`; `Cargo.lock` regenerated.
+- [x] `docs/dynamic.md` rewritten: cap x lang matrix, framework adapter table, oracle table, performance budgets, limitations.
+- [x] `README.md` dynamic verification section + docs link.
+- [x] `CHANGELOG.md` `[0.8.0]` entry covers Tracks J through S.
+- [x] Stray version strings updated (README GitHub Action pin, telemetry doc example).
+
+## Known limitations carried into 0.8.0
+
+These are documented in `docs/dynamic.md` and accepted for the MVP. They are
+not release blockers, but the release notes should not overstate the verifier.
+
+- **Guarded-sink over-confirmation (resolved on `dynamic`).** The synthesized
+  harness now drives the finding's enclosing entry function when one is
+  derivable, routing the payload to the tainted parameter, so a guard that
+  lives in the caller (a `Object.create(null)` merge target, an allowlisting
+  `resolveClass`, a const-name check before `Marshal.load`) runs first and
+  participates in the verdict. The build-time entry-vs-sink choice is recorded
+  on the verify trace as `entry_invocation`. When no enclosing entry can be
+  derived the harness falls back to driving the sink directly, which can still
+  over-confirm a guard it never executes. On the in-house fixture set the
+  verify scan now confirms the 8 genuine vulnerabilities and reads
+  `NotConfirmed` on all 4 negative-control files.
+- **In-house confirmed rate is modest.** A `--verify` scan of
+  `tests/dynamic_fixtures` (process backend) lands 8 Confirmed / 15
+  NotConfirmed / 115 Inconclusive / 137 Unsupported of 275. The Unsupported
+  bulk is `SoundOracleUnavailable` (ENV_VAR / SHELL_ESCAPE / URL_ENCODE source
+  and sanitizer caps, correct by design); the Inconclusive bulk is
+  `SpecDerivationFailed` on benign and scaffolding fixtures with no derivable
+  flow. The authoritative confirmed / precision / recall numbers come from the
+  real-corpus gates (6 through 8), which require the corpora.
+- **Real-corpus gates unverified locally.** Gates 6 through 8 self-skip without
+  `NYX_*_CORPUS`. The >= 40% confirmed and >= 0.85 precision targets are
+  enforced only in the `eval` workflow.
+
+## Tag
+
+- [ ] Three consecutive green CI runs on `master` confirmed.
+- [ ] Real-corpus gates (6 through 8) green in the `eval` workflow with corpora wired.
+- [ ] `git tag v0.8.0` and push; `release-build.yml` publishes the binaries and `SHA256SUMS`.

+//! Dynamic verification benchmarks (§8.4).
+//!
+//! Tracks the per-scan cost anchors:
+//!
+//! 1. `harness_build_cold` — fresh workdir, spec → BuiltHarness (source gen + disk write).
+//! 2. `harness_build_warm` — same spec, workdir already staged (file write skipped).
+//! 3. `sandbox_run_payload` — single payload run via process backend against
+//!    sqli_positive.py (subprocess + settrace overhead, no networking).
+//! 4. `docker_image_build` — cold image pull/build for the python:3-slim base.
+//! 5. `docker_exec_warm` — `docker exec` into a running container (no cold start).
+//! 6. `docker_payload_cost` — per-payload sandbox cost via docker backend end-to-end.
+//! 7. `composite_chain_reverify_dispatch` — `reverify_top_chains` on a
+//!    synthetic 3-member chain with no member diags. 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`.
+//!    Measures the slice traversal cost so a regression that walks the full
+//!    slice instead of the prefix is visible.
+//! 10. `composite_chain_reverify_replay_stable` — same chain shape as
+//!     `stub_confirmed`, but with `VerifyOptions::replay_stable_check=true`
+//!     and a stub that stamps `replay_stable=Some(true)`. 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
+//! API-shape half land in the criterion baseline.
+//!
+//! Baselines committed to `benches/dynamic_bench_baseline.json`.
+//! Run: `cargo bench --features dynamic -- dynamic`
+//!
+//! Docker benchmarks are no-ops when docker is unavailable (skipped, not failed).

+# Dynamic verification
+
+Static analysis tells you a sink is reachable from a source. Dynamic
+verification tries to prove it. When verification is on, Nyx builds a small
+harness around each finding, runs it in a sandbox against a curated payload
+set, and stamps the result onto `evidence.dynamic_verdict`.
+
+It is a second signal, not a replacement for review. A `Confirmed` verdict
+means Nyx triggered the sink in its harness with an attacker-controlled
+payload and proved the benign control stayed clean. `NotConfirmed` means the
+harness ran but nothing fired. Neither verdict closes a finding on its own.
+
+Default Nyx builds include the `dynamic` feature. Custom
+`--no-default-features` builds run static-only unless rebuilt with
+`--features dynamic`.
+
+## How confirmation works
+
+Every cap that can be verified ships a curated corpus of payload pairs: at
+least one vulnerable payload and one benign control. The verifier runs both
+through the same harness and compares.
+
+- The vulnerable payload must fire the sink. A payload "fires" when an
+  oracle predicate matches the observed behavior, not when a string appears
+  in the output.
+- The benign control must stay clean. It exercises the same code path with a
+  value that a correct implementation handles safely.
+
+A finding is `Confirmed` only when at least one vulnerable payload fires and
+every paired benign control stays clean. This differential rule is what keeps
+the verifier from confirming a finding just because the harness echoed an
+input.
+
+Oracles are behavioral, scoped to the cap:
+
+| Cap | Oracle | What it observes |
+| --- | --- | --- |
+| Command/code injection | stub event | the harness's exec boundary saw the injected command |
+| SQL injection | stub event | the SQL boundary saw the injected clause |
+| SSRF, data exfil | outbound host | the request left for a host outside the allowlist |
+| Path traversal | stub event | the filesystem boundary opened a path outside the root |
+| Template injection | template eval | `{{7*7}}` rendered as `49`, not echoed as text |
+| Deserialization | gadget marker | a non-allowlisted class was resolved during decode |
+| XXE | entity expansion | an external entity was expanded by the parser |
+| LDAP / XPath injection | result count | the malicious filter returned more rows than the benign one |
+| Header / CRLF | header split | an injected `\r\n` split or added a response header |
+| Open redirect | redirect host | the `Location` header pointed off-origin |
+| Prototype pollution | canary touch | a property write reached `Object.prototype` |
+| Weak crypto | key entropy | the produced key fit inside a 16-bit search space |
+| JSON parse abuse | parse depth | the parser accepted a depth past its limit |
+| IDOR | ownership cross | the read crossed from the caller's id to another owner's |
+
+Every canary is derived per-run from `BLAKE3(spec_hash || run_nonce)`, so it is
+unique per finding, collision-resistant against ambient harness output, and
+never appears on the host.
+
+## Running it
+
+```bash
+nyx scan                      # verifies Medium and High confidence findings
+nyx scan --no-verify          # static analysis only
+nyx scan --verify             # explicit form of the default behavior
+nyx scan --verify-all-confidence   # also verify Low-confidence findings
+```
+
+Use `--no-verify` for fast local checks or editor workflows. Keep
+verification on for CI when scan time allows it. `--verify-all-confidence` is
+slower and noisier; reach for it when tuning payloads or chasing coverage.
+
+## Verdicts
+
+| Status | Meaning |
+| --- | --- |
+| `Confirmed` | A vulnerable payload fired the sink and every benign control stayed clean. |
+| `PartiallyConfirmed` | The sink was reached but no oracle marker was observed. The exploit chain did not complete. Treat as a strong lead, not a proof. |
+| `NotConfirmed` | The harness ran but no payload fired. The path is likely infeasible or the corpus does not cover this shape. The original finding stays open until reviewed. |
+| `Inconclusive` | Nyx could not finish the check. Carries a typed reason (build failed, spec derivation failed, sandbox error, policy denied, and others). |
+| `Unsupported` | Nyx did not attempt the finding. Carries a typed reason (language unsupported, entry kind unsupported, no payloads for cap, confidence below threshold, no sound oracle). |
+
+When a `Confirmed` sink sits behind a recognized input-validation or
+output-sanitization guard (Spring `@PreAuthorize`, Express `helmet`, Nest
+`@UseGuards`, Django `@permission_classes`), 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.
+
+`PartiallyConfirmed` is deliberate. It marks the cases where engine work can
+ratchet without the tool overstating what it proved.
+
+## Capability coverage
+
+Caps split into two groups. Data-style injection (SQL, command, path,
+SSRF, XSS) uses language-neutral payload bytes (`' OR 1=1--`, `../../etc/passwd`,
+a callback URL), so the harness emitter for any language can carry them. The
+caps below have language-specific payloads (a Java gadget chain is not a
+Python pickle), so each language is curated on its own.
+
+A checkmark means a tuned per-language payload set ships for that cell. Cells
+without a checkmark in the data-style rows still run, falling back to the
+language-neutral payload union.
+
+| Cap | Py | JS | TS | Java | PHP | Ruby | Go | Rust | C | C++ |
+| --- | -- | -- | -- | ---- | --- | ---- | -- | ---- | - | --- |

+
+## Framework adapters
+
+Adapters bind a function to its external entry surface so the harness can
+drive the real entry point (an HTTP request through the framework, a published
+message, a scheduled fire) instead of calling the function in isolation.
+Middleware and request validation participate in the verdict that way.
+
+| Language | HTTP routers | Other surfaces |
+| --- | --- | --- |
+| Python | Flask, Django, FastAPI, Starlette | Jinja2, pickle, LDAP, Celery, Kafka, SQS, Pub/Sub, RabbitMQ, Django Channels, Socket.IO, Django middleware, Django + Flask migrations |
+| JavaScript | Express, Koa, NestJS, Fastify | Handlebars, Apollo + Relay GraphQL, lodash.merge + JSON deep-assign, Socket.IO, SQS, Express middleware, Knex + Prisma + Sequelize migrations |
+| TypeScript | NestJS | Object.assign + lodash.merge + JSON deep-assign |
+| Java | Spring, Quarkus, Micronaut, Jakarta Servlet | Thymeleaf, ObjectInputStream, Spring LDAP, Kafka, SQS, RabbitMQ, Quartz, Spring middleware, Flyway + Liquibase migrations |
+| PHP | Laravel, Symfony, CodeIgniter | Twig, unserialize, LDAP, Laravel middleware, Laravel migrations |
+| Ruby | Rails, Sinatra, Hanami | ERB, Marshal, Sidekiq, ActionCable, Rails middleware, Rails migrations |
+| Go | Gin, Echo, Fiber, Chi | gqlgen GraphQL, NATS, Pub/Sub, go-migrate migrations |
+| Rust | Axum, Actix, Rocket, Warp | Juniper GraphQL, Refinery + SQLx migrations |
+| C / C++ | none | argv / stdin entry only |
+
+Adapters are sanitizer-aware. An XXE, header-injection, open-redirect, SSTI,
+LDAP, XPath, deserialization, crypto, or data-exfil adapter declines the
+binding when the surrounding source visibly hardens the call: a parser set to
+`disallow-doctype-decl` or `resolve_entities=False`, a value routed through
+`LdapEncoder.filterEncode` or `escape_filter_chars`, a weak primitive swapped
+for `secrets.token_bytes` or `crypto.randomBytes` or `SecureRandom`, or a
+redirect host checked against an allowlist. That cuts adapter false positives
+without losing the genuinely dangerous calls.
+
+## Entry points
+
+The verifier knows how to stand up these entry shapes:
+
+`Function`, `HttpRoute`, `CliSubcommand`, `LibraryApi`, `ClassMethod`,
+`MessageHandler`, `ScheduledJob`, `GraphQLResolver`, `WebSocket`,
+`Middleware`, `Migration`.
+
+`ClassMethod` walks constructor parameters and builds the receiver, preferring
+a default constructor and otherwise stubbing dependencies (`MockHttpClient`,
+`MockDatabaseConnection`, `MockLogger`) up to a bounded depth. `MessageHandler`
+boots an in-sandbox broker stub on loopback and publishes the payload.
+`Migration` runs under a database-in-test-mode profile with no real
+connection. An entry kind a language emitter does not yet support produces
+`Inconclusive(EntryKindUnsupported)` with a hint, never a silent skip.
+
+## Sandbox backends
+
+```bash
+nyx scan --backend auto      # docker when available, else process (default)
+nyx scan --backend docker    # require docker
+nyx scan --backend process   # run on the host with weaker isolation
+nyx scan --unsafe-sandbox    # alias for --backend process
+nyx scan --harden strict     # full process-backend lockdown
+```
+
+Docker is the preferred backend. It mounts only the entry file's directory and
+blocks outbound network by default. Nyx binds a loopback OOB listener at scan
+start for callback-style payloads (SSRF, blind SSTI). When the bind succeeds,
+Docker switches to bridge networking with a host-gateway route so the harness
+can reach the listener; OOB payloads are skipped if the bind fails.
+
+The process backend runs on the host. It is useful for development and
+machines without Docker, and it does not provide the same isolation. Hardening
+profiles apply to it:
+
+- `standard` (default): no-new-privs plus a memory rlimit on Linux. No
+  `sandbox-exec` wrap on macOS.
+- `strict`: namespace unshare, chroot to the workdir, and a default-deny
+  seccomp filter on Linux; `sandbox-exec -f <cap>.sb` on macOS. Opt-in,
+  because interpreted Linux harnesses can SIGSYS until the per-language seccomp
+  allowlists are widened.
+
+Every sink under test passes through the policy deny rules in
+`src/dynamic/policy.rs` before the harness builds. Network egress, writes
+outside the sandbox root, and process spawns can be denied per rule, and the
+deny decision lands in the trace.
+
+## Performance
+
+Verification adds a harness build and a sandbox run per finding. Two pieces of
+infrastructure keep that affordable at corpus scale.
+
+Per-language build pools reuse a warm toolchain across findings instead of
+cold-starting one each time. Java runs a long-lived `javac` daemon; Node, PHP,
+Ruby, Go, Rust, C, and C++ reuse shared module, package, and object caches;
+Python layers a read-only venv with a warmed bytecode cache. The target is a
+P50 harness build at or under 200ms hot and 1.5s cold, with an OWASP-scale run
+finishing in 10 minutes on the dev reference machine.
+
+Copy-on-write workdirs (`clonefile` on macOS, `reflink` or `copy_file_range`
+on Linux) replace per-finding file copies, and the worker pool routes findings
+into per-cap concurrency lanes so a slow `DESERIALIZE` harness does not block
+fast `SSRF` ones.
+
+The CI ship gate holds the with-verify to static-only wall-clock ratio at or
+under 1.5x on `benches/fixtures/`. If a change pushes it past that, the gate
+fails.
+
+## Repro artifacts
+
+Confirmed findings write a hermetic bundle:
+
+```text
+~/.cache/nyx/dynamic/repro/<spec_hash>/
+```
+
+The bundle carries the harness spec, payload, expected output, trace, and a
+`reproduce.sh`. When the toolchain is pinned in `tools/image-builder/images.toml`
+it also writes a `docker_pull.sh`.
+
+```bash
+cd ~/.cache/nyx/dynamic/repro/<spec_hash>
+./reproduce.sh
+./reproduce.sh --docker
+```
+
+Use the Docker form when the bundle records a pinned image or when host
+toolchains differ from the original run.

+| Field | Meaning |
+| --- | --- |
+| `schema_version` | Event schema version. Readers reject mismatches. |
+| `nyx_version` | Version of the Nyx binary that wrote the event. |
+| `corpus_version` | Payload corpus version used for the verdict. |
+| `kind` | `verdict` or `rank_delta`. Feedback rows use an `event: "verify_feedback"` field instead. |
+| `ts` | Write time in RFC 3339 format. |
+| `finding_id` | Stable finding identifier. |
+| `spec_hash` | Hash of the harness spec. |
+| `lang` | Language slug, or `unknown` when spec derivation failed. |
+| `cap` | Sink capability, such as `SQL_QUERY` or `CODE_EXEC`. |
+| `status` | `Confirmed`, `PartiallyConfirmed`, `NotConfirmed`, `Inconclusive`, or `Unsupported`. |
+| `inconclusive_reason` | Present when `status` is `Inconclusive`. |
+
+If the schema changes, move or delete the old `events.jsonl` before reading it
+with the new binary. Programmatic readers should use
+`crate::dynamic::telemetry::read_events(path)`.
+
+### Sampling
+
+`[telemetry]` in `nyx.toml` controls event retention:
+
+```toml
+[telemetry]
+keep_all_confirmed    = true
+keep_all_inconclusive = true
+sample_rate_other     = 1.0
+```
+
+`sample_rate_other` accepts `0.0` to `1.0` and applies to `NotConfirmed` and
+`Unsupported` verdicts. The decision is deterministic for a given `spec_hash`.
+Confirmed, Inconclusive, and rank-delta events are always kept by default.
+
+Set `NYX_NO_TELEMETRY=1` to disable event writes.
+
+## Feedback
+
+To record a bad verdict:
+
+```bash
+nyx verify-feedback <finding_id> --wrong "reason"
+```
+
+Feedback is written to the local event log. Nyx does not upload it.
+
+## Determinism
+
+Every random source is seeded from the spec hash, so two runs of the same spec
+produce identical payloads and identical verdicts. `scripts/check_no_unseeded_rand.sh`
+audits the tree for unseeded `rand` usage on every CI run.
+
+## Limitations
+
+- The harness drives the finding's enclosing entry function when one is
+  derivable, routing the payload to the tainted parameter, so a guard in the
+  code around the sink (a merge target built with `Object.create(null)`, an
+  `ObjectInputStream` subclass whose `resolveClass` enforces an allowlist, a
+  const-name check before `Marshal.load`) runs first and participates in the
+  verdict. The build-time choice is recorded on the verify trace as
+  `entry_invocation` (`mode=entry_function` or `mode=direct_sink`). When no
+  enclosing entry can be derived the harness falls back to driving the sink
+  directly, and that fallback can over-confirm a guard it never executes. Read
+  a `direct_sink` `Confirmed` as "this sink is reachable and fires on attacker
+  input," not "this exact code path has no in-line mitigation." Framework-level
+  guards (auth middleware, helmet) are also recognized and demote to
+  `ConfirmedWithKnownGuard`.
+- Per-language payload curation is uneven. Command and code injection ship for
+  all ten languages; the classic data-style injection caps (SQL, path
+  traversal, SSRF, XSS) ship a tuned set for Rust and fall back to a
+  language-neutral payload union elsewhere; the framework-specific caps are
+  curated for the languages where they occur. The matrix above is the precise
+  state.
+- A `NotConfirmed` verdict is not a clean bill. It means the harness did not
+  fire, which can be an infeasible path or a corpus that does not cover the
+  shape. Keep reviewing `NotConfirmed` findings.
+- The process backend is weaker isolation than Docker. Use `--backend docker`
+  or `--harden strict` for untrusted code, and never `--unsafe-sandbox` in CI.
+- Real-corpus acceptance rows (OWASP Benchmark, NodeGoat, Juice Shop, and the
+  polyglot set) self-skip in CI unless the corresponding `NYX_*_CORPUS`
+  environment variable points at a checkout. They are not vendored into the
+  repo.
+- C and C++ have no framework adapters. Findings in those languages verify
+  through `argv` and `stdin` entry points only.
+
+## Browser UI
+
+`nyx serve` shows dynamic verdicts on finding detail pages, uses them in
+ranking, and can compare verdict changes between saved scans. See
+[Output formats](output.md) for the `dynamic_verdict` schema.

 **Pass 1, per file.** Tree-sitter parses the file. Nyx builds an intra-procedural control-flow graph, lowers it to SSA, and extracts a summary per function describing what that function does at the boundary: which arguments flow to sinks, which sources it reads from, which sinks it calls, what taint it strips, what it returns. Summaries are persisted to SQLite ([`src/summary/`](https://github.com/elicpeter/nyx/tree/master/src/summary/), [`src/database.rs`](https://github.com/elicpeter/nyx/blob/master/src/database.rs)).

 A separate **field-sensitive points-to** pass tracks abstract locations down to the field level, so `c.mu.Lock()` is a lock on `Field(c, mu)` rather than on `c` as a whole. That distinction is what lets the resource-lifecycle and taint passes tell `obj.field = tainted; sink(obj.other_field)` apart from the conservative whole-variable approximation. Subscript reads and writes (`arr[i]`, `map[k] = v`) lower to synthetic `__index_get__` / `__index_set__` calls so the same container model handles them. Set `NYX_POINTER_ANALYSIS=0` to fall back to the pre-pointer-pass behaviour for baseline comparison.
 
+**Dynamic verification.** After ranking and dedupe, default builds verify Medium and High confidence findings unless `--no-verify` or `scanner.verify = false` is set. The verifier derives a small harness from the finding, runs it in a sandbox against curated payloads, and stores the result on `evidence.dynamic_verdict`. `Confirmed` means a vulnerable payload fired and its benign control stayed clean. `NotConfirmed` means the harness ran but did not fire, not that the finding is closed.

-## Baseline schema
-
-```json
-{
-  "_doc": "...",
-  "target": "cal_com",
-  "clone_url": "https://github.com/calcom/cal.com",
-  "exercises_recall_items": [1, 5, 6, 7],
-  "captured_against": "real-scan @ <sha>",
-  "captured_on": "YYYY-MM-DD",
-  "pinned_commit": "<sha>",
-  "findings": [
-    {
-      "rule_id": "taint-unsanitised-flow",
-      "path_suffix": "packages/...",
-      "line": 130,
-      "severity": "High",
-      "verdict": "TP" | "FP" | "needs_review",
-      "note": "..."
-    }
-  ]
-}
-```
-
-The diff key is `(rule_id, path_suffix, line)`. The `verdict` field
-must be one of `TP`, `FP`, or `needs_review`; unknown verdicts are
-rejected by the schema test.
-
-## Usage
-
-### Diff a fresh scan against the frozen baseline
-
-```bash
-scripts/validate_recall.sh cal_com /path/to/cal.com
-```
-
-Output is a JSON object `{ added, removed, unchanged, *_total }`
-keyed by `rule_id`. Use this to spot intentional recall lift
-(`added`) and regressions (`removed`).
-
-### Refresh the baseline after an intentional recall lift
-
-```bash
-scripts/validate_recall.sh cal_com /path/to/cal.com --capture
-```
-
-This overwrites `tests/recall_targets/cal_com.json` with the current
-scan output. Every finding is re-marked `verdict: "needs_review"`;
-hand-label `TP`/`FP` afterwards as you triage.
-
-### Schema-validity check
-
-```bash
-cargo test --release --test recall_gaps -- --ignored validate_real_world_targets
-```
-
-Loads each per-target JSON, asserts the required keys exist, and
-asserts every finding carries a valid verdict label.
-
-## Refresh procedure
-
-1. Clone or pull the target repo into `~/oss/<target>` (or wherever).
-2. Build nyx: `cargo build --release`.
-3. Run the diff in plain mode to see what changed:
-   `scripts/validate_recall.sh <target> ~/oss/<target>`.
-4. If the lift is intentional, recapture:
-   `scripts/validate_recall.sh <target> ~/oss/<target> --capture`.
-5. Spot-check a handful of new findings. Open the file at
-   `path_suffix:line` and confirm the source-to-sink flow is real.
-   Hand-label them `TP`/`FP`.
-6. Commit the updated `tests/recall_targets/<target>.json`.
-

-The `cal_com` capture used commit `d278d6c9bc535bf3f2c6ba0607654f78dd74d6ee`
-(`refactor: remove dead insights references (#29029)`). The 4 `FP`
-labels are `ts.crypto.math_random` hits inside `apps/web/playwright/`
-test fixtures, which are not a security context.
-
-The other three targets ship as placeholders (empty `findings`).
-Nobody has cloned them locally yet. Run `validate_recall.sh
-<target> <clone> --capture` to populate. The schema test still passes
-because `[]` is a valid `findings` array with zero entries to check.
-
-## Perf baseline
-
-The frozen JS-target perf snapshot lives in
-`tests/recall_targets/perf_after.txt`. Compare against the
-`captured_against` snapshot in `tests/recall_gaps_baseline.json`
-(`corpus_finding_lines.findings_total` = 1121, captured at master
-`ea82ea98`). The acceptance bar: scanner throughput on the existing
-`tests/fixtures/` corpus must regress by no more than 15%. Future
-recall work uses the same corpus and the same record file to measure
-its own perf delta.
-
-## Cross-language runbook
-
-The JS-target baselines above only cover JS/TS. Cross-language
-baselines mirror that work against real-world non-JS targets so
-multi-language engine changes can be measured against actual code,
-not just synthetic fixtures. Per-lang baselines live under
-`tests/recall_targets/xlang/<lang>/<target>.json` and the runner
-accepts a `--lang` flag to select the target set.

-Captures dated `2026-05-09` (UTC). Counts are deduplicated tuples
-`(rule_id, path_suffix, line)`. Duplicate raw findings collapse on
-the diff key, so the schema-test count and diff-mode `unchanged_total`
-may differ from the `findings | length` total by a handful of
-duplicate sites. The diff key is what matters for regression
-detection.
-
-### Per-lang TP/FP splits
-
-Every captured finding ships with `verdict: "needs_review"` from
-`--capture`. Hand-triage is bounded but pending; none of the cross-
-language captures are sweep-labelled yet. Use the per-lang dominant
-rule_id clusters above as the priority queue:
-
-- **PHP**: `cfg-unguarded-sink` and `taint-prototype-pollution` are
-  the FP-dominant clusters across drupal / nextcloud / phpmyadmin
-  (CMS routing + JS object construction). `php.deser.unserialize` is
-  the highest-value TP cluster on joomla (17) and drupal (83). See
-  `project_realrepo_joomla.md` 2026-05-03 for the magic-method
-  passthrough fix that already filters one shape.
-- **Java**: `taint-unsanitised-flow` (61) and `state-resource-leak`
-  (60) are openmrs's leading clusters. The JPA Criteria-API fix
-  already absorbed the `cfg-unguarded-sink` cluster (216 to 24);
-  remaining Hibernate / Spring resource-management FPs are the next
-  triage target.
-- **Python**: `cfg-unguarded-sink` (252) on airflow is dominated by
-  Airflow's scheduler / DB plumbing; `py.auth.token_override_*`
-  (83) and `py.auth.missing_ownership_check` (61) are the auth-rule
-  noise typical of an admin/operator codebase.
-- **Go**: gin's 20 findings are mostly test-corpus artifacts
-  (`gin_test.go`, `routes_test.go`); 4 of 4 `go.transport.insecure_skip_verify`
-  hits are inside `gin*_test.go` and are legitimate test setup.
-- **Rust / Ruby**: placeholder. Capture once a local clone exists.
-
-### `--lang` runner usage
-
-```bash
-# diff mode (default)
-scripts/validate_recall.sh --lang php drupal /Users/me/oss/drupal
-scripts/validate_recall.sh --lang java openmrs /Users/me/oss/openmrs
-
-# capture / refresh
-scripts/validate_recall.sh --lang go gin /Users/me/oss/gin --capture
-```
-
-Output is the same `{ added, removed, unchanged, *_total }` JSON shape
-as the JS-target diff. The diff key is `(rule_id, path_suffix, line)`.

-### Sandbox-capture caveat
-
-Pitboss implementer agents run sandboxed without network egress, so
-target repos that are not already present under `~/oss/` ship as
-placeholders (`pinned_commit: "unknown"`, `findings: []`). The
-current cross-language baselines cover php / java / python / go
-(every target whose repo was already cloned locally) and ship
-placeholders for `rust/axum`, `ruby/rails`, and `python/flask`. The
-schema test in `validate_real_world_targets` passes against
-placeholders because `[]` is a valid `findings` array.

-## What lives where (quick reference)

-- Targets list and recall-item mapping in this file.
-- Per-target JS findings under `tests/recall_targets/<target>.json`.
-- Per-target cross-lang findings under `tests/recall_targets/xlang/<lang>/<target>.json`.
-- Diff/capture runner at `scripts/validate_recall.sh` (accepts `--lang`).
-- Schema-validity test at `tests/recall_gaps.rs::validate_real_world_targets`.
-- Corpus regression baseline at `tests/recall_gaps_baseline.json`.
-- Perf records at `tests/recall_targets/perf_after.txt` (JS-target
-  snapshot) and `tests/recall_targets/perf_after_xlang.txt`

-`nyx serve` enforces three things at the HTTP layer ([`src/server/security.rs`](https://github.com/elicpeter/nyx/blob/master/src/server/security.rs)):
+`nyx serve` enforces three things:
 
-1. **Loopback bind only.** `--host` and `[server].host` are clamped to `127.0.0.1`, `localhost`, or `::1`. Any other value is refused at startup with `Nyx serve only binds to loopback addresses; refused host '<value>'`.
-2. **Host-header check.** Every request must carry a `Host` header that matches the bound address and port. Missing or mismatched headers get a `400 invalid Host header`. Defends against DNS rebinding.

Any other value is refused at startup with `Nyx serve only binds to loopback addresses; refused host '<value>'` ([`src/commands/serve.rs`](https://github.com/elicpeter/nyx/blob/master/src/commands/serve.rs)).

Defends against DNS rebinding ([`src/server/security.rs`](https://github.com/elicpeter/nyx/blob/master/src/server/security.rs)).
 3. **CSRF on mutations.** `POST` / `PUT` / `PATCH` / `DELETE` requests must carry a per-process CSRF token in the `x-nyx-csrf` header. The token is generated once when the server starts and exposed at `GET /api/health` so the embedded SPA can read it. Cross-origin mutations are rejected before the CSRF check via the `Origin` header.
 
 If you forward the port over SSH or expose it through a reverse proxy, the host-header check will reject the request because the `Host` won't match `localhost:9700`. That's the intended behaviour. Don't do this without a deliberate reason; the loopback bind is part of the security model.

 It's a Nyx-finding-pressure metric, not a security audit. Score 100 means Nyx didn't find anything under its current rules and language coverage; it doesn't certify the absence of vulnerabilities. The score doesn't see runtime config, IAM, secret stores, dependency CVEs, or anything outside the source tree being scanned. A repo of mostly Kotlin (where Nyx coverage is thin) will score artificially well because most of the code never gets evaluated.
