+### Dynamic verification overhaul
+
+End-to-end delivery of the surface map + chain composer + dynamic verifier work tracked in the pitboss plan.  Together these three pieces turn a static finding list into a verified attack-surface graph and post the published headline metrics in `docs/dynamic.md`.
+
+- **Attack-surface map.** `nyx surface` (Phase 23) emits a JSON / web-renderable graph of every entry point, datastore, external service, and dangerous local sink the project exposes.  Built from the existing pass-1 summaries (no second walk of the codebase) and persisted alongside the index so the frontend can reload without rescanning.  Per-framework router probes cover Flask, FastAPI, Django, Express, Koa, Spring, Servlet, Quarkus, Gin, Actix, Axum, Rails, and Laravel.
+- **Chain composer.** `nyx scan` (Phase 24–26) now lifts taint findings into `ChainFinding` records that connect a route entry point to a downstream sink via the call graph + surface map.  The lattice composer scores (impact × evidence) per chain and the top-N are queued for composite reverification.  Output is wired into the `findings.json` / SARIF emitters and the `nyx serve` UI so chains rank above isolated findings.
+- **Dynamic verifier.** Every `Confidence >= Medium` finding (Phase 06–22) is now executed against a curated payload corpus inside a sandboxed harness, with the verdict (`Confirmed` / `NotConfirmed` / `Inconclusive` / `Unsupported`) stamped onto `Evidence.dynamic_verdict`.  Backends: in-process (`Standard` / `Strict` hardening), docker (Phase 19 image-builder catalogue), firecracker stub (Phase 20 trait).  Per-language emitters cover Python, JS/TS, Go, Java, PHP, Ruby, Rust, C, and C++.  Curated payload corpus, abstract-interpretation + symex sanitizer suppression (Phase 17–22), stub harness with SQL / HTTP / Redis / filesystem boundary intercepts (Phase 10), and reproducible repro bundles at `~/.cache/nyx/dynamic/repro/<spec_hash>/` (Phase 27–28).
+- **Telemetry + repro.** `events.jsonl` is now schema-versioned (envelope: `schema_version`, `nyx_version`, `corpus_version`, `kind`, `ts`).  Repro bundles are hermetic (Phase 28): every bundle emits `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`.  PII / secret scrubbing runs on every persisted artefact via `src/utils/redact.rs`.
+- **Determinism + policy.** `src/policy.rs` exposes a YAML-driven deny list (Phase 30) consulted before harness build, with deny-decision excerpts redacted via the same scrubber.  `crate::dynamic::rand::SpecRng` is seeded from each `HarnessSpec`'s hash and audited by `scripts/check_no_unseeded_rand.sh`.  `VerifyTrace` (Phase 30) carries every per-step decision into the repro bundle for offline triage.
+- **Headline gate.** `scripts/m7_ship_gate.sh` runs five gates against `tests/eval_corpus/budget.toml` (Phase 31 headline targets: Unsupported < 20% per `(cap, lang)` cell, False-Confirmed < 2% per cap, repro stability ≥ 95%, wall-clock ≤ 2× static-only, sandbox-escape suite green).  `tests/eval_corpus/run_full.sh` is the canonical orchestrator and writes a stable `tests/eval_corpus/results.json` for the gate + the published metrics table in `docs/dynamic.md`.
+
+The default-on flip is gated on `m7_ship_gate.sh` exit 0 against the eval corpus.  Engine follow-ups blocking the gate are tracked in `.pitboss/play/deferred.md` (per-language probe-shim splicing for Go / PHP / Ruby / Rust / C / C++, composite chain reverifier live execution path, telemetry repro-stability stamping, and image-builder catalogue digest population).
+
 ## [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.

+## Headline metrics
+
+The dynamic-verification overhaul ships with four published acceptance targets,
+gated end-to-end by `scripts/m7_ship_gate.sh` (Phase 31) against the eval
+corpus (OWASP Benchmark v1.2 + NIST SARD subset + the in-house curated set
+from `tests/benchmark/corpus`):
+
+| Metric | Target | Gate | Source |
+| --- | --- | --- | --- |
+| Unsupported% per `(cap, lang)` cell | < 20% | M7 Gate 1 | `tests/eval_corpus/budget.toml` → `[default].unsupported_rate` |
+| False-Confirmed% per cap | < 2% | M7 Gate 2 | `~/.cache/nyx/dynamic/events.jsonl` (`kind: feedback`, `wrong: true`) |
+| Repro stability | ≥ 95% | M7 Gate 5 | `~/.cache/nyx/dynamic/repro/*/reproduce.sh` exit 0 |
+| Wall-clock cost | ≤ 2× static-only | M7 Gate 3 | `benches/fixtures/` (default vs `--no-verify`) |
+
+The corresponding orchestrator is `tests/eval_corpus/run_full.sh`; it bundles
+the three corpus sets, writes a canonical `tests/eval_corpus/results.json`,
+and propagates the per-cell budget through `tabulate.py` and `report.py`.
+
+A non-zero exit from `m7_ship_gate.sh` is a hard merge blocker for the
+default-on flip.  Failures map back to the engine follow-ups recorded in
+`.pitboss/play/deferred.md` (per-language probe-shim splicing, composite
+chain reverifier wiring, telemetry-stability stamping, et al.).

 #
-# Phase 29 (Track I): replaces the single global Unsupported-rate gate in
-# tests/eval_corpus/report.py with per-cell targets. Each cell records the
-# largest tolerated rate today plus a deadline date for the next ratchet.
+# These are the published acceptance numbers behind the dynamic-verification
+# overhaul (see `docs/dynamic.md` "Headline metrics").  The ratchet schedule
+# from Phase 29 collapsed into a single target row: every (cap, lang) cell is
+# now gated against the same headline thresholds.  Per-cell carve-outs were
+# dropped in Phase 31; if a cell is still wider than these numbers in practice
+# it shows up as a per-cell `FAIL` in `report.py` and as a gate-1 failure in
+# `scripts/m7_ship_gate.sh`, which is the intended forcing function for the
+# remaining engine follow-ups tracked in `.pitboss/play/deferred.md`.
+#
+# Wall-clock cost (≤ 2× static-only) is enforced separately by Gate 3 of
+# `scripts/m7_ship_gate.sh` against `benches/fixtures/`; it is not a per-cell
