The 13-target benchmark left 3 misses. Root-caused and fixed the two that were
coverage gaps (the third was single-run variance, already handled by the
session-limit fix):
- CRLF header injection (web_crlf_header_go): the agent confirmed the open
redirect on /go?url= and stopped; the CRLF payload was never generated. The
open_redirect skill now tests %0d%0a header injection on the SAME param, and
CHAIN_DOCTRINE says a param landing in a Location header must also be tested
for response splitting. chain.rs: CWE-113/93/644 now provide capabilities;
attack_graph maps their kill-chain stage.
- Second-order SQLi (web_sqli_second_order): the sink was behind /admin, which
the customer account could not reach. CHAIN_DOCTRINE now teaches the
precondition pattern (store the payload, trigger from every identity, escalate
first if the trigger page needs a role you lack, else report as a chained
lead). chain.rs: CWE-564 requires PrivilegedContext so it chains after privesc.
BENCHMARK.md: added the TypeSafe calibrated-adjudication row; dropped the
"genuinely ahead" prose (the table is the summary); condensed the rest
188 -> 89 lines; refreshed scale (27 validators, 47 modules, 383 tests).

Written against what disclosed bug-bounty reports and public write-ups actually
turn up, and chosen by diffing the existing 245 skills rather than restating
them. Each one is built around the same discipline the harness now enforces:
the client-side discovery is a lead, and the finding is what the SERVER did.
Browser instrumentation and client trust:
- browser_runtime_hooking — hook fetch/XHR/postMessage/storage/WebCrypto at
document_start to find what the client is trusted to decide, then prove the
server accepts the tampered value with an independent read-back.
- prototype_pollution_gadget_hunt — pollution is a precondition, not a finding.
Hunt the gadget with a getter on Object.prototype that breaks into the
debugger, quote it as file:line from the bundle, and prove the end effect.
- js_source_deep_analysis — recover original sources from source maps, extract
the API surface the UI never shows, and pair every client-side discovery with
the server request that confirms or refutes it.
- client_side_path_traversal — the evidence is which URL left the browser, and
it is Low until chained to something otherwise unreachable.
Authentication:
- webauthn_passkey_downgrade — passkeys as a system: the usual finding is a
weaker factor nobody removed, or enrollment needing only a session.
- email_verification_bypass — the gate is normally on the login screen, not the
API; address normalisation is where pre-account-takeover lives.
- jwt_jku_x5u_injection — whether the token gets to choose its own verifier.
Server-side reach and money:
- ssrf_render_pipeline — PDF/screenshot/unfurl renderers browse on the server's
behalf, usually with no egress restrictions and often with JS enabled; the
returned document is the exfiltration channel.
- payment_webhook_forgery — prove the ORDER changed state, not that the
endpoint returned 200; idempotency failures are their own finding.
- presigned_url_abuse — the bug is what the API is willing to SIGN, which is an
IDOR with a cloud signature on top.

- New agent account_registration_and_forms (+1 → 430): analyzes the app's forms
and self-registers a benign test account (curl or Playwright) to reach the
authenticated surface when no creds are given.
- Probe extracts form details (action/method/fields/kind/CSRF) so form analysis is
grounded; shown in the probe summary and recon JSON.
- Hard anti-flood guardrail in SAFETY_DOCTRINE + the agent: at most 2 accounts per
engagement, never loop/script/batch the register endpoint or flood the DB; reuse
the account made; a test needing many sign-ups is a lead, not mass-creation.
- Credential vault: engagement_ops directive tells agents to append created
accounts to <run-dir>/vault.jsonl; finish() consolidates to vault.json, masks
secrets in the report, and adds a 'Test accounts created (DELETE after)' cleanup
finding listing each account and how it was created.
- Finding tagging: new auth_context (authenticated/unauthenticated) and account
fields, rendered per-finding in the HTML report.
- Opt-in disposable email (off by default): /tempmail on + RunConfig.temp_email;
agents may use the free mail.tm API to read a registration confirmation code.
- Tests: parse_forms unit tests; docs updated (README/TUTORIAL/RELEASE), counts 430.
- DECISION_DOCTRINE injected into exploit/grey/chain prompts: analyse responses to
pick the technique; map & connect routes (endpoint output → next endpoint input);
hunt sensitive flows; mine parameters (incl. hidden from JS/source maps) and test
per-param; mock realistic (non-PII) data to reach deeper logic; exploit the
authenticated surface after login and compare roles; build PoCs when a proof
needs an artifact; bypass 401/403/redirect controls.
- REPL /auth now supports multiple named identities (/auth admin <hdr>, /auth user
<hdr>; bare token → Bearer). With >=2 roles the run gets the access-control
directive (IDOR/BOLA/BFLA/privesc, authorized-vs-unauthorized) and tests both.
- +6 decision agents (library 389): param_miner, endpoint_flow_linker,
authenticated_surface_exploit, clickjacking_poc (HTML PoC), csrf_poc (HTML PoC),
access_control_bypass.
- Docs: counts 383->389, RELEASE + /auth help updated.
- tool_doctrine: agents now actively DRIVE the browser on JS/SPA targets — use
the Playwright MCP (render, read live DOM, click client-side routes, watch the
network to find the real API, screenshot proof); when no MCP, use the Playwright
CLI (write+run a small script / npx playwright screenshot) to render and capture
XHR/fetch traffic — complementing curl (which only sees the empty shell).
- probe: detect SPAs (<app-root>, ng-version, near-empty body + linked scripts →
Angular/React/Vue/SPA) and note in recon that the browser is required, so the
SPA agents get selected.
- +8 SPA/API agents (library 383): spa_api_discovery, spa_hidden_admin,
login_sqli_bypass, dom_xss_spa, api_bola_numeric_ids,
register_privilege_mass_assign, jwt_forgery_spa, spa_business_logic.
- Docs: README/RELEASE/TUTORIAL counts + notes.
