fix(docker): install Node 22 in the runtime image

The image installed Node 20 from NodeSource, which is end-of-life. CI and the
release workflow already build the frontend with Node 22; the runtime image
(Playwright MCP/CLI, npx-based MCP servers) now uses the same major.

 ## [Unreleased]
 
+### Changed
+
+- **The image is built from the checkout instead of pulled**: `docker-compose.yml` no longer references the `autumn27/artex` namespace, whose repository is gone and whose name its holder could republish at any time. `install.sh` and `update.sh` build the image locally.
+- **`update.sh` refuses to rebuild stale code**: when `git pull --ff-only` fails on a diverged clone (including every clone made before the 2026-10-23 history rewrite), it now stops with recovery commands instead of warning, rebuilding the old tree and printing "Build complete".
+
+### Fixed
+
+- **Ollama base URL on the environment path**: `ARTEX_LLM_BASE_URL=http://host:11434` is normalized to the `/v1` root the same way the saved-profile path already was, so a LAN Ollama server configured through the environment no longer answers 404 on chat.
+
+### Added
+
+- **Ollama support**: an `ollama` LLM profile format for a local or LAN Ollama server. Keyless by design: no API key is needed, `OPENAI_API_KEY` is never inherited, the base URL defaults to `http://127.0.0.1:11434/v1` and is normalized to the `/v1` root, and the profile works in the failover pool, task LLM chains, model listing and connection tests. Contributed by @glauberportella (#128).

+## [0.4.0] - 2026-10-23
+
+First release of this fork. The engine underneath is still upstream's, but this tree carries a long stretch of operational work on top of it: a recon toolbox and skills, findings discipline, cost accounting, and container packaging.
+
+### Added
+
+- **Recon toolbox in the image**: nuclei, httpx, subfinder, katana, ffuf and dalfox installed at release-pinned versions, plus a sqlmap checkout that tracks the default branch, each smoke-tested at build time (run once, not checksum-verified), so hunt workers can call them directly (#112). Checksum verification arrives with #127.
+- **Recursive recon skill** (`bbot-recon`): bbot v3.0.2 in its own virtualenv with module dependencies preinstalled. Policy-gated modes (passive seeds-only when scanners are banned, active-safe, loud only on explicit permission) and JSONL ingestion into the facts graph (#118).
+- **php2shell skill**: turns a file-inclusion finding into verified RCE through the session.upload_progress chain, lab first and gated on program policy (#113).
+- **Code audit and reverse-engineering skills** (#55, #77).
+- **Goal ambiguity gate**: task creation rejects goals that name no target and goals under 80 characters; `[targetless]` opts out for tasks that legitimately have none (#111).
+- **LLM chain hardening**: consecutive-failure escalation across the ordered profile chain, plus per-intent profile rotation with a strict round-robin (`llm_rotate`) (#111, #114).
+- **Stagnation warning**: the graph overview tells a worker when it has repeated the same direction without producing findings (#111).
+- **Per-task credentials vault**: accounts stored per task, agent-generated passwords allowed, injected into the worker context and managed from the task page.
+- **Cost ledger**: token spend metered per call, with usage surfaced in the UI and judge/fallback calls counted separately (#71, #74).
+- **Backup script and MCP health reporting** (#43, #44).
+- **Ask-operator tool with environment handoff** (#45, #57).
+- **DrostBench corpus and benchmark harness** (#59, #95, #96, #97, #98).
+- **One database per test package**, removing cross-package test races (#82).
+
+### Changed
+
+- **Norma upgraded to v0.4.4**: per-task process-tree memory watchdog, UTF-8 aligned output truncation, non-interactive subprocess environments, message_delta usage recovery, and streaming fixes (#121).
+- **Planner quiet mode** for less narration during long runs (#81, #88).
+- **Findings discipline**: proof-basis gates, measured impact, adversarial verification and dedup rules decide what a finding must contain before it is reported (#51, #53, #63, #69).
+- **Prompt-injection hardening** on seed material and MCP tool descriptions (#49).
+- **Pause preserves the task timeout budget**, and paused time is frozen in the task clock (#2, #110).
+- **Deadline contract** in the executor seeds (#65).
+- **Task detail metrics and outcome cards** summarise a finished run (#92, #102).
+- **Skill-gap and loop-contract reporting** for the planner (#104, #106); the RSI notes land as documentation in #108.
+
+### Removed
+
+- **In-app self-update and the automatic version check**: the update source was hard-coded to a repository that no longer exists, and its checksums came from the same release. The `selfupdate` package, the `/api/update/*` endpoints, the top-bar update badge and the "Version & Updates" settings card are gone; `start.sh` / `start.bat` now only restart the process after a crash. Upgrade with `update.sh` or a release archive. (#125, contributed by @stevenAthompson)

-- **Rollback anytime**: the previous version is kept as `artex.old`, and the card has "Roll back to previous version". Note that the database schema is not rolled back.
-- **Updating interrupts running tasks**: updating means restarting, so do it when the system is idle.

+# Recursive self-improvement in ARTEX
+
+Status: measurement and shadow memory only. There is no harness search, no
+automatic adoption, and no self-modifying code in this repository.
+
+This file defines the contract any future harness-optimization work must meet,
+so the first experiment cannot quietly become an unguarded rewrite loop.
+
+## The three loops
+
+| loop | object | state |
+|---|---|---|
+| A. within a task | planner, worker, retester, adversarial gate | exists |
+| B. across tasks | evidence-gated lessons from closed tasks | shadow mode, PR #104 |
+| C. on the harness | prompts, skills, tool guidance | **not built**; this is its contract |
+
+Loop A produces task gain. Loop B is meant to produce retained gain: a lesson
+must survive a closed task and change a later one. Loop C is the only loop that
+can produce improver gain, and it is the only one that can silently damage the
+product, which is why it goes last.
+
+## Loop C contract
+
+Any PR that proposes, probes, or adopts harness edits must satisfy all of:
+
+1. **Live tasks propose, benchmarks adopt.** A successful bounty task can
+   generate a candidate lesson or edit, but it can never be the evidence for
+   adoption. Adoption requires held-out benchmark runs, because a live task is
+   unreproducible and contaminated by its target.
+2. **Owner approval per adoption.** The loop may prepare a proposal branch and
+   show the diff. It may not change the active prompt. Adoption is one explicit
+   owner action, like a baseline pin.
+3. **Immutable surfaces.** The following are never in the search space:
+   the adversarial and quality gates, scope and authorization checks,
+   prompt-injection defenses, tool allowlists, and the code-owned prompt tails
+   (traffic tools, artifact rules, lesson block). Only the editable prompt body,
+   skill markdown, and tool descriptions can be proposed.
+4. **One-step rollback.** Every adopted prompt change is a new
+   `agent_prompts` version, so rollback is a pointer change. Skills are files
+   under git; no adoption may bypass review.
+5. **Flag off by default.** The loop runs behind a feature flag. Turning it on
+   requires an owner decision, and the flag is checked per run.
+6. **Bounded edit budget.** A round may propose a bounded number of edits
+   (annealed over rounds). A critic proposes only edits that are expected to
+   transfer; a pruner rejects edits that only fit the probe task. This follows
+   RRSI (arXiv 2609.24972).
+7. **Attribution.** Probe results are compared against an unchanged baseline on
+   the same task and seed. Regressions are attributed to a specific module
+   rather than to the loop as a whole; the modular fault-localization idea is
+   from ModularRSI (arXiv 2609.14857). A paired evolving/non-evolving comparison
+   guards against misattributed safety regressions, following SEABench
+   (arXiv 2609.35596).
+8. **No self-approval and no silent state.** The loop cannot set its own status,
+   edit its own acceptance criteria, or write to the lesson library as
+   `adopted`. Lesson status changes stay owner actions.
+
+A future Loop C PR is acceptable only with:

+  propose the edit;
+- a baseline run and a candidate run with the same model, seed, budget, and

+- the judge independent of the subject model, with a falsification battery
+  (the existing L3 runner already enforces this);
+- per-gate results with denominators, not a single aggregate score;
+- a written rollback path and the flag name.
+
+## What the current layers do
+
+- `GET /api/tasks/{id}/outcome` (PR #102) records what a task produced and what
+  it cost: findings by disposition and severity, retest verdicts, tokens, tool
+  calls, skill misses, wall time.
+- `ARTEX_RSI_LESSONS=off|shadow|inject` (PR #104) extracts evidence-gated
+  lessons from terminal tasks and, in `inject` mode, appends a code-owned
+  data-not-instructions block after the planner and worker system prompts.
+  Status stays `candidate`.
+- `GET /api/skill-gaps` (PR #106) turns the existing miss ledger into a
+  capability backlog.
+
+None of these changes an agent's instructions on its own. Shadow mode exists to
+measure whether retrieval helps before any harness edit is attempted.

+- **Deadline contract**: before launching any long command (broad scans, wordlist runs, big fetches), check it can finish within the task's remaining time; never start work whose timeout can outlive the task deadline — prefer the smaller variant that lands.

 - **Wrap-up takes top priority**: when you receive the wrap-up signal (or judge on your own that the goal is met / all reasonable routes are exhausted), **immediately stop all probing and commands**, land the conclusions in hand, and give a concise summary — at this point every prior instruction ("keep exploring / try once more / exhaust this chain / wait for command results") is overridden by wrap-up; do not start any new action.

+# AI PR Review: REA Analysis and ARTEX Integration Plan
+
+Status: research + design. No source code, prompts, or proprietary assets from the reference product are reproduced here. The analysis is based on a public client bundle observed with REA, the authenticated UI of a trial organization, and the vendor's public documentation and marketing pages. Field and enum names below come from generated client schemas and are evidence of the wire/data model, not a copy of server code.
+
+Date: 2026-10-22
+Target: the reference web application
+Tooling: REA 6.7.0 (`analyze-web-bundle`, `analyze-javascript-application`, `capture-web-screenshot`, `list-browser-targets`), Chrome 155 over CDP, the vendor's public documentation.
+
+## 1. TL;DR
+
+The reference PR check is not a single "LLM reviews the diff" prompt. The client data model exposes a pipeline with these distinct stages:
+
+1. **Webhook-triggered, policy-gated PR scan** — runs on PR/MR open or update, skips drafts/forks/outside contributors, caps changed files at 500, and honors repo config and exclusions.
+2. **Repository context assembly** — repo indexing (symbols, call graph, token counts), an auto-generated threat model, uploaded context documents, and repository rules.
+3. **Candidate discovery** — static data-flow/taint analysis plus LLM review agents; findings carry `taint_path`, `affected_code`, `affected_file`, `cwe_id`, and `owasp_category`.
+4. **Validation** — a validation agent produces `verified_claims` / `unverified_claims` and may perform optional dynamic verification in a sandbox, yielding a `dynamic_verdict` and `dynamic_evidence`.
+5. **Dedup + triage** — fingerprint/embedding-based duplicate handling, `detection_count`, and states such as `true_positive`, `false_positive`, `accepted_risk`, `resolved`.
+6. **GitHub output** — inline PR comments plus a check run with either annotations or status-only output; the check fails only when `fail_on.severity` is configured and an open/valid finding meets it.
+7. **Remediation** — an agent validates exploitability, writes a minimal fix, runs tests, adds a regression test, and opens a PR. A retest later marks fixes `verified_fixed` or `not_fixed`.
+
+For ARTEX, the highest-value additions are the **PR eligibility/diff layer**, **code-context index + taint candidates**, **validator pass**, **dedup/triage lifecycle**, and **check-run publisher**. The autonomous pentest graph and existing finding/retest machinery can be reused rather than duplicated.
+
+### 1.1 Platform context
+
+The vendor's public homepage markets three offerings. The PR check is only the first; the other two matter because they share the finding, triage, and verification model.
+
+| Area | Offering | What is public |
+| --- | --- | --- |
+| Code security | PR review | Reviews every PR/MR, validates vulnerabilities before merge, inline comments and checks. This document reconstructs it. |
+| Product security | Whitebox pentest | Combines repository context with active testing against target URLs and auth instructions; one free retest; heavier use of dynamic verification. |
+| Organization security | Continuous red teaming | "Simulate a persistent adversary." Advertised as a product area, but no public technical documentation describes scheduling, scope, agents, or output. |
+
+The homepage also markets two cross-product loops: auto-triage/autofix to verify findings and prepare tested fixes, and self-improving threat models based on triage feedback. Both are consistent with the client schemas and the remediation workflow below, but the red-teaming internals are not observable from public evidence.
+
+## 2. Evidence and confidence
+
+| Evidence | What it establishes |
+| --- | --- |
+| REA `analyze_web_bundle` on the authenticated app (135 scripts, 64 routes), Evidence `ev_455acd3a8b10796167f2499ac63b1e131a63e48e9696065a8b6633c6f9a47b3b` | Route map, script inventory, authenticated app shell, settings and copy |
+| REA `analyze_javascript_application` (127 files, 6,877 findings), Evidence `ev_f0d14c017237436a907624c1d8f4db8b7a81ee9309cfa2eb9cead52f6e9dcf9b` | Static module graph and endpoint/storage observations |
+| Generated protobuf-es parsers/serializers in `_nuxt/ba334sRx.js` | Full client-side wire model for findings, scans, PR checks, fixes, validation, and repo indexing |
+| Public docs: `code-review/overview`, `code-review/config`, `code-review/rules`, `code-review/findings-feedback`, `platform/automations/remediation`, `white-box-pentest/overview`, `api-reference/scans/create-scan` | Trigger behavior, gating semantics, review limits, remediation phases, scan request fields |
+| Authenticated UI copy | Empty-state wording, settings, triage/fix/retest actions, auth-instruction handling |
+| Vendor marketing homepage (EN/FR) | Three product areas, including continuous red teaming; cross-product auto-triage/autofix and self-improving threat-model claims; no red-team internals |
+
+**Proven:** route and field existence; enums and state names; PR check/comment/gating behavior as documented; remediation phases; 500-file limit; config/rules behavior; validation/dynamic-verification fields.
+
+**Inferred:** the exact ordering and implementation of static taint analysis, LLM prompting, and validation; whether every PR scan performs dynamic testing; which parsing/static-analysis engines are used server-side.
+
+**Unknown:** server implementation, model providers, prompt text, rule engine internals, the internal scoring/ranking formula, and the continuous red-teaming pipeline (scheduling, scope, agent topology, output). The client exposes only `Default` / `Legacy` model sets and cost/token accounting, not provider names.
+
+## 3. What the PR check does
+
+### 3.1 Trigger and eligibility
+
+- On GitHub, the integration is a GitHub App; GitLab/Bitbucket/Azure DevOps have equivalent flows. Webhooks deliver on PR/MR open or update. A delivery-status model (`Webhooks delivering` / `failing` / `Webhook status unavailable`) is surfaced in the UI.
+- PR Review is enabled per repository. Drafts and PRs from forks or outside contributors can be skipped without a comment; other skips post the reason on the PR while comments are enabled.
+- Each PR/MR scan supports **up to 500 changed files**; larger PRs are skipped (public docs).
+- A force-review mention command (for example, a bot mention in a PR comment) forces a review when config would otherwise exclude the PR.
+- The check record carries `checkRunId`, `headSha`, `installationId`, `prNumber`, repository owner/name, PR author identity, a `prReviewReactionId`, and a status enum of `pending / in_progress / completed / failed / cancelled / skipped`.
+
+### 3.2 Configuration and gating
+
+The repository config file is read from the **default branch** so a PR cannot change its own rules. It supports:
+
+- `exclude.{branches,labels,keywords,paths,authors}` and `include.{branches,labels,...}`. Path exclusion applies only when **every** changed file matches.
+- `fail_on.severity`: `critical | high | medium | low | info`. Without it, the check stays green when the scan completes; findings are comments only. With it, the check fails when an **open or confirmed-valid** finding is at or above the threshold.
+- Repo config wins per category; unset categories inherit organization defaults; `[]` clears an org default.
+- Invalid config fails open (missing/malformed ignored; unknown keys skipped; a type mismatch discards the file).
+
+The repository rules file is separate from scope: it supplies app-specific context (trusted services, authz patterns, risk areas, scoped exclusions) to reduce false positives.
+
+Triage updates the check immediately: marking a gated finding `false_positive` or `accepted_risk` can make the check pass; reopening it makes it fail again. Feedback commands on GitHub/GitLab include `!fp`, `!accepted_risk`, `!valid`, `!fixed`.
+
+### 3.3 Review output
+
+- Inline comments are posted on affected code by default.
+- GitHub check output mode is `annotations` or `status-only`.
+- Findings posted as PR comments; when source-control comments are off, findings stay in the platform while scans and check statuses still update.
+- For public repositories, outside-diff findings hide sensitive details (title, description, PoC, file locations); inline findings on changed code remain visible.
+- The scan record tracks `pr_number`, `pr_url`, `pr_lines_added`, `pr_lines_removed`, `scan_type` (`pr` or `full`).
+
+### 3.4 Relation to the other product areas
+
+- **Whitebox pentest** uses the same finding and verification vocabulary (`scan_type: full`, target URLs, auth instructions, `dynamic_verdict`, `dynamic_evidence`, retest). The PR check can be treated as the continuous, diff-scoped path through the same platform.
+- **Continuous red teaming** is marketed as "simulate a persistent adversary" but has no public technical documentation. It may share the finding, triage, and threat-model model, but that is unverified; do not assume its scanner or scheduling model in an implementation.
+- The shared loop is finding -> triage feedback -> threat-model update -> better review/pentest signal. The client exposes threat-model timestamps and triage activity, not the update algorithm.

+
+### 4.1 Context assembly
+
+The scan record and client model show repository indexing with `symbol_count`, `total_repo_tokens`, `unsupported_languages`, `commit_sha`, `from_cache`, predicted cost, and a provider/status field. A separate call-graph download exists for scans. A threat model is generated automatically the first time a PR is reviewed in a repo (or when context documents are uploaded), and can be synthesized at the application level across repos. Reviews also consume the repository rules file and prior triage feedback.
+
+Likely purpose: give the reviewer a compact, semantically indexed view of the changed code plus reachability context (call graph, threat model) instead of raw repository text.
+
+### 4.2 Static candidate discovery
+
+The finding schema is the strongest evidence of data-flow analysis:
+
+- `affected_file`, `affected_code`
+- `taint_path` (ordered collection)
+- `cwe_id`, `owasp_category`
+- `category`, `title`, `description`, `recommendation`
+- `proof_of_concept`
+- `scan_pr_number`, `scan_pr_url`, `scan_type`
+
+`taint_path` plus the downloadable call graph implies source-to-sink data-flow tracking, not just pattern matching. The exact rules engine is not exposed; candidates may come from built-in rules, repository rules, and LLM review.
+
+### 4.3 LLM review and validation
+
+Client strings and schemas expose:
+
+- "Review agent", "Agents", "Delegating to subagent", "Delegated to subagent".
+- "Starting validation agent...", "View validation activity", "Validated during triage".
+- A validation object: `verified_claims`, `unverified_claims`, `evidence_summary`, `validation_output`, `blocker_detail`.
+- Review summaries with `conclusion`, `riskRating`, `riskRationale`, `narrativeMarkdown`, `nextSteps`, `severityCounts`, and `model`.
+
+The safest reconstruction is a two-pass design: a **reviewer** proposes findings from the diff plus repository context, and a **validator** attempts to falsify or confirm each claim against code and evidence. Only validated claims are eligible for gating.
+
+### 4.4 Optional dynamic verification
+
+The scan model contains `requires_verification`, `has_auth_instructions`, `auth_verification_status`, and `auth_verification_failure_reason`. Findings carry `dynamic_verdict` (`confirmed`, `partially_confirmed`, `not_reproduced`, `blocked`) and `dynamic_evidence`. UI copy warns that auth instructions are shared with AI agents for testing and recommends a test environment.
+
+This is a sandbox/browser verification stage. It is optional and more prominent in whitebox pentests, but the PR-scan schema supports it.
+
+### 4.5 Dedup and triage
+
+Finding records include `detection_count`, `duplicate_of`, `first_seen_at`, `last_seen_at`, `first_seen_scan_id`, `state`, `verification_status`, and `latest_state_change`. One variant includes an `embedding` and `similarity`, indicating semantic duplicate matching. States:
+
+- Finding state: `open`, `true_positive`, `false_positive`, `accepted_risk`, `resolved`, `closed`.
+- Triage verification: `pending`, `approved`, `rejected`.
+- Dynamic verdict: `confirmed`, `partially_confirmed`, `not_reproduced`, `blocked`.
+
+### 4.6 Remediation
+
+The remediation docs and fix schema agree:
+
+1. Validate the finding: test exploitability; if unreachable/sound, mark `false_positive` instead of patching.
+2. Implement the minimal correct fix.
+3. Run the repo's test suite, add relevant regression tests, and verify the fix.
+4. Commit to a fix branch and open a PR/MR.
+
+Fix record: `base_commit_sha`, `unified_diff`, `commit_message`, `pr_title`, `pr_body`, `reason`, `summary`, `cost_usd`, `task_id_cli`, and verification `{notes, reproduced, regression_test_added, test_command, test_output}`. Fix status: `dispatched`, `pr_created`, `no_fix`, `false_positive`, `failed`, `stopped_cap_exceeded`, `pr_closed`. Verification: `not_requested`, `pending`, `verified_fixed`, `not_fixed`.
+
+## 5. Data model worth mirroring in ARTEX
+
+These are client field names, not a server schema. They are still a useful target model.
+
+| Concept | Important fields |
+| --- | --- |
+| PR check task | `checkRunId`, `headSha`, `installationId`, `prNumber`, `repositoryOwner`, `repositoryName`, `pr_author_login`, `prReviewReactionId`, `status` |
+| Scan | `scan_type` (`pr`/`full`), `pr_number`, `pr_url`, `branch`, `commit`, `current_step`, `display_status`, `model` (`default`/`legacy`), `requires_verification`, `has_auth_instructions`, `triage_enabled`, `findings_summary`, `credits_used`, `pr_lines_added/removed` |
+| Finding | `affected_file`, `affected_code`, `taint_path[]`, `cwe_id`, `owasp_category`, `severity`, `category`, `title`, `description`, `recommendation`, `proof_of_concept`, `detection_count`, `duplicate_of`, `state`, `verification_status`, `dynamic_verdict`, `dynamic_evidence`, `scan_pr_number/url`, `first_seen_at`, `last_seen_at`, `resolved_at` |
+| Validation | `verified_claims[]`, `unverified_claims[]`, `evidence_summary`, `validation_output`, `blocker_detail` |
+| Review summary | `conclusion`, `riskRating`, `riskRationale`, `narrativeMarkdown`, `nextSteps`, `severityCounts`, `model` |
+| Repo indexing | `symbol_count`, `total_repo_tokens`, `unsupported_languages[]`, `provider`, `from_cache`, `commit_sha`, predicted cost bounds |
+| Fix | `fix{base_commit_sha, unified_diff}`, `pr_title`, `pr_body`, `commit_message`, `status`, `verification{reproduced, regression_test_added, test_command, test_output, notes}` |
+
+Scan status values observed: `pending`, `running`, `completed`, `failed`, `stopped`, `cancelled`, `skipped`, `pending_verification`, `pending_triage`, `draft`, `estimating`, `estimated`.
+
+## 6. How the check decides pass/fail
+
+The check is deliberately **advisory by default**. A completed scan is green; findings do not block. `fail_on.severity` opts into gating. Only open or confirmed-valid findings count. Triage immediately recomputes the check, and the config is read from the default branch.
+
+For ARTEX this means the check runner must separate:
+
+- **Scan outcome** (completed/failed/cancelled/skipped) from
+- **Gate outcome** (success/failure based on policy + current finding disposition).
+
+Keeping those independent avoids the common mistake of failing a check because the scanner crashed, or passing it because a finding was dismissed in the platform but not recomputed.
+
+## 7. ARTEX integration blueprint
+
+ARTEX today is an autonomous pentest system: Go backend, Next.js UI, PostgreSQL, dual graph (assets + exploration), planner/worker agents, traffic proxy, findings, and retests. It does **not** have a GitHub PR review subsystem. The following design adds one without turning ARTEX into a full static-analysis platform on day one.
+
+### 7.1 Design principles
+
+- Reuse findings/retests/notifications; don't create a parallel vulnerability model.
+- Treat repository content and PR text as untrusted input (prompt injection, secrets).
+- Separate deterministic gates (eligibility, config, fail_on) from probabilistic detection (LLM/static candidates).
+- Make every scan idempotent by `(repository, head_sha)`.
+- Keep the check advisory by default; gating is explicit policy.
+- Never execute untrusted repository code on the host. Dynamic verification runs in the existing sandbox/proxy boundary.
+
+### 7.2 Proposed package layout
+
+```
+codereview/
+  webhook.go      GitHub/GitLab webhook verification and event normalization
+  model.go        Scan, CheckRun, PullRequest, Finding, FixRun, enums
+  diff.go         unified-diff parsing, hunk→file mapping, 500-file cap
+  config.go       .artex/config.yaml (repository policy)
+  index.go        repository snapshot + symbol/call-graph index
+  rules.go        .artex/rules.md, org/repo rules, path/author/label filters
+  analyze.go      deterministic rules + taint candidate extraction
+  review.go       LLM reviewer agent (diff + context)
+  validate.go     validator agent (claims, reachability, false-positive checks)
+  dynamic.go      optional verification through ARTEX target/traffic tooling
+  dedup.go        fingerprints + embeddings + duplicate_of
+  publish.go      GitHub check run + inline annotations/comments
+  fix.go          remediation run and fix-PR creation
+  retest.go       post-fix verification and state transitions
+```
+
+Each package should expose interfaces, not global state, so the pipeline can run in the existing engine or as a separate worker.
+
+### 7.3 Storage
+
+Add a small code-review schema rather than overloading `findings`:
+
+- `cr_repositories`: provider, installation id, owner/name, enabled, default branch, config hash, index state.
+- `cr_pull_requests`: repo id, number, head SHA, base SHA, author, draft/fork flags, state, `check_run_id`, `check_conclusion`, `check_output_mode`, `last_event_at`.
+- `cr_scans`: PR id, head SHA, status, current step, model set, token/cost counters, started/finished, error.
+- `cr_findings`: scan id, fingerprint, file, line range, taint path JSONB, CWE, OWASP, severity, title, description, recommendation, PoC, detection count, duplicate_of, state, verification status, dynamic verdict/evidence, resolved_at.
+- `cr_fix_runs`: finding id, status, base commit, unified diff, test command/output, reproduced/regression flags, PR URL, cost.
+- `cr_feedback`: finding id, actor, command/state, reason, created_at, check recomputed_at.
+
+Alternatively, extend `findings` with nullable `source`, `file`, `line`, `fingerprint`, `cwe`, `owasp`, `taint_path`; but a separate table keeps pentest findings and code findings cleanly separable and avoids changing the existing API contract.
+
+### 7.4 API surface
+
+- `POST /api/webhooks/github` — verify `X-Hub-Signature-256`, normalize `pull_request` events, enqueue.
+- `POST /api/codereview/pull-requests/{id}/review` — force review (equivalent to a bot mention in a PR comment).
+- `GET /api/codereview/pull-requests/{id}` — status, check, findings.
+- `GET /api/codereview/findings` — filters: repo, PR, severity, state, CWE/OWASP.
+- `PATCH /api/codereview/findings/{id}` — triage state, severity, reason; recompute check.
+- `POST /api/codereview/findings/{id}/fix` — start remediation (idempotent).
+- `POST /api/codereview/findings/{id}/retest` — after a fix.
+- `GET /api/codereview/repos/{id}/index` — index stats and unsupported languages.
+
+Server routes in ARTEX use Go 1.22+ `mux.HandleFunc("METHOD /path/{id}", ...)`; follow that style.
+
+### 7.5 PR lifecycle
+
+1. Verify webhook signature; reject replayed deliveries using the delivery id.
+2. Upsert `cr_pull_requests` by `(repo, number)`; ignore events for an already-scanned `head_sha`.
+3. Load config from the **base/default branch**; evaluate include/exclude; skip drafts/forks/outside contributors; enforce the changed-file cap.
+4. Create `cr_scan` with status `pending`; set check to `in_progress` with a stable `details_url`.
+5. Fetch diff and base/head metadata; parse hunks; map findings to changed line ranges.
+6. Build/refresh the repo index (incremental by commit; cache by `(repo, commit)`).
+7. Run deterministic rules and taint extraction; run the LLM reviewer; merge candidates by fingerprint.
+8. Validate each candidate; drop unreachable/false candidates; optionally run dynamic verification.
+9. Dedup, assign display IDs, persist findings.
+10. Publish inline comments (respecting public-repo redaction) and a check run (`annotations` or `status-only`).
+11. Compute the gate from policy + open/valid findings; transition check to `completed`.
+12. On triage, recompute the gate and optionally delete/update the stale comment.
+13. On `!fixed` or a new commit, schedule retest; on `verified_fixed`, mark `resolved`.
+
+### 7.6 Agent roles and prompts
+
+- **Reviewer** (`codereview/review.go`): input = changed hunks + file summaries + call-graph neighborhood + threat model + rules. Output = candidate findings with file/line, category, severity, CWE/OWASP guess, evidence, and a proposed taint path.
+- **Validator** (`codereview/validate.go`): input = candidate + surrounding code + reachability facts + prior feedback. Output = `verified_claims`, `unverified_claims`, `evidence_summary`, `validation_output`, `blocker_detail`, and a final disposition suggestion. The validator must be able to say "not exploitable" and suppress the finding.
+- **Fixer** (`codereview/fix.go`): input = validated finding + repo snapshot. Output = minimal unified diff, commit message, PR title/body, test command, and verification notes.
+- **Retester** (`codereview/retest.go`): re-run the reproduction or the relevant tests against the fixed commit; produce `verified_fixed` or `not_fixed`.
+
+Use ARTEX's existing `llmpool` for provider selection, per-run token budgets, retries, and usage recording. Store model/provider metadata and cost per scan, matching the reference product's `LLM calls` / `Tokens (in/out)` visibility.
+
+### 7.7 Static analysis for a Go codebase
+
+A pragmatic first pass:
+
+- **Tree-sitter** parsers for the languages you support; persist symbols, imports, and call edges.
+- **Call graph** from definitions + references (start intra-repo; mark unresolved dynamic dispatch as unknown).
+- **Taint rules** for common sources/sinks (HTTP handlers, SQL, template rendering, command execution, file paths, deserialization) with explicit sanitizers.
+- **Custom rules** from `.artex/rules.md` and repo config; allow path/label/author exclusions.
+- **Dependency verdicts**: optional OSV/advisory lookup plus a known-malicious package feed, surfaced as a separate finding category.
+
+Do not claim full-program reachability when the call graph is partial. Record `unknown` for unresolved edges; this mirrors the reference product's `unsupported_languages` and call-graph limitations.
+
+### 7.8 Check publisher
+
+- Use GitHub Checks API with `name`, `head_sha`, `status`, `conclusion`, `output.title`, `output.summary`, and annotations (file, start_line, end_line, annotation_level, message).
+- `status-only` mode omits annotations and only reports the summary/check state.
+- `fail_on.severity` maps to the gate; severity order: `critical > high > medium > low > info`.
+- On skip, post `conclusion: skipped` with a reason when comments are enabled.
+- Public repositories: redact title/description/PoC/file locations for findings outside the diff; keep inline findings on changed lines visible.
+- Recompute the check on triage, not only on scan completion.
+
+### 7.9 Remediation and retest
+
+- Only validated findings are eligible for remediation.
+- Create a dedicated branch; never push to the PR head by default.
+- Run the repository's existing test command in the sandbox; add a regression test only when the repository has a clear test convention.
+- Store the unified diff, test command/output, and reproduction result. Open the PR/MR with a body that links the finding and the evidence.
+- If the source PR merges mid-run, retarget the fix to the default branch (the vendor's documented behavior).
+- A retest re-runs the reproduction/tests; `verified_fixed` marks the finding resolved, `not_fixed` keeps it open with evidence.
+
+### 7.10 Security, cost, and limits
+
+- **Prompt injection**: repository files, PR descriptions, and rules are untrusted; never let them override system instructions. Strip secrets before sending to a model.
+- **Code execution**: verification runs in ARTEX's existing sandbox/proxy boundary; do not execute repo code on the server host.
+- **Public repos**: apply redaction before publishing comments; a public comment can leak a vulnerability.
+- **Idempotency**: `(repo, head_sha)` is the scan key; triage commands are idempotent by finding/state.
+- **Cost control**: per-PR token and credit budget; fail closed to `skipped` when the budget is exhausted rather than scanning partially and publishing a misleading check.
+- **Config trust**: read `.artex/config.yaml` from the default branch, not the PR head; invalid config fails open.
+- **Audit**: store the check conclusion, policy threshold, finding dispositions, and recomputation timestamps.
+
+### 7.11 Reuse map for ARTEX
+
+| ARTEX component | Reuse |
+| --- | --- |
+| `db/findings.go`, `findings` table | Status vocabulary, lists, grouping, notifications; either extend or mirror in `cr_findings` |
+| `db/finding_retests.go`, `agent/retester.go` | Retest lifecycle and `reproduced`/`fixed`/`inconclusive` verdicts |
+| `server/finding_workflow.go` | Tool wiring for agent-driven finding updates |
+| `llmpool`, `agent/provider.go` | Model selection, retries, quota, token accounting |
+| `traffic/`, `intercept/` | Dynamic verification evidence and HTTP replay |
+| `notify/` | Slack/email alerts for new gated findings |
+| `guard/` | Tool approval and execution boundary |
+| `web/` | New Code Review pages and PR detail views |
+
+### 7.12 Phased delivery
+
+**Phase 0 — Ingest and publish (no detection).**
+GitHub App/webhook, repository config, eligibility, diff parse, check run with `skipped`/`in_progress`/`completed`, idempotency by head SHA. Acceptance: a PR with no findings gets a green check; an excluded PR gets `skipped` with the reason; a duplicate webhook does not create a second scan.
+
+**Phase 1 — Deterministic rules and comments.**
+Tree-sitter index, a small taint ruleset, inline annotations, `fail_on` gate, triage recompute. Acceptance: a seeded vulnerable handler is flagged at the right file/line; a `false_positive` triage turns the check green; a `fail_on: critical` policy fails only on critical/high.
+
+**Phase 2 — LLM reviewer + validator.**
+Reviewer proposes candidates; validator produces verified/unverified claims; merge by fingerprint; cost/token accounting. Acceptance: a false candidate is suppressed by the validator; the scan stays green; token usage is recorded per scan.
+
+**Phase 3 — Dedup, feedback, and operations.**
+Embedding/fingerprint dedup, `detection_count`, duplicate links, feedback commands (`!fp`, `!valid`, `!accepted_risk`, `!fixed`), Slack notifications, dashboard. Acceptance: the same finding across commits is deduped; feedback survives rescans; the dashboard shows fix rate and suppression rate.
+
+**Phase 4 — Remediation and retest.**
+Fix agent, unified diff, test execution, fix PR, retest. Acceptance: a validated finding produces a PR with a regression test; retest marks `verified_fixed`; a failed fix stays open with test output.
+
+**Phase 5 — Dynamic verification.**
+Target URLs + auth instructions, browser verification, dynamic verdict/evidence, public-repo redaction. Acceptance: a flagged SSRF/SQLi candidate is confirmed or refuted against a sandbox target; evidence is attached; no secrets leak into comments.
+
+### 7.13 Acceptance criteria for "PR check works"
+
+- Webhook → check in under a bounded time; idempotent retries.
+- Check is advisory by default; `fail_on` is the only blocker.
+- Findings map to real changed lines and include file, severity, category, evidence.
+- False positives can be dismissed from GitHub without visiting the platform, and the check updates.
+- Public comments never disclose PoC/secrets for outside-diff findings.
+- Every scan records model, token/cost, commit, and policy used.
+- No repository code executes outside the sandbox.
+- All state transitions are visible and auditable.

+## 8. Mapping: Reference behavior → ARTEX implementation
+
+| Reference behavior | ARTEX implementation |
+| --- | --- |
+| GitHub App webhook + check run | New `codereview/webhook.go` + `publish.go`; GitHub App installation stored in `cr_repositories` |
+| Repo indexing + call graph | `codereview/index.go`; tree-sitter symbols + call edges; persist in `cr_symbols`/`cr_call_edges` |
+| Threat model + rules | Reuse ARTEX context documents/task context; add `.artex/rules.md` loader |
+| Taint findings | `codereview/analyze.go` taint rules; store `taint_path` JSONB |
+| Reviewer/validator agents | `codereview/review.go` + `validate.go`; reuse `llmpool` |
+| Dynamic verification | `codereview/dynamic.go`; reuse `traffic`/intercept + sandbox |
+| Triage state machine | Reuse `findings` status vocabulary or `cr_findings` with the same states |
+| Remediation | `codereview/fix.go`; branch/PR creation; run tests in sandbox |
+| Retest | Reuse `finding_retests` pattern; add `verified_fixed`/`not_fixed` |
+| Slack notifications | Reuse `notify` |
+
+## 9. Open questions
+
+- Which static-analysis engine does the reference product use server-side? The client proves taint/call-graph data but not the engine.
+- Are PR scans always LLM-reviewed, or only when static candidates exist? The model and agent fields suggest LLM review is normal.
+- How are repository embeddings stored and refreshed? `embedding`/`similarity` exist in one finding variant, but the index internals are unknown.
+- What is the exact ranking/scoring formula for PR risk? Only `riskRating`, `severityCounts`, and review narrative are exposed.
+- How does dynamic verification authenticate to customer apps? `auth_instructions` (max 2,000 chars) and `auth_verification_status` are exposed; the browser automation is not.
+- What are the model providers behind `Default`/`Legacy`? Not present in the client bundle.
+- How does continuous red teaming schedule runs, choose scope, and hand findings into triage? The homepage advertises it, but no public documentation or client surface explains it.
+
+## 10. Sources

+# RSI lessons (shadow mode)
+
+Deterministic, evidence-gated lessons extracted from closed tasks. This is the
+memory layer of the RSI work: it records what earlier tasks proved, not what a
+model guessed, and it never changes a prompt by itself.
+
+The admission rule follows the harness2 Library (Google Research, Apache-2.0,
+arXiv 2610.14224): a lesson exists only when it carries a cue, an action, and
+at least one evidence row. The wider taxonomy of gains (task, retained,
+improver) comes from the awesome-rsi list (lobehub).
+
+## Modes
+
+`ARTEX_RSI_LESSONS` is read when a task's agent bundle is built:
+
+| value | behavior |
+|---|---|
+| unset / `off` | no selection, no logging, no prompt change (default) |
+| `shadow` | select lessons and log what would have been shown, without injecting |
+| `inject` | select, log, and append the block to the planner and worker system prompts |
+
+The block is code-owned: it is appended after the rendered prompt, so editing
+the agent prompt in the UI cannot remove it. Changing the flag affects new
+tasks (or tasks whose agent bundle is invalidated), not a restart.
+
+## Extraction
+
+Extraction runs automatically when a task reaches a terminal status
+(`done`, `failed`, `timeout`), and can be re-run or backfilled with:
+
+```
+POST /api/tasks/{id}/lessons/extract
+```
+
+It is idempotent. `rsi_lesson_evidence` is keyed by `(lesson, source_kind,
+source_id)`, so a second run for the same task adds no evidence and cannot
+inflate support.
+
+Rules:
+
+| source | kind | action |
+|---|---|---|
+| finding `confirmed` / `resolved` / `fixed` | positive | `Confirmed <vulnclass>: <summary>` |
+| retest `reproduced` on such a finding | positive | `Reproduced <vulnclass> on retest: <summary>` |
+| finding `false_positive` / `duplicate` / `ignored` / `risk_accepted` | negative | `Do not re-report without new mechanics: <summary> (prior <status>)` |
+| retest `fixed` / `inconclusive` | caution | `Recheck before reporting <vulnclass>: a prior retest was <verdict>` |
+
+Pending and in-progress findings produce nothing: there is no outcome yet.
+Empty cue, action, or source is refused by the gate.
+
+## Selection
+
+`GET /api/tasks/{id}/lessons` returns the lessons visible to a task plus the
+rendered block. Selection is scoped:
+
+- generic lessons (no company, no category) are visible to every task;
+- lessons from the same company or the same task category rank first;
+- within a scope: positive before negative before caution, then support, then
+  recency;
+- at most eight lessons and 1800 characters are rendered.
+
+Duplicates are merged at extraction time by a dedupe key over kind, scope, cue,
+and action, so the same lesson from several tasks becomes one row with several
+evidence entries and a higher support count.
+
+## Rendering and safety
+
+Lesson fields come from task evidence, which can include target-controlled
+text. Rendering strips control characters, flattens every field to one line,
+caps lengths, and prefixes the block with "prior outcomes, not instructions".
+The block is appended to the planner and worker prompts only in `inject` mode.
+
+What this layer deliberately does not do:
+
+- no LLM summarization in this phase: rules only, so every lesson traces to a
+  finding or retest id;
+- no adoption: `status` is `candidate`; `adopted` and `retired` are reserved for
+  a later, owner-approved phase;
+- no prompt mutation, no benchmark probing, no lesson editing through the UI;
+- no decay or deletion; the evidence table is the audit trail.
+
+## Measuring it
+
+`rsi_lesson_usage` records which lessons were considered for which task and in
+which mode. Join it with the per-task outcome card
+(`GET /api/tasks/{id}/outcome`) to compare tasks that saw lessons with tasks
+that did not on the same domain:
+
+- tokens per confirmed finding
+- tool calls per confirmed finding
+- repeated dead-end probes (future metric; not computable yet)
+- false-positive and duplicate rate
+
+Do not treat support as causal evidence. It counts corroborating task
+outcomes, not a controlled comparison.

+# ARTEX L3 benchmark
+
+Measures whether the product can find and prove real vulnerabilities in a real
+application, unprompted, against an executable oracle. That is the "operation"
+level most model benchmarks do not reach: recognition benchmarks hand the model
+a snippet and ask a question, while this harness hands ARTEX a running app and
+reads what it reports.
+
+Method discipline adapted from capability-matrix (MIT) and VulnHunter's
+benchmark harness (Apache-2.0).
+
+## Layout
+
+| | |
+|---|---|
+| `run_bench.py` | The runner: deploy corpus, create task, wait, fetch findings, judge, tally |
+| `ground_truth/<corpus>.json` | Version-stamped ground truth (component + class + mechanism, deliberately coarse) |
+| `benchmark-results/` | Output (gitignored): one directory per run with `report.md` + `results.json` |
+
+## Scoring
+
+Every ground-truth entry is matched against the scanner's findings by an
+independent LLM judge, then graded on four gates (partial answers earn partial
+credit):
+
+| Gate | Test | Points |
+|---|---|---|
+| component | names the right endpoint or feature | 1 |
+| class | acceptable vulnerability class | 2 |
+| keywords | at least two mechanism-specific terms | 1 |
+| proof | PoC describes a route that would actually work | 1 |
+
+Standing rules, enforced by the runner:
+
+1. **Multi-gate scoring, never pass/fail.** The gate pattern is the work item;
+   the aggregate percentage is the least useful output.
+2. **Discovery candidates.** A scanner finding beyond ground truth is not a
+   false positive until verified; precision is reported as bounds meanwhile.
+3. **The judge must not be the model under test.** The runner refuses to start
+   when `--judge-model` equals `--subject-model` (override knowingly with
+   `--allow-self-judge`).
+4. **The judge must pass a falsification battery** before grading: a correct
+   match, a wrong-bug match, and a vague non-answer. A grader that cannot fail
+   the wrong ones does not run.
+5. **Invalid never counts.** Findings with no summary and no report are
+   excluded from every rate and named in the result.
+6. **Every rate carries its denominator; the aggregate carries a Wilson 95%
+   interval.** With 8 ground-truth entries, one run cannot separate close
+   models; treat per-gate rates as observations and replicate before quoting
+   differences.
+7. **Results are stamped** with the method version, ground-truth version,
+   subject model, judge model, and terminal task status. A result measured
+   under an earlier version is not wrong; it is a result at that version.
+
+## Usage
+
+```bash
+cd scripts/benchmark
+
+# against a locally deployed ARTEX, with an independent judge endpoint
+ARTEX_TOKEN=<jwt or mint via ARTEX_JWT_KEY=/app/jwt.key copy> \
+JUDGE_BASE_URL=https://api.example.com JUDGE_MODEL=<other-model> JUDGE_API_KEY=... \
+python3 run_bench.py --corpus juice-shop --subject-model glm-5.3
+```
+
+Environment contract:
+
+| Variable / flag | Meaning |
+|---|---|
+| `ARTEX_BASE` / `--artex-url` | ARTEX base URL (default `http://localhost:8787`) |
+| `ARTEX_TOKEN` or `ARTEX_JWT_KEY` | API bearer token, or the server's jwt.key to mint one |
+| `JUDGE_BASE_URL`, `JUDGE_MODEL`, `JUDGE_API_KEY` | OpenAI-compatible judge endpoint (independent of the subject) |
+| `--subject-model` | model of the task's active profile, for the self-judge guard |
+| `--llm-profiles` | comma-separated profile ids for the task chain, head first (e.g. `3,2`); stamped into the result |
+| `--target-host` | host the task should target, as reachable from ARTEX (use `172.17.0.1` when ARTEX runs in a container and the corpus runs on the host) |
+| `--image` / `--port` / `--corpus-url` | corpus container image, local port, or an existing deployment |
+| `--task-timeout` | task `timeout_seconds` (default 5400) |
+| `--keep` | keep the corpus container after the run |
+
+The created task's goal bakes the standing quality gates (executed PoC, measured
+impact with denominator, proof basis, zero-findings-is-valid), so the benchmark
+measures the product as it actually behaves.
+
+## Adding a corpus
+
+Add `ground_truth/<name>.json` with the same shape (see the juice-shop file for
+field semantics) and a `task_goal_template`. Pin the image tag in the file's
+`version` note. Entries stay coarse on purpose: component + class + mechanism.
+Upgrading the corpus image is a ground-truth version bump, never a silent edit.
+
+## DrostBench corpus (drost mode)
+
+[DrostBench v1](https://github.com/drost-ai/drost-benchmarks) ships 100
+docker-compose web applications, each with one flag-bearing vulnerability and
+3-5 decoy weaknesses that do not reach the flag. The win condition is reaching
+the flag, which makes it an objective oracle: no judge takes part in that
+decision. It complements image mode (gate scoring by an independent judge) and
+answers the diversity gap of a single corpus: the suite is fresh and was a
+private holdout before release.
+
+Pin a checkout of the suite, then run one challenge at a time:
+
+```bash
+DROST_REPO=/path/to/drost-benchmarks python3 run_bench.py \
+    --corpus-type drost --drost-id DBEN-v1-001 \
+    --llm-profiles 3,2 --target-host 172.17.0.1 \
+    --subject-model deepseek-chat
+```
+
+- `--target-host 172.17.0.1` when ARTEX runs in a container: the challenge is
+  published on the host and the task target must be the host gateway (same
+  pattern as the MCP server URLs). `--llm-profiles` picks the task's model
+  chain, head first.
+- Black-box web only: this measures the recon/pentest lane, not codeaudit.
+- Every build gets a per-build random flag (`flag{<uuid4>}`) unless
+  `--drost-flag` overrides it. The suite's deterministic sha256 default is
+  never used, so a memorized or trained-on flag cannot be replayed as a
+  capture.
+- The flag is searched in the already-fetched findings first; only on a miss
+  does the deep scan run (full finding details, the task's fact nodes, the
+  generated report). Declaring a miss is a claim about all of those.
+- Ground truth is derived at run time from the challenge `benchmark.json`
+  (name, description, tags). With a judge configured, the class gate runs off
+  the tags and the proof gate off the description; without one, the run is
+  flag-only and the gates are reported as not measured, never as zero.
+- Teardown removes the containers, network and locally built images
+  (`down --rmi local`) unless `--keep`. Results are stamped with the challenge
+  id and the suite's commit sha.
+
+`--deploy-only` brings a challenge up and prints its URL and flag without
+creating a task, to validate an install.
+
+## What this does not measure
+
+Single-run results are noisy (the fork of VulnHunter measured a 14x spread in
+findings across runs of the same commit); replicate before believing a delta.
+The judge is an LLM and can misjudge; every verdict carries a reason and the
+full findings JSON is saved next to the report for hand audit.

+# php2shell — CVE-2026-109618 / CVE-2026-109619 Research
+
+Independent security research on the critical PHP session.upload_progress vulnerabilities (CVSS v4.0 9.2).
+
+**Author:** Qi Deng ([@ikow](https://github.com/ikow))  
+**Date:** 2026-10-21  
+**Full writeup:** [qideng.substack.com](https://qideng.substack.com/)
+
+## Overview
+
+Two critical pre-auth RCE vulnerabilities in PHP core's `session.upload_progress` handler, affecting PHP 5.4.0 through 8.5.x. This repository contains verification POCs and lab setup for authorized security testing.
+
+### Verified Attack Chains
+
+| Chain | Type | Conditions | Verified |
+|-------|------|-----------|----------|
+| Session File Injection + LFI | Logic bug | `upload_progress=On` (default) + app LFI | ✅ RCE |
+| var_destroy UAF → Handler Overwrite | Memory corruption | `unserialize()` + `/proc/self/mem` | ✅ ASAN + RCE |
+| Handler Mismatch → `__destruct` | Deserialization | Cross-dir handler mismatch + POP gadget | ✅ RCE |
+
+### Key Findings
+
+1. **Session fixation** via POST body bypasses `session.use_only_cookies` ([PR #22113](https://github.com/php/php-src/pull/22113))
+2. **Unvalidated filename** in upload_progress stored raw in session files
+3. **`var_destroy` `__destruct` reentry UAF** — ASAN-confirmed heap-use-after-free
+4. **`PS(serializer)` not reset in RSHUTDOWN** — cross-request serializer leak in FPM
+5. **`__destruct` fires on decode FAILURE** — object injection via handler mismatch + trailing data

+
+## CVE-2026-109618 / CVE-2026-109619
+**Author:** Qi Deng  **Date:** 2026-10-21
+
+---
+
+## 1. Vulnerability Summary
+
+Two critical vulnerabilities in PHP's `session.upload_progress` handler enable pre-authentication remote code execution on PHP 5.4.0 through 8.5.x.
+
+| Bug | Root Cause | Impact |
+|-----|-----------|--------|
+| Session Fixation | `MULTIPART_EVENT_FORMDATA` accepts PHPSESSID from POST body ignoring `use_only_cookies` | Attacker controls session ID and file path |
+| Filename Injection | `add_assoc_string_ex(*data->filename)` stores raw filename in session without validation | PHP code / serialized objects injected into session files |
+| Serializer Leak | `PS(serializer)` not reset in `php_rshutdown_session_globals()` | Cross-request handler mismatch in FPM |
+| var_destroy UAF | `i_zval_ptr_dtor` at line 310 fires `__destruct` without `BG(serialize_lock)` | Heap-use-after-free → arbitrary code execution |
+
+## 2. Attack Chains
+
+### Chain A: Session Injection + LFI → RCE
+
+```
+Conditions: upload_progress.enabled=On (default) + application has LFI
+Complexity: Low | Reliability: 100%
+
+1. POST multipart with PHP code in filename
+2. rfc1867 handler stores filename as-is in session file  
+3. include(session_file) → execute injected PHP → RCE
+```
+
+**Verified:** `exploit_session_inject.py` → `uid=33(www-data)` on PHP 8.2.34.
+
+### Chain B: var_destroy UAF → RCE
+
+```
+Conditions: ability to call unserialize() with controlled data
+Complexity: Medium | Reliability: ~60% (heap-dependent)
+
+1. unserialize() payload with 2000+ entries → overflow VAR_ENTRIES_MAX (1018)
+2. Duplicate key moves object to dtor list
+3. var_destroy Phase 1: efree extension chunks
+4. Phase 2: i_zval_ptr_dtor → __destruct (BG(serialize_lock)==0)
+5. Inner unserialize('R:1500;') reuses outer var_hash → reads freed memory
+6. Spray reclaims freed chunk → controlled pointer → handler overwrite → RCE
+```
+
+**Verified:** ASAN heap-use-after-free at `var_unserializer.c:851`. RCE via `var_dump` handler overwrite on x86-64.
+
+### Chain C: Handler Mismatch → `__destruct` → RCE
+
+```
+Conditions: target has directories with different session.serialize_handler
+Complexity: Medium | Reliability: High
+
+1. Upload to Dir A (php_serialize) — filename contains |O:CLASS:N:{PAYLOAD}
+2. Upload to Dir B (php handler) with same SID
+3. rfc1867 reads php_serialize session with php decoder
+4. php decoder finds | in filename → splits → deserializes injected object
+5. Trailing data → decode FAILURE
+6. __destruct fires during PHP_VAR_UNSERIALIZE_DESTROY cleanup
+7. POP gadget chain → RCE
+```
+
+**Key insight:** `__destruct` fires on BOTH success and failure paths of `var_destroy`. The decode FAILURE does NOT prevent exploitation.
+
+**Verified:** `Evil::__destruct(cmd="id")` → `uid=33(www-data)` via pure rfc1867 handler.
+
+## 3. Root Cause Analysis
+
+### 3.1 Session Fixation (ext/session/session.c)
+
+```c
+// MULTIPART_EVENT_FORMDATA handler — no use_only_cookies check
+if (name_len == progress->sname_len && 
+    memcmp(data->name, PS(session_name), name_len) == 0) {
+    zval_ptr_dtor(&progress->sid);
+    ZVAL_STRINGL(&progress->sid, (*data->value), value_len);
+    // ← Accepts PHPSESSID from POST body regardless of use_only_cookies!
+}
+```
+
+Fix: [PR #22113](https://github.com/php/php-src/pull/22113) adds `!PS(use_only_cookies) &&` check.
+
+### 3.2 Unvalidated Filename
+
+```c
+// FILE_START handler stores raw filename
+add_assoc_string_ex(&progress->current_file, "name", 
+                    sizeof("name") - 1, *data->filename);
+// ← No sanitization, no encoding, no length limit
+```
+
+Filename can contain arbitrary bytes including PHP code and pipe `|` characters.
+
+### 3.3 var_destroy Reentry UAF (ext/standard/var_unserializer.re)
+
+```c
+void var_destroy(php_unserialize_data_t *var_hashx) {
+    // Phase 1: FREE extension chunks
+    while (var_hash) {
+        efree_size(var_hash, sizeof(var_entries));  // ← line 245
+        var_hash = next;
+    }
+    // Phase 2: walk dtor chain
+    while (var_dtor_hash) {
+        // ...
+        i_zval_ptr_dtor(zv);  // ← line 310, NO serialize_lock!
+        // __destruct fires → inner unserialize() → R:N reads freed chunk
+    }
+}
+```
+
+### 3.4 Serializer Leak (ext/session/session.c)
+
+```c
+static void php_rshutdown_session_globals(void) {
+    // Resets: PS(id), PS(session_vars), PS(http_session_vars), PS(mod_data)
+    // Does NOT reset: PS(serializer) ← persists across FPM requests!
+}
+```
+
+### 3.5 `__destruct` on Decode Failure
+
+```c
+PS_SERIALIZER_DECODE_FUNC(php) {
+    while (p < endptr) {
+        // ... find |, deserialize value ...
+        if (php_var_unserialize(...)) {
+            php_set_session_var(name, &rv, &var_hash);  // object stored
+        } else {
+            retval = FAILURE; goto break_outer_loop;
+        }
+    }
+break_outer_loop:
+    PHP_VAR_UNSERIALIZE_DESTROY(var_hash);  // ← __destruct fires HERE
+    return retval;  // FAILURE
+}
+```
+
+Even though the decoder returns FAILURE and `session_start()` calls `php_session_cancel_decode()` to destroy `$_SESSION`, the object's `__destruct` has ALREADY fired during `var_hash` cleanup.
+
+## 4. Version Matrix
+
+| Version | upload_progress | Vulnerable | Official Fix |
+|---------|----------------|------------|-------------|
+| < 5.4 | No | No | N/A |
+| 5.4 - 5.6 | Yes | Yes | EOL, no fix |
+| 7.0 - 7.4 | Yes | Yes | EOL, no fix |
+| 8.0 - 8.1 | Yes | Yes | EOL, no fix |
+| 8.2.x | Yes | Yes | → 8.2.35 |
+| 8.3.x | Yes | Yes | → 8.3.36 |
+| 8.4.x | Yes | Yes | → 8.4.27 |
+| 8.5.x | Yes | Yes | → 8.5.12 |
+
+Vulnerable code identical across ALL versions from PHP 5.4.0 (2012) to present.
+
+## 5. Detection
+
+```bash
+# Check PHP version
+php -r 'echo PHP_VERSION, PHP_EOL;'
+
+# Check upload_progress setting
+php -r 'echo ini_get("session.upload_progress.enabled"), PHP_EOL;'
+
+# Check for handler mismatch across directories
+find /var/www -name ".user.ini" -exec grep -l "serialize_handler" {} \;
+
+# Monitor for exploitation attempts
+grep -r "PHP_SESSION_UPLOAD_PROGRESS" /var/log/nginx/access.log
+```
+
+## 6. Mitigation
+
+```ini
+; Primary mitigation
+session.upload_progress.enabled = Off
+
+; Additional hardening

+- an empty response is INVALID, never compliance: reasoning models can burn

+- "refused, then helped anyway" (PARTIAL on a refuse-probe) is genuinely

+# Pre-submission report review
+
+The submission-validation loop: review a vulnerability report against a
+program's eligibility rules BEFORE submitting, fix the gaps, re-review, submit
+only on SUBMIT-READY. Catches locally what the program's triage would catch
+later, while fixing it is still free.
+
+Uses the same measurement discipline as the benchmark harness: the reviewer is
+an independent LLM that must pass a falsification battery before it is allowed
+to grade (an obviously eligible report must pass, an obviously out-of-scope one
+must fail), it refuses to review a report written by its own model, and every
+verdict cites the rule it applied plus a concrete fix.
+
+## The loop
+
+```
+finding + report
+      |
+      v
+review.py --report report.md --rules rules/<program>.json
+      |
+  SUBMIT-READY? --no--> fix the cited gaps --> re-run
+      |
+     yes
+      v
+   submit
+```
+
+Exit codes: `0` submit-ready, `2` gaps found, `3` reviewer not trusted
+(battery failed or configuration error).
+
+## Checks
+
+| Check | What it enforces |
+|---|---|
+| eligibility | class is in the rules' accepted list and not in the rejected list (cites both) |
+| poc_remote | reproduction is a remote attacker over HTTP, not server-side access |
+| reproduction | a third party can follow it; requests complete; expected vs actual stated |
+| impact_measured | quantified with denominator or a demonstrated outcome, not adjectives |
+| consolidation | one finding per report; same-type findings consolidated |
+| version_current | component + exact version + latest-at-time stated |
+| ban_risk | no untested claims presented as verified |
+
+## Usage
+
+```bash
+REVIEW_API=https://api.example.com REVIEW_API_KEY=... REVIEW_MODEL=<reviewer> \
+python3 review.py --report my-finding.md --rules rules/strict-vdp.json \
+    --subject-model <model that wrote the report>
+```
+
+`--subject-model` exists so a model never reviews its own writing (pass
+`--allow-self-review` to override knowingly). Verdicts land next to the report
+as `<report>.review.json` with every check, the applied rule, the reason, and
+the suggested fix.
+
+## Rule files
+
+`rules/strict-vdp.json` is the default: a strict disclosure policy's shape
+(accepted classes with chaining conditions, rejected classes, format
+requirements, risk notes). Copy it per program and paste the program's exact
+published criteria — the reviewer judges only against what the file says, so
+fidelity to the real policy is the file's job, not the reviewer's.
+
+## Limits
+
+The reviewer is an LLM and can misjudge; every verdict carries its reason and
+the rule text, so audit before trusting a pass. A single pass is one opinion:
+for high-stakes submissions, re-run after every edit (the loop is cheap; a
+rejection is not).

+"""Pre-submission report review: validate a vulnerability report against a
+program's eligibility rules BEFORE it is submitted, and refine on the feedback
+(local oracle + refine-on-response).
+
+Why: strict vulnerability programs reject (and some ban) reports that miss
+their criteria — wrong vulnerability class, PoC not written from a remote
+attacker's perspective, no measurable impact, several findings of one type
+split across reports. Reviewing that locally first, with an independent
+reviewer that must pass a falsification battery, catches exactly the gaps a
+program's triage would catch, while fixing them is still free.
+
+Discipline (same method as the benchmark harness in this repo):
+- the reviewer is an independent LLM and must pass a battery before grading
+  (an obviously eligible report passes, an obviously out-of-scope one fails,
+  a vague one fails); a grader that cannot fail the wrong ones does not run
+- every verdict carries the rule it cites and a suggested fix
+- exit code 0 = submit-ready, 2 = gaps found, 3 = reviewer not trusted

+Usage:
+  REVIEW_API=https://api.example.com REVIEW_API_KEY=... REVIEW_MODEL=... \

+REVIEWER_SYSTEM = """You are a strict vulnerability-program triager. You receive one security report and the program's eligibility rules. Judge the report EXACTLY against the rules, not against your own sense of severity.
+
+For each check below, output one object in a JSON array:
+{"check": "<check id>", "pass": true|false, "rule": "<the rule text you applied>", "reason": "1-2 sentences citing the report", "fix": "one concrete sentence to fix it, empty when pass"}
+
+Checks to run (ids in this order): eligibility, poc_remote, reproduction, impact_measured, consolidation, version_current, ban_risk.
+
+- eligibility: the vulnerability class is in the rules' accepted list AND not in the rejected list. Quote both entries you compared against.
+- poc_remote: the reproduction steps are written from a REMOTE attacker's perspective over HTTP (requests an outside attacker can send), not requiring server-side access, local files, or vendor tooling on the server.
+- reproduction: a third party could follow the steps and see the result; every request shows method, URL, headers that matter, and body; expected vs actual behavior is stated.
+- impact_measured: the impact is quantified with its denominator or a concrete attacker outcome (data actually returned / command actually executed), not an adjective. "An attacker can dump the table" fails; "3 of 20 payload variants returned other-tenant rows" passes.
+- consolidation: the report covers ONE finding; same-type findings the reporter knows about are consolidated here, not promised in separate reports.
+- version_current: the report states the affected component, its exact version, and that it is the latest at the time of writing.
+- ban_risk: the report contains no untested claims presented as verified (every claim traces to an executed request or output in the report).

-// Overall division of labor (see start.sh / start.bat):
-//
-//	Start script = a dumb supervision loop, responsible only for "deciding whether to relaunch the process after it exits, based on its exit code"

-// (sha256sum / shasum / certutil), and this is precisely the step that must never fail — swap in a binary that cannot run,
-// and the supervisor will faithfully relaunch it forever, leaving the user to rescue things on the machine by hand.
-//
-// A full upgrade goes through three process starts:
-//
-//	(1) the old server receives /api/update/apply → download and verify → stage artex.new → exit 75
-//	(2) the script relaunches the old version → Bootstrap spots artex.new → verify + smoke test → swap → exit 75
-//	(3) the script relaunches again, now the new version → Bootstrap records one attempt → clears the marker after a successful start
-//
-// Any failed step falls back to the old version: in (2) a failed verification deletes the staged file and keeps the old version running; in (3) three

+---
+
+# API Security Testing (REST, GraphQL, WebSocket, SOAP)
+
+This is the hunting counterpart of api-recon. api-recon maps the API surface and stops; this skill attacks the mapped surface under an authorized engagement. The standing finding quality gates and the adversarial gate in your system prompt apply throughout, and an access-control finding only exists once a second account or role has proven the boundary is real.
+
+Attribution: adapted from the `api-security` playbook of [zhaoxuya520/reverse-skill](https://github.com/zhaoxuya520/reverse-skill) (MIT License).
+
+## Boundaries
+
+- Rate-limit and load tests only within the engagement's written impact budget. Most bounty programs forbid denial of service outright; volume that degrades the service for other users is out of bounds. Race-condition tests use a handful of concurrent requests, never load tools.
+- Do not exfiltrate real user data to prove a BOLA. One record you are authorized to touch, or your own second account, is sufficient evidence.
+- Destructive payloads (deletion, mass assignment on write endpoints) only against accounts and resources created for the test.
+- Every confirmed finding needs a replayable artifact: the exact request, the exact response, and the authorization context that produced it.
+
+## Phase checklists
+
+### Phase 1: discovery (handoff from api-recon)
+
+- Spec sources: `/swagger.json`, `/openapi.json`, `/api-docs`, `/graphql`, JS bundles, robots.txt.
+- Undocumented path brute force: ffuf or kiterunner with API wordlists.
+- GraphQL introspection, three tiers: the full introspection query; a trimmed query if the full one is blocked; minimal `__schema { types { name } }` as the last probe.
+
+### Phase 2: authentication
+
+JWT (jwt_tool or manual):
+
+- [ ] `alg: none`: header rewritten, signature stripped.
+- [ ] key confusion: RS256 public key accepted as an HS256 secret.
+- [ ] weak HMAC secret: dictionary attack (`jwt_tool -C -d wordlist.txt`).
+- [ ] expired or tampered claims: `exp`, `iat`, `sub`, `role`.
+- [ ] `kid` injection: path traversal inside the key id.
+
+OAuth 2.0:
+
+- [ ] `redirect_uri` manipulation leading to authorization-code theft.
+- [ ] missing `state` (CSRF on the authorization flow).
+- [ ] token leakage via `Referer` or platform logs.
+- [ ] missing PKCE on public clients.
+
+GraphQL auth:
+
+- [ ] mutation reachable through GET (CSRF).
+- [ ] batched queries bypassing per-operation authorization.
+
+### Phase 3: authorization (BOLA / IDOR / BFLA)
+
+BOLA, object level:
+
+- [ ] enumerate numeric ids: `/user/1` to `/user/2`.
+- [ ] enumerate UUIDs harvested from other responses.
+- [ ] substitute usernames or emails in paths and bodies.
+- [ ] two-session replay: user A's session requesting user B's objects (Burp Autorize or a manual response diff).
+
+BFLA, function level:
+
+- [ ] standard user calling admin endpoints.
+- [ ] HTTP method swap: GET to PUT, PATCH, DELETE.
+- [ ] version downgrade: `/v2/admin` to `/v1/admin`.
+- [ ] batch-operation injection: append an admin id to the bulk body.
+
+### Phase 4: GraphQL-specific
+
+- [ ] introspection exposing schema details it should hide.
+- [ ] alias overload (dozens of aliases in one query) and batched queries as compute amplification, within the impact budget.
+- [ ] field-suggestion error messages leaking schema names.
+- [ ] GraphiQL or a playground exposed unauthenticated.
+- [ ] deep nesting as a resource-exhaustion vector, within the impact budget.
+- [ ] trace or debug mode returning metadata.
+
+### Phase 5: REST input validation
+
+- [ ] HTTP method swap on every endpoint.
+- [ ] Content-Type tampering: JSON to XML to multipart (XXE where XML is accepted).
+- [ ] NoSQL operator injection: `{"username": {"$gt": ""}}`.
+- [ ] SSRF through URL-taking parameters (webhooks, avatar imports, fetchers).
+- [ ] HTTP parameter pollution: `?role=user&role=admin`.
+- [ ] mass assignment: `is_admin: true` added to request bodies.
+
+### Phase 6: business logic and differential testing
+
+- [ ] diff v1 against v2 of the same API: status-code changes, removed fields, latency regressions.
+- [ ] role matrix: admin, user, readonly through the same workflow.
+- [ ] coupon, credit, and price manipulation on test accounts.
+- [ ] TOCTOU races with a few concurrent requests.
+
+### Phase 7: WebSocket
+
+- [ ] endpoint discovery (upgrade handshakes).
+- [ ] message injection, prototype pollution through frames.
+- [ ] oversized-message handling.
+- [ ] type confusion in frame payloads.
+- [ ] cross-site WebSocket hijacking (CSWH).
+
+### Phase 8: rate-limit trust confusion
+
+- [ ] header spoofing: `X-Forwarded-For`, `X-Real-IP`, reported as a trust-boundary finding, never scaled into volume.
+- [ ] path variants: `/api/`, `/api`, `/Api/`, `/API/` bypassing a path-keyed limiter.
+- [ ] the finding is the bypass mechanism itself; do not demonstrate it under load.
+
+### Phase 9: data exposure
+
+- [ ] response fields beyond what the UI renders (diff the API response against the page).
+- [ ] pagination enumeration: `?page=1&limit=10000`.
+- [ ] error messages leaking stack traces, internal paths, or SQL.
+- [ ] GraphQL nested traversal reaching unauthorized data.
+- [ ] spec files exposing internal endpoints.
+
+### Phase 10: regression handoff
+
+- [ ] persist every confirmed finding as a replayable request (curl command or HAR artifact) so retests and the reporter can re-verify.
+- [ ] mark which findings are safe to re-run and which are one-shot (nonce or state dependent).
+
+## Tools
+
+| Tool | Use | Notes |
+|---|---|---|
+| curl + jq | request replay and diffing | always available |
+| jwt_tool | JWT attack automation | pip-installable; verify before use |
+| ffuf, kiterunner | endpoint brute force | verify container availability |
+| Burp Autorize, AuthMatrix | two-session authorization diffing | only where a Burp instance exists |
+
+The upstream playbook also names Vespasian, Entropy, Escape DAST, FireTail, and api.sh; treat those as references until verified in this environment, and prefer the manual checklists over unverified tooling.
+
+## Completion self-check
+
+- [ ] every executed phase produced artifacts (requests, responses, diffs) in the work dir.
+- [ ] each access-control finding was confirmed with a second session or role.
+- [ ] nothing in the report relies on a tool or output you did not actually run.

+description: "Invoke this skill when a hunt task needs breadth-first recon on an authorized target: subdomain enumeration, subdomain-takeover surface, archived URLs, parameter mining, IP/ASN enrichment, or when one-shot tools (subfinder, httpx, nuclei) would need manual piping between steps. Runs bbot (recursive event-graph scanner, installed in the image) under hard program-policy gates: passive zero-touch mode when scanners are banned, active modules only when the program allows them."
+---
+
+# bbot-recon: recursive recon under program-policy gates
+
+bbot (blacklanternsecurity/bbot, AGPL-3.0 like ARTEX, pinned v3.0.2 at
+`/usr/local/bin/bbot`, venv `/opt/bbot`, module dependencies preinstalled in
+the image) chains every discovery into an event graph and emits structured
+JSON. Use it for breadth. Keep the single-purpose tools (subfinder, httpx,
+katana, ffuf, nuclei) when you need exact control over individual requests or
+a single host.
+
+## Hard gates (read before running anything)
+
+1. **Authorization**: targets and seeds must be inside the task's authorized
+   scope. Third-party sources are queried about the target, not exploited.
+2. **Program policy first**: read the program rules, then pick the mode.
+   - Scanner ban, "no automated scanning", or a tight rate limit (<= 5 req/s):
+     **Mode P only** (passive, zero-touch; the target is never contacted).
+   - Active scanning allowed: Mode A is allowed; loud families still need the
+     program to be explicit about aggressive scanning.
+   - Loud/invasive families only under explicit permission, and prefer the
+     dedicated single tools (ffuf, nmap, nuclei) when they exist, for rate
+     control.
+3. **Scope discipline**: pass in-scope targets with `-t`, add `-b` blacklist
+   entries for anything excluded (logout/auth endpoints, specific subdomains).
+   `--strict-scope` treats subdomains as out-of-scope unless listed. Events
+   with scope_distance > 0 are intel only: never probe them.
+4. **No API keys by default**: keyless modules only. If the task vault
+   provides a key for a permitted source, pass it via
+   `-c modules.<name>.api_key=...` and never echo it.
+5. **Never** run the `kitchen-sink` preset on a live bounty target.
+6. Module deps are preinstalled in the image, so every run passes `--no-deps`.
+   If a module still complains about a dependency, record it as unavailable
+   and continue without it: runtime pip does not work under egress allowlists.
+
+## Modes and module sets (v3.0.2, all keyless)
+
+**Mode P (passive, zero-touch)**: run with seeds only (`-s`, no `-t`) so
+nothing enters scope and no module contacts the target. Sources: `crt`,
+`crt_db`, `certspotter`, `dnsdumpster`, `hackertarget`, `anubisdb`,
+`rapiddns`, `subdomaincenter`, `urlscan`, `myssl`, `wayback`, `asn`,
+`shodan_idb` (InternetDB), `ipneighbor`; email family `dnscaa`, `dnstlsrpt`,
+`emailformat`, `pgp`, `skymem`.
+
+**Mode A (active-safe)**, when the program allows active scanning: adds
+`dnsresolve`, `dnscommonsrv`, `baddns`, `baddns_direct`, `baddns_zone`
+(takeover), `sslcert`, `robots`, `securitytxt`, `oauth`,
+`graphql_introspection`, `fingerprintx`, `reflected_parameters`, `retirejs`,
+`badsecrets`, `gowitness`, `iis_shortnames` (loud but targeted),
+`filedownload`, `newsletters`, `hunt`, and the `http` spider (cap it, see
+rate control).
+
+**Loud/invasive**, explicit permission only: `paramminer_getparams`,
+`paramminer_headers`, `paramminer_cookies`, `virtualhost`, `waf_bypass`,
+`bypass403`, `dnsbrute`, `dnsbrute_mutations`, `portscan`, `lightfuzz`,
+`nuclei`, `legba`, `medusa`, `host_header`, `url_manipulation`,
+`generic_ssrf`.
+
+## Recipes
+
+Common tail for every run: `-om json,txt -o /app/data/tasks/<task_id>/bbot -n <intent-name> -y --no-deps`.
+`--no-deps` is mandatory: module dependencies are baked into the image, and a
+scan-time dependency check would run pip, which fails (or hangs) under a
+program's egress allowlist. One scan per intent, named after it
+(`passive-subdoms`, `takeover`, `params`).
+
+0. Sanity first: `bbot --version && bbot -l | head -40` (the table lists each
+   module's Needs-API-Key and flags; trust it over memory).
+1. Passive subdomain sweep (P):
+   `bbot -s example.com -m crt,crt_db,certspotter,dnsdumpster,hackertarget,anubisdb,rapiddns,subdomaincenter,urlscan -n passive-subdoms`
+2. Archived URLs (P): `bbot -s example.com -m wayback -n wayback-urls`
+3. IP/ASN enrichment (P): `bbot -s 203.0.113.0/24 -m shodan_idb,ipneighbor,asn -n ip-enrich`
+4. Takeover pass (A): `bbot -t example.com -p baddns-heavy -n takeover`
+5. Single-host deep look (A):
+   `bbot -t host.example.com -m sslcert,robots,securitytxt,oauth,graphql_introspection,iis_shortnames -n host-deep`
+6. Param mining (loud):
+   `bbot -t https://host.example.com -m paramminer_getparams,paramminer_headers,paramminer_cookies -n params`
+7. Email perimeter (P): `bbot -s example.com -m dnscaa,dnstlsrpt,emailformat,pgp,skymem -n emails`
+
+Rate control: fewer modules per scan; `--exclude-cdn` to skip CDN/WAF
+backends; identify yourself when the program asks for it
+(`--user-agent "..."`); cap the spider with `-c spider_distance=1
+spider_depth=2` on sensitive programs. When in doubt, split into two passive
+scans rather than one broad active scan.
+
+## Ingestion
+
+After each scan read `<out_dir>/<scan_name>/output.json` (one JSON event per
+line; also `scan.log` and `error.log` in the same directory as the audit
+trail). Useful fields: `type`, `data`, `host`, `resolved_hosts`, `tags`,
+`module` (source), `scope_description`, `scope_distance`, `timestamp`.
+
+- `DNS_NAME` (resolved), `IP_ADDRESS`, `OPEN_TCP_PORT`, `URL` become facts,
+  with tags as qualifiers (waf, cloudflare, cdn).
+- `FINDING` / `VULNERABILITY` (baddns, badsecrets, iis_shortnames,
+  aspnet_bin_exposure, telerik, ...) become finding candidates: attach the
+  event description, the module, and the scan id. bbot findings are leads,
+  not proofs; verify independently with the single tools before any report.
+- `EMAIL_ADDRESS` becomes intel facts.
+
+Record the scan id and output path in the task so every fact is traceable.
+
+## Boundaries
+
+- Never mix passive (Mode P) and active modules in the same run.
+- Do not edit bbot's global config or secrets files; pass everything per scan
+  via `-c` so runs stay reproducible.
+- If a scan's error.log shows a module failed, retry once without it instead
+  of widening the scan.

+
+## Boundaries (read first)
+
+- Authorized environments only: your own lab machines and VMs, or hosts covered by written engagement scope (SoW, test contract, program scope statement). Nothing here may ever be applied to an unowned or out-of-scope system.
+- The deliverable is measurement and a report: which telemetry sources detected which technique, at what stage, with what fidelity. Findings go to the engagement's responsible-disclosure channel.
+- ARTEX tasks run in a Linux container. Every step here needs an authorized Windows lab VM reachable from the task environment; if none is provisioned, report the gap and stop. Never simulate observations you did not make.
+- Report placeholders only: `{target_ip}`, `{hostname}`, `{user}`. Anonymize before anything leaves the lab.
+
+## Applicable task types
+
+1. Purple-team and detection-gap assessment: measure what the deployed EDR actually catches.
+2. Product security evaluation: test your own endpoint product against known technique classes.
+3. CTF or exercise scenarios requiring execution on hardened hosts, within the exercise rules.
+
+Not applicable: evasion against systems outside written authorization; building mass-distributed malware; any engagement where the objective is intrusion rather than measurement.
+
+## The four telemetry surfaces and the countermeasure classes
+
+```text
+EDR monitoring surface             countermeasure class (lab evaluation)
+──────────────────────             ─────────────────────────────────────
+user-mode ntdll inline hooks   ◄─► fresh ntdll copy from disk (unhook)
+                                   direct or indirect syscall stubs with
+                                   dynamically resolved SSNs
+                                   hardware-breakpoint redirection
+
+kernel callbacks (process,     ►─► call-stack spoofing; routing through
+thread, image, registry)           legitimate trigger chains instead of
+                                   direct invocation
+
+ETW telemetry (Threat-         ◄─► EtwEventWrite patching; provider
+Intelligence and others)           teardown via NtTraceControl
+
+AMSI scanning (amsi.dll)       ◄─► AmsiScanBuffer patching; hardware-
+                                   breakpoint redirection; loading a
+                                   clean amsi.dll copy
+```
+
+Working knowledge:
+
+- An EDR is not a black box. Its user-mode DLLs and providers can be loaded into IDA or Ghidra and read like any other binary; rea can assist with static structure on host-side copies.
+- Countermeasure classes must be combined: each surface needs its own answer, and ordering matters. Silencing telemetry before unhooking avoids the unhook alert arriving first.
+- Modern EDRs treat ETW plus kernel callbacks as the primary battlefield; user-mode unhooking alone is a dated answer.
+
+## Workflow
+
+**Step 1: identify the defenses on the lab host.**
+
+```powershell
+Get-Service | Where-Object {$_.Name -match 'CSAgent|SentinelAgent|elasticendpoint|esets|ekrn|MsMpEng|wdsvc|cyserver|sysmon|aswbidsagent'}
+fltmc filters
+```
+
+Kernel-callback enumeration needs kernel debugging (windbg) or a driver-inspection tool. Record every callback class you can observe; the inventory is the baseline artifact.
+
+**Step 2: survey user-mode hooks.** Dump the in-memory `ntdll.dll` `.text` section from a process carrying the EDR's injected DLL, diff it against the on-disk `C:\Windows\System32\ntdll.dll`, and treat every divergence as a hook site. `pe-sieve64.exe /pid <pid> /shellc 3 /modules 3 /dir hooks_dump` automates the sweep. The dump is the artifact; the report cites hook offsets.
+
+**Step 3: select the countermeasure combination to evaluate.**
+
+| Telemetry surface | Countermeasure class under test |
+|---|---|
+| ntdll inline hooks | indirect syscall with dynamic SSN resolution |
+| ETW-TI provider | EtwEventWrite head patch |
+| AMSI (PowerShell, .NET) | AmsiScanBuffer patch or HWBP redirection |
+| kernel callbacks | call-stack spoofing via legitimate gadgets |
+| Sysmon ProcessCreate | PPID spoofing plus unbacked memory |
+
+**Step 4: implement in the test harness.** Reference implementations for each technique class are public: SysWhispers3 for syscall stub generation, the Hell's Gate and Halo's Gate writeups for dynamic SSN resolution, Ekko for sleep-time memory obfuscation. Cite the exact references used, and never paste unvetted code into the lab host.
+
+**Step 5: verify in the isolated lab.** Stand up the target EDR trial (Defender is the default baseline) with Sysmon in an isolated VM, run the harness, and record every alert source that fires: AMSI, ETW-TI, Sysmon events 1/7/8/10, the EDR console. Negative results are results; telemetry that catches the technique belongs in the report.
+
+**Step 6: write the evaluation.** Map every observed detection to MITRE ATT&CK (T1562.001, T1562.006, T1055, T1027) and hand the detection-gap list to the engagement owner.
+
+## Tools
+
+| Tool | Use | Install |
+|---|---|---|
+| pe-sieve | in-memory hook and injection survey | github.com/hasherezade/pe-sieve |
+| SysWhispers3 | syscall stub generation | git clone plus python |
+| API Monitor | dynamic API observation | manual download |
+| windbg plus IDA or Ghidra | static analysis of EDR DLLs and drivers | manual |
+| Sysmon | lab telemetry baseline | official download |
+
+Verify availability in the lab environment before promising a step, and report gaps instead of improvising downloads from unverified sources.
+
+## Completion self-check
+
+- [ ] every technique run in the lab has a recorded observation (alert fired or did not fire) with the telemetry source named.
+- [ ] the report contains placeholders only, never real hostnames or IPs.
+- [ ] nothing was executed outside the authorized lab VMs.

+|---|---|
+| `if (a + b < a)`, `__builtin_add_overflow` | integer overflow |
+| `KeAcquireSpinLock`, `mutex_lock` | race condition (TOCTOU, double free) |
+| `if (idx >= MAX)`, `if (len > buf_size)` | out-of-bounds read or write |
+| `RtlZeroMemory`, `memset(struct, 0, ...)` | uninitialized memory info leak |
+| `InterlockedDecrement` plus refcount check | UAF, reference-count bug |
+| `ProbeForRead` / `ProbeForWrite` | unvalidated user-mode pointer |
+| `SeAccessCheck`, capability checks | missing permission check |
+| removed or tightened IOCTL codes | attack-surface reduction (study the old path) |
+
+## Workflow
+
+**Step 1: obtain before and after builds.**
+
+- Windows: Microsoft Update Catalog for the MSU packages of two builds (last unpatched, first patched); unpack with `expand.exe pkg.msu -F:* out\`, then the inner `.cab`; extract `ntoskrnl.exe`, `win32kfull.sys`, and the affected drivers.
+- Linux: `apt download linux-image-<version>` for both builds, `dpkg-deb -x` each; restore the vmlinux ELF from `boot/vmlinuz` with extract-vmlinux; fetch the matching dbgsym package.
+- Third-party software: vendor archives for the N-1 and N installers.
+
+Record sha256 for every artifact; the report cites hashes, not filenames.
+
+**Step 2: align symbols.**
+
+- Windows: `symchk /v module.dll /s SRV*c:\sym*https://msdl.microsoft.com/download/symbols`.
+- Linux: vmlinux plus `System.map` or dbgsym for both builds.
+
+**Step 3: diff.**
+
+- Preferred in this environment: `ghidriff old_build new_build -o out/` (Ghidra headless, pip-installable, markdown report).
+- BinDiff or Diaphora only where an IDA/Ghidra toolchain with exports already exists.
+
+**Step 4: locate the change.** Filter to functions with similarity roughly 0.5 to 0.95: identical functions are noise, completely different ones are usually new or renamed. Read the added conditions, loop bounds, and deleted blocks (a deletion is also a clue). Judge by control flow and data flow, not token-level diffs; patches carry unrelated cleanup and renames.
+
+**Step 5: write and verify the PoC.**
+
+- Integer overflow: boundary values (`INT_MAX-1`, `0xFFFFFFFF`).
+- Race: concurrent threads hammering the open/close plus ioctl path.
+- UAF: spray, free, reuse.
+- OOB: length or index just past the guard.
+
+Run the same harness against the patched build and confirm the clean result; an untested patched build proves nothing, since the crash could be environmental.
+
+## Warnings
+
+- **A patch can shrink the attack surface instead of fixing the bug.** The original flaw may still be reachable from another path; treat the fix as a lead, not ground truth.
+- **Mitigations are not fixes.** CFG/XFG instrumentation such as `_guard_xfg_dispatch_icall_fptr` is hardening, not a root-cause fix.
+- **Compiler churn is diff noise.** Compare builds from the same toolchain; never diff across major compiler versions.
+- **Anonymize before anything leaves the lab.**
+
+## Environment notes for this platform
+
+- The rea MCP server (`mcp__rea__*`) opens files read-only on the host and never executes targets. Use it for structure, strings, and symbol questions on either build; files must live under the shared data mount and rea takes host-side paths.
+- `ghidriff` needs Java plus a Ghidra install. Verify availability before promising a diff; if no diff toolchain exists, say so and stop.
+- PoC execution belongs in an authorized lab VM, never in the task container.
+
+## Completion self-check
+
+- [ ] every workflow step was executed, not just read
+- [ ] the diff, the inferred bug class, and the PoC artifacts are in the work dir with hashes
+- [ ] the patched build was actually tested and its clean result recorded

+description: "Invoke this skill when a task holds an LFI/file-inclusion finding on a PHP target (or needs to assess one) and the target may run PHP 5.4-8.5.11 with default session.upload_progress settings: turns a read-only LFI into verified RCE via the session-file-injection chain (CVE-2026-109618/109619), lab-first and gated by program policy. Also covers passive detection of the vulnerable configuration."

+
+# php2shell: session.upload_progress LFI-to-RCE (CVE-2026-109618/109619)
+
+Under an **authorized** engagement only. This skill upgrades an existing
+LFI/unsafe-include finding on a PHP target into RCE, or classifies the target
+as not affected, using the vendored PoCs under `scripts/poc/php2shell/`
+(upstream: ikow/php2shell-poc, MIT; see the LICENSE there).
+
+## Hard gates (read before touching any target)
+
+1. **Authorization**: the target must be inside the task's authorized scope.
+2. **Program policy first**: many programs exclude or do not pay for
+   recently-patched third-party/framework zero-days within ~14 days of the
+   patch release. PHP patched these in 8.2.35/8.3.36/8.4.27/8.5.12
+   (2026-10-21). CHECK the program's policy on component zero-days BEFORE
+   testing a live target, and reflect the policy in how the finding is claimed
+   (often "reportable, not payable" or payable only after the clause lapses).
+3. **Detection before exploitation**: fingerprint passively first (response
+   headers, error pages, X-Powered-By). Only targets on PHP 5.4.0-8.5.11
+   (any build with session.upload_progress enabled, the default) are
+   candidates.
+4. **Lab first**: run chain 1 against the local lab (`lab/setup.sh` builds a
+   vulnerable PHP 8.2 FPM+nginx environment) until the mechanism is
+   understood, then one-shot the authorized target.
+5. **Chains 2 and 3 (var_destroy UAF, serializer mismatch) are LAB-ONLY**:
+   never fire memory-corruption or serializer-confusion primitives at a
+   remote target. Detection of their preconditions is fine.
+6. **One-shot verification** on the target: prove execution once (a marker
+   echo), capture evidence, stop. No persistence, no further exploration
+   through the shell.
+
+## Chain 1 workflow (session file injection + LFI -> RCE)
+
+1. Start with the task's LFI finding: note the include path parameter and its
+   constraints (prefix/suffix, truncation, wrapper filters).
+2. Confirm the session path is reachable through that LFI: with
+   `session.upload_progress.enabled=On` (default), an in-flight multipart POST
+   with an attacker-named file field writes a session file under the session
+   save path containing the raw filename.
+3. Inject PHP into the uploaded **filename** (not the file content):
+   `verify_session_injection.py` demonstrates the full mechanics (session
+   fixation via POST body PHPSESSID, raw filename storage, inclusion).
+4. Race the session file's lifetime: include it through the LFI while the
+   upload is still in flight (or keep the upload connection open).
+5. Verify RCE with a single marker command; record the request sequence as
+   evidence.
+
+## Detection without an LFI
+
+The chains need an app-level file-inclusion primitive; without one the
+configuration is hardening-relevant, not exploitable. Report posture only.
