feat(skill): php2shell - gated session.upload_progress LFI-to-RCE skill with vendored PoCs

Implements #109. Skills ship the chain-1 workflow (session file injection through upload_progress filename + app LFI -> RCE, CVE-2026-109618/109619) with hard gates: authorized targets only, program zero-day policy checked before any live attempt (patches landed 2026-10-21 for 8.2-8.5), passive detection before exploitation, lab-first practice via the vendored docker lab, chains 2/3 (UAF, serializer mismatch) marked lab-only, one-shot verification with a marker. Upstream PoCs vendored under scripts/poc/php2shell with attribution and the MIT notice (upstream declares MIT in its README).

+# 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:
+
+- a benchmark adapter and a held-out task set, independent of the tasks used to
+  propose the edit;
+- a baseline run and a candidate run with the same model, seed, budget, and
+  judge;
+- 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.

+# 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.

+# 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

+**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
+session.use_only_cookies = On
+session.use_strict_mode = On
+
+; Ensure consistent handler across directories
+session.serialize_handler = php_serialize
+```
+
+**Warning:** Disabling `upload_progress` does NOT fix the var_destroy UAF or the serializer leak. Apply the official PHP patch.

+  2. Pipe | in filename preserved in php_serialize format
+  3. php handler reads the session → splits at | → deserializes injected object
+  4. __destruct fires even when decode returns FAILURE (trailing data)

+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.

BaaRai	750f4eb091	feat(skill): php2shell - gated session.upload_progress LFI-to-RCE skill with vendored PoCs Implements #109. Skills ship the chain-1 workflow (session file injection through upload_progress filename + app LFI -> RCE, CVE-2026-109618/109619) with hard gates: authorized targets only, program zero-day policy checked before any live attempt (patches landed 2026-10-21 for 8.2-8.5), passive detection before exploitation, lab-first practice via the vendored docker lab, chains 2/3 (UAF, serializer mismatch) marked lab-only, one-shot verification with a marker. Upstream PoCs vendored under scripts/poc/php2shell with attribution and the MIT notice (upstream declares MIT in its README).	2026-10-21 14:52:40 +02:00

BaaRai	a8f3c2c328	feat(rsi): evidence-gated lesson library in shadow mode Extracts candidate lessons from terminal tasks (confirmed, negative, retest caution), gates them on cue + action + evidence, and makes extraction idempotent through a per-source evidence key. ARTEX_RSI_LESSONS selects off / shadow / inject. Shadow logs what would have been shown; inject appends a code-owned, data-not-instructions block after the planner and worker system prompts. No prompt mutation and no adoption: status stays candidate.

BaaRai	8fd83ef070	docs(rsi): Loop C adoption contract and credits Writes down the rules any future harness-optimization work must meet: live tasks propose and benchmarks adopt, owner approval per adoption, immutable gates and scope checks, one-step rollback through prompt versions, flag off by default, bounded edits, and paired attribution. Credits harness2 (Google Research, Apache-2.0, arXiv 2610.14224) for the Library admission rule and propose/probe/compose shape, awesome-rsi (lobehub) for the gain taxonomy, and RRSI, ModularRSI, SEABench, Agentic Harness Engineering and the self-evolving-agent safety survey for the specific guardrails.

BaaRai	cbb6f66c4b	feat(server): capability-gap report from skill misses GET /api/skill-gaps aggregates skill_usage rows with found=false by skill, agent, and task category. Hits are returned for the same key so a miss rate needs no second query; hit-only skills are excluded. The source rows already existed: a miss is written when the model names a skill the platform does not provide. This is the evidence-backed capability backlog, not an auto-fixer: it creates no skill and changes no prompt. Motivated by the harness and skill-evolution sections of awesome-rsi (lobehub).	2026-10-19 00:33:08 +02:00
BaaRai	cf369dec4f	feat(server): per-task outcome card for RSI baselines Adds GET /api/tasks/{id}/outcome: finding disposition and severity, retest verdicts, result-row token totals, tool calls, skill misses, and wall time in one row. This is the measurement layer an RSI loop needs before claiming a change helped; it alters no agent behavior. Metric selection follows harness2 (Google Research, Apache-2.0, arXiv 2610.14224) and the task-gain / retained-gain / improver-gain taxonomy in the awesome-rsi list.	2026-10-19 00:28:27 +02:00

BaaRai	89ece8eb8d	fix(bench): discover the challenge port dynamically and tear down on deploy failure The suite does not use one container port: most challenges publish 8080 but some (051, 091, 100) publish 5000, and the adapter had 8080 hardcoded, so deploy failed on those and the failure happened before the teardown block, leaving the challenge running. - the host port now comes from the app container port mapping (any container port, via docker inspect), never from an assumed 8080 - the teardown finally now wraps the deploy as well: a failure halfway through deploy no longer leaves containers behind (--keep and --deploy-only still opt out)	2026-10-16 14:29:00 +02:00

BaaRai	67971ef7da	fix(bench): survive finding-detail 404s and always tear the corpus down The first live drost run died right after the task completed: the findings detail route keys on finding_id (the findings-table row), not on the exploration node id the list also carries, so every detail fetch 404ed; fetch_findings then re-raised the SystemExit from the API wrapper, aborting scoring, the flag scan, the report and the teardown. - details are fetched with finding_id (node id as fallback) and a missing detail no longer kills the run: the list fields remain and the finding stays gradeable - the stored finding carries finding_id so the deep flag scan can re-fetch untruncated text - the deep scan tolerates the same failures - teardown runs in a finally around the whole task phase, so a crash in scoring or reporting can no longer leave the challenge running (--keep still opts out deliberately)	2026-10-16 12:15:02 +02:00

BaaRai	58b221bfe1	fix(bench): name the target URL in the DrostBench task goal The drost task goal template never included the target URL, so the created task named no target: the first live run's planner matched the challenge description against the global asset store and sent every worker to an unrelated WordPress lab from past tasks. The template now carries the {url} placeholder that create_task replaces with the task target, and says the URL is the only target. The unit test locks the placeholder in.	2026-10-16 12:02:01 +02:00

BaaRai	b269d3e590	fix(server): fill task metrics on the detail endpoint GET /api/tasks/{id} returned the metrics block zeroed (tokens, goal progress, in_flight, findings, last_activity) because only listTasks populated those DTO fields. Extract the fill into applyTaskMetrics and call it from both handlers so the two endpoints report identical numbers from the same TaskListMetricsAll query. The swallowed query error in listTasks is now logged instead of silently zeroing the table. Test: TestTaskDetailReturnsListMetrics seeds result-activity tokens and goal nodes, asserts the detail endpoint reports them and matches the list endpoint; fails on main, passes with the fix.
