Changelog

3.0.0

• Made the Windows workflow smoke harness use the repository virtual-environment runtime when available, avoiding false failures from a dependency-free system Python.
• Made background execution restart-safe by recording PID creation times and deadlines, refusing to signal reused PIDs, recovering matching processes, and marking missing processes as lost; new pending batches now use collision-resistant UUIDs.
• Made burst execution atomic at admission: every command is preflighted before launch, required sync credit is reserved under one lock, and unused reservations are returned after partial batches.
• Fixed target extraction for dotted identifiers and direct /dev/tcp//dev/udp redirections, and prevented network-capable local-looking commands from bypassing execution accounting.
• Made interrupted skill preparation recoverable with expiring reservations and stale-owner protection; batch review now remains tied to the delivered execution receipt.
• Stabilized the core engagement workflow: domain/URL-only scopes now validate, runtime execution cannot substitute another scope file, PTT/review CLI contracts carry skill metadata, and review reuses the active delivered binding.
• Added receipt-backed skill routing, delivery, task binding, browser enforcement, Kali auto-backend selection, proof-based finding review, and semantic anti-stuck enforcement.
• Replaced marker-file authorization with two-turn skill preparation and receipt diagnostics; legacy markers can only infer a unique session ID during migration.
• Allowed direct host-local init-engagement --host bootstrapping, persisted runtime session identity before skill delivery, and blocked shell-indirection workarounds.
• Scoped skill cooldowns to Hermes model API requests so the next tool-loop continuation unlocks automatically, while batch review no longer replaces the active execution-skill binding.
• Migrated guard tool schemas and parameter validation to Pydantic v2.
• Replaced platform-specific process termination with cross-platform psutil process tree traversal and cleanup.
• Upgraded target IP/CIDR scope policy arithmetic to netaddr.IPSet and RFC 3986 URL parsing to yarl.
• Replaced shell regexes in terminal policy with bashlex AST tokenization and command parsing.

2.0.8

• Expanded Duck Store benchmark challenges from 14 to 20 article-parity vulnerabilities, matching Redpick's verified findings across 7 categories with correct severity distribution.
• Renamed benchmark engagement prompt from anti-walkthrough.md to engage.md and added a post-engagement report.md prompt that runs the scorer and generates a comprehensive benchmark report.

2.0.7

• Added a Duck Store benchmark harness: 4-file suite (score.py, challenges.json, scope.yaml, engage.md) to evaluate Violin against escape.tech's Duck Store with repeatable, evidence-gated scoring.
• Rewrote score.py with 8 evidence-gated fixes from the first benchmark run: corrected PTT path (state/ptt.md), hypothesis status per-block parsing, word-boundary pattern matching, HTTP proof-signature quality gate, auditable per-challenge output, honest compliance reporting (empty history reports UNKNOWN), calibration dry-run mode, and coverage-vs-quality split in output.
• Added explicit model section to config.yaml; profiles do not inherit the default model configuration.

2.0.6

• Resolved the current CodeQL standard quality findings by making intentional exception fallbacks explicit and removing unused test and hypothesis variables.

2.0.5

• Restored exact-repeat detection for execution history entries with receipt paths and added unambiguous command-length metadata while retaining compatibility with existing history files.

2.0.4

• Hard-blocked callback and research endpoints when supplied as primary assessment targets while preserving their approved secondary-only use, including burst execution.

2.0.3

• Fixed raw-terminal compound-command classification so every pipeline, logical, semicolon, and newline segment is checked independently, and package/source exemptions require every URL in the segment to use an approved source host.

2.0.2

• Restricted all GitHub Actions workflow tokens to read-only repository contents, resolving the three least-privilege code-scanning alerts without changing workflow behavior.

2.0.1

• Upgraded the pytest development dependency to 9.0.3 or later to address CVE-2025-71176 insecure temporary-directory handling.

2.0.0

• Added model-visible violin_status diagnostics, phase-aware 10/20-command sync windows, a 350-iteration profile budget, and atomic violin_review_batch reconciliation with optional receipt-backed finding output.
• Fixed explicit PTT task creation so the requested phase controls the row's actual table placement, and unified CLI/plugin PTT review state.
• Removed message-count heartbeat locks; executed-command heartbeat checks remain phase-aware and are suppressed during exploit-heavy phases.
• Made the existing violin_exec contract explicit for every installed non-interactive Kali/Parrot CLI tool, and removed the partial target-tool name list from raw-terminal classification in favor of generic target-literal detection.
• Reorganised the guard into focused top-level modules under plugins/violin_guard/, with separate history, result, execution, state, target, and service responsibilities.
• Split web-injection and access-control playbooks into the on-demand web-attacks and access-control skills while keeping pentest as the engagement orchestrator.
• Required an explicit primary target at the command boundary and added operator-approved callback hosts that cannot be promoted to assessment targets.
• Added guarded listener execution and audited pending-batch rebinding without weakening the required PTT review and synchronization checkpoint.
• Added engagement-bound audit receipts for Hermes execute_code calls, while documenting terminal detection as best-effort rather than scope enforcement.
• Replaced regex-based target parsing with Python standard-library shell, URL, IP/CIDR, and MIME parsers; this keeps scope enforcement dependency-free while reducing parser ambiguity.
• Kept target parsing and target-scope enforcement in plugins/violin_guard/targets.py, leaving command.py focused on policy orchestration.
• Allowed violin_record_ptt to start one untouched phase-bound task, removing the initial active-task deadlock while retaining fail-closed batch reviews.
• Made hypothesis parsing field-order independent and fixed template rewrites so recorded hypotheses are never written inside the template comment.
• Clarified typed nmap all-port input: use ports: "1-65535", not the -p- flag form.
• Bootstrap engagement-local exploits/ and phase evidence directories, and direct local scripts and output away from /tmp while preserving explicitly labelled remote-target /tmp payloads.
• Fixed target extraction so local dotted output/script names are not treated as hosts, and Bash /dev/tcp or /dev/udp endpoints retain their full host and port boundary.
• Canonicalized hypothesis IDs supplied as H-001, removed malformed duplicate headings on rewrite, and compare scoped hypothesis targets correctly when they include a URL or port.
• Kept review binding fail-closed while removing the need to manually copy an opaque pending batch ID into every PTT note.

1.3.1

• Enforced scope authorisation, exclusions, phase-aligned PTT tasks, and relevant hypotheses at the execution boundary.
• Made synchronization credits apply to all target-touching commands and bound reviewed batches to their captured PTT task.
• Serialized guard state transitions, fixed isolated plugin imports, and made release and PowerShell smoke checks fail reliably.

1.3.0

• Consolidated Violin Guard into a Hermes-native plugin.
• Made command history executor-owned and PTT review explicit.
