Ouroboros

Ouroboros is an open-source, general-purpose AI agent whose identity, durable memory, and history continue across tasks and restarts. It works on external projects, coordinates a live swarm of specialist agents, and can rewrite the implementation it runs on, including its code, architecture, prompts, tools, and dependencies. Reflection can also change how it understands itself without severing that continuity.

It runs as a native desktop app or through a headless CLI. The runtime keeps its repository, durable memory, history, and interface on your machine, while model inference can use remote APIs you configure or a local GGUF model.

Changing Ouroboros? Coding agents and people must read CONTRIBUTING.md before editing. It defines the required project context, verification, and separate-agent review flow.

To run tasks, configure at least one supported remote provider API key or a local GGUF model. The first-run wizard guides model access, review policy, and budget setup.

Optional CLI included with desktop downloads

The desktop packages already contain an optional CLI installer. On macOS, after copying the app to Applications, double-click Install CLI.command in the mounted DMG. On Linux use ./Ouroboros/bin/install-ouroboros-cli; on Windows use Ouroboros\bin\install-ouroboros-cli.cmd. These installers create a user-local ouroboros command without sudo. You do not need Python or uv.

Ouroboros bundles Claudexor as its local execution layer for delegated coding and hosted-agent review. Ouroboros owns the task, memory, review, and final integration, while Claudexor runs the selected connected coding harness and returns durable execution evidence. Explore Claudexor.

The technical report, Ouroboros: A Self-Developing Frontier Coding Agent with Reviewed Core Evolution, describes the reviewed core-evolution system, the 161-day Hope deployment, and the benchmark campaigns summarized below. Paper page · Hugging Face

The charts below are self-reported results on Terminal-Bench 2.1, OSWorld-Verified, and CL-Bench, measured against Codex, Claude Code, Cursor, and Hermes — on the same model where a matched pair was run, and against the public leaderboard where it was not.

---

Ouroboros first booted on February 16, 2026. During the following 48 hours, the repository advanced from the v4.1 line to v6.2.0. The self-authored record preserved from that period counts 32 evolution cycles. That first generation ran in Google Colab through Telegram and remains preserved on the legacy-google-colab branch and its original project page; the current generation carries the same identity into a native desktop and headless runtime.

⭐ Star Ouroboros to follow its next evolution. A star also helps more people find the project, trace its history, and take part in what it becomes.

Reviewed skills, transport bridges, tools, and widgets are available through OuroborosHub.

What Ouroboros Can Do

• Modify its implementation. Its editable surface spans application code, architecture, prompts, tools, and dependencies, while reflection can also reshape its living self-understanding.
• Evolve autonomously. Evolution campaigns turn selected improvements into reviewed changes that remain part of its Git history.
• Continue across restarts. Identity, memory, dialogue, knowledge, reflections, and version history form one ongoing biography.
• Think between requests. Background consciousness supports reflection, initiative, and preparation outside the immediate request-response loop.
• Coordinate a live swarm. Specialist agents can investigate or act in parallel, share task-tree findings, and return work for integration.
• Work on external projects. A separate Git workspace can receive the full task loop while Ouroboros keeps its own repository and governance boundary distinct.
• Operate through desktop or CLI. The native app and gateway-backed command line expose the same managed tasks, progress, artifacts, logs, and schedules.
• Organize long-running work. Project rooms keep working folders, journals, knowledge, task history, and conversations connected to the same identity.
• Use remote or local models. Supported provider APIs and local GGUF models can fill the runtime's configurable cognitive roles.
• Grow through reviewed extensions. Skills, transport bridges, widgets, MCP tools, and companion processes expand capability without folding every integration into the core.
• Keep self-change inspectable. Git history, review evidence, explicit protected surfaces, and restart checks make implementation changes traceable.

This list is an orientation, not a second specification. BIBLE.md defines Ouroboros's identity and constitutional boundaries; docs/ARCHITECTURE.md and docs/DEVELOPMENT.md are the current technical sources of truth.

Benchmarks

Ouroboros has reproducible self-reported state-of-the-art results on Terminal-Bench 2.1, OSWorld-Verified, and CL-Bench. In those model-matched results, it leads Codex, Claude Code, Cursor, and Hermes. The public SWE-bench Pro matched pair is a statistical tie with Codex CLI. A separate GAIA campaign reports 129/165 for Ouroboros and 131/165 for Claude Code, with strict pass@1 at 128/165 for both; its scrubbed trace capsule is still pending. Upstream review can take time, so open submissions are marked without delaying publication. Read every row as model plus harness because the same model can score differently inside a different harness.

Advanced installation

Normal desktop users can stop after the download and quick-start instructions above. The options below are for detailed Linux setup, headless use, and development.

Packaged Linux details

• Debian / Ubuntu / Astra Linux x86_64: download the .deb and run sudo apt install ./ouroboros_*_amd64.deb. It installs Git as a package dependency, installs Ouroboros to /opt/ouroboros, puts ouroboros on PATH, and adds a desktop entry plus an opt-in systemd user unit.
• Fedora / RHEL x86_64: download the generic .rpm and run sudo dnf install ./ouroboros-*.x86_64.rpm. It uses the same layout, Git dependency, and opt-in user unit as the .deb.
• RED OS 8 x86_64: download the red80 package and run sudo dnf install ./ouroboros-*.red80.x86_64.rpm. CI also attempts non-blocking install-and-run smokes on Astra Linux 1.8 and RED OS 8; inspect the tagged workflow run for their outcome.
• Other Linux x86_64: use the AppImage or the extraction-friendly tar.gz archive. Git must already be installed.

The native .deb and .rpm never enable or start their user service. It is an alternative to launching from the desktop entry and controls only instances started through systemctl --user. See the systemd user-service guide.

Install the Linux AppImage

User-level installation means copying the portable executable to a stable path and making it executable; it does not need root access. Ouroboros bootstrap still requires Git on the host:

VERSION=x.y.z
install -Dm755 "./Ouroboros-${VERSION}-linux-x86_64.AppImage" \
  "$HOME/Applications/Ouroboros.AppImage"
"$HOME/Applications/Ouroboros.AppImage"

The embedded desktop file and icon allow compatible AppImage integration tools to register that stable path with the application menu. The same file exposes the packaged CLI:

"$HOME/Applications/Ouroboros.AppImage" --cli status

If FUSE mounting is unavailable, extract and run ephemerally instead:

APPIMAGE_EXTRACT_AND_RUN=1 "$HOME/Applications/Ouroboros.AppImage"

Chromium and WebKit binaries are bundled, but their distro-level shared libraries remain host dependencies. If a browser engine reports missing libraries, use the native .deb/.rpm package where available, or extract the AppImage and let its bundled Playwright report/install the packages required by your distribution:

"$HOME/Applications/Ouroboros.AppImage" --appimage-extract
./squashfs-root/usr/lib/ouroboros/_internal/python-standalone/bin/python3 \
  -m playwright install-deps chromium webkit

Connected coding subscriptions

Use your existing Codex, Claude Code, or Cursor subscriptions for delegated coding and review. Ouroboros drives them through Claudexor, its bundled multi-harness engine. Connect accounts in Settings → Accounts and choose their roles in Agents; no separate Claudexor install is needed. Release artifacts carry the exact reviewed engine and Node archives. Source checkouts obtain those same pinned archives on first use.

Headless CLI with uv

For a user-level CLI/server install without cloning a working tree, uv can build Ouroboros directly from the contribution branch:

uv tool install "git+https://github.com/razzant/ouroboros.git@ouroboros"
ouroboros --help

The tool environment is isolated and exposes the ouroboros and ouroboros-web commands. Update or remove it with:

uv tool upgrade ouroboros
uv tool uninstall ouroboros

This Git-branch form follows the latest ouroboros commit and resolves the dependencies declared in pyproject.toml; uv tool install does not consume the repository's uv.lock. Replacing ouroboros after the @ with a reviewed full commit SHA pins the Ouroboros source revision, but dependencies are still resolved from pyproject.toml. Use the source setup below for a lock-verified environment, development, repository tests, and the complete browser extras, or use a platform release artifact for the packaged desktop runtime.

Develop or run from source

Clone the repository only when you plan to contribute, modify Ouroboros, run repository tests, or need a lock-verified development checkout. Normal users should use the packaged downloads above.

Requirements

• Python 3.10+
• uv 0.12.1 (the exact resolver version pinned by this checkout)
• macOS, Linux, or Windows
• Git
• GitHub CLI (gh), optional unless you use GitHub integration

Setup

Install the pinned resolver version:

curl -LsSf https://astral.sh/uv/0.12.1/install.sh | sh

Windows PowerShell:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/0.12.1/install.ps1 | iex"

git clone https://github.com/razzant/ouroboros.git
cd ouroboros
uv sync --locked --extra browser --group dev
source .venv/bin/activate

Windows PowerShell:

uv sync --locked --extra browser --group dev
.\.venv\Scripts\Activate.ps1

Run

ouroboros server

Then open http://127.0.0.1:8765 in your browser. The setup wizard will guide you through API key configuration.

Google Colab

Use notebooks/colab_quickstart.py as a Colab-compatible cell script when you need a source-mode runtime without the desktop UI. It keeps runtime data on Google Drive and preserves the original Colab path without making it the primary installation flow.

CLI / Headless

The ouroboros command attaches to the local runtime by default and starts one when --start is passed. It exposes managed tasks, progress streams, artifacts, logs, schedules, settings, skills, and evolution controls without duplicating the server's business logic.

ouroboros status
ouroboros run --start "2+2?"
ouroboros run "Summarize current runtime state"
ouroboros run --workspace /path/to/project --memory-mode forked --patch-out result.patch "Fix the failing test"
ouroboros tasks list
ouroboros logs tail progress --task-id <task_id>
ouroboros schedule add --name nightly-review --cron "0 2 * * *" "Run a maintenance review"
ouroboros schedule list

External workspaces may be ordinary folders or separate Git worktree roots, and may not overlap Ouroboros's own repository or data directory. Git-specific operations use a Git worktree; ordinary file and process work runs directly in a validated folder. Patch, streaming, detached-task, and schedule semantics are documented in the CLI help and the canonical architecture.

For Agents

Another agent, script, or CI job can invoke Ouroboros through the same gateway-backed CLI:

ouroboros run --start \
  --workspace /path/to/project \
  --memory-mode forked \
  --patch-out result.patch \
  --result-json-out result.json \
  "Investigate the task, act, and verify the result"

Use --jsonl for a machine-readable event stream and --detach when the caller will follow the task with ouroboros tasks watch <task_id> or inspect it with ouroboros tasks show <task_id>. External workspace runs keep Ouroboros's own repository and governance context separate, then export changes as reviewable patch artifacts.

To change Ouroboros itself, follow CONTRIBUTING.md: read docs/CHECKLISTS.md in full, and map BIBLE.md, docs/ARCHITECTURE.md, docs/DEVELOPMENT.md, and docs/DESIGN.md by their headings, reading every section relevant to your change in full before editing.

Configuration

The first-run wizard and Settings configure model access, cognitive roles, local models, review policy, runtime mode, budget, skills, and optional integrations. Ouroboros supports configurable remote providers, compatible endpoints, and local GGUF inference; every key and its shipped default lives in ouroboros/settings_defaults.py — with the clamped scales, model slots, reviewer routes and numeric limits in its sibling leaves, all re-exported through the ouroboros/config.py facade — and the same vocabulary is documented in docs/ARCHITECTURE.md.

The server binds to 127.0.0.1:8765 by default. Read docs/DEPLOYMENT.md before exposing it beyond loopback; non-local binds need OUROBOROS_NETWORK_PASSWORD or an explicitly trusted external access layer.

Run Tests

python scripts/run_tests.py                  # full local battery (same as `make test`)
python scripts/run_tests.py tests/test_x.py  # focused run

pyproject.toml is the direct-dependency authority and uv.lock is the cross-platform resolution lock. Release builds install the generated requirements-runtime.lock compatibility export into embedded interpreters that intentionally ship pip rather than uv. Build-only requirements are exported ephemerally from uv.lock and are not committed. The tiny requirements.txt file is only a pointer to that export for already-released managed updaters; it is not a second dependency declaration. After changing dependencies, refresh the reviewed lock and runtime export with:

uv lock
uv export --locked --no-dev --extra browser --no-emit-project --no-hashes --no-annotate --output-file requirements-runtime.lock

---

Build

Docker

docker build -t ouroboros-web .
docker run --rm -p 8765:8765 \
  -e OUROBOROS_NETWORK_PASSWORD='choose-a-password' \
  -e OUROBOROS_FILE_BROWSER_DEFAULT=/workspace \
  -v "$PWD:/workspace" \
  ouroboros-web

Docker runs the web runtime, not the native desktop shell. It bundles Chromium and WebKit support; use docs/DEPLOYMENT.md for network and container policy.

Release tag prerequisite

Platform build scripts package only a commit already tagged with v$(cat VERSION). Tag the exact release commit first:

git tag -a "v$(tr -d '[:space:]' < VERSION)" -m "Release v$(tr -d '[:space:]' < VERSION)"

scripts/build_repo_bundle.py verifies the tag and embeds the source binding into the packaged repository bundle. Signing, notarization, bytecode sealing, and CI invariants are documented in docs/ARCHITECTURE.md and docs/DEVELOPMENT.md.

macOS (.dmg)

bash scripts/download_python_standalone.sh
OUROBOROS_SIGN=0 bash build.sh

Output: dist/Ouroboros-<VERSION>.dmg, containing Ouroboros.app, an Applications shortcut, and Install CLI.command. Omit OUROBOROS_SIGN=0 when a Developer ID signing identity is configured.

Linux (.AppImage and .tar.gz)

bash scripts/download_python_standalone.sh
bash build_linux.sh

Outputs: dist/Ouroboros-<VERSION>-linux-<arch>.AppImage and the extraction-friendly dist/Ouroboros-<VERSION>-linux-<arch>.tar.gz. The AppImage needs host Git; run it after chmod +x, or pass --cli to reach its bundled CLI. If FUSE is unavailable, set APPIMAGE_EXTRACT_AND_RUN=1 when launching it. The tarball contains ./Ouroboros/bin/install-ouroboros-cli. If bundled browser tools need host libraries, run ./Ouroboros/_internal/python-standalone/bin/python3 -m playwright install-deps chromium webkit from the extracted tarball.

On a build host where system packages are managed separately, set OUROBOROS_SKIP_PLAYWRIGHT_INSTALL_DEPS=1; Chromium and WebKit are still downloaded and bundled, but the build does not invoke sudo to install host libraries.

Linux (.deb and .rpm)

Wraps the payload build_linux.sh just produced, so run it afterwards:

sudo apt-get install -y dpkg-dev rpm   # rpm provides rpmbuild
bash scripts/build_linux_packages.sh

Output: dist/ouroboros_<VERSION>_amd64.deb, dist/ouroboros-<VERSION>-1.x86_64.rpm and dist/ouroboros-<VERSION>-1.red80.x86_64.rpm (RED OS 8). All three declare Git as a runtime dependency and install to /opt/ouroboros with a /usr/bin/ouroboros symlink, a desktop entry, and an opt-in systemd user unit. The Linux launcher is built by the bundled portable Python so the build runner cannot raise its glibc floor. bash scripts/smoke_linux_packages.sh official <deb> <rpm> <red80-rpm> installs all three through apt or dnf in Ubuntu 22.04 and Fedora 42 containers, resolves Git, verifies the installed unit, and checks both the real CLI and a bounded desktop-launcher start; this lane gates the release. Swap official for vendor to repeat the check on Astra Linux 1.8 and RED OS 8 images from the vendors' own registries — that lane runs informationally in CI, so an outage at a third-party registry cannot block a tagged release.

Windows (.zip)

powershell -ExecutionPolicy Bypass -File scripts/download_python_standalone.ps1
powershell -ExecutionPolicy Bypass -File build_windows.ps1

Output: dist\Ouroboros-<VERSION>-windows-x64.zip, containing Ouroboros\bin\install-ouroboros-cli.cmd.

Architecture and Runtime Data

The native launcher starts a web runtime and supervisor-managed agent workers. The agent core lives in ouroboros/, the interface in web/, the process plane in supervisor/, and the runtime's durable identity, state, history, logs, and skills under ~/Ouroboros/data/.

The full component map, data flow, API surface, storage layout, safety boundary, and operational rationale live in docs/ARCHITECTURE.md. Deployment details live in docs/DEPLOYMENT.md.

Runtime Commands

Command	Purpose
/panic	Stop the runtime and its managed processes immediately.
/restart	Restart without automatically resuming the active owner task.
/status	Show workers, task queue, and budget state.
/evolve on|off	Start or stop autonomous evolution.
/review	Queue a deep constitutional and architectural self-review.
/bg start|stop|status	Control background consciousness.

Philosophy

The 13 Constitution principles — Agency, Continuity, Meta-over-Patch, Immune Integrity, Self-Creation, LLM-First, Authenticity & Reality Discipline, Minimalism, Becoming, Versioning and Releases, the absorbed Iterations / Spiral lineage, and Epistemic Stability — are defined in full in BIBLE.md. That file is the constitutional SSOT (Bible P4 Ship-of-Theseus protection) and this README intentionally does not paraphrase it.

Contributing

External contributions are welcome. See CONTRIBUTING.md for the complete agent-first workflow. Open pull requests against lowercase ouroboros, leave release-version allocation to maintainers, and have a separate agent context review the final diff. Any coding harness or configured review route may produce the evidence; if none is available, record NOT_RUN and the reason.

Version History

Version	Date	Description
7.4.4	2026-09-21	fix: restore annotated tags in Android packaging and stabilize release checks. CI retains independent failures, browser tests use portable focus and distinct subagent routes, and release metadata stays synchronized.
7.4.2	2026-09-21	fix: fetch annotated release tags before packaging and keep cross-platform release gates honest.
7.4.1	2026-09-21	fix: collect independent CI and diagnostic release-build failures without weakening publication gates. Failed test steps continue to their independent checks, valid tags retain release metadata for diagnostic desktop builds, and publication remains fail-closed on required results.
7.4.0	2026-09-20	feat: add an honest desktop attention cue for live notifications. The optional launcher bridge can raise the existing desktop window and request one platform system sound, returning explicit native/unsupported/window_only/unavailable facts; it does not claim Notification Center delivery, run after close, or add a tray/background process. Browser banners and in-app toasts remain the fallback, with capability text visible in Settings. Focused native, launcher and notification tests cover the seam.
7.3.0	2026-09-19	feat: notifications can pull you back to a question or a finished task while a client is running (#1122). Settings → Appearance gains a notification block next to the theme: a master switch, the two required categories (a question or decision is waiting for you, a task finished or stopped), a model-chosen category for messages Ouroboros sends while it works, a separate off-by-default toggle for ordinary replies in Main, sound, an off-by-default show-the-text choice and a test notification. The choices are stored per client exactly like the appearance choice, never reach the server, and do not make the settings draft dirty. Delivery is page-level: a system banner where this client exposes one and permission is granted, otherwise the in-app surface plus one short tone, with the status line saying which surface you actually have; either way a click opens the source. The new web/modules/notifications.js keeps classification and the delivery gate pure over one live frame plus the stored preferences, and takes ONE subscription per client on the shared socket — not inside a chat instance, which dies with its room, so a Project the owner never opened still reaches him; web/modules/chat.js is untouched. Only live frames reach it, so a reload cannot re-notify without any stored notification state. A finished managed root is recognised on the shape it actually arrives in (a live task_done log frame) as well as the authored summary, and a conversation turn's own ending stays the ordinary-reply category instead of claiming a task finished; all of them collapse to one key per task. A child task never notifies the owner: it escalates to its parent, and lineage is read from the delegation facts frames carry because the terminal frame has none. Importance needs no new host field and no second model call: the existing proactive-message discriminator is the signal. Policy and its disclosed limits have one canonical home in docs/DESIGN.md §9 — including that each open window is its own client, that an event during a dropped socket never rings, and that no OS permission, Do Not Disturb or platform limit is bypassed.
7.2.1	2026-09-19	fix: an optional argument that asks for nothing is no longer a refusal, reflection keeps the evidence, and plan review stops speaking for the wrong plan (#1114). A filled optional value that asks for nothing now takes the omitted path with a single receipt line in knowledge_read, schedule_followup and delegate_wait, and a value that asks for something unservable is refused once, typed, naming the field and the repair in schedule_followup and delegate_wait; get_task_result publishes an invalid source range as an argument error naming the complete length and the range received instead of ok, and the escalate quiz refusal is typed and says the quiz was not sent. The receipt line and the typed refusal live in the new ouroboros/tools/arg_feedback.py. knowledge_write with an empty expected_revision creates a new note while overwrite protection on an existing note is unchanged, and a blocked link in send_links stays a policy denial and now states that no links were sent. Post-task reflection sees the calls and outcomes as the trace retained them, with a pointer to the exact stored record, compares full content when detecting repeats, and preserves the recovered status-classification corrections. In plan review a historical critic is evidence labelled as the earlier plan's and can no longer overwrite cycles_exhausted; an author stop is no longer described as work that proceeded under advisory enforcement; self-check outcomes are read from one trace row, so reused provider call ids cannot attach another call's error to a successful call after context compaction. The escalate and quiz wait bound keeps the 7.2.0 semantics. Known and disclosed in docs/architecture/06-agent-core.md: the web plan-review group can still present an earlier critic's verdict as its own and reads a spent review cap only from the wave.
7.2.0	2026-09-19	feat: Light, Dark and System appearance, review that reads the repository instead of a packed snapshot, and one fast local test battery. The web UI gains a client-local Appearance choice — Light, Dark or System — applied before first paint in the app and the onboarding wizard and carried through in-page charts, diagrams and host-rendered widget charts, while framed skill widgets keep their own colours (#1107). With no saved choice the UI follows the system scheme, so an existing install on a light OS opens in Light until Dark is chosen; to remember the choice the desktop shell now keeps website data, including cookies, and a desktop app that only took in-app updates remembers it once the 7.2.0 installer has been installed. Project questions are one row in Main and become a card only while the task waits (#1106). Scope review retrieves what it needs from the repository rather than receiving one packed snapshot (#1043); plan review keeps paid feedback (#1051), acceptance review keeps its rework controls, final review text and explicit author completion (#1042, #1069, #1089), and system review mail no longer reopens accepted results (#1088). python scripts/run_tests.py is the one documented local battery: it runs the node lane first, then every default-lane test in one parallel run (#1101). First-run setup recovers subscription sign-in and model discovery (#1099), and Finish stays usable after a refused Main-reviewer recovery (#1100); delegated requests are stored by reference and keep pending recovery (#1067); terminal outcomes, usage accounting, cancellation provenance, task relay authorship and process environments are preserved end to end (#1054, #1064, #1083, #1098). Also: the managed Claudexor runtime moves to 3.12.4, an experimental Android host with optional release artifacts (#873), bounded Cowork Bench meter reads that preserve interrupted work (#1044), chat composer, Activity row and project-link fixes (#1063, #1095), clearer Presence delivery (#1053), subagent scheduling refusals (#1092), settings and helper-history reporting (#1090), and scope-review context logging from a community contribution (#752).
7.1.0	2026-09-17	feat: memory that understands people, Background Consciousness as an ordinary Main turn, and a chat that leads with narration. Memory keeps an understanding of people in front of the mind through resident summaries, one memory shared by every room and honest consolidation (#910). Background Consciousness becomes an ordinary Main turn on an alarm clock (#988, closing the class behind #654). Chat blocks lead with narration while tool calls fold into one evidence row (#1007); task cards follow their work and treat acceptance review as advice to Ouroboros (#970); question pointers say whether an answer is wanted and show the recorded answer (#1025); the unified UI control system, source picker and model chooser name models and accounts truthfully (#768, #862, #890). Planning is asynchronous and Swarm tasks are admitted directly (#851); delegated work survives durable cancellation (#850); a task's own reviewer is never swept as its delegation (#1008); semantic duplicate vetoes leave subagent admission (#887); Presence profiles work in an owner-selected folder (#941). Prompt caches extend through an append-only acceptance observation and a shared Codex cache key per install and model (#929, #1015). Update letters include merged branch changes (#1003), the owned Claudexor daemon latches failed starts with a typed diagnosis, and the managed runtime advances to Claudexor 3.12.1 (#891, #962), alongside Windows, platform-installation and UI-smoke repairs.
7.0.0	2026-09-08	v7: a modular runtime with full ordinary-conversation tools, complete delegated inputs and visible owner dialogue. Main and Project conversations retain their chosen tools and working folders; required owner waits preserve the live browser without occupying pooled execution capacity. Publish admission is visible in its intended chat, and GitHub/image/plan failures retain their actual causes. Planning advice stays optional; source-backed evidence, separate host notices and exact-workload test reuse preserve honest review without new approval machinery. Integrates the subscription model and account-role controls, owned startup/restart custody and cross-platform repairs, with Claudexor pinned to 3.10.1.
6.113.5	2026-08-31	fix: browser cleanup after a timed-out tool is generation-safe (integrates community PR #429 by @mikemikimike, closes #409). A stateful-tool timeout now retires the whole browser generation: the shared state slot is replaced with a fresh object, the abandoned worker keeps writing only into its retired one, and the close is queued on the retiring executor so it always runs on the owning worker thread — including the already-settled race — with the cognitive lease closing after that cleanup. A late infrastructure-error retry that observes a replaced generation closes only its own retired session, so it can no longer cross-thread-kill the next command's browser. Closes the follow-up findings of the #440 post-merge audit; the never-settling-worker session leak stays a disclosed residual of in-process Playwright.
6.113.0	2026-08-29	feat: delegation by construction — the nanny charter, typed $0 terminals, truthful executor cards, and honest route health (Claudexor runtime 3.9.0). An agent_session child now IS work on its harness: the host pre-starts the physical leaf through the same configured delegate_start wrapper BEFORE the nanny's first LLM round and never waits — her first round arrives with a live configured_session_started receipt, waiting is her own delegate_wait decision, and children may run beside the leaf. A definite refusal to start (typed pre-POST, dispatch-blocked, engine-rejected — with a custody-handle guard that always prefers a model episode over a false terminal) ends the task typed and unrun at $0; ambiguity always wakes the model, and durable zero-run/unknown-evidence fences outrank blocked terminals. Zero-run receipts narrow to incomplete|unknown, actor cleanliness requires a SUCCEEDED delegated run (children are evidence, never a completion path), unreadable custody projects typed unknown all the way into the finalization nudge, and only acts of delegation reset the economics baseline (the reminder-storm class is dead). route_health stops refusing on aggregate doctor status — admission belongs to the engine; the owner's enabled toggle stays a typed route_disabled. Acceptance sees substrate facts as visibility with zero gates. The executor chip tells the run truth for the whole lifecycle (dispatched → counted N ok, M failed → evidence honesty), all-failed can never render clean, actual_substrate reaches the wire, and the terminal evidence frame survives chat-0/A2A routing. The pinned Claudexor runtime moves to 3.9.0: per-vendor quota pacing with typed Retry-After floors (a poll 429 is never a quota fact), honest foreground cooldowns, first-429 short-circuit, cached accounts default, and the cursor delegation belt (live-E2E proven). This tag also carries the untagged 6.111.0 and 6.112.0 (P13 Emergence) below, and heals the branch's latent size-ratchet debt root-cause (settings_integrity extraction, cybergym module splits, regenerated manifest).
