AI-LSC Changelog

v3.3 — Registry git-URL sync + bandwidth-aware git-pull + ComfyUI

Patch release over v3.2. No schema changes, no UI reorganisation, no wiring-graph churn — only the 10-layer registry's installer URLs are touched, plus the git install/update logic in runtime/installer.py, plus a new ComfyUI registry entry, plus version strings and a per-file change log.

What changed

The 10-layer registry layer files had drifted from the systems-architect reference (ai-stack-guide-v12.md, "Approaching the Local AI Stack Like a Systems Architect" by Jeremy Anderson). 52 installer URLs were either pointing at placeholder repos (github.com/nicely-done/<tool_id>, clearly never intended to ship) or at wrong upstreams (e.g. airllm pointed at liguodongiot/llm-airforce; llamacpp pointed at ggerganov/llama.cpp instead of the current ggml-org/llama.cpp). Three tools the v12 md lists as git / git_node (pm_skills, agno, openhands) were registered as uv package-manager installs — wrong, since the user manually tested every entry in the md by cloning the github repo. Four registry-only tools (algory, atlas_os, eagle_eye, glassmind) had only placeholder URLs because web search could not find their official upstreams; the user provided the URLs directly. ComfyUI was referenced in the ai-image-gen-local.json stack template but had no registry entry.

This release:

  • Brings every git-ish installer into agreement with the v12 reference.
  • Adds pkg fields to the 6 script-type installers that reference github release tarballs.
  • Resolves 10 registry-only git tools to their official upstreams via web search.
  • Switches the 3 type-mismatch tools to proper git/git_node installs.
  • Resolves the 4 previously-unresolved registry-only tools to the user-provided official upstreams.
  • Adds a ComfyUI registry entry (Level 10, git:comfy-org/comfyui).
  • Hardens the git installer runtime to be bandwidth-aware.

Five categories of patches (52 total)

  • A (28) — git / git_node / custom installer pkg URL corrected to match the v12 markdown reference. See docs/REGISTRY-URLS-v3.3.0.md for the per-file old → new URL table.
  • B (6) — script-type installers (fabric, grafana_alloy, llamafile, meilisearch, ollama, qdrant) get a new pkg field referencing the github repo, while the existing working cmd (curl release tarball, etc.) is left untouched.
  • C (10) — registry-only git tools with no v12 markdown entry resolved via web search:
    • agent_reach → Panniantong/Agent-Reach
    • everos_memory → EverMind-AI/EverOS
    • headroom → headroomlabs-ai/headroom
    • mnemo_cortex → GuyMannDude/mnemo-cortex
    • nightshift → johndaskovsky/nightshift
    • openbrain → NateBJones-Projects/OB1
    • turbovec → ryancodrai/turbovec
    • crossplane → crossplane/crossplane
    • keycloak → keycloak/keycloak
    • dma → distcc/distcc (closest parent project; DMA has no separate public repo)
  • D (3) — type-mismatch fixes (md says git / git_node, registry had uv with package name):
    • pm_skills → git:https://github.com/product-on-purpose/pm-skills
    • agno → git:https://github.com/agno-agi/agno
    • openhands → git_node:https://github.com/All-Hands-AI/OpenHands.git
  • E (4) — user-provided URLs for the 4 previously-unresolved registry-only tools (web search could not find these; the user provided the official upstream URLs directly):
    • algory → aryaghan-mutum/algory
    • atlas_os → atlas-os/atlas
    • eagle_eye → thoughtfuldev/eagleeye
    • glassmind → khodges42/glassMind

New tool entry (1)

  • ComfyUI (user_interfaces.py): ComfyUI was referenced in the ai-image-gen-local.json stack template but had no registry entry before. Added as a Level 10 (Human Interface & System Operations) tool with installer git:https://github.com/comfy-org/comfyui, launcher python main.py --listen 0.0.0.0 --port 8188, deps [cuda], license GPL-3.0. Total registry size is now 187 tools (was 186).

Runtime: bandwidth-aware git-pull-on-update

runtime/installer.py's install_git and install_git_node already ran git pull --ff-only if the destination dir existed, but the existence check was os.path.exists(dest) — True for any dir, not just a git working tree. An empty or non-git dir at the destination would cause git pull to fail and abort the install. Hardened:

  1. Check os.path.isdir(dest/.git) to confirm a real git repo.
  2. On pull failure (diverged branches, network errors, corrupted index, etc.), move the old dir aside to <dest>.bak.<unix_ts> and re-clone fresh — so the install always ends in a usable state instead of leaving a half-broken tree.
  3. If the dest dir exists but is not a git repo, back it up and clone fresh.
  4. Log clearly which path was taken (pulled / re-cloned / new clone / non-git-dir backed up).

Effect: re-running install on a tool that's already cloned only fetches the diff (a few KB / MB), not the entire repo. This is the bandwidth-saving behaviour the user asked for.

Intentionally NOT touched

  • apex (md says pip — https://github.com/NVIDIA/apex): kept as uv:apex (pip-installed). The md's pip installer type is authoritative and the user did not call this one out.
  • 12 git-ish installers that already matched the v12 reference (anythingllm, dify, heretic, homelab, invokeai, koboldcpp, librechat, mcp_drift_state_tracker, openjarvis, paperlessngx, synapscli, wayland_ai) — no change needed.
  • 3 registry-only git tools with real-looking URLs already in place (goose → block/goose, nvidia_agent_skills → NVIDIA/agent-skills, picode → jasonjmcghee/picode.git) — no change needed.

Versioning & docs

  • pyproject.toml: 3.2.0 → 3.3.0
  • src/ai_lsc/constants.py: APP_VERSION 3.2.0 → 3.3.0 (APP_CODENAME unchanged: "Decalogue")
  • New file: docs/REGISTRY-URLS-v3.3.0.md (per-file old → new URL table, also serves as a release audit trail).
  • gitcommit rewritten for v3.3.0.

Verification

  • All 94 Python files under src/ AST-parse cleanly.
  • Registry extractor re-imports every patched layer module and confirms all 52 patches landed + the new ComfyUI entry. Total registry size: 187 tools (was 186).
  • Each old pkg URL string was unique within its file and matched exactly once — no blind global replaces.
  • Each script-type pkg-field injection matched exactly one installer block (Python AST-parses after each injection).
  • install_git / install_git_node hardened: the new logic branches on os.path.isdir(.git), falls back to re-clone on pull failure, and uses import time for backup-dir timestamps. All confirmed present in runtime/installer.py.
  • 0 nicely-done placeholder URLs remain in the registry.

v3.2 — 10-Layer Systems Architecture Taxonomy completed

Finishes the taxonomy re-org that was started (but stalled) on top of v3.1.1b: the whole codebase now speaks the unified 10-layer taxonomy from the systems-architecture review (POSIX/Unix philosophy, bare-metal process hierarchy). The partial migration had already rewritten constants.py (NAV_LAYER_ORDER) and db_manager.py (CATEGORY_MAP); this release completes every remaining surface, repairs the damage the interim tooling caused, and reconciles the registries. Validator reports 0 errors on both the 108-tool defaults seed and the 186-tool merged layer registry; wiring graph validates with 0 errors.

New layer ladder (11 → 10)

L1  Host Platform & Infrastructure          L6  Multi-Agent Orchestration Runtimes
L2  Development Runtime & Environment       L7  Agentic Software Engineering & Sandboxes
L3  GPU Acceleration & Optimization         L8  Decentralized Knowledge & Vector Stores
L4  Local Inference Engines                 L9  Data Extraction & Pipeline Harvest
L5  Intelligent API Routers & Proxies       L10 Human Interface & System Operations

The 11-layer model's Security and Observability strata dissolve: security daemons (keycloak, vault, fail2ban, edge/proxy daemons) are host platform infrastructure (L1); scanners/policy/audit tooling (trivy, clamav, opa) and telemetry (btop, grafana, prometheus, opik) are system operations (L10). Routing merges into Intelligent API Routers & Proxies (L5). Vector/graph stores and agent memory move out of Knowledge Management into L8; document/crawl/transcode pipelines become L9; IaC and cluster automation land in L10.

Registry

  • registry/defaults.py rebuilt as the 108-tool 10-layer seed from the master-target registry: new level/layer/role/category plus the richer descriptions. Operational metadata (real installer pkgs/URLs and cmds, post_install/update_cmd/env_overrides, launchers with correct binary names and systemd-for-daemons, dependency edges, curated flags, SPDX licenses, filesystem blocks) is preserved from the previous registry — the master-target file had systematically replaced installers with placeholder URLs, dropped script cmds (validator errors), wiped all dep edges, and renamed binaries (rg → ripgrep, systemd → tmux serve stubs). curl|sh installer policy markers are untouched (see whatremains.txt, C-05).
  • 11 modular layer files realigned: 185 tools migrated to the 10-layer taxonomy (107 shared tools take their structural fields from the master registry; the other 78 classified explicitly).
  • kanban reconciled: it existed only in defaults.py (the canonical source is the layer files), so it is now declared in layers/user_interfaces.py as well (L10, Sprints Manager). Merged registry: 185 → 186 tools.
  • n8n keeps its explicit L10 placement (visual flow canvas) and moves to the Workflow (Visual Builder) category so the categorisation cascade agrees with the registry.
  • n8n/odysseus filesystem blocks (previously only in the old defaults) are preserved in layers/orchestrators.py.
  • The open_webui/openwebui orphan-flagging gap from the TODO is confirmed moot: only openwebui exists and it is wired.

Stack wiring

  • stack/connections.py: 92 static StackWiring(layer=...) values migrated to the 10-layer names; the 5 loop-based bulk allocations now resolve layers dynamically via _wiring_layer(_tid) (DEFAULT_REGISTRY lookup + _WIRING_LAYER_SUPPLEMENT for wired tools outside the seed registry), so the wiring graph can never drift from the taxonomy again. Section header comments map the old L1–L13 sections to their new homes. Wiring-vs-registry layer mismatches: 0 across 137 wirings.

UI

  • ui/pages/db_manager.py repaired and migrated: the interim migration had truncated the file from 1300 to 222 lines (syntax error at the CATEGORY_MAP tail; the entire DB-manager dialog/table implementation was lost). The canonical 1.3 k-line implementation is re-established in-tree, with its CATEGORY_MAP migrated to the 10-layer taxonomy.
  • Categorisation cascade extended to 221 categories: the master map (105) + 43 categories for the classified tools + 73 preserved categories from the v3.1.1b cascade, translated to the 10-layer taxonomy with their curated roles. Every category used by the 186 registry tools is covered; cascade and registry agree on layer for every tool.
  • ui/pages/db_manager_category_map.py regenerated to match.
  • registry/validator.py now enforces level range 1–10.

Docs & tooling

  • README layer table + tool counts updated to the 10-layer taxonomy (186 tools); quickstart's "13-layer architecture" reference fixed.
  • Layer-file module docstrings note the 10-layer realignment.
  • One-shot migration utilities (apply_taxonomy_migration.py, scripts/apply_10layer_taxonomy.py, and the three scripts/backfill_*.py license/flag backfills) retired post-apply in the MoE QA pass — they were idempotent and would have left dead code sitting in the tree.

Verification

scripts-style checks all pass: 100 Python files AST-parse; validator 0 errors (defaults + merged + wiring graph); level/layer consistency holds across defaults, layer files, CATEGORY_MAP, and STACK_WIRINGS; NAV_LAYER_ORDER matches the taxonomy; guardrails clean; headless package import + RegistryManager first-boot/second-run bootstrap verified (186 tools seeded to ecosystem.json, structural sync clean).

v3.1.1b — taxonomy re-org: Routing promoted to a first-class layer (11 layers), canonical 24-dir /mnt/AI layout

Promotes the Routing layer to a first-class stratum — distinct from Orchestrators — between Engines (who serve weights) and Orchestrators (who build agent workflows on the OpenAI-compat endpoint Routing provides). Aligns the backend to the revised canonical /mnt/AI/ directory tree. No tool count change (185 tools); validator still reports 0 errors.

New layer ladder (10 → 11)

L1  Host Platform          L7  Security
L2  Development Env        L8  Observability
L3  GPU Runtimes           L9  User Interfaces
L4  Engines                L10 DevOps
L5  Routing                L11 Knowledge Management
L6  Orchestrators

NAV_LAYER_ORDER inserts Routing between Engines and Orchestrators — engines serve weights, routing proxies/load-balances/meshes them into one OpenAI-compat endpoint, orchestrators build agent workflows on top.

Tool moves (18 tools, all layers/levels updated)

tool_id Old New
litellm L5 Orchestrators (Proxy / API Gateway) L5 Routing
9router_proxy L5 Orchestrators (LLM Router) L5 Routing
meshllm L5 Orchestrators (LLM Mesh) L5 Routing
dify L5 Orchestrators (Pipeline) L5 Routing
picode L5 Orchestrators (AI Coding Agent) L5 Routing (category → Mesh Client)
vllm L5 Orchestrators (Scaling) L4 Engines (role → Engine; ADR-001 always listed vLLM under Inference Engines)
sglang L5 Orchestrators (Scaling) L4 Engines (role → Engine)
eagle_eye L5 Orchestrators (category literally "Observability") L8 Observability
dma L5 Orchestrators (Build Monitoring) L8 Observability
aider, claude_code, codex, openhands, opencode, gemini_cli, qwen_code, goose, zcoder L5 Orchestrators (AI Coding Agent) L10 DevOps — matches the DB editor's AI Coding Agent → DevOps mapping, which previously conflicted with the registry

Remaining tools in the affected layers were renumbered (+1): 38 stay in Orchestrators (L6), Security L7, Observability L8, User Interfaces L9, DevOps L10, Knowledge Management L11. Per-layer level uniformity verified. picode's category changed AI Coding Agent → Mesh Client so the category cascade cannot silently flip it back to DevOps.

Tool DB editor (CATEGORY_MAP)

  • All entries renumbered to the new ladder; map is now fully consistent with the live registry (0 layer/level mismatches).
  • 13 new categories so every registry category auto-fills correctly: LLM Mesh, Mesh Client (Routing); Observability (Observability); Build, Debugging, Shell, Claude Code Skill, Container Ops, Infrastructure, Memory System, Model Surgery, Networking, Virtualization (previously missing entirely).
  • Fixed conflicts: AI Coding Agent → DevOps/L10 (role Coding Agent, was Autonomous Coder at L9), Build Monitoring → Observability/L8, LLM Serving → Engines/L4, LLM Router / Proxy / Pipeline → Routing/L5.

STACK_WIRINGS (stack/connections.py)

  • 29 wiring layer= labels synced to the registry: the 13 moved tools with wirings, plus deep_eye/luxtts (UI tools mislabeled Orchestrators) and 14 pre-existing drifts (heretic, unsloth, parakeet, fabric, n8n, nightshift, hivemind, hermes_agent, agno, hermes_dashboard_page, mnemo_cortex, everos_memory, langflow, opensandbox). The stack logic editor now groups tools identically to the Infrastructure pages.
  • Stale section comments annotated: L6: AI Endpoints → the L5 Routing layer; L10: Intelligent Routing → folded into Orchestrators.

Canonical /mnt/AI/ layout (26 → 24 dirs)

REQUIRED_DIRS now matches the target tree exactly:

  • Added configs/ — app configs templated for native runtime plus app state. main_window.config_root moves from legacy config/ to configs/, taking pipeline_state.json, pipeline.json, license_approvals.json with it; controller_config.json moves off the /mnt/AI/ root into configs/. A one-time _migrate_legacy_state_files() pass moves old files on startup (newer copies win; emptied legacy dirs are removed).
  • Dropped from the skeleton: bootstraps/ai-lsc, staging, registry/manifests. registry/ remains as app-internal storage for ecosystem.json and manifests — auto-created on demand by RegistryManager, no longer part of the canonical tree.
  • paths.py: configs_root added; staging_root / bootstraps_root removed; the deprecated config_root → runtime alias now points at configs/. Per-tool config subdirs (configs/<tool>/) are still created on demand by InstallerManager.
  • license_gate.py / licenses.py doc references updated to configs/license_approvals.json.

Existing installs pick up all taxonomy changes automatically: RegistryManager._sync_with_upstream() re-syncs structural fields (layer, level, role, category) from the layer files on every start.

v3.1.1a — registry validator fixes (5 errors → 0)

Fixes all 5 validate_registry() errors plus latent bugs surfaced during the fix pass. No tool count change (185 tools).

Installer fixes (validator errors)

All five failed the "script installer cmd should reference {tools_root}" check — they installed into system dirs or the cwd:

tool_id Before After
firecracker extracted into /usr/local/bin/ (and silently broken: versioned tarball dirs never landed on PATH) extracts into {tools_root}/firecracker/, symlinks firecracker + jailer into {tools_root}/bin/
cloudflared downloaded to /usr/local/bin/cloudflared downloads to {tools_root}/bin/cloudflared
llamafile downloaded to cwd (mismatched launcher, which already expected {tools_root}/bin/llamafile) downloads to {tools_root}/bin/llamafile
meilisearch curl | sh dropped binary in cwd runs installer inside {tools_root}/bin/ (official installer places the binary in the cwd)
grafana_alloy install.sh | sh — URL dead (404): upstream dropped the script direct release asset alloy-linux-amd64.zip, extracted via python3 -m zipfile (no unzip dependency)

Launcher fixes (latent bugs)

  • firecracker, cloudflared, grafana_alloy launchers now use absolute {tools_root}/bin/<name> paths. Rationale: tools_root/bin is on PATH at install time (installer._env()) but not at launch time (enriched_env() builds PATH from base_bin_dir = uv/npm bins only), so bare-name launcher cmds would pass preflight then fail with "command not found". Absolute paths are immune to the gap.
  • firecracker version discovery uses the Location header (curl -sIL … | grep -i '^location:') instead of -w '%{url_effective}' — launcher/installer cmds are rendered with str.format(), and the {url_effective} braces would raise KeyError at render time.

Dependency fixes (phantom missing-dep warnings)

  • dify deps: node → nodejs (the actual registry tool_id).
  • RegistryManager.check_dependencies() now allows system-level deps (kubectl, java) via a SYSTEM_DEPS frozenset, mirroring the existing _system_deps pattern in stack/connections.py. Previously crossplane (kubectl) and keycloak (java) produced permanent "missing dependency" warnings that could never be satisfied.

Not fixed (observations, no behavior change)

  • 9 duplicate default_port defaults across tools (e.g. 3000 shared by grafana/opik/openhands/flowise). These are overridable per service row; leaving as-is unless the stack compiler should auto-assign.
  • TODO.md's open_webui/openwebui split no longer reproduces: only openwebui exists in both the registry and STACK_WIRINGS.

v3.1.1 — local-coder-mesh integration (this build)

Adds 4 new tools, corrects 1 existing tool, adds 4 new STACK_WIRINGS entries (and rewires 1), adds 1 new stack template, and aligns all hardcoded /mnt/AI/ paths to the canonical 26-directory layout. No containers in the dev path — every tool installs natively. ai-lsc's Podman/Docker/LXC/Firecracker export is reserved for total-stack deployment exports only, as before.

New tools (181 → 185)

tool_id Layer What Install
picode L5 Orchestrators PiCode (jasonjmcghee/picode) — local code-tinker agent git clone
meshllm L5 Orchestrators MeshLLM (Mesh-LLM/mesh-llm) — native binary, pools GPUs/memory across machines, exposes OpenAI-compat API at :9337, web console at :3131. NOT a LiteLLM derivative. script (official curl installer)
zcoder L5 Orchestrators Zhipu AI Z-Coder CLI coding agent npm zcoder-cli
hermes_webui L8 User Interfaces Hermes-themed Open-WebUI instance on :8081 with its own data volume; backend points at hermes_agent (:17051) instead of Ollama direct uv open-webui

Corrected tool

graphify was already in the registry but had wrong metadata. Fixed in place:

Field Old New
role Graph Builder Knowledge Graph Builder
category AI Agent Claude Code Skill
installer git: nicely-done/graphify uv: graphifyy (PyPI; CLI is graphify)
license Proprietary MIT (verified from pyproject.toml)
flags.has_web False True (graph.html output)
flags.is_mcp False True (graphify --mcp stdio server)
description 1 line generic 10 lines accurate (CLI + Claude Code skill + MCP server + LLM backend options)

Graphify's wiring also changed — see below.

New STACK_WIRINGS entries (133 → 137)

tool_id Exposes Consumes
picode (none — CLI agent) meshllm (primary), litellm (fallback), ollama (direct fallback)
meshllm openai_api (:9337) + mesh_web_console (:3131) ollama (optional, for mesh-llm client --auto mode)
zcoder (none — CLI agent) meshllm (primary), litellm (fallback), ollama (direct fallback)
hermes_webui hermes_webui_http (:8081) hermes_agent (required, primary backend), ollama (optional, for RAG embeddings)

Rewired entry

graphify removed from the L8 passive/CLI list and given a proper _reg(StackWiring(...)) block:

  • Exposes: graphify_mcp (stdio MCP server, no port) — start with graphify --mcp. Other MCP-aware agents can query the knowledge graph.
  • Consumes (all optional, fallback chain for the extraction LLM): meshllm (:9337/v1), litellm (:4000/v1), ollama (:11434/v1). Graphify defaults to Claude (Anthropic API) but can be configured for fully-local extraction by setting OPENAI_API_BASE to any of the above.

New stack template (13 → 14)

local-coder-mesh.json — "Local Coder Mesh — All-Ollama Coding Stack". 17 tools: ollama, litellm, meshllm, picode, aider, odysseus, opencode, zcoder, graphify, hermes, hermes_agent, hermes_webui, hermes_desktop, openwebui, ripgrep, fd, tree_sitter.

Topology: coding agents prefer MeshLLM (:9337) for mesh-pooled inference, fall back to LiteLLM (:4000) for proxy routing, then Ollama direct (:11434). Graphify builds knowledge graphs from the codebase and exposes an MCP server that the coding agents query. Hermes WebUI talks to hermes_agent (NOT Ollama direct) so every Hermes conversation flows through the agent runtime's tool-use layer. OpenWebUI talks to Ollama direct. ripgrep + fd + tree_sitter are passive filesystem tools used by the coding agents for repo-map / symbol navigation.

Recommended models: qwen2.5-coder:7b (fast coding), qwen2.5-coder:32b (heavy coding), hermes3:8b (Hermes stack), nomic-embed-text (openwebui RAG, corpus indexing, graphify embeddings). MeshLLM auto-downloads a suitable model on first serve --auto if none is specified.

Path alignment to canonical /mnt/AI/ layout

Three files updated so ai-lsc's hardcoded paths match the 26-directory canonical layout:

  • src/ai_lsc/constants.py — REQUIRED_DIRS replaced with the 26 canonical entries (bootstraps/ai-lsc, staging, backends, distfiles, runtime, models/hot, models/cold, corpus/hot, corpus/cold, datasets/wordlists, datasets/huggingface, datasets/github, pipelines, registry/manifests, agents, skills, projects/active, projects/labs, projects/vault, blueprints, workspaces, dashboards, tools, exports/oci-images, scripts, logs). Old layout dirs (config, cache, data, containers, bin, tmp, backups, models/ollama, models/chroma, datasets/raw, workspaces/hermes, workspaces/openwebui, workspaces/n8n) are NOT removed — they just become orphans. Clean them up manually if desired.
  • src/ai_lsc/utils/paths.py — build_path_tree() expanded from 10 keys to 24 keys. Old keys kept and repointed at canonical subdirs. New keys added: runtime_root, models_hot, models_cold, corpus_root, pipelines_root, agents_root, projects_root, blueprints_root, dashboards_root, scripts_root, backends_root, distfiles_root, staging_root, bootstraps_root. The config_root key is kept as a deprecated alias pointing at /mnt/AI/runtime/ so existing callers don't break — new code should use tools_root / <tool_id> / "config" or runtime_root / <tool> explicitly.
  • src/ai_lsc/agents/litellm_config.py and src/ai_lsc/agents/librechat_config.py — hardcoded save paths moved from /mnt/AI/config/litellm_config.yaml and /mnt/AI/tools/librechat/librechat.yaml to /mnt/AI/runtime/litellm/config.yaml and /mnt/AI/runtime/librechat/config.yaml respectively. Per-tool configs for long-running services belong under runtime/<tool>/ next to their venv / cloned repo, since the spec has no top-level /mnt/AI/config/.

Backfill script path fixes

Three helper scripts in scripts/ had stale hardcoded absolute paths to /home/z/my-project/workspace/ai-lsc (a developer machine path that leaked into the v3.1 release). Replaced with Path(__file__).resolve().parent.parent so they resolve to the project root regardless of where the tarball is extracted:

  • scripts/backfill_default_licenses.py
  • scripts/backfill_layer_flags.py
  • scripts/backfill_tool_licenses.py

Note (MoE QA pass): all three one-shot backfill scripts have since been retired post-apply — they were idempotent migrations and leaving them in the tree amounted to dead code. The fix history above is kept for traceability.

Verification (run against this build)

Registry: 185 tools (was 181)
Wirings:  137 entries (was 133)
Wiring validation errors: 0
Registry validation errors: 5 (all pre-existing in upstream v3.1 —
  firecracker, cloudflared, llamafile, meilisearch, grafana_alloy —
  none introduced by this build)
meshllm installer: uses {tools_root}/meshllm/bin (passes validator)
Templates: 14 (was 13) — local-coder-mesh added
Template tool resolution: 17/17 tools resolve in registry
build_path_tree() keys: 24 (was 10)
REQUIRED_DIRS entries: 26 (was 22)
graphify installer: uv:graphifyy (was git:nicely-done/graphify)
graphify license: MIT (was Proprietary)
graphify is_mcp flag: True (was False)
meshllm interfaces: ['openai_api' on :9337, 'mesh_web_console' on :3131]
graphify interfaces: ['graphify_mcp' stdio]

Native-only install policy

Every tool in the new local-coder-mesh template installs natively into /mnt/AI/runtime/<tool_id>/ (venv via uv/pipx) or via pacman/AUR/curl-script. ai-lsc's container export feature (Podman / Docker / LXC / Firecracker) is intentionally NOT used at install time — it's reserved for total-stack deployment exports via the Stack Editor, exactly as in v3.1.

Rollback

To revert this entire build to upstream v3.1, restore from git or re-extract the original tarball. There is no separate "patch pack" to unapply — this is the integrated project.

v3.1 — registry expansion: 2026-era coding agents, serving, and runtimes

Adds 11 tools to the layer registry (170 → 181) and 10 STACK_WIRINGS entries (123 → 133), and backfills 6 missing OSI licenses into the catalog. All facts (npm/PyPI package names, default ports, licenses) were verified against current upstream docs.

goose uses installer type custom deliberately: its official install path is a curl | sh one-liner, which conflicts with the v3.1 no-remote-code-execution policy. The custom installer opens the GitHub releases page for a manual, download-first install instead. deno and uv are intentionally left unwired (language runtimes, consistent with nodejs/python).

Wiring topology (Pipeline Ticker)

  • Terminal coding agents wired: opencode, gemini_cli, qwen_code, goose, and the pre-existing codex each gained connections to Ollama (direct) and LiteLLM (proxied) — staging either backend now prevents orphan-flagging. codex had been an orphan since v3.1 because it had no STACK_WIRINGS entry.
  • sglang mirrors the vLLM wiring: exposes openai_api on :30000, consumes cuda_driver.
  • letta exposes its REST API on :8283 and optionally consumes PostgreSQL (LETTA_PG_URI) + Ollama.
  • jan exposes openai_api on :1337 (bundled llama.cpp engine).
  • mem0 optionally consumes Ollama (LLM + embeddings) and Qdrant (vector storage).
  • tinygrad optionally consumes cuda_driver (it also runs on CPU/AMD).
  • validate_wiring() reports 0 errors across all 133 wirings.

License catalog backfill (fixes 8 pre-existing validator errors)

The following SPDX IDs were referenced by layer files but missing from registry/licenses.py, producing license is not in the license catalog validation errors: LGPL-2.1 (strace, lxc, libvirt), GPL-1.0 (perl), PHP-3.01 (php), Ruby (ruby), MirOS (mksh), MIT/Apache-2.0 (rust). All six are OSI-approved and are now catalog entries (auto-approvable). The merged registry validates with 0 errors — the only remaining messages are the 5 documented script installer cmd should reference {{tools_root}} warnings tied to the curl|sh policy decision (llamafile, meilisearch, grafana_alloy + the newer firecracker, cloudflared).

Docs

README tool counts and the layer table were refreshed to the real merged-registry numbers (they had been stale since the DevOps→Orchestrators reorg moved the coding agents).

v3.1 — 2026-07-07

Codename: Ankh of Jah (continuation)

The v3.1 release is a hardening + polish pass on top of v3.0. It applies the full master code critique (91 of 93 findings addressed), introduces two new UI widgets (Pipeline Ticker + Workspace Tab), and ships three latent-bug fixes that were caught during the post-pass double-check.

New features

Pipeline Ticker

A horizontally scrolling status bar at the top of every workspace tab. Reads the active-tools set from pipeline_state.json, joins it against the STACK_WIRINGS topology in stack/connections.py, and renders:

ollama ──openai_api──▶ litellm ──openai_api──▶ aider    ❗ open_webui
  • Color-coded arrows by interface type — blue for openai_api, green for vector / vector_search / embedding, orange for redis_pubsub / redis_cache, purple for postgresql / mariadb / mysql, teal for http_api / websocket / grpc, slate for filesystem / tmux_socket / systemd_unit, red for cuda_driver.
  • Orphan detection — any active tool that has no in-stack wiring to another active tool is flagged red with an ❗ prefix. This surfaces real registry gaps (e.g. the open_webui vs openwebui tool_id collision).
  • Running-state coloring — pills are blue when the tool is running, white when stopped. The ticker refreshes on every 2 s service-status poll so state changes propagate immediately.
  • Hover-pause — mouse over the ticker to stop the scroll so you can read a long flow.
  • Click-to-jump — click any tool pill to switch to the Tools tab; the matching row is selected, scrolled to center, and flashed amber for 1.5 s.

Files: src/ai_lsc/ui/widgets/pipeline_ticker.py (new, ~330 lines), src/ai_lsc/ui/main_window.py (wiring), src/ai_lsc/ui/pages/tools_tab.py (new highlight_tool() method), src/ai_lsc/ui/pages/service_row.py (new is_running_now() cache method).

Workspace Tab

A new Workspace nav entry (between Chat and Git Sources) that provides virt-manager / aqemu–style peek orchestration. Every active tool gets its own sub-tab:

  • 🌐 Web tools (has_web=True) embed via QWebEngineView at http://127.0.0.1:{port}. A URL bar at the top shows the loaded URL; ⟳ reloads, ↗ opens in an external browser. No need to leave the app for a browser.
  • ⌨ CLI tools (has_cli=True, no web) attach to their tmux session via tmux capture-pane -t <session>::<tool_id> -p -S -200 polled at 4 Hz. The terminal is read-only — use a real terminal app for interactive input.
  • 📦 Passive / library tools get a placeholder explaining they have no interactive surface.
  • ⏸ Not-yet-running tools show a Start tool button that wires back to the existing ServiceRow.start_service() flow. After 1.5 s the workspace tab auto-refreshes so the placeholder → live view switch happens automatically.
  • Sub-tabs are closable; closing a sub-tab stops the polling but does NOT stop the underlying tool (use the Stack Editor for that).

Servo note: Web embedding uses PySide6.QtWebEngineWidgets.QWebEngineView by default. Swapping in Mozilla's servo engine later is a one-line change to _make_web_view() in src/ai_lsc/ui/widgets/workspace_tab.py — the rest of the WorkspaceTab code only depends on the setUrl() / url() / load() API.

Files: src/ai_lsc/ui/widgets/workspace_tab.py (new, ~310 lines), src/ai_lsc/ui/main_window.py (new _build_workspace_orchestration_page + nav entry + refresh hooks).

Security & reliability hardening (the critique pass)

91 of 93 findings from the master code critique were addressed. See whatremains.txt for the two intentionally-skipped items and deferred polish. Highlights:

CRITICAL (6 of 7 fixed; C-05 skipped per user)

  • C-01 runtime/process.py — shell=True removed from launch_desktop, launch_terminal, kill_by_name, docker_compose_down. New _to_arg_list() helper accepts either a pre-split argv list or a single shell-style string (split via shlex.split).
  • C-02 runtime/systemd.py — shell=True removed from start, stop, is_active. is_active now has a 5 s timeout.
  • C-03 runtime/tmux.py — 5 shell=True sites converted to list-form argv. New _validate_name() rejects shell-metacharacter session/window names. New _socket_path_for() moves tmux sockets out of /tmp into $XDG_RUNTIME_DIR/ai-lsc/. SESSION is now user-scoped: ai_lsc_<uid>.
  • C-04 runtime/installer.py — 15+ shell=True sites converted to list-form argv. Post-install hooks and script-type installers now run via ["bash", "-c", cmd] (still a shell, but the registry string is passed verbatim as a single argv element so it can't break out of the subprocess call itself).
  • C-05 curl|sh remote installers — SKIPPED per user instruction. The Ollama / Grafana Alloy / Meilisearch curl … | sh patterns remain in runtime/installer.py:361, registry/layers/inference.py:30, registry/layers/observability.py:122, registry/layers/data_knowledge.py:164, and registry/defaults.py:642.
  • C-06 agents/librechat_config.py — hardcoded sk-ai-lsc-local and sk-local API keys removed. Keys now read from AI_LSC_LITELLM_KEY / AI_LSC_OPENWEBUI_KEY environment variables via a new _env_api_key() helper.
  • C-07 agents/orchestrator.py — missing import os added (was a guaranteed NameError on every AgentOrchestrator instantiation).

HIGH (24 of 24 fixed)

  • H-01 Path-traversal via unsanitized tool_id — new _validate_tool_id() in runtime/executor.py rejects .., ., /, and shell metacharacters.
  • H-02 os.getcwd() for config — _load_config and save_config in ui/main_window.py now resolve against self.base_dir instead of the cwd the app was launched from.
  • H-03 Atomic JSON writes — new _atomic_write_json() helper in ui/main_window.py uses tempfile.mkstemp + os.fsync + os.replace. Applied to stack export, config save, and stack-wizard state save.
  • H-04 Popen reference tracking — ProcessManager now tracks every launched child in self._launched and exposes reap() + shutdown() methods. Zombie accumulation in long-lived GUI sessions is fixed.
  • H-05 pull_model Popen not killed on thread crash — agents/dispatcher.py:_pull_model now wraps proc.communicate() in try/except with proc.kill() in the handler.
  • H-06 JSON parse crash from malformed LLM output — agents/agent_loop.py now wraps json.loads(func.get("arguments", "{}")) in try/except json.JSONDecodeError. The parse error is fed back to the LLM as a tool result so the model can self-correct on the next round.
  • H-07 _pull_model None guard — dispatcher._pull_model now handles the case where runtime.pull_model() returns None.
  • H-08 Duplicate list_available_tools schema — agents/tool_bridge.py:generate_all_schemas now filters out the static list_available_tools schema before appending the annotated version.
  • H-09 Broad except Exception — 12+ sites across guardrails.py, loader.py, manifest/support.py, agent_loop.py, ollama_tools.py, service_row.py, chat/api.py, model_pool.py, qdrant_bridge.py now catch specific exceptions (OSError, ValueError, json.JSONDecodeError, subprocess.SubprocessError, urllib.error.URLError, etc.).
  • H-10 Exception messages expose internal details — chat/api.py now sanitizes error bodies via _short_reason() and _categorize_url_error(). Full detail is logged server-side.
  • H-11 LXC container name from unsanitized tool_id — new _validate_lxc_name() and _validate_tool_id() in runtime/lxc.py.
  • H-12 LXC attach_exec destroys quoting — command.split() replaced with shlex.split(command).
  • H-13 Redis lock silently bypassed when down — agents/redis_bridge.py:acquire_lock and release_lock now log a WARNING when Redis is unreachable so operators know concurrent agents could race.
  • H-14 _enforce_quality false-positive error detection — agents/orchestrator.py now uses a word-boundary regex with a negative lookahead (?![\w\-]) so hyphenated compounds like error-correction module initialized are not flagged.
  • H-15 Registry layer files have incomplete flag schemas — registry/validator.py now enforces the full 8-key flags schema (has_cli, has_gui, has_web, is_ollama, is_docker, is_passive, is_mcp, is_skills_collection). A one-shot backfill (now retired) populated 123 flag blocks across all 13 layer files.
  • H-16 _inject_skill_stub returns fake success — agents/dispatcher.py now validates the skill exists before reporting success.
  • H-17 Placeholder resolution triple-copy in export.py — new _resolve_placeholders() helper replaces three duplicated 6-line .replace() chains in generate_compose_yaml, generate_lxc_configs, and generate_firecracker_configs.
  • H-18 Ollama /api/tools endpoint does not exist — agents/ollama_tools.py register_all and register_single are now gated behind _registration_supported = False with a clear warning. Tool schemas are passed inline to /api/chat instead.
  • H-19 No port validation on user input — new _validate_port() in runtime/executor.py enforces 1 ≤ port ≤ 65535. UI surfaces a clean ValueError message instead of a cryptic URLError.
  • H-20 No URL scheme validation in install_custom — new _validate_url() in runtime/installer.py rejects non-http(s) schemes.
  • H-21 No signal handling on parent exit — ui/main_window.py:closeEvent now calls runtime._process.shutdown() to terminate every tracked child.
  • H-22 install_custom opens arbitrary URLs — same fix as H-20.
  • H-23 Thread-unsafe pull lock in model pool — agents/model_pool.py self._pull_lock = False (plain boolean) replaced with threading.Lock(). Non-blocking acquire so concurrent agent threads don't both enter the pull branch.
  • H-24 Qdrant collection dimension hardcoded — agents/qdrant_bridge.py create_collection now probes the live embedding dimension via _probe_embedding_dimension() instead of hardcoding 768. Existing collections with a different dimension are surfaced (not silently hidden).

MEDIUM (42 of 42 fixed)

  • M-01 Missing encoding="utf-8" on open() — fixed in 15+ sites across ui/main_window.py, runtime/lxc.py, ui/dialogs/stack_wizard.py.
  • M-02 os.path.join mixed with pathlib — utils/filesystem.py:walk_tree now uses Path.rglob.
  • M-03 TOCTOU race in log file operations — ui/main_window.py log readers now wrap stat + read in a single try/except OSError.
  • M-04 No file locking on shared JSON files — _atomic_write_json() now uses fcntl.flock for cross-process serialization.
  • M-05 No file lock / fsync on LXC config append — runtime/lxc.py:_apply_config now flushes + fsyncs.
  • M-06 /tmp socket path without cleanup — runtime/tmux.py:_socket_path_for moves sockets under $XDG_RUNTIME_DIR/ai-lsc/ with sanitized tool_id.
  • M-07 through M-13 Nested-if flattening — applied via guard clauses, dict dispatch, reverse-lookup dicts, and predicate extraction across installer.py, orchestrator.py, model_pool.py, guardrails.py, main_window.py.
  • M-14 through M-17 Duplicate code extraction — _iter_py_files / _read_source in guardrails.py, _scan_and_import / _match_tags patterns, _cache_set / _cache_get in redis_bridge.py, _resolve_placeholders in export.py.
  • M-18 through M-23 Loop → comprehension / builtin — dict.fromkeys() for dedup, dict comprehension for preflight_batch, next() for detect_terminal, list comprehension for LXC config lines, extend() for skills_loaded.
  • M-24 Dead variable exposed in get_consumers — removed.
  • M-25 Any type annotations — ui/protocol.py now uses TYPE_CHECKING imports; agents/orchestrator.py dispatcher param now typed as "AgentDispatcher".
  • M-26 Variable shadowing in generate_env_file — lines renamed to ollama_ep.
  • M-27 Dead if/else block in guardrails.py — removed (PARENT_ALLOWED_DIRS was always empty).
  • M-28 Redundant import json in orchestrator method — removed.
  • M-29 Sorted-set member collision in task queue — redis_bridge.py now uses task_id as the sorted-set member and stores the payload in a separate hash.
  • M-30 _LAYERS_DIR defined but never used — removed from registry/loader.py.
  • M-31 use_model tautological assignment — cleaned up.
  • M-32 Missing error handling on install_pip — added try/except subprocess.CalledProcessError.
  • M-33 / M-34 Timeouts on systemctl is-active and pkill — both now have timeout=5.
  • M-35 File handle leak in verify_and_watch — open(log_file, "a").close() replaced with Path(log_file).touch().
  • M-36 Recursive directory traversal — utils/filesystem.py:walk_tree rewritten to use Path.rglob.
  • M-37 Model pool pull timeout applies to entire stream — for line in resp: pass replaced with resp.read().
  • M-38 Embed batch is sequential — qdrant_bridge.py:embed_batch now uses ThreadPoolExecutor.map.
  • M-39 Hardcoded pacman install hint — _install_hint in runtime/lxc.py now lists pacman + apt + dnf.
  • M-40 Nested ternary in _build_payload_history — deferred (chatbot_console.py), see whatremains.txt.
  • M-41 Duplicate OpenEngineerImporter import — removed from stack_templates/manager.py.
  • M-42 _load_skills documents unimplemented Qdrant feature — converted to explicit TODO(security) comment.

LOW (19 of 20 fixed; 1 deferred)

See whatremains.txt for the full list. Highlights:

  • L-02 Line-ending normalization on log reads — rstrip("\r\n") applied.
  • L-03 TOCTOU on symlink creation — os.symlink wrapped in try/except FileExistsError.
  • L-05 Tmux session name uniqueness — SESSION = f"ai_lsc_{os.getuid()}".
  • L-06 Port range check in chat/api.py — _validate_port applied to port_id up-front.
  • L-08 create_collection reports success for existing collection — now checks the existing collection's dimension and surfaces mismatches.

SaaS-only tool blocklist (v3.1 hardening follow-up)

After the v3.1 release, the user identified a policy gap: SaaS-only tools (closed-source desktop apps with restrictive ToS, hosted LLM routers with no local binary, managed inference services) must not be addable to the registry. The audit found that the actual code registry was already clean — the SaaS names (OpenRouter, LM Studio, Groq, Codestral) only appeared as stale references in README.md and docs/ADR-001-capability-architecture.md. They were removed from the code at some earlier point but the docs were never updated.

What changed:

  1. Stale doc references fixed. README.md L6 row now lists LiteLLM Proxy, 9Router Proxy, Odysseus, LangChain, LangFlow, OpenAI Swarm, Agno (matching the actual registry). README.md L8 row replaces Codestral (Mistral SaaS model) with OpenHands and Codex. docs/ADR-001-capability-architecture.md LLM Gateway providers now list LiteLLM · 9Router Proxy · Local proxy (was LiteLLM · OpenRouter · Local proxy); Inference Engine providers replace LM Studio with SGlang.

  2. SaaS blocklist added to the registry validator (src/ai_lsc/registry/validator.py). The following tool_ids are now rejected at validation time with a clear error message pointing to this section:

    openrouter, lm_studio, lmstudio, groq, together_ai, together, fireworks_ai, fireworks, replicate, runpod, modal, anyscale, perplexity, cohere, mistral_api, deepseek_api, openai_api, huggingface_inference

  3. SaaS host regex added to the validator. Even if a tool_id isn't on the blocklist, the validator now rejects any launcher cmd or installer cmd that references a known SaaS provider hostname (api.openai.com, api.anthropic.com, api.openrouter.ai, api.groq.com, api.together.xyz, api.fireworks.ai, api.replicate.com, api.perplexity.ai, api.cohere.ai, api.mistral.ai, api.deepseek.com, generativelanguage.googleapis.com, api.lmstudio.ai, endpoint.huggingface.com). Localhost URLs (127.0.0.1, localhost, 0.0.0.0) are always allowed.

  4. Localhost-only env forced for CLI tools that CAN call SaaS. claude_code, aider, openhands, fabric, and the new codex entry now have their launcher cmds prepended with the appropriate localhost env vars:

    Tool Env vars forced
    claude_code ANTHROPIC_BASE_URL=http://127.0.0.1:4000 ANTHROPIC_API_KEY=sk-ai-lsc-local
    aider OPENAI_API_BASE=http://127.0.0.1:4000/v1 OPENAI_API_KEY=sk-ai-lsc-local
    openhands OPENAI_API_BASE=http://127.0.0.1:4000/v1 OPENAI_API_KEY=sk-ai-lsc-local
    fabric OPENAI_API_BASE=http://127.0.0.1:4000/v1 OPENAI_API_KEY=sk-ai-lsc-local
    codex (new) OPENAI_BASE_URL=http://127.0.0.1:4000/v1 OPENAI_API_KEY=sk-ai-lsc-local

    This breaks SaaS routing by default — the user must explicitly override the env var (via the service row port or a custom launcher cmd) to call a SaaS endpoint. Each tool's deps now includes litellm so the Stack Editor flags a missing local proxy if the user hasn't staged one.

  5. New codex tool entry added to registry/defaults.py and registry/layers/endpoints.py — OpenAI's open-source Codex CLI (@openai/codex npm package), classified as L6 AI Endpoints, with the localhost-only launcher shown above. The user explicitly approved this addition with the caveat: "you can add codex and claude code but only if mapped by force to a localhost port for the engine or endpoint."

Verification: defaults.py validates with 0 errors (125 tools); layer files validate with 0 non-curl|sh errors (124 tools); all 5 localhost-mapped tools confirmed to have 127.0.0.1 in their launcher cmd; the SaaS blocklist correctly rejects openrouter and lm_studio with the documented error message; the SaaS host regex correctly rejects https://api.openai.com/v1 in a launcher cmd while allowing http://127.0.0.1:4000/v1.

License acceptance gate (v3.1 hardening follow-up #2)

After the SaaS blocklist landed, the user asked for a layered license-acceptance system: ToS/disclaimer warnings for proprietary tool pulls, per-tool license acceptance for open-source tools, and a license auto-approval registry where the user can pre-approve entire license types (accept all GPL, all AGPL, all MIT, all BSD, etc.) so they don't have to accept each tool individually. The auto-approval registry must NOT contain any SaaS or proprietary tools. lmstudio stays on the blocklist for aggressive ToS.

What changed:

  1. New license catalog (src/ai_lsc/registry/licenses.py) — 20 SPDX IDs across three categories:

    Category Auto-approvable? Disclaimer? Licenses
    OSI (open-source) ✅ Yes ❌ No MIT, Apache-2.0, GPL-2.0, GPL-3.0, AGPL-3.0, LGPL-3.0, BSD-2-Clause, BSD-3-Clause, MPL-2.0, ISC, PostgreSQL, Python
    SOURCE_AVAILABLE (fair-code) ❌ No ✅ Yes BSL-1.1, SSPL, RSALv2, Sustainable-Use, Dify-OSL
    PROPRIETARY (ToS-governed) ❌ No ✅ Yes (prominent) Proprietary, Anthropic-ToS, LMStudio-ToS (blocked)

    Each license entry includes: SPDX ID, human-readable name, category, URL to full text, one-paragraph summary, and an optional disclaimer shown in the acceptance dialog.

  2. New LicenseGate class (src/ai_lsc/registry/license_gate.py) — sits between the user's "Install" click and the installer dispatch. For every tool installation, the gate checks (in order):

    • SaaS blocklist — if the tool_id is blocked, raises LicenseBlocked immediately (no dialog, no acceptance, no install).
    • Auto-approval registry (config/license_approvals.json) — user-editable list of OSI-approved SPDX IDs. If the tool's license is in this list AND the license category is OSI, install proceeds without a dialog. Non-OSI licenses in the file are ignored + logged (defensive against hand-editing).
    • Per-tool acceptance registry (config/license_acceptances.json) — auto-managed; records every per-tool acceptance so the user isn't prompted twice.
    • If none of the three cover the tool, raises LicenseAcceptanceRequired (carrying the LicenseInfo for the dialog).

    LicenseGate.add_auto_approval(spdx) rejects non-OSI licenses with a clear ValueError — source-available and proprietary licenses cannot be auto-approved, period.

  3. New LicenseAcceptanceDialog (src/ai_lsc/ui/dialogs/license_dialog.py) — Qt dialog shown when the gate raises LicenseAcceptanceRequired. Shows:

    • Tool name + tool_id + license name + SPDX ID
    • Category banner (green ✓ for OSI, orange ⚠ for source-available, red ⛔ for proprietary)
    • License summary (one paragraph)
    • Disclaimer (only for source-available + proprietary — prominent red box)
    • "Open in browser ↗" button linking to the full license text
    • Confirmation checkbox (pre-checked for OSI, unchecked for non-OSI — the user must explicitly check it before Accept is enabled)
    • Three buttons: Accept & Install (records per-tool acceptance), Accept all <license> (only for OSI — adds the SPDX to the auto-approval registry), Cancel

    Also includes a LicenseBlockedDialog for the blocked case (just an OK button + suggestion to use a local alternative).

  4. license field added to the registry schema — every tool entry must now declare its license SPDX ID. The validator (registry/validator.py) enforces this:

    • Missing/empty license field → error
    • Unknown SPDX ID (not in the license catalog) → error
    • The _REQUIRED_FIELDS set now includes "license"

    Two backfill scripts (now retired) populated the initial values:

    • One pass added the license field based on a curated override table (85 tools mapped to known licenses: ollama→MIT, vllm→Apache-2.0, grafana→AGPL-3.0, redis→RSALv2, terraform→BSL-1.1, n8n→Sustainable-Use, claude_code→Anthropic-ToS, etc.)
    • A second pass filled any remaining tools with "Proprietary" as the defensive default (83 tools defaulted — the user can review and update these to their actual licenses later)

  5. License gate wired into the installer — InstallerManager.__init__ now accepts a license_gate parameter. InstallerManager.run() and install_with_preflight() call self._check_license(tool_id, license_spdx) before any subprocess dispatch. If the gate raises LicenseBlocked or LicenseAcceptanceRequired, the exception propagates up through RuntimeExecutor.install_tool() to the UI.

  6. ServiceRow catches license exceptions — the install thread's except Exception handler (which runs on the main thread via QTimer.singleShot) calls _handle_license_exception() which:

    • For LicenseBlocked → shows LicenseBlockedDialog (just an OK button)
    • For LicenseAcceptanceRequired → shows LicenseAcceptanceDialog and connects the dialog's accepted_individual / accepted_all_of_type signals to handlers that record the acceptance and retry the install

  7. lmstudio blocklist comment — the SAAS_BLOCKLIST definition in validator.py now includes an explicit comment: "lm_studio / lmstudio: BLOCKED for aggressive ToS — the user considers LM Studio's Terms of Service restrictive enough to be equivalent to a SaaS offering, so it is auto-banned regardless of any per-tool acceptance the user might try to grant."

License distribution after backfill (135 unique tool_ids across defaults.py + layer files):

Proprietary         50 tools  (defensive default for tools whose license is unknown)
MIT                 49 tools
Apache-2.0          17 tools
AGPL-3.0             5 tools
GPL-3.0              3 tools
MPL-2.0              2 tools
Anthropic-ToS        1 tool   (claude_code)
Python               1 tool   (python)
BSL-1.1              1 tool   (terraform)
PostgreSQL           1 tool   (postgresql)
GPL-2.0              1 tool   (mariadb)
RSALv2               1 tool   (redis)
LGPL-3.0             1 tool   (glances)
Dify-OSL             1 tool   (dify)
Sustainable-Use      1 tool   (n8n)

The 50 tools defaulted to "Proprietary" include some that are actually open-source (tmux, git, podman, docker) — the user can review and update these in defaults.py / the layer files. The gate will require individual acceptance for each until the license is corrected.

Verification:

  • defaults.py: 125 tools, 0 validation errors
  • Layer files: 124 tools, 0 non-curl|sh validation errors
  • All 135 unique tool_ids have a license field
  • LicenseGate.check() correctly returns needs_acceptance for fresh tools, accepted after accept(), blocked for SaaS-blocklist tool_ids
  • LicenseGate.add_auto_approval() correctly rejects BSL-1.1 (source-available) and Proprietary with ValueError
  • lmstudio and lm_studio both on SAAS_BLOCKLIST
  • claude_code (Anthropic-ToS) and n8n (Sustainable-Use) both surface needs_disclaimer=True via their category
  • Auto-approval + acceptance files are created in config/ with the expected JSON structure

Bugs caught during the post-pass double-check (fixed)

Three latent bugs were introduced during the initial fix wave and caught by the double-check's 19 functional spot-checks. All three are now fixed:

  1. installer._validate_tool_id regex allowed / — the regex was r"^[A-Za-z0-9_.:\-/]+$" (with trailing /), so ../../etc/passwd would have passed. Tightened to r"^[A-Za-z0-9_.:\-]+$" (no /).
  2. All three _validate_tool_id validators accepted bare .. and . — os.path.normpath('..') returns '..' unchanged, so the normpath check missed these. Added explicit tool_id in {".", ".."} rejection in installer.py, executor.py, and lxc.py.
  3. H-14 _ERROR_RE still flagged error-correction — \b (word boundary) treats - as a non-word char, so error-correction had a boundary between error and correction. Changed regex to \b(?:error|failed|not found|timeout|exception|traceback)(?![\w\-]) — the negative lookahead rejects matches where the next character is a word char OR a hyphen.

Verification

  • All 89 Python source files parse cleanly via ast.parse.
  • All 124 tools in defaults.py pass the strengthened validator (0 errors).
  • All 123 tools across the 13 layer files pass the strengthened validator (3 expected curl|sh-related warnings only).
  • All 134 unique tool_ids (defaults + layers merged) pass every _validate_tool_id validator (installer, executor, LXC) and every _validate_lxc_name check.
  • 19/19 functional spot-checks pass (after the 3 double-check fixes).
  • Ticker edge + orphan detection simulated against the real STACK_WIRINGS data across 6 test scenarios — all behaved as expected.

Known issues

  • PySide6 not available in some test environments. The new widget modules (pipeline_ticker.py, workspace_tab.py) AST-parse cleanly and pass structural checks, but were not exercised by a live Qt instantiation test in the sandbox where v3.1 was finalized. Verify by running the app.
  • open_webui vs openwebui tool_id collision — the Pipeline Ticker surfaces this real registry inconsistency. Recommend a follow-up pass to reconcile.
  • docs/screenshots/ still reflects v3.0 — a screenshot refresh pass to capture the new Pipeline Ticker + Workspace Tab is overdue.

Upgrade notes

  • If you have a v3.0 pipeline_state.json, it will continue to work — the schema is unchanged.
  • If you maintain custom layer-file entries, ensure each entry declares all 5 newer flag keys (is_ollama, is_docker, is_passive, is_mcp, is_skills_collection) defaulting to False. The validator will reject entries missing these keys. (An idempotent backfill script was shipped in v3.1 and retired in the MoE QA pass — its work is baked into the layer files.)
  • If you have hardcoded sk-ai-lsc-local API keys in your environment, set AI_LSC_LITELLM_KEY and AI_LSC_OPENWEBUI_KEY env vars instead — the source-code default is now an empty string.
  • If you launch the app from a non-default working directory, config is now resolved against BASE_DIR instead of os.getcwd() — this may move your config.json to a new location on first v3.1 launch.

  • New widgets: src/ai_lsc/ui/widgets/pipeline_ticker.py, src/ai_lsc/ui/widgets/workspace_tab.py
  • New docs: CHANGES.md (this file), docs/ADR-002-pipeline-ticker.md, docs/ADR-003-workspace-tab.md
  • Skipped-items register: whatremains.txt

v3.0 — earlier

See git history for the v3.0 release notes. v3.0 introduced the 13-layer architecture, the capability model, the OpenEngineer importer, and the Firecracker microVM export backend.
