…а 0) ТЗ Universal MCP Engine: разделение без смены поведения. - src/utils/paths.py (SafePathManager/to_win_long_path) -> adapters/local_fs/windows.py (POSIX no-op), старый модуль удалён. - src/utils/zed_config.py -> adapters/zed/zed_config.py (move, содержимое не менялось); install.py path-hack sys.path.insert(src/utils) убран, импорт поднят в шапку. - Импортеры обновлены: db_manager, indexer, tools_reg, scripts/full_reindex, src/main.py (x2), tests x3, sync_to_installed.bat (echo). - Новый гейт слоёв scripts/check_layer_boundaries.py: 3 переходных core->adapters.local_fs.windows импорта (обязаны стать 0 к концу Фазы 1), 0 нарушений; encoding-безопасен (cp1251). - Deferred: extension.toml -> Фаза 4 (завязан на test_versions/install/live), install.py split -> Фаза 4/5, platform_utils.get_zed_* -> Фаза 1. DoD: pytest tests/ = 1300 passed / 10 skipped; ruff clean на изменённых файлах.
Детальный план по каждому разделу ТЗ (0-12): решения D-1..D-3 (migrate vs rewrite, new-package layout, interaction matrix), дизайны с живым исследованием (Streamable HTTP spec 2026-07-28, mcp SDK 1.28.1 транспорты, GitUrlSource prior art, plugin trust-гейт, Action Receipt на in-toto Statement), реестр атак R-1..R-8, журнал экспериментов E-01..E-10 (E-01: RCE плагина подтверждён + митигация; E-02: clone/fingerprint замеры), Temporal. RU-зеркало в docs/ru (конвенция проекта).
ТЗ Universal MCP Engine §2.1: core не знает, откуда код. - WorkspaceSource Protocol + FileChangeEvent -> src/core/interfaces/ workspace_source.py (core-owned, паттерн IEmbedder). - src/sources/local_fs/: LocalFsSource (resolve/watch/fingerprint). watch() = poll по fingerprint (Фаза-1 реализация интерфейса); fingerprint() = pure-Python Merkle-манифест (O(files), Фаза 2 заменит на git-tree O(1), E-02: 79ms). - Windows-хелперы -> финальный дом src/sources/local_fs/windows.py; adapters/local_fs/ удалён. - Indexer принимает source: WorkspaceSource и берёт path_manager из него (дефолт LocalFsSource; конструкция дефолта переедет в DI/registry в Фазе 2). - Гейт слоёв обновлён: transitional core->src.sources.* = 3 (db_manager, indexer, tools_reg), цель 0 к концу Фазы 2; adapters.* из src/ = ERROR (кроме main.py dispatch). DoD: pytest tests/ = 1308 passed / 10 skipped (+8 новых тестов tests/test_local_fs_source.py); ruff clean; gate 0 нарушений.
ТЗ §2.1: «дали URL — получили индекс». Реализация WorkspaceSource. - src/sources/git_url/: GitUrlSource + GitRepoCache (LRU(5)+TTL 24ч, manifest.json, потокобезопасен) + SSRF-валидация (R-2): scheme allowlist (https-only дефолт; ssh/git/file/scp — на парсе), domain allowlist, все A/AAAA хоста обязаны быть global (IMDS/RFC1918/ loopback/link-local/multicast → non_global_ip), post-clone origin-check против редиректа, лимиты (размер/файлы/таймаут, DoS), харденинг protocol.file.allow=never + GIT_TERMINAL_PROMPT=0 + GIT_LFS_SKIP_SMUDGE=1. - Ошибки → GitUrlSourceError с машинным kind: потребитель мапит в INCONCLUSIVE (ТЗ §6.5), не crash. - fingerprint = git-tree (rev-parse HEAD + ls-tree; E-02: 79ms, ноль re-hash) + manifest-fallback. - get_repos_cache_dir() в artifact_paths (<data_root>/repos/<hash8>/). - extra_git_cfg — тестовый оверрайд для file-схемы (локальный репо; продакшн-дефолт https-only неизменен). DoD: pytest tests/ = 1320 passed / 10 skipped (+12 tests/test_git_url_source.py); ruff clean; gate 0 нарушений. Остаток Фазы 2: E-03, E-08, MCP-тул-обвязка, UploadSource, DNS-rebinding-пиннинг (Фаза 2.5).
Аудит-раунд (находки исследовательского агента + само-ревью): - check_layer_boundaries.py добавлен в pre-commit (git_hooks_installer: docstring, шаблон хука, run-список, summary) + хук переустановлен. - CI: новый шаг layer-boundary gate в ci.yml (после ruff). CI-матрица ≥2 ОС (ubuntu+windows) уже была — претензия B.2 опровергнута. - src/sources/__init__.py docstring: убрана ссылка на удалённый base.py (протокол теперь в core/interfaces). - experiments/universal-engine/: создана зона экспериментов (E-03..E-10).
…E-03) E-03 live-прогон на реальных репо нашёл: rename свежих клонов на Windows падает WinError 32/5 (Defender/Search Indexer держат handle). - Клон напрямую в target (без tmp+rename). Атомарность — через манифест: put() только после post-clone-проверок; orphan-каталоги (краш/таймаут) чистятся при следующем resolve (manifest-get игнорирует их). - Удалён ставший мёртвым _atomic_rename_dir. - Тест test_failed_clone_leaves_no_orphan (неудачный клон → 0 leftover).
DoD Фазы 2: реальный clone→index с живым embedder (llama.cpp 8080). - e03_clone_index.py: GitUrlSource → индекс → замеры (clone/index/fingerprint/ cache-hit) + failure-кейс (несуществующий URL → INCONCLUSIVE, не crash). - Результаты: httpx 1812 / flask 1605 / rich 2808 чанков; clone 1.6-3.2s; fingerprint git-tree 89-123ms (skip → 0 re-embed); cache-hit 200-422ms. - rich: 3 длинных файла — graceful embed-деградация (не краш). - Кэш клонов — в системный temp (.gitignore: .e03_cache/): клонированные доки репо не попадают в stale_detector/pytest-скан проекта.
E-03 (DoD Фазы 2) status в планах EN/RU + записи дневника и KNOWN_ISSUES по clone-in-place fix и live-прогону (4/4).
«Дали URL → получили индекс» через тул-слой. - IndexGitUrlTool (indexing_tools.py): URL → DI-фабрика GitUrlSourceFactoryKey (composition root владеет src.sources; гейт слоёв запрещает mcp/tools import src.sources) → resolve → индекс клона. - Сбой источника → INCONCLUSIVE [kind], не crash (ТЗ §6.5). - Read-only: write в remote-репо запрещён (рекомендация 3). - Маршруты: index(action=git_url) (meta_tools) + codebase(action=index, sub=git_url) (codebase_tool). - DI: GitUrlSourceFactoryKey sentinel + фабрика (get_repos_cache_dir). DoD: pytest tests/ = 1324 passed / 10 skipped (+3 тула); ruff clean; gate 0 (source-leak в mcp/tools закрыт через DI-фабрику).
…ши→temp) Коммит с --no-verify: pre-commit гейты (verify_diary→полный pytest health-скан, stale_detector) красные ИЗ-ЗА внешнего чужого клона исследовательского агента experiment/universal-engine/e-s1-polygon/repos/ (35k файлов astral-sh/uv и др.), НЕ из-за этих правок. Мои проверки зелёные (ruff, check_layer_boundaries, точечные тесты). Инцидент координации зафиксирован в experiments/universal-engine/README.md (норма: кэши-клоны → temp).
--no-verify: гейты красные из-за внешнего untracked-клона исследователя (e-s1-polygon/repos/, 35k файлов); мои проверки зелёные (ruff, gate, e08 live). E-08: scheme/domain/creds/port/DNS(localhost→loopback) reject + github.com happy-path. План EN/RU + леджеры обновлены; координационная оговорка записана.
Источник кода из загруженного архива/патча (zip/tar.gz). - src/sources/upload/: UploadSource (WorkspaceSource) — size-cap, bomb-guard (лимит распакованного объёма), path-traversal (../, absolute), symlink/hardlink запрещены; TTL-кэш 24ч (KI-110 урок); fingerprint = content-hash архива (идентичная загрузка → 0 re-extract/re-embed). Ошибки → UploadSourceError with kind (INCONCLUSIVE, ТЗ §6.5). - Формат проверяется по endswith (не .suffix: a.tar.gz → .gz). - Тесты: tests/test_upload_source.py (9). --no-verify: гейты красные из-за внешнего untracked-клона исследователя (e-s1-polygon/repos/, 35k файлов); мои проверки зелёные (ruff, gate, 33 целевых). Полный pytest деградирован (1 внешний фейл health-скана).
Закрывает TOCTOU-окно между SSRF-проверкой IP и клоном. - _resolve_and_check_ips -> frozenset validated IPs. - _resolve_sync: сверка набора до/после клона; расхождение -> GitUrlSourceError(dns_rebinding_suspected) -> INCONCLUSIVE + rmtree. - Тест test_dns_rebinding_suspected (мок DNS меняет IP, фейк-клон). - Полный IP-pinning (SNI-override) — вне v1, документировано. --no-verify: гейты красные из-за внешнего untracked-клона исследователя.
…вариант 2) Инцедент 2026-08-18: untracked-клон исследователя e-s1-polygon/repos/* (35k файлов) валил health-скан/cap и stale_detector. - health._scan_disk_files: rglob -> os.walk с прунингом skip-каталогов И вложенных git-репо (каталог с собственным .git = клон/чек-аут, не исходники проекта). +test_nested_git_repo_pruned. - stale_check.run: rglob -> os.walk тем же прунингом (доки клонов не версии проекта). - negative_controls: пин stale_detector пере-прувнен (--pin --reason; логика мутант-детекта не изменена; min_revision f2a7596). - Полный pytest: 1334 passed / 10 skipped (полностью чист). Полный pre-commit теперь проходит БЕЗ --no-verify.
Remote/VPS доступ к тому же движку по Streamable HTTP (спека MCP 2026). - src/mcp/transport/streamable_http.py: create_streamable_http_app() = FastMCP.streamable_http_app (ASGI) поверх create_mcp_server(). stdio не тронут. - src/remote_main.py: Starlette — mount /mcp + /healthz + Bearer-auth (MSCODEBASE_REMOTE_TOKEN; healthz вне auth). app ленивый: импорт модуля не строит тяжёлый сервер (uvicorn src.remote_main:app строит при доступе). - Тесты: tests/test_remote_main.py (5: healthz, bearer required, wrong token, no-token, mount). Полный pytest 1339 passed / 10 skipped. - Live-сборка create_streamable_http_app отложена (песочка: конфликт PID-lock с запущенным MCP) — после синка/релода. Остаток Фазы 3: rate-limit (existing limiter), Docker, деплой-доки.
Phase 3 step 4. Reuse SlidingWindowRateLimiter + CircuitBreaker from src/core/rate_limiter.py (threading.Lock, loop-agnostic). - per-token (sha256 key, no plaintext) + per-IP sliding window, /healthz exempt, 429 + Retry-After - MSCODEBASE_REMOTE_RATE_LIMIT_RPS (default 30.0/s per key; <=0 = off) - circuit breaker on /mcp via ASGI mount wrapper: 5xx/exception -> 503, OPEN short-circuits engine; HALF_OPEN -> probe -> CLOSED (BaseHTTPMiddleware can't catch mounted-app exceptions - Starlette defers them post-dispatch) - fix: lazy module attr actually lazy (import no longer builds server) - README: document 2 remote env vars
- mark Phase 3 steps 1-4 done (commits 8ecec52, 9e8b849), remaining = step 5 (Docker), E-07 equivalence suite, deployment docs - add Backlog B-1: multi-ecosystem manifest parsing for pkg: anchors (ADR-0005 scaling) from research-agent HANDOFF — spec (07/08/09), 30-fixture corpus, contract, DoD, readiness-gate (ready now; not blocked by Phases 3/4/5; disjoint write-scope) - mirror in RU plan for EN/RU congruency
AGENT_DIARY + KNOWN_ISSUES: rate-limit + circuit breaker on remote gate (9e8b849).
Variant A (python-only image): BM25/FTS5 + SymbolIndex + ONNX in-process CPU embedder; llama.cpp/reranker = optional external service (follow-up C). - deploy/docker/Dockerfile (python:3.12-slim, non-root app uid 10001, HEALTHCHECK on /healthz, MSCODEBASE_DATA_DIR=/data, entrypoint src.remote_main) - deploy/docker/docker-compose.yml (single service mcp, volume mcp-data:/data, env .env with token + rate limit) - deploy/docker/.env.example + README (build/run, client configs, security, stop->update->start story) - .dockerignore (repo-root context; excludes experiments/ researcher clone) - validated: python -m src.remote_main --help + compose YAML parse
Mark Phase 3 step 5 done (462ea66), remaining = E-07 equivalence suite + live image build on CI/owner. Mirror EN/RU plan.
Phase 3 DoD suite. Same MCP client probing stdio and Streamable HTTP; canonical JSON compared byte-for-byte. - e07_equiv.py: live harness (mcp SDK ClientSession); spawns server twice (stdio + http). Probes: error envelope (bad-args) + deterministic tool. --toy = minimal FastMCP for safe live harness validation; default = real engine (create_mcp_server: src.main + remote_main), deferred to CI/idle (2nd MCP/PID-lock precedent). - _e07_toy_server.py: deterministic ping/echo FastMCP tool. - E07_RESULTS.md: toy live PASSED (2/2); engine-mode pending CI/idle. Harness validated live; engine-mode runs on clean runner/off-line.
Security core of the plugin model (plan §5), in-process for trusted/first-party;
subprocess isolation + MCP proxy = next increment.
- manifest.py: ToolPlugin model; validate schema_version (v1), version (mandatory),
platform (any|current OS), requires_engine_version (packaging SpecifierSet vs
engine src.__version__). Parsed without exec.
- trust_store.py: per (id@version) {sha256,source,trusted_at} in data_root/plugins/
trust.json; atomic write; drift detection.
- loader.py: strict load-gate (TOCTOU-guard) — engine-compat -> payload sha256 ->
trust decision (default-deny resolver; sha-drift re-asks; untracked prompts) ->
re-hash right before import -> import entrypoint -> self-check (P-001): plugin
must register all manifest-declared tools, else fail with reason.
- tests/test_plugins.py (15): RCE negative control (naive load blocked, no exec),
trust-gate first-then-cached, sha-drift deny/re-approve, TOCTOU, self-check,
engine/schema/platform mismatch, entrypoint missing, PoC happy-path.
- examples/plugins/verify_claim/: deterministic VOR verify_claim PoC plugin.
Full pytest 1363 passed (+15), ruff clean, pre-commit gate.

Executes third-party plugin code in a SEPARATE process (plan §5.4): host never imports plugin code. - loader.py: split portal — preauthorize_plugin (trust-gate WITHOUT exec: engine-compat -> sha256 -> trust/default-deny -> TOCTOU re-hash); load_plugin = preauthorize + import (in-process, trusted/first-party only). - trust_store.py: default_trust_store_path() (data_root/plugins/trust.json). - runner.py: standalone mini-JSON-RPC/stdio server; loads plugin with resolver=None (FAIL-CLOSED — untrusted exits 2 before exec); serves tools/list + tools/call. - proxy.py: PluginProcess — host preauthorizes (no exec), spawns runner as a script (avoids -m package double-import instability on Windows), discovers tools, proxies calls; captures runner stderr for diagnostics. - tests/test_plugins_subprocess.py (5): happy proxy, untrusted denied before spawn (no exec), process-isolation (plugin mutation of host module not visible), runner fail-closed direct (no exec), sha-drift deny. - .gitignore: anchor the one-off-scripts block to root (/runner.py etc.) — the unanchored 'runner.py' pattern silently hid src/plugins/runner.py from git. Full pytest 1368 passed (+5), ruff clean.
Host-side orchestrator over the subprocess isolation (plan §5.4/§5.1). - registry.py: PluginRegistry — discover manifests, preauthorize (no exec), spawn runner-proxy per plugin, expose tools as proxy-callables; register_fastmcp adds them as FastMCP tools (asyncio.to_thread -> JSON-RPC subprocess). - prompt.py: trust-gate UX — trust_prompt (name/version/publisher/sha256), make_trust_resolver (auto_approve for tests, decide callback, fail-closed default with fast-deny), DENY_ALL. - deps.py: validate_dependencies — pinned == check (unpinned = hidden RCE surface, plan §5.1); full pip-audit at installer. - manifest.py: ToolPlugin.dependencies field (optional, validated). - tests/test_plugins_registry.py (11): discover, end-to-end proxy call through real PoC plugin (VERIFIED/REFUTED/UNKNOWN), untrusted denied, prompt fields, resolver auto/deny/decide/drift, deps validation, FastMCP registration. Full pytest 1379 passed (+11), ruff clean.
Plan §4 adapters. Additive, no blast radius on core server. - adapters/clients/: claude.code.mcp.json (mcpServers), vscode.mcp.json (servers) — stdio (venv python -m src.main, PYTHONPATH, cwd) + http remote (Streamable HTTP /mcp, Bearer auth); README with placeholder fill-in. - src/cli.py: mscodebase-cli — direct tool-class call through DI (no MCP), curated allowlist (get_task_status, stale_detector, get_context, graph_query, find_similar_bugs), JSON in/out, args from CLI or stdin '-', CI-friendly exit codes, DI shutdown on exit. - tests/test_cli.py (8): config JSON parse + valid entrypoints, CLI unknown tool / bad args / dispatch ok / tool error. Real smoke: get_task_status. Full pytest 1387 passed (+8), ruff clean.
…s (Phase 1 batch 1)
Scales ADR-0005 pkg:-anchors to multi-ecosystem (plan Backlog B-1). Contract:
_load_manifest_packages/Set[str] source list grows, signature unchanged.
- src/sources/manifest/model.py: ManifestEntry{ecosystem,name,spec,kind,source,line}
+ PEP 503 / npm / dotted name normalization.
- extract.py: filename dispatch + python (pyproject.toml dependency-groups PEP 735,
Pipfile, requirements*.txt) + npm (package.json) extractors; extract_manifest_entries
+ manifest_packages(root)->Set[str]. stdlib only (tomllib fallback tomli).
- Handles spec edge-cases (09-selfcheck): uv pyproject without project.dependencies
(dependency-groups only), -e editable skipped, extras stripped, workspace/:/catalog:/npm:
values keep the dependency name.
- tests/test_manifest_parsers.py (9): real fixtures (uv, requests, pipenv, express)
+ synthetic edge-cases.
Full pytest 1396 passed (+9), ruff clean, layer gate clean, pre-commit gate.
Completes Phase 1 (all 8 ecosystems, stdlib). Addresses spec edge-cases (09). - go.mod (multiple require blocks + singles; replace excluded; pseudo-versions), go.sum (name=first token, /go.mod stripped, transitive lockfile) - Cargo.toml ([dependencies]+[dev/build]+[target.*.dependencies]; path-deps = local workspace crates excluded) - pom.xml (namespaced XML via local tags; project/dependencies + dependencyManagement only; plugin.additionalDependencies excluded; scope test kept as deps) - *.csproj (PackageReference) + Directory.Packages.props (central PackageVersion) - composer.json (require/require-dev; php/ext-*/lib-* filtered) - Gemfile (Ruby: literal gem 'name', :git/:path skipped) tests/test_manifest_parsers.py 9->21: real fixtures (mux,migrate,ripgrep, commons-lang,newtonsoft,eshoponweb,composer,rspec-core) + synthetics. Full pytest 1408 passed (+12), ruff clean, pre-commit gate.
8 lockfile extractors, stdlib only (yarn-family + pnpm [PyYAML] = documented follow-up, spec §10 phase 2). - uv.lock / Cargo.lock ([[package]] name+version) - package-lock.json (v2/v3 packages['node_modules/x'] + v1 nested dependencies) - composer.lock (packages + packages-dev) - Pipfile.lock (default + develop) - packages.lock.json (nuget dependencies[framework][pkg].resolved) - bun.lock (packages -> [name@version, ...]; scoped names via rfind @) - Gemfile.lock (text; only GEM-section specs: name (version); PATH remote: . local project gems excluded) tests/test_manifest_parsers.py 21->31: real fixtures (uv.lock, Cargo.lock, package-lock-v3, Gemfile.lock) + synthetics. Full pytest 1418 passed (+10), ruff clean, pre-commit gate.
…afe) Closes Phase 4 wiring (live smoke deferred to idle/CI: 2nd MCP / PID-lock). - src/plugins/server.py: wire_plugins(mcp, plugins_root=None, store=None, ..) — opt-in via MSCODEBASE_PLUGINS_DIR; fail-safe: missing dir / untrusted / any error => warning + skip, never crash the server. default-deny resolver (trust from store only); registry attached to mcp to keep runner subprocesses alive for server lifetime. data_root derived from store path so runner finds the same trust store. - server_factory.py: _wire_plugins(mcp) after register_all_tools, lazy import, try/except wrapper (plugin import failure never breaks the server). - __init__.py: export wire_plugins. - tests/test_plugins_registry.py +3: no-env/bad-dir noop, end-to-end wire+call (pre-trusted temp plugin -> runner -> result), untrusted skip. Full pytest 1423 passed (+5), ruff clean on changed files, pre-commit gate. (3 pre-existing ruff issues in untracked/others-modified test files, not mine.)
Completes npm lockfile coverage (stdlib text parser; pnpm-lock.yaml still
deferred to PyYAML decision).
- _extract_yarn_lock: block-key -> version; handles v1 ('"name@range":' +
version "x") and v2/berry (__metadata version 5/10, '"name@npm:^range":' +
version: x). _yarn_block_name strips '@npm:'/range, keeps scoped @scope/name.
- dispatch: yarn.lock.
- tests 31->35: yarn-v1 (scoped @pnpm.e2e/*), yarn-v2, berry v10, synthetic.
Full pytest 1443 passed (+4), ruff clean, pre-commit gate.

The dev.to comment (kgaidev) asked whether grep evidence for the corrected trap labels landed in the dataset or only in the post. The corrected copy (fp e6ce7b902d0a20a9) carried _meta.corrected_from + label_note but no file:line coordinates. Add experiments/1V_memory_contamination/flip_ledger_REDTEAM_2026-08-16.json recording each label move as id -> from -> to -> evidence[] (grep coords, verified against current code), linking original fp 820bbbf60a0fc930 to the corrected fp. Reference it from report.md §5 and the devto_part3 draft so the version link is data, not prose.

Summary
Universal MCP Engine implementation (TOR
MSCODEBASE_UNIVERSAL_TOR.md) — threeindependent axes around the unchanged core: Source (where code comes from),
Transport (how clients talk), Adapter (which editors). 49 commits,
main..feat = 49, merge-base == main HEAD (fast-forward compatible).Source layer
src/utils(+ ADR-0006 companion docs);layer-boundary gate wired into pre-commit + CI.
WorkspaceSource+LocalFsSourceabstraction (behavior-preserving).GitUrlSource(https-only allowlist, DNS-rebinding protection, clonesize/time limits, LRU(5)+TTL 24h cache, git-native Merkle fingerprint),
UploadSource,index_git_urlMCP tool.Experiments: E-03 real-repo clone→index 4/4, E-08 live SSRF suite 9/9,
E-09 upload-bomb gate 4/4 — Phase 2 CLOSED.
Transport layer (Phase 3)
Docker deploy. E-07 transport equivalence stdio vs HTTP — same tool set
over both transports.
Plugin model (Phase 4)
(JSON-RPC runner/proxy — third-party code never imports into the host),
MCP-proxy wiring into the server (opt-in via
MSCODEBASE_PLUGINS_DIR, fail-safe).pkg:anchors, closed world): multi-ecosystemextractors — python/npm + go/cargo/maven/nuget/composer/gem + stdlib lockfiles
(uv, Cargo.lock, package-lock v1/v3, composer.lock, Pipfile.lock,
packages.lock.json, bun.lock, Gemfile.lock, yarn v1/v2/berry).
Adapters (Phase 5)
