chore(deps): resolve all 146 Dependabot security alerts

[ryanhayame]

Closes every open Dependabot alert on the repo: 146 / 146.

The alerts split across the only two manifests Dependabot scans:

manifest	alerts	how it's fixed
poetry.lock	62	version bumps
docs/package-lock.json	84	manifest deleted with the unused Docusaurus site

1. poetry.lock — 62 pip alerts

Bumped with poetry update --lock:

cryptography 46.0.3 → 50.0.0	gitpython 3.1.45 → 3.1.59	pillow 12.0.0 → 12.3.0	h2 4.3.0 → 4.4.1
urllib3 2.6.2 → 2.7.0	idna 3.11 → 3.18	pygments 2.19.2 → 2.21.0	torch 2.7.1 → 2.13.0
pytest 8.4.2 → 9.1.1	requests 2.32.5 → 2.34.2	setuptools 80.9.0 → 84.0.0	filelock 3.20.1 → 3.32.3

Two pyproject.toml changes were needed, both because the lock alone couldn't resolve them:

• pytest ^8.2.2 → ^9.0.3 — the advisory is only fixed in 9.0.3. The constraint was already stale; the dev venv was on 9.1.1.
• torch/torchvision floors — torchvision pins torch exactly (0.28.0 → torch==2.13.0) and its requires_python is !=3.14.1,>=3.10, which the project's ^3.10 includes. Without mirroring that marker, poetry can't satisfy the range and silently resolves backwards to torchvision 0.12.0 (a 2022 release, no wheels past cp310). CI caught exactly that. Now:

  torch       = ">=2.13.0"
  torchvision = { version = ">=0.28.0", python = "!=3.14.1,>=3.10" }

Note torch 2.13.0 moves to CUDA 13 wheels — the 14 nvidia-*-cu12 packages are replaced by cu13 equivalents plus cuda-toolkit/nvshmem. Expected, but worth knowing if anything downstream pins CUDA 12.

2. Removing the Docusaurus site — 84 npm alerts

docs/package-lock.json was the repo's only npm manifest, so deleting docs/ clears all 84 — including the two that no version bump could fix: image-size@2.0.2 (GHSA-5p2g-fcmc-qvqq, GHSA-w3rx-r6r6-pgpr), where 2.0.2 is the latest published release and both advisories are unpatched upstream.

The site is dead infrastructure:

• Live docs are Mintlify at docs.trainy.ai/pluto, built from Trainy-ai/konduktor's docs/pluto/ — 27 pages, actively maintained. The README already points there.
• docusaurus.config.js never got the mlop → pluto rename: title: 'MLOP', url: mlop-ai.github.io, organizationName: 'mlop-ai'.
• No gh-pages branch exists, and GitHub Pages is not enabled on the repo.
• docs.yml has never run once, and couldn't: it triggers only on push to the nonexistent gh-pages branch, then runs npm install && npm run build at the repo root, which has no package.json.
• No content change since Update Discord invite links to new community URL #68.

Nothing downstream breaks: Trainy-ai/konduktor references this repo's docs/ nowhere — no workflow, no code-search hit. No content is lost: 6 of the 12 deleted pages were heading-only stubs; the rest were MLOP-branded with dead links (demo.mlop.ai, pip install mlop[dev]). ~79 content lines total, all superseded by the Mintlify pages.

Also removed, all Docusaurus-only: .github/workflows/docs.yml, scripts/docs-init.sh, scripts/docs-pub.sh (the last deploys to git@github.com:mlop-ai/docs.git, the pre-rename org). Kept: docs/SYNC_PROCESS_V2_ARCHITECTURE.md → repo root; 440 lines of internal architecture docs that were never part of the site.

3. A latent console-upload bug that pytest 9 exposed

Bumping to pytest 9 turned two console tests red, and the cause turned out to be a real bug in pluto/log.py, not a test artifact.

setup_logger short-circuited on len(console.handlers) > 0, treating any handler on the console logger as proof pluto had already configured it. But setup_logger_file sets console.propagate = False, which forces anything capturing log records to attach at that logger rather than at the root — and pytest's logging plugin does exactly that from pytest 9 on.

Measured at the second init() in a process:

pytest	console.handlers	result
8.4.2	0	setup runs
9.1.1	2 × LogCaptureHandler	setup skipped

With setup skipped, no ConsoleHandler wrapper is installed, so nothing enqueues console lines — and the fd layer can't cover for it, because print() writes to sys.stdout, which under pytest capture never reaches fd 1. Zero console records, no error.

This outlives the tests. Any library attaching a handler to that logger — Jupyter tooling, an APM agent, a user's own logging setup before a second init() — silently disables console upload for the rest of the process, in production. Same silent-and-total signature as the fd-capture bug in #140.

Fix is 20 lines in one file: mark the handler setup_logger_file attaches, and have the guard look for that marker rather than for handlers in general. Capture behaviour unchanged; the guard stays idempotent for pluto's own handler, which is what it was for.

Verification

Each alert's vulnerable_version_range was tested against the resulting locked versions rather than trusting npm audit — its DB differs from Dependabot's. That mattered: ajv, ws, minimatch, and path-to-regexp each carry separate advisories per major line and were already satisfied on both. Result: 62 pip fixed, 0 unresolved; 84 npm cleared by manifest removal.

The console fix was reproduced and verified against a local Pluto stack: test_sync_process.py 50 passed under both pytest 9.1.1 and 8.4.2, and the console/fd suites plus test_e2e_console_logs at 100 passed. The new regression test was confirmed to fail against the old guard, so it genuinely pins the behaviour.

I also ran the tests workflow on main as a control (32078854378) to rule out a pre-existing failure — main was fully green, which is what established the bump as the trigger.

Not verified locally: the torch and DDP suites (torch 2.13.0 is multi-GB; left to CI).

Unrelated issue worth fixing separately

pytest-smoke.yml installs two plugins unpinned, outside poetry's lock:

poetry run pip install pytest-cov pytest-rerunfailures

That makes CI non-reproducible — any third-party release can turn main red with no repo change. Worth pinning or moving into the dev group.

Tested (run the relevant ones):

• Code formatting: bash format.sh — ruff passes, mypy reports no issues
• Console/fd suites verified against a local Pluto stack under pytest 9.1.1 and 8.4.2

📝 Walkthrough

Walkthrough

The PR adds a process-based synchronization architecture document. It updates logger handler detection and development dependency constraints. It removes the Docusaurus documentation site and publishing workflow.

Changes

Process-based synchronization architecture

Layer / File(s)	Summary
Local storage and synchronization flow SYNC_PROCESS_V2_ARCHITECTURE.md	Defines process separation, run-directory layout, SQLite WAL storage, queued records, background uploads, and the init and Run APIs.
Recovery, DDP coordination, and operations SYNC_PROCESS_V2_ARCHITECTURE.md	Documents failure recovery, retries, orphan handling, DDP coordination, recovery commands, configuration, migration phases, and open design questions.

Logger setup guard

Layer / File(s)	Summary
Explicit console handler detection pluto/log.py, tests/test_log_console_handler.py	Uses a Pluto-specific handler marker to distinguish Pluto handlers from foreign handlers. Tests cover both setup paths.

Documentation and tooling cleanup

Layer / File(s)	Summary
Docusaurus site removal .github/workflows/docs.yml, docs/*, scripts/docs-*.sh	Removes the documentation workflow, Docusaurus configuration, pages, blog content, theme customization, sidebar configuration, and publishing scripts.
Development dependency updates pyproject.toml	Updates pytest, torch, and torchvision version constraints and documents their resolution requirements.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 8ac80

The PR updates dependencies, adjusts logging initialization, and removes an unused documentation site; the reported verification is green for the affected suites. The retained architecture document still contains inconsistent run-state, DDP liveness, configuration, and buffering contracts that could mislead implementers or operators, so merge is reasonable with explicit owner follow-up.

Define one canonical run-state and artifact-storage contract.

The schema defines finished, finish_requested_at, fully_synced, and file_uploads. The API writes set_state("status", "finishing") and refers to a files table. The CLI also exposes finishing and crashed, but the schema defines neither state.

Align the schema, Run.finish(), crash transitions, artifact logging, and CLI output before implementation. Otherwise, finish and artifact records can be written to fields or tables that the sync process does not consume.

Replace the “unlimited” buffering guarantee with bounded semantics.

The document defines max_pending_metrics and max_pending_files_mb, and it states that disk-full writes can lose metrics. A network outage can therefore fill the local budget and lose data.

Change “No data loss” and “Unlimited local buffering” to describe bounded retention, drop behavior, and alerting. Add backpressure if the design requires lossless logging.

Make DDP parent liveness track all ranks.

The DDP section says the shared sync process exits only after all ranks die. The supplied launcher passes one parent_pid, and _sync_main checks that single PID.

If rank 0 starts the sync process and then dies while other ranks continue, the sync process can enter orphan mode and exit while those ranks still write to SQLite. Register all rank PIDs or use a shared liveness heartbeat. Exit only when no registered rank remains alive.

documented keys match the actual sync_process_* configuration names, including
flush interval, retry maximum, batch size, file batch size, and shutdown
timeout; alternatively, add an explicit translation layer before _sync_main
reads them. Ensure every documented value is applied rather than silently
replaced by defaults.
