… binaries (ADR-0782) (#191) Add OTel span instrumentation across all four VMAFX Go binaries (vmafx-controller, vmafx-node, vmafx-server, vmafx-mcp). Rebased onto master; keeps existing InitOTel API (ADR-0927), integrates ADR-0782 instruments as a pure addition. Span coverage: - vmafx.job.submit: controller SubmitJob gRPC handler (grpc_server.go) - vmafx.scoring / vmafx.frame.extraction: node scoring pipeline - vmafx.onnx.inference: AI path on vmafx-node OTel metrics (pkg/observability/otel_instruments.go, new): - vmafx.jobs.queued / vmafx.jobs.in_flight (UpDownCounters) - vmafx.score_latency_ms (histogram, p50/p99 buckets) - vmafx.frames_per_second / vmafx.gpu_utilization Prometheus additions to pkg/observability.Metrics: - JobsSubmitted / JobsCompleted / JobsFailed struct fields added (missing on master, causing compile failure — supersedes PR #534) Infrastructure: - go.mod/go.sum: fix tab-concatenated lines (pre-existing corruption); add modernc.org/sqlite v1.51.0 (required by vmafx-controller/queue) - cmd/vmafx-controller/queue: add Depth() method (QueueDepthProvider) - deploy/grafana/vmafx-overview.json: Grafana dashboard (new) - deploy/helm/vmafx: optional otel-collector sidecar + values.yaml - docs/observability/otel.md: quick-start, env vars, span names, metrics - ADR-0782; changelog fragment; rebase-notes.md entry All OTel init is non-fatal: missing OTLP collector never blocks startup. go build ./cmd/... and go vet ./cmd/... (exc. pre-existing stale executor_test.go API mismatch in vmafx-node) pass cleanly. Co-authored-by: Lusoris <lusoris@pm.me> Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>

Pull request overview
This PR aims to fix a vmafx-controller observability build break by adding missing Prometheus controller job counters (JobsSubmitted, JobsFailed, JobsCompleted) to pkg/observability.Metrics, plus related module-file repairs and dependency additions. However, the provided diff for this review only contains a changelog fragment, so the functional Go changes described in the PR body are not visible here.
Changes:
- Add a
changelog.d/fixed/fragment documenting the intended observability metrics fix.

…ocumentation gate The standards gate now installs praetor main 25451d8 from the remote module proxy (PRAETOR_REF was f41e74d on master). Every praetor-managed file is regenerated with that engine's own code: adopt (with --verification-max-entries 200000), sync, compile-context and devcontainer --source-root at the pin, which keeps the vmafx-dev-mcp base image. Baseline (ADR-1351): f41e74d re-records 185 entries on this tree with no growth, 25451d8 records 431. All 246 new fingerprints are engine changes, replayed on the same tree against each commit's parent: d7a3778 adds 61 process exits from library code (Python 51, Go 5, Rust 5), 025bbc6 adds 142 long Python functions and 36 recursive ones, 53e7594 adds 7 Go calls without a deadline. They are recorded with --allow-increase and a reason. Documentation gate: praetor fixed cordanaLLM/praetor#532, #533 and #534, so the gate now passes here. .standards.yaml raises max_files to 8192 and max_file_bytes to 4 MiB, and style-excludes the generated ADR index, the ADR row fragments and testdata fixtures, the files the repository's own markdownlint hook already skips. The other 75 findings are fixed in the source: the 14 predictor model cards and their template in predictor_train.py (pinned by test_predictor_card_markdown.py), an MD013 re-enable in the SYCL overview and a fence language in the ADR fragments README. The figure engine under tools/figures/, the docs-figures target, a .gitattributes block and a workflow step arrive with it. Praetor defects, filed or tracked upstream and worked around here: - adopt still refuses to extend the Makefile block because of computed targets such as $(BUILD_DIR): (#537, open). GNU Make finds no docs-lint or docs-figures rule outside the block, so the block is praetor's own DocumentationMakefileBlock() text. - The repository-wide dist/ rule hid tools/figures/dist/; .gitignore re-includes it (#591). - black, ruff and markdownlint would rewrite or flag the locked figure engine; their pre-commit hooks skip tools/figures/ (#578). - Praetor requires the retired numbered workspace root to be ignored (#641, filed with this change). The ADR-1277 contract check accepts only that rule inside praetor's block, skips tools/markdownlint/ when scanning for references and still fails on a local directory. ADR-1351 amends ADR-1277. Also: repository.default_branch: master renders the ruleset for master; REUSE.toml labels the vendored interfig sources and the player bundle; adopt's praetorctl pre-tool hook registrations in .claude/settings.json, .codex/hooks.json and .gemini/settings.json are left out, since audit does not verify them and they change every agent session.
