Add aggregate network and disk throughput conditions with At least / At most thresholds in KB/s. Active conditions share the existing five-second poller, cached reads and dwell/grace filtering. Sampling ends when the last eligible condition is removed or automation pauses.

Network counters use getifaddrs identities and NET_RT_IFLIST2's 64-bit received/sent values. Disk counters use IOBlockStorageDriver statistics and stable registry identities. Warm-up, unavailable data, reset counters and new devices need fresh baselines. The editor explains aggregate activity, including other apps, VPN interfaces and virtual/backing devices.

Validation: 694 direct Swift tests, 105 release tests, 16 MAS bundle checks and 43 website tests pass. All 645 MAS Swift tests and local Qlty pass. Tests cover legacy settings, sustained/burst/idle sequences, Stop, wake, malformed counters, sampling shutdown, jittered-tick cache regressions and mounted numeric/direction edits for both conditions. Drive Alive fixtures explicitly disable mount watching; dedicated remount tests use their own event center.

Summary by CodeRabbit

  • New Features
    • Added network and disk throughput conditions for automation triggers, with adjustable KB/s thresholds and “At least” or “At most” comparisons.
    • Throughput conditions use sampled traffic over time and default to a 30-second dwell period.
  • Documentation
    • Updated automation and architecture guides with sampling behavior and threshold details.
    • Clarified that aggregate network and disk throughput thresholds are planned for the next beta.

Walkthrough

The change adds network and disk throughput conditions to automation rules. It introduces counter sources, rate sampling, monitor integration, editor controls, tests, and documentation.

Changes: Throughput trigger support

Layer / File(s) Summary
Criteria and throughput sampling
Sources/DilatedCore/Triggers.swift, Sources/DilatedCore/ThroughputSampler.swift, Tests/DilatedCoreTests/*
Trigger criteria accept network and disk throughput measurements and compare them with thresholds. The shared sampler calculates rates from valid counter deltas. Core tests cover sampling, matching, serialization, and evaluator timing.
Counter sources and monitor lifecycle
Sources/DilatedUI/Automation/DiskThroughputSource.swift, Sources/DilatedUI/Automation/NetworkThroughputSource.swift, Sources/DilatedUI/Automation/TriggerMonitor.swift, Tests/DilatedUITests/*ThroughputTests.swift, Tests/DilatedUITests/DriveAliveTests.swift, docs/ARCHITECTURE.md
The counter sources read and decode operating-system counters. TriggerMonitor samples active sources every five seconds, caches readings, and resets sampler state when criteria are disabled, the monitor stops, or the system wakes. Tests cover source decoding and monitor behavior.
Editor and user documentation
Sources/DilatedUI/Automation/TriggersSettings.swift, Tests/DilatedUITests/TriggerEditorInteractionTests.swift, docs/AUTOMATION.md, README.md
The editor adds throughput options, threshold and direction controls, defaults, and criterion summaries. Documentation describes the conditions and sampling behavior. The editor test checks saved criterion values.

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

Merge Risk: Low · previous review 1c5c3

Throughput triggers may react up to one poll interval later than expected because some polling ticks reuse a cached reading. This is a bounded timing issue; lowering the cache threshold to 4 s, as the CPU path does, resolves it.

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 21 functions across 12 files. (3 skipped: 3 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

@coderabbitai review

Review the current combined network and disk throughput change. Threat model: a single-user local macOS app. Check sampling correctness, counter resets, unknown input, trigger timing and privacy. No process names, interface addresses or paths are persisted.

Rechecking the review limit after continuing the other roadmap slices. Current head is 1c5c37f. Threat model: single-user local macOS app. Review the combined network/disk sampling, reset and unknown-counter behavior, trigger timing, and privacy.

Reviewed current head cfd4d3a. The single actionable finding from CodeRabbit pass one is fixed and its thread is resolved. Both sources now use the existing CPU cache margin; deterministic network/disk jitter regressions failed before and pass after. Integrated local verification passed 694 direct Swift tests, 645 MAS Swift tests, release/bundle/web checks and Qlty. The reviewed schedule-grid base is included. No new timer or private traffic/path data is introduced. Fresh current-head CI must finish green before merge. The generic bot docstring advisory is not a repository check.
