CI / build (push) Has been cancelled
runnable-test-suite (parent) — complete. Three sub-tasks all complete: - make-tests-runnable: add requirements.txt pinning pytest==7.4.4, sweep all docs/prompts from bare 'python' to 'python3' (stock macOS/Windows ships python3), add idempotent .venv install block to scripts/install.sh, and add 'from __future__ import annotations' to 3 dashboard modules using PEP 604 union syntax at definition time so they import on Python 3.9+. The PEP 604 bug was caught by the streak verifier itself during implementation. - vram-detect-cross-platform: scripts/vram_detect.py now branches on platform.system() for Linux/Darwin/Windows. macOS path uses system_profiler SPDisplaysDataType (Apple Silicon unified memory via sysctl hw.memsize; Intel Macs via 'VRAM (Total):'). Windows uses wmic path win32_VideoController get AdapterRAM with PowerShell fallback. Linux /proc/meminfo and nvidia-smi/lspci paths unchanged (regression test locks them). Added 14 local-LLM context-window entries (llama-3.1, qwen2.5, mistral, deepseek-r1/v3, glm-4/4.5, gemma-2, phi-3/4) with source-cited model cards. Added _probe_ollama_model() that runs 'ollama list' as a last-resort fallback. run_command() now wraps PowerShell cmdlets on Windows (['powershell', '-NoProfile', '-NoLogo', '-Command', ...]). - vram-detect-cross-platform-tests: 11 new monkeypatched tests in tests/test_vram_detect.py covering Linux/Darwin/Windows branches for detect_ram and detect_gpu_vram, prefix-match for unknown model names, ollama probe, Windows PowerShell wrapper, and a LOCKED regression test for _detect_ram_linux(). All external subprocess/sysctl/wmic calls are mocked; no live hardware probes. Suite total: 235 passed, 0 errors. Verified on this box: gpu_vram_gb 0 -> 32 on Apple M5 (32GB unified memory), target context correctly jumped 12k -> 42k. Subtask-2 implementation was authored by local LLM (gemma-4-26B-A4B-it via headroom proxy @ localhost:8787). The 10-consecutive-clean-pass streak verifier ran as the independent checker model (article #2/#9/#13 in 'WTF Is a Loop? Part 2'). One anti-spin rail fired: local LLM produced inline branches where subtask-3 tests expected private _detect_ram_linux() helper; extracted helper to match the test contract without weakening tests. Parent + all 3 subtasks complete. Prior opencode-subagent implementation of subtask-2 preserved in git stash for reference.

IMPLEMENTATION — vram-detect-cross-platform
Implementer: local LLM (gemma-4-26B-A4B-it-uncensored-Q4_K_M.gguf via headroom @ localhost:8787, model id local-llm)
Orchestrator: opencode (glm-5.2)
What changed in scripts/vram_detect.py
| Function | Author | Change |
|---|---|---|
import platform (new top-level import) |
Orchestrator (mechanical) | Added to support platform.system() dispatch |
detect_gpu_vram() |
Local LLM | Branched on platform.system(). Linux: unchanged. Darwin: system_profiler SPDisplaysDataType parser (Apple Silicon → unified memory via sysctl -n hw.memsize; Intel Macs → VRAM (Total):). Windows: wmic path win32_VideoController get AdapterRAM,Name /format:list + PowerShell fallback. |
detect_ram() + _detect_ram_linux/_darwin/_windows() |
Local LLM + Orchestrator refactor | Local LLM produced inline branches; Orchestrator extracted private helpers to match subtask-3 test contract (_detect_ram_linux()). Linux path byte-identical. macOS: sysctl hw.memsize (no available RAM, reports total). Windows: wmic + PowerShell fallback. |
MODEL_CONTEXT_WINDOWS |
Local LLM | Added 14 local-LLM entries (llama-3.1, qwen2.5, mistral, deepseek-r1/v3, glm-4/4.5, gemma-2, phi-3/4) with source-cited context sizes. Conservative values where YaRN extends context. |
_probe_ollama_model() (new) |
Local LLM | Calls ollama list, parses first non-header row's NAME column, strips :latest. Returns None on any error or if ollama not installed. |
detect_model_context() |
Orchestrator (mechanical wire-up) | Calls _probe_ollama_model() as last-resort fallback after all config-file probes fail. |
run_command() |
Local LLM | On Windows, if first cmd arg starts with Get- or contains CimInstance, rewrites cmd to ['powershell', '-NoProfile', '-NoLogo', '-Command', ' '.join(cmd)] before shutil.which check. Preserves Linux behavior. |
BEFORE vs AFTER on this Darwin arm64 (Apple M5, 32GB)
- BEFORE:
gpu_vram_gb: 0(macOS not supported, falls through to "no GPU") - AFTER:
gpu_vram_gb: 32,GPU: Apple Silicon (unified memory),Total System RAM (Shared VRAM): 32768 MB - Target context correctly jumped 12k → 42k (reflects shared VRAM budget).
- JSON shape unchanged (same 8 keys, same order, same types).
Anti-spin rails that fired
- Signature mismatch on
_detect_ram_linux(): subtask-3's test expected a private helper; local LLM's first refactor put Linux path inline indetect_ram(). Orchestrator (me) extracted the helper to match the test contract — NOT weakening the test, the opposite: making code more testable per the contract. - All other local-LLM output was applied verbatim after passing py_compile.
Streak verifier result
STREAK_COMPLETE attempt=1 clean=10/10
The independent checker model (the streak verifier, per article #2/#9/#13) ran the full suite 10 consecutive times with no edits between. The worker (local LLM) did not grade its own homework.
Test count
- 235 passed (was 224; subtask-3 added 11 cross-platform tests).
- 0 errors, 0 skipped.
- Suite runtime ~3.5s.
