From c321e0f0a30cbe44569a3b58bac4ce6a2d31bd3d Mon Sep 17 00:00:00 2001 From: "russell@unturf.com" Date: Sat, 25 Apr 2026 14:39:02 -0400 Subject: [PATCH] wave14 survey: 7 clean-scan additions (ocaml, Hyprland, knative-serving, tree-sitter, openfaas-faas, sway, micropython) 10 mobile/edge/serverless/PL/WM targets scanned. Honor roll cumulative: 66 projects. Hyprland 46 M7 are intentional geometry primitives. knative 123 M3 are intentional reconciler context plumbing. Build-time scripts (yacc, unlit, eslint plugins) and vendored UI bundles (angular, haddock) account for most remaining M1. --- .../wave14-mobile-edge-pl-wm-survey.md | 77 +++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 whitepaper/outreach/wave14-mobile-edge-pl-wm-survey.md diff --git a/whitepaper/outreach/wave14-mobile-edge-pl-wm-survey.md b/whitepaper/outreach/wave14-mobile-edge-pl-wm-survey.md new file mode 100644 index 000000000..a9dba420d --- /dev/null +++ b/whitepaper/outreach/wave14-mobile-edge-pl-wm-survey.md @@ -0,0 +1,77 @@ +# Wave 14 — Mobile, Edge, Serverless, Languages, Window Managers + +**Survey date:** 2026-04-25 +**Tool:** unmoad (9 active MOAD detectors, HIGH+ severity filter) +**Scope:** 10 projects across mobile (react-native), edge runtimes (workerd), serverless (knative-serving, openfaas), language compilers (ocaml, ghc), embedded (micropython), Wayland window managers (sway, Hyprland), and parser frameworks (tree-sitter). + +--- + +## Summary + +Wave 14 totals 1,467 HIGH+ findings across 10 projects. **Seven new clean-scan honor roll entries** (ocaml, Hyprland, serving, tree-sitter, faas, sway, micropython).

These ARE the geometric primitives Hyprland uses for tiling layout, not lookups against an index. M7 detector matches `_distance(`/`_distanceSq(`/`.overlaps(` substring as candidate Flatland defects, but these are the math primitives. **Detector enhancement candidate already noted in Wave 12 (suppress M7 on distance/metric primitives).** + +## Triage backlog + +1. **Scanner enhancement: Hyprland-style geometry primitive suppression** — same as Wave 12 scipy gap. M7 should not fire on functions whose body computes a distance/metric/overlap rather than performing a lookup. +2. **Scanner enhancement: M3 reconciler-config-store recognition** — knative-style `context.WithValue` for typed config keys (cfgKey{}, deciderKey{}, externalSchemeKey) is intentional Go context plumbing. Suppressing it would clear 100+ M3 hits in knative-serving wave-wide. +3. **react-native private/eslint-plugin-monorepo** — build-time only; if a perf report surfaces from ESLint runtime, re-scan. +4. **workerd Node compat layer** — re-scan if a customer reports Node-compat parsing latency at scale. + +## Method + +Same as Waves 3-13: shallow clone, `unmoad -s high -f json`, filter test/vendor/UI noise, manual triage of strongest source-only candidates per project. **Seven projects added to clean-scan honor roll.** No new UNDF IDs assigned (no patches shipped). + +## References + +- `unmoad` detection engine: `git.unturf.com/engineering/unmoad.com` +- Earlier surveys: `/test-harness-survey/`, `/wave4-linter-ci-survey/`, `/wave5-cicd-iac-survey/`, `/wave6-docgen-webfw-tui-survey/`, `/docs-pipeline-survey/`, `/wave7-mail-dns-storage-vpn-rtos-survey/`, `/wave8-observability-streaming-survey/`, `/wave9-image-pdf-db-editors-survey/`, `/wave10-crypto-text-geo-flutter-survey/`, `/wave11-unix-search-ml-survey/`, `/wave12-sci-static-site-api-gateway-survey/`, `/wave13-vms-devtools-graphql-survey/` +- Clean-scan honor roll cumulative: 66 projects across waves 3-14
