Forming Quality Analyser

13 agents contributed to this build. Each agent picked up to 5 of its most significant concrete contributions.

App Designer

app-designer · 2026-05-11T00:00:00Z
  1. Paired every slider with a typed numeric input + visible [min–max]/default per Loom UX policy
  2. Refactored /plot/fld and /plot/hardening into iplot_*.html templates with axes-only Plotly + ready-ping
  3. Added /api/preview JSON curve endpoint driving debounced (~200 ms) postMessage updates to iframes
  4. Wrote forming-overrides.css with copper accent, dashed-rule panels, KPI strip, engineering-drawing verdict badge
  5. Externalised controls into forming_controls.js — two-way slider↔number bind, 400 ms ready-ping fallback

App tester

app-tester · 2026-05-11T00:00:00Z
  1. Verified /healthz, /, /docs, /plot/fld return 200 via in-process TestClient
  2. Confirmed POST /api/assess returns valid QualityResult for DP800 default card (verdict=PASS, score=100%)
  3. Validated 5/6 engineering-drawing design-token markers present in / template
  4. Confirmed canonical cbc-tokens.css and cbc-components.css ship in webapp/static/css/
  5. Installed missing httpx dep into .venv to unblock TestClient probing

Board Selector

board-selector · 2026-05-11T00:00:00Z
  1. Added volvo-press-technician advisor: maps production sensor data to shop-floor quality diagnostics
  2. Added volvo-imq-inspector advisor: defines quality-output certificate contract and deviation paths
  3. Retained mandatory mats-sigvant-advisor and johan-pilthammar-advisor for forming/material-card coverage

Forming-Quality Math

calibration-math-auditor · 2026-05-11T00:00:00Z

  4. Authored tolerances.yaml with 4 paper-anchored bands feeding the audit gate
  5. Added Hypothesis property tests: Hill convexity, Hollomon monotonicity, FLC sign

Domain research brief

domain-researcher · 2026-05-11T09:00:00Z
  1. Loaded fe-simulation + ml-for-engineering skills; scoped build as FE-surrogate + production-data quality-predictor
  2. Identified 10 applicable methods (AutoForm Sigma, FLC-based FI, MLPRegressor, GP, SHAP, ensemble UQ, anomaly detection, active learning, k-fold, LOGO)
  3. Defined 7 decision rules (ML/R2 realisation-split, ML/R3 k-fold, ML/R7 UQ, ML/R8 SHAP, ML/R4 LOGO, FE/R2 NIP, FE/R7 friction)
  4. Documented 6 common errors with root-cause + fix (Sigma leakage, missing UQ, missing SHAP, HP search on test set, thickness mismatch, global friction)
  5. Wrote hand-off instructions for 6 downstream agents: scaffolder, ml-validator, math-auditor, app-designer, data-validator, imq-inspector

App Scaffolder

engineering-app-scaffolder · 2026-05-11T10:30:00Z
  1. Scaffolded FastAPI app (app/main.py): /api/assess endpoint wired to Hill-1948 + Keeler-Brazier math from app/math.py
  2. Authored WORKSPACE_CONTRACT.md: per-parameter bounds table (6 params) with source-of-bounds citations for all sliders
  3. Wrote webapp/templates/index.html: dual plot-tile layout (FLD + Hollomon), live slider -> /api/assess -> verdict badge flow
  4. Stubbed app/manual_content.py with 5 ManualEntry records keyed to Hill1948, Hollomon1945, Keeler1977, Marciniak1967
  5. Wired CI (.github/workflows/ci.yml) and weekly security audit (security.yml) per github-actions-ci skill

Session Handoff

handoff-writer · 2026-05-11T12:30:00Z
  1. Wrote LOOM_HANDOFF.md (8 sections, 12 agents, 5 next-step suggestions) for cold-resume
  2. Surfaced 2 unresolved BLOCKING Volvo IT findings (auth + data residency) prominently in §7
  3. Captured all 4 contracted math.py function signatures verbatim from WORKSPACE_CONTRACT.md
  4. Documented deferred deploy-gate decision (subdomain-deployer awaiting user execute confirmation)
  5. Mapped 9 continuation tasks to specific agents + skills for standalone Claude Code resume

Test Suite Runner

pytest-runner-summarizer · 2026-05-11T00:00:00Z
  1. Installed pytest + hypothesis into .venv (both absent from initial scaffold)
  2. Identified missing .plot-tile CSS class in cbc-components.css; added iframe wrapper rule to fix test_design_components_present
  3. Ran 16 tests (6 example-based, 3 property-based with 100 Hypothesis examples each, 7 webapp smoke); all pass after fix
  4. Ran 4-quantity numerical tolerance audit against tolerances.yaml; all PASS (Hollomon d=6.1e-2 MPa vs band 0.5, Hill48 d=5.7e-14, FLD0 d=4.8e-7, thinning d=2.8e-17)

Security Review

security-reviewer · 2026-05-11T00:00:00Z
  1. Verified HSTS max-age=63072000+includeSubDomains and full security-header suite on every response
  2. Confirmed CSP has no unsafe-eval; flagged 'unsafe-inline' in script-src as residual risk for plot inline init
  3. Confirmed no upload routes, no auth surface, no DB — attack surface limited to bounded numeric Pydantic inputs
  4. Verified Dockerfile installs libmagic1 + chromium; rendering runs --no-sandbox in container only (acceptable)
  5. Confirmed no secrets in code; CISMA_SECRET_KEY generated by deploy; APP_ENV/data dir read from env

Deploy to VPS

subdomain-deployer · 2026-05-11T12:10:00Z
  1. Produced 7-step deploy plan targeting sheet-metal-quality-preview.data-driven-models.cloud
  2. Confirmed .deploy.yml is correctly configured (port 8000, /healthz, persistent volume, env vars)
  3. Identified CISMA_SECRET_KEY as auto-generated secret (not baked into config)
  4. Emitted loom-decision gate — awaiting user execute/plan-only confirmation before live deploy

Manual Writer

user-manual-writer · 2026-05-11T00:00:00Z
  1. Authored app/manual_content.py with 18 ManualEntry dicts and 4 Reference dicts covering all public math.py quantities and routes
  2. Added Reference + ManualEntry dataclasses and dataclasses.asdict() pattern to fix dict-style access in /manual route
  3. Wrote docs/manual.md (offline flat mirror) with inputs table, 3 worked examples, limitations, and numbered references
  4. Wired KaTeX auto-render (delimiters $/$$/$$) + Mermaid.js ESM via jsdelivr into webapp/templates/manual.html {% block scripts %}
  5. Authored pipeline flowchart (Mermaid, CiSMA paper-aesthetic theme) inside the pipeline guide entry documenting the full data flow

Volvo IT Sign-off

volvo-it-reviewer · 2026-05-11T08:45:00Z
  1. Flagged missing auth on /api/assess as BLOCKING — production data leaves Volvo perimeter without access control
  2. Flagged absent data residency documentation as BLOCKING — no DPA/in-memory-only statement for BTH-hosted infra
  3. Identified external CDN dependencies (cdn.jsdelivr.net, cdn.plot.ly) as advisory risk for Volvo shop-floor browsers
  4. Identified Chromium in production container as advisory CVE/attack-surface risk
  5. Confirmed PASS on security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options), input validation, and stateless data handling

Web App Reviewer

webapp-reviewer · 2026-05-11T08:30:00Z
  1. Identified 2 blockers: app/main.py absent (no FastAPI app) and index.html template absent (primary route dead)
  2. Flagged full math.py API drift vs WORKSPACE_CONTRACT: 4 contracted functions absent, replaced by Hill-48/FLD set
  3. Confirmed pyproject.toml pins are correct: fastapi<0.120, starlette<1.0, pydantic>=2.5,<3
  4. Confirmed cbc-tokens.css + cbc-components.css present; base.html correctly links both canonical CSS files
  5. Flagged missing tests/test_routes.py and missing pypdf page-count assert in contributions_pdf.py
