v1.5.3 - Cable Schedule i18n, Tooltip & Telemetry Fixes

QA pass over the v1.5.2 cable-schedule rework found and fixed five issues. All browser-verified: 12/12 checks, 0 console errors, health score 92 → 100 on measured categories.

Fixes

i18n regression (high). The building-card subtitle called t('common.buildingLoads') — a key that does not exist. Because I18nProvider only falls back when i18n.exists() fails, a hardcoded English building loads fragment rendered in every locale:

de: 3 Etagen · 0 Techniketagen · 0 Wohnungen / Einheiten · 0 building loads
ar: 3 عدد الطوابق · 0 طوابق الخدمات · 0 شقق · 0 building loads

In Arabic this was worse than wrong text: the Latin fragment rendered LTR inside an RTL line, landing on the wrong side of the sentence. Repointed at cableSchedule.buildingLoads; now renders Gebäudelasten / أحمال المبنى / Carichi Edificio.

Column tooltip (medium). title={t('cableSchedule.load', 'Circuit & Tag identifier')} — the key exists and resolves to Load, so the fallback was silently discarded and the header advertised a different column. Now a literal, matching its 13 siblings.

10 orphaned i18n keys removed from all four locales, left behind when the Full Width and Phase Details toggles were deleted in 6bd935b. Verified unreferenced and unreachable by dynamic key construction.

Dev hygiene. Strict-Transport-Security (2-year preload) and CSP upgrade-insecure-requests were served in development, so Chrome attempted HTTPS navigations against the HTTP dev server — four ERR_CONNECTION_RESET console errors on every /login load. Both are now production-only.

Privacy. Clarity telemetry was running against local dev. layout.tsx carried a second, duplicated inline script with the project ID hardcoded, bypassing NEXT_PUBLIC_CLARITY_PROJECT_ID entirely — so no local configuration could disable it. layout.tsx now renders the existing ClarityAnalytics component, making the component the single source of truth and the env var authoritative. Local telemetry requests went 6 → 0.

Tests

Added src/i18n/locales.regression-1.test.ts (6 tests) pinning the i18n keys these fixes depend on and asserting the two touched pages reference only resolvable keys. Proven non-vacuous: reintroducing the bad key fails the suite with expected [ 'common.buildingLoads' ] to deeply equal [].

A repo-wide "every key resolves" check was deliberately not added — 73 keys are already missing across 960 t() call sites as pre-existing debt, so such a test would ship red. The new test scopes to the two affected pages with an explicit allowlist that should shrink.

Verification

• tsc --noEmit clean
• eslint 0 errors (4 pre-existing unused-var warnings in cable-schedule)
• vitest 795 passed across 68 files
• next build succeeds

Also confirmed working

Sticky first column (pinned through horizontal scroll), no page overflow at 375/768/1280/1920, per-phase L1/L2/L3/Neutral columns correctly removed, MethodSelector unclipped at 375px, Load-library tab label localized in all four languages, RTL mirroring.

Not covered

No accessibility audit (axe/Lighthouse not run) and no performance measurement. The cable-schedule editing flows — inline size/method/insulation edits, Recalculate All, Apply-to-database, Default Settings — were not exercised; the diff touched the table shell, not the cell editors.

v1.4.2 - Voltage Drop Upsizing Rationale in Cable Ampacity Trace

Changes in v1.4.2

• Voltage Drop Upsizing Detection: The Calculation Trace Engine now detects when a conductor is upsized above its base thermal requirement ( \ge I_n$) solely to satisfy allowable voltage drop limits (IEC 60364-5-52 §525 / NEC 210.19(A)).
• Voltage Drop Upsizing Gate Step: Adds a dedicated mathematical step showing the base thermal size, the excessive voltage drop at that size over the circuit length, and the upsized cable size that brings the voltage drop within compliance.
• Trace Parameters Provenance: Displays \Sizing Governing Factor: Voltage Drop, \Base Thermal Requirement, \Circuit Route Length, and \Calculated Voltage Drop (ΔU).
• Clarified Compliance Margin: Explains continuous margin above $ in the trace compliance banner as a consequence of voltage drop upsizing.
• Full Internationalization: Added English, Arabic, German, and Italian translations for all new trace labels, parameters, and margins.
• Build & Tests: All 720 tests pass across 60 test files; production build verified with Next.js Turbopack.

Release v1.4.1

Release v1.4.1 - MDB and SMDB Circuit Breaker Hierarchy & Apartment MCB Sizing

• Upstream Feeder from MDB / Subpanel Main Incomer: Always an MCCB (IEC 60947-2, minimum 160AF, 36kA+ or ACB >= 630A).
• Subpanel Outgoing Circuits: All circuits <= 63A default to domestic MCB (IEC 60898-1). Heavy equipment (> 63A or high-power 3-phase motors) uses an MCCB.
• Apartment Circuit Sizing: Sized to design demand current (e.g. Ib = 23.9A -> 32A MCB) instead of 100% undiversified connected load.
• Trace Modal Engine: Displays realistic modular DIN-rail frame, Icn rating, and IEC 60898-1 citation for MCBs.

v1.4 - Full-Width Application Layouts & Centered Riser Diagram

Changes in v1.4

• Full-Width Application Layouts: Standardized wide container dimensions (\w-full max-w-[1680px] mx-auto min-h-[80vh]) across Engineering Reports, Breaker Schedule, Load Calculator, Protection Coordination Studio, Panel Designer, Vertical Riser, Dashboard, and Administration modules, aligning with the Cable Schedule design standard.
• Centered Vertical Riser SVG: Wrapped the Vertical Riser diagram in a responsive centering container with dynamic zoom-aware bounding (\w-fit min-w-full flex justify-center), eliminating left-margin bias on wide viewports.
• Report Logo Protection: Enhanced logo rendering constraints with \max-w-[140px]\ alongside \h-6\ to guarantee submittal page layout integrity against panoramic aspect ratios.

v1.3.9.2 - Server-Side Headless Chromium PDF Generation & TrueType CMap Compliance

Changes in v1.3.9.2

• Server-Side Headless Chromium PDF Generation (1-Click Download):

  • Added authenticated endpoint GET /api/projects/[id]/pdf generating executive submittal packages in memory using Puppeteer and headless Chromium (@sparticuz/chromium on serverless Linux, local Chrome/Edge auto-detection on Windows/macOS).
  • Configured with landscape A4 dimensions, high-DPI scaling, and maxDuration = 60.
  • Stitches all 8 schedules (CoverPage, LoadSchedule, MDBSchedule, CableSchedule, BreakerSchedule, VDSchedule, ShortCircuitSchedule, BOMSchedule) with ReportHeader and standalone Base64-compiled CSS.

• PDF Print Buffer Overflow & Hidden Calculation Cell Fixes:

  • Eliminated font-outlining bezier explosion that caused printer spooler memory exhaustion on multi-page browser prints.
  • Exempted interactive calculation elements inside table cells (<TraceableCell>) from @media print { [role="button"] { display: none } }, ensuring full visibility across all printed tables.

• Standardized Apparent Power (kVA) as Primary Engineering Metric:
