2026 Timeline (Week-by-Week)¶

Snapshot: 2026-05-18 Canonical schedule source: 47-gtm-plan — submission target NLT 2026-07-09. Live status sources: 11-weekly-updates for sprint closeouts · 32-tb11-bug-tracker for bug inventory. Scope of this document: week-cadence philosophy and the historical Jan–Mar 2026 execution log. Current milestone windows and forward sprint plan have been removed from this revision — refer to the canonical sources above.

Current Schedule¶

Current milestone windows: see 47-gtm-plan. This document covers week-cadence philosophy and the historical Jan–Mar 2026 execution log only. Hard gate rule (security testing does not begin until full validation completion evidence is present for all active configurations) still stands.

Historical Context¶

Sections below are preserved as the pre-snapshot planning record. They contain date assumptions that were superseded first by the March 23 rebaseline and again by the 2026-05-18 snapshot. Treat dates here as artifacts, not commitments.

Note: This plan was a working draft. Some technical details (exact file provenance, build parity, vendor timelines, pricing, and Autodesk product capabilities) needed verification as the full legacy tree was inventoried.

Schedule philosophy¶

The project runs a weekly cadence with:

1 weekly update
1 build artifact whenever meaningful progress lands
explicit phase gates (P1→P2→P3→P4)
Q4 dedicated to stabilization + partner demo readiness

This cadence remains in force; only the dated schedule has moved to doc 47.

Budget Milestones (January 27, 2026)¶

Dates below are budget-planning targets from January 2026. For committed schedule, see 47-gtm-plan.

Historical 2026 Macro Timeline (pre-snapshot)¶

Preserved for context. For current quarter direction, see 47-gtm-plan.

Q1 2026 (Jan–Mar): P1 execution + distribution strategy pivot 🔧¶

✅ Build artifacts archived (Completed 2026-01-16)
✅ Installer analysis complete, WiX decision documented (Completed 2026-01-20)
✅ isDcc decompilation of v3.60 InstallShield → setup.rul (4,163 lines)
✅ Cost analysis complete — WiX (FREE) selected over $500-2000 alternatives 💰
✅ Proxmox VM infrastructure — Tower converted, Tailscale + LegacyUpdate.net (Jan 27) 🖥️
✅ Multi-OS testing COMPLETE (Feb 10) — XP/Vista/Win7 all passed, 9 bugs documented
✅ Win10 testing COMPLETE (Feb 13-17) — Win10x32 fully working, Win10x64 fully working (after Wow6432Node COM fix Feb 17)
✅ Total Uninstall inventory validated — 152 files, 5.5 MB as WiX payload source
✅ Auto-config script created — Configure-ConstructiVision.ps1 handles AutoCAD integration
⏹️ P1 InstallShield Sprint ABORTED (Feb 13) — Low ROI, proceeding directly to WiX
❌ WiX Installer Development ABORTED (Feb 28) — Distribution pivoted to VLX .bundle format for Autodesk App Store
✅ P0 Automated Validation Sprint (Mar 1-4): AutoIT test automation built, 18 bugs found and 17 fixed (Bugs 22-38), P0 Steps 0-2 PASS on 5/6 VM configs
✅ Architecture Discovery (Mar 1): VLX was compiled from source code not in repo — progcont routing mismatch between VLX and source mode
⚠️ Win10 PB11 ABANDONED (Bug 37): WinHelp() compiled into VLX, Win10 removed WinHlp32.exe — TB11 source-mode only for Win10

Q2 2026 (Apr–Jun): Validation closure + integration and design transition¶

P1–P2 sub-dialog feature validation (59 manual workflows from doc 31)
Comprehensive parity validation (45-tb11-parity-test-plan) — 92 tests across 7 gates (G1–G8)
VLX compilation from validated source (deferred until P1 stable)
.bundle packaging for Autodesk App Store
NanoCAD 25 + AutoCAD 2026 compatibility testing

Q3-Q4 2026 (Jul–Nov): P3 modern AutoCAD compatibility, security testing, and ADN prep¶

Run cleanly on AutoCAD 2026
Modern packaging (.bundle format) + UI adjustments
Regression suite runs on target
Join ADN Developer tier (~$500/year for technical support)
Prepare Autodesk App Store submission (screenshots, docs, EULA)
Request early AutoCAD 2027 access
Sunset VM-based distribution model

Q4 2026 (Nov–Dec): P4 hybrid cloud + dual distribution + demo hardening¶

Subscription foundations + artifact pipeline
Stabilization, performance, “demo polish”
White Cap demo readiness (target)
World of Concrete readiness by end of 2026

Detailed weekly cadence (recommended)¶

Every week (non-negotiable)¶

Update weekly-update.md (see template)
Maintain:
- phase status (P0–P5)
- risks + mitigations
- decisions made
- demo readiness notes

Every 2 weeks (target)¶

Produce a tagged build artifact (even if internal)
Run smoke tests
Update regression suite results

Monthly (end of month)¶

“Milestone review”:
- what shipped
- what slipped
- updated risk outlook
- next month objectives

Historical 2026 week plan (Weeks 1–16, Jan–Mar)¶

Week 8 (Feb 10-13): Win10 Testing + P1 Sprint Decision ✅ COMPLETE — Win10 32-bit working; P1 InstallShield Sprint ABORTED; auto-configuration script created

Weeks 9–13 (Feb 13 – Mar, Target 2026-03-31): Bug fixing sprint + P0 validation + .bundle pivot 🔧 (Historical)

Week 9 (Feb 13 – Feb 20): WiX Foundation ❌ ABORTED (Feb 28) — distribution strategy pivoted to VLX .bundle for Autodesk App Store
Week 10-11 (Feb 20 – Mar 3): TB11 Source-Mode Bug Fixing Sprint — 18 bugs found and 17 fixed (Bugs 22-38)
Week 12 (Mar 3-7): P0 Automated Validation Sprint ✅ — AutoIT scripts created, OCR comparison pipeline, P0 Steps 0-2 PASS on 5/6 VM configs
Week 13 (Mar 10-14): P0 Steps 3-6 (Drawing & Dialog Verification)

Weeks 14–16 (Mar 17–31): Progcont reconstruction sprint (Historical)

Reverse-engineering of VLX progcont routing logic; implementation of progcont reading in source-mode csv.lsp
P0 Steps 7-12 + Graduation milestone
Reconstruction effort flagged the dependency chain that drove the March 23 rebaseline

Forward schedule (Weeks 17+)¶

Weeks 17 onward are tracked by 47-gtm-plan §12-week schedule (submission NLT 2026-07-09) and 11-weekly-updates sprint closeouts. The pre-snapshot week-by-week plan (Apr–Dec 2026) has been removed from this document because it was based on a 2026-03-31 P0 baseline that did not hold; perpetuating it here would re-introduce the contradictions the 2026-05-18 snapshot is meant to clear.

Date realism note (World of Concrete)¶

World of Concrete 2027 is scheduled for January 19–21, 2027 (Education: Jan 18–21). The intent is:

Demo freeze by December 15, 2026 to ensure stable, demo-ready product
Rehearsal cadence: monthly demos starting July 2026, weekly starting October 2026
