Pipfitter workspace bootstrap evidence (2026-07-03)

Evidence receipt for Pipfitter M1 workspace bootstrap: local repo, handbook data, Swift core math, validation PASS, Explorer catalog publication.

Body

Pipfitter workspace bootstrap — evidence receipt

Date: 2026-07-03 Phase: M1 — workspace bootstrap Authority: Local repo work permitted; Explorer catalog promotion via AI lane

Summary

Started Pipfitter product build per UAI Explorer documentation discipline. Created local workspace, seeded free-tier handbook data, implemented Swift core math modules, and published Explorer catalog entries (ecosystem, start-here, this evidence).

Actions taken

# Action Result
1 Created /root/pipfitter workspace docs, diary, data, ios, scripts
2 Copied planning docs from handoff packets docs/planning/
3 Seeded handbook JSON data/ tier-0/1/2 bundles
4 Added Swift core FractionMath.swift, TakeoffEngine.swift
5 Added unit test skeleton TakeoffEngineTests.swift
6 Added validation script validate_handbook_data.py
7 Published Explorer catalog docs ecosystem + start-here + evidence

Validation

python3 scripts/validate_handbook_data.py
pipfitter-handbook-validate: PASS

Includes Audel-cited 45° offset cut length check (~21.5 inches).

Decisions

  • Offline-only v1; no hosted handbook API
  • $6.99 lifetime Pro IAP (no subscription) — planning default
  • Dual threaded take-off tables: Audel-cited + rule-of-thumb
  • iOS Xcode project deferred to Mac operator (build host is Linux VPS)

Boundaries observed

  • No CT121/126 infrastructure mutation
  • No IPT verbatim or ASME PDF content in catalog bodies
  • No secrets in repo or Explorer documents

Risks

Risk Mitigation
No Xcode project yet Mac operator creates project from ios/ sources
Take-off data incomplete (SW/BW) Expand handbook-bundle in M2
Level accuracy vs Stabila Position as pocket reference (~0.1–0.3° calibrated)

Next steps

  1. Mac: create Pipfitter.xcodeproj, wire sources, run tests on device
  2. M2: Level tab + Handbook FTS search UI
  3. M3: Run Builder + Pro IAP StoreKit
