Work-Package: M00-QAR-INTEGRATOR-CLOSEOUT-001
Agent: sindo-main-codex
Tests: post-merge render baseline dry-run; comparator self-test; coordination and documentation gates

M00-QAR-COORD-CALIBRATION-001 — Renderer coordinate calibration

Ownership

Target: M00
Program: QAR
Owner/Agent ID: sindo-main-codex
Branch: work/sindo-main-codex/m00-coordinate-calibration
Lease expires UTC: 2026-07-13
Integrator: milestone integrator

Outcome

Record the five observed build 12340 camera positions as non-proprietary golden coordinates and determine whether the existing WoW/Godot position formula round-trips them.

Non-goals

Introducing the M01 production CoordinateMapper contract.
Changing terrain, placement, WMO, liquid, or streaming behavior.
Claiming camera composition parity from coordinate round-trip alone.

Paths

Exclusive: src/tools/verify_render_coordinate_calibration.gd
Shared/hotspots: src/tools/render_baseline_manifest.json, renderer baseline documentation
Generated/ignored: original-client screenshots and local reports

Contracts and data

Public API/events: none; headless diagnostic only
Schema/format version: additive checkpoint calibration metadata, manifest schema remains 1
Migration/compatibility: existing capture consumers ignore additive fields
Consumers: M00 fidelity workflow and future M01 golden fixtures

Dependencies

Requires: five accepted original-client build 12340 viewpoints
Blocks: diagnosis of paired camera/placement mismatch
External state: screenshots remain outside Git

Verification

Commands: coordinate calibration probe, baseline manifest, coordination and documentation gates
Fixtures: five reference_wow_camera values in renderer manifest
Fidelity evidence: positions were observed in build 12340 during the paired session
Performance budget: negligible headless arithmetic

Documentation deliverables

Inline public API docs: diagnostic script header
Module specification: renderer verification/source map update
Data-flow diagram: baseline calibration flow update
Sequence/state/dependency diagrams: not applicable; stateless synchronous probe
Source map/status updates: renderer module and baseline document

Simplicity and naming

Important names introduced: reference_wow_camera, maximum_round_trip_error
Simplest considered solution: direct formula probe over manifest fixtures
Rejected complexity/abstractions: production domain mapper before M01
Unavoidable complexity and justification: none
Measured optimization evidence: not applicable

Status

State: ready
Done: five golden camera points, headless round-trip probe, runner integration and documentation
Next: integrator review; diagnose terrain height/placement/composition separately
Blocked by:

Handoff

Commit: branch HEAD
Results: five points passed with maximum mapping/round-trip error 0.000015
Remaining risks: correct position arithmetic does not prove terrain height, placement or camera direction parity
Documentation updated: docs/RENDER_BASELINE.md, docs/modules/world-renderer.md
