summary: A weekly recap covering AL Runner v2 improvements closing emulation gaps against real BC, reference suite growth through sandbox-verified testing, bc-code-atlas enhancements for cross-app call graphs with deterministic global IDs, AL-Go fast lane hardening for multi-workflow stability, and compile-time benchmarking showing NuGet-sourced compilation is faster due to smaller dependency caches.

# Weekly Recap: August 7-14

[Read the post](https://stefanmaron.com/posts/weekly-recap-2026-08-14/) · Stefan Maron (Stefan Maron, MVP) · 2026-08-14 · 1839 words · tier community · reviewed (checked by Opus)

> A weekly recap covering AL Runner v2 improvements closing emulation gaps against real BC, reference suite growth through sandbox-verified testing, bc-code-atlas enhancements for cross-app call graphs with deterministic global IDs, AL-Go fast lane hardening for multi-workflow stability, and compile-time benchmarking showing NuGet-sourced compilation is faster due to smaller dependency caches.

## Key points

- AL Runner shipped 85 PRs fixing emulation-to-real-BC divergences in rename propagation, calc formulas, test paging, and event dispatch
- Added safety mechanisms like count-baseline floors to prevent silent test vanishing and reclassified permanent gaps from temporary ones
- bc-code-atlas global_id enables cross-instance call graphs by using deterministic identity-based keys independent of indexing
- Fast lane hardening fixed silent build skips in non-PR workflows and missing-package errors in compile-only projects
- Compile benchmarking revealed NuGet folder dependency caches are faster than artifact folders because they only contain actual closure, not all bundled apps

## Quotes

- "run the corpus against real BC, find a case where the runner and BC disagree, fix it" (Explains the systematic approach to closing emulation gaps through measured comparison rather than assumptions)
- "if a measured run disagrees with the assumption, the measurement wins" (Illustrates the core testing discipline of validating against real BC behavior as the authoritative reference)

## AL objects mentioned

As named in the post. A name that matches one object page by exact type and name links to it; the others stay as named.

- other "AL Runner"
- other "bc-code-atlas"
- other "AL-Go"
- other "BusinessCentral.AL.Language.Tests"
- other "MsDyn365Bc.On.Linux"
- other "al-go-compile-bench"

## Context

- Features: AL Runner emulation correctness, Event dispatch with EventSubscriberInstance Manual, TableRelation rename propagation, TestPage AutoSplitKey numbering, Cross-app call graph navigation, Deterministic global IDs, AL-Go fast lane multi-workflow support, TLS reverse proxy support for containers
- Versions: BC 27.x, BC 28.x
