Memory region allocator — red team v9 (post-implementation reality check)
docs/ps1/memory-region-allocator-red-team-v9.md
This is the website shelf page for docs/ps1/memory-region-allocator-red-team-v9.md.
It exists because the project has hundreds of Markdown files and the website
should not pretend the interesting work only happened in the polished essays.
Why this file matters
Active PS1 reference. This is active engineering documentation for the PS1 port. It is close enough to the code that stale claims here become real bugs.
Companion to memory-region-allocator-plan.md v9, implementation status, and the prior red-team rounds (v1-v8).
