Architecture¶

This page describes the overall system design of reader.cpp — how the major components fit together, data flow through the pipeline, and key architectural decisions.

System overview¶

TODO: Refine this diagram to reflect the actual component graph.

Major components¶

TODO: Expand each component into a paragraph once the module pages exist.

Component	Module page	Responsibility
IO Layer	(not yet documented)	Async reads, buffering
Parse Pipeline	(not yet documented)	Format detection, tokenization, AST construction
Document Model	(not yet documented)	In-memory representation
Render Backend	(not yet documented)	Output formatting

Threading model¶

TODO: Describe the threading model — which operations happen on which threads, how data crosses thread boundaries, what synchronization primitives are used.

Memory management¶

TODO: Describe the memory ownership model — who allocates, who frees, any arena/pool allocators, CUDA device memory, etc.

Key design decisions¶

TODO: Enumerate the 3–5 most important design decisions made at the architecture level, with rationale. Each decision should answer: "Why this approach instead of the simpler/obvious alternative?"

External dependencies¶

Performance characteristics¶

TODO: Document known performance envelopes, benchmarks, and bottlenecks.
