Architecture Decision Records

Each ADR captures one significant, non-obvious decision and why — the rationale that commit messages and code comments don't preserve well. Reverse-documented from the initial implementation session; they record the reasoning as it stood when the decision was made.

ADR	Decision
0001	Build a pure-Rust AD1 reader (no ecosystem crate exists)
0002	Validate against independent oracles, tiered (avoid the LZNT1 trap)
0003	Panic-free, allocation-bounded parsing for untrusted input
0004	Detect and refuse ADCRYPT; no decryption in v1
0005	Emit findings via forensicnomicon::Observation with stable codes
