Component selection, identification and substitution
The index currently carries 30 published profiles across 6 component families. Each profile is a specification table, a substitute graph with the trade-off written out, a sourcing assessment and the pinout caveat. Entries clear a publish-date gate in batches; anything not yet due is absent from this matrix and returns 404 by URL.
