Rust Rare1
Active validation line: exact apply/inverse, explicit stream and sideband contracts, implementation still being bounded.
Active R&D module / optional filter
Rare1
reduce the active tail.
Rare1 is a reversible long-tail transform for ID streams. Its job is narrow: move rare events out of the active modeled vocabulary through an explicit sideband, then reconstruct the original sequence exactly.

Current architecture
A pipe, not a dependency.
The current Rust line is being validated as an independent reversible transform. Rare1 can sit after DU3, before a model, or stay out of the pipeline entirely. The surrounding stages remain replaceable.
Global correctness and bounded execution are separate concerns: the logical decision can cover the declared scope while implementation remains chunk-aware and memory-bounded.
DU3 → [Rare1] → [model] → [entropy]

R&D lineage
Keep evidence. Do not inherit the monolith.
Older experiments remain useful as prior engineering evidence, not as architecture we are obligated to reproduce.
Public Python / RFC
The older public implementation and notes preserve prior behavior and results. They are not the current release implementation.
Historical RFC line ↗Ganymede
An integrated R&D experiment showing that useful compositions can exist. Evidence quarry, not the production topology.
Public boundary
Contract outside. Scheduling inside.
Public material can describe scope, sidebands, exactness and module boundaries. Low-level reconciliation and relay choices stay in the private engineering notebook until the design stabilizes.
Next gate
Independent release
When the Rust implementation clears bounded-memory and release receipts, it should ship from its own repository with its own version, checksum and tests.
