Scope

Stacked on Phase 4D-R2a. Add a backward-compatible per-request access context to the static MMS object/dispatcher API so association-aware BRCB writes can be implemented without changing legacy object callbacks.

Implemented

• opaque MmsStaticRequestAccessContext carrying association_id + stable binary Owner identity
• optional MmsStaticContextualWriteCallback appended to MmsStaticObjectEntry
• legacy aggregate initializers remain source-compatible
• contextual write callback takes precedence when present; legacy writes continue unchanged
• dispatcher dispatch() overloads accept an optional access context with a default empty context
• connection policy now has caller-owned fixed-capacity association/Owner identity storage and exposes it as an access context
• no IP/socket/TLS dependency in the portable identity model

Still to complete in R2

• pass the connection policy access context into the established connection dispatch call
• add connection lifecycle/association-loss hook for ResvTms semantics
• expose BRCB operational attributes (Resv, ResvTms, Owner, RptEna, EntryID, PurgeBuf)
• encoded multi-client MMS hard-profile evidence

Physical ESP32-P4 flash acceptance remains READY_NOT_MEASURED.

Closing as superseded by #51, which consolidated the cumulative BRCB R1–R3 implementation onto current main. The contextual-write tranche here is preserved as history, but no longer needs to remain active.
