Changes in version 0.0.1.9001                      

  - Accounts for the complete transformed provider context before
    compaction. Reported token counts are reused only for the same
    model, prompt, tool, operation, and activation revision. Agent run
    results include cumulative typed usage and nominal-cost summaries.

  - Marks prepared tool-call arguments explicitly, so policy events and
    execution share one typed argument value without running wire
    preparation twice.

  - Represents idle, running, and compacting phases as S7 values. Agent
    behavior no longer branches on phase-name strings.

  - Adds the structural SessionJournal contract and an in-memory
    implementation. Assistant partials remain in the active turn and
    only terminal messages enter the append-only journal; reset is
    represented by a committed entry instead of erasing history.

  - Adds asynchronous session synchronization and compare-and-append
    positions. An idle agent can rebuild its projection from an existing
    journal, while a stale writer receives RhoSessionConflictErrorValue
    before journal mutation.

  - Uses only counted usage observations when projecting context usage;
    an unavailable provider observation causes a complete-context
    estimate.

                     Changes in version 0.0.1.9000                      

  - Gives the provider-operation agent-loop fixture enough time on
    slower build hosts while retaining an explicit test timeout.

  - Adds the experimental asynchronous multi-turn agent loop, ordered
    lifecycle events, tool scheduling, queues, cancellation, and policy
    generics.

  - Adds append-only session entries, projected provider context,
    semantic compaction, typed skip and failure outcomes, threshold
    compaction, and one provider-input recovery attempt selected by an
    open S7 generic.
