bvtctl - one conversational control CLI

Primary path:
  bvtctl "summarise the current runtime"
  bvtctl ask "run the demo manifest" runtime/examples/demo_manifest.json
  bvtctl chat

Operator commands:
  bvtctl bootstrap
    Build the bootstrap hotgraph from the source registry.

  bvtctl run [usecase] [goal]
    Run bootstrap + bounded packet generation in one pass.

  bvtctl compile
    Compile the canonical system file into the live API, runtime, control, and inference surfaces.

  bvtctl governance
    Show the compiled user-governed next moves from data_prep reduction surfaces.

  bvtctl continuity-status
    Show the primary continuity runtime state from the live NextGen provider, with local fallback only if needed.

  bvtctl continuity-lineage [version_id]
    Show the continuity lineage packet from the provider-first continuity surface.

  bvtctl continuity-surfaces
    Show the materialized continuity surfaces from the provider-first continuity surface.

  bvtctl continuity-flow [version_id]
    Collapse continuity status, lineage, and activation guidance into one operator packet.

  bvtctl continuity-resume [version_id]
    Return the continuity desk packet for the current live version, optimized for resume and next action.

  bvtctl pm-products
    Show the product candidate registry compiled from reduced user-data governance.

  bvtctl pm-resume
    Return the PM operator desk packet.

  bvtctl pm-next
    Return the PM operator packet focused on the next bounded delivery move.

  bvtctl pm-verify
    Run the PM verification path through the benchmark gate.

  bvtctl memory-readiness
    Show the compiled deterministic-memory readiness read for exact lookup, hologram retrieval, and typed ledger gaps.

  bvtctl memory-runtime
    Show the compiled typed memory runtime artifact.

  bvtctl memory-get <unit_id>
    Deterministically retrieve one typed memory unit by exact id.

  bvtctl memory-as-of <unit_id_or_logical_id> <timestamp>
    Deterministically retrieve the typed memory unit that was effective at a given time.

  bvtctl memory-expand <unit_id>
    Expand one typed memory unit through its deterministic relation edges.

  bvtctl continuity-activate <surface_id> [version_id]
    Activate one continuity surface through the live provider.

  bvtctl continuity-materialize [manifest]
    Instantiate the continuity runtime through the live provider, with local materialization only as fallback.

  bvtctl continuity-materialize-local [manifest]
    Materialize the local fallback continuity slice through the existing runtime and receipts.

  bvtctl execute [manifest]
    Run one bounded local work manifest and emit a receipt.

  bvtctl benchmark
    Run the standalone control benchmark.

  bvtctl corpus-packets
    Build the pilot corpus reasoning packets for the golden abstractions.

  bvtctl self-improve "<goal>"
    Propose one bounded repo improvement through Codex CLI.

  bvtctl self-improve-apply "<goal>"
    Propose, apply, and benchmark one bounded repo improvement.

Inspect surfaces:
  bvtctl packet [usecase] [goal]
  bvtctl policy
  bvtctl scorecard
  bvtctl runtime
  bvtctl api
  bvtctl inference
  bvtctl context
  bvtctl bootstrap-context
  bvtctl ux
  bvtctl kernel-plan

Why:
  the default front door is conversation; the other commands are explicit operator tools.
