Drop scratch-only compatibility paths and legacy test scaffolding now that
SlateDB-backed state is authoritative. This removes scratch file fallbacks,
updates docs and UI labels, and moves tests onto durable store-backed helpers.
Active runs deleted through rm --force were removed from server state
without signalling the worker process, which could leave detached
workers orphaned after test cleanup. Terminate the tracked worker
process group before deleting run state and cover it with an
integration regression.
Replace the overlapping usage and cost model with canonical billing
primitives centered on ModelRef, ModelHandle, TokenCounts, and
BilledModelUsage. This also renames the public API and web surface from
usage to billing, removes compatibility aliases, and normalizes provider
usage adapters onto the shared billing vocabulary.
Consolidate CLI and server machine defaults under settings.toml,
including loader renames, writer preservation fixes, same-machine
manifest handling, and docs/test updates for the new config model.
Move --storage-dir and --server-url off GlobalArgs and onto the
leaf commands that actually honor them.
This aligns help, parser behavior, and env-var wiring with the
current command architecture while preserving the intended model
and exec targeting semantics.
Move durable run access and execution control onto the server-backed client,
canonicalize run APIs under /api/v1/runs, and switch CLI integration tests
to a shared test daemon/storage model with shared-state-safe assertions.
The server subcommand and related code were gated behind
cfg(feature = "server"). This removes the feature flag entirely,
making fabro-server a required dependency so the server command
is always available.
