abstract-serve

The provider-neutral shared Serve console. It owns the durable conversation store, queue/hold contract, session picker, and provider adapters. Claude, GPT, Hugpy, and local-model packages may provide adapters without owning the Serve runtime.

Run abstract-serve --no-browser to start the console.

pip install abstract-serve-core
abstract-serve --no-browser                 # standalone
abstract-claude serve                       # the usual entry point — runs these routes

What it owns

abstract-claude serve imports and executes serve-core's HTTP routes. The route handlers left in abstract_claude/server.py are dead at serve runtime — patch serve-core, not abstract-claude, for any serve behaviour.

• Roles: keeper, chat, worker, local are standing serve sessions recorded in roster.json — not Claude sessions. Send to one with POST /api/session/<role>/message.
• Cross-locus relay: session_message / relay accepts to="<locus>" or to="<locus>:keeper"; relay.send_cross posts a comms ping board row on the target locus tagged [from <locus>:<role>], answers 202 queued, and logs to relay.jsonl. Non-keeper cross-locus targets are refused (400).
• Queue: queue-first collator; prompts are sent verbatim — _compile_prompt() only dedups and joins, never runs a model. A model merge exists only as an explicit preview (POST /api/compile {suggest:true}) the operator must apply.
• Interrupt = stop (0.1.16): an interrupted batch is done, never retried, never held; queued items drain at the end of the turn.
• Directives: AC_SESSION_DIRECTIVES_DIR/<role>.md is appended to every turn of that role.
• Rollover sweeps measure context per session (including gpt sessions via the codex rollout) and roll over near the limit.
• Seat report: a sidecar publishes {surface: serve, port, pid} to the central seat_state.
• AC_LOCAL_LLM_URL points at the local model (B) used for previews.

Attention-worthy

• [rollover] sweep #N log lines are routine, not errors (Station's bug scan ignores them since 1.0.152).
• Republishing the same version needs pip install --force-reinstall, or the old files stay.
• Token counters are blank for sessions served by the hugpy engine — it emits no per-turn usage.
