Replace the unconditional top-5 keyword recall with a deterministic,
layered gate so only relevant Knowledge entries reach the prompt.
- New src/memory/recall.rs: tokenization with stopword filtering and a
bounded term list; ranking combines lexical relevance, importance and
recency; double gate (min_relevance + min_score) drops weak or stale
matches; hard tokio::time::timeout wraps the SQL search so a slow FTS5
query never delays a turn.
- MemoryConfig gains recall_min_relevance, recall_min_score,
recall_recency_half_life_days, recall_timeout_ms (default 1000ms);
recall_limit is now actually wired instead of being a dead field.
- MemoryManager::recall_for_context exposes the gated path; the
memory_recall tool keeps the raw search.
- Storage::search_memories / search_memories_by_time share a single
jieba-based tokenizer via the new module; search_memories_by_terms
accepts pre-tokenized input for the gated path.
- Docs and example configs (README, about-picobot references, both
config.example.json templates) updated to reflect the new behavior.
Replace the dual task/monitor model, NO_REPLY string protocol, and Agent
self-delivery with a single Scheduled Run path: claim-time JobRun snapshots,
isolated Root/named Agent execution, exactly-once complete_scheduled_run
termination, and Scheduler-owned policy delivery through a persistent outbox.
- SQLite v11: drop job_kind/model/delete_after_run, add job_runs with
status/outcome joint constraints and delivery lease columns; one-shot
BEGIN IMMEDIATE migration with atomic rollback.
- Non-blocking JoinSet event loop with bounded run/delivery concurrency;
terminal commit before any channel I/O; recover unfinished runs as unknown.
- ExecutionOrigin::Scheduled propagates to descendants, completion sink is
top-level only, background delegation downgrades to foreground.
- Typed delivery receipts, fixed target_session_id, idempotent
scheduled:<job_run_id> history insert.
- New cron_runs read-only tool; cron_add/update drop kind/model; WebUI and
Health consume the same JobRun projection.
- Bump version to 1.22.0.
Remove the agent_orchestration enabled feature switch and root_delegates config; delegation edges now derive from the catalog's delegate_targets. Replace the four orchestration design/review docs with a single SUB_AGENT_DESIGN.md. Bump version to 1.13.0.
- drop agent_run_groups table and group_id/scope_kind/scope_id columns (schema v8)
- remove group_id from AgentExecutionContext and recovery group counters
- flatten TasksPage background tab into a per-run list
- add WebUI Agents page with definition CRUD and inline provider/model
- bump version to 1.11.0
- AgentCatalog/definitions with strict Markdown frontmatter, delegation graph,
fail-closed tool scoping, and signal contracts
- structured cancellation (AgentError::Cancelled/TimedOut) across provider
streams, tool batches, and sleep; /stop drives the same terminal state
- schema v6 run/group/inbox persistence with execution-ID conditional
transitions and completion-slot reservations
- ExecutionGate separating run quota from provider/tool step permits
- background completion inbox with hidden-trigger continuation turns,
fairness scheduling, lease release, dead-lettering, and activation recovery
- typed TurnMailbox with two-phase steer admission and atomic consumption at
turn commit; /stop releases admitted steer events back to pending
- emit_signal tool with contract-enforced rate/dedupe/severity/size limits
- WS run/event projection (GetAgentRuns, AgentRunUpdated, AgentEventUpdated),
/api/agent-runs* management endpoints, /api/tasks union, WebUI run tree
and signal cards
- ChannelContext.durable_private persisted for continuation delivery reuse
