feat(bus): schedule contract v3, typed records and pure members for bus-only hosts - #143
Merged

Conversation
Relocate the schedule type definitions out of tinyflows-bus and into the dedicated tinyflows-schedule crate, updating the bus module to re-export them so existing callers keep working. This separates the shared data model from the bus implementation. Auto-committed-on: dragonfly
Introduce the schedule types used by the bus to describe when and how scheduled work should run. Auto-committed-on: dragonfly
Introduce the schedule module's supporting types for frequency configuration, record storage, request handling, and store definitions. These provide the data structures the scheduler needs to persist and query scheduled work. Auto-committed-on: dragonfly
Add round-trip serialization tests covering the schedule message wire format so encoding and decoding stay in sync as the protocol evolves. Auto-committed-on: dragonfly
Add chrono to the tinyflows-bus dependencies and register a new wire_tests module behind the test configuration so the schedule wire format can be covered by dedicated tests. Auto-committed-on: dragonfly
The schedule contract types (Attempt, RunRecord, Completion, AgentJobSpec, TooFrequent, MIN_AGENT_JOB_INTERVAL and the output truncation constants) now live in tinyflows-bus and are re-exported from their previous locations, so other crates can depend on the contract without pulling in the scheduler. Auto-committed-on: dragonfly
The gap-description helper is now public and re-exported alongside the interval constants, so callers can format durations without duplicating the logic. Auto-committed-on: dragonfly
Schedules are now persisted through a dedicated store so they survive restarts instead of living only in memory. The bus, drivers, and module layers were wired up to read and write through the new store. Auto-committed-on: dragonfly
Wires a new schedule_members_tests module into the service and widens the visibility of the existing test state, connection helper, and document callbacks so the new tests can reuse them. Also reorders imports in the store tests to satisfy formatting. Auto-committed-on: dragonfly
The proxy test helper now hands the server connection back to callers instead of leaking it with mem::forget, so each test keeps it alive for its own duration and the connection is dropped normally at the end. Auto-committed-on: dragonfly
Adds a temporary test that calls a bogus member name and panics with the resulting error, to inspect how the proxy reports unknown members. Auto-committed-on: dragonfly
Fold the standalone probe into the served surface test and assert on the UnknownMethod error directly instead of matching lowercased message text. Auto-committed-on: dragonfly
The schedule wire records, callback records and agent job spec now live in tinyflows_bus::schedule, so a host can implement the scheduler through tinyflows-bus alone without linking tinyflows-schedule or redeclaring types. The docs describe the new pure members, the added ScheduleStore operations and the CONTRACT_VERSION bump to 3, with tinyflows-schedule re-exporting everything at its old paths and the JSON wire shape unchanged.

A rabbit reads the schedule lines,
And checks the clocks for run-time signs.
Shared types hop onto the bus,
While legacy rows join the fuss.
Calls wait long when work runs late,
Then link in through a module gate.

its existing path in the tinyflows-schedule manifest so the package can be
published to a registry.
Review comments at @docs/tinyflows-bus-design.md:
- Around line 83-91: Update the paragraph to distinguish the wire records in
tinyflows_bus::schedule::types from the other listed items. State that the wire
records and AgentJobSpec, ImportedJob, callback records, StoreOperation,
TooFrequent, and the three constants are importable from
tinyflows_bus::schedule; do not imply the non-wire types live in the types
module.

The legacy `jobs.db` decoding moved out of `import_cron` into a new `legacy_cron` module that returns plain bus records, so a host reaching the scheduler through the bus can replay the file without linking the scheduler implementation. A new `schedule-read` feature gates it, and `ImportReport`'s `wrote` and `invalid` methods are now public so callers can build reports. Auto-committed-on: dragonfly
…d legacy cron reader tinyflows-module: add a static-link feature exporting linked_module() so a host can link the module for tests; give the Execute/Failed/Deliver/ScheduleTrigger callbacks a 2h deadline instead of the bus default of 30s. tinyflows-import: add schedule-read / read_legacy_cron, which decodes jobs.db into tinyflows-bus records without linking the scheduler implementation. Co-authored-by: Medulla <medulla@tinyhumans.ai>
The next_run contract promises an occurrence strictly after the given instant, but the in-process maths returned a one-shot's instant unchanged, so an already-elapsed At schedule was handed back as the next run. The service now returns an error for those, with tests covering past, equal and future instants. Auto-committed-on: dragonfly
The one-shot schedule guard now uses a let-chain instead of a nested if, which keeps the same validation behaviour while flattening the control flow. Auto-committed-on: dragonfly

Why
OpenHuman #7397 cuts the cron domain over to the tinyflows module. Repo rules say a host reaches a loadable component only through its
*-buscontract, but the host still linkstinyflows-schedule/tinyflows-driversfor typed records and for schedule maths, validation and a few store calls. This makestinyflows-bussufficient: no redeclared types, no linking the implementation crates.What moved (wire-compatible)
