Phase 1 — semantics doc
docs/002. hsmc-semantics-formal.md
Phase 2 — deterministic execution journal
hsmc/src/journal.rs (TraceEvent, JournalSink, ActionKind)
hsmc-macros: __chart_journal! emission at every observable site
(entry/exit/action/transition/timer arm-cancel-fire/during/emit/
event delivery/terminate). Per-state during count helpers, stable
chart-hash via FNV-1a. Action observation moved out of run_action
and into call sites so ActionKind is accurate.
Public API on the generated machine: journal(), take_journal(),
clear_journal(), CHART_HASH.
Phase 3 — verification crate (Creusot scaffolding)
verification/{Cargo.toml,mise.toml,requirements.txt,INVARIANTS.md}
verification/src/{event_queue.rs,timer_table.rs} — Pearlite
contracts on simplified mirrors of the runtime types. cargo
creusot generates Coma IR cleanly; VCs not yet discharged.
Correspondence tests drive the verified mirror and the runtime
type with the same op sequences and assert observable parity.
Tests — 113 deterministic-flow tests across 22 files. Each compares a
hand-built expected journal byte-for-byte against actual, anchored
to a spec section: initial entry, lateral/self/up transitions,
bubbling, timers, emit, ordering, durings, step/dispatch
equivalence, root-targeting, current_state, termination.
Tooling — mise.toml (root): stable Rust + cargo subcommands.
verification/mise.toml: pinned nightly-2025-11-13 + opam + python
venv + uv. just verify is fully self-installing.
Bug fix — root state targetable by the chart's own name (e.g.
`on(Trig) => ChartName;`) per spec §"How transitions work".
CHART_HASH — stable FNV-1a fingerprint over the chart's structural
definition; mismatch on replay = different chart.
Add LICENSE-MIT and LICENSE-APACHE at workspace root and in each member package so the dual MIT OR Apache-2.0 license ships in the published .crate.
Fill in publish metadata (authors, repository, homepage, readme, keywords, categories) across the workspace and both members.
Add CHANGELOG.md with a 0.1.0 initial release entry.
Fix clippy lints: unused enumerate index, collapsible if, Default impls for TimerTable, SimRadio, and Ctx, use RangeInclusive::contains.
Exclude examples/microwave_tui.rs from the published package. The file stays in-tree but has known unawaited async log futures that need a dedicated pass before it ships.
Apply cargo fmt across the workspace.
Hierarchical statechart codegen for Rust with:
- during: activities for state-scoped concurrent I/O
- field-list borrowing (split-borrow inside the run loop)
- embassy-first async with tokio support
- STATE_CHART const for tooling/inspection
- examples: microwave, microwave_tui, embassy_full, during_radio
