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.
