- Enter on a signal entry (net / explore) opens a modal popup to pick
power / gnd / other. Recording is deduped: a sequence of toggles on
the same signal collapses to a single `set-signal-type` line; no-op
selections record nothing.
- Bare interactive commands (the ones that open a full-screen mode)
are no longer recorded by `script-save`. Their inline forms still
are. Mutating actions inside a screen record their own canonical
line.
- Mentor importer treats signals whose name starts with `unconnected`
as no-connect — the pin is kept on the part without a signal and
tagged `ImportedUnconnected`.
- `drop_singleton_signals` runs at the end of `load`: any signal with
exactly one pin is detached (singletons are NC by definition); the
pin is tagged `DroppedSingleton`. Count is reported inline.
- `verify` gains a one-line orphan summary (imported NC / dropped
singleton totals). Pins materialised by `FillIdentityNCs` are
excluded via a `pin_map` filter — they are bridged to a real signal
on the peer module and are not real NCs at system level.
- NcOrigin tag is serialized in save snapshots as an optional 4th
field on N records (backward-compatible).

Domain
- Signal carries a SignalType (Power/GndShield/Other), auto-inferred
from the name in Signal::Signal via infer_signal_type. Override with
the new `set-signal-type` command.
- SignalType extracted to its own header so Pin can store an
`expected_signal_type` without a pins↔signals include cycle.
- pin_role(connector_type, pin_name) → SignalType lookup, called from
set-type to populate each Pin's expected_signal_type. The VPX 3U
table is currently a stub (returns Other).
- New `verify` command walks typed parts and reports pins whose
connected signal's type doesn't match the expectation.
- ODS importer no longer drops pins with empty signal column — they
stay in the part as NC, matching the rule "a pin is either NC or
connected to a signal".
- persist: new S tag for non-default signal type overrides.
Tests
- doctest v2.4.11 via FetchContent (with CMAKE_POLICY_VERSION_MINIMUM
shim, doctest's CMakeLists has a too-old floor for current CMake).
- Source files moved into a static library `essim_lib` so both `essim`
and `essim_tests` reuse the same compilation. main.cpp is the only
file kept out of the lib.
- Layer 1 (pure helpers): ToLower, LongestCommonPrefix, Tokenize,
NaturalLess (numeric/case/leading-zero edge cases + total-order
invariants), signal_type round-trips and infer_signal_type families,
VpxTransform registry + symmetry + reference-table mapping for
connector P0 row 1, IdentityTransform same-name wiring.
- Layer 2 (round-trip): build a synthetic 2-module system in code,
save → restore → assert modules / parts / connector_types / NC pins
/ signal type overrides / connections + pin_map are all preserved.
- Tui::Tokenize moved to a free function in tui_helpers so tests can
call it without dragging ftxui into the unit-test layer.
- 27 test cases, 123 assertions, ~150 ms.
