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.

- ODS importer (libzip + pugixml): each sheet → Part, rows → Pin/Signal.
- save / restore commands: tab-delimited snapshot of modules, parts,
signals, connections + pin_map. `restore` replaces the System.
- source / script-save: replay a file of commands; record canonical
commands since last `new` for replay later. Interactive screens
refused during source. `explore` marked non-scriptable.
- TUI screen_explore: 4 columns (modules, type, children, detail) with
filters on children and detail; detail is a Menu so arrows scroll
long pin lists.
- Connector types & transforms: each Part carries a `connector_type`
string. `set-type` validates the part's pin layout against the type
(cols set check). `connect` strict pair: rejects when lookup falls
back to identity unless types are both empty AND pin sets match.
- VPX 3U transforms: 3 registered pairs (vpx-3u-bkp-pN ↔ vpx-3u-payload-pN,
N=0/1/2) with row-pattern correspondence tables ported from the user's
Python reference.
- Code split for maintainability: src/tui/{shell,completion,commands,
screen_main,screen_search,screen_connect,screen_settype,screen_explore,
tui_helpers}.cpp.
- Bug fixes: Module::add(Part*) override sets part->prnt (was always
null, breaking save's W lines). Defensive guards in explore against
empty Menu lists. Renderer wrapped in try/catch so domain throws
surface as on-screen errors instead of SIGABRT.

- ftxui v6.1.9 fetched at configure time; vendored .a + headers dropped.
- TUI: visualisation area on top, input prompt at the bottom; ↑/↓ history,
Tab completion (commands + file paths), Esc cancels prompts. History is
persisted (XDG on Linux, %LOCALAPPDATA% on Windows when ported).
- Command registry: `new`, `load`, `search`, `clear`, `help`, `quit`/`exit`.
Inline params or interactive prompts; either way the canonical inline
form is what gets stored in history.
- `search`: second full-screen mode with module + parts/signals menus and
a live-filtered list; Tab cycles focus, Esc returns to the main shell.
- Domain: `System::modules()` accessor + `SystemElementContainer::size()`
to support load summary + search.
