"Adjacent" read as jargon; "power management" is the standard EE umbrella
for enable/power-good/sense/fault/seq signals (cf. PMIC). Renamed across
the board: NameVerdict::PowerMgmt, stats/LoadResult field `mgmt`, analyze
tag [Power mgmt] + header "Pwr-mgmt" + glossary, load lines now say
"power-management (control/measure — kept as Other)" (TUI / script / wx
kept in sync).

Names holding both a rail token (VCC/VDD/PWR/...) and a control token
(SENSE, EN, PG, FB, OK, FAULT, ...) are signals ABOUT a rail - feedback,
enable, power-good - so their non-Power classification is confident.
They used to land in the Suspect bucket, drowning the genuine ambiguities.
- classify_signal_name(): 3-state name verdict (Rail / PowerAdjacent /
GndShield / Other) with whole-token matching (trailing digits stripped,
long lexemes also match as suffix: VSENSE, PWRGOOD, NFAULT).
infer_signal_type() becomes a thin wrapper, so the dashboard suspect
count and the export suspect column shrink automatically.
- infer_signal_types(): PowerAdjacent -> Other + new `adjacent` stat,
before the structural gate (a big-fanout sense net stays Other).
- LoadResult.adjacent rendered by all three consumers (TUI command,
script engine, wx log) - outputs kept in sync.
- analyze Types tab: new [Pwr-adjacent] rows with the deciding token,
deliberate sort order (Power, Suspect, Adjacent, Gnd), glossary entry.

Reorganise the tree into business vs frontend as separate directories:
src/core/{domain,imports,app} (was system/, imports/, app/)
src/frontends/tui/ (was tui/ + main.cpp)
tests/tui/ (the FTXUI-coupled helper test)
All cross-dir #include paths rewritten; same-dir includes untouched.
CMake: essim_core is the frontend-agnostic business library — links libzip,
pugixml and bsdl, NO GUI toolkit. Each frontend is a self-contained
src/frontends/<name>/ (own CMakeLists, toolkit, main.cpp) that links
essim_core, selected with -DESSIM_FRONTEND=<name> (default tui; 'none' = core +
tests only, no toolkit fetched). FTXUI moved into the tui frontend. Tests are
split: essim_tests links essim_core (no FTXUI), essim_tui_tests links essim_tui.
Verified: default tui build green (ctest 2/2); ESSIM_FRONTEND=none builds the
core + tests with FTXUI never fetched and no `essim` binary.

UI restructuring:
- Dashboard (`screen_dashboard.cpp`, `screen_idx = 6`) is the new home
screen at boot. Reads Overview / Health / Analysis / Modules from
the current System every frame; per-module rows list parts grouped
by `connector_type` and a Power/Gnd inference summary (yellow when
any name-Power signal is refuted). Scrollable via PgUp/PgDn/Home/End.
Letter shortcuts: `c`=console, `s`=search, `p`=plug (alias of
connect), `t`=set-type, `e`=explore, `n`=net, `a`=analyze, `q`=quit.
- Global Ctrl-P palette (`screen_palette.cpp`) — fuzzy-finds over
registered commands + module / signal names. Activation runs the
bare command or jumps to the matching screen with state seeded.
- Unified analyze screen (`screen_analyze.cpp`, `screen_idx = 7`):
tabbed layout (`Issues / Groups / Types`), Tab or ←→ to switch
tabs, ↑/↓ to navigate the focused list. Replaces the previous
shell-bouncing `[v]erify` shortcut — `verify` content is now in
the Issues tab. Types tab attaches the decision rationale to each
signal row (fan-out / voltage / hard floor).
- Context help panel: `RenderHelpPanel(title, entries)` in
`tui_helpers.{hpp,cpp}` rendered on the right of every screen.
- Console (former "log") rename: screen 0 is `[c]onsole` in the UI
and "console" in its help-panel title. The underlying screen and
the shell prompt are unchanged.
- Esc from any non-home screen returns to the dashboard. The
dashboard itself swallows Esc; quit via `q` / the `quit` command.
`quit` now calls `screen_ptr->Exit()` directly so it works from
any screen including via the palette.
Signal type inference:
- `Signal::type` defaults to `Other` — auto-inference no longer
happens at construction.
- `infer_signal_types(System*)` is called at the end of every load.
Three rules: GndShield from name alone; Power requires name match
+ a hard fan-out floor (< 3 pins = always Other, regardless of
name or voltage) + at least one positive structural signal
(fan-out ≥ 4 OR voltage pattern in the name like `3V3`, `5V`).
- Thresholds exposed in `analysis.hpp` (`POWER_FANOUT_HARD_FLOOR`,
`POWER_FANOUT_CONFIRM_MIN`, `has_voltage_pattern`) so the analyze
screen can render the same rationale without duplicating logic.
- `set-signal-type` still wins; save/restore round-trips the type.
Analysis groups & anomalies:
- New `GroupKind::DiffBus` — ≥ 2 diff pairs sharing the same
outer-stem with consecutive integer indices are aggregated into a
single bus (`MDI[0..3]_P/N`). `MDI0` and `PCIE_TX_0` index forms
both accepted. Solo pairs under a bus-able stem fall back to
`DiffPair`.
- New `AnomalyKind::DiffBusGap` for missing lanes.
Documentation:
- `DESIGN.md`: dedicated "Categorization rules (normative)" section
consolidating signal type, NC origin, signal groups, anomalies,
component kind, and connector wiring rules with exact thresholds
and decision order.
- `doc/user/analysis.md` (new): user-facing version of the same
rules in plain language. Linked from `doc/user/index.md`.
Tests: +6 new cases (62 total). Adjusted `test_persist.cpp` to set
the signal type explicitly in the fixture (no more auto-inference).

- New `src/system/analysis.{hpp,cpp}` — stateless post-processing pass
`analyze_system(System*) → AnalysisReport`. Per-module detection of
signal groups and anomalies; pure read, re-runnable.
- Groups: diff pairs (`*_P` / `*_N`, case-insensitive), buses
(`NAME[N]` or strict `NAME_N` — the `_` before digits is required
so names like `GETH_01_VDD12` are not misread as a bus).
- Anomalies: `DiffPairOrphan` (asymmetric: only `_P` without `_N` is
reported — `_N` alone is overloaded with active-low semantics and
floods the output with false positives), `BusGap` (missing index
inside a detected `[lo..hi]`).
- Noise filters: signals starting with `$` (Mentor internals) are
skipped wholesale.
- New `analyze` shell command — prints groups sorted by module +
label, then anomalies. Sized for the upcoming dashboard.
- `tests/test_analysis.cpp` — 8 cases covering both detectors, false-
positive guards (no-underscore digits, `$`-prefixed internals), and
per-module scoping.
- `tests/test_nc_origin.cpp` — completes the prior NC-tagging commit
with round-trip + drop_singleton_signals coverage.
- DESIGN.md updated: layout entry for `analysis.{hpp,cpp}` and new
section explaining the pass; NC-origin paragraph aligned with the
actual tag semantics and the verify three-pass summary.
