"dropped detail:" said nothing about what those pins are. They were detached
by drop_singleton_signals because each was the lone pin on its net (nowhere to
connect → NC). Relabel to "dropped — lone pin on its net (→ NC):".

check_bsdl_completeness(System*): for each BSDL-attached part, re-parse the
.bsd and report the device power/ground ports with no matching pin on the
netlist part (matched by port name or physical pad) — a rail the schematic
symbol is missing. One aggregated BsdlPinMissing per part; restricted to
power/ground so unused I/O balls don't create noise. Surfaced as a 7th verify
pass and in the analyze/dashboard model counts. 76 cases / 327 assertions
green; the real 8-card system reports 0 (all FPGA rails present). This closes
out P3.

The analyze screen's Issues pane now lists the model-driven checks
(check_pin_specs / check_jtag_chain / check_source_conflicts) alongside the
pin-role, net-mix and structural ones, with an "N model" count in the header;
the dashboard gains a "model:" health row. check_pin_specs/check_jtag_chain
take an optional precomputed net list, so verify, analyze and the dashboard
each compute the nets once and reuse them across checks instead of redoing the
transitive closure per check. Unit tests (75) green; verify output unchanged.

Introduce PinSpec (function/direction/pad/source) as the "expected" half of
pin verification, and make Pin::expected_signal_type() a derived accessor over
spec.function. pin_role() now returns a PinSpec; the connector layout (and,
later, BSDL) feed the same structure.
Pure refactor, behaviour-preserving: vpx_3u_role is still a stub, so every pin
maps to Other exactly as before. The new `pad` field will carry the BSDL
physical pin; direction/function will unlock contention/undriven/NC checks.

ODS sheets now carry a per-connection meta block (Connection / Transform
/ Left / Right) above the data; the header row anchors the freeze, the
auto-filter range, and the zebra striping. CSV stays a single flat
15-column table whose names match the ODS headers exactly.

New user-facing features:
- `export connections <file>` writes a tabular dump of every wire pair:
connection, transform, left/right module/part/pin/signal/type/suspect,
mixed-types flag. Dispatch on extension: `.csv` (flat file) or `.ods`
(one sheet per connection). Any other extension shows an error and
writes nothing.
- Bare `export` (or dashboard `[x]`, or palette `export`) opens an
interactive file-picker dialog with a CSV/ODS toggle at the top.
Picking a filter rewrites the filename's extension. Last-used
directory and filename are remembered per-call-site.
- Two new CLI flags on the binary: `--source FILE` to run a script at
boot, `--restore FILE` to restore a snapshot at boot. Combinable.
Reusable infrastructure:
- `OdsWriter` (`src/imports/ods_writer.{hpp,cpp}`): minimal .ods writer
using libzip + pugixml (already in the build for the importer).
Multi-sheet workbook of string cells. ~180 lines, no new dep.
- Generic file-picker dialog (`screen_filedialog.cpp`): one Modal
reused for any "pick a path" interaction via
`OpenFileDialog(title, persist_key, default_filename, filters, cb)`.
Validates the picked extension against the filter whitelist;
unknown ones stay in the dialog with a status message. Persists
(dir, filename) per `persist_key`.
- Generic error modal (`screen_error.cpp`, `ShowError(msg)`): centred
red-titled popup, dismissable with Esc/Enter. Used by the export
failures (open-for-write, ODS save, unknown extension/kind);
ready for adoption elsewhere.
- Per-key path persistence (`SaveLastUsed`/`LoadLastUsed` in
`shell.cpp`): two-line file per key under the user-data dir.
- `UserDataDir()` extracted from the history path helper so the new
per-key persistence shares the same XDG/AppData logic.
- New help-screen topic "Export"; user-facing `doc/user/analysis.md`
gains an "Exporting" section; `DESIGN.md` gains a generics
section covering the dialog / error modal / persistence / ODS
writer; `DumpCommandsMd` now respects the `hidden` flag (the
`connect` alias no longer appears in the auto-gen reference).

The analyze screen already used `[Suspect Power]`; the dashboard and
the `load` summary still said 'refuted', which felt harsher and was
out of sync. Now consistent everywhere.
- Dashboard module row: `power: X confirmed, Y suspect gnd: K`.
- Load summary: `types: N power, M gnd, K suspect Power (name only
— kept as Other)`.
Internal variable renamed `n_pwr_refuted` → `n_pwr_suspect`.

- New `screen_help.cpp` (`screen_idx = 6`). Left column: menu of 13
topics (Overview, Dashboard, Console, Palette, Explore,
Connect/plug, set-connector-type, Signal types, NC pins, Analyze,
Scripting, Save/restore, Quitting). Centre column: paragraphs of
the focused topic, word-wrapped via `paragraph()` and scrollable.
Right column: standard help panel.
- `help` bare → opens the screen; `help <name>` keeps the existing
textual command-help behaviour for scripts.
- Dashboard `[h]` shortcut opens the screen, and the dashboard help
panel (both the loaded and the no-system branch) lists it.
- Console: title gets the standard breadcrumb (`essim → console —
type commands, read textual output`). Module/connection counters
moved off (they live on the dashboard now).
- Explore Enter on a part jumps to `set-connector-type` with the
exact-match index pre-computed in the filtered list (avoids the
substring-match collision where `J20` would land on the wrong
row when J200/J21 also matched).
- set-connector-type screen: bind `focused_entry` to `selected` on
both menus so the cursor `>` tracks the selected row when state
is pre-seeded from outside. Right column drops its strict
`size(WIDTH, EQUAL, 40)` in favour of `flex`, and the `new type`
input uses `xflex` so it actually stretches across the column.
- Esc on `set-connector-type` honours `screen_back_idx` — when
entered via Enter on a part in `explore`, Esc returns to explore;
otherwise it returns to the dashboard like every other screen.
Standalone command entries explicitly reset the back-link.
- Net-member rows in the explore detail pane carry a
`module\tsignal` payload so Enter opens the popup scoped to the
peer module rather than mis-firing on the locally selected one.
Same scheme for local-pin rows.

`explore` was already a superset of `search` (4 columns: module → type
→ filtered children → detail, with parts/signals/connections — vs
search's 2 columns of parts/signals only). It now also subsumes the
former `net` screen: when a signal entry is selected, the detail pane
shows the local pins followed by a `Net members (across connections)`
section listing every `(module, signal, type)` reachable through the
BFS over `Connection::pin_map`, with the count + dominant type and an
INCONSISTENT flag in the signal-detail header.
Removed:
- `src/tui/screen_search.cpp`, `src/tui/screen_net.cpp`.
- `commands["search"]`, `commands["net"]` (including its textual
inline form). The `find_net` / `Net` API stays for explore's BFS
panel and the analyze screen's net-mix check.
- `[s]` and `[n]` letter shortcuts on the dashboard.
- `net_*` and `search_*` state members + builders + constructor
inits.
screen_idx renumbering (the slots vacated by search + net are
removed, not left dead):
0 = console (unchanged)
1 = connect
2 = set-connector-type
3 = explore (unchanged number, but now subsumes search + net)
4 = dashboard (boot)
5 = analyze
Palette signal items now jump to `explore` prefilled on the signals
tab with the child filter seeded to the exact signal name; the BFS
section in the detail pane is what shows the cross-module net.
Net-member rows in the detail pane are deliberately read-only for
now (Enter is a no-op): the signal-type popup is scoped to the
currently selected module, so opening it on a peer-module member
would mis-fire. Cross-module Enter navigation can come later if
needed.
DESIGN.md and user docs updated accordingly.

- Command renamed from `set-type` to `set-connector-type` for
clarity (the previous name was ambiguous — "type" of what?). No
legacy alias kept; old scripts that still used `set-type` must be
migrated. `test/system.essim` and all user/design docs updated.
- Help panel (RenderHelpPanel) now wraps in borderRounded with a
centred bold title, so it is visually distinct from the main
content on every screen. Width bumped from 30 to 32 to include
the border.
- Analyze screen's Types tab gains a sibling "type glossary" panel
(also borderRounded, only visible when the Types tab is focused)
that explains Power / Suspect Power / Hard floor / Gnd in plain
language using `paragraph()` for clean word-wrap.

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).
