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).

- 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.

Replace `◀` / `▶` (often rendered as double-width emoji glyphs) with
`←` / `→` (single-cell in every monospace font) so the box borders
line up correctly.

- 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).

- `essim --commands-md [file]` instantiates the Tui, calls
`Tui::DumpCommandsMd(ostream&)` which iterates the live registry and
emits Markdown grouped by interactive/other, then exits. Single
source of truth: a new `CommandSpec` field surfaces automatically.
- CMake `doc` target now `DEPENDS essim` and chains:
doxygen → gen_api_md.py → doc/api/
essim --commands-md → doc/user/commands.md
- `doc/user/` adds:
- index.md (hand-written) — first session, interactive-screen
conventions, save/restore/replay overview.
- scripting.md (hand-written) — `set`/`$var` expansion semantics,
`source` event-paced execution, script-save denylist, worked
example pointing at test/system.essim.
- commands.md (auto-generated, regenerated by the `doc` target).
- Top-level README refocused on quick start; pointers to the new
doc tree (user/, api/, DESIGN.md) instead of an inline command table.
- doc/README.md and DESIGN.md document the two-pipeline doc workflow.
- `test/system.essim` and user docs anonymised: bkp → backplane,
vdn1/2/3 → payload1/2/3, cb3p → payload4, bpb/cob/ssu →
peripheral1/2/3; netlist file names + variable names + paths all
replaced with generic equivalents.

`cmake --build build --target doc` runs Doxygen to produce XML, then
`doc/gen_api_md.py` (~330 lines, stdlib-only) emits a Markdown tree
under `doc/api/` that gitea renders directly in its file browser.
- 24 class/struct pages + 51 source-file pages + indices, with source
links of the form `../../../../src/...#L42` that gitea turns into
clickable line-anchored links.
- Doxyfile.in templated by CMake (XML-only output to build/doc/xml/).
- Pure Python emitter, zero external deps — no doxybook2 (not packaged
on Arch) and no moxygen (avoids Node).
- Target gracefully disabled if Doxygen or Python 3 is missing at
configure time; regular build target unaffected.
