fix: the manual's figures carry a description, and the check that would have caught them
Three pages opened in nothing in Yelp -- overview (twice), math, trigger -- while every check passed. They are exactly the pages whose <figure> had a sentence for a <title> and no <desc>: a Mallard <figure> is title?, desc?, media, and the page is refused without the description. The idiomatic shape, as the shipped sets on this machine write it, moves the sentence into <desc> and leaves the <title> a name. Note trigger-capture.png is referenced from both overview and trigger, which is why those two pages are the ones that were noticed. The gap was in the check, not in its reach: tools/check_help.sh ran links/media/orphans/ids and an HTML render, and all four are silent about a page that is well linked, well parsed and unrenderable. `yelp-check validate` is the one that would have caught it, and it cannot run here: it generates the RelaxNG schema with xsltproc, but the schema includes the base grammar over the network and this machine's libxml cannot fetch. So the structural rules this project has actually needed are checked with xmllint's XPath, offline, each written after a page needed it. One trap, paid for while writing it: a Mallard page declares xmlns="http://projectmallard.org/1.0/", XPath 1.0 has no default namespace, so `//figure` matches nothing and every rule passes -- the first version of this check reported "ok" for the very defect it was written for. Every expression uses local-name() for that reason, and the script says so where the next reader will be. Verified: on the committed pages the rules exit 1 and name the three figures, which is the failing-before case kept as the regression test; on the fixed pages all five rules pass and yelp-build renders all 15; make -C build test-help goes from red to green. |

feat: the manual is a Mallard set opened in Yelp, not a GResource in the binary
The help was 14 Pango-markup `.txt` bodies in a second GResource, drawn into a paged `GtkWindow` built in `help_window.cpp`. That made F1 a viewer of ours with no search index, no cross-references and no translation, and it kept the manual in the *binary* when every other desktop application's is a document on disk. It is now a real Mallard set: help/C/org.udpscope.app/ index.page + 14 topic pages + figures/*.png and `show_help()` hands `help:org.udpscope.app` to whatever the desktop registered for the `help:` scheme -- Yelp on GNOME -- through a `GtkUriLauncher`, reporting a launch failure with a `GtkAlertDialog` rather than a click that silently does nothing. The paged window's builder, the page table and `help_self_check()`'s markup validation are gone with the resource. The document identifier is the desktop file's own basename (its desktop-file id), derived in CMakeLists from `data/org.udpscope.app.desktop.in`, so the same string is the `.desktop` name, the GApplication id and the install directory at once. The set is installed by a new `install()` rule to `<datadir>/help/C/org.udpscope.app/` -- where the freedesktop Help System Specification's `help:` URI resolves `help:<id>` -- so the manual is read from a datadir by another process even though the binary has no install step. `UDPSCOPE_HELP_NAME` and `UDPSCOPE_HELP_DIR` are compiled in from that one place. The 14 pages were migrated fact for fact, but restructured the Mallard way: a `<desc>` per page (what a search result shows), `<steps>` for procedures, `<terms>` for option lists, `<gui>`/`<key>`/`<keyseq>` for interface words and keys, `<note>` for the asides, and a topic graph via `<link type="guide" xref="index#main"/>`. The figures are annotated screenshots produced by `tools/make-help-shots.sh`, which drives the app headlessly against `tools/mock_udpstreamer.py` and draws the boxes with ImageMagick; the side panel's box is measured from the app's own `side=NNNx` dump reading, the header and status bands come from a documented table, and a crop whose standard deviation is 0 fails the script. `cmake --build build --target test-help` checks the set the way `test-ui` checks the `.ui` files: `yelp-check`'s offline subcommands (links, media, orphans, ids) and a `yelp-build html` render. `yelp-check validate` is deliberately absent -- it fetches the Mallard RelaxNG schema over the network and fails offline for that reason, not for a fault in the pages. The `[help]` probe reading changes with the resource it was written for. `parsed == pages` over in-binary markup cannot exist now, so `help_self_check()` scans `UDPSCOPE_HELP_DIR` and the line reads `topics=14 index=1 figures=3`; `topics=0 index=0` is the manual missing from the tree, which is the finding the old count named. Verified: clean build with the documented three warnings (the help bundle's `-Woverlength-strings` is gone, so the baseline moves from four to three); test-ui 14/14; test-help clean (the four subcommands and 15 pages rendered); a temp-prefix install lands 15 `.page` files and 3 figures at `share/help/C/org.udpscope.app/`; the headless run reads `[help] topics=14 index=1 figures=3 dir=...` with 0 Gtk-CRITICAL. Yelp's own window could not be exercised on this box -- it starts under Xvfb, activates its portals and never maps, the same WebKit/portal limitation that stops a grab -- so its rendering and its search index are unverified here; the content pipeline was (`yelp-build` renders the whole set). Docs: the manual's build/install/open story in `build-and-run.md` and README; the warning baseline in `verification.md`/CLAUDE.md; the help bullets in `invariants-gtk-and-chrome.md`; the `[help]` line in `probe-readings.md`. |
