History-free snapshot of the private development repository at cbe45c5 (2026-09-09). Code, docs and public catalogue only; no plant or job knowledge layers, no client or job names (tools/scrub.py clean). The intro deck is left out of this snapshot because its slide images could not be checked for job drawings.

"""Tests for the panelanalysis/1 SOLVE path -- the self-weight Handling model.
|
|
|
|
Loaded by path, exactly like `test_panelanalysis.py` beside it: this is host
|
|
CPython (it imports `panellift`, dataclasses, typing syntax) sitting in an
|
|
IronPython 2.7 extension, and it reaches the tool through `tools/`, which the
|
|
sibling knowledge merge in `deckcheck.py` puts the `vibe` stub in place for.
|
|
|
|
The four things the Stage 0 brief asked these to nail down:
|
|
|
|
1. the self-weight solve reactions sum to the load, the moment diagram is
|
|
real, and the per-station capacity comes from `panellift`;
|
|
2. editing the deck's supports and re-solving changes the reactions -- the
|
|
round-trip the owner wants;
|
|
3. a deck with fewer than two supports is REFUSED loudly (panellift's own
|
|
"a supported stage needs at least two supports"), surfaced as NOT JUDGED
|
|
on the page, never a traceback and never a silent OK;
|
|
4. missing prestress dashes with panellift's reason, never a zero; the
|
|
In-Place sections are explicit placeholders; zero CJK on the page.
|
|
|
|
Everything written at runtime goes under `tmp_path`; nothing touches the
|
|
working directory.
