The architecture Markdown embeds these 22 SVG figures. Matching PNG previews

are provided for viewers that do not support SVG. Diagrams describe the working
|

architecture; component qualification and schematic-release requirements remain

## Editing and regeneration
|
||||||
|
|
||||||
|
- The 12 block figures have editable `.drawio` sources. Open them in draw.io.
|
||||||
|
`build_blocks.py` recreates their baseline layout and `block-connections.json`.
|
||||||
|
Running it overwrites manual layout edits, so update the generator when those
|
||||||
|
edits should be reproducible, or export the edited `.drawio` directly.
|
||||||
|
- The 10 circuit/logic figures are generated by `build_circuits.py`, with a
|
||||||
|
separate `*.topology.json` connection manifest for each figure. Change the
|
||||||
|
relevant component/net definitions and layout together in that script;
|
||||||
|
rerunning it overwrites the generated topology and images. JSON is a review
|
||||||
|
manifest, not an independently interpreted rendering input.
|
||||||
|
- Reference designators introduced by these drawings are documentation labels,
|
||||||
|
not KiCad assignments. Named continuation ports are electrically identical
|
||||||
|
only when their names match within the documented domain.
|
||||||
|
|
||||||
|
Run from this directory using the configured schematic environment:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python build_blocks.py
|
||||||
|
~/.venvs/codex-schematics/bin/python export_blocks.py
|
||||||
|
~/.venvs/codex-schematics/bin/python build_circuits.py
|
||||||
|
```
|
||||||
|
|
||||||
|
`export_blocks.py` requires the installed draw.io desktop renderer; restricted
|
||||||
|
Electron sandboxes may require an authorized external execution. It exports
|
||||||
|
only `.drawio` inputs, keeps editable sources, checks for native SVG text, and
|
||||||
|
creates PNG previews. The circuit builder uses Schemdraw and CairoSVG.
|
||||||
|
Inspect changed figures at their intended embedded size after rebuilding.
|
||||||
|
|
||||||
|
Validate each circuit manifest with the installed topology validator:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
~/.venvs/codex-schematics/bin/python \
|
||||||
|
~/.codex/skills/electronics-schematic-rendering/scripts/validate_topology.py \
|
||||||
|
analog-input.topology.json
|
||||||
|
```
|
||||||
|
|
||||||
|
## Source clarifications in this redraw
|
||||||
|
|
||||||
|
- The former power-tree branch labelled `+5V_AUX` after 3.3 V filtering is now
|
||||||
|
`+3V3_ANA`, matching the dedicated rail description. `+5V_AUX` remains a
|
||||||
|
protected branch of `+5V_MAIN`.
|
||||||
|
- The passive ADC drawing now shows `C_HOLD` as a shunt capacitor after the
|
||||||
|
small isolation resistor specified in the prose. It does not add a separate
|
||||||
|
connector-side `R_PROT`. Exact values remain unspecified.
|
||||||
|
- The Hall-input drawing separates sensor supply, sensor return and signal;
|
||||||
|
the original ASCII alignment could suggest an unintended join. The pull-up,
|
||||||
|
divider and parallel filter follow the existing prose.
|
||||||
|
- The deadman equations are unchanged. Contact observations, permission gates
|
||||||
|
and output gates occupy separate figures; shared net names connect them.
|
||||||
|
- `VBG_LOCAL_KELVIN` labels the documented local ignition reference at the
|
||||||
|
`IGN_PGND` joining point. `LOCAL_GND` in the sink-command figure denotes the
|
||||||
|
TLE9104SH local ground reference. Neither denotes a new remote ground path.
|
||||||
|
- The obsolete reference to a missing figure in `DIGITAL_INPUTS.md` was removed.
|
||||||
|
That module remains described by its existing component-level prose.
|
||||||
|
|
||||||
|
Protection blocks whose devices or ratings remain unselected are deliberately
|
||||||
|
functional. Supply-loss behavior, real pin mappings, ratings and physical fault
|
||||||
|
responses still require the validation specified in the module documents.
