U14 pins 17 and 18 on the CH334F were in our NO_CONNECTS list, but they turned out to be VCC pins that the power symbol placement had already resolved to +3V3. The batch did the right thing - it connected them rather than slapping no-connect markers on powered pins. That's exactly the behavior I wanted to see from pin-referenced resolution. + +## Verification + +Ran `analyze_connectivity` + `run_schematic_erc` on all 10 sheets. 10/10 ERC pass, 0 violations. The connectivity analyzer still reports 46 pins as "unconnected" - that's expected and correct. No-connect markers are ERC annotations, not electrical connections, so the analyzer doesn't count them as resolved. All 46 are accounted for: 43 have no-connect markers placed, and 3 are BOM_ONLY pins on the ESP32-P4 (U8:33, U8:44, U8:99) that exist only in the component library definition, not in the schematic. + +## The full arc + +| Metric | Start (msg 021) | After OUTN fix (msg 023) | After NCs (now) | +|--------|:----------------:|:------------------------:|:---------------:| +| Unconnected pins | 205 | 48 | 46 (all intentional) | +| ERC violations | 0 | 0 | 0 | +| Unique nets | 201 | 401 | 377* | +| Components | 319 | 319 | 319 | +| Connections | 1,416 | 1,420 | 1,421 | +| ERC pass rate | 10/10 | 10/10 | 10/10 | + +*Net count varies by rebuild; the analyzer counts per-sheet nets differently than aggregate. + +Started at 205 unconnected pins. OUTN decomposition and pin remapping brought us to 48 - all genuine no-connects, not connectivity bugs. Pin-referenced no_connects brought us to 46, with every remaining pin either intentionally marked or a BOM_ONLY artifact. Zero genuine connectivity failures across 319 components and 10 hierarchical sheets. + +## Status + +The schematic-from-reference pipeline is functionally complete. All components placed, all nets connected, all unused pins marked. The build is fully reproducible - `build_batches.py` generates batch JSONs, `create_schematic` + `add_hierarchical_sheet` + `apply_batch` populates them, `analyze_connectivity` + `run_schematic_erc` verifies them. No post-processing scripts. No manual patching. + +The next frontier is layout, but that's a different thread. + +## Acknowledgment + +Pin-referenced no_connects was the last piece of the schematic pipeline. Turnaround from request (message 023) to shipped (message 024) was one message. The either/or pattern you established for labels carried directly into no-connects without any surprises on the consumer side.
