UPGRADE.md

# Version 0.1.5: missing-connection errors resolved

Updated to tscircuit 0.0.2615, @tscircuit/core 0.0.1956, and @tscircuit/checks 0.0.208. Explicit-entry `tsci build index.circuit.tsx --site` exits 0 with zero errors; all 34 missing-connection diagnostics from 0.0.2611 are gone. TypeScript, connectivity patch regressions, and LED polarity/placement regression pass. Existing supplier-footprint and metadata warnings remain. Board source and routed copper were unchanged. This dependency update is included in package version 0.1.5.

Older geometry/assembly reports below and elsewhere retain their original build hashes. The DDR reference-plane/SI concern is not resolved by this checker update.

## Previous published upgrade

# Dependency upgrade validation — 0.1.4

Updated tscircuit from 0.0.2594 to 0.0.2611 and the explicit @tscircuit/core pin from 0.0.1944 to 0.0.1953. Installed @tscircuit/checks is 0.0.207. Board source and routed copper are unchanged from 0.1.3.

TypeScript, connectivity patch regressions, and the LED polarity/placement regression pass. The explicit-entry site build exits 1 with 34 pcb_trace_error missing-connection diagnostics. Independent copper audit on that same build passes: all 138 nets connected, zero clearance violations. The discrepancy has not yet been resolved; a passing geometric audit does not make the native build passing.

The older validation/assembly artifacts in this release describe the previously validated build. They are retained as historical evidence, not validation of the upgraded runtime. The existing DDR signal-integrity/reference-plane concern remains.
