chore(release): v0.12.0 — DWARF source-line debugging (VCR-DBG-001, #242) - #440
Merged
Conversation
, #394) First release of the north-star verified-codegen campaign. Pin sweep 0.11.51 -> 0.12.0 (workspace + all path-dep versions + MODULE.bazel + Cargo.lock), CHANGELOG, and VCR-DBG-001 roadmap status -> implemented. Ships: - VCR-DBG-001 `--debug-line` DWARF emission (PR A #427 / B #429 / C #430): debugger-readable .debug_* mapping ARM .text -> wasm source lines, with .rel.debug_* relocations verified end-to-end against arm-none-eabi-ld. Purely additive; default build bit-identical. - VCR-MEM-001 layer-2 frozen-safe budget decision logic + oracles (#421-#425). - gimli 0.33 adaptation (#439) + wast 252 (#438). Minor bump: new user-facing `--debug-line` feature (semver-correct). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
