# Changelog
## [0.20.0] — 2026-08-07
### Fixed
- fix: clear the warnings the flag removal left behind
## [0.19.7] — 2026-07-28
## [0.19.6] — 2026-07-13
## [0.19.5] — 2026-07-10
### Fixed
- fix(claude-code): classify prompt-too-long as ContextLength (400), not 502
- fix(clippy): backtick doc addrs, is_ok_and, unwrap-free auth tests CI clippy --all-targets flagged doc_markdown (127.0.0.0/8, ::1) + map().unwrap_or -> is_ok_and in is_loopback_host; arch-validation counted 3 test unwrap()s — replaced with matches!. Fixes the 52d04d6 CI failure.
### Other
- test(copilot_headless): annotate safe test unwraps for arch-validation 15 test-only unwrap sites (tempdir/fs/serde setup) get same-line // Safe: comments; zero flagged remain
## [0.19.4] — 2026-06-29
### Added
- feat(ci): auto-validate Homebrew install after release release.yml now calls homebrew.yml (reusable workflow_call) as a final gated job once the tap formula is pushed, passing the released version for an exact match; drops the vestigial push:tags trigger (GITHUB_TOKEN tag pushes never fired it and would race the formula update). workflow_dispatch retained for manual runs.
### Fixed
- fix(copilot-headless): route ACP sessions to the configured model via settings.json copilot --acp routes by ~/.copilot/settings.json "model" and ignores both the session/new model field and the --model flag (cosmetic label only); write the model into settings.json before each spawn (preserving other keys), track the warm-process model and respawn on change, and log the real routing model — fixes ACP sessions silently falling through to the account GPT/Gemini default while logs claimed the requested model.
- fix(ci): trust dravr-ai tap for Homebrew 6.0 install (ubuntu) Homebrew 6.0 refuses untrusted third-party taps; brew trust dravr-ai/tap (|| true for older brew) before install. Last of 4 Homebrew jobs.
- fix(ci): make Homebrew test harness pass (llvm-nm, linuxbrew PATH, 503 health) macOS FFI symbols via toolchain llvm-nm (Apple nm can't read Rust 1.96 LLVM objects); add linuxbrew to PATH on ubuntu (brew not found); smoke test accepts degraded 503 /health (no provider CLIs in CI) by dropping curl -f. All validated locally.
## [0.19.3] — 2026-06-22
### Added
- feat(mcp): migrate to dravr-tronc 0.5.3; release v0.19.2 ActiveConfig->interior RwLock (provider/model/multiplex accessors &self async); init protocolVersion now 2025-11-25; -mcp/-server only.
- feat(release): adopt dravr-tronc 0.3 via coordinated republish (embacle-mcp/server 0.19.1) Republish embacle-mcp+embacle-server 0.19.1 on tronc 0.3.1 so the publish graph resolves a single tronc version; root embacle (no tronc dep) stays 0.19.0.
### Fixed
- fix(ci): combine publish dry-run into one workspace invocation Per-crate dry-run resolved internal embacle dep vs crates.io (only 0.19.0 there, not the unpublished 0.19.2) and failed; co-publishing all three resolves siblings locally. Verified cargo 1.96.0 exit 0.
### Other
- style(lints): enforce error-handling restriction lints; create_runner_with_config -> Result Sole prod fix: ClaudeWeb embedded-config parse propagated via ? (was expect); crate-root cfg_attr(test, allow) + tests/examples allow attrs; --all-targets clippy green.
- Revert "chore(deps): bump dravr-tronc 0.2 -> 0.3" (publish-dry-run version skew) embacle-server publishes against registry embacle-mcp 0.19.0 (tronc 0.2) -> two tronc versions clash; needs a coordinated member-crate release to adopt 0.3.
- chore(deps): bump dravr-tronc 0.2 -> 0.3 (now published to crates.io) Server/mcp crates compile against 0.3.1; picks up otel + NotifyLayer + error-handling fixes.
## [0.19.2] — 2026-06-19
### Changed
- deps: migrate `embacle-mcp` and `embacle-server` to dravr-tronc 0.5.3 (dual-era
MCP engine). tronc 0.5 hands tools/handlers a shared `&Arc<ServerState>` with no
outer `RwLock`, so the active provider/model/multiplex config moved to a
per-field interior `RwLock<ActiveConfig>`; those accessors are now `&self` async
(the runner cache was already interior `Mutex`). All three crates aligned to a
single workspace version. The core `embacle` crate is unchanged.
## [0.19.0] — 2026-06-07
## [0.18.0] — 2026-06-06
### Added
- feat(acp): per-request mcp_servers for native Copilot ACP tool calling ChatRequest.mcp_servers flows into session/new; opt-in mcp_tool_calling re-enables SDK_TOOL_CALLING to route tool turns through converse().
