rob thijssen	302ccfb982	refactor(neuron): introduce InferenceEvent + wire projection layer ... Step 1 of the OpenAI Responses API rollout. Pure refactor — no new endpoints, no behaviour change on the wire. Lays the seam for emitting Responses-shaped streaming events from the same harness output as chat completions in Step 2. - New `neuron::wire` module tree: - `wire::event::InferenceEvent` — format-agnostic enum (Start, TextDelta, ReasoningDelta, Finish) the candle harness now emits as its native streaming currency. - `wire::event::FinishReason` — typed reason that maps cleanly onto OpenAI `finish_reason`, OpenAI Responses `status`, and Anthropic `stop_reason` strings. - `wire::openai_chat::project_chat_stream` — async task that consumes an InferenceEvent receiver and produces a ChatCompletionChunk receiver, stamping per-request metadata (id, created, model_id) onto every chunk. Output matches the pre-refactor wire shape bit-for-bit. - candle.rs refactored to emit InferenceEvent on its internal channel through all three streaming paths (CPU run_inference_streaming, CUDA single-GPU stream_inference_via_worker, CUDA TP chat_completion_tp_stream). The streaming functions lost their id/created/model_id parameters since wire-format metadata now lives in the projector. - emit_delta + emit_delta_blocking simplified to single-purpose TextDelta emitters with no wire-format coupling. - chat_completion_stream wraps the InferenceEvent receiver in wire_chat::project_chat_stream before returning so the /v1/chat/completions HTTP handler keeps consuming ChatCompletionChunks unchanged. External signature preserved. Also fixes a pre-existing helexa-acp test race (three modules each declared their own static LOCK for HOME mutation, so cross-module parallelism flaked tests that read HOME at runtime). Consolidated onto a single crate-wide path_util::ENV_LOCK. 122 helexa-acp tests + 44 neuron tests pass (5 new wire projection tests). fmt + clippy --workspace -- -D warnings clean. Ran helexa-acp suite 3x to confirm the env race is closed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-29 11:30:17 +03:00
rob thijssen	b9016571f6	feat(helexa-acp): expand ~ / $HOME and fall back to local fs on ACP read errors ... Two related polish fixes for daily use: - New `path_util` module expands `~`, `~/…`, `$HOME`, and `$HOME/…` prefixes in every tool that takes a path (read_file, write_file, edit_file, list_dir, bash cwd). The expansion is also applied to the plan-mode write gate so `~/.local/share/helexa-acp/plans/…` comparisons behave correctly regardless of which form the model emits. - `read_file` now falls back to `std::fs::read_to_string` when ACP's `fs/read_text_file` errors out. Zed's workspace-scoped read was the source of "model can't see ~/git/architecture/generic.md" when the session cwd is a different project; the fallback lets the agent pull in shared material that lives outside the active workspace, the same way `list_dir` already does via local `std::fs::read_dir`. Local fallback honours line/limit args. The fallback also produces a combined error message when both ACP and local-fs reads fail, so the model sees what actually broke rather than just the ACP-side error. 14 new unit tests cover path_util's prefix matrix, fallback success/failure paths, and the line/limit slicing in fallback.
